In this study, the significant factors can cause glare on different conditions of the road light are identified by the design of experiment and simulation. The results are useful to help people avoid the discomfort glare and be safety when they are near the load lights.
The daylighting illumination system is used to guide the natural light indoors for illumination. In this paper, we present a novel design of a lighting window to be used in the day lighting system. The lighting window consists of two freeform microstructures which allow the natural light passing through to a confined space such as an underground basement. Integrating with a compensating LED lighting,...
Because of advantages such as long lifetime, low power consumption, and no mercury containing, LEDs are widely used in a variety of general-purpose illumination applications. There are two different approaches for generating white light with LEDs. The first one is the combination of phosphors excited by blue or UV LED emission, the other one is mixture of multi-color LEDs Without the power loss in...
