In this article, a solid-state light source includes a semiconductor light source for emitting light and an optical system having a fiber optic element for receiving emitted light from the light source.Abstract:
A solid-state light source includes a semiconductor light source for emitting light and an optical system having a fiber optic element. The fiber optic element has an input for receiving emitted light from the semiconductor light source. The fiber optic element also has an output for emitting light received from the solid-state light source. The semiconductor light source and the fiber optic element in aggregate form an illumination path.read more

Light Emitting Device
TL;DR: By doping an organic compound functioning as an electron donor (hereinafter referred to as donor molecules) into an organics layer contacting a cathode, donor levels can be formed between respective LUMO (lowest unoccupied molecular orbital) levels between the cathode and the organic compound layer, and therefore electrons can be injected from the cathodes, and transmission of the injected electrons can also be performed with good efficiency as discussed by the authors.
