摘要： A light source and method for making the same are disclosed. The light source includes a substrate and a light emitting structure that is deposited on the substrate. A barrier divides the light emitting structure into first and second segments that are electrically isolated from one another. A serial connection electrode connects the first segment in series with the second segment. A first blocking diode between the light emitting structure and the substrate prevents current from flowing between the light emitting structure and the substrate when the light emitting structure is emitting light. The barrier extends through the light emitting structure into the first blocking diode.

摘要： A light source having a substrate with a plurality of component LED light generators mounted thereon is disclosed. The substrate has a first metallic surface characterized by a normal that points in a normal direction. The first metallic surface is in contact with air over the first metallic surface. The component LED light generators are mounted directly on the first metallic surface. Each component LED light generator includes an LED characterized by an operating temperature and emitting light in the normal direction. Each LED generator generates more than 0.5 watts of heat. The component LED light generators are spaced apart on the first metallic surface such that the operating temperature remains less than 75° C. above the air temperature. In one aspect of the invention, the first metallic surface surrounding each component LED light generator radiates an amount of heat equal to the heat generated by that component LED light generator.

摘要： A light source and method for making the same are disclosed. The light source includes a plurality of Segmented LEDs connected in parallel to a power bus and a controller. The power bus accepts a variable number of Segmented LEDs. The controller receives AC power and provides a power signal on the power bus. Each Segmented LED is characterized by a driving voltage that is greater than 3 times the driving voltage of a conventional LED fabricated in the same material system as the Segmented LED. The number of Segmented LEDs in the light source is chosen to compensate for variations in the light output of individual Segmented LEDs introduced by the manufacturing process.

摘要： An LED-based lighting device and method for making the same are disclosed. The lighting device includes an LED light source mounted on a heat sink, a power adaptor, and a controller. The power adaptor is configured to be interchangeable with a conventional incandescent bulb power adapter. The controller provides an average current to the LED light source when power is coupled to the device via the power adaptor. The average current causes the LED light source to generate light of a predetermined standard intensity that is substantially independent of variations in the LED light source from device to device. In one aspect of the invention, the LED light source includes a plurality of LEDs connected in series, the LEDs are bonded to the heat sink and connected to one another in series by wire bonds and to conducting traces on the heat sink.
