Title: Led dimming method and dimming device
Inventor: YOSHIDA EIKI
IPC: H05B37/02
Filed: 2010-03-23
Abstract: PROBLEM TO BE SOLVED: To provide an LED dimming device superior in responsibility and capable of preventing luminance unevenness and flickering caused by noise by generating a pulse signal of aTTL input/output level synchronized with a phase control power wave and supplying the pulse signal to an LED.SOLUTION: In this LED dimming method, LED dimming is performed by using the phase control power wave from an AC power supply. After carrying out the full-wave rectification of the phase control power wave, a first pulse signal stepped down to the TTL input/output level is generated by smoothly slicing the full wave rectified wave, a second pulse signal rectified into a rectangular shape is generated by making the edge of the first pulse signal steep, and dimming control synchronized with the phase control power wave is performed by supplying the second pulse signal to the LED.
