The diffused light layer is arranged on the right side of the light guide layer and the reflected light layer is arranged on wrong side of the light guide layer. The light source is arranged on the side of the light guide layer, which is in cascade shape of the right side. The wrong side of the diffused light layer is in cascade shape, matching with the right side of the light guide layer. The reverse side of the light guide layer is provided with reflected light point, which is the resin mixing with titanium dioxide or barium titanate. The material of diffused light layer is the acrylic mixing with titanium dioxide or barium titanate medium, and also could be the polycarbonate mixing with titanium dioxide or barium titanate medium. The material of diffused light layer could also be polyester astigmatic film. The material of light guide layer is acrylic or polycarbonate. The material of reflected light layer is polyester reflecting film or metallic film or metallic-membrane planting. The power supply is the LBD or cold-cathode tube. The utility model has the advantages of high brightness, even illumination, good illumination effect and large area.
Description
Technical field
The utility model relates to board-like backlight, particularly a kind of plate for high luminance light guide.
Background technology
The backlight of existing mobile phone, LCD, sign adopts light guide plate usually, light guide plate is made up of diffusion layer, optical waveguide layer, reflector layer, light source, the shortcoming of existing light guide plate is that optical waveguide layer is an one flat plate, pro and con is all very smooth smooth, when light source shines from the side, light passes through optical waveguide layer, wherein sub-fraction light generation scattering, make the positive luminous of light guide plate, but most of light is because positive parallel with optical waveguide layer, directly by light guide plate, from the opposite side ejaculation of light guide plate, not only make the brightness in light guide plate front not too high, and light efficiency is bad.Adopt above-mentioned this structure, it is very big that the area of light guide plate can not be done, otherwise, influence its luminosity and uniformity coefficient.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of plate for high luminance light guide is provided, and its brightness height, luminous evenly lighting effect is good, and area can do very big.
The purpose of this utility model is achieved in that a kind of plate for high luminance light guide, form by diffusion layer, optical waveguide layer, reflector layer, light source, diffusion layer is arranged in the front of optical waveguide layer, reflector layer is arranged in the reverse side of optical waveguide layer, light source arrangement is in the side of optical waveguide layer, and the front of described optical waveguide layer is stepped.
The back side of described diffusion layer is stepped, coincide with the positive corresponding of described stepped optical waveguide layer.
There is reflective spot at the back side of described optical waveguide layer, and this reflective spot is the resin that is mixed with titania or barium titanate.
The material of described diffusion layer is the acrylic that is mixed with titania or barium titanate medium.
The material of described diffusion layer is the polycarbonate that is mixed with titania or barium titanate medium.
The material of described diffusion layer is the polyester light-diffusing film.
The material of described optical waveguide layer is acrylic or polycarbonate.
The material of described reflector layer is the polyester reflective membrane.
The material of described reflector layer is metal film or metal coating.
Described light source is light emitting diode or cold-cathode tube.
The utility model has following positive beneficial effect: the stepped front of optical waveguide layer, the light of direct projection is from the side reflected, wherein a part is refracted on the reflector layer at the optical waveguide layer back side, penetrate from the front of optical waveguide layer through the reflector layer reflection, another part is refracted on the diffusion layer in optical waveguide layer front, penetrate from the front of diffusion layer, improved luminosity and uniformity coefficient.Reflective spot also plays all effects of light, can make the even scattering of light, makes lighting effect good.Light reflects step by step by the front of stair-stepping optical waveguide layer, can arrive very big scope with the extension of ladder, and also there is enough illumination brightness in place far apart from light source on the optical waveguide layer, so that the area of light guide plate of the present utility model can be done is very big.
