Abstract
An illustrative thermally managed light includes a light source, for example an LED array, a heatsink having a tapered outer surface, the light source thermally coupled with the heatsink, a housing having a tapered interior surface portion, and a securing device coupling the heatsink and the rear end of the housing. The securing device, for example a tensioning device, adapted to retain the outer surface of the heatsink in thermal contact with the tapered interior surface of the housing, thus transferring and dissipating the heat from the light source into the environment around the housing.
Claims20
A thermally managed light, comprising:
- a light source;
- a heatsink having a tapered outer surface, the light source thermally coupled with the heatsink;
- a housing having an interior surface, at least a portion of the interior surface tapered to receive the tapered outer surface of the heatsink;
- and
- a coupling device securing the heatsink with the housing such that the tapered outer surface of the heatsink is thermally coupled with the tapered interior surface of the housing.
A thermally managed light, comprising:
- an LED;
- a disk-shaped heatsink having a conical outer surface, the LED thermally coupled with the heatsink;
- a housing having an interior surface, at least a portion of the interior surface shaped to receive and match the conical outer surface of the heatsink;
- and
- a coupling device securing the heatsink with the housing such that the conical outer surface of the heatsink is thermally coupled with the interior surface of the housing.
A thermally managed light, comprising:
- a light source;
- a heatsink having a tapered outer surface, the light source thermally coupled with the heatsink;
- a housing having an interior surface, at least a portion of the interior surface tapered to receive the tapered outer surface of the heatsink;
- and
- a coupling device securing the heatsink with the housing such that the tapered outer surface of the heatsink is in direct mechanical and thermal contact with the tapered interior surface of the housing, the coupling device including a bracket and a fastener coupled between the heatsink and a rear portion of the housing, the fastener accessible from outside the housing.
