Linear light source for enhancing uniformity of beaming light within the beaming light's effective focal range
First Claim
1. A light guide assembly for enhancing uniformity of beaming light, comprising:
- a polygonal cylindrical light guide bar, wherein one surface of the light guide bar is a light-scattering/light-emission surface and other surfaces are a plurality of reflecting surfaces, and at least one end of the light guide bar is a light-receiving end, wherein the light-scattering/light-emission surface comprises an indented surface;
a light source assembly connecting to said light guide bar, wherein said light source assembly includes at least one light emitting diode; and
a reflective housing encasing said light guide bar, and an emission opening in reflective sleeve formed corresponding to the light-scattering/light-emission surface; and
an angle of said indented surface is gradually increased with an incline angle of 0.03 to 0.15 degrees.

Abstract
A light guide assembly as a linear light source for enhancing the uniformity of beaming light within the beaming light'"'"'s effective focal range comprising a light guide bar connected to a light source assembly and a reflective housing encasing the light guide bar. One surface of the light guide bar is a light-scattering/light-emission surface, and other surfaces are all reflective. The emission plane has gradually changing indentations for adjusting the light refractive and reflecting indexes to ensure the light uniformity. The reflective housing covering the light guide bar is used for enhancing the light reflection and intensity. An opening is formed in the reflective housing corresponding to the emission plane of the light guide bar, and a reflecting flange is formed at one side of the opening. Combined with the sloping and notched emission plane, light with high intensity and uniformity can be obtained, and the uniformity of beaming light within the beaming light'"'"'s effective focal range can also be improved.
