Abstract: A compound light source is characterized by an output spectral measure that lies within a spectral measure design range and an average light intensity per component light source that lies within an output intensity design range. The plurality of component light sources includes light sources whose spectral measure value and output intensity lie outside the corresponding design ranges. The component light sources are chosen from a number of predetermined groups obtained by sorting the component light sources with respect to the spectral measure value and output intensity of each source such that the compound light source has a spectral measure value and output intensity that lies within the corresponding design ranges.

Abstract: A light-emitting device capable of being powered by an AC power supply or an unregulated DC power supply is disclosed. The light-emitting device, in an aspect, is coupled to a controller, a light-emitting diode (“LED”) array, and a power supply, wherein the power supply can be an AC power source or an unregulated DC power source. While the power supply provides electrical power, the controller generates various LED control signals in response to power fluctuation of the electrical power. The LED array allows at least a portion of LEDs to be activated in accordance with the logic states of the LED control signals.

Abstract: A light source having first and second LEDs and a phosphor layer that converts light generated by the first LED is disclosed. The first LED emits light at a first wavelength. The layer of phosphor is illuminated by the first LED, the phosphor being excited by light of the first wavelength to convert light of the first wavelength to a band of wavelengths having wavelengths between the first wavelength and a second wavelength. The second LED emits light at a third wavelength that is greater than the first wavelength. The phosphor is not substantially excited by light of the third wavelength. The combined light from the phosphor, and first and second LEDs is perceived as being white by a human observer.

Abstract: A lighting apparatus and method for operating LED-based lighting devices are disclosed. The apparatus includes a receiver that receives a potential from a power source whose output varies as a function of time, an energy storage device, and an LED array. The energy storage device stores energy from the power source when the driving potential is greater than a predetermined value. The LED array has variable forward bias potential, the LED array generating light when a potential across the array is greater than the selected forward bias potential. A source selector connects the energy storage device to the array when the potential from the power source is less than a predetermined value. A controller that varies the forward bias potential such that the difference between the forward bias potential and potential across the array is maintained at a value less than a predetermined value.

Abstract: A mounting fixture for a light-emitting device such as an LED is disclosed. The fixture includes a base having a cavity adapted to receive a module having a light-emitting device mounted thereon, a cover, power contacts that provide electrical connections to the light-emitting device, a spring and a closure. The base has a heat-conducting surface. The cover has a window positioned to allow light from the light-emitting device to pass through the window. The first and second power contacts have first and second portions, respectively, adapted to receive external power connections on an outer surface of the mounting fixture. The spring forces the module against the heat-conducting surface when the base is in a closed position relative to the cover, the module being manually removable from the base when the cover is in an open position relative to the base. The closure reversibly attaches the base to the cover.
