Heat transfer system for a light emitting diode (LED) lamp
View Patent ↗A heat transfer system is provided for a LED lamp. The LED lamp includes a board surface to supply heat energy during an operation of the LED lamp. The LED lamp is mounted within a recessed housing that separates a first area having a first temperature from a second area having a second temperature, where the second temperature is lower than the first temperature. The system includes a thermal dissipator positioned within the second area. The system further includes a heat transfer device with a first end mounted to the board surface, and a second end mounted to the thermal dissipator, to transfer the heat energy from the board surface in the first area to the thermal dissipator in the second area, and dissipate the heat energy within the second area.
1. A heat transfer system for a light emitting diode (LED) lamp, said LED lamp comprising a board surface configured to generate heat energy during an operation of the LED lamp, said LED lamp positioned within a lamp body and mounted within a recessed housing for separating an attic having a first temperature from a room having a second temperature, said second temperature being lower than said first temperature, wherein the lamp body is mounted within the recessed housing at an opening in a ceiling of the room, said ceiling for separating the attic having the first temperature from the room having the second temperature, said system comprising:
a trim positioned within the room, wherein said trim comprises:
a longitudinal surface configured to extend in a direction parallel to a longitudinal axis of the lamp body, from a first end coupled to the ceiling to a second end within the room;
a radial surface configured to extend in the outward radial direction from a first end, to a second end attached to the second end of the longitudinal surface; and
a flow profile attached to a base of the lamp body, said flow profile comprising a redirecting channel; said first end of the radial surface to extend within the redirecting channel, such that the flow profile is configured to redirect the generated flow of air over a second side of the radial surface, said second side being opposite to a first side of the radial surface facing the ceiling;
a heat pipe having a first end mounted to the board surface, and a second end mounted to the trim, to transfer the heat energy from the board surface to the trim and to dissipate the heat energy from the trim within the room; and
an air flow device configured to generate a flow of air along the trim, said trim configured to direct the generated flow of air in an outward radial direction over the trim, to enhance the dissipation of the heat energy from the trim within the room.
2. The system of claim 1 , wherein said air flow device is mounted on the first side of the radial surface, between the radial surface and the ceiling, to generate the flow of air in an inner radial direction over the first side of the radial surface; wherein said redirecting channel is shaped to receive the generated flow of air and to redirect the generated flow of air in the outward radial direction over the second side of the radial surface.
3. The system of claim 2 , wherein said redirecting channel has a U-shaped profile, and said first end of the radial surface is configured to extend within the U-shaped profile.
4. The system of claim 1 , wherein said air flow device is mounted on an exterior surface of the lamp body, to generate the flow of air in a direction parallel to the longitudinal axis of the lamp body; wherein said redirecting channel is shaped to receive the generated flow of air and to redirect the generated flow of air in the outward radial direction over the second side of the radial surface.
