Lamp Device and Method to Retrofit a Lighting Fixture
First Claim
1. A lamp fixture securable to a structure having an electrical power source, comprising:
- 1) a collar having an annular wall and a base securable to the structure,2) a lamp device comprising a neck base having an annular wall having a shaped outside surface that is placed into direct surface contact with the inner surface of the annular wall of the collar, to establish a heat-transferring interface between the lamp device and the collar, and having a distal end, and3) a light module comprising at least one light source disposed at the distal end of the lamp device.

Abstract
A device and method for retrofitting a light fixture from use with a lamp socket that employs an incandescent or metal halide lamp, to use with another lamp assembly. The lamp fixture has a collar with a base and an annular outer wall extending out from the base. The LED lamp device includes a neck base having an annular outer wall having a shaped outside surface that is placed into direct surface contact with the inner surface of the annular outer wall of the collar, to establish an effective heat-transferring interface. The shaped outer surface of the neck base provides proper fitting of the LED lamp device into the lighting fixture, and provides a heat-transferring interface over substantially all of the outer surface of the neck base, to dissipate heat away from the LED module. Aluminum material provides high thermal conductivity, light weight, availability, and low cost.

- 11. A lamp device for retrofitting into a conventional lamp fixture that has a collar that has a base and an annular outer wall extending out from the base, the lamp device comprising an annular wall having a shaped outside surface that is placed into direct surface contact with the inner surface of the annular wall of the collar, to establish a heat-transferring interface between the lamp device and the collar, and having a distal end configured to receive a light module comprising at least one light source.

17. A method for retrofitting an existing lamp fixture to replace a threaded lamp socket with a lamp assembly, the lamp fixture having a collar having an annular wall with an inner wall surface, and a base to which the threaded lamp socket is secured for attaching the lamp fixture to the structure, and for communicating electrical power from an electrical power source to the threaded socket lamp, the method comprising the steps of:
-
a. removing the threaded lamp socket from the collar; b. providing a lamp device having an annular wall having a shaped outside annular surface and a light module; c. affixing the lamp device to the lamp fixture, wherein the shaped outside annular surface is placed into direct surface contact with the inner surface of the annular wall of the metallic collar, to establish a heat-transferring interface between the adapter sleeve and the collar, and d. connecting the electrical power source to the light module. - View Dependent Claims (18, 19, 20, 23)
