The utility model discloses a go into the plain noodles and be the cambered surface with reflection of light top surface, go out the plain noodles and adopt the modular design of facing directly with the cambered surface to reflection of light bottom surface is provided with anti - optical network check, make the lens body can 7mm's mixed light apart from the uniform illumination of realizing the large tracts of land under the condition, the thickness of the straight following formula LED backlight of reduction that can furthest makes the thickness of product reduce, product cost also obtains effectual control.
Description
Technical field
This utility model relates to backlight lens art, particularly relates to the uniform direct-light type LED backlight lens of a kind of irradiation.
Background technology
LED illumination is a kind of emerging lighting energy, because length in its, efficiency high in service life, it is low to consume energy and obtains wide
General application.Wherein direct LED backlight is that LED is uniformly configured in liquid crystal panel rear as luminous source, commonly used
In LCD TV.
Direct LED backlight is generally formed by LED and backlight lens combination, and backlight lens can make the light of LED
Uniform irradiation, the color making LCD TV is brighter.But backlight lens lighting angle of the prior art is little, irradiate inequality
Even, light extraction efficiency is low, it is impossible to meet the needs of people.
Summary of the invention
The technical problems to be solved in the utility model is according to above-mentioned the deficiencies in the prior art, it is provided that a kind of lighting angle
Beat, light extraction efficiency is high and irradiates uniform direct-light type LED backlight lens.
The technical solution of the utility model is as follows:
The uniform direct-light type LED backlight lens of a kind of irradiation, including lenticular body, described lenticular body upper strata is light-emitting seat, under
Layer is mounting seat；Described light-emitting seat upper surface is reflective end face, and described reflective end face is the curved circular conical surface caved in, described luminescence
Seat side is exiting surface, and described exiting surface is faced directly and gone out light cambered surface and form by going out light；Described mounting seat bottom surface is reflective bottom surface, institute
State reflective bottom surface and be provided with reflective grid；Described reflective bottom surface central authorities are provided with light source mounting hole, and described light source mounting hole is arranged
Having incidence surface, described incidence surface is made up of the light incident sides of arc and the light end face that enters of arc.
Further, described light-emitting seat is truncated cone-shaped, and described mounting seat is square.
Further, described reflective end face, exiting surface, reflective bottom surface and incidence surface are centrally located on same axis.
Further, described exiting surface is provided with spark lines.
Further, it is provided with installation suspension column bottom described mounting seat.
Compared with prior art, this utility model has the advantages that incidence surface of the present utility model and reflective roof
Face is cambered surface, and exiting surface uses and faces the modular design with cambered surface directly, and reflective bottom surface is provided with reflective grid, makes lens originally
Body can realize large-area Uniform Illumination under the conditions of the light mixing distance of 7mm, can reduce the straight-down negative LED back of the body to greatest extent
The thickness of light source, makes the thickness of product reduce (such as TV TV), and product cost is also controlled effectively.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type is described in further detail.
As Figure 1-4, the embodiment that this utility model provides, the uniform direct-light type LED backlight lens of a kind of irradiation, bag
Including lenticular body, described lenticular body upper strata is light-emitting seat 10, and lower floor is mounting seat 20；Described light-emitting seat 10 upper surface is reflective end face
11, described reflective end face 11 is the curved circular conical surface caved in, and described light-emitting seat 10 side is exiting surface, and described exiting surface is by going out light
Face 12 directly and go out light cambered surface 13 and form；Described mounting seat 20 bottom surface is reflective bottom surface 21, and described reflective bottom surface 21 is provided with reflective
Grid 22；Described reflective bottom surface 21 central authorities are provided with light source mounting hole 30, and described light source mounting hole 30 is provided with incidence surface, described
Incidence surface is made up of the light incident sides 31 of arc and the light end face 32 that enters of arc.
Described light-emitting seat 10 is truncated cone-shaped, and described mounting seat is square.
Described reflective end face 11, exiting surface, reflective bottom surface 21 and incidence surface are centrally located on same axis, make lens
The light of body injection is more uniform.
Described exiting surface is provided with spark lines, and the light making lenticular body penetrate is softer.
Being provided with installation suspension column 23 bottom described mounting seat 20, lenticular body carries out installing by installation suspension column 23 fixes.
Incidence surface of the present utility model and reflective end face 11 are cambered surface, and exiting surface employing is faced the combination with cambered surface directly and set
Count, and reflective bottom surface 21 is provided with reflective grid 22, enables lens body to realize big face under the conditions of the light mixing distance of 7mm
Long-pending Uniform Illumination, can reduce the thickness of direct LED backlight to greatest extent, makes the thickness of product reduce (such as TV electricity
Depending on), product cost is also controlled effectively.
Above disclosed only this utility model preferred embodiment, can not limit this utility model with this certainly
Interest field, the equivalent variations therefore made according to this utility model claim, still belong to the scope that this utility model is contained.
