TL;DR: In this article, a lens (240) containing a fluorescent dye is over molded to a short wavelength light emitter (110), such as a blue LED or laser diode placed within a reflector cup (120).

TL;DR: An improved sensor array and illumination scheme for a bar code scanner use a modified Scheimpflug arrangement optical system that simplifies signal processing as discussed by the authors, and the preferred embodiment includes a detector array (131) comprising a multi-element array of photosensors (311) positioned in one Scheim pflug plane (141) and an illumination beam in the form of a sheet of light along the other Scheim Pflug planes (119).

TL;DR: An optical display system includes a light source, a color wheel, an optical train and a light valve as mentioned in this paper, which is used to fill in holes in the cone half-angle distribution of light generated by the light source.

TL;DR: A light emitting device comprises a flip-chip light emitting diode (LED) die mounted on a submount The top surface of the submount has a reflective layer over the LED die is molded a hemispherical first transparent layer to provide TIR of phosphor light.

TL;DR: A light source assembly and method of providing illumination a target surface utilize a fluorescent material to generate composite "white" light from source light of a particular color, i.e., a particular wavelength as mentioned in this paper.
