The utility model for the further technical scheme that solves its technical problem and adopt is:
Preferably, the front of said glass plate can be the frosting that after polishing is handled, forms, and also can be the beautiful sand face that after liquid medicine corrodes, forms.
Preferably, said some leaded light points are printed in that said hyaline membrane is attached at the one side of said glass plate or away from the one side of said glass plate.
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 one or more, and the illuminating part of LED lamp bar is corresponding to the side edge of said glass plate.
Preferably, said leaded light point is made up of printing ink.
The beneficial effect of the utility model is: the plate LED lamp of the utility model, comprise base, reflecting plate, glass plate, led light source and frame, and reflecting plate and glass plate are all tabular and are superimposed with each other and form the folded structure of an optics and be positioned on the base; Led light source is positioned at the side edge of glass plate, and frame is sleeved on the edge of the folded structure of optics and is fixedly connected with base, and hyaline membrane is printed with some leaded light points and is attached at the back side of glass plate; The front of glass plate is rough rough surface, and the light that led light source sends is injected into glass plate from side, when light is mapped to each leaded light point that is positioned on the glass plate back side (being hyaline membrane); Reverberation can be toward all angles diffusion; Destroy conditioned reflex then and penetrate, can line source be converted into area source, in the light reflected back glass plate that reflecting plate can expose the glass plate bottom by glass plate is positive; Be used for improving the service efficiency of light; Because the front of glass plate is rough rough surface, therefore can effectively prevent dazzle, substituted traditional diffuser plate; Therefore the plate LED lamp of the utility model can send even and soft light, and luminous efficiency is high.And for prior art adopts diffuser plate and acrylic material LGP expensive; The utility model adopts the hyaline membrane that is printed with leaded light point to be attached at glass plate and forms LGP; And the glass plate front has light diffusion function simultaneously, so cost is lower and simplify the structure.
