The lens structure is provided with a lens main body, wherein the lens main body is provided with a first surface and a second surface, a ring curve is adjoined between the first surface and the second surface, the ring curve is combined by two symmetrical arcs, the overlapped representing line of the two arcs is provided with a first end point, an intermediate point and a second end point, and a multi-focus curved surface is formed by the first surface. Therefore, the light radiation route and shape can be controlled by the multi-focus curved surface formed by the first surface of the lens main body so as to adapt to environments with different requirements.

Description

Illuminating lens arrangement

Technical field

The present invention relates to a kind of illuminating lens arrangement, refer to the multifocal curved surface formed by means of ring Curves adjacent between the first surface of lens body and second surface especially, course and the light type of light irradiation can be controlled.

Background technology

The light source of current lighting uses LED mostly, LED has energy saving, the long-time advantage used, when but wish improves the brightness of LED, the light fixture of more LED number can be adopted, seen by outside, most bright spots can be produced, it is how honorable that multiple bright spot makes photographed object produce, and then produce fuzzy sense, easily causes eye fatigue, therefore, lighting fit lens uses is the optimum method that LED increases brightness.

And TaiWan, China No. M343112 " LED lamp of replaceable lens " Patent Case, it mainly installs a light-emitting diode component in a Lamp cup, this Lamp cup rear end is provided with in one the lamp socket establishing circuit board, the Lamp cup lid that one has light hole is provided with in this Lamp cup front end, light hole like this is installed disconnectable lens and is positioned at light emitting diode front end, these lens can be moulding or the color of Suresh Kumar, make this LED lamp that the different lens of replacing can be relied on to provide diversified decorative lighting and polynary outward appearance.

Above-mentioned existing lens are convex lens, the light utilizing the convex lens of different radian that light emitting diode is projected changes to some extent, but it changes howsoever, the distance of throw light, size can only be changed, path for light cannot have variability, such as: car light or dynamo lighting set need downward light to illuminate road surface, but it is the benchmark of scattering that current light is still with ring, therefore the light source loss of half is had above light fixture, even affect the sight line of user, cause the danger of driving.

Summary of the invention

The present invention can solve that existing illuminating lens are difficult to accurately control the scope of light, the light source of brightness and projection does not have the problems such as change.

For achieving the above object, the technical solution used in the present invention is:

A kind of illuminating lens arrangement, be provided with lens body, this lens body has a first surface and a second surface, it is characterized in that: between this first surface and second surface, adjoin a ring curve, this ring curve is that two symmetrical camber lines combined, the superimposed line segment presented of these two camber lines has one first end points, a mid point and one second end points, makes this first surface form multifocal curved surface.

Described illuminating lens arrangement, wherein: the first end points to the mid point of this lens body is one first arc tune, this mid point to this second end points is a second arc tune extended back, and this first arc tune is more more straight than this second arc tune.

Described illuminating lens arrangement, wherein: the first end points to the mid point and the second end points to mid point of this lens body is two symmetrical arc tunes extended to mid point.

Described illuminating lens arrangement, wherein: the medial surface of this lens body is provided with an alcove.

The illuminating lens arrangement of the present invention, can be incorporated on light fixture by this lens body, this light fixture is provided with lamp socket and LED light source, and this light fixture is the various lightings such as car light, street lamp, flashlight, searchlight.

The illuminating lens arrangement of the present invention, its advantage is as follows:

1. use LED light source, no matter be monocrystalline LED light source or polycrystalline LED light source, have the multifocal curved surface that the ring Curves by lens body is formed, and effectively light source is uniformly distributed, and effectively control to desired position, do not need matte auxiliary generation "cut-off"line, and lose overall brightness.

2. use the present invention can reduce the usage quantity of LED light source, to reduce costs.

3. use LED light source can reduce thermal source to produce, extend the life-span of LED, can product competitiveness be improved.

4. the multifocal curved surface that formed of the ring Curves of scioptics body, can control light type is ellipse, round or semi-circular, to be useful in the environment of various different demand.

5. use lens body of the present invention to be effectively uniformly distributed by light source, the photographed object that can improve general multiple light courcess produces the fuzzy sense of many shadows, makes eyes unlikely too tired.
