Abstract

The invention discloses a lighting device used for preventing thefts. The lighting device used for preventing thefts comprises a power supply P, an infrared sensing and light-dependent circuit, a time delay circuit and a lighting device W, wherein the power supply P is connected with the power supply end of the infrared sensing and light-dependent circuit, the signal output end of the infrared sensing and light-dependent circuit is connected with the signal input end of the time delay circuit, and the signal output end of the time delay circuit is connected with the signal input end of the lighting device W. The infrared sensing and light-dependent circuit consists of an infrared sensor D and a processor S, wherein the infrared sensor D comprises three pins and the processor S includes sixteen pins. Through adopting the above structure, the lighting device used for preventing thefts has the advantages of improving the delayed accuracy and enabling the lighting device to prevent thefts.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lighting device for safety and anti-theft. Background technique [0002] The optical system of the infrared sensor can concentrate the infrared radiation energy from multiple directions on the infrared sensor after being reflected or transmitted by a special lens, so that the infrared sensor can detect the change of radiation in a certain three-dimensional protection space. When there is no moving human body and other targets in the guard area, since the infrared radiation energy of all background objects at room temperature is relatively small and basically stable, the camera cannot be triggered, that is, the camera does not work. When the human body walks in the detection area, it will cause changes in the infrared radiation energy. The infrared sensor converts the change of the received infrared thermal radiation energy between the active human body and the background object into a corre...
