1. A modified high-brightness flat lamp structure comprising:
- a reflecting plate having a cavity formed therein, said cavity having a longitudinally extended bottom wall bounded by a plurality of sidewalls with titanium dioxide and a macromolecular polymer coated thereon;
a plurality of UV light sources disposed in said cavity in side by side longitudinally spaced relationship; and
, a transparent substrate having opposing inner and outer walls, said inner wall being disposed in overlaying relationship with said reflecting plate, said transparent substrate forming a closure for said cavity and being coated with a macromolecular polymer and fluorescent powder, wherein UV light emitted by said UV light sources is reflected by said reflecting plate for exciting said fluorescent powder to radiate high-brightness visible light from said outer wall of said transparent substrate.

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.
