The invention relates to an electric light source technology, in particular to a night garage infrared sensor switch dimming LED lamp. The night garage infrared sensor switch dimming LED lamp comprises a light-emitting diode LED lamp, a voltage-stabilizing chip of LM7805 model, a human body infrared sensor of AMNI model, a light-out delay circuit of a time-base chip of NE555 model, a dimming pulse generator of a time-base chip of NE555 model, a pulse PWM dimming high-power driving chip of PT41 model, a relay and a power adapter, wherein an output of the human body infrared sensor is connected with the light-out delay circuit, an output of the voltage-stabilizing chip is connected with a power supply end of the dimming pulse generator, an output of the pulse PWM dimming high-power driving chip is connected with the light-emitting diode LED lamp, and the light-emitting diode LED lamp is arranged in a garage. The night garage infrared sensor switch dimming LED lamp is suitable for illumination in the garage at night, is turned on when a person and a vehicle enter and exit, is turned off when the person and vehicle leave or the vehicle is parked, saves time and electricity, and prevents the vehicle from being scraped.
Description
technical field [0001] The invention relates to electric light source technology, in particular to an infrared induction switch dimming LED lamp in a garage at night. Background technique [0002] There is no lighting in the garage at night, so it is inconvenient to enter and exit, and there are potential safety hazards including collisions. However, it is easy to forget to turn off the lights when entering and exiting the garage with lights, which consumes electricity unintentionally, and the brightness of the lights cannot be adjusted. Contents of the invention [0003] The purpose of the present invention is to provide garage lighting at night, a night garage infrared sensor switch dimming LED lamp that automatically lights up lights when people and vehicles enter and exit, and turns off lights after people and vehicles leave or park vehicles in the garage after a short delay. [0004] Technical solution of the present invention: including light-emitting diode LED lamp...
