Dimming method for office lighting

Dimming LED Lighting

LED lighting has the potential to offer many benefits to the user and to society as a whole. Very high efficiency together with extremely long life expectancy of the LEDs reduces the energy consumption and the use of resources, and can offer low lifecycle cost. In order to become widely accepted, LED lighting must provide dimming capability at least equivalent to that offered by traditional inc...

LED Backlight Driving Circuits and Dimming Method

In this paper, light-emitting-diode (LED) backlight driving circuits and dimming method for medium-sized and large liquid crystal displays (LCDs) are proposed. The double loop control method, the intelligent-phase-shifted PWM dimming method, the fast-switching current regulator, and the current matching techniques are proposed to improve not only the current regulation characteristics and the p...
