Abstract
The utility model relates to a unidirectional light uniforming plate for lamp boxes. A fluorescent tube and a lamp cover are arranged on an edge of one side of the plate. The base material of the light uniforming plate is a sub-gusset plate. The lower surface of the plate is coated with a layer of light reflecting layer. A thinnest layer of the light reflecting layer is arranged near a start point of a light source. A thickest layer is arranged two thirds of the light source away. The thinnest layer is regained when an end point of the light source is reached. The other side surface of the light uniforming plate is coated with a layer of reflecting layer. The diffusion of light rays of the light source is adjusted after the unidirectional light uniforming plate for lamp boxes is arranged inside the lamp box. The uniform and continuous state of the emitted light is kept. The soft, uniform, and satisfying effect is obtained for a viewed film.
Description
The utility model relates to lamp box, the unidirectional even tabula rasa of 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.For many years, most lamp boxes all adopt fluorescent tube as the video picture light source, and fluorescent light is cheap, and it is convenient to change, so it continues as basic luminaire.But fluorescent tube has its intrinsic disadvantage, promptly lights constantly flicker of back, as directly placing below the video picture panel, then exists non-uniform light all the time in lamp box, even local phenomenon of developing occurs.
The purpose of this utility model provides the unidirectional even tabula rasa of a kind of new lamp box, and it is all even continuous that the luminosity that it sends fluorescent light keeps, and has improved the video picture quality of lamp box.
The unidirectional even tabula rasa of a kind of lamp box described in the utility model, fluorescent tube and lampshade are installed by a lateral edges place at this plate, the base material of described even tabula rasa is the polymethyl methacrylate plate, the lower surface of this plate is coated with one deck reflector layer, this reflector layer near the starting point of light source for thin layer, be thickest layer to 2/3 place apart from light source, arrival reverts to thin layer apart from the destination county of light source, be reflector layer by thin layer to thickest layer, return to thin layer by thickest layer again; The opposite side surface-coated of described even tabula rasa has one deck reflection horizon.
The utility model is packed into behind the lamp box, and the light diffusion of light source has obtained adjustment, and the light that sends is kept all even continuum of states, has improved the video picture quality of lamp box effectively, makes to see sheet and obtain soft, even, satisfied effect.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is the structural representation of the unidirectional even tabula rasa of a kind of lamp box.
Referring to accompanying drawing, the unidirectional even tabula rasa of a kind of lamp box is installed fluorescent tube 1 and lampshade 2 at a lateral edges place of this plate.The base material of even tabula rasa is a polymethyl methacrylate plate 3, and the lower surface of this plate applies one deck reflector layer 4.This reflector layer 4 near the starting point 5 of fluorescent tube 1 for thin layer, be thickest layer to 2/3 place 6 apart from fluorescent tube 1, arrival reverts to thin layer apart from the destination county 7 of fluorescent tube 1.That is to say that reflector layer 4 to thickest layer, returns to thin layer by thickest layer by thin layer again.Opposite side surface-coated one deck reflection horizon 8 of even tabula rasa.
Source light imports from a side of even tabula rasa, under positive luminous and the effect that the back is reflective of light source, spare the tabula rasa diffusion from the side of even tabula rasa to monoblock, the reflector layer 4 of even tabula rasa along with the distance of light source from shallow to deep, to apart from light source 2/3 place for the darkest, from deep to shallow subsequently, when arrive sparing the opposite side reflection horizon 8 of tabula rasa, reflector layer 4 returns to the light color at starting point place, promptly thin layer.
The diffused ray that imports from even tabula rasa side with a part of highlights elimination, and during away from light emitting source, is maintained light intensity by the reflector layer of deepening 4 at diffused ray by reflector layer 4 when entering even tabula rasa.At the opposite side of even tabula rasa, because reflection horizon 8 is the frosted shape, its reflection has strengthened light intensity, so reflector layer 4 returns to the light color at starting point place, with unnecessary highlights elimination.
The Lights section in the utility model can adopt existing fluorescent light, also can adopt cold cathode, energy-saving pipe luminophor.
Reflector layer 4 in the utility model and reflection horizon 8 are coated on even tabula rasa substrate surface with screen printing mode with white paint, are adjusted into soft, uniform light with the light that light source is sent.
Claims (1)
1. unidirectional even tabula rasa of lamp box, fluorescent tube and lampshade are installed by a lateral edges place at this plate, it is characterized in that, the base material of described even tabula rasa is the polymethyl methacrylate plate, and the lower surface of this plate is coated with one deck reflector layer, and this reflector layer is from being thin layer near the starting point of light source, to 2/3 place apart from light source is thickest layer, arrival reverts to thin layer apart from the destination county of light source, and promptly reflector layer to thickest layer, returns to thin layer by thickest layer by thin layer again; The opposite side surface-coated of described even tabula rasa has one deck reflection horizon.
