Abstract
A light emitting diode (LED) system that includes a LED, a heat sink, a fan housing, a fan, and a cover is disclosed. The heat sink is typically coupled to the LED, and the fan housing is typically coupled to the heat sink opposite the LED. The fan housing is sized to fit within an electrical junction box and includes a fan housing aperture that extends through the fan housing. A cover may be coupled to the fan housing opposite the heat sink. The system may include at least one air intake opening and at least one air exhaust opening. When activated, the fan may external air into the fan housing through the air intake opening and direct the air toward the heat sink and ultimately through the air exhaust opening. In so doing, the temperature of the heat sink and the LED is reduced.
Claims23
A light emitting diode (LED) lighting system, comprising:
- one or more LEDs;
- a heat sink coupled to the one or more LEDs, the heat sink comprising an outer periphery, a platform, two sink walls, and two air exhaust openings extending through the platform, each air exhaust opening positioned between a different sink wall of the two sink walls and the platform;
- a fan housing coupled to the platform of the heat sink opposite the one or more LEDs, the fan housing comprising two opposing end walls each positioned between a different sink wall of the two sink walls and the outer periphery of the heat sink, two opposing sidewalls positioned between the two end walls, two opposing dividing walls coupled to the two opposing end walls and each comprising a terminating end aligned with and adjacent to a different one of the two sink walls, two outer openings positioned between a different end wall of the two end walls and a different dividing wall of the two dividing walls, a fan housing aperture within the fan housing positioned between the two dividing walls, and a cover coupled to the end wall opposite the heat sink;
- a fan coupled to the fan housing and positioned at least partially within the fan housing aperture, wherein airflow enters the fan housing through the two outer openings, passes through the fan housing aperture to interface the heat sink, and exits through the two air exhaust openings responsive to activation of the fan.
A light emitting diode (LED) lighting system, comprising:
- one or more LEDs;
- a heat sink coupled to the one or more LEDs, the heat sink comprising a platform, a sink wall, and an air exhaust opening heat sink;
- a mounting ring coupled to the heat sink opposite the one or more LEDs, the mounting ring comprising one or more screw holes positioned to mount the LED lighting system to an electrical junction box mounted to a flat surface;
- a fan housing coupled to the platform of the heat sink opposite the one or more LEDs and sized to fit within a single gang electrical junction box, the fan housing comprising an end wall, a dividing wall coupled to the end wall and comprising a terminating end aligned with and adjacent to the sink wall, an outer opening positioned between the end wall and the dividing wall, a fan housing aperture within the fan housing, and a cover opposite the heat sink;
- a fan coupled to the fan housing and positioned at least partially within the fan housing aperture, wherein, responsive to activation of the fan, airflow enters the fan housing through the outer opening, passes through the fan housing aperture to interface with the heat sink, and the exits through the air exhaust opening of the heat sink.
A method of mounting a light emitting diode (LED) lighting system to a flat surface, comprising:
- inserting a fan housing of the LED lighting system into an electrical junction box adjacent the flat surface, the fan housing comprising an end wall, a dividing wall, an outer opening positioned between the end wall and the dividing wall, and a fan housing aperture within the fan housing with a fan mounted therein;
- and
- coupling a heat sink of the LED lighting system to the electrical junction box, the heat sink being coupled to the fan housing and comprising a platform adjacent the fan housing, a sink wall adjacent the dividing wall, and an air exhaust positioned on a side of the dividing wall opposite the outer opening such that, responsive to activation of the fan, air flows into the housing through outer opening, through the fan housing aperture, and out of the LED lighting system through the air exhaust opening.
