Abstract

An LED utility light has a one or more LED devices supported by a mounting structure and electrically connected to a mounting base section and to a boss and base cap for electrical engagement with a receptacle. LED device circuitry and conductive leads are located in the mounting structure and the mounting base section. A housing substantially surrounds the mounting structure.

Claims

1. A light comprising:

a mounting structure,

a plurality of light-emitting diodes (LEDs) attached to the mounting structure,

a mounting base section attached to the mounting structure,

a boss which extends from the mounting base section,

an electrically conductive lead which extend from the boss to the mounting structure to conduct electricity to the plurality of LEDs,

a base cap connected to the boss, the base cap in electrically conductive contact with the conductive lead, and

a housing which substantially surrounds the mounting structure and is in contact with the mounting base section, the housing having an opening through which the boss extends

wherein the housing comprises a transparent portion and a non-transparent portion.

2. The light of claim 1 wherein the boss and base cap are located outside of the housing.

3. The light of claim 1 wherein the non-transparent portion of the housing further comprises a reflective coating facing the mounting structure.

4. The light of claim 1, the plurality of LEDs are arranged in a generally rectangular array on a surface of the mounting structure.

5. The light of claim 1, wherein the housing is generally cylindrical.

6. The light of claim 1, in combination with a receptacle wherein the base cape is engaged with the receptacle and is in electrical contact with the receptacle.
