Abstract
The invention discloses a light guide sign board suitable for fire-fighting evacuation indication or advertising boards and the like. The invention takes glass or organic glass as a substrate, a groove with a character shape or a figure is made on the substrate, and the groove is filled with light scattering materials. The light scattering material is made up by using transparent resin paint and making it undergo the processes of high-speed stirring or other processes to produce lots of dense fine bubbles or using a mixture of lots of dense glass microbeads and transparent resin paint, and making them undergo the process of quick solidification, and the end face of the base plate is equipped with light source, and the light source can be used as light-emitting diode or small bulb, etc. The sign board has bright, beautiful and striking color.
Description
The present invention relates to a kind of light guiding sign board that is applicable to the filling diffusion material of fire-fighting evacuation identification plate and billboard etc.
Existing light guiding sign board is to carve groove according to font or figure on glass or organic glass, at the identification plate end face light source is set, light conducts to groove along the glass or the organic glass medium of identification plate, groove to plain edge incident ray is formed diffuse reflection, and demonstrate font or figure.This identification plate overall contrast is low, and the font brightness irregularities, and the light source utilization factor is low.Chinese patent [95220073.2] number has proposed a kind of improvement project for this reason, promptly fills astigmatic agent in the groove of light guiding sign board, and under light source irradiation, astigmatic agent produces refraction to incident ray, and around random scatter, and bright font or the figure of clear display.But it is on sale that astigmatic agent is not seen on market, and expensive raw material price, is difficult for preparation, makes this light guiding sign board cost very high.
The purpose of this invention is to provide the simple diffusion material of a kind of preparation, be packed into light guiding sign board, can reduce the cost about 4/5ths of light guiding sign board.
The present invention is achieved in that on the glass or pmma substrate of 3～10 millimeters thick, carve the font or the figure connected in star of 1～3 millimeters deep, fill diffusion material in groove, in base board end surface light source is set, light source generally adopts miniature bulb or light emitting diode; The present invention is the improvement of this light guiding sign board, fill following astigmatic agent in the groove of font or figure: the transparency material of liquid towards carries out high-speed stirred or uses other method, generate a large amount of intensive trickle bubbles therein, after this material being inserted the groove of light guiding sign board, solidify rapidly, scatter and disappear to prevent bubble; The powder that also can the filling transparency material and the potpourri of transparent adhesive tape or lacquer, and make its curing: when light source luminescent, end face light is injected light guiding sign board, in substrate, form the photoconduction transmission, make light transfer in the groove forward, diffusion material in the groove forms random scatter to light, thereby demonstrates font or figure in the groove.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Accompanying drawing is the planimetric map of embodiment.
Among the figure: the 1st, glass or pmma substrate, the 2nd, light emitting diode, the 3rd, ornamental strip, the 4th, the diffusion material of font groove and filling.
Be to carve font groove 4 on 10 millimeters the pmma substrate 1 at thickness, be " inlet " printed words in the accompanying drawing, in groove 4, fill the transparent resin lacquer that contains a large amount of intensive bubbles, and make its rapid curing, after the substrate upper surface embeds light emitting diode 2 at a certain distance, fixing with ornamental strip 3.Pass to electric current to light emitting diode, identification plate can demonstrate bright-coloured eye-catching font.
Claims (4)
1, a kind of light guiding sign board comprises the light source on transparency carrier and the substrate end-face, it is characterized in that being carved with on the substrate groove of figure or font.
2, light guiding sign board according to claim 1 is characterized in that: be filled with diffusion material in the groove.
3, according to the diffusion material described in the claim 2, it is characterized in that: use the liquid clear material through high-speed stirred, and generate a large amount of intensive trickle bubbles therein, and can solidify rapidly.
4, according to the diffusion material described in the claim 2, it is characterized in that: the powder of transparency material, mix with the clear lacquer or glue, and can solidify.
