Abstract: A package structure of a concentrated photovoltaic cell is provided, wherein a bottom contact of a photovoltaic chip is electrically connected to a metal substrate. The metal substrate not only becomes an external electrode, but also conducts the heat generated by the photovoltaic chip away, providing the function of heat dissipation.

Abstract: In a method for manufacturing a high-brightness planar lamp, a reflecting plate is first provided, and several UV light sources are placed on the reflecting plate. Next, liquid macromolecular polymer is uniformly coated on the reflecting plate and the UV light sources, and fluorescent powder is then uniformly coated on the macromolecular polymer. In another method for manufacturing a high brightness planar lamp, a reflecting plate is first provided, and several UV light sources are placed on the reflecting plate. Next, fluorescent powder and liquid macromolecular polymer are mixed up and uniformly coated on the reflecting plate and the UV light sources. A solidification procedure is then performed. The solidification ways of the mixture of fluorescent powder and macromolecular polymer includes solidification by heating and solidification by illumination of UV light.

Abstract: A modified high-brightness flat lamp structure comprises a reflecting plate, a plurality of UV light sources and a transparent substrate. The reflecting plate has titanium dioxide and macromolecular polymer coated thereon. The transparent substrate has macromolecular polymer and fluorescent powder coated thereon. The UV light sources are arranged in the reflecting plate. The transparent substrate covers the reflecting plate. UV light emitted by the UV light sources and reflected by the reflecting plate will thus excite the fluorescent powder layer to radiate high-brightness visible light.

Abstract: A high-brightness flat lamp structure comprises a reflecting plate, a plurality of UV light sources, a macromolecular polymer layer and a fluorescent powder layer. The UV light sources and the macromolecular polymer layer are sandwiched between the reflecting plate and the fluorescent powder layer. The functions of diffusing and guiding light of the macromolecular polymer layer are exploited to let UV lights emitted by the UV light sources and reflected by the reflecting plate excite the fluorescent powder layer to radiate high-brightness visible lights. Besides, macromolecular polymer and fluorescent powder can be mixed up to form a mixed layer of macromolecular polymer and fluorescent powder to let UV lights emitted by the UV light sources and reflected by the reflecting plate directly excite fluorescent powder to radiate high-brightness visible lights.
