Description
Technical field
The utility model relates to the technical field of PS diffuser plate, especially a kind of LED flat lamp PS diffuser plate.
Background technology
In the process that LED illumination lamp is accepted by market gradually, problem about LED lamp face shield perplexs light fixture production firm always, high transmittance should be had to do prerequisite, accomplish again there is suitable light diffusivity and good light source is disguised simultaneously, improve the effect of light fixture and light source dazzling for LED is become soft, healthy light source is the direction that current research staff is studying.Original adoption glass makees lampshade, but Glass breadks easily, and the diffusion effect of light neither be fine, is difficult to reach lighting requirement.Developed into gradually afterwards and replace glass with resin, and if only make lampshade with transparent resin, although transmittance is high, substantially can reach more than 90%, but the diffusion effect of light was undesirable, light source is disguised poor.White resin, it is too low to there is transmittance in it, has had a strong impact on the illumination of LED.Just adopt in this way and add milky pigment, the technological means such as surface frosted is auxiliary, although solve light source shielding sex chromosome mosaicism like this, but it is too low to there is transmittance, had a strong impact on the light efficiency of LED illumination, the problem therefore spreading face shield perplexs in the problem of transmittance and the such contradiction of light source shielding always.
PS diffuser plate is a kind of material with light diffusing character in PS (polystyrene) sheet material kind, acrylic (PMMA), PC, PP, one in the material diffuser plate classifications such as PS, there is certain mist degree, transmittance, the optical signature of the plastic plates such as refractive index, can effectively point or line source be converted into soft, uniform area source, under the prerequisite reaching good transmittance, there is good light source dot matrix shielding simultaneously, add that price is relatively economical, thus be widely used on flourish LCD-TV and LED illumination product, a kind of selection of optical diffusion material is added for LED illumination product secondary light-distribution.The proportion of PS diffuser plate only has 1.047 ~ 1.049, when all-transparent, transmittance is 87%, it is the second high transparency material that in plastics, refractive index is only second to PC, mass ratio PC, PMMA etc. are light, greatly reduce transportation cost, weatherability very easily turns yellow, and very easily embrittlement when extremely cold, cost ratio PC, PMMA etc. are cheap and adopted on a large scale.
Although, in the market LED illumination lamp greatly uses PS diffuser plate, but these PS diffuser plates mainly add chemical particle as scattering particle in PS base material, make light constantly reflect in the medium that two refractive indexes are different through scattering layer, reflect and scattering, produce the effect of optics diffusion with this.But this mode, by inevitably there is the absorption of diffusion particle to light, cause the efficiency of light energy utilization low.The chemical particle of frequent interpolation comprises: organic light diffusing agent and inorganic light diffusing agent.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, a kind of LED flat lamp PS diffuser plate is provided, ensureing, under higher transmittance, light diffusivity and the concealed prerequisite of good light source, can also the efficiency of light energy utilization be improved.
The utility model solves the technical scheme that its technical matters adopts: a kind of LED flat lamp PS diffuser plate, there is the diffusion flaggy of mutual lamination setting and guide-lighting flaggy, the upper surface of described diffusion flaggy is disposed with V-type groove array thin plate layer, U-shaped tongue array thin plate layer and circular display thin plate layer from the bottom up, and the lower surface of described guide-lighting flaggy is disposed with pyramid array thin plate layer, square display thin plate layer and microlens array thin plate layer from top to bottom.
Further, the thickness ratio spreading flaggy and guide-lighting flaggy described in technique scheme is 5:4.
Further, the thickness of the groove array of V-type described in technique scheme thin plate layer, U-shaped tongue array thin plate layer, circular display thin plate layer pyramid array thin plate layer, square display thin plate layer and microlens array thin plate layer is equal.
Further, the cross sectional shape spreading flaggy, guide-lighting flaggy, V-type groove array thin plate layer, U-shaped tongue array thin plate layer, circular display thin plate layer pyramid array thin plate layer, square display thin plate layer and microlens array thin plate layer described in technique scheme is equal, and perimeter of section is also equal.
The beneficial effects of the utility model are: a kind of LED flat lamp PS diffuser plate of the present utility model, by changing the shape of microstructure and different arrangement, diffusion angle, the space of light field and energy distribution can be adjusted, realize the uniformity coefficient of light diffusing sheet and the impact of transmittance, ensureing, under higher transmittance, light diffusivity and the concealed prerequisite of good light source, can also the efficiency of light energy utilization be improved.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, spread flaggy, 2, guide-lighting flaggy, 3, V-type groove array thin plate layer, 4, U-shaped tongue array thin plate layer, 5, circular display thin plate layer, 6, pyramid array thin plate layer, 7, square display thin plate layer, 8, microlens array thin plate layer.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of LED flat lamp PS diffuser plate of the utility model as shown in Figure 1, there is diffusion flaggy 1 and the guide-lighting flaggy 2 of the setting of mutual lamination, the upper surface of described diffusion flaggy 1 is disposed with V-type groove array thin plate layer 3, U-shaped tongue array thin plate layer 4 and circular display thin plate layer 5 from the bottom up, and the lower surface of described guide-lighting flaggy 2 is disposed with pyramid array thin plate layer 6, square display thin plate layer 7 and microlens array thin plate layer 8 from top to bottom.
Wherein, described diffusion flaggy 1 is 5:4 with the thickness ratio of guide-lighting flaggy 2.The thickness that described V-type groove array thin plate layer 3, U-shaped tongue array thin plate layer 4, circle display thin plate layer 5 pyramid array thin plate layer 6, square display thin plate layer 7 and microlens array thin plate layer 8 is equal, and thickness is 0.2 ~ 0.5mm.The cross sectional shape of described diffusion flaggy 1, guide-lighting flaggy 2, V-type groove array thin plate layer 3, U-shaped tongue array thin plate layer 4, circular display thin plate layer 5 pyramid array thin plate layer 6, square display thin plate layer 7 and microlens array thin plate layer 8 is equal, and perimeter of section is also equal.The light therethrough diffusion layer of diffusion flaggy 1, can pass in the medium different with refractive index, makes light that the phenomenon of many refractions, reflection and scattering occur, and can revise the light uniformly effect that spreads to reach optics of area source.
