摘要： A light emitting sign comprising a light emitting display surface including at least one phosphor, and at least one radiation source configured to irradiate the display surface with excitation energy such that the phosphor emits light of a selected color. The sign further comprises a filter which is substantially transparent to light emitted by the display surface, filtering other colors of light. The display surface may be configured into a shape of a character, a symbol, or a device. Alternatively, a mask having at least one window substantially transparent to the emitted light and/or at least one light blocking region may be provided in which the window and/or light blocking region define a character, a symbol, or a device.

摘要： A light source comprises a blue emitting LED operable to generate blue excitation light and a light emitting surface comprising a light transmissive substrate and a phosphor. The LED is configured to irradiate the light emitting surface with excitation light such that the phosphor emits light of a second wavelength and wherein light emitted by the source comprises a combination of blue light from the LED and the second wavelength light from the phosphor. The light emitting surface is interchangeable thereby enabling the source to generate different selected colors of light using the same LED. The phosphor can be provided as a layer on the substrate or incorporated within the light transmissive substrate. The light emitting surface can be configured as a waveguide or as a light transmissive window.

摘要： Disclosed herein are “smart” phosphor compositions capable of regulating the chromaticity of their emission to substantially constant values even with variations in the excitation radiation they receive to induce photoluminescence. One phosphor of the smart composition demonstrates an increase in emission intensity increases as the wavelength of the excitation radiation is increased. The other phosphor shows a decrease in emission intensity with increasing excitation wavelength. Constant chromaticity in this context is defined as a change in CIE x or y coordinate of less than about five percent over a 10 nm range of excitation wavelengths.
