Abstract

The invention discloses a pyroelectric infrared scene-change-induction lighting control system and a method thereof. The system comprises a sampling control unit, a photosensitive element, a pyroelectric infrared induction sampling element, a power supply circuit, a cold white light emitting diode, a warm white light emitting diode, a red light emitting diode, a green light emitting diode, and a yellow light emitting diode. The sampling control unit includes a processor, a first duty ratio output unit, a second duty ratio output unit, a third duty ratio output unit, a fourth duty ratio output unit, a fifth duty ratio output unit, an anti-jamming filtering processing unit, and an average-mean filtering algorithm unit. Through the pyroelectric infrared scene-change-induction lighting control system and the method thereof, lighting scene change is realized. The system and the method have the advantages of simple circuit, high detection precision, high reliability, small external influence, and strong practicability.

Description

technical field [0001] The invention relates to the technical field of lighting control systems, in particular to a pyro-infrared induction scene change lighting control system and a method thereof. Background technique [0002] As the application range of LED lamps becomes wider and wider, high-power and high-brightness LED chips emerge as the times require; in recent years, with the successful development of high-power and high-brightness LED chips and the continuous improvement of their reflective Brightness LEDs are beginning to enter the lighting field. [0003] There are various forms of LED lighting control systems in the prior art; however, for the existing LED lighting control systems, it is difficult to realize scene changing lighting. Contents of the invention [0004] The purpose of the present invention is to provide a pyro-infrared induction scene change lighting control system for the deficiencies of the prior art. The pyro-infrared induction scene change l...
