my country is paying more and more attention to energy conservation and emission reduction, an indicator that is called for by the world. Especially in the construction industry, how to efficiently improve energy utilization has become an important construction indicator, and lighting is the most important factor for energy conservation in buildings. part. With the gradual maturity of light-sensing technology, the accuracy of light detection is getting higher and higher, and the measurement change value that is close to the human eye can be read out. It is because of such mature technology that light-sensing technology is applied In many fields, and in the field of lighting, many energy-saving products combined with light perception have been enthusiastically launched.

If the corridor lights and corridor lights on the building are turned on for a long time, the power consumption will be huge, which obviously violates the purpose of energy saving and emission reduction. Here, embedding light-sensing technology can just solve this problem. The light sensor can respond to the architectural lighting through the detected ambient light value. However, the existing light sensor application only realizes the on/off control of the lamp, and cannot adjust the lamp according to the actual brightness of the environment. There is still much room for improvement in terms of emission reduction.

detailed description

The scheme of this application is further described in conjunction with the accompanying drawings as follows:

Example 1:

Referring to accompanying drawing 1, a kind of wireless sensor adaptive energy-saving dimming system, it comprises a light controller 1 and a light sensor 2, and this light sensor 2 has MCU (the model is stm8l051f3p6) 21, light sensing device 22, ZigBee module 23 and battery 24, the MCU 21 wakes up or sleeps the ZigBee module 23 or/and the light sensing device 22 according to its low power consumption mechanism. Wake or sleep control.

The lighting controller 1 is connected with a lamp or a lighting system 3 , which communicates with the light sensor 2 through a ZigBee network, and is used to control the lamp or lighting system according to the light data fed back by the light sensor 2 . Specifically, the light controller 1 has a set value or preset value for the lighting scene, so as to maintain the light output at the set value or preset value level; The light source is complementary, so that the ambient light is fixed at a certain lumens, which can alleviate the damage to the human eye caused by too strong light, and also has the effect of saving energy.

The above scheme works by:

The lumen of the ambient light is detected by the light sensing device 21 , and the MCU 21 converts the real-time detection value into a data packet and sends it out through the ZigBee module 23 .

After receiving the signal data, the lighting controller 1 compares the real-time detection value with the lumens set by itself. If the current lumens of the lights is less than the lumens set by itself, it will drive the lamps or lighting system by outputting corresponding PWM signals. 3 to increase the light output brightness until the real-time detection value reaches the lumen level set by yourself, and stop the adjustment of the lamp or lighting system 3; otherwise, if the current lumen of the light is higher than the lumen set by yourself, then through the output corresponding PWM signal to drive lamps or lighting system 3 to reduce light output brightness.

In this way, the ambient light can achieve the desired brightness effect.
