Modular architecture for sealed LED light engines
First Claim
Patent Images
1. A method of fabricating a light source, the method comprising:
- providing a predetermined number of sealed light engine modules (SLEMs), each SLEM comprising;
a) a lamp including a lens and a body shell where the body shell is seated on a distal end of a base member and a socket cup is fitted to a proximal end of the base member and the lamp is sealed with a sealing ring that mates with the lens and body shell to substantially resist the ingress of contaminants;
b) a light emitting diode (LED) module housed within the light chamber, wherein the LED module receives electrical excitation to convert the electrical excitation into light output;
mounting the SLEMs to a support plate of a light assembly;
slidably installing the light assembly into a base; and
installing end caps onto the base to substantially contain an electrical interface of each of the mounted SLEMs.

Abstract
Apparatus and associated methods involve an assembly of multiple LED light engines in which a desired number of LED lamps are mounted to a plate that forms a wall of an enclosure. In an illustrative example, three LED light engines may be mounted to a plate that may be slidably installed as a wall of an extruded housing that contains electrical connections from an AC power inlet to each light engine. In various examples, the number and layout arrangement of the LED light engines may be custom selected for a particular application.

7. A light source comprising:
-
a predetermined number of sealed light engine modules (SLEMs), each SLEM comprising; a) a lamp including a thermal spreader having a distally extended pocket formed in a central portion thereof that receives a LED module; b) a lens and body shell where the lamp is sealed with a sealing ring that retains the lens against a reflector that is in thermal communication with the thermal spreader to substantially resist the ingress of contaminants; and c) a light emitting diode (LED) module housed within the light chamber, wherein the LED module is configured to receive electrical excitation from an electrical interface and to supply conditioned electrical excitation to provide light output; a light assembly having a support plate configured to have the SLEMs mounted thereon; a base configured to slidably receive the light assembly; and end caps configured to be installed onto the base to form an enclosed volume that substantially contains the electrical interface of each of the mounted SLEMs. - View Dependent Claims (8, 9, 10)
