The utility model for the further technical scheme that solves its technical problem and adopt is:
Preferably, said transparent panel is a kind of in acrylic board, glass plate and the polycarbonate plate.
Preferably, said some leaded light points can be printed in said hyaline membrane and are attached on the one side of said transparent panel or are printed on the one side of said hyaline membrane away from said transparent panel.
Preferably, said some leaded light points are more little from nearlyer its size of led light source.
Preferably, said led light source is a LED lamp bar.
Preferably, said LED lamp bar is provided with at least one or many, and the illuminating part of LED lamp bar is corresponding to the side edge of said transparent panel.
Preferably, said leaded light point is made up of printing ink.
The beneficial effect of the utility model is: the planar LED lamp of the utility model, comprise base, reflecting plate, transparent panel, diffuser plate, led light source and frame, and reflecting plate, transparent panel and diffuser plate are all tabular and are built up the folded structure of an optics successively; The folded structure of optics is positioned on the base in the reflecting plate place, and led light source is positioned at the side edge of transparent panel, and frame is sleeved on the edge of the folded structure of optics and is fixedly connected with base; Hyaline membrane is printed with some leaded light points and is attached at the back side of transparent panel, and the light that led light source sends is injected into transparent panel from side, when light is mapped to each leaded light point that is positioned on the transparent panel back side (being hyaline membrane); Reverberation can be toward all angles diffusion; Destroy conditioned reflex then and penetrate by transparent panel is positive, can line source be converted into area source, reflecting plate can be with in the light reflected back transparent panel; Be used for improving the service efficiency of light; Effectively prevent dazzle through diffuser plate, so the planar LED lamp of the utility model can send even and soft light, and luminous efficiency is high.And for prior art LGP expensive, the utility model is printed in hyaline membrane with the leaded light point and is attached at the technical costs that constitutes light guide structure on the transparent panel lower, and effect is identical.
