Description
Technical field
The present invention relates to optical lenses technical field, and in particular to a kind of lens arrangement of dentation.
Background technology
In converging optical design, the technology of maximum application is based on reflection or is totally reflected the light of light source larger angle is accurate
Straight outgoing.The technical scheme such as CN01805486.2 collimated using total reflection, is that light is imported to into side by the plane of incidence
To curved surface, the outgoing after transmitting total reflection on the curved surface；Reflection collimation is then directly to arrange reflecting surface to be collimated, and can be passed through
Plating reflectance coating realizes direct reflection or irreflexive effect of reflecting surface is realized by spraying white particle.
When realizing that convergence is acted on by fully reflecting surface, the thickness of lens generally requires to be directly proportional to the height of reflecting surface, greatly
The weight and manufacturing cost of lens is increased greatly；And the convergence technology of reflector, have that plated film is inefficient, plating film uniformity is difficult
The problems such as to control；Particularly plastic material the problems such as often result in optical material xanthochromia, affects after high temperature coating process
Light transmittance and reliability.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of lens arrangement of dentation, by straight
The effect that the lens with the flank of tooth reach the reflector for substituting reflecting surface is delivered a child into, the cost both saved also has reached lifting
The purpose of efficiency.
To reach above-mentioned purpose, the technical solution used in the present invention is as follows：A kind of lens arrangement of dentation, comprising radial
The dentalation of extension, it is characterised in that the dentalation of the radial extension is coated on the lateral surface of lens；Each dentation
The appearance profile of structure is identical, generates according to following rule successively,
1) the midpoint O and optical axis I of bus are selected as bus U by a curve for from inside to outside extending；
2) the normal direction vector L of bus midpoint O and tangential direction vector N are planar in the bus；
3) L is formed into two rays L1 and L2 around N directions difference anglec of rotation α and-α；
4) bus U is extended respectively along L1 and L2, is formed and be similar to a V-shape groove；
5) groove is generated into the 3 V-shaped groove-like structures intersected around I anglecs of rotation β and-β；
6) remove the part that two V-shaped grooves of middle V-shaped groove and other intersect, retain remaining part and be institute
State appearance profile.
Further, it is m=360/ β according to the number of circle distribution, and m is integer；Described β is not more than 6 degree.
Further, the part-structure for extending downwards or top is extended upwards is also included from dentalation bottom.
Further, described normal direction is included perpendicular to two contrary directions of tangential direction.
Further, described anglec of rotation α is between 40 degree to 50 degree.
Further, described bus U, the curve tangent line of bottom position and optical axis included angle, cut with the curve of tip position
Line is less than 30 degree with the difference of optical axis included angle.
Beneficial effects of the present invention：
1st, when anglec of rotation α is equal to 45 degree, the function that the dentalation of gained is realized is essentially identical to same mother
The rotationally symmetrical reflecting surface of line U, but preferable mixed light effect can be played；
2nd, when anglec of rotation α deviates 45 degree, the dentalation of gained can suitably be beaten the light that script is converged
Dissipate；45 degree of α deviations are more, then the degree that hot spot is broken up is bigger.While hot spot is broken up, a certain degree of mixed light is remained
Effect, can overcome the problems such as original LED is yellow to be enclosed；
3rd, the level of mixed light is relevant with the number of light source colour discrete type and tooth.For white light encapsulation COB light source and
Speech, 60, the number of teeth mesh (β=6 degree) of setting can reach preferable mixed light level；For RGBW polychromatic sources, 240 are needed
The number of the tooth of (β=1.5 degree) and its above can be only achieved preferable photochromic light mixing effect.

Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings：
Referring to Fig. 1 to Fig. 7, a kind of lens arrangement of dentation of the invention, the dentalation comprising radial extension, its feature
It is that the dentalation of the radial extension is coated on the lateral surface of lens；The appearance profile of each dentalation is identical, according to
It is secondary to generate according to following rule,
1) the midpoint O and optical axis I of bus are selected as bus U by a curve for from inside to outside extending；
2) the normal direction vector L of bus midpoint O and tangential direction vector N are planar in the bus；
3) L is formed into two rays L1 and L2 around N directions difference anglec of rotation α and-α；
4) bus U is extended respectively along L1 and L2, is formed and be similar to a V-shape groove；
5) groove is generated into the 3 V-shaped groove-like structures intersected around I anglecs of rotation β and-β；
6) remove the part that two V-shaped grooves of middle V-shaped groove and other intersect, retain remaining part and be institute
State appearance profile.
Further, it is m=360/ β according to the number of circle distribution, and m is integer；Described β is not more than 6 degree.As schemed
It is to realize that the number of teeth amount of COB mixed lights is the scheme of 60 shown in 9.
Further, the part-structure for extending downwards or top is extended upwards is also included from dentalation bottom.
Further, described normal direction is included perpendicular to two contrary directions of tangential direction.
Further, described anglec of rotation α is between 40 degree to 50 degree.For the mixed light of dentalation, such as Fig. 8 institutes
Show, when α is equal to 45 degree, V-shaped just forms 90 degree of angles.Assume incident illumination deflection be (p, q, r), Jing
The deflection crossed after dentalation is totally reflected twice is (p ,-q ,-r).And pass through the light that common fully reflecting surface reflects, then change
It is changed into (p, q ,-r).As can be seen here, reverse due to many q deflections of this structure, the mixing that will result in light makees
With so as to realize mixed light.In Fig. 8,81 for local V-arrangement light-mixing machine edge line, this edge in the case of the amplification of local
Line is straight line.When α=45 °, every orientation angle can all form direction for the incident ray of (p, q, r) through V-shaped
