Description
Technical field
The invention belongs to LED lens technical fields, concretely relate to one kind and square focus spot Uniform Illumination may be implemented
Non-spherical lens.
Background technology
The light efficiency of large power white light LED has reached 100lm/w at present, and the light efficiency of stable product also has 90lm/w or more,
This light efficiency so that LED enters general lighting, has especially belonged to the field of directional lighting in road lighting etc.
It is gradually applied, still, since the price of current LED is more much higher than conventional light source, popularizations of the LED for general lighting is necessary
Premised on the whole light efficiency for improving LED illumination System, and this will rely on the effective light utilization efficiency for improving LED light.
For current LED street lamp, LED tunnel lamp, when LED operation, generated light beam penetrated directionality before being, also
It is little that there are illumination ranges, intensity of illumination defect unevenly distributed on road surface, to limit the roads LED to a certain extent
The popularization and application of lamp, LED tunnel lamp improve the uniformity of light shield to effectively control LED beam, improve luminous flux, this will
With it secondary light-distribution is carried out with secondary optics.Light cup, optical reflective disk etc knot are mostly used in terms of existing LED secondary light-distributions greatly
Structure improves the LED illumination uniformity with this, however existing such technical solution makes light beam cross over many times reflection or refraction, and light is logical
Amount is influenced the illumination performance of LED by considerable degree of decaying.
In addition, also LED light is handled using optical lens at present, but existing optical lens design is back
Body is revolved, generated hot spot is circular light spot, cannot meet the rectangle of single pixel point or the needs of square focus spot, and illumination
Effect is undesirable.
Invention content
The object of the present invention is to provide a kind of non-spherical lenses that square focus spot Uniform Illumination may be implemented, and are intended to solve
Problems of the prior art.
In order to solve the above technical problems, the object of the present invention is achieved like this：
A kind of non-spherical lens that square focus spot Uniform Illumination may be implemented, is used in the front of LED chip, and feature exists
In：Including：Lens body, the lens body bottom surface are more than top, are incidence surface to the lens body bottom surface, and top is
Light-emitting surface, the lens body bottom surface are more than top, are incidence surface to the lens body bottom surface, and top is light-emitting surface, institute
It is that bottom surface extends to both tops surface blending to state lens body, the perpendicular any cross of the center line of the lens body
Cross sectional shape is the arc side and four straightways for respectively connecting adjacent two arc sides endpoint of four point symmetries, the lens
The recess of body floor indented central dome shape, the recess peak are located on lens body center line, and formation makes from LED core
The incidence surface of the light incidence of piece output.
Preferred embodiment on the basis of said program and as said program：The lens body material is moulded for optics
Material, optical plastic good in optical property are easy to large batch of, the industrialized manufacturing, and production cost is low.
Preferred embodiment on the basis of said program and as said program：The lens body plays to form square light
Spot acts on.
Preferred embodiment on the basis of said program and as said program：The LED chip includes visible light, infrared
Light, ultraviolet light, while including monochromatic light, complex light, single led use, and this can be not only corresponded to single lens thoroughly in this way
Lens can be corresponded to multiple LED with single lens and be used, to realize other colour switchings such as RGB.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：Aspherical light of the LED light by the present invention
Lens are learned, hot spot is made to become rectangle from circle, and keep the illumination at middle part stronger；In addition, the illumination patterns of hot spot are also no longer
Mixed and disorderly, become rational linear distribution.

Specific implementation mode
To keep the purpose, technical scheme and advantage of the application clearer, below in conjunction with the attached drawing 1-7 in embodiment,
Technical solution in embodiment is clearly and completely described,
A kind of non-spherical lens that square focus spot Uniform Illumination may be implemented is used in the front of LED chip 10, including：Thoroughly
Mirror main body 20, the perpendicular any cross-sectional shape of the center line of the lens body 20 are the first arc side of four point symmetries
241, the second arc side 242, third arc side 243, the 4th arc side 244 and four articles are respectively by the first of the connection of adjacent two arc sides endpoint
Straightway 251, second straight line section 252, third straightway 253, the 4th straightway 254,20 bottom surface 23 of the lens body are more than
Top 22, is incidence surface to the lens body bottom surface 23, and top is light-emitting surface, 20 bottom surface indented central spherical surface of lens body
The recess 21 of shape, 21 peaks of the recess are located on lens body center line 24, and formation makes the light exported from LED chip 10 enter
The incidence surface penetrated.
20 material of the lens body is optical plastic.
The lens body 20 plays the role of forming square focus spot.
