The invention provides a corridor LED lighting lamp based on human body induction, which solves a problem that the existing corridor lighting lamps are not sensitive enough in reaction. The scheme isthat the corridor LED lighting lamp comprises a lamp holder and a lighting control circuit in the lamp holder, the lighting control circuit in the lamp holder includes an infrared sensing amplification circuit, a light-operated switch, a monostable trigger circuit and a thyristor control circuit, the infrared sensing amplification circuit is connected with the monostable trigger circuit, the light-operated switch is connected with the monostable trigger circuit, and the monostable trigger circuit is further connected with the thyristor control circuit. The corridor LED lighting lamp is simplein structure, a light emitting diode (LED) is automatically turned on when a person enters the infrared induction range, and the LED is continuously turned on when the person leaves the infrared induction range; and the LED is automatically turned off in a delayed manner after the person leaves. The LED is automatically turned on when a person gets close to the infrared sensing range, and the LEDis automatically turned off when the person leaves the infrared sensing range, thereby being friendly, convenient, safe and energy-saving.
Description
technical field [0001] The invention relates to the technical field of pyroelectric infrared sensing, in particular to a corridor LED lighting fixture based on human body induction. Background technique [0002] In order to save energy, my country generally adopts sound-light dual-control delay lights or other control mode delay lights in corridor lighting according to international requirements. For a long time, it has played a great role in saving electric energy. With the development of the times and the advancement of science and technology, the use of LED lighting can save energy. [0003] However, the sound-light dual-control corridor lighting also has its own disadvantages: if the sound control device is too sensitive, it will mistake other sounds as the sound signal when people enter the corridor, such as loud noise caused by wind at night or thunder in rainy days The sound often causes the acousto-optic dual-control corridor lighting to work all night, wasting elect...
