International Classification:

F21V 2300
H01R 3372

US Classification:

362368

Abstract:

An apparatus and method of manufacture for a light source housing apparatus. The housing is insert molded around a plurality of electrically separated leads and defines a cavity. A portion of each lead is exposed along a bottom surface of the housing. Two or more leads have terminal portions near a rear surface of the housing. A lead, which can be used to protect against electrostatic discharge, is also mounted along a front face of the housing and terminates at a ring portion which defines an opening that is aligned with the cavity. The opening of the ring portion is preferably sized and shaped to correspond to an outer peripheral surface of a lens, lightpipe or other optical media, so that the lens can be inserted through the ring portion and into the cavity. A light source, such as an LED, is mounted within a cutout of the housing. The housing is manufactured using lead sets each having pre-formed leads indexed by a leadframe through an injection mold to form the housing around each lead set.
