Description
Technical field
The utility model is related to the dispersive propagation fields of geometric optics, more particularly, to the technical field of diffuser plate.
Background technology
Diffuser plate is acrylic/PC plate material using optical grade, and then using has high reflectivity and the not high-tech of extinction
Skill material is the high-tech product that linear light source is changed into area source.
Now diffuser plate in the art is used among various displays, such as LED flat lamp, FPD and television set
Backlight module, light diffusing sheet instigator with PMMA, PC, PET, PS, PP is base material, adds a certain proportion of light in the substrate and expands
Powder increases the scattering and transmission of light, and while covering light emitting source and dazzling light source, and it is more soft that entire resin can be made to send out
With beautiful, graceful light reaches the opaque comfortable effect of light transmission.
Present technology has following two shortcoming and deficiency：
When since PS, PP base material are cost-effective, but physical property has critical defect, and weatherability is poor, non-refractory, easily yellow
The shortcomings of change, leads to the diffuser plate produced with this two base material, extremely short using mission.
Second is that if only adding the diffuser plate of pure light diffusing agent, in the flat lamp applied to LED directly-down light sources,
When shorten lamp bead and diffuser plate apart from when, the phenomenon that will produce leakage lamp bead, even if light diffusing agent addition is more again, be also unable to reach
The covering to light pearl in certain distance.Due to the requirement of this distance, need to be maintained at a distance from diffuser plate using light source
8CM or more, the lamps and lanterns produced in this way, thickness is excessive, and cost is naturally excessively high, and especially carrying cost is high.
