Title:
DIMMING CONTROL SYSTEM AND METHOD FOR LED LAMP
Document Type and Number:
WIPO Patent Application WO/2016/127679
Kind Code:
A1
Abstract:
Disclosed are a dimming control system and method for an LED lamp. The dimming control system for an LED lamp comprises a transformer, a controller, an LED driving power supply, and a lamp body. The LED driving power supply is a narrow-voltage LED driving power supply. The beneficial effects are: because the voltage change amplitude capable of being adapted by the narrow-voltage LED driving power supply is small, there are conventional technology biases that the narrow-voltage LED driving power supply is not applicable to an LED lamp body; however, the present invention overcomes the conventional technology biases; by making full use of the characteristic that the voltage change amplitude capable of being adapted by the narrow-voltage LED driving power supply is small, the brightness changes of the LED lamp body are controlled according to voltage changes, and accordingly the dimming objective is achieved. In addition, multiple LED lamp bodies are disposed on a same linear power supply guide rail, and accordingly the effects of the present invention can be better implemented; in large sites such as a supermarket, a shopping mall, a conference site, a basement and a subway station, the brightness of multiple lamp bodies on a same power supply guide rail can be directly controlled, and accordingly the dimming in a larger scope can be implemented.
