Abstract

The invention provides a human body pyroelectric infrared induction control circuit applicable to electrodeless lamps, which comprises a clock circuit, an optical detection circuit, an infrared signal processing circuit, a power circuit and an output control circuit. The infrared signal processing circuit receives human body pyroelectric infrared induction signals, amplifies the received signals then filters interference, and then outputs the signals to the output control circuit. The human body pyroelectric infrared induction control circuit filters detection signals through the infrared signal processing circuit, so as to ensure that the detection signals are more accurately processed, and gain can be variable during processing after magnification at two stage, so that the receive sensitivity of human body pyroelectric infrared induction is improved, and further the limited range of monitoring can be adjusted. The human body pyroelectric infrared induction control circuit is not operated at day time, is energy-saving and intelligent, is applicable to non-resistive load, such as electrodeless lamps and the like, and has a long service life.

Description

technical field [0001] The invention relates to a control circuit, in particular to a human body pyroelectric infrared induction control circuit suitable for an electrodeless lamp. Background technique [0002] Human pyroelectric infrared sensor switch circuit can detect the presence of human body within a certain range because it can receive the far infrared emitted by the human body, so it is widely used in human body detection occasions, such as equipment safety protection devices and lighting control in public places Lighting occasions, the lighting control of public places can realize automatic lighting when people are detected to pass by, thus facilitating our lives, but the traditional infrared sensor switch is not suitable for the use of non-resistive loads such as electrodeless lamps. It is easy to malfunction during use. The traditional infrared sensor switch is only suitable for pure resistive loads, and its life is likely to be greatly shortened when used ...
