Abstract:
A LED light apparatus includes a conical reflection housing and a LED light source. The reflection housing has a vertex, a light opening aligning with the vertex, an inner flat reflection surface. The LED light source includes a light head alignedly pointing towards the vertex, wherein when the light head generates light a first portion of the light is accumulatively reflected by the reflection surface towards the light opening while a second portion of the light is projected towards the non-reflection arrangement to prevent the second portion of the light being reflected back to the light source for minimizing a black spot occurring at the light opening. Accordingly, the wide light pattern is refocused into a narrow beam pattern to improve the lighting efficiency. The distribution of the light output is regulated, and the heat generation is reduced.
