Master-slave remote control dimming lamp

Abstract

The invention relates to the technical field of circuit control, in particular to a master-slave remote control dimming lamp, which comprises a master unit and a slave unit, wherein core control devices of the master unit and the slave unit respectively employ an AT89S52 singlechip microcomputer; the master unit comprises an infrared receiving module, a light brightness acquisition module, a driving module and a light emitting diode (LED) lamp; the brightness of the LED lamp can be controlled by a knob and a keyboard; LED lamp brightness data and environment light brightness data can be stored, and the brightness of the LED lamp is automatically adjusted according to external light; the slave unit transmits a signal to the master unit through infrared remote control, and the turn-on and turn-off of the lamp and the adjustment of the brightness are realized by controlling pulse width modulation (PWM); and the slave unit is in a sleep state or a working state, and if the slave unit is not operated for a long time, the slave unit automatically enters a sleep power-saving state. A peripheral circuit has the characteristics of simplicity, high driving capacity, low cost and high efficiency. The circuit is provided with software and hardware, has a main function of software regulation, and is large in repaired space and high in cost performance.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to a master-slave remote control dimming lamp. Background technique [0002] Most of today's lighting control systems use all kinds of ordinary manual switches to control the switching status of lamps, and the brightness adjustment is also adjusted through ordinary dimmer switches, which cannot be adaptively changed according to the light environment to meet individual needs. The most comfortable brightness. At present, the common remote control lamps on the market are controlled by remote control buttons, and the brightness of the lamps jumps step by step, which cannot achieve stable dimming, and most of the circuits are complex and costly. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and designs a master-slave remote control dimming lamp, which adopts energy-saving high-brightness LED lamps as the light source and...
