Abstract

The invention discloses a light illumination control system. The light illumination control system comprises a DALI host and an LED slave, wherein the LED slave comprises a single chip U3 and a rectifier bridge D1, the alternating current input end of the rectifier bridge D1 is connected with the DALI host through a DALI bus, and the direct current output end of the rectifier bridge D1 is connected with the single chip U3 through a communication receiving-emitting module and an optical-coupling isolating circuit; the communication receiving-emitting module comprises transistors Q1, Q2 and Q3; the optical-coupling isolating circuit comprises an optocoupler U1 and an optocoupler U2; the LED slave further comprises light emitting diodes D2, D3 and D5, a voltage regulator tube D4 and a capacitor C1. The light illumination control system is capable of controlling the light brightness, group, scene, broadcast, automatic addressing and the like and conforms to the IEC60929 and IEC62386 standards, and the modularized design enables the system developing difficulty to be greatly simplified, the developing period to be shortened, and the production efficiency to be improved.

Description

technical field [0001] The invention relates to a lighting system, in particular to an intelligent lighting control system using the DALI protocol. Background technique [0002] The DALI protocol (Digital Addressable Lighting Interface, DALI) is mainly used in the field of intelligent lighting, which can customize personalized lighting scenes and improve power efficiency. The lighting system using DALI protocol includes DALI host, LED slave, control panel, sensor, etc. At present, the whole system is relatively complicated. It is very difficult for general LED lamp manufacturers to design and produce DALI lighting system, and the development cycle is relatively long, which is not conducive to Promotion and application of DALI system. [0003] Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an intelligent lighting control system using the DALI protocol, which can greatly simplify the design difficulty and save t...
