Description

【Technical field】 [0001] The invention relates to the field of office lighting control, in particular to an automatic induction and adjustable LED lighting drive control system capable of energy-saving lighting for office lighting lamps, which can also be called an automatic induction and adjustable LED office lighting drive control system. 【Background technique】 [0002] As energy issues attract more and more people's attention, energy saving has become an aspect that cannot be ignored in production and application. Lighting is required in offices, roadsides, and public places. Turning on and off can not only meet the needs of lighting, but also save electricity. Therefore, most places will follow the office lighting controller. [0003] The current office lighting controllers mainly include timing control, sound-activated delay control and light-sensing control to turn on and off the lighting. Timing control is generally controlled according to the time of day and night, ...

AI Technical Summary

Problems solved by technology

[0004] Although the light sensing control has the control effect of energy saving, the circuit of the current light sensing controller is too simple, especially the controller of office lighting, which has a single control method and has the following defects:

[0006] 2. All office lighting controllers can only realize the operation of turning on or off, but cannot automatically adjust the intensity of lighting according to the intensity of light. As long as the lighting adjustment is achieved, all lighting fixtures will be turned on, so that the effect of energy saving will be affected. had a great impact

[0007] 3. The current office lighting controllers do not take into account the light differences in multiple different environments at all. They all use a single lighting point, which makes the control not precise enough, which affects normal use or causes unnecessary waste of electric energy.

[0008] 4. The current office lighting controller does not take into account the difference between indoor and outdoor light at all. In the case of abnormal and changeable weather, it will still cause a lot of waste. For example, one day the sky is covered with dark clouds and the brightness is not enough. Then the controller will control the lights to turn on, but soon the clouds will clear and the fog will clear, and the weather will clear up. At this time, the effect of the lights can be basically ignored, but because there is still a small amount of fog in the indoor environment, the lights will not be automatically turned off immediately. caused waste

[0009] 5. In the extreme weather of lightning, the controller will mistakenly think that the light is sufficient due to the increase in light and turn off the light, which will cause greater panic for users in thunder and lightning weather (for example: it is raining outside the office, the light is dark, The controller controls the lighting to turn on, and a lightning flashes outside the window at this time, the controller thinks that the lighting is good, so it controls the lighting to turn off, which causes panic and trouble in use), all current controllers have not fully realized this problem, It is also unable to solve this problem in extreme weather, so that users do not trust the stability of the light-sensing controller, and would rather choose other controllers
