LED outdoor lights can usually be divided into microwave type, voice control type, touch type, infrared type, and so on. The working principle of the infrared sensor lamp is that after passing through the induction module, its automatically controlled light source lights up through the transmission of sound, touch, infrared, etc.
This kind of lamp is easy to use and can also save electricity. The working principle of the light sensor light is that the light sensor module first detects the intensity of the light, and decides whether to put the modules of the LED infrared sensor light on standby and lock. There are two cases:
(1) During the day or when the light is relatively strong, the light sensor module locks the infrared sensor module and the delay switch module according to the sensing value.
(2) At night or when the light is relatively dark, the light-sensing module puts the infrared sensing module and the delay switch module on standby according to the sensing value.
At this time, if a human body enters the sensing range of the lamp, the infrared sensing module will start and detect the signal, and the signal triggers the delay switch module to turn on the LED infrared sensing light. If the person continues to move within the range, the LED human body sensor light will be always on. When the person leaves the range, there is no infrared sensor signal, and the delay switch automatically turns off the LED infrared sensor light within the time set value. Each module returns to the standby state, waiting for the next cycle.
