Design we fully use the photosource in Super thin light in the box, because we have a piece of extremely special principle Light the Guide plate, it is uses Huygens-Fresnel the principle manufacture, therefore that Super thin light box design all demands the energy conservation, brightness is decided by the luminous flux intensity. So we own research and develop the wavelet Newton's rings principle to carry on the light interference craft, in optics principle the Fresnel confirms only then the wavelet only then to have the energy to push the light far, therefore lets the light by ∮ 2.8mm 8.8W CCFL march forward reaches 620mm all to be able the very even distribution in each place, The illuminance also can achieve 1200LUX also Light Guide 4mm is only thick, lamp box total thickness smallest 6mm only then the American ADAAG 4.4.1 standards 1,/17, far surpass the various countries no matter what a standard
