Abstract
The utility model relates to a thin and planar lamp box, which is characterized in that two lighting strip lamps are arranged parallelly on both sides of a box body. Two light conducting plates which are made of a plurality of layers of materials with a high light transmittance and is stuck in equidistant trapezoidal area and in a staircase shape are arranged slantwise in front of a reflecting base plate between the lighting strip lamps. Advertisement words and patterns are drawn on a light transmission panel of the lamp box. The thin and planar lamp box has the advantage that because light which is emitted from the lighting strip lamps is reflected on the light transmission panel of the lamp box by the light conducting plate, the number of the lighting strip lamps required by the lamp box is fewer. The thickness of the box body can be reduced. The brightness of the light transmission panel of the lamp box is enhanced. The illuminance is uniform. The thin and planar lamp box is suitable for the display of common commercial advertisements, luminous word and pattern marks, and lighting fixtures.
Description
The utility model belongs to lighting device, particularly a kind of thin, planar lamp box that the picture-text advertisement sign of illumination is arranged.
Existing advertising lamp box is at the advertising design back side lamp box to be set, and inside is set up in parallel many fluorescent tubes, to illuminate the pattern and character of lamp house panel, forms luminous advertisement.Its casing thickness is bigger, and fluorescent tube quantity is more, just can obtain literal, pattern even brightness effect.
The purpose of this utility model is to design and produce a kind of thin, planar lamp box, the light that adopts light guide plate polymerization fluorescent tube to send, reflex on the lamp house panel through reflector, to reduce fluorescent tube quantity and lamp house thickness, improve irradiation brightness, reach energy-conservation and the even brightness effect.
Thin, planar lamp box of the present utility model, by casing, the in-built lighting fluorescent tube, reflective base plate, light penetrating panel is formed, and it is characterized in that, two illuminating lamp tubes be arranged in parallel in the casing both sides, between the illuminating lamp tube, reflective base plate the place ahead, oblique be provided with two by multilayer high transmission rate material, be the light guide plate that the stepped applying of equidistant tread forms, be painted with literal, pattern on the lamp box light penetrating panel.
Light guide plate can be made by glass plate or poly (methyl methacrylate) plate.
Principle of work of the present utility model is, when the light of illuminating lamp tube is injected the end face of light guide plate, wherein with the parallel light rectilinear propagation in light guide plate in light guide plate surface, penetrate from the end face in addition of light guide plate, arrive reflective backplate surface, be reflected on the lamp box light penetrating panel, illuminate the character pattern on the light penetrating panel; And wherein with light guide plate surface light at an angle, then owing to " total reflection " principle in the optics, the multilayer high transmission rate material that the is configured light guide plate interface that forms that fits is repeatedly reflected, finally also go out from other end-fire, reflex on the lamp box light penetrating panel through reflective backplate surface, illuminate the character pattern on the light penetrating panel.
The utility model has the advantages that fluorescent tube quantity is few, but casing thickness attenuate, the brightness of lamp box light penetrating panel improves, and illumination is even.Because the light that the Illuminative for sign fluorescent tube sends all is reflected on the light penetrating panel of lamp box, so the required illuminating lamp tube quantity of this lamp box is few, energy consumption lowers.Because light guide plate is for equidistantly stepped, the brightness that the back produces on the lamp box light penetrating panel so light is reflected is uniform.Compare with existing general advertisement lamp box, have ultra-thin, energy-conservation, even brightness characteristics.Be applicable to general indoor and outdoor commercial advertisement displaying, also can be applicable to public place luminous characters, figure Warning Mark, multiple occasion and purposes such as various indoor illumination light fittings, photo luminous photo frame, medical viewing equipment.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of thin, planar lamp box
As seen from the figure, thin, planar lamp box of the present utility model, by casing, illuminating lamp tube, reflective base plate, light penetrating panel is formed, two conventional fluorescent lamps that be arranged in parallel in casing 1 both sides are made illuminating lamp tube 2, adopt the aluminium foil of high reflectance to make reflective base plate 3, between illuminating lamp tube, reflective base plate the place ahead, oblique be provided with two by 8-10 floor height transmittance organic glass fit form, be the equidistant stair-stepping light guide plate 4 of tread, be painted with copy, pattern on the lamp box light penetrating panel glass 5.
