Abstract
The utility model discloses a lamp-used PC light diffusion plate comprising a PC transparent layer, a light diffusion layer, an anti-UV layer and a surface treatment layer. The lamp-used PC light diffusion plate is characterized in that the light diffusion layer and the anti-UV layer are respectively arranged at the two sides of the light diffusion layer in a co-extrusion mode; the anti-UV layer is arranged on the outer side of the light diffusion layer in a co-extrusion mode; the surface treatment layer is arranged on the outer side of the anti-UV layer connected with the light diffusion layer. The lamp-used PC light diffusion plate of the utility model is beautiful in appearance, long in usage life, good in light diffusion effect and uniform in luminescence. The lamp-used PC light diffusion plate is a high performance light diffusion plate which can satisfy lamp usage demands.
Description
Technical field
The utility model relates to a kind of PC plate, especially a kind of light fixture PC light diffusing sheet.
Background technology
Along with the Rapid Popularization of LED light fixture, the making problem of lampshade is all perplexing light fixture production firm always, should have high transmittance to do prerequisite, takes into account again suitable light diffusivity and good light source disguise simultaneously.Original adoption glass is produced lampshade, but Glass breadks easily, and light diffusion effect is not good.Developed into resin and replace glass afterwards, if only make lampshade with transparent resin, although transmittance is very high, but scattering of light effect is not ideal enough, and the hidden poor performance of light source has had a strong impact on the illumination of LED lamp.When lampshade uses the milky white PC plate of regular grade, its transmittance only has 20%, although the milky white PC plate of regular grade can be by light penetration simultaneously, but be difficult to even astigmatism, and PC light diffusing sheet transmittance can reach more than 80%, and the light that fully scattering LED light source sends, therefore can be widely used in fields such as advertising lamp boxs.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of good looking appearance, long service life, good, the luminous uniform light fixture PC light diffusing sheet of light diffusion effect.
The technical solution of the utility model is: a kind of light fixture PC light diffusing sheet, comprise PC hyaline layer, light diffusion layer, anti-UV layer and surface-treated layer, it is characterized in that: there are light diffusion layer and anti-UV layer in described PC hyaline layer both sides respectively co-extrusion, outside light diffusion layer, co-extrusion has anti-UV layer, and the anti-UV layer outside being connected with light diffusion layer is provided with surface-treated layer.
Described surface-treated layer is frosted layer or stratum granulosum.
The beneficial effects of the utility model are:
1. surface-treated layer can promote the effect of light diffusion by the diffuse reflection of surperficial light, and it,, according to the requirement of design, can suppress the figures such as frosted, rhombohedra particle in the above, makes PC plate profile more attractive in appearance.
2. anti-UV layer can prevent that PC resin from producing aging Yellowing under ultraviolet ray is irradiated, and improved serviceable life, and ensured translucent effect.
3. light diffusion layer is to add light diffusing agent in PC resin, spherical smooth diffusion particle is dispersed in PC resin, form island structure, because the refraction index of PC resin and light diffusing agent is different, the reflection that light produces similar minute surface on light diffusing agent surface, just can obtain good light diffusion effect after multiple reflections, refraction.
Accompanying drawing explanation
Fig. 1 is the structural representation of PC light diffusing sheet for light fixture described in the utility model.
In figure, 1-surface-treated layer, the anti-UV layer of 2-, 3-light diffusion layer, 4-PC hyaline layer.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, a kind of light fixture PC light diffusing sheet, comprise PC hyaline layer 4, light diffusion layer 3, anti-UV layer 2 and surface-treated layer 1, in PC hyaline layer 4 both sides, co-extrusion has light diffusion layer 3 and anti-UV layer 2 respectively, light diffusion layer 3 outside co-extrusions have anti-UV layer 2, anti-UV layer 2 outside that are connected with light diffusion layer 3 are provided with surface-treated layer 1, and in the present embodiment, surface-treated layer 1 is rhombohedra particle layer.
The utility model guarantees under the prerequisite of high transmission rate, light diffusivity and the mist degree of product have been increased again, by the effect of light diffusion layer 3, make whole plate face form a uniform light-emitting area and do not form dark space, avoid on picture, forming afterimage, thereby reach the glittering and translucent visual effect of entire body.The utility model good looking appearance, long service life, light diffusion effect is good, luminous even, is a kind of high-performance optical diffuser plate that can meet light fixture user demand.
That in above-described embodiment and instructions, describes just illustrates principle of the present utility model and most preferred embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
Claims (2)
1. a light fixture PC light diffusing sheet, comprise PC hyaline layer, light diffusion layer, anti-UV layer and surface-treated layer, it is characterized in that: there are light diffusion layer and anti-UV layer in described PC hyaline layer both sides respectively co-extrusion, outside light diffusion layer, co-extrusion has anti-UV layer, and the anti-UV layer outside being connected with light diffusion layer is provided with surface-treated layer.
2. light fixture according to claim 1 PC light diffusing sheet, is characterized in that: described surface-treated layer is frosted layer or stratum granulosum.
