Description
Technical field
The invention is related to diffuser plate technical field, more particularly to a kind of Anti-glare LED lamp.
Background technology
When the brightness of light source is high or when background and the larger luminance difference of central region, will produce " dazzle ".It is " dizzy
Light " not only influences viewing, and all has an impact to vision health.In in flat LED light fixture, it usually needs increase for spreading
Plate, the main function of diffuser plate are that light scatter, so as to prevent dazzle.
At present, the diffusion mode of light diffusing sheet has two kinds, and one kind is that light diffusing agent is added in light-passing board, light through
Some light can change direction by light diffusing agent during light-passing board, so that light sheds to surrounding.Another form
It is then to increase some micro-structurals on the surface of light-passing board, making the surface of light-passing board becomes uneven, therefore light is in light-passing board
Surface outgoing when, exit direction can be also changed.In order to obtain more diffusion effect, both comprehensive features are proposed in the industry
Diffusion panel products, i.e., diffusant is both added in a piece of light-passing board, also the piece light-passing board exit facet set micro-structural, from

Invention thinking：The main reason for finding, failing to produce a desired effect, is after the applicant's analysis：Diffusant is to light
Diffusion process be that the light that light source is sent compares concentration, therefore can be by a certain zonule in diffuser plate than more random
Diffusant is diffused, under small yardstick, after the issue of diffusant is relatively less uniform, therefore light is by diffusant, and light
Can be spread, but this diffusion there may be it is uneven, and can not be by exiting surface the problem of this skewness
Micro-structural overcome because micro-structural is typically aligned transfer, uneven light is issued when reaching exiting surface by micro-
The refraction of structure, be the equal of only to change direction, the problem of light diffusion is uneven can not be made up.That is,
In whole diffusion process, can really play diffusion is only the diffusant in a zonule, most of region
Diffusant and surface micro-structure fail to play diffusion as expected, and therefore, the superposition of two kinds of structures can not obtain
Expected double effect.Therefore, the light for the concentration that improved thinking should mainly be to avoid light source from sending directly is spread
Agent is spread, but first the light of concentration is scatter with micro-structural, is allowing these scattered light quilt in each zonule
Diffusant further spreads, so as to give full play to the effect of micro-structural and diffusant.
