Lighting Guide Plate of Panel Light Analysis

Lighting Guide Plate of Panel Light

There are three kinds of Lighting Guide Plate (LGP) used in LED panel light. carving LGP, silk printing LGP and nano LGP.

Carving LGP is according to the different size, engraving on the transparent sheet of mesh grid lines. Using the refraction of grid lines produces diffuse light, making point light source to an area light source.

Silk printing LGOP is according to a certain size, printing reflective outlets on the transparent sheet. Use of printing ink dots to produce diffuse light, change point light source to the plane light source.

Carving LGP, silk printing LGP, the light points density must be according to the size. And these two technologies are difficult to make personal design. Can not be arbitrary cutting, hot bending. At the same time, must be equipped with a diffuser plate when fix in LED panel light, cannot be used double-sided.

Disadvantages: The carving, printing point or line where the visual impact is bigger, will be a little light and shade, not the exact uniform surface. Silk printed with ink dot, so there is light failure phenomenon.

Nano LGP, the making method is add the nanoscale grade light scattering particles when molding the LPG. The nanoparticles point light source or lines sources can be efficiently converted into uniform plane light source.

On the basis of the original nano plate can be arbitrary cutting, hot bending, can be double side use. Can not come with a diffuser plate. Can be made different original mold to cast light of any shape and widely applicable. But not suitable for the crystal light box, because his whole transparency not good enough.
