摘要： Light emitting systems are disclosed. The light emitting system includes an electroluminescent device that emits light at a first wavelength from a top surface of the electroluminescent device. The light emitting system further includes a construction proximate a side of the electroluminescent device for blocking light at the first wavelength that would otherwise exit the side. The light emitting system further includes a re-emitting semiconductor construction that includes a II-VI potential well. The re-emitting semiconductor construction receives the first wavelength light that exits the electroluminescent device and converts at least a portion of the received light to light of a second wavelength. The integrated emission intensity of all light at the second wavelength that exit the light emitting system is at least 4 times the integrated emission intensity of all light at the first wavelength that exit the light emitting system.

摘要： An electroluminescent device emits light at a pump wavelength. A first photoluminescent element covers first and second regions of the electroluminescent device and converts at least some of the pump light from the first region of the electroluminescent device to light at a first wavelength. A second photoluminescent element covers the second region of the electroluminescent device without covering the first region of the electroluminescent device and converts at least some of the light of the pump wavelength to light at a second wavelength different from the first wavelength. In some embodiments the first and second photoluminescent elements convert substantially all of the pump light incident from the first and second regions of the electroluminescent device respectively. An etch-stop layer may separate the first and second photoluminescent elements.

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： 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.
