Abstract:
In one aspect, the disclosure relates to a light emitting assembly for an instrument panel, which includes a light guide assembly a light guide assembly body and at least one light transmissive leg extending from the light guide assembly body. The leg has a light input surface along an edge in close proximity to a light emitting diode. The leg may be integral with the body at an intersection that forms a prismatic Y shaped light reflective structure at the body. The prismatic Y shaped light reflective structure forms an angle of reflection surface at the intersection with the body of a predetermined angle of reflection to reflect light from the leg to the light guide assembly body. The reflected light ray is refracted substantially uniformly through the light guide assembly body to produce substantially uniform illumination of the light guide assembly.
