LED light bulb
First Claim
1. A light emitting diode-based bulb comprising:
- a bracket;
a housing translatably coupled with the bracket, the housing having;
at least one light emitting diode (LED) unit disposed on a front face of the housing arranged to generate light in a direction away from the front face of the housing; and
a rear face of the housing with a heat sink thermally integrated into the housing,the heat sink including at least one heat dissipating member extending outwardly from the rear face of the housing to dissipate heat generated by the at least one light emitting diode (LED) unit; and
a fan attached to the rear face of the housing, the fan operably configured to generate airflow that removes the heat generated by the least one light emitting diode unit.

Abstract
A light emitting diode-based bulb that includes a bracket and a housing translatably coupled with the bracket. The housing includes at least one light emitting diode (LED) unit disposed on a front face of the housing arranged to generate light in a direction away from the front face of the housing and a rear face of the housing with a heat sink thermally integrated into the housing. The heat sink including at least one heat dissipating member extending outwardly from the rear face of the housing to dissipate heat generated by the at least one light emitting diode (LED) unit. A fan is attached to the rear face of the housing, where the fan generates airflow that removes the heat generated by the least one light emitting diode unit.

11. A light emitting diode-based bulb comprising:
-
a bracket with a connector, which is a male screw base, arranged to be connected in an existing light fixture, and which supports the bracket when screwed into a female electrical socket; a housing coupled to the bracket and having; at least one light emitting diode (LED) unit disposed on a front face of the housing arranged to generate light in a direction away from the front face of the housing; and a rear face of the housing comprising a set of vanes extending longitudinally along the housing on the rear face, wherein the set of vanes are part of a heat sink thermally integrated into the housing, wherein the vanes dissipate heat generated by the at least one light emitting diode (LED) unit; and a fan attached to the rear face of the housing, the fan operably configured to generate airflow that removes the heat generated by the least one light emitting diode unit in a direction away from the housing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 23)

25. A method of servicing a light-emitting diode-based bulb comprising:
-
removing an existing light bulb from a receptacle disposed in a horizontal orientation within an electric fixture; and replacing the existing light bulb with a new light emitting diode (LED) bulb having; a bracket; a housing coupled with the bracket, the housing including; at least one LED unit disposed on a front face of the housing arranged to generate light in a direction away from the front face of the housing; and a rear face of the housing with a heat sink thermally integrated into the housing, the heat sink including at least one heat dissipating member extending outwardly from the rear face of the housing to dissipate heat generated by the at least one LED unit; and a fan attached to the rear face of the housing; and installing the new LED bulb within the electric fixture such that the fan generates airflow removing heat generated by the least one LED unit in a direction that is approximately parallel to the direction of the light generated by the at least one light emitting diode unit and approximately orthogonal to the horizontal orientation of the receptacle for the existing light bulb.
