Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of LED light based on microlens array group, comprising: pedestal 1,
LED mounting plate 2, the LED light 3 on the LED mounting plate 2, microlens array group 4 corresponding with the LED light 3, with
The cover board 5 that the lid of pedestal 1 closes.If the microlens array group 4 include: several in array arrangement first lenticules 41,
Dry in the second lenticule 42 of array arrangement and the leaded light of fixed first lenticule 41 and second lenticule 42
Substrate 43.The quantity of first lenticule 41 and second lenticule 42 is equal with the quantity of the LED light 3.Institute
It is identical as the material of second lenticule 42 to state the first lenticule 41, is optics acrylic or optical polycarbonates.It is described
The material of light guide base plate 43 is optics acrylic or optical polycarbonates.The light transmittance of optics acrylic or optical polycarbonates is non-
Chang Gao, excellent in weather can be effectively reduced light loss.The light guide base plate 43 and first lenticule 41 and described second
Be adhesively fixed between lenticule 2 by optics OCA glue (being not drawn into figure), the OCA glue with a thickness of 10 μm -75 μm.
Optics OCA adhesive have high clarity, high light transmittance (full light transmittance > 99%), high adhesion, high-weatherability, thickness by
Control, for a long time using yellow (xanthochromia), removing and rotten will not be led to the problem of.A hollow-out parts are equipped in the middle part of the cover board 5
51, the size of the hollow-out parts 51 is greater than the size of array composed by second lenticule 42, second lenticule 42
The composed embeddable hollow-out parts 51 of array.It is equipped with a mounting base 11 at the top of the pedestal 1, is easily installed.This is practical new
Type plays good homogenization to light using microlens array group, and the light for issuing LED light is more uniform, without hot spot.
Referring to Fig. 3, first lenticule 41 includes the first incidence surface 411 and the first light-emitting surface 412, described second
Lenticule 42 includes the second incidence surface 421 and the second light-emitting surface 422.First incidence surface 411 is concave surface, and described second goes out
Smooth surface 422 is concave surface, and first incidence surface 411 and second light-emitting surface 422 are free form surface.First lenticule
41 with second lenticule 42 be axially symmetric structure, second light-emitting surface 422 be first incidence surface 411 led along described
Photopolymer substrate 43 symmetrically overturning institute at.Specifically, X-axis, Y-axis and Z of the free form surface described in the utility model in three-dimensional system of coordinate
Relationship in axis direction is as follows: using one jiao of curved surface as origin, Z=(X2+Y2The value range of)/a, a are 300-500mm, in formula
Z is the height of Z-direction, and X is the length of X-direction, and Y is the length of Y direction, and the unit of X and Y are millimeter.Described
One light-emitting surface 412 is rectangle plane with second incidence surface 421, and the light guide base plate 43 is set to first light-emitting surface 412
Between second incidence surface 421.In use, the LED light emits beam, it is bent that optics reaches first incidence surface 411
Face is projected by the plane of first light-emitting surface 412 hence into the light guide base plate 43 through superrefraction, then takes in described the
The plane of two incidence surfaces 421 is reached the curved surface of second light-emitting surface 422 by the plane of second incidence surface 421 again, is passed through
The refraction of second light-emitting surface 422 eventually arrives at shadow surface.Here ignore the light guide base plate 43 and the optics OCA glue
A little influence on light.Light can be exhaled uniformly after the refraction of concavees lens, keep ambient light more uniform,
Have not a particle of the hot spot of a bit.
Referring to Fig. 1, the LED light based on microlens array group can be designed to arbitrary shape, specifically, this
The shape of LED light based on microlens array group described in embodiment is rectangle.The microlens array group 4 of rectangle is easier to
Molding.
In conclusion the utility model plays good homogenization to light using microlens array group, send out LED light
Light out is more uniform, without hot spot；Two groups of microlens arrays, which cooperate, forms one group of concave lens, and light is made to go out light second
Face deviation, so as to well be homogenized divergence of beam；Light irradiated area after diverging homogenizing is big, can be bigger space
Effective lighting is provided.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
