Dimming Control

Dimming control is used for energy saving scheme in most of the general lighting system. There are different kinds of dimming control methods in the lighting device. This paper aims to provide a general discussion on the power circuit to lighting up the LED devices and it also discusses the possible way to dim the LEDs. Moreover, this paper based on the 3W high power LED and aims to find out the best operating factors that can fully utilize LED and to provide best energy saving scheme.

Led Drivers

High-power LED street-lighting with advantages including long lifespan, great luminescent efficiency, lower power consumption and superior environmental performance has received more and more attention. However, the lifespan of corresponding LED drivers fails to match with that of LEDs. The main reason is that in tight and confined spaces, high heat flux cannot be emitted to surroundings, which lead to the increased temperature of electric devices in LED driver. In this paper, high conductive micro heat pipes (MHPs) are applied in the cooling system. Firstly, the Icepak thermal simulation software is applied in analog contours of temperature of interior driver. Then experiments are carried out to measure the temperature of electric devices of LED driver. The results indicate that internal temperature of LED driver is decreased by 5°C when MHP is applied, compared with the original thermal design. The capacitor and MOSFET which are sensitive to heat and easy to damage run under optimized temperature.
