Abstract
The utility model relates to a two-way light conductive plate, which comprises a basal plate and luminous tubes that are arranged at both sides of the basal plate, wherein, a light-reflecting layer which is formed by the vertical and horizontal arrangement of light-reflecting speckles on the surface of the basal plate. The light-reflecting speckles are slightly bulged on the surface of the basal plate, and sparsely arranged at the parts which is adjacent to the luminous tubes at both sides. The light-reflecting speckles gradually get dense toward the central direction, the central part is the most dense region, and the diffuse light reflective brightness of side light can be adjusted thereby. When the utility model is loaded in a lamp housing, the developing area of the light conductive plate is enlarged through two-way light feed, the light brightness emitted by a lamp light source can be maintained uniform and continuous, the developing quality of the lamp housing with large area is improved, and the effects of viewing films become soft, uniform and satisfactory.
Description
The utility model relates to lamp box, the two-way light guide plate in particularly a kind of lamp box.
See in photography in the applications such as sheet, plate making, advertisement exhibition, people need operate by this basic tool of lamp box, and are used to show positive and negative film.Reach in order to guarantee that the lamp sheet shows that color is true to nature, the effect of clear picture, lamp box must have even light, function that colour temperature is correct.
In recent years, the succeeding in developing of ultrathin lamp plate is for market provides easy to carry, correct new tool develops.The core component of ultrathin lamp plate is a light guide plate, and its video picture light source is not the bottom from the display image part, but from display image side partly, introduces light source by light guide plate, thereby reaches the purpose of video picture.The lamp plate of small size can be by unidirection luminous, video picture after the introducing light guide plate, but when the development area increased, unidirectional leaded light video picture just can not have been satisfied the demand.
The purpose of this utility model provides a kind of two-way light guide plate, and it is used for large-area video picture, and it is all even continuous that the luminance brightness that lamp source is sent keeps, and has improved the video picture quality of large tracts of land lamp box.
A kind of two-way light guide plate described in the utility model comprises a substrate, and the luminotron that is provided with in substrate two sides, the surface-coated of described substrate have one deck by reflective spot with the reflector layer that rearranges of row in length and breadth, reflective spot protrudes from the surface of substrate slightly, reflective spot is arranged sparse in the part near two side luminotrons, reflective spot is intensive gradually to center position, to core for compact district, regulate avris diffusion of light glistening intensity thus.
The utility model is packed into behind the lamp box, advance light by two-way, enlarged the video picture area of light guide plate, its reflective spot at the close to sources place place, sparse and distance light source intensive, the light diffusion of light source has obtained adjustment, the light that sends is kept all even continuum of states, has improved the video picture quality of lamp box effectively, makes the sight sheet obtain soft, even, satisfied effect; And reduced lamp house thickness, can be made into slim film viewing light box.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of perspective view of two-way light guide plate.
Fig. 2 is the reflector layer structural representation that above-mentioned two-way light guide plate is coated with reflective spot.
Fig. 3 is the section and the reflective synoptic diagram that moves towards of above-mentioned two-way light guide plate.
Referring to Fig. 1 to Fig. 3, a kind of two-way light guide plate comprises a substrate 1, and the luminotron 2 that is provided with in substrate 1 two sides.The reflector layer that the surface-coated of substrate 1 has one deck to be rearranged by reflective spot 3, reflective spot 3 is arranged in some stringers and walks crosswise.Reflective spot 3 protrudes from the surface of substrate 1 slightly.Reflective spot 3 is according to the far and near distance setting of light source, arranging sparsely near the part of two side luminotrons 2, makes strong light see through the space of reflective spot 3 and sieves a part of light; Reflective spot 3 is intensive gradually to center position, is compact district to core, thereby luminance brightness away from light source is kept and strengthens to some extent.Reflective spot 3 so is provided with the just diffusion glistening intensity of adjustable side sidelight.
The reflective spot 3 of substrate 1 surface-coated is a circular spot, sees shown in the figure.The reflective spot 3 of substrate 1 surface-coated also can be square spot, perhaps is irregularly shaped spot.
The one side of the substrate 1 of the two-way light guide plate of the utility model applies the reflector layer that one deck is made up of reflective spot 3, the another side installing diffusion paper 4 of substrate 1.On two-way light guide plate and the luminotron 2 reflex housing 5 is housed also.
The reflective spot of reflector layer is coated on substrate surface with screen printing mode with white paint in the utility model, is adjusted into soft, uniform light with the light that light source is sent, and makes the sight sheet obtain soft, even, satisfied effect.
Claims (4)
1. two-way light guide plate, it comprises a substrate, and the luminotron that is provided with in substrate two sides, it is characterized in that, the surface-coated of described substrate have one deck by reflective spot with the reflector layer that rearranges of row in length and breadth, reflective spot protrudes from the surface of substrate slightly, reflective spot is arranged sparse in the part near two side luminotrons, reflective spot is intensive gradually to center position, to core for compact district, regulate avris diffusion of light glistening intensity thus.
2. two-way light guide plate according to claim 1 is characterized in that, the reflective spot that described substrate surface applies is a circular spot.
3. two-way light guide plate according to claim 1 is characterized in that, the reflective spot that described substrate surface applies is square spot.
