Beschreibung
Zusammenfassung:	The utility model discloses a pyroelectric infrared induction lamp comprising an induction control unit and a lighting unit, wherein the induction control unit comprises a pyroelectric infrared probe and a pyroelectric sensor processing chip; the output end of the pyroelectric infrared probe is connected with the input end of the pyroelectric sensor processing chip; a Fresnel lens is arranged in the front of the pyroelectric infrared probe; the pyroelectric sensor processing chip comprises an operational amplifier, a comparator and a capacitance resistance oscillator; the output end of the pyroelectric sensor processing chip is connected with a Schmitt trigger; and the output end of the Schmitt trigger is connected with the lighting unit. The pyroelectric infrared induction lamp can automatically induce a pyroelectric infrared signal sent by a human body without manual operation, so that energy waste caused by the fact that a person always forgets to turn off the light when leaving away is avoided.
