Abstract

A light fixture, comprising a matrix, a plurality of electrical sockets fixedly secured to the matrix and forming a rigid matrix of electrical sockets electrically interconnected in two dimensions. One or more light emitting diode modules are individually removable and replaceable within any individual electrical socket within the matrix. Each individual light emitting diode module includes a base and a light emitting diode, wherein the base is configured and arranged for fitted electrical engagement within the electrical socket.

Claims

1. A light emitting diode light bulb comprising:

a heat sink;

a base integrated into and thermally coupled to the heat sink;

a light emitting diode thermally coupled to the integrated base and heat sink;

a pair of light emitting diode contacts extending from the light emitting diode and coupled to the integrated base and heat sink, each light emitting diode contact shaped to removeably mate in retentive contact with corresponding power source contacts coupled to a power supply to produce light;

wherein the integrated base and heat sink, light emitting diode contacts, and power source contacts provide a friction fit to electrically connect the respective contacts.

2. The light emitting diode light bulb of claim 1 wherein the pair of light emitting diode contacts comprise male connectors for mating with the power source contacts.

3. The light emitting diode light bulb of claim 1 and further comprising a lens optically coupled to the light emitting diode to provide a widely dispersed beam of light.

4. The light emitting diode light bulb of claim 3 wherein the light emitting diode is adhered to the integrated base and heat sink to provide a seal to protect the light emitting diode.
