Embodiment Construction
[0014] In the following, the embodiments of the present invention will be further described in detail with reference to the accompanying drawings.
[0015] See figure 1 , A lighting device 10 provided by the first embodiment of the present invention includes a light-permeable substrate 11, a plurality of solid-state light sources 13, and a solar cell 15.
[0016] The substrate 11 may be a rectangular structure, which includes a bottom surface 110, at least one light incident surface 112 intersecting the bottom surface 110, and a light exit surface 114 opposite to the bottom surface 110. In this embodiment, the rectangular structure has four light incident surfaces 112. The substrate 11 can transmit light, and it can be a glass substrate. Of course, the substrate 11 can also be made of other transparent plastics, such as PMMA (Polymethylmethacrylate), PC (Poly Carbonate), silicone, etc.
[0017] The multiple solid-state light sources 13 are optically coupled with the substrate 11,...

Abstract
The invention relates to an illuminating device, which comprises a light-transmission substrate, a plurality of solid state light sources and at least one solar battery, wherein the substrate comprises a bottom surface, at least one incident surface crossed with the bottom surface and an emergence surface opposite to the bottom surface; the plurality of the solid state light sources are arranged opposite to the at least one incident surface of the substrate, and light rays transmitted by the plurality of the solid state light sources are incident on the substrate by the at least one incident surface and emitted from the emergence surface of the substrate; and the at least one solar battery is arranged opposite to the bottom surface of the substrate and is used for absorbing sunlight and converting the solar energy into electrical energy so as to provide power to the plurality of the solid state light sources. The illuminating device can provide illumination and lighting for buildings.
Description
Technical field [0001] The present invention relates to a lighting device, in particular to a lighting device using light-emitting diodes as light-emitting elements. Background technique [0002] At present, light emitting diodes (LEDs) are gradually replacing existing fluorescent lamps or incandescent lamps as light emitting elements of lighting devices due to their advantages of small size, high efficiency, and long life, so as to save power and reduce waste of resources. For details, please refer to the article "Solid-State Lighting: Toward Superior Illumination" published by Michael S. Shur et al. in the document Proceedings of the IEEE, Vol. 93, No. 10 (October 2005). [0003] On the other hand, with the increasingly tense world energy problem, solar energy as a clean and inexhaustible energy source has received more and more attention, transforming solar energy into energy that people can use, such as electric energy. In the prior art, it is usually realized by solar cells....
