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. In another aspect of the invention, the number of Segmented LEDs connected to the power bus can be altered after the light source is assembled.

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 emitting device, a wafer for making the same, and method for fabricating the same are disclosed. The device and wafer include a first layer of a first conductivity type, an active layer, and a layer of a second conductivity type. The active layer overlies the first layer, the active layer generating light. The second layer overlies the active layer, the second layer having a first surface in contact adjacent to the active layer and a second surface having a surface that includes features that scatter light striking the second surface. A layer of transparent electrically conducting material is adjacent to the second surface and covered by a first layer of a dielectric material that is transparent to the light generated by the active layer. A mirror layer that has a reflectivity greater than 90 percent is deposited on the first layer of dielectric material.

摘要： A light source and method for making the same are disclosed. The light source includes a housing, a drive assembly, and an LED. The housing has an interior compartment enclosed in an outer surface having a heat dissipating surface and first and second power terminals that are accessible from outside the interior compartment. The drive assembly is located in the interior compartment and electrically connected to the first and second power terminal. The LED is directly attached to the heat dissipating surface and electrically insulated therefrom, the LED having first and second LED power contacts. The housing has first and second housing power terminals disposed outside the housing, electrically isolated from the heat-dissipating surface, and connected to the drive assembly. A first conductor connects the first LED power contact to the first housing power terminal. A second conductor connects the LED second power contact to the second housing power terminal.
