An outdoor lighting fixture using LEDs as a light source has a decorative housing that includes a cast metal dome roof and one or more LED light engines, wherein the light engines conductive metal substrate is in conformal contact with a portion of the inner surface of the roof, such that the roof provides increased heat sink mass and the outer surface of the roof provides a heat dissipative surface area outside of the housing. Preferred embodiments include a street light wherein two LED light engines are mounted at about 20 and 160 degrees to a line parallel to the street segment to produce an asymmetric light profile that reaches over and along the street for an effective distance, but does not extend very far on the side away from the street. Also disclosed is a reflector module for an LED light engine having rows of cone reflectors modified to produce an effective emission pattern.

Outdoor lighting fixture using LEDs

A light emitting diode (LED) lighting device that includes a housing and a heat sink assembly received within the housing. The heat sink assembly includes at least a first heat sink member and at least a second heat sink member. A printed circuit board having at least one LED provided thereon is mounted to both the first heat sink member and the second heat sink member. At least one biasing member biases an outer side of the first heat sink member and an outer side of the second heat sink member into contact with an inner side of the housing. Heat from the at least one LED is transferred through the heat sink assembly to the housing, where it is dissipated into the air.

Housing for emitters for infrared detectors

Housing for a plurality of emitters for detectors

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. After the insert molding process at least a portion of the leadframe is removed to electrically isolate the leads. If used with surface mount technology, the housing is preferably self-aligning.
