OPTO-THERMAL SOLUTION FOR MULTI-UTILITY SOLID STATE LIGHTING DEVICE USING CONIC SECTION GEOMETRIES

摘要

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).
