Title:
CONTROL SYSTEM FOR ADJUSTING BRIGHTNESS AND G9 LED BULB THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/140010
Kind Code:
A1
Abstract:
A control system for adjusting brightness and a G9 LED bulb thereof. The G9 LED bulb comprises a lamp body, an LED light source (200) and a control system. The lamp body comprises a G9 lamp holder (310) and a PCB circuit board (320). The control system is connected to the LED light source, and the two both are arranged and mounted on the PCB circuit board. The control system comprises a rectifier module (110), a voltage division module (120) and a control module (130). A first side of the rectifier module is connected to the lamp body. The voltage division module is connected between an anode and a cathode of a second side of the rectifier module, and outputs a corresponding power source switch signal to the control module by means of an output end according to the control of a user over a switch of the G9 LED bulb. The control module is provided with a plurality of different drive currents in advance, and is used for providing a corresponding drive current for the LED light source according to the number of times the power source switch signal is provided by the voltage division module. The G9 LED bulb is easily dimmed, and has a small volume, a tight structure and good heat dissipation performance.
