摘要： Light emitting systems are disclosed. The light emitting system emits an output light that has a first color. The light emitting system includes a first electroluminescent device that emits light at a first wavelength in response to a first signal. The first wavelength is substantially independent of the first signal. The intensity of the emitted first wavelength light is substantially proportional to the first signal. The light emitting system further includes a first luminescent element that includes a second electroluminescent device and a first light converting layer. The second electroluminescent device emits light at a second wavelength in response to a second signal. The first light converting layer includes a semiconductor potential well and converts at least a portion of light at the second wavelength to light at a third wavelength that is longer than the second wavelength. The light emitting system combines light at the first wavelength with light at the third wavelength to form the output light at the first color. When one of the first and second signals changes from about 50% of a maximum rating of the signal to about 100% of the maximum rating, but the ratio of the first signal to the second signal remains substantially unchanged, the first color of the output light remains substantially unchanged.

摘要： An arrangement of light sources is attached to a semiconductor wavelength converter. Each light source emits light at a respective peak wavelength, and the arrangement of light sources is characterized by a first range of peak wavelengths. The semiconductor wavelength converter is characterized by a second range of peak wavelengths when pumped by the arrangement of light sources. The second range of peak wavelengths is narrower than the first range of peak wavelengths. The semiconductor wavelength converter is characterized by an absorption edge having a wavelength longer than the longest peak wavelength of the light sources. The wavelength converter may also be used for reducing the wavelength variation in the output from an extended light source.

摘要： Re-emitting semiconductor constructions (RSCs) for use with LEDs, and related devices, systems, and methods are disclosed. A method of fabrication includes providing a semiconductor substrate, forming on a first side of the substrate a semiconductor layer stack, attaching a carrier window to the stack, and removing the substrate after the attaching step. The stack includes an active region adapted to convert light at a first wavelength λ1 to visible light at a second wavelength λ2, the active region including at least a first potential well. The attaching step is carried out such that the stack is disposed between the substrate and the carrier window, which is transparent to the second wavelength λ2. The carrier window may also have a lateral dimension greater than that of the stack. The removal step is carried out so as to provide an RSC carrier device that includes the carrier window and the stack.
