Description
Technical field
The present invention relates to LED fields, more specifically to a kind of LED long drive lens.
Background technique
Continue to develop with industry, the leap of technology is broken through, and application is widelyd popularize, and the light efficiency of LED is also constantly mentioning
Height, price constantly drop.The appearance of new combined type tube core also allows the power of single led pipe (module) to be continuously improved.By same
Industry is continually striving to research and develop, the breakthrough of novel optical design, the exploitation of new lamp kind, and the single situation of product is also expected to further
Torsion.The improvement of software is controlled, but also LED illumination use is more convenient.These changes gradually, have all embodied LED hair
Optical diode has a extensive future illumination application.
LED long drive lens are closely connected with LED can enhance the service efficiency and luminous efficiency of light together, can basis
Different effects to change using different lens the optical system of the optical field distribution of LED.
The luminous range of LED light is generally shorter, generally requires the multiple LED light of cooperation and LED long drive lens use, still
Current LED long drive lens light line aggregate capabilities are poor, and range enhancing is small, and effect is general.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of with light-gathering strong, far firing range LED long drive lens.
In order to which the technology and the method that solve the problem above-mentioned use of the invention are as follows:
A kind of LED long drive lens, including lampshade and lens barrel, the lampshade are equipped with reflector, the reflector and lampshade
Between for cassette connect, between the lampshade and lens barrel for cassette connect, the lens barrel top is collocated with Fresnel lens, the spiral shell
To be threadedly coupled between line lens and lens barrel, the lens barrel is internally provided with the first convex lens and the second convex lens, and described first
Convex lens is located at below the second convex lens, and second convex lens upper surface is ladder-like setting, first convex lens and the
Two convex lenses are slidably connected with lens barrel, and the lens barrel inner surface is provided with reflecting mirror, and the reflecting mirror is located at the first convex lens
Lower section, the reflecting mirror are that round table-like setting, the reflecting mirror and lens barrel are arranged for integral type.
Preferably, the Fresnel lens is the setting of Dual-layer optical glass, every layer of optical glass is provided with screw thread, can be with
Light is further assembled, is irradiated with making light uniform concentration, range is promoted.
Preferably, first convex lens and the second convex lens are plano-convex lens setting, light passes through on the two sides of lens
Unirefringence is crossed, light ray parallel convergence is can be, is projected with directional light, can effectively promote intensity of illumination and range.
Preferably, the lampshade is provided with pulling piece, it can be convenient and take apart lampshade and lens barrel.
Preferably, the lens barrel outer surface is wavy setting, it can not only increase frictional force, facilitate and extract lampshade
Come, and coarse surface can make light to the phenomenon that all directions reflection, the light that a part projects lens barrel can be reflected back
In lens barrel, light utilization is improved.
The invention has the benefit that by being provided with Fresnel lens, the first convex lens and the second convex lens light in lens
Two sides pass through unirefringence, can be light ray parallel convergence, projected with directional light, can effectively be promoted and intensity of illumination and be penetrated
Journey.

3, it connects between the reflector 3 and lampshade 1 for cassette, is connected between the lampshade 1 and lens barrel 2 for cassette, the lens barrel 2 pushes up
End is collocated with Fresnel lens 4, is threadedly coupled between the Fresnel lens 4 and lens barrel 2, the lens barrel 2 is internally provided with first
Convex lens 5 and the second convex lens 6, first convex lens 5 are located at 6 lower section of the second convex lens, 6 upper surface of the second convex lens
For ladder-like setting, first convex lens 5 and the second convex lens 6 are slidably connected with lens barrel 2, and 2 inner surface of lens barrel is set
It is equipped with reflecting mirror (not shown), the reflecting mirror is located at 5 lower section of the first convex lens, and the reflecting mirror is round table-like setting, described
Reflecting mirror and lens barrel 2 are integral type setting.
The Fresnel lens 4 is the setting of Dual-layer optical glass, and every layer of optical glass is provided with screw thread (not shown), can be with
Light is further assembled, is irradiated with making light uniform concentration, range is promoted.
First convex lens 5 and the second convex lens 6 are plano-convex lens setting, and light is only primary in the two sides process of lens
Refraction can be light ray parallel convergence, be projected with directional light, can effectively promote intensity of illumination and range.
The lampshade 1 is provided with pulling piece 7, can be convenient and takes apart lampshade 1 and lens barrel 2.
2 outer surface of lens barrel is wavy setting, can not only increase frictional force, facilitate and pull out lampshade 1, and
The light that a part projects lens barrel can be reflected back in lens barrel by the phenomenon that coarse surface can be such that light reflects to all directions,
Improve light utilization.
When in use, LED light is installed on lampshade 1, then lampshade 1 is installed on lens barrel 2.
The invention has the benefit that by being provided with Fresnel lens, the first convex lens and the second convex lens light in lens
Two sides pass through unirefringence, can be light ray parallel convergence, projected with directional light, can effectively be promoted and intensity of illumination and be penetrated
