Abstract
A vehicle headlight includes a headlight housing including an external lens and an outer wall that define a headlight interior and a lighting element including a light-emitting diode lamp and an internal heatsink coupled to at least a portion of the lamp. The lamp is in thermal communication with the internal heatsink. The lighting element is disposed within the headlight interior and coupled to an element receptacle defined by the outer wall. The internal heatsink of the lighting element is in thermal communication with the external lens.
Claims20
A vehicle headlight comprising:
- a headlight housing including an external lens and an outer wall that define a headlight interior;
- and
- a lighting element including a light-emitting diode lamp and an internal heatsink coupled to at least a portion of the lamp, wherein the lamp is in thermal communication with the internal heatsink, and wherein the lighting element is disposed within the headlight interior and coupled to an element receptacle defined by the outer wall, and wherein the internal heatsink of the lighting element is in thermal communication with the external lens, the internal heatsink defined by a plurality of parallel elongated members that extend continuously from a rear wall of the headlight housing and below the lighting element to an area between the lighting element and the external lens.
A vehicle headlight comprising:
- a plurality of continuous parallel plates defining an internal heatsink for receiving a lamp, the lamp in thermal communication with the plates;
- and
- a housing including an external lens and an outer wall defining an interior volume, the internal heatsink and lamp disposed within the interior volume, and the parallel plates extending from a rear wall of the housing to a position proximate the external lens and in thermal communication therewith.
An external vehicle lamp comprising:
- a heatsink defined by parallel plates, wherein a portion of the parallel plates define a lamp receptacle;
- a lamp within the lamp receptacle and in thermal communication with the parallel plates;
- and
- a housing including a lens and an outer wall that define an interior volume, wherein the parallel plates and lamp are disposed within the interior volume and wherein the parallel plates are in thermal communication with the lens.
