Hereinafter, the lighting control device of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a schematic block diagram of a lighting control device according to an embodiment of the present invention. Referring to FIG. 1 , the lighting control apparatus 100 according to the present invention may largely include a distance sensor 10 , a control unit 20 , and a communication module 30 .

In the present invention, the distance sensor 10 is a sensor for detecting the separation distance of the input means 200 located in the front, it may preferably be composed of an infrared distance sensor (10). In this case, the infrared sensor 10 may be composed of a light emitting unit including a light emitting diode (LED) emitting light of an infrared wavelength and a light receiving unit that detects the light again when the irradiated infrared light returns.

At this time, in the distance measurement using infrared rays, when infrared rays are irradiated from the light emitting part of the infrared sensor 10, the infrared rays reach the object to be measured and are reflected. can be used to measure the distance to the recognition object.

The control unit is a part that controls the lighting device according to the separation distance information of the input means 200 sensed by the distance sensor 10 . That is, the control unit 20 according to the present invention sequentially controls the light-off, lighting, and output intensity according to the separation distance of the input means 200 . The operation of the control unit 20 will be described in more detail later.

In addition, in the present invention, the lighting device may include a plurality of lighting modules, and is not limited to a specific lighting device. The plurality of lighting modules may be grouped by a location at which lighting is installed, characteristics of lighting such as psychedelic lighting, etc., and brightness of lighting.

The communication module 30 serves to transmit and receive various information such as a lighting device and a control signal. Such a communication module may be a wireless module. For example, the communication module may use a wireless transceiver. In the case of a wireless transceiver, a signal can be transmitted and received between a lighting switch and a lighting device using ZigBee and Bluetooth. Meanwhile, in some cases, the communication module may use a wired module.

2 is a plan view showing an example of the arrangement of the infrared distance sensor 10 applied to the lighting control device 100 according to the present invention. As shown in FIG. 2, the infrared distance sensor 10 may be formed of a plurality of 10a, 10b, and 10c, and in this case, the plurality of distance detecting sensors 10a, 10b, 10c are arc-shaped within the body case. may be placed. The body case 11 has a plate shape having a predetermined thickness, and may be formed of a synthetic resin material or a metal material.

In the present invention, the input means 200 for detecting the distance by the infrared distance sensor 10 may be a part of the user's body. More specifically, it may be constituted by the user's palm.

According to the present invention, the infrared distance sensor 10 is arranged in an arc shape along the trajectory of the circular motion of the palm around the user's body, so that the user can more easily position the palm on the distance sensor 10 . can be detected. In this case, the arc is preferably arranged within a central angle of 50°, which is an angle at which the palm can naturally rotate around the body.

Accordingly, according to the present invention, the user can quickly and continuously dimming by quickly changing the position of the palm up and down. In addition, by placing the palm at a high point above the distance sensor 10 , after exiting from the sensing area of the distance sensor 10 , and placing it at a lower point again, discontinuous and stepwise dimming is also possible.

In addition, the input means 200 may be made of a bar member. That is, the end of the rod member is divided on both sides so that the separation distance corresponds to the separation distance of the distance sensing sensor 10 may be composed of a rod member spaced apart. Accordingly, according to the present invention, it is possible to control the two distance sensing sensors 10 with one operation.

3 is a plan view showing another example of the arrangement of the distance sensor 10 applied to the lighting control device 100 according to the present invention. As shown in FIG. 3 , the distance sensor 10 may be arranged in a plurality of rows in order to control a plurality of lights. At this time, the distance sensing sensors 10 of adjacent rows are arranged spaced apart from each other in a zigzag form, so that the input means becomes the distance sensing sensor 10 without causing interference between the distance sensing sensors 10.

In addition, in the present invention, the infrared distance sensor 10 needs to prevent scattering of infrared rays emitted from the distance sensor 10 in order to increase the accuracy of distance measurement.

4 is a side cross-sectional view of the arrangement of the distance sensor 10 applied to the lighting control device 100 according to the present invention. As shown in FIG. 4 , the distance sensor 13 may be embedded in the bottom surface of the cylindrical groove 12 in order to prevent scattering of the emitted infrared rays. In this case, the inner peripheral surface of the cylinder groove 12 may be formed as a light absorption surface (a).

Accordingly, according to the present invention, the light irradiated to the inner peripheral surface of the cylinder 12 among the infrared rays emitted from the distance sensor 10 is absorbed by the light absorption surface (a), and only the light irradiated to the opening of the cylinder 12 is of the cylinder. It is emitted to the outside to sense the distance of the input means 200 (left side of FIG. 4).

As a result, light having a large irradiation angle is absorbed and only light having a small irradiation angle is emitted to the outside of the cylinder groove 12 . At this time, the irradiation angle refers to the angle between the central axis direction of the cylinder groove 12 and the irradiation direction of the light beam, and the large irradiation angle refers to the light irradiated from the central axis in the direction of a large departure angle. The small angle refers to light irradiated in a direction similar to the central axis.

Accordingly, in the case of the embodiment according to the present invention, since the straightness of infrared light is excellent, more precise distance measurement is possible. Meanwhile, in the case of the above embodiment, as can be seen from FIG. 4 , the intensity of the light emitted to the outside of the cylinder is weak, and thus the signal intensity tends to be weakened.

Meanwhile, on the right side of FIG. 4 , an embodiment in which a light reflection surface b and a light absorption surface a are respectively formed on the inner circumferential surface of the cylinder groove 12 is shown. At this time, the light reflecting surface (b) may be formed by inserting an inner cylinder having a light reflecting surface such as a reflecting mirror on the inner surface of the cylinder 12,

Accordingly, in the present embodiment, the light irradiated to the light absorbing surface (a) among the infrared rays emitted from the distance sensor 10 is absorbed, and the light irradiated to the light reflective surface (b) is reflected at the same angle to the cylinder ( 12) It is released to the outside. Accordingly, while maintaining the upward straightness of the infrared rays, the amount of infrared rays emitted to the outside of the cylinder 12 is greater than that of the above-described embodiment, so that a stronger signal strength can be maintained.

In particular, according to the present invention, the irradiation angle range of the light source can be adjusted by adjusting the insertion length of the inner cylinder. That is, when more precise distance measurement is required, the distance measurement precision can be maintained by reducing the insertion length of the inner cylinder and maintaining the light absorption surface (a) large, thereby improving the straightness of the light emitted to the outside. When the signal strength is required, the length of the insertion of the inner cylinder is increased to increase the amount of infrared rays emitted to the outside of the cylinder groove 12 so that the signal strength can be maintained strong.

In addition, in the present invention, the infrared distance sensor 10 needs to prevent interference between infrared light emitted from the distance sensor in order to increase the accuracy of distance measurement. In this case, since interference of infrared light more easily occurs between similar wavelengths, it is required to minimize it.

Therefore, according to the present invention, it is preferable that the plurality of distance sensors 10a, 10b, 10c, .. are driven using infrared rays having different wavelengths, respectively. In this case, it is preferable that the infrared wavelengths between the adjacent distance sensors 10a, 10b, 10c, .. are different from each other, and more preferably, the wavelengths between the adjacent distance sensors 10a, 10b, 10c, ..) are different from each other. It is better to maximize the difference.

For example, when using 6 distance sensors, the wavelength band can be set to f, f-10, f-20, f-30, f-40, f-50, and at this time, the distance sensors adjacent to each other can be set. It is preferable to set the wavelengths between them in the order of f, f-20, f-40, f-10, f-30, f-50.

Accordingly, according to the present invention, it is possible to measure a more precise distance by minimizing wavelength interference between the adjacent distance sensors 10a, 10b, 10c, ..

In the present invention, the lighting control device 100 may be configured to further include a smart controller (40). 5 is a perspective view illustrating a screen of the smart controller 40 applied to the lighting control device 100 according to the present invention, and FIG. 6 is a perspective view illustrating another screen.

5 to 6 , the smart controller 40 may set a matching relationship between the distance detecting sensor 10 and the lighting module controlled by the distance detecting sensor 10 . In this case, the lighting module may be grouped according to the type and location of the lighting, and the distance sensor 10 may be matched for each group.

Specifically, the grouping as described above may be set according to the contents of the performance program. That is, according to the performance program, it is possible to divide the lighting following a fixed control and the lighting following a variable control, etc., and control the lighting following the variable control by woven integrally. In this case, the grouping may be grouped by location according to the location of the lighting installation, that is, each lighting may be independently controlled for each grouped location, such as front lighting, rear lighting, side lighting, etc. of the performance hall. Also, the smart controller 40 may set whether the distance sensing sensors 10 are individually activated as shown in FIG. 6 .

Accordingly, according to the present invention, it is possible to control more lighting modules using a smaller number of distance sensors 10 . In addition, it becomes possible to provide various lighting effects such as lighting sequence, intensity, and color of lighting according to the characteristics of each lighting module. In particular, it becomes possible to create a more lively performance hall atmosphere by performing immediate lighting control on some lights by reflecting the on-site situation.

Hereinafter, the operation of the distance sensor 10 according to the present invention will be described.

7 is a view for explaining the operation relationship of the input means according to the present invention. When the operation of the infrared distance sensing sensor 10 is described with reference to FIG. 7 , as described above, an object to be recognized that exists at a distance away from the sensing unit can be detected using the infrared sensor using infrared characteristics. As such a sensing unit, a sensing surface included in the infrared sensor will be described as an example.

That is, the infrared sensor includes a sensing surface, and the object to be recognized is detected in the sensing section including the first section (A), the second section (B), and the third section (C) according to the separation distance from the sensing face. do. In this case, the first section (A) may be an on/off section of the power of the lighting device, and the second section (B) and the third section (C) may be a dimming section for dimming the brightness of the lighting device. In addition, the first section (A), the second section (B), and the entire third section (C) may be a dimming section.

In the dimming period, the brightness may be continuously adjusted according to the distance. For example, the first period (A) for each period is a first brightness stage period, and the second period (B) is a second brightness stage period and a third period. (C) may be divided into a third brightness level section. Meanwhile, the number of brightness step sections in the dimming section, the separation distance between each brightness step section, or the brightness value of each brightness step section may be set in various ways depending on the case.

In addition, the lighting control apparatus 100 according to the present invention may be to perform a user authentication process according to the input pattern of the input means (200). In this case, the input pattern may be specified by any one of the input order of the input means 200 for each distance sensor, an input position, or an input duration, or a combination thereof.

For example, when the user's palm is sensed for 1 second in the first section (A) and then detected in the third section (C), it may be specified that the locking device is released. Also, for example, when the input means 200 is sensed in the order of ①, ②, and ③ as shown in FIG. 5, it may be specified as a lighting signal of a specific lighting module.

In addition, the lighting control apparatus 100 according to the present invention may further include an optical measuring device (not shown) installed on the subject side to sense the illuminance, color temperature and color of the subject.

Accordingly, the lighting control device 100 according to the present invention. Any one or more of illuminance, color temperature, and color may be automatically feedback-controlled based on the measured value of the optical measuring device. Accordingly, there is an advantage in that, when the lighting of several different products is used at the same time, the inconvenience of manually adjusting the color temperature, etc. can be eliminated each time.

For example, according to the present invention, the range of the effective input section of the distance sensor 10 can be adjusted according to the illuminance measurement value of the optical measuring device.

That is, when the average value of illuminance for a specific time measured by the optical measuring device is greater than the reference value, this means that the overall lighting control for the subject is too bright. Accordingly, in this case, the illuminance of the subject can be lowered by increasing the range of the effective input section of the distance sensor 10 . However, in this case, the larger the separation distance of the input means 200, the greater the output intensity. In addition, when the average value of illuminance measured by the optical measuring device for a specific time is smaller than the reference value, this means that the overall lighting control for the subject is too dark. Accordingly, in this case, it is possible to increase the illuminance of the subject by lowering the range of the effective input section of the distance sensor.

That is, when the height of the user controlling the lighting is large, the control space area is formed at a high position, so it is necessary to set the effective input section of the distance sensor to be high, and when the height is small, the control space area is formed at a low position. It is necessary to set the effective input range of the distance sensor to be low. Accordingly, according to the present invention, it is possible to perform customized control according to the user's physical condition.

To this end, according to the present invention, it may further include a display unit (not shown) for outputting the illuminance, color temperature and color information collected by the optical measuring device and transmitting the information to the control unit.

On the other hand, Figure 8 is a block diagram showing a control sequence in the lighting control apparatus 100 according to the present invention. Referring to FIG. 8, the operation sequence of the lighting control device 100 according to the present invention will be described. As described above, the step of detecting an input means located within the detection section using a distance sensor (S100); transmitting the sensed distance information of the input means to the control unit (S200); The control unit reads the distance information of the input means (S300) and controls the lighting device according to the read distance information (S400).

As described above, the lighting control device according to the present invention controls the lighting according to the position of the user's input means using the infrared distance sensor, thereby facilitating various lighting effects such as turning on, turning off, and adjusting the output for a plurality of lights. Since the input means for lighting control can be intuitively and sensibly recognized, there is an advantage that instant dimming or fast switching is possible.

In particular, the lighting control device according to the present invention has an effect that the lighting control act itself can be sublimated into a performance in a concert hall, etc. because the input means for lighting control is made by a user's operation.

The present invention relates to a lighting control device, and the lighting control device of the present invention uses an infrared distance sensor to control lighting according to the position of the user's input means, thereby providing various lighting such as lighting, turning off, and output control for a plurality of lights.
