Abstract
A light source holder includes a spherical surface and a number of recessed portions. The recessed portions are defined in the spherical surface and arranged substantially evenly over the spherical surface. Each of the recessed portions comprises a plurality of inner surfaces. The inner surface of each recessed portion comprises a bottom surface and a lateral reflective surface. The bottom surface is capable of having a solid-state light source arranged thereon. The lateral reflective surface is adjacent to the bottom surface and configured for reflecting light emitted from the solid-state light source and outputting the light from the recessed portion.
