Abstract
A light emitting apparatus comprising an at least substantially omnidirectional light assembly including an LED-based light source within a light-transmissive envelope. Electronics configured to drive the LED-based light source, the electronics being disposed within a base having a blocking angle no larger than 45°. A plurality of heat dissipation elements (such as fins) in thermal communication with the base and extending adjacent the envelope.
Claims34
A light emitting apparatus comprising a light transmissive envelope;
- a light emitting diode light source illuminating the interior of the light transmissive envelope;
- said light source in thermal communication with a base element;
- and a plurality of surface area enhancing elements in thermal communication with said base element such that said elements are communicating optically with said light transmissive envelope.
A light emitting apparatus comprising a base element having a light blocking angle of between 15° and 45°;
- a light emitting diode light source in thermal communication with said base element;
- a plurality of surface area enhancing elements in thermal communication with said base element, wherein said surface area enhancing elements increase the thermal dissipation capacity of said apparatus by a factor of 4× and absorb less than 10% of an emitted light flux.
A light emitting device comprising at least one light emitting diode;
- a heat sink, said heat sink having a relatively smaller size proximate to the at least one light emitting diode and a relatively larger size distal from said diode;
- said at least one light emitting diode positioned in thermal communication with said heat sink;
- an electrical connection positioned adjacent said distal portion of said heat sink;
- a light diffusing envelope extending from said heat sink and encompassing said at least one light emitting diode;
- a plurality of diffuse or specular fins in thermal communication with said heat sink and extending therefrom radially adjacent said envelope, said fins having a first relatively thin section adjacent said heat sink, a second relatively thin section adjacent the envelope distal from said heat sink and a relatively thicker intermediate section, wherein said device is dimensioned to meet ANSI C78.20-2003.
