Abstract
The utility model belongs to the technical field of electric light sources, and relates to an organic glass display screen using a cold cathode fluorescence lamp as a light source. A cold cathode lamp tube is attached in a groove at one side edge of a glass sheet, and takes the side edge as a bracket. Because the tube diameter of the lamp tube is generally less than the thickness of the glass sheet, utilance can be enhanced; the waste of energy resources can be avoided. Furthermore, the light rays of the lamp tube can not directly irradiate planes at both sides of the glass sheet; thus, the contrast grade of irradiation is enhanced; the display definition of letters or patterns carved on the glass sheet is improved. The display screen can be used as a billboard, an indication board, etc., and can also be used as an indoor or outdoor ornament to beautify living environment.
Description
The utility model belongs to the electric light source technology field, is a kind of organic glass display screen that adopts cold cathode luminous source.
Organic glass has good optical characteristics, is widely used in many special lighting occasions.As avigation light, utilize the light transmission and the refractivity of organic glass exactly, by the irradiation of light source on poly (methyl methacrylate) plate (display screen) one side, demonstrate the literal that is engraved on the organic glass board plane or pattern etc.At present, this organic glass display screen adopts common hot-cathode fluorescent lamp as radiation source usually.Because the restriction of filament volume in hot-cathode fluorescent lamp is managed, caliber can not be done very carefully, generally all more than 10mm.And the organic glass plate thickness so two side planes of display screen also can be subjected to light source irradiation, has so just reduced the contrast of display plane usually less than the caliber of fluorescent tube, thereby influences the display resolution of literal or pattern.In addition, because the caliber of fluorescent tube is thicker, very most light is not used effectively, and causes the waste of the energy.
The purpose of this utility model is to propose a kind of literal and pattern displaying sharpness of both can having improved, and can avoid the organic glass display screen of energy dissipation again.
The organic glass display screen of the utility model design is made of poly (methyl methacrylate) plate, lighting source, supply convertor and lamp bracket, is carved with literal and/or pattern etc. on the poly (methyl methacrylate) plate.Wherein, lighting source adopts ultra-fine cold-cathode fluorescence lamp, and its caliber is 2-4mm, and fluorescent tube fits in the groove of poly (methyl methacrylate) plate one side, and is support with this side.Lamp bracket is arranged at the fluorescent tube upside, and supply convertor is arranged at the lamp bracket the inside.As depicted in figs. 1 and 2.
In the utility model, display screen can be a single layer structure, also can be multilayer structure.During single layer structure, poly (methyl methacrylate) plate is one.During composite structure, poly (methyl methacrylate) plate can be divided into the bottom plate and the surface layer plate is two-layer, and bottom plate back scribbles the reflection horizon, and literal and/or pattern can to form ray refraction, can be carved with on the surface layer plate for analysing the prismatic formula in the front.Bottom plate and surface layer plate can be fixed with frame.The display screen of multilayer structure makes pattern or literal more be rich in stereoscopic sensation.
The organic glass display screen of the utility model design, owing to used the cold-cathode fluorescence lamp of superfine pipe diameter as radiation source, the caliber of fluorescent tube is less than the thickness of poly (methyl methacrylate) plate, its light can all impinge upon on the side of glass plate and be fully utilized, improve utilance, avoided the waste of the energy.And the light of fluorescent tube can not shine directly on two side planes of poly (methyl methacrylate) plate, thereby can increase substantially the contrast of display plane, and the literal on the plane or the sharpness of pattern are greatly improved.In addition, ultra-fine fluorescent tube integral body directly with poly (methyl methacrylate) plate itself as fixed support, avoided having save the relevant structure member of lamp again because of the too thin drawback of fracture easily of caliber, reduced cost of products.Because the cold-cathode fluorescence lamp long service life, low in energy consumption, brightness is high, and the performance of entire display screen is improved a lot than existing similar display screen.The utility model can be made into the specification and the different shape of different sizes as required.Can be used as billboard, index board etc.Also can be used as the ornament of indoor and outdoor, beautify the living environment.
Fig. 1 is the utility model structural diagrams.Fig. 2 is multilayer structure display screen diagram.
Label wherein: 1 poly (methyl methacrylate) plate, bottom plate when the 1-1 poly (methyl methacrylate) plate is multilayer structure, 1-2 is the surface layer plate that is carved with pattern and/or literal, 1-3 is the reflector layer of bottom plate, 2 ultra-fine cathode fluorescent tubes, 3 lamp brackets, 4 supply convertors, literal on the 5 organic glass board planes is or/and pattern, and 6 is the frame of multilayer structure.
Embodiment: as shown in Figure 1, poly (methyl methacrylate) plate 1 thickness is 5mm, and size is 350 * 200mm, is carved with literal and pattern 5 on its face.The two ends of its upper side edge are provided with fluorescent tube bayonet socket and lamp bracket fixture.Cathode fluorescent tube 2 diameter 2.6mm, length 300mm, its two end electrodes is inserted bayonet socket.Lamp bracket 3 adopts metal or plastic products, fixes with the fixture at glass plate upside two ends, and supply convertor 4 is arranged at gallery 3 inside, connects the lead of lamp, promptly gets required organic glass display screen.
