Abstract

The invention discloses an intelligent opening and closing circuit for a lighting drawer. The intelligent opening and closing circuit is composed of a transformer T1, a diode bridge-type rectifier U1, an audion VT1, an audion VT2, an audion VT3, a lamp B, a human body infrared sensor and other electronic elements. The intelligent opening and closing circuit for the lighting drawer can automatically supply electricity to light up the lamp when people uses the drawer, and turning off the power supply of lighting automatically when people leaves the drawer; thus the intelligence and practicability of the product are largely improved, energy consumption during the drawer lighting process is better reduced, and service life of the lamp is well promoted.

Description

technical field [0001] The invention relates to an intelligent opening and closing circuit, in particular to an intelligent opening and closing circuit for a lighting drawer. Background technique [0002] The drawer comprises a bottom, a front panel, a rear wall on the opposite side of the front panel and two side walls which move in the direction of movement of the drawer and which embody a fixed connection to the ends of the rear wall Hollow profiles. [0003] The patent application with the patent number 201290001316.7 discloses a drawer with lighting, a lighting device and a current collector, which can control the opening or closing of the lighting lamp through the current collector, so that the lighting can be provided when the drawer is opened, and the lighting can be turned off when the drawer is closed. purpose of lighting. [0004] However, in actual use, people often forget to close the drawer after the drawer is opened, which will cause the lighting of the draw...
