SOLID STATE LIGHT UNIT AND HEAT SINK, AND METHOD FOR THERMAL MANAGEMENT OF A SOLID STATE LIGHT UNIT
First Claim
1. A solid state lamp assembly comprising:
- a heat sink comprising a heat dissipating surface and a heat collecting surface, the heat collecting surface having one or more thermo bosses protruding therefrom;
a printed circuit board having at least one through hole and a light element mounting area located adjacent to the through hole, the printed circuit board mounted in the lamp assembly adjacent to the heat sink such that the thermo boss extends into the through hole; and
at least one solid state lighting element mounted to the printed circuit board at the mounting area, at least a portion of the solid state lighting element covering the through hole such that the solid state lighting element contacts the thermo boss.

Abstract
A lamp assembly manages thermal energy output from solid state lighting elements. An aspect of the present disclosure provides a lamp assembly that achieves enhanced cooling of light elements within the assembly. Enhanced cooling is achieved, in this aspect, by providing a lamp assembly including a heat sink having a plurality of thermo bosses protruding therefrom on a first side, and a plurality of heat sink fins on a second side. A printed circuit board is secured to the first side of the heat sink, and has a plurality of through holes that correspond to the size and locations of the thermo bosses, such that when the printed circuit board is secured to the heat sink, the thermo bosses extend into the through holes.

13. A method for managing thermal output of a solid state lamp assembly, comprising:
-
providing a mounting substrate with at least one through hole corresponding to a location where at least one solid state light element is mounted to the substrate; interconnecting the mounting substrate to a heat sink assembly, the heat sink assembly comprising at least one boss that protracts from the heat sink and extends into an associated through hole of the mounting substrate; and contacting the at least one thermo boss to an associated at least one solid state light element to create a thermal path to conduct heat away from the associated solid state light element. - View Dependent Claims (14, 15, 16, 17)
