Since LED is a point light source, it is easy to cause uneven illumination in the dark center around
In some occasions, such as dormitories, hotel lobbies, studios and large parking lots, remote roads and other places, people's activities are often only in a certain part. If the LED lights are lit for a long time at full load, it will not only affect the life of the LED lights. impact, there is still a waste of resources

The invention discloses a zoned dimming system comprising a microcontroller and further comprises an infrared sensor module, a constant current drive circuit module, a motor and a light source module which are connected with the microcontroller. The signal output end of the infrared sensor module is connected to the signal input end of the microcontroller, the output end of the microcontroller is connected to the motor and the input end of the constant current drive circuit module, and the motor and the output end of the constant current drive circuit module are connected to the light source module. When a person in a zone is detected, the infrared sensor module inputs person position signals to the microcontroller, the microcontroller controls the motor to drive the light source module to rotate and points to a corresponding position, and meanwhile, the bright of the light source module is adjusted.
Description
technical field [0001] The invention relates to a zone dimming system, in particular to a zone dimming system for realizing intelligent and humanized dimming control on light source lamps. Background technique [0002] As the world's most attention-grabbing new-generation light source, LEDs are widely used because of their advantages such as high brightness, low heat, long life, non-toxicity, and recyclability. But in actual use, there are still some problems of resource utilization. Since LED is a point light source, it is easy to cause the problem of uneven illumination in the dark center around. In some occasions, such as dormitories, hotel lobbies, studios and large parking lots, remote roads and other places, people's activities are often only in a certain part. If the LED lights are lit for a long time at full load, it will not only affect the life of the LED lights. impact, there is also a waste of resources. Contents of the invention [0003] The present inventi...
