Lighting control system

The present invention relates to a lighting fixture control system that provides intelligent lighting effects and reduces the energy consumed by lighting.

Conventional lighting devices are dominated by incandescent lamps and fluorescent lamps. Among them, incandescent lamps are inexpensive and provide a stable, non-flashing light source, but their luminous efficiency is not good. Although the fluorescent lamp has a high luminous efficiency, it needs to be additionally provided with a starter and a ballast, so that noise is often generated when used, and the light source of the fluorescent lamp may flicker.

With the advancement of technology, lighting devices have gradually evolved into power-saving bulbs and LED (light-emitting diode) lamps. The electronic ballast is integrated in the power-saving bulb, and its structure is relatively strong, and its luminous efficiency is much higher than that of incandescent lamps.

When the control machine 11 judges that a preset image appears in the imaging area 183, the illumination lamp 15 of the illumination area 181 overlapping the imaging area 183 is turned on.

In different embodiments, the positions of the respective lighting fixtures 15 and the respective network camera units 17 can also be set and stored in the control machine 11, for example, the respective lighting fixtures 15 and the respective network camera units 17 are coded, wherein the illumination area is The lighting fixture 15 and the network camera unit 17 that overlap the 181 and the imaging area 183 may have the same or related codes. When the control machine 11 determines that a preset image appears in the imaging area 183 of the network camera unit 17, the lighting fixture 15 having the same or associated code as the camera unit 17 will be turned on.

Through the lighting control system 10 of the present invention, the preset image of the control machine 11 can be set so that the control machine 11 can pass through the controller only when the preset image enters the imaging area 183 of the network camera unit 17. 13 and/or the power supply unit 12 turns on the lighting fixture 15 or increases the brightness of the lighting fixture 15. Therefore, when the preset image enters the imaging area 183 and remains stationary, the lighting fixture 15 corresponding to the imaging area 183 is not turned off, and the brightness is not lowered. In addition, when other objects that do not belong to the preset image enter the imaging area 183 or move within the imaging area 183, the lighting fixture 15 is not turned on.

In contrast, the prior art can only simply control the opening or closing of the lighting device, and cannot turn on or off the lighting source according to the actual needs of the user, which not only causes inconvenience in use, but also fails to achieve energy saving.

In an embodiment of the present invention, the lighting fixture control program 111 installed on the control machine 11 can adjust the brightness and/or color temperature of the lighting fixture 15 according to the user's setting. Specifically, the lighting fixture control program 111 can adjust the color temperature of the lighting fixture 15 according to time. For example, the color temperature of the lighting fixture 15 can be adjusted to about 5000K during the day to improve the working efficiency of the personnel, and the color temperature of the lighting fixture 15 can be adjusted at night. It is about 3000K to alleviate the nervousness of overtime workers. In addition, the lighting fixtures 15 can reduce the brightness during the lunch break to facilitate the rest of the staff. The color temperature adjustment mode of the lighting fixture 15 will be described in detail in the following embodiments.

Specifically, the mobile communication device 16 can communicate with the control device 11 via a wireless router 193, and transmits a setting data 161 to the control device 11 via the wireless router 193. The control device 11 outputs a control signal 143 according to the setting data 161. The brightness and/or color temperature of the lighting fixture 15 is adjusted to provide a wider range of applications for the lighting fixture control system 10, wherein the setting data 161 can be the brightness, color temperature, and time of the lighting fixture 15. In actual application, the router 191 and the wireless router 193 can also be integrated into a single device.
