Constant Voltage Dimmable Led Driver
view source
US Patent:

8497637, Jul 30, 2013
Filed:

Apr 13, 2011
Appl. No.:

13/066388
Inventors:

Gang Gary Liu - Plano TX, US
International Classification:

H05B 37/02
H05B 39/04
H05B 41/36
F02P 3/08
US Classification:

315225, 315209 CD, 315172
Abstract:

A constant voltage dimmable LED (Light Emitting Diode) driver is disclosed that is compatible with all types of dimmers, including conventional phase cut (TRIAC) dimmers, and behaves like a conventional constant voltage driver which can be connected to any size of LED load that has a matching voltage rating. The driver produces a continuous train of pulses for driving the LED load and obtains an averaged measure of the voltage at the AC input for controlling the duty cycle of the continuous train of pulses. Therefore, when the averaged measure of the voltage at the AC input is reduced by a dimmer, the duty cycle reduces, resulting in a dimmed LED. The driver can be created by adding a few components to a conventional wide input range AC-DC converter without or with very little modifications.
