    摘要: A lighting device provides a spectrally-shifted light output from a light source. The lighting device includes a semiconductor light emitting device providing a source light and a first thin-film luminescent material layer coating a surface of the semiconductor light emitting device. The first thin-film luminescent material layer includes a luminescent material that emits an emitted light in response to the source light. The first thin-film luminescent material layer has a specific and consistent thickness and specific and consistent density of luminescent particles. The emitted light includes a first luminescent material emitted light when the luminescent material completely absorbs the source light. The emitted light includes a first composite light when the first luminescent material absorbs less than all of the source light. The device may further include a second thin-film luminescent layer coating the first thin-film luminescent layer.

    摘要: An encoder having a code carrier, light source, and detector is disclosed. The code carrier includes a track that emits light at each of a plurality of track points on the track when that track point is illuminated with light having a predetermined spectrum. Each of the track points emits light having a spectrum that is different from the spectrum emitted by others of the track points. The light source illuminates a portion of the track with light of the predetermined illumination spectrum. The detector provides a plurality of signals indicative of the spectrum of light leaving the portion of the track when the portion includes one of the track points. The code carrier moves with respect to the detector, and the signals define the relative position of the code carrier with respect to the detector.

    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.
