Marker lamp with LED array and prismatic diffuser
First Claim
1. A lamp assembly comprising:
- a prismatic diffuser formed out of a solid section of transparent material, wherein said diffuser is formed with a multiplicity of facets that are angularly offset from each other including at least two said facets that define an outwardly directed section relative to a structure to which said assembly is attached and at least one of said multiplicity of facets other than said outwardly directed facets is formed with an opening; and
a light-emitting source disposed in said facet opening.

Abstract
A lamp assembly (10) for use as a vehicle marker lamp or a vehicle clearance lamp is disclosed. A lamp assembly includes a multifaceted prismatic diffuser (12) to which a number of LEDs (14) are fitted. The diffuser has an outwardly directed portion (20), a center portion (22), and an inwardly directed portion (24). The outwardly directed portion and inwardly directed portion are both formed with angularly offset facets (26-38). The LEDs are fitted into openings (40) that are formed in the facets (32, 34) of the inwardly directed portion of the diffuser. When the LEDs are energized, the light emitted thereby is initially diffused throughout all of the diffuser. It is then emitted from the facets forming the outer portion of the diffuser such that it can be seen over a wide viewing angle.
