Description
Technical field
The utility model belongs to technical field of lamps, refers in particular to a kind of compound TIR combinations dentation reflection shot-light lens.
Background technology
By feat of many advantages, overall application rises LED light source in lighting area, the wherein secondary light-distribution of optical lens
To key effect.The shot-light lens of low-angle cause lens cost to remain high mostly by the way of lens power-up plating at present.
The light that LED luminescence chips are sent be transmitted through after secondary lens being carried out according to the curvature on secondary lens surface refraction and
Total reflection, due to different colours（Frequency）Optical index difference, the uniformity of hot spot, and LED luminescence chips can be influenced
The light sent is incided by individual layer secondary lens to be easier to form " macula lutea " phenomenon on diffuser plate.
Utility model content
The purpose of this utility model is to provide it is a kind of reduce cost, hot spot uniformly and eliminate macula lutea compound TIR combination
Dentation reflects shot-light lens.
To reach above-mentioned purpose, the solution of the utility model is：
A kind of compound TIR combinations dentation reflection shot-light lens, including outer Reflective seat, reflective boss and interior Reflective seat；It is described
Interior Reflective seat is located at the center of outer Reflective seat, and the reflective boss is arranged on the center of interior Reflective seat, the outer Reflective seat it is reflective
Face is consistent with the reflective surface direction of interior Reflective seat；The multiple sawtooth of reflective surface consecutive intervals projection of the outer Reflective seat, it is described interior
Reflective seat includes more than the two layers TIR structure with scale and shell shape reflecting surface, and the top surface of the reflective boss is compound eye structural, described
The side of reflective boss is in scale and shell face.
The top surface of the reflective boss is cambered surface.
The outer Reflective seat is in horn-like.
The reflective surface of the interior Reflective seat is inverted cone surface.
After adopting the above technical scheme, the utility model is multiple by the reflective surface consecutive intervals projection of the outer Reflective seat
The design of sawtooth, using dentation total reflection principle, can play the effect with electroplating in the prior art, adjust the angle of sawtooth with
The i.e. controllable light emitting angle of radian, so as to fulfill exempting to electroplate, reduces cost, and coordinate the interior Reflective seat to include more than two layers and have
There is the design of the TIR structures of scale and shell shape reflective surface, using calculus scale and shell technology, it can be achieved that the multiple of the path of light adjusts,
Avoid the generation of aberration phenomenon and macula lutea phenomenon, and be compound eye structural with reference to the top surface of the reflective boss, the reflective boss
Side be in scale and shell face design, using compound eye mixed light technology and miniature scale and shell mixed light technology, so that the side of the reflective boss
Face can make that the hot spot of the light by sawtooth reflection is uniform, and the top surface of the reflective boss with compound eye structural can be eliminated or subtracted
Influence of the weak aberration to hot spot, obtains light mixing effect evenly, therefore the utility model can be eliminated effectively in hot spot
Macula lutea effect, obtains uniform hot spot.

Embodiment
To reach above-mentioned purpose and effect, technological means and construction used by the utility model, hereby draw with regard to this practicality
New its feature of preferred embodiment elaborate and function are as follows, are understood completely with sharp.
TIR (Total Internal Reflection) lens refer to the lens system designed using inner full-reflection principle
System, because the characteristic of its high-effective concentration is used widely.
Shown in please referring to Fig.1 to Fig.3, the utility model discloses a kind of compound TIR combinations dentation reflection shot-light lens, bag
Include outer Reflective seat 1, reflective boss 2 and interior Reflective seat 3.
The interior Reflective seat 3 is located at the center of outer Reflective seat 1, and the reflective boss 2 is arranged on the center of interior Reflective seat 3, institute
The reflective surface of outer Reflective seat 1 is stated with the reflective surface of interior Reflective seat 3 towards unanimously；The reflective surface consecutive intervals of the outer Reflective seat 1
The multiple sawtooth 11 of projection, using dentation total reflection principle, can play the effect of plating, adjust the angle and radian of sawtooth 11, i.e.,
Controllable light emitting angle, reduces cost, and the interior Reflective seat 3 includes three layers of TIR structures 31 with scale and shell shape reflecting surface, its
In, the contained TIR structures 31 with scale and shell shape reflecting surface of the interior Reflective seat 3 are more than two layers, utilize calculus scale and shell
Technology avoids the generation of aberration phenomenon and macula lutea phenomenon, makes hot spot uniform, it can be achieved that the multiple adjustment in the path of light, described
The top surface 21 of reflective boss is compound eye structural and is cambered surface, using compound eye mixed light technology, have the described reflective convex of compound eye structural
The top surface of platform can eliminate or weaken influence of the aberration to hot spot, obtain light mixing effect evenly, the side of the reflective boss
22 be in scale and shell face, and using miniature scale and shell mixed light technology, the side 22 of the reflective boss can make the light by sawtooth reflection
Hot spot is uniform, and the outer Reflective seat 1 is in horn-like, and the reflective surface of the interior Reflective seat 3 is inverted cone surface.
Therefore, the utility model be installed on the luminous end of light source and the upper end cover of the utility model set one allow it is vertical
During the lenticular body of outgoing, the light of wide-angle reflects via reflective boss 2 or after TIR structures 31 reflects, and is all-trans via lenticular body
Penetrate, then be totally reflected by sawtooth 11 so that light can be emitted perpendicular to lenticular body, and be formed after being totally reflected via sawtooth small
Angle light, is emitted, light via the total reflection of sawtooth 11 and vertical lens body again after being adjusted via the scale and shell face of reflective boss 2
Vertical lens body is emitted after the low-angle light that source is sent can be adjusted via reflective boss 2, so the utility model can have
Effect ground eliminates the macula lutea effect in hot spot, obtains uniform hot spot, also makes lens-shape beautiful, cost reduction, with more market
Competitiveness.
The technology contents and technical characterstic of the utility model have revealed that as above the quantity of the building block of the utility model is simultaneously
It is not limited with above-mentioned, those skilled in the art is still potentially based on the announcement of the utility model and makees various new without departing substantially from this practicality
