摘要:
A light source device includes a LED light source or a wavelength conversion material having a near Lambertian light emitting surface. The light source device includes a light recycling system to reflect small-angle lights (lights closer to the normal direction of the light emitting surface) back to the light source, and a collection system for collecting and outputting large-angle lights (lights farther away from the normal direction). The lights reflected by the light recycling system is scattered by the emitting surface in all directions, where the large-angle scattered lights are collected by the light collection system and the small-angle scattered light is reflected by the light recycling system again. A second excitation light source without wavelength conversion material or a second light source with its own wavelength conversion material may be provided, and the second light is directed to the light emitting surface by appropriate optical components.

An embodiment of a lighting system for illuminating an environment with a lighting that simulates natural lighting includes: a first light source which emits a beam of visible light; a diffused-light generator delimited by an inner surface, which receives the light beam, and an outer surface, the diffused-light generator being at least partially transparent to the light beam. The diffused-light generator transmits at least part of the light beam and emits, through the outer surface, visible diffused light, the correlated color temperature of the transmitted light being lower than the CCT of the visible diffused light. The lighting system includes a dark box which hosts the first light source, the dark box being optically coupled to the environment via the diffused-light generator.

In the conventional lighting equipment for vehicle using LED lamp, as the LED lamp irradiation angle is narrow, an optical irregularity making the luminescent surface spotted is generated, resulting in a feeling of wrongness of the viewer. Means to Solve the Problem. A LED lighting equipment 1 for vehicle of the present invention, comprising at least one light emitting unit 3 wherein an LED lamp 2 is disposed approximately at the focus of one hyperboloid, a reflection surface of hyperboloid 4 defined by the other hyperboloid comprising a transmission portion 4a disposed in an appropriate range near the optical axis is arranged in the LED lamp 2 optical axial direction, and a refection surface of paraboloid of revolution 5 having the approximate focus at the focus of said the other hyperboloid focus is arranged at the side of said LED lamp 2, allows to enlarge the irradiation angle at the reflection surface of hyperboloid 4, and to emit light in a larger area.
