Intelligent lamp circuit

Abstract

The invention relates to an intelligent lamp circuit which comprises a brightness detection circuit, a radar induction circuit, an infrared thermopile induction circuit, a signal processing circuit, an electronic switch circuit, an LED lamp circuit and a power supply circuit. The power supply circuit provides power; the brightness detection circuit, the radar induction circuit and the infrared thermopile induction circuit are connected with the input terminal of the signal processing circuit. The electronic switch circuit is connected with the signal processing circuit, and the electronic switch circuit is connected with the LED lamp circuit; the signal processing circuit sends a switching signal to the electronic switch circuit, so that the electronic switch circuit sends an electric control signal to the LED lamp circuit, and the LED lamp circuit controls an LED lamp to be turned on or turned off. Radar, infrared and brightness detection technologies are adopted and comprehensively applied, detection of movement and stillness of a human body in the daytime and at night is achieved, and the sparking problem is solved through an electronic switch without a mechanical contact.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an intelligent lamp circuit. Background technique [0002] At present, the known human body sensing lamp circuit in the market is mainly radar sensing or infrared sensing, both of which are based on the detection of the movement of the object. The static existence of the human body, the lamp can only be extinguished, and cannot be adjusted according to the brightness, which brings inconvenience to use and affects the practicality and limitations of the lamp with the intelligent induction circuit. In addition, the known radar detection lamps adopt a split type, and a relay is used as a switch to switch the AC power supply, so as to achieve the switching lamp mode, which is difficult to install and poses a safety hazard at the same time.
