    摘要: A light source comprises an electroluminescent device that generates pump light and a wavelength converter that includes an absorbing element for absorbing at least some of the pump light. A first layer of light emitting elements is positioned proximate the absorbing element for non-radiative transfer of energy from the absorbing element to the light emitting elements. At least some of the light emitting elements are capable of emitting light having a wavelength longer than the wavelength of the pump light. In some embodiments the electroluminescent device is a light emitting diode (LED) that has a doped semiconductor layer positioned between the LED's active layer and the light emitting elements. The first doped semiconductor layer may have a thickness in excess of 20 nm. A second layer of light emitting elements may be positioned for non-radiative energy transfer from the first layer of light emitting elements.

    摘要: Direct-lit backlights and associated methods and components are disclosed in which a transflector that partially transmits and partially reflects incident light is shaped to form at least one concave structure facing a back reflector of the backlight. This provides at least one recycling cavity therebetween, the at least one recycling cavity substantially filling the output area of the backlight. At least one light source is disposed behind the output area to inject light into each cavity, and can be positioned in the recycling cavity or behind an aperture in the back reflector. The cavities are preferably shallow and wide, having a width-to-depth ratio of at least 5 or 10, and can provide uniform brightness and color at the output area with sparsely distributed light sources and in a thin profile backlight.
