Abstract

A LED light bar, a related planar light source and a method of manufacturing such light bar is provided. The light source includes a light guide plate having a first surface and a second surface; at least one light bar, on which a plurality of LEDs is disposed, wherein the light bar is disposed on a lateral side of the light guide plate, and the LEDs are disposed inside the light guide plate to output light; a reflector, which is disposed outside the second surface and reflects light; and a diffuser, which is disposed outside the first surface and scatters reflected light of the reflector. Because LEDs are pre-disposed in a mold when the light guide plate is manufactured, the LEDs and the light guide plate are integrally formed, the loss of light can be avoided, and the efficiency of the planar light source can be enhanced.
