1. A retrofit light emitting diode (LED) bulb comprising:
- a screw connector for screwing the retrofit light emitting diode (LED) bulb into a receiving socket of an electric light fixture for supporting the retrofit light emitting diode (LED) bulb;
a bracket physically attached to the screw connector;
a housing coupled to the bracket, said housing comprising;
one or more LED units for generating light, wherein the one or more LED units is disposed on a front face of the housing arranged to generate light in a direction away from the front face of the housing, wherein said housing being coupled to the bracket permitting an angle such that when the retrofit light emitting diode (LED) bulb is attached to the receiving socket via the screw connector and when the coupling is at the angle then at least a portion of light generated by one or more of the LED units is directed approximately orthogonally from a linear direction at which the screw connector is screwed into the receiving socket;
a rear face of the housing comprising a heat sink thermally integrated to the housing, wherein the heat sink dissipates heat generated responsive to the one or more LED units generating light; and
one or more electrically powered cooling devices to remove heat from the vicinity of the one or more LED units, wherein air flow from the electrically powered cooling devices is approximately in parallel to a direction of the light generated by the one or more LED units and when the housing is rotatably coupled at the angle, the air flow from the electrically powered cooling device is approximately orthogonal to the linear direction, wherein the screw connector is a male screw base, which supports the bracket and housing when the retrofit light emitting diode (LED) bulb is screwed into the receiving socket.
