Abstract
The utility model discloses an LED indoor illumination control system based on a single-chip microcomputer. The LED indoor illumination control system comprises a pyroelectric infrared detection module, an ambient brightness detection module, a temperature detection module, the single-chip microcomputer, an LED drive and an LED. The pyroelectric infrared detection module, the ambient brightness detection module and the temperature detection module are connected with the single-chip microcomputer. The single-chip microcomputer is connected with the LED drive and the LED. The pyroelectric infrared detection module is formed by a Fresnel lens, a pyroelectric infrared sensor (FIR), a control module and a drive circuit. The Fresnel lens senses heat and transmits the heat to the pyroelectric infrared sensor (FIR); and the pyroelectric infrared sensor (FIR) is connected with the control module and the drive circuit. The beneficial effects of the LED indoor illumination control system are that the indoor illumination automatically controls the switch and the brightness of the LED, thereby achieving very good energy saving and illumination environment improving effects; and the system is simple in structure, strong in practicability, and can be suitable for apartments, corridor lamps of offices, and illuminating lamps in toilets and the like.
