Description

A kind of optical waveguide layer light-emitting 3 D font

Technical field

The utility model relates to the light-emitting 3 D font that occasions such as a kind of advertisement, signboard, decoration are used, and particularly a kind of employing LED lamp (light emitting diode) is as light source and by the whole luminous light-emitting 3 D font of optical waveguide layer.Be suitable as outdoor relatively large font.

Background technology

The present light-emitting 3 D font used as occasions such as the advertisement of light source, signboard, decorations of the employing LED lamp that generally uses, just like Chinese patent 200320120531.1 disclosed a kind of stereo luminous characters, its structure is that the matrix of stereo luminous character is composited by the multi-layer transparent resin material, be followed successively by transparent surface layer, color layers, scattering layer, luminescent layer from top to bottom, in luminescent layer, be embedded with a plurality of light emitting diodes equably, substrate layer be set at the luminescent layer bottom.The defective of this class light-emitting 3 D font is: the one, and light emitting diode master direction of illumination and scattering layer, color layers and transparent surface layer are perpendicular, because light emitting diode is the high luminous form of point of brightness, so the illumination brightness on the luminous stroke of seeing from transparent surface layer outside is significantly inhomogeneous, has influence on the attractive in appearance of luminescent characters; The 2nd, in order to reduce the unevenness of the illumination on the luminous stroke, scattering layer must be enough thick, causes font thickness bigger, needs usage space big and cost is higher; The 3rd, the font architecture layer is too much, causes complex structure, makes trouble, cost is higher.

Summary of the invention

In order to overcome existing similar light-emitting 3 D font illumination brightness irregularities, font thickness is bigger, needs usage space big, complex structure, making trouble, the higher defective of cost, the utility model provides a kind of improved optical waveguide layer light-emitting 3 D font, can overcome the defective of prior art.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of optical waveguide layer light-emitting 3 D font, it is characterized in that: the stroke cross section structure of font is by color layers, optical waveguide layer and reflector layer constitute, wherein color layers is in the optical waveguide layer end face, reflector layer is in the optical waveguide layer bottom surface, edge on the optical waveguide layer bottom surface is provided with the lamp with groove, the soft lamp band of LED is installed in the lamp with groove, the main direction of illumination of the LED lamp on the soft lamp band of LED and optical waveguide layer bottom surface almost parallel and towards the optical waveguide layer inboard, be distributed with the indent striped of refracted ray on the optical waveguide layer bottom surface, the reflective surface of reflector layer is fitted on the optical waveguide layer bottom surface.

The so-called font of technique scheme is meant Chinese text, other countries' literal, phonetic, punctuation mark or indicia patterns etc.

The font color layer of technique scheme can be by coloured printing opacity or coloured light tight sheet material or the shaping of sheet material cutting processing, the font optical waveguide layer can be shaped by water white transparency sheet material or colored transparent sheet material cutting processing, the font reflector layer can belong to sheet material or the sheet material cutting processing shaping of color table layer as reflective surface by white top layer or bright gold, and color layers, optical waveguide layer and reflector layer applying are fixed together and become font architecture then.The base material of font reflector layer can be plastics, paper, metal material.

The described lamp with groove of technique scheme can be the optical waveguide layer edge contour curve extension distribution along the font stroke.The lamp with groove can also be the optical waveguide layer edge contour curve around all strokes of font.

The indent striped that the described indent striped of technique scheme can be a net distribution.

The soft lamp band of the described LED of technique scheme can buy at present on the market, and structure is a flat thin arbitrarily soft band of bending, is intervally distributed with LED lamp one by one on it, and the power supply that the LED lamp is extended in the end of soft band connects lead.

The beneficial effects of the utility model are: because the stroke cross section structure of font is by color layers, optical waveguide layer and reflector layer constitute, wherein color layers is in the optical waveguide layer end face, reflector layer is in the optical waveguide layer bottom surface, edge on the optical waveguide layer bottom surface is provided with the lamp with groove, the soft lamp band of LED is installed in the lamp with groove, the main direction of illumination of the LED lamp on the soft lamp band of LED and optical waveguide layer bottom surface almost parallel and towards the optical waveguide layer inboard, so the LED lamp on the soft lamp band of LED at first is to survey to illuminate whole leaded light body layer by layer in the lamp with groove, illuminate color layers by whole shinny optical waveguide layer then, like this from the color layers outside, the luminosity of font is quite even, can give full play of the luminous aesthetic feeling of font; Because this illumination mode optical waveguide layer need not be thick, so the thickness of font attenuate greatly, usage space can reduce and cost can reduce; Owing to be distributed with the indent striped of refracted ray on the optical waveguide layer bottom surface, the reflective surface of reflector layer is fitted on the optical waveguide layer bottom surface, so light that penetrates from the optical waveguide layer bottom surface, can reflect to the reflective surface of indent striped on the optical waveguide layer bottom surface and reflector layer to the optical waveguide layer end face, light is focused on the color layers, improved the luminosity of font; Because the refraction mode of this light can make the side of font stroke reflect light, not only can improve the stereoscopic sensation of luminous font, and can set off out lighttight font color layer by luminous character contour, become novel light-emitting 3 D font; Because the stroke cross section structure of font only is made of color layers, optical waveguide layer and reflector layer, wherein color layers is in the optical waveguide layer end face, reflector layer is in the optical waveguide layer bottom surface, edge on the optical waveguide layer bottom surface is provided with the lamp with groove, the soft lamp band of LED is installed in the lamp with groove, so relatively simple for structure, easy to make, cost is lower.

The utility model will be further described below in conjunction with drawings and Examples.
