Opto-thermal solution for multi-utility solid state lighting device using conic section geometries

Abstract

A light assembly 1100 includes a cover 18, a housing 16 coupled to the cover 18 and a lamp base 14 coupled to the cover 18. The light assembly 1100 also includes a first circuit board 30 disposed within the housing 16. The first circuit board 30 has a plurality of light sources 32 thereon. A heat sink 210 is thermally coupled to the light sources 32. The heat sink 32 includes a plurality of spaced-apart layers 1140 having outer edges and openings therethrough. Each of the outer edges 1144 are in contact with the housing 16. The light assembly also includes an elongated control circuit board assembly 1110 electrically coupled to the light sources 32 of the first circuit board 30 and the lamp base 14. The control circuit board 1110 extends through the openings 1170. The control circuit board 1110 has a plurality of electrical components 1112 thereon for controlling the light sources 32.
