ABSTRACT:
A miniaturized linear light source sub-module comprising a symmetrical lens array, a light guide bar with dual reflecting surfaces, at least one light emitting diode light source, and a sub-module housing is disclosed. The symmetrical lens array comprises two identical covers, two identical lens sections, and a middle holder. Each lens section comprises a plurality of lenses disposed on the top and bottom of the lens section. The dual reflecting surface light guide comprises a light emitting surface, a v-shaped light reflecting surface, an asymmetrical saw-toothed light reflecting surface, an apex cut-off surface, and a bottom cut-off surface. At least one light emitting diode light source is connected to an end of the dual reflecting surface light guide. The sub-module housing holds the lens array assembly, the dual reflecting surface light guide, and the at least one light emitting diode light source to form the miniaturized linear light source sub-module.
