VEHICLE LAMP USING SEMICONDUCTOR LIGHT-EMITTING DEVICE
The present invention relates to a vehicle lamp and, more particularly, to a vehicle lamp using a semiconductor light-emitting device. The present invention provides a vehicle lamp comprising: a substrate; first and second bar-shaped light sources arranged parallel to one side of the substrate and extending along one direction thereof; and a lens disposed on one surface of the substrate and extending along the one direction so as to overlap with the first and second light sources, wherein the cross-section of the lens, which is perpendicular to the extending directions of the two light sources and cut along a virtual plane perpendicular to the substrate, includes a part of an ellipse.
System and Method for High Efficiency Forward Lighting Collimating Projection System
A forward projecting condensing and collimating optical platform enables the ability to more effectively utilize the light generated from a Lambertian light source. The optical system can effectively utilize light emitted from a 120-degree source viewing angle over a substantially large extended field of view. The optical system can project a high intensity light in a smaller packaging envelope. The optical design can be used for generation of hi-Intensity spot beams, fog lamps, head lamp low beams, head lamps, hi beams, a driving beam, and the like, while operating at a lower power input to equivalent optical systems.
