Abstract

A LED light source includes one or more LED light source arrangements, wherein each of the LED light source arrangements includes a LED member having a first light emitting surface and an opposed second light emitting surface, and two fluorescent members on top of the first and second light emitting surfaces of the LED member respectively to retain the LED member in position such that the illumination generated from the LED member is capable of passing through the two fluorescent members from the two light emitting surfaces respectively. The LED light source arrangement provides illumination at an angle greater than 180° and direct effective heat dissipation at all sides of the LED member.
