    摘要： A two-terminal light-emitting diode (“LED”) device has a first terminal and a second terminal, and a first color LED and a second color LED. An intensity control device is coupled to the first color LED and a control circuit controls the intensity control device so as to produce a selected light intensity from the first color LED according to a control signal provided to the first terminal. The control signal also provides electrical power to the first color LED and to the second color LED.

    摘要： An apparatus having a light source, light pipe, and light conversion layer is disclosed. The light source includes a plurality of LED dies arranged in an array, each LED emitting light having an excitation wavelength, the light source emitting light within a cone of angles. The light pipe is positioned to receive the light within the cone of angles through an edge surface such that the light within the predetermined cone of angles is totally reflected from the top surface. The light pipe has features that redirect some of the light at angles such that some of the redirected light exits through the top surface. The light conversion layer overlies the top surface and converts light of the excitation wavelength to light in an output spectrum having wavelengths different from the excitation wavelength. A display layer can be placed such that it is illuminated by light from the light pipe.

    摘要： A phosphor composition and a light source constructed therefrom are disclosed. The phosphor composition includes first and second phosphors. The first phosphor includes first phosphor particles that convert light of an excitation wavelength to light having a first spectrum characterized by an intensity of light that varies as a function of wavelength. The first phosphor particles are chosen such that the first spectrum is independent of the size of the particles. The second phosphor includes particles of a QD phosphor that convert the excitation light to light in a QD phosphor spectrum. The first phosphor particles and the QD phosphor particles are present in a ratio of concentrations. The ratio, the first phosphor particles, and the QD phosphor particles are chosen such that a combined spectrum has an intensity that is more uniform as a function of wavelength than either the QD phosphor spectrum or the first spectrum.

    摘要： In one embodiment, apparatus is provided with a display panel, a wavelength converting material, and a light source. The display panel is provided with an interface to receive control signals defining one or more primary images that are projected from the display panel. The wavelength converting material absorbs light of a first wavelength and emits light of a second wavelength. The wavelength converting material defines a secondary image that is projected from the display panel when the wavelength converting material is illuminated by the light of the first wavelength. The light source causes the wavelength converting material to be illuminated by the light of the first wavelength.

    摘要： A handheld fluorescence detector that includes a handheld data processing system and a UV light source connected to the data processing system is disclosed. The UV light source illuminates an object to be scanned with light having a UV illumination wavelength. A safety mechanism inhibits the light from the UV light source from reaching an eye of a person in the vicinity of the UV light source at an intensity that would damage the eye. A fluorescence detector senses fluorescent light generated by the object in response to the illumination. The fluorescence detection can utilize a photodetector or a human observer. The detector can be included in a cellular telephone or PDA. Safety mechanisms that utilize baffles or total internal reflection to protect the user are described. In addition, interlock mechanisms that prevent the UV light source from being activated when no object is present can be incorporated.
