Abstract: An illumination system includes a solid-state light-emitting element and a wavelength-converting device. A first waveband light is emitted to an optical path by the solid-state light-emitting element. The wavelength-converting device is disposed on the optical path and includes a phosphor plate. The phosphor plate is a solid mixture having a phosphor agent and a binder. The weight percent of the phosphor agent is from 10 to 70, such that the first waveband light is transformed into a second waveband light. Under this circumstance, the efficiency of heat conduction of the phosphor plate is effectively enhanced, thereby enhancing the converting efficiency of the wavelength-converting device, which is strong enough to be applied to rotate with great rigidity. Meanwhile, not only the space requirement is reduced, but also the phenomena of hot spot and heat diffusion are avoided, such that the cost and difficulty of manufacturing the wavelength-converting device are significantly reduced.

Abstract: The present invention is directed toward a lighting device in a motor vehicle that includes a first light conductor and at least one second light conductor. The first light conductor propagates light by total internal reflection which impacts on a light coupling-out area of light conductor and is at least partially reflected toward and emits from an opposite light output area. The at least one second light conductor propagates light by total internal reflection which is coupled into the first light conductor by a midway coupling-in. The light that emits out of the second light conductor via a light output area enters into the first light conductor via the light coupling-out area. An air gap is formed between the light coupling-out area of the first light conductor and the light output area of the second light conductor.
