Description
Technical field
The utility model relates to LED lens fields, more particularly, to a kind of focusing LED lens of linear light source.
Background technique
As the technology of LED develops, LED is used in more and more fields, and there are many advantage of LED, and energy-saving and environmental protection are maximum
Advantage.Other than the application in lighting area, the field that many spies adopt also has obtained being widely applied very much LED.The application of LED
Also increasingly paid attention to, LED substitutes traditional incandescent lamp, has following various advantages: first is that energy conservation: same light
Effect, LED is than conventional incandescent streetlamp energy-saving 70~80%；Second is that environmentally friendly: LED material does not simultaneously contain evil metal " mercury ", and due to power consumption
Measure small, energy saving, and the another embodiment of environmental protection；Third is that the LED long-life, traditional incandescent lamps service life was on 2000 hours left sides
The right side, and the service life of LED was at 50,000 hours or more；
For the article of very thin strip, irradiation has reformed into problem.E.g. optical fiber cable, cable size only have milli
The cover of meter level, the light energy on unit area is extremely important, while being also technological difficulties, and many past technology is all
The design of optical concentration lens is done on single LED light source, but is often produced little effect, and effect is undesirable.
Utility model content
The utility model is to overcome above situation insufficient, it is desirable to provide a kind of technical solution that can solve the above problem.
A kind of focusing LED lens of linear light source, comprising: lampshade plate, the lampshade plate are that transparent pane shape plate turns lampshade, institute
State and be provided with a positive lens and two side lens on lampshade plate, two side lens are set to the two sides of positive lens, side lens with
Positive lens is that semi-cylindrical, side lens and the length of positive lens and the long side length of lampshade plate are identical, the lampshade plate lower end
There are two oblique incidence face and normal incidence face, two oblique incidence faces to be set to normal incidence face two sides for setting, and oblique incidence face is set to side
The lower end of lens, normal incidence face are set to the lower end of positive lens, and the refraction point of positive lens is vertical with the incidence point in normal incidence face, side
The refraction point of lens and the incidence point in oblique incidence face are vertical.
As a further solution of the present invention: the lampshade plate, side lens are having for the high grade of transparency with positive lens
Machine silica gel is made.
As a further solution of the present invention: the oblique incidence face and lampshade plate lower end are in 166.37 ° of angles.
As a further solution of the present invention: the refractive direction phase of the positive lens and the refraction point of two side lens
Together, a focal spot is formed.
Compared with prior art, the utility model has the beneficial effects that lampshade and lens are made into integral LED module；The
Two, the structure of lens is strips, is specifically designed for the irradiated body of small diameter；Third, according to light source with shone
The optimum combination of the distance and most effective light intensity optically focused distance penetrated, so that it is determined that the optical angle of lens.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model side view.
In figure: 1, lampshade plate, 2, side lens, 3, positive lens, 4, normal incidence face, 5, oblique incidence face.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Please refer to Fig. 1~2, in the utility model embodiment, a kind of focusing LED lens of linear light source, comprising: lampshade plate 1,
The lampshade plate 1 is that transparent pane shape plate turns lampshade, and a positive lens 3 and two side lens 2 are provided on the lampshade plate 1,
Two side lens 2 are set to the two sides of positive lens 3, and side lens 2 and positive lens 3 are semi-cylindrical, side lens 2 and positive lens 3
Length it is identical as the long side length of lampshade plate 1,1 lower end of lampshade plate setting there are two oblique incidence face 5 and normal incidence face 4,
Two oblique incidence faces 5 are set to 4 two sides of normal incidence face, and oblique incidence face 5 is set to the lower end of side lens 2, and normal incidence face 4 is set to
The refraction point of the lower end of positive lens 3, positive lens 3 is vertical with the incidence point in normal incidence face 4, the refraction point of side lens 2 and oblique incidence
