摘要:
A high-efficiency LED lamp is disclosed. Embodiments of the invention provide a high-efficiency, high output solid-state lamp. The lamp includes an LED assembly, an optical element disposed to receive light from the LED assembly, and an optical overlay. The optical element includes a primary exit surface, wherein the primary exit surface is at least about 1.5 inches from the LED assembly. In example embodiments, the optical element is roughly cylindrical in shape, but can take other shapes and be made from various materials. An LED lamp according to some embodiments of the invention has an efficiency of at least about 160 lumens per watt. In some embodiments, the lamp has a light output of at least 1200 lumens. In some embodiments, the LED lamp produces light with a color rendering index (CRI) of at least 90 and a warm white color.
摘要:
A lighting device in which a solid state light emitter in a first multi-chip light emitter is spatially offset relative to a solid state light emitter in a second multi-chip light emitter. A lighting device comprising first, second and third multi-chip light emitters, in which any solid state light emitter in the second multi-chip light emitter that is spatially offset relative to a first solid state light emitter on the first multi-chip light emitter by less than 10 degrees emits light of a hue that differs from the hue of light emitted by the first solid state light emitter by more than seven MacAdam ellipses. A solid state light emitter support member comprising a center region and at least first, second and third protrusions extending from the center region. A lighting device comprising at least a first housing member, and means for emitting substantially uniform light.

摘要:
A gas cooled LED lamp and submount is disclosed. The centralized nature of the LEDs allows the LEDs to be configured near the central portion of the optical envelope of the lamp. In example embodiments, the LEDs can be cooled and/or cushioned by a gas in thermal communication with the LED array to enable the LEDs to maintain an appropriate operating temperature for efficient operation and long life. In some embodiments, the LED assembly is mounted on a glass stem. In some embodiments a thermal resistant path is created that prevents overtemperature of the LED array during the making of the lamp. In some embodiments the LED assembly comprises a lead frame and/or metal core board that is bent into a three-dimensional shape to create a desired light pattern in the enclosure or an extruded submount formed into a three-dimensional shape.
