发明名称 LED lamp
摘要 A lamp comprises an optically transmissive enclosure and a base. An LED assembly is located in the enclosure and is operable to emit light when energized through an electrical path from the base. The LED assembly comprises an LED and a lumophoric dome that surrounds the LED. A partially reflective pad is on the lumophoric dome for manipulating the pattern of light emitted from the lumophoric dome. A heat sink comprises a heat dissipating portion that is at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the LED. An optically transmissive lens emits light from the enclosure where the lens comprises an annular area defined by a textured surface and a transparent area interior of the annular area.

主权项 1. A lamp comprising: an enclosure being at least partially optically transmissive; a base; at least one LED located in the enclosure and operable to emit light when energized through an electrical path from the base; a lumophoric dome remote from the at least one LED and surrounding the at least one LED where the lumophoric dome comprises an inside surface and an outside surface, the at least one LED disposed horizontally and positioned adjacent the bottom of the lumophoric dome; a heat sink comprising a heat dissipating portion that is at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the at least one LED; an at least partially reflective and partially transmissive pad positioned in the the lumophoric dome between the inside surface and the outside surface, the pad disposed over at least the top of the lumophoric dome opposite the at least one LED and extending for less than the entire dome for manipulating the pattern of light emitted from the lumophoric dome such that some of the light is redirected toward the sides of the lamp.
