First Claim
Patent Images
1. A vehicle light assembly comprising:
- a light source disposed on a printed circuit that is enclosed by a thermal conductive member;
an optic configured to output light emitted by the light source;
the thermal conductive member enclosing the light source and the optic and thermally coupled to a vehicle body via a thermal transfer adhesive, wherein the thermal conductive member comprises one or more inclined outer sidewalls and one or more inner sidewalls that surround the light source and extend at an angle relative to the printed circuit board, and wherein a gap between the one or more inner sidewalls widens vertically as the one or more sidewalls extend away from the printed circuit board; and
a sealing adhesive that seals the thermal transfer adhesive between the thermal conductive member and the vehicle body, wherein the thermal transfer adhesive is provided at a central rear portion of the thermal conductive member and the sealing adhesive is provided about a rear peripheral region of the thermal conductive member and encloses the thermal transfer adhesive.

6. A vehicle light assembly comprising:
-
a light source disposed on a printed circuit board; a thermal conductive member having one or more inclined outer sidewalls and a barrel that encloses the light source; an optic disposed in the barrel and configured to output light emitted by the light source, wherein the thermal conductive member transfers heat produced by the light source to a vehicle body via a thermal transfer adhesive coupling the thermal conductive member to the vehicle body, and wherein the barrel is defined by one or more sidewalls extending at an angle relative to the printed circuit board; and a sealing adhesive that seals the thermal transfer adhesive between the thermal conductive member and the vehicle body, wherein the thermal transfer adhesive is provided at a central rear portion of the thermal conductive member and the sealing adhesive is provided about a rear peripheral region of the thermal conductive member and encloses the thermal transfer adhesive. - View Dependent Claims (7, 8)
