The light emitting elements are capable of emitting light at a second wavelength different from the first wavelength. In some embodiments a grid electrode (213) is disposed on the first doped semiconductor layer and defines open regions (214) of a surface of the first doped layer, the first plurality of light emitting elements being positioned in the open regions.

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： A phosphor tape article includes a phosphor layer having a phosphor and a polymeric binder material, a pressure sensitive adhesive layer disposed adjacent the phosphor layer such that light transmitted through the pressure sensitive adhesive layer is received by the phosphor layer, and a release liner disposed on the pressure sensitive adhesive layer. The pressure sensitive adhesive layer is disposed between the release liner and the phosphor layer. The phosphor is suitable for excitation by UV or blue LED light, and the phosphor emission has a characteristic decay rate of less than 1 second. Light emitting devices including pieces of phosphor tape, and methods of making such devices, are also disclosed.
