Description

  The present invention relates to an illuminating device that functions as normal illumination and crime prevention illumination based on detection signals from a moving body sensor and an illuminance sensor.

2. Description of the Related Art Conventionally, lighting devices having functions of normal lighting and crime prevention threatening illumination are known (see, for example, Patent Document 1).
In the lighting device described in Patent Document 1, the human sensor unit detects a person, and the brightness sensor unit detects ambient brightness. When the brightness sensor unit detects that the surroundings are bright and the human sensor unit detects a person, the alarm buzzer reports a threatening buzzer for a certain period of time. On the other hand, when the brightness sensor unit detects that the surroundings are dark, when the human sensor unit detects a person, the lighting is turned on and flashing (flashing) for intimidation is performed for a certain period of time.
In addition, when the human sensor unit detects a person again within a predetermined time from the previous report, another type of report different from the previous report is performed. That is, when the previous report is a light report, the next report is issued by a buzzer.
JP 2005-275861 A

  However, in the conventional lighting device, when the surroundings are judged to be bright, a buzzer is used for alarming, and when the surroundings are judged to be dark, the lighting is used for notification so that a person is detected. There was a problem that there was a case where it would always be informed and sometimes threaten people unnecessarily.

  The present invention was made in order to solve the conventional problem, and when a moving object is detected, it is surely threatened when it is judged as a criminal purpose, and even when a moving object is detected, an animal other than a human being If the purpose is not a criminal purpose, an object is to provide a lighting device capable of suppressing a threatening action.

  The illumination device of the present invention includes a light emitting unit that emits light, a sounding unit that emits an alarm sound, a moving body sensor that detects a moving body within a predetermined range, an illuminance sensor that detects brightness around an installation location, and the light emitting unit. And a control unit that controls the sound generation unit, wherein the control unit detects that the illuminance sensor is bright based on detection signals from the moving body sensor and the illuminance sensor. When the moving body sensor continues to detect the moving body for a certain period of time, the light emitting unit is turned on or blinking for a certain period of time, the sounding unit is operated to emit an alarm sound for a certain period of time, and the illuminance sensor is dark. In the case of detection, if the moving body sensor continues to detect the moving body for a certain period of time, the light emitting unit is turned on or blinked for a certain period of time, and the moving body sensor continues for a certain period of time or longer. When detecting a moving object Te is characterized in that to emit the controls the sound generator a light emitting portion causes a certain time lighting or flashing a warning sound certain time.

  With this configuration, when it is detected that the illuminance sensor is bright, if the moving body sensor continues to detect the moving body for a certain period of time, it is determined that the probability that the moving body is a person is high, and the light emitting unit is turned on for a certain period of time. Since the alarm sound is generated for a certain period of time by turning on or flashing and generating a sound generation unit, it is possible to reliably threaten a suspicious person even during bright daytime. When the illuminance sensor detects that the moving body is dark, if the moving body sensor continues to detect the moving body for a certain period of time, it is determined that the moving body is a person, and the light emitting unit is turned on or blinked for a certain period of time. When the sensor detects a moving object continuously for a certain time or more, it is judged that there is a high probability of leading to a crime, and the light emitting part is turned on or blinking for a certain time and the sounding part is controlled to emit a warning sound for a certain time. In addition to preventing excessive threats against moving objects that are not considered criminal purposes, it is possible to reliably threaten criminal purposes.

  Moreover, in the illuminating device of this invention, it has the structure which adjusts the volume of the said sound production | generation part according to the signal from the said illumination intensity sensor.

  With this configuration, the volume of the alarm sound can be adjusted in accordance with the ambient brightness. For example, at night, the volume of the alarm sound can be reduced so as not to disturb the neighborhood.

  Furthermore, the lighting device of the present invention has a configuration in which the sound volume generated by the sound generation unit is increased as the time for the moving body sensor to detect the moving body becomes longer.

  With this configuration, if the time during which a moving object is detected becomes longer, it is judged that the probability of being a crime is high, the alarm sound is increased, the threatening effect is increased, and the existence of a suspicious person is surely notified to the surroundings. it can.

  In the present invention, when it is detected that the illuminance sensor is bright and the moving body sensor continues to detect the moving body for a certain period of time, it is determined that the probability that the moving body is a person is high, and the light emitting unit is turned on for a certain period of time. Since the alarm sound is generated for a certain period of time by turning on or flashing and generating a sound generation unit, it is possible to reliably threaten a suspicious person even during bright daytime. When the illuminance sensor detects that the moving body is dark, if the moving body sensor continues to detect the moving body for a certain period of time, it is determined that the moving body is a person, and the light emitting unit is turned on or blinked for a certain period of time. When the sensor detects a moving object continuously for a certain time or more, it is judged that there is a high probability of leading to a crime, and the light emitting part is turned on or blinking for a certain time and the sounding part is controlled to emit a warning sound for a certain time. In addition to preventing excessive threats against moving objects that are not considered criminal purposes, they can reliably threaten criminal purposes.

FIG. 12 is a flowchart showing the operation function, FIG. 12 is a flowchart showing the return after the power is turned off, and FIG. 13 is a time chart showing the mode change when the power is turned on.

  As shown in FIG. 1, a lighting device 10 according to the present invention includes a lighting fixture body 20 that is fixed to a wall 11 with screws or the like, and a cover made of translucent resin or glass that covers the front surface of the lighting fixture body 20. 21. A socket 22 is attached inside the luminaire main body 20, and a lamp 23, which is a light emitting unit, is attached in a replaceable manner. The socket 22 is connected to the commercial AC power supply 12 via the control unit 24. . In addition, a buzzer 27 as a sound generation unit is provided at the lower part of the lighting fixture body 20 and is connected to the control unit 24.

  Further, a detection unit 26 having a moving body sensor 26a for detecting a moving body moving within a set detection range based on a temperature change and an illuminance sensor 26b for detecting ambient brightness is attached to the lower end surface of the lighting fixture body 20. It is exposed to the outside of the luminaire main body 20 from the notch 21a on the lower surface of the cover 21 and can be detected. As shown in FIG. 2, the detection unit 26 can change the detection range in the front-rear direction and the left-right direction. In addition, a remote control light receiving unit 28 is provided in the vicinity of the detection unit 26 and is exposed to the outside of the luminaire main body 20 from the notch 21a of the cover 21 so that signal light from the remote control can be received.

  As shown in FIG. 3, the control unit 24 is connected to an external commercial AC power supply 12 (for example, an outlet in the back), and the power is supplied through a power switch 13 provided on the wall in the back. Have been supplied. A moving body sensor 26 a and an illuminance sensor 26 b are connected to the control unit 24, and send detection signals to the control unit 24, respectively. In the control unit 24, the lamp 23 is turned on and a buzzer 27 emits an alarm sound according to each mode to be described later based on signals from the sensors 26 a and 26 b.

  As shown in FIG. 4, the adjustment knob 25 is provided with a lighting holding time adjusting knob 25a, a brightness sensor adjusting knob 25b, a welcome time adjusting knob 25c, and the like. Adjustable. FIG. 4 is an example, and various switches can be increased or decreased as necessary.

  As shown in FIG. 5, the remote control 40 is provided with an outing security mode switch 41, a normal security mode switch 42, a continuous lighting switch 43, a volume adjustment switch 44, and the like. Therefore, a signal can be sent to the control unit 24 by pressing the switches 41 to 44 with the signal light emitting unit 45 directed toward the remote control light receiving unit 28 of the lighting fixture body 20. Note that FIG. 5 is an example, and various switches can be increased or decreased as necessary.

Next, each mode of the illumination device 10 will be described.
<Continuous lighting mode>
Regardless of the detection of the moving body sensor 26a and the illuminance sensor 26b, the lighting continues at 100% brightness. This can be set by pressing the continuous lighting switch 43 of the remote controller 40 described above.

<Normal mode (greeting mode)>
When the control unit 24 determines that the illuminance (brightness) exceeds a certain level within the detection range based on the detection signal sent from the illuminance sensor 26b, the control unit 24 turns on the lamp 23 and the buzzer 27. Do not order pronunciation.

  On the other hand, after the control unit 24 determines that the surrounding is dark based on the detection signal from the illuminance sensor 26b, the lamp 23 is turned off or slightly lit (for example, 20%) when the synchronous sensor 26a does not detect a moving object. Lit at the brightness of. When the moving body sensor 26a detects a moving body within the detection range, the lamp 23 is turned on with welcome brightness (for example, 100%), and the buzzer 27 does not sound. When the moving body sensor 26a no longer detects a moving body, it is turned on for a predetermined lighting holding time and then turned off or slightly turned on.

  Note that the lighting holding time can be set in advance from 5 seconds to 3 minutes, for example, using the adjustment knob 25a (see FIG. 4) provided in the lighting fixture body 20. The welcome brightness can be adjusted by the brightness sensor adjustment knob 25b. Furthermore, the time for functioning the welcome mode can be adjusted from zero (off) to morning by the welcome time adjustment knob 25c.

In this way, when the moving object (person) approaches, the lamp 23 is turned on without threatening from the meaning of greeting, so it can be said that it is a greeting mode.
When the transition from day to night is detected by the detection signal from the illuminance sensor 26b, the control unit 24 turns on the lamp 23 for a certain period of time using a built-in timer, After the light is turned off, it may be turned on when the moving body sensor 26a detects a moving body.

<Security mode>
(1) Outing Security Mode As shown in FIG. 6, in the outing security mode, the security mode functions in the daytime when the illuminance sensor 26b detects that it is bright and in the nighttime when it is detected as dark.

A, Daytime As shown in FIG. 6 (A), when the illuminance sensor 26b detects that the light is bright, the moving body sensor 26a continues to detect the moving object for a certain period of time (10 seconds in FIG. 6 (A)). In other words, the control unit 24 lights or blinks the lamp 23 for a certain time (10 seconds in FIG. 6) and emits an alarm sound using the buzzer 27 for a certain time. In FIG. 6, for example, when the moving body sensor 26a detects, for example, 10 seconds after detecting a person, the lighting and alarm are issued, but this is simply an animal when it is detected for a short time within a certain time. Since the car may have crossed, the lamp 23 is turned on and an alarm is given by the buzzer 27 when it is determined that the person is within the detection range for a certain time (10 seconds in this case).

B. As shown in FIG. 6B, when the illuminance sensor 26b detects that the illuminance sensor 26b is dark and the moving body sensor 26a does not detect the moving body, the control unit 24 turns on the lamp 23 with a brightness of 20%. After that, when a moving object is detected within the welcome time, the lamp 23 is turned on with 100% brightness because the probability of being a customer or the like is high. In this case, there is no threat from the buzzer 27. In addition, when the moving body sensor 26a continues to detect a moving body for a certain time or longer after the welcome time has elapsed, the control unit 24 lights or blinks the lamp 23 for a certain time, and the moving body sensor 26a remains on the certain time (in FIG. 6). When the moving object is detected for more than 20 seconds), the lamp 23 is turned on or blinks for a certain period of time and an alarm sound is emitted by the buzzer 27 for a certain period of time.

  In FIG. 6B, if the moving object sensor 26a detects a moving object, the lamp 23 is turned on (flashes) 10 seconds later, and if a moving object is detected after 10 seconds, the probability of being a crime A warning is issued as high. That is, 10 seconds after the lighting (flashing) of the lamp 23 is set to be 10 seconds as a time that can be prevented from being erroneously detected because it is shorter than the time required for intrusion at night in picking or the like.

  With this configuration, when it is detected that the illuminance sensor 26b is bright and the moving body sensor 26a continues to detect the moving body for a certain period of time, it is determined that the probability that the moving body is a person is high, and the lamp 23 is turned on. Since the buzzer 27 emits an alarm sound for a certain period of time while the light is turned on or blinking for a certain period of time, it is possible to reliably threaten a suspicious person even during bright daytime. When the illuminance sensor 26b detects that the moving body sensor 26a continues to detect the moving body for a certain period of time, it is determined that the moving body is a person and the lamp 23 is lit or blinked for a certain period of time. If the moving body sensor 26a continuously detects a moving body for a certain period of time, it is determined that there is a high probability of being a crime, and the lamp 23 is turned on or blinking for a certain period of time, and the buzzer 27 is controlled to emit an alarm sound for a certain period of time. Therefore, it is possible to prevent excessive threats against moving objects that are not intended for criminal purposes and to reliably threaten those who are criminal purposes.

In addition, as shown in FIG. 7, it is desirable that the control unit 24 adjusts the volume of the buzzer 27 in response to the signal from the illuminance sensor 26b.
Thereby, for example, the volume can be increased during the daytime when the surrounding noise is large, and the volume of the alarm sound can be decreased during quiet night so as not to disturb the neighborhood.

In addition, as shown in FIG. 8, it is desirable that the control unit increase the volume generated by the buzzer 27 as the time for the moving body sensor 26a to detect the moving body becomes longer. For example, in the case shown in FIG. 8, an alarm is initially generated at 1/3 the set value, and after 10 seconds, the alarm volume increases to the set value.
As a result, if the time during which a moving object is detected becomes longer, it is determined that the probability of being a crime is high, the alarm sound is increased, the threatening effect is increased, and the existence of a suspicious person can be reliably notified to the surroundings. .

(2) Normal security mode (security mode only at night)
As shown in FIG. 9, in the normal security mode, during the daytime when the illuminance sensor 28b detects that it is bright, the lighting of the lamp 23 and the alarm by the buzzer 27 are not performed regardless of the detection of the moving object. Then, after detecting that the illuminance sensor 28b is dark, the B. in the crime prevention mode (1) in the <crime prevention mode> described above. Acts the same as at night.

  This “normal security mode” can be forcibly turned off by turning off the security function. For example, if you know that the day's return will be late at night, when you go home late at night, you will be in the normal security mode. It may be turned off forcibly. In such a case, if you do not cancel the forced OFF of the “normal security mode”, the “normal security mode” will remain canceled the next night, and the security function can be performed properly. Can not. For this reason, in the case where the “normal security mode” is forcibly set to OFF, the “normal security mode” is automatically switched ON when it is determined that the illuminance sensor 26b is bright.

  As a result, when the illuminance sensor 26b detects that the surrounding area is bright the next morning, the “normal security mode” is automatically turned off and turned on, so the “normal security mode” is changed from OFF to ON. The trouble of switching can be saved, and the “normal crime prevention mode” can be surely turned on to properly perform the crime prevention function.

  In addition, there is a button switch that switches between the “going out crime prevention mode” ON state and the “normal security mode” ON state, and the “normal security mode” is forcibly turned off by pressing and holding this button switch. It is desirable to be able to. For example, the normal security mode is turned on by pressing the normal security mode switch 42 of the remote controller 40 shown in FIG. 5, but the normal security mode is turned OFF by pressing and holding the normal security mode switch 42 for a predetermined time or longer. .

  As a result, the “normal security mode” can be turned off by long-pressing the normal security mode switch 42 for switching between the “outgoing security mode” being ON and the “normal security mode” being ON. Even if the remote controller does not have a function of turning off the “normal security mode”, the “normal security mode” can be turned off. Further, the “normal security mode” can be turned off even when the remote control is not nearby.

<Test mode>
The test mode is not a mode for defining the function of the lighting device 10, but it is necessary to test the range of the object sensor 26 a and the lighting holding time when the lighting device 10 is installed. Also, when the detection range of the object sensor 26a is readjusted (see FIG. 2), it is necessary to perform a test after setting. In this case, this is a mode for performing an efficient test.

  In this test mode, the test lighting time by the lamp 23 is set to be less than the minimum lighting holding time (for example, 5 seconds) during use (for example, 3 seconds). At the same time, the brightness of the lamp 23 is set to “brighter” and the welcome time is set to “off”. Transition to the test mode can be easily performed by turning the brightness sensor adjustment knob 25b of the adjustment knob 25 described above with reference to FIG. 4 to the test position.

  Accordingly, when testing the range of the object sensor 26a, lighting holding time, and the like at the time of installation or after adjustment after installation, the test mode can be set with one operation of the switch 25b, so that the test can be easily performed. it can. In this case, since the lighting time can be set shorter than the normal lighting holding time, the next test can be performed in a short time, and the test can be performed efficiently.

In the test mode, it is desirable to issue an alarm by the buzzer 27 simultaneously with the lighting by the lamp 23.
As a result, a sound is emitted along with lighting during the test, so that the range of the object sensor 26a can be confirmed even in a bright place, and the buzzer 27 can be tested.

  Next, switching between the above modes will be described.

A. When using the remote control As described above with reference to FIG. 5, the remote control 40 is provided with the switches 41 and 42 for shifting to the respective modes. By pressing the switches 41 and 42, it is possible to shift to the desired mode. it can.
B. When using a power switch As shown in FIG. 10, generally, a mode different from the currently set mode can be obtained by continuously switching OFF / ON using the power switch 13 installed on the inner wall or the like. Switching can be set.

  In this way, by switching the power switch 13 OFF / ON continuously, it is possible to switch to a mode different from the currently set mode, so when the remote control 40 is lost or when the battery runs out, Mode switching can be easily performed without using the remote controller 40. In addition, since the mode is switched only when the power switch is continuously switched OFF / ON different from normal use, mode switching unintended by the user can be prevented.

When the power switch 13 is switched off in a normal use state, it is desirable to maintain the mode before switching off when the power switch 13 is turned on next time.
Thereby, even when the power switch is accidentally turned off or when there is a power failure, it is possible to easily return to the previous state.

  A specific example is shown in FIG. When power is turned on after installation (step SS), a stabilization standby state (step S1) is entered. A moving body sensor such as a pyroelectric element is provided with a stabilization standby state when the power is turned on because the sensor output becomes unstable when the power is turned on. In the stabilization standby state, the lamp 23 is turned on. If there is no continuous operation of the power switch 13 during this stabilization standby state (step S2), the process proceeds to the default crime prevention mode (step S3). The flag at this time is stored as F = 2 (step S4). Thereafter, when the power switch 13 is turned off, if the normal operation (step S5) is performed, the power is turned off while F = 2 is maintained (step S6). On the other hand, when a continuous operation is performed in step S5, the flag is set to F = 1 (step S7), and the process moves to the normal mode and is executed (step S8). If there is no operation of the power switch 13 in step S5, the security mode continues to be executed.

  As shown in FIG. 13A, when the power switch 13 is continuously operated in step S2 during the stabilization standby state, the default security mode is shifted to the normal mode (step S9), and the flag is set. Is stored as F = 1 (step S10), and the normal mode is executed. Then, the power switch 13 is operated (step S11), and when the power switch 13 is turned OFF by a normal operation, F = 1 is maintained and the process ends (step S12). On the other hand, when the power switch 13 is continuously operated in step S11, the flag is set to F = 2 (step S13), and the process proceeds to the crime prevention mode (step S14). If there is no operation of the power switch 13 in step S11, the normal mode continues to be executed.

  Next, when the power is turned off at steps S6 and S12 in FIG. 11, and when the power is turned off due to a power failure or the like during execution of each mode at steps S8 and S14, the power switch 13 is turned on next. Will be described.

  As shown in FIG. 12, when the power switch 13 is turned on (step S15), the flag is judged after the stabilization standby state (step S16) has elapsed (step S17). When the flag is F = 1, it is normal. The mode is executed (step S18). Thereafter, the power switch 13 is operated (step S19), and in the case of a normal operation, it is turned off (step S20). On the other hand, if the operation is continued in step S19, the flag is changed to F = 2 (step S21), and the crime prevention mode is executed (step S22).

  On the other hand, if it is determined in step S17 that F = 1 is not true, the security mode is executed (step S23). Thereafter, the power switch 13 is operated (step S24), and in the case of normal operation, the power switch 13 is turned off (step S25). On the other hand, when the operation is continuously performed in step S24, the flag is changed to F = 1 (step S26), and the normal mode is executed (step S27).

C. When nothing is done In the lighting device 10 having various modes, a mode to be used is selected as necessary. At that time, the remote control switch 40 is generally used. However, since the user does not shift to the crime prevention mode unless the user intentionally switches to the crime prevention mode, the user switches to the crime prevention mode when leaving the house. If you forget, the security function will not work. For this reason, when the moving body sensor 26a does not detect a moving body for a certain period of time (for example, 24 hours), the security mode is set to intimidate the moving body.

  As a result, even when switching to the crime prevention mode is forgotten, the crime prevention function can be surely activated. If no person is detected from 7:00 to 17:00, the system automatically shifts to the “go-out security mode”, and automatically shifts to the “normal security mode” at 7:00 (after 14 hours) the next day. With this setting, if no person is detected in the daytime, it is possible to shift to the “go-out security mode” at night.

  Moreover, it is desirable to maintain the crime prevention mode until the release by the release means. As the release means, the switches 41 and 42 of the remote controller 40 can be used. Alternatively, it can be canceled by continuous operation of the power switch 13.

  In addition, the illuminating device of this invention is not limited to each embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.

  As described above, when the illumination device according to the present invention detects that the illuminance sensor is bright and the moving body sensor continues to detect the moving body for a certain period of time, it is determined that the probability that the moving body is a person is high. In addition, since the light emitting unit is turned on or blinking for a certain period of time and the sounding unit is activated to emit an alarm sound for a certain period of time, it is possible to reliably threaten a suspicious person even during bright daytime. When the illuminance sensor detects that the moving body is dark, if the moving body sensor continues to detect the moving body for a certain period of time, it is determined that the moving body is a person, and the light emitting unit is turned on or blinked for a certain period of time. When the sensor detects a moving object continuously for a certain time or more, it is judged that there is a high probability of leading to a crime, and the light emitting part is turned on or blinking for a certain time and the sounding part is controlled to emit a warning sound for a certain time. For moving objects that are not intended for criminal purposes, it has the effect of preventing excessive threats and also being able to reliably threaten criminal purposes. Detection from moving body sensors and illuminance sensors Based on the signal, it is useful as an illuminating device or the like that functions as ordinary illumination or illumination for crime prevention.
