  The installation location of the above-described crime prevention device is various, indoor or outdoor, and particularly when installed outdoors, the influence of the surrounding environmental noise is large, and the alarm sound output from the sound output unit 5 is It was buried in environmental noise and could not be heard enough.

  Therefore, the volume level of the alarm sound from the sound output unit 5 is output at a high volume of about 90 dB, for example, so that the alarm sound from the sound output unit 5 can be heard reliably even in an environment where a certain amount of environmental noise exists. There are also crime prevention devices that make it possible to hear alarm sounds reliably, but simple crime prevention devices using pyroelectric infrared sensors in the human sensor unit 2 can detect animals such as dogs and cats other than humans. When a plant such as a plant in the detection area fluctuates in the wind, it will often cause false alarms such as detecting its movement, and a loud alarm sound will be output each time, causing problems in the neighborhood. there were.

  In addition, the target to hear the alarm sound output from the security device is an intruder trying to enter the house where the security device is installed, a householder living in the house, a nearby resident and a passerby, These subjects have various ages and genders, including elderly people. According to medical knowledge, humans generally lose their auditory abilities as they get older, and the deterioration of their auditory sensation is particularly pronounced for high-frequency sounds. Therefore, in order to make it easier for elderly people to hear, it is preferable to set the frequency of the output sound from the security device lower, but outdoor environmental noise such as residential areas contains a lot of low-frequency noise, The sound in the low frequency range is easily affected by environmental noise, and there is a problem that it is difficult for elderly people to hear the output sound from the security device.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to provide a crime prevention device and an illumination that make it easy to hear an alarm sound even in the presence of environmental noise without increasing the volume of the output sound. To provide an instrument.

In order to achieve the above object, the invention of claim 1 comprises at least means for detecting the presence of a person in a predetermined detection area and outputting human body detection information, and surrounding environmental information including human body detection information. A sensor unit for detecting, a plurality of sound output units for outputting alarm sounds, and a control unit for outputting an alarm sound from the sound output unit when human body detection information is input from the sensor unit, the control unit comprising at least While changing the frequency of the alarm sound with time, the lower the frequency of the alarm sound, the larger the volume of the alarm sound , and the control unit differs from each sound output unit in at least one of frequency and volume. Each of the alarm sounds is output .

  According to a second aspect of the present invention, in the first aspect of the invention, the control unit prepares in advance a plurality of output sounds having different frequencies as the alarm sound, and alternatively selects the sound from the plurality of output sounds to output the sound. The frequency of the alarm sound is changed by outputting from the unit.

  The invention of claim 3 is characterized in that, in the invention of claim 2, the control unit periodically changes the frequency of the alarm sound.

  The invention of claim 4 is characterized in that, in the invention of claim 1, the control unit continuously changes the frequency of the alarm sound in a predetermined frequency band.

It is characterized by.

The invention according to claim 6 is the invention according to any one of claims 1 to 5, wherein the control unit changes the frequency and volume of the alarm sound output from each sound output unit over time. .

The invention of claim 8 is characterized in that, in the invention of claim 7 , the control unit changes the volume of the alarm sound temporally and changes the light output of the light source unit in synchronization with the volume change of the alarm sound. And

According to the first aspect of the present invention, when the sensor unit detects the presence of a person in the detection area and outputs human body detection information, the control unit outputs an alarm sound from the sound output unit, and the frequency of the alarm sound is set. Because it changes over time, even if there is environmental noise in the surroundings, it is difficult to mask the alarm sound due to the environmental noise, and it is possible to realize a crime prevention device that is easier to hear than when the frequency of the alarm sound is constant If the frequency of the warning sound is constant and the level of ease of hearing is the same, the volume of the warning sound can be reduced by the amount that is easier to hear by changing the frequency over time. It is possible to realize a crime prevention device that outputs an alarm sound of a volume and prevents inconvenience to neighboring residents. Furthermore, the control unit increases the volume of the alarm sound as the frequency of the alarm sound is low. Generally, the ambient environmental noise contains a lot of low-frequency noise, and the deterioration of the hearing due to aging is an auditory perception of the high sound range. As the frequency of the alarm sound is lower, the volume of the alarm sound is increased so that the alarm sound can be heard more easily even when there is ambient environmental noise or when hearing is weakening due to aging. Can be realized. Furthermore, since a plurality of sound output units output alarm sounds having different frequencies and / or volumes, the source of the alarm sound moves to a person who has entered the detection area. A security device that can generate an illusion of sound and make it difficult to specify the position of the sound output unit, and can confuse the person and give them a sense of anxiety, thereby enhancing the crime prevention effect.

By changing the frequency and volume according to the change, it is possible to realize a crime prevention device that makes it easier to hear the alarm sound.

According to invention of Claim 6 , the control part raises the acoustic effect which makes it difficult to pinpoint the position of a sound output part by changing the frequency and volume of an alarm sound which are output from each sound output part each time. Security equipment can be realized.

According to the invention of claim 7 , when the human body detection information is input, the control unit outputs an alarm sound from the sound output unit, turns on the light source unit, and changes the light output with time. Therefore, it is possible to realize an illuminating device that can emit an alarm with light from the light source unit in addition to the alarm sound, and also uses a light source for emitting an alarm with light as a light source for illumination.

In addition, by synchronizing the change in the frequency of the alarm sound and the change in the light output of the light source unit, it is possible to realize a lighting fixture that enhances the effect of the alarm using both sound and light.

According to invention of Claim 8 , the lighting fixture which heightened the effect of the alarm by both a sound and light is realizable by synchronizing the volume change of an alarm sound and the change of the light output of a light source part.

  Embodiments of the present invention will be described below with reference to the drawings.

(Basic configuration)
The basic structure of the lighting fixture to which the crime prevention device according to the present invention is applied will be described with reference to FIGS. As shown in FIG. 1 (a), the luminaire A is a human sensor unit 2 including a pyroelectric infrared sensor that detects the presence or absence of a person by detecting a heat ray radiated from a human body in a predetermined detection area. A brightness sensor unit 3 made of CdS or a photodiode for detecting ambient brightness, a light source unit 4 for illuminating within a predetermined illumination area, and a sound output unit for outputting alarm sounds for threats and warnings 5, a remote control receiving unit 6 for receiving a remote control signal for switching the operation mode transmitted as a wireless signal composed of an optical signal such as an infrared ray from the remote control transmitter B, and various settings related to the operation (detection duration described later) For example, a control unit 1 that includes a microcomputer and controls the operation of each unit. Here, in this lighting fixture , when a person in the detection area is detected, a human sensor unit 2 that outputs human body detection information and a brightness sensor unit 3 that detects ambient brightness (illuminance) and outputs illuminance information. A sensor unit is configured to detect surrounding environment information including human body detection information (that is, human body detection information and illuminance information).

  The luminaire A is installed on an outdoor outer wall or a garden. In the case of a pouch light type as shown in FIG. 2A, a translucent translucent member 31 is provided on three surfaces and a lower surface. The light source unit 4 is housed inside the instrument main body 30 in which is fitted, and the instrument main body 30 is installed on the outer wall near the entrance via the flange part 32. The human sensor unit 2, the brightness sensor unit 3, and the remote control receiving unit 6 are exposed, for example, below the flange unit 32, and the control unit 1 and the setting unit 7 are housed inside the flange unit 32. The lighting fixture A is not limited to the shape described above, but may be a spotlight type as shown in FIG. This luminaire A includes a base portion 33 attached to the outer wall of a building, and a lamp 35 attached to the base portion 33 via an arm 34 so as to freely swing. The lamp 35 includes a cylindrical shade 36 in which the light source unit 4 is disposed, and the light of the light source unit 4 can be emitted as spot light by directing the lamp 35 in a desired direction. Here, the human sensor unit 2, the brightness sensor unit 3, and the remote control receiving unit 6 are exposed, for example, below the base unit 33, and the control unit 1 and the setting unit 7 are housed inside the base unit 33. . The lighting fixture A may be a pole type as shown in FIG. In this lighting fixture A, an opening window is provided on the upper peripheral surface of a columnar fixture body 37 installed on the ground, a translucent translucent member 38 is attached to the opening window, and an opening window is provided inside the fixture body 37. The light source unit 4 is accommodated so as to face it. The human sensor unit 2, the brightness sensor unit 3, and the remote control receiving unit 6 are exposed on the peripheral surface of the instrument body 37, for example, and the control unit 1 and the setting unit 7 are accommodated inside the instrument body 37. .

  On the other hand, as shown in FIG. 1B, the remote control transmitter B sets the operation mode of the lighting fixture A to the crime prevention mode (when the human sensor unit 2 detects a person, the light source unit 4 blinks and the sound output unit 5 emits a sound. Crime prevention mode selection switch 21 for switching to a mode that is intimidated by outputting) and an operation mode to a normal mode (a mode in which the light source unit 4 is turned on when the human sensor unit 2 detects a person to illuminate the illumination area) A normal mode selection switch 22 for switching, a continuous lighting selection switch 23 for continuously lighting the light source unit 4, a remote control transmission unit 24 for transmitting a remote control signal for switching the operation mode by a wireless signal, and each selection switch 21 The control unit 20 is configured to transmit a remote control signal corresponding to the operation from the remote control transmission unit 24 to the luminaire A when -23 is operated. FIG. 3 is an external view of the remote control transmitter B. The above-described crime prevention mode selection switch 21 and normal mode selection switch 22 are provided on the surface of a remote control main body 25 made of a resin molded product formed to a size that can be grasped by hand. The operation buttons 21a, 22a, and 23a of the continuous lighting selection switch 23 are arranged side by side. Thus, when one of the operation buttons 21a, 22a, and 23a is pressed, a remote control signal corresponding to the operation is transmitted from the remote control transmitter B to the luminaire A.

  Next, when the operation button 21a of the crime prevention mode selection switch 21 provided in the remote control transmitter B is pressed, a remote control signal for switching the operation mode to the crime prevention mode is transmitted from the remote control transmitter B to the lighting fixture A. The operation of the lighting fixture when the operation mode of the lighting fixture A is set to the crime prevention mode according to the remote control signal will be described based on the time chart of FIG.

  When the ambient brightness detected by the brightness sensor unit 3 is brighter than a predetermined threshold level, the control unit 1 does not turn on the light source unit 4 even if the human body detection information is input from the human sensor unit 2, and the sound No sound for intimidation or warning is output from the output unit 5. On the other hand, when the ambient brightness detected by the brightness sensor unit 3 becomes darker than a predetermined threshold level, the control unit 1 turns on the light source unit 4 to illuminate a predetermined illumination area. When the light source is composed of an incandescent lamp, the light source unit 4 is dimmed (see FIG. 4B), and when the light source unit 4 is composed of a fluorescent lamp such as an electrodeless discharge lamp, the light source unit 4 is fully lit. (See FIG. 4C).

  Then, when the ambient sensor detected by the brightness sensor unit 3 is darker than a predetermined threshold level and the person sensor unit 2 detects a person in the detection area as shown in FIG. t1) When the light source unit 4 is an incandescent lamp, the control unit 1 turns on the light source unit 4 based on the human body detection information from the human sensor unit 2 to illuminate the inside of the illumination area. When the person stays for a relatively long time, that is, when the human sensor unit 2 continuously outputs the human body detection information for the detection duration time (for example, 10 seconds) set by the setting unit 7, the control unit 1 displays the time t1. From the time t2 when the detection duration time elapses, the sound output unit 5 outputs two sounds of different frequencies (for example, 4 kHz and 2 kHz sounds) at a substantially constant volume (for example, 45 dB) for a predetermined time (for example, 10 seconds). Alternately By force, it emits a warning sound such as "Pipopipopipopipo ..." (see FIG. 4 (d)). Further, simultaneously with the output of the output sound, the control unit 1 switches on / off the light source unit 4 in synchronization with the frequency change of the output sound, and blinks the light source unit 4 for a predetermined time (FIG. 4B). (Refer to (c)), while threatening a person who has entered the detection area with both light and sound, it also gives warnings to householders, nearby residents and passers-by. The control unit 1 blinks the light source unit 4 when an alarm sound is output, but the light output of the light source unit 4 is set to, for example, a fully lit state and a dimming state in synchronization with the timing for switching the frequency of the alarm sound. By switching to, the light output may be changed with time.

  The control unit 1 includes a timer that limits a predetermined lighting holding time. When the blinking operation of the light source unit 4 is finished, the light source unit 4 is turned on again in a fully lighting state, and the lighting holding time of the timer is set. When the time limit operation is started and the timer expires, when the light source unit 4 is an incandescent lamp, the lighting output is switched from the full lighting state to the dimming lighting state. When the human body detection information is input again from the human sensor unit 2 during the time limit of the timer, the control unit 1 resets the timer and starts the timed operation of the lighting holding time again when the input of the human body detection information is stopped. (Retriggerable function), extending the lighting period in all lighting states.

Thus, in this lighting fixture , when the human sensor unit 2 detects a person who stays in the detection area for a predetermined detection duration or longer, the sound output unit 5 alternately outputs two types of sounds having different frequencies. By alternately outputting high and low frequency sounds, the alarm sound is less likely to be buried in the surrounding environmental noise compared to the case where one single sound is output. In addition, the alarm sound is easy to hear for the householder, neighboring residents, and passers-by, and it is also easy for the elderly with a weak hearing function. Therefore, if the sound output unit 5 outputs one type of single sound and the ease of hearing is the same, the volume of the alarm sound can be reduced compared to the case where one type of single sound is output. Even if many false alarms occur due to the use of a simple sensor consisting of pyroelectric infrared detectors in the sensor unit 2, it is possible to reduce the volume of the output sound and not be surprised by distant residents and passers-by. The neighborhood will not be annoying.

In this lighting fixture , the control unit 1 alternately switches the frequency of the output sound from the sound output unit 5 to two types of frequencies. However, a plurality of (three or more types) output sounds having different frequencies are prepared. The output sound selected alternatively from the output sounds may be output from the sound output unit 5, so that the frequency of the alarm sound may be temporally changed. For example, a plurality of output sounds are repeated in a predetermined order. The frequency of the warning sound may be changed periodically by outputting, or the frequency of the warning sound can be changed randomly by sequentially outputting the output sound randomly selected from a plurality of output sounds. Alternatively, when switching the frequency of the output sound, the sound output may be stopped for a short time to output the sound intermittently.

  In this embodiment, the operation mode is switched in response to a remote control signal from the remote control transmitter B. However, the means for switching the operation mode is not limited to the remote control transmitter B, and is provided indoors, for example. The operation mode may be switched by operating the switch, or the operation mode switching means may be omitted, and the crime prevention mode may be automatically switched according to, for example, the time zone or surrounding light / darkness.

Moreover, in this lighting fixture , based on the human body detection information of the human sensor unit 2 only when the ambient brightness detected by the brightness sensor unit 3 becomes darker than a predetermined threshold level in the state where the crime prevention mode is set. While the alarm output is output from the sound output unit 5 and the light source unit 4 is blinked, if the crime prevention mode is set, it is based on the human body detection information of the human sensor unit 2 regardless of the surrounding brightness. While outputting an alarm sound from the sound output unit 5, the light source unit 4 may be blinked.

Next, the other form of the lighting fixture A is demonstrated based on FIG. In addition, the same code | symbol is attached | subjected to the component which is common in the above-mentioned lighting fixture A, and the description is abbreviate | omitted.

In the lighting fixture A described in the basic configuration, when the ambient brightness detected by the brightness sensor unit 3 becomes darker than the threshold level during operation in the crime prevention mode, the human sensor unit 2 detects a predetermined detection duration or longer. When the human body detection information is continuously input, the control unit 1 alternately outputs two kinds of sounds having different frequencies from the sound output unit 5, whereas in the present lighting device , as shown in FIG. The frequency of the output sound is continuously changed from 1 kHz to 20 kHz during a predetermined period Tc, and when the frequency reaches 20 kHz, the frequency is returned to 1 kHz again and continuously changed from 1 kHz to 20 kHz. By repeating the change, for example, an alarm sound such as “Huien Huyen” is generated, and by continuously changing the frequency, the lighting apparatus described in the basic configuration Similarly, without being buried in the surrounding environmental noise, the suspicious person can be surely heard the warning sound, and the warning sound can be easily heard by the householder and neighboring residents.

In this lighting fixture , the control unit 1 continuously changes the frequency of the output sound from the sound output unit 5 in the frequency region from 1 kHz to 20 kHz. The region where the frequency is changed is the frequency region described above. The frequency of the output sound may be continuously changed in a frequency range appropriately set according to the use environment. Further, in this lighting apparatus , the control unit 1 gradually increases the frequency of the output sound in a predetermined frequency range, but may be gradually decreased in the predetermined frequency range, or may be random (randomly) in the predetermined frequency range. ) May be changed in frequency.

(Embodiment 1 )
The first embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the component which is common in the lighting fixture A demonstrated by the basic composition, and the description is abbreviate | omitted.

In the lighting fixture A described in the basic configuration, when the ambient brightness detected by the brightness sensor unit 3 becomes darker than the threshold level during operation in the crime prevention mode, the human sensor unit 2 detects a predetermined detection duration or longer. When the human body detection information is continuously input, the control unit 1 alternately outputs two types of sounds having different frequencies from the sound output unit 5, and sets the volume levels of these two types of sounds to substantially the same level. In contrast, in the present embodiment, when two types of sounds (4 kHz and 2 kHz sounds) are alternately output, the lower frequency sound (2 kHz) is changed to the higher sound level (4 kHz) ( For example, it is output at a volume (for example, 60 dB) larger than 30 dB (see FIG. 6).

  In general, environmental noise in residential areas and the like contains a lot of low-frequency noise, so that the lower the frequency, the more susceptible to environmental noise. In general, elderly people tend to lose their hearing. Especially, since the auditory deterioration is particularly remarkable with respect to high-frequency sounds, it is preferable to increase the low-frequency sounds. In the present embodiment, when two kinds of sounds are output from the sound output unit 5, the volume of the sound with the lower frequency is made larger than the volume of the sound with the higher frequency, so even if there is environmental noise. This makes it easier to hear low-frequency sounds, and makes it easier for people with low-frequency hearing.

  In this embodiment, the control unit 1 alternately switches the output sound from the sound output unit 5 to a 2 kHz sound and a 4 kHz sound, the 2 kHz sound is a sound pressure of 60 dB, and the 4 kHz sound is a sound pressure of 30 dB. Although the output is performed, the setting of the frequency and volume is not limited to the above setting, and may be set as appropriate according to the ambient environmental noise and usage. Further, the control unit 1 may prepare a plurality of (three or more types) frequencies as the frequency of the output sound, and output the plurality of types of output sound in a predetermined order or randomly. The volume level may be changed according to the frequency so that the volume level is increased as the sound becomes lower. Further, in the control unit 1, the volume level is changed according to the frequency so that the volume level increases toward the low frequency side, but may be changed so that the volume level increases toward the high frequency side.

The control unit 1 blinks the light source unit 4 by turning on or off the light source unit 4 in synchronization with the timing of switching the sound volume when outputting the alarm sound as described in the lighting fixture A having the basic configuration . In synchronism with the timing of switching the volume of the alarm sound, the light output may be temporally changed by switching the light output of the light source unit 4 between, for example, a fully lit state and a dimming state.

Another embodiment of the lighting apparatus according to the present invention will be described with reference to FIGS. In this lighting fixture A , the remote control receiving unit 6 is not provided in the lighting fixture described in the basic configuration, and the operation mode is set by the setting unit 7, and other configurations are the same as the lighting fixture described in the basic configuration. Since it is the same, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

This lighting fixture is a simple residential security appliance, but in a residential area, the ambient noise is extremely low at night when the surroundings are dark. Environmental noise tends to increase. Therefore, if the volume of the alarm sound output from the sound output unit 5 is set to a level that is just good in accordance with the nighttime noise level, it becomes difficult to hear in the daytime and just good to match the noise level in the daytime. If the volume is set, it will be heard at night as loud noise that may cause inconvenience in the neighborhood.

Therefore, in this lighting fixture , when the control unit 1 outputs sound from the sound output unit 5 based on the human body detection information from the human sensor unit 2, the illuminance information (environment information) detected by the brightness sensor unit 3 is used. The volume level is changed accordingly, and when the surrounding brightness is brighter than a predetermined threshold level, the volume level is set larger than when the brightness is darker than the threshold level.

  That is, as shown in FIG. 7, when the ambient brightness (illuminance) detected by the brightness sensor unit 3 is darker than the predetermined threshold level L1, the human sensor unit 2 detects a person in the detection area, When the human body detection information is continuously output for a predetermined detection duration (for example, 10 seconds) or longer, the control unit 1 substantially omits the sound output unit 5 from the sound output unit 5 for a predetermined time from the time t4 when the detection duration has elapsed from the time t3. Two sounds with different frequencies (for example, 4 kHz and 2 kHz sounds) are output alternately at a constant volume (for example, 40 dB), and an alarm sound such as “pippi pipopipipo ...” is generated. The control unit 1 blinks the light source unit 4 for a predetermined time in synchronism with the frequency change of the output sound simultaneously with the output of the output sound, and threatens a person who has entered the detection area with both light and sound. At the same time, warnings are given to householders and neighbors.

  On the other hand, as shown in FIG. 8, when the surrounding brightness (illuminance) detected by the brightness sensor unit 3 is brighter than a predetermined threshold level L1, the human sensor unit 2 detects a person in the detection area, When the human body detection information is output continuously for a predetermined detection duration or longer, the control unit 1 is more than the case where the ambient illuminance is darker than the threshold level L1 for a predetermined time from time t6 when the detection duration time has elapsed from time t5. Two sounds with different frequencies (for example, 4 kHz and 2 kHz) having a large substantially constant volume (for example, 70 dB) are alternately output from the sound output unit 5 to generate an alarm sound such as “pippi pipopipipo ...”. The control unit 1 blinks the light source unit 4 for a predetermined time in synchronism with the frequency change of the output sound simultaneously with the output of the output sound, and threatens a person who has entered the detection area with both light and sound. At the same time, warnings are given to householders and neighbors.

In this way, the volume of the two types of output sounds from the sound output unit 5 is switched between two types, large and small, according to the brightness of the ambient illuminance detected by the brightness sensor unit 3 and the threshold level L1. During the daytime when there is a large amount of noise, the volume of the alarm sound can be increased to prevent the sound of the alarm sound from becoming difficult to hear due to the environmental noise. I am surprised by the fact that my neighbor is annoying. In this lighting fixture , the control unit 1 changes only the volume of the alarm sound according to environmental information (illuminance information detected by the brightness sensor unit 3) other than the human body detection information. May be changed, or only the frequency may be changed.

In this lighting fixture , the control unit 1 alternately switches the output sound from the sound output unit 5 between a 2 kHz sound and a 4 kHz sound, the output sound volume is set to 70 dB during the day, and the output sound volume is set to 40 dB at night. However, the setting of the frequency and volume is not limited to the above setting, and may be set as appropriate according to the ambient environmental noise and usage. In addition, the control unit 1 may prepare a plurality of (three or more types) frequencies as output sound frequencies, and may output the plurality of types of output sounds in a predetermined order or randomly. The detection duration time 2 may be set as appropriate in accordance with the use situation.

Embodiment of the lighting fixture which concerns on this invention is described based on FIGS. 9-13. FIG. 9 is a block diagram of the luminaire. In the luminaire A, the remote control receiver 6 is eliminated from the luminaire described in the basic configuration, the operation mode is set by the setting unit 7, and threats and warnings are displayed. There are provided two sound output units (first sound output unit 5a and second sound output unit 5b) for outputting the sound for each. In addition, since the structure other than that is the same as that of Embodiment 1, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

FIG. 10 (a) is an external perspective view of the luminaire , and FIG. 10 (b) is a front view. The luminaire A comprises a direct-attached type pouch light, and is a cylindrical fixture body that is directly attached to a wall surface. 39, a translucent dome-shaped translucent member 40 is attached to the front opening of the instrument body 39, and the light source unit 4 is accommodated inside the instrument body 39 so as to face the translucent member 40. is there. The first sound output unit 5a and the second sound output unit 5b are disposed on the left and right sides of the instrument body 39 with the instrument body 39 attached to the wall surface, and the human sensor is disposed on the lower side of the instrument body 39. The unit 2 and the brightness sensor unit 3 are attached.

  Next, operation | movement of this lighting fixture A is demonstrated based on the time chart shown in FIG. In a state where the ambient brightness (illuminance) detected by the brightness sensor unit 3 is darker than a predetermined threshold level, the human sensor unit 2 detects a person in the detection area at time t7, and the predetermined detection duration ( When the human body detection information is output continuously for 10 seconds or more, for example, the controller 1 outputs the first sound output unit 5a and the second sound output unit for a predetermined time from the time t8 when the detection duration time has elapsed from the time t7. 5b outputs sounds with different volumes, changes the frequency of each output sound with time, and blinks the light source unit 4 for a predetermined time in synchronization with the change in frequency of the output sound. The sound threatens the person who has entered the detection area with both sounds, and at the same time alerts the householder, nearby residents and passers-by.

  Here, FIG. 12A is an explanatory diagram of an output sound from the first sound output unit 5a, FIG. 12B is an explanatory diagram of an output sound from the second sound output unit 5b, and the control unit 1 Two types of sounds having different frequencies (for example, 4 kHz and 2 kHz sounds) are alternately output from the first sound output unit 5a and the second sound output unit 5b at predetermined time intervals. At this time, the control unit 1 outputs the 4 kHz sound from the second sound output unit 5b in synchronization with the period Ta during which the 4 kHz sound is output from the first sound output unit 5a, and the 2 kHz sound from the first sound output unit 5a. The 2 kHz sound is output from the second sound output unit 5b in synchronization with the period Tb during which the sound is output, and the output sound from the first sound output unit 5a is 2 kHz compared to the volume V1 of the 4 kHz sound. The volume V2 is increased to output an alarm sound that sounds like "(pi) po (pi) po (pi) po (pi) po ...", and the output sound from the second sound output unit 5b is 4 kHz. The sound volume V1 of 2 kHz is made smaller than the sound volume V2, and an alarm sound that sounds like “pi (pi) pi (po) pi (po)...” Is output. Note that “” indicates a tone color of a warning sound, a sound surrounded by () indicates a sound with a low volume, and a sound not surrounded by () indicates a sound with a high volume (hereinafter the same).

Thus, in this lighting fixture , while changing the frequency of the sound output from two sound output parts (the 1st sound output part 5a and the 2nd sound output part 5b) periodically at the same timing, the 1st sound output part Since the volume levels of the output sound from 5a and the output sound from the second sound output unit 5b are different from each other, a warning sound source (the first sound source for the suspicious person who entered the detection area of the human sensor unit 2) The first sound output unit 5a and the second sound output unit 5b) can cause an illusion that they are moving, and can generate an acoustic effect that makes it difficult to specify the position of the sound source. By confusion and anxiety, the effect of giving up intrusion into the house can be obtained.

In this lighting fixture , the volume of 2 kHz sound and 4 kHz sound output from the first sound output unit 5 a are constant, and the volume of 2 kHz sound output from the second sound output unit 5 b and 4 kHz. The volume of the output sound may be set appropriately according to the usage environment. For example, as shown in FIG. 13, the volume of the 4 kHz sound output from the first sound output unit 5a is set. As the time passes, V3, V4, V5, V6, etc. are increased stepwise, and the volume of the 2 kHz sound is gradually reduced as time passes, such as V6 ′, V5 ′, V4 ′, V3 ′, and so on. The volume of the 4 kHz sound output from the second sound output unit 5b is gradually reduced to V6, V5, V4, V3,... Over time, and the volume of the 2 kHz sound is decreased to V3 ′, V4 with time. ', V5' , V6 ′... Further, the frequency of the output sound output from the first sound output unit 5a and the second sound output unit 5b may be set as appropriate according to the use environment, and the frequency of the output sound is switched alternately between two types of frequencies. A plurality of (three or more) frequencies are prepared as the frequency of the output sound, and the plurality of types of output sound are periodically switched in a predetermined order, and the volume of the sound of each frequency is set between the plurality of sound output units. You may make it mutually differ.

Further, in this lighting fixture , the volume of the sound output from the plurality of sound output units is different from each other, but the volume is substantially the same, the frequencies are different from each other, and the frequency or volume of the output sound is temporally changed. It may be changed, and an acoustic effect that makes it difficult to understand the position of the output sound generation source can be obtained in the same manner as described above.

In the above description, the lighting device with the crime prevention function using the crime prevention device according to the present invention has been described as an example. However, by eliminating the light source unit 4 from each lighting device, the crime prevention device having no light source unit. The control unit 1 outputs only an alarm sound from the sound output unit 5 based on the human body detection information from the human sensor unit 2, and the frequency of the alarm sound is temporally determined according to the method described in each embodiment.
