Problems solved by technology
Therefore, when the speed of the moving object is relatively fast, such as a car entering or exiting the garage, because the moving speed of the car is fast, the car has almost passed the position of the LED light at the moment when the previous LED light turns on, but has not yet arrived. The detection range of the next LED light, the next LED light has not turned to the strongest, so the lighting effect of the LED light with an infrared motion sensor is difficult to meet the actual lighting needs

The invention discloses an LED lamp circuit with an infrared motion sensor, which receives an external infrared light signal in real time by setting an infrared receiving module, and when the infrared receiving module receives the infrared light signal, generates a corresponding infrared control signal and sends it to an MCU for control circuit, the infrared motion sensor detects whether there is a moving object nearby in real time, and generates a corresponding detection signal and sends it to the MCU control circuit. The control process of the MCU control circuit is divided into the infrared control stage, the moving object control stage and the normal control stage. Moving objects or receiving infrared light signals emitted by nearby LED lights can make the LED light-emitting module enter a high-brightness state to achieve lighting; the advantage is that multiple LED lights in a certain lighting area can be balanced and adjusted according to lighting requirements, which saves energy. On the basis of this, it can ensure that the fast-moving moving objects are fully illuminated, which is convenient for moving objects and meets the current actual lighting needs.
Description
technical field [0001] The invention relates to an LED lamp circuit, in particular to an LED lamp circuit with an infrared motion sensor. Background technique [0002] In many applications in the current lighting field, in order to save energy, the lighting scheme that the lights are on when people come and go off when people leave is adopted. In this lighting scheme, when a person approaches the LED light, the LED light turns on, and when the person moves away from the LED light, the LED light automatically turns off after a certain time delay. In order to turn on the lights when people arrive and turn off the lights when people leave, this kind of LED lights are equipped with sensors to detect moving objects. The sensors detect whether there are moving objects nearby in real time, and send corresponding control signals according to the detection results. Turn on or off the lights under control. [0003] At present, there are two main types of sensors used in LED lights t...
