Abstract
The disclosed subject matter provides a reflecting cover above and between a light-emitting chip and a projection lens. The diffused light from the light-emitting chip is led toward the projection lens via the reflecting cover such that it transmits through the projection lens at a certain angle. This makes it possible to increase the amount of controllable light, and to improve the amount of light beams radiated from the lamp, thereby realizing a brighter lamp and an improved light distribution shape.
