Abstract
Electrical lighting housings and heat sinks constructed of pitch-based carbon fiber that act as heat sinks for light emitting diode (“LED”/“LEDs”) lights. Greater heat dissipation cools the LED lights and power suppling components, which in turns increases the life span of these components, without the need for active cooling. Due to the improved physical strength of pitch-based carbon fiber over aluminum and other typical heat sink and housing materials, the wall thickness of a housing can be decreased when using pitch-based carbon fiber which can further aid in thermal transfer.
Claims10
A light fixture comprising:
- a housing adapted to receive a printed circuit board having at least one light emitting diode;
- the printed circuit board being in contact with the housing;
- and
- wherein at least a portion of the housing in contact with the printed circuit board is constructed of pitch-based carbon fiber.
A method of manufacturing a light emitting diode light fixture comprising the steps of:
- fabricating a pitch based carbon fiber impregnated with a resin putty;
- compressing and heating the pitch based carbon fiber impregnated with the resin putty to a predetermined pressure and a predetermined temperature until the pitch based carbon fiber impregnated with the resin putty has cured, creating a pitch-based carbon fiber part;
- deflashing and cleaning the pitch-based carbon fiber part;
- and
- attaching a printed circuit board having at least one light emitting diode to the pitch-based carbon fiber part.
