LED lamp heat sink
First Claim
1. An apparatus comprising:
- a shell;
an optical reflector disposed at least partially within the shell, wherein a space is formed between the optical reflector and the shell;
at least one light emitting diode disposed within the optical reflector;
a heat sink disposed at least partially within the shell, the light emitting diode being mounted to the heat sink; and
a motor and a fan in flow communication with the space, the fan being configured to move air over the heat sink and through the space.

Abstract
An LED lamp includes an exterior shell that has the same form factor as a conventional incandescent light bulb, such as a PAR type bulb. The LED lamp includes an optical reflector that is disposed within the shell and that directs the light emitted from one or more LEDs. The optical reflector and shell define a space that is used to channel air to cool the device. The LED is mounted on a heat sink that is disposed within the shell. A fan moves air over the heat sink and through the spaced defined by the optical reflector and the shell. The shell includes one or more apertures that serve as air inlet or exhaust apertures. One or more apertures defined by the optical reflector and shell at the opening of the shell can also be used as air exhaust or inlet apertures.

11. A method of cooling a light emitting diode in a lamp, the lamp including an optical reflector that directs the light emitted from the light emitting diode, the method comprising:
-
drawing air through at least one air inlet aperture;
moving the air over a heat sink that is coupled to the light emitting diode;
moving the air along at least a portion of the optical reflector; and
expelling the air through at least one air exhaust aperture. - View Dependent Claims (12, 13, 14, 15, 16)
