Abstract
The utility model discloses a LED secondary lens, including the lens body, the upper portion of the inside center pin of this lens body is equipped with out light groove, the lower part is equipped with into light groove, the upper portion that goes out light groove is equipped with length and is greater than the play plain noodles intos light groove length, and the perpendicular below at the both ends on this plain noodles all is equipped with outside convex step perpendicularly, the below of step with go into light groove's below and connect a formation arc refracting surface. The utility model discloses a novel structure utilizes transparent silica gel material injection moulding to form, has that the luminousness reaches 90% or more and be colourless poor, and temperature resistant cold resistance is good, and product property can stabilize advantages such as long service life.
Description
Technical field
This utility model relates to lens technologies field, specifically a kind of LED secondary lens.
Background technology
The secondary lens of tradition LED, glass or perspex material often, the problems such as it is high that lens exist luminous efficiency, poor heat resistance, and tolerance to cold, resistance to ozone and resistance to atmospheric aging are poor, range has limitation.It addition, existing secondary lens often there is also, structure is complicated, properties of product are unstable, light transmittance is low, temperature tolerance is poor, there is the defects such as aberration.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, it is provided that a kind of LED secondary lens, has light transmittance and reaches more than 90% and no color differnece, and heatproof tolerance to cold is good, and properties of product are stable, service life the advantage such as length.
For achieving the above object, technical scheme provided by the utility model is:
A kind of LED secondary lens, it includes lens body, the top of the inside center axle of this lens body is provided with light output groove, bottom is provided with into light groove, the top of described light output groove is provided with length and is more than the exiting surface into light slot length, the vertical lower at the both ends of this exiting surface is equipped with the most outwardly step, the lower section of described step with described enter light groove lower section be connected formation one arc plane of refraction.
Further, the cross section of described exiting surface is plane.
Further, the described cross section entering light groove and light output groove is rectangle.
Further, the described left bottom entering light groove is provided with locating dowel.
Further, the described bottom right side entering light groove is provided with a rectangular opening.
Further, the upper edge lengths of described step is less than lower edge lengths.
Further, the length of described light output groove and the most respectively to length and the height entering light groove described in should be less than.
Further, described lens body is transparent silica gel material.
Further, described lens body by existing Shooting Technique machine-shaping in one.
Compared with prior art, the beneficial effects of the utility model are:
The LED secondary lens that this utility model provides, structure is unique, transparent silica gel material is utilized to be molded into lens arrangement, not only increase the light transmittance of lens, its lens retroreflective rate reaches more than 90%, entirely without aberration under high transmission rate, and thermostability and tolerance to cold are good, resistance to ozone and resistance to weathering are good, can be at-60 DEG C with life-time service at a temperature of down to more than 250 DEG C, lens products stable performance, life-span is longer, can relax the use environmental field of LED secondary lens, reasonable in design, practical, it is more widely applied.
Below in conjunction with the accompanying drawings with embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is lens arrangement schematic diagram of the present utility model.
Detailed description of the invention
See Fig. 1, the LED secondary lens that the present embodiment provides, it includes lens body 1, the top of the inside center axle of this lens body 1 is provided with light output groove 5, bottom is provided with into light groove 7, the top of its light output groove 5 is provided with length and is more than the exiting surface 3 into light groove 7 length, the vertical lower at the both ends of this exiting surface 3 is equipped with the most outwardly step 4, and the lower section of step 4 is connected formation one arc plane of refraction 6 with the lower section entering light groove 7；The cross section of exiting surface 3 is plane；The cross section entering light groove 7 and light output groove 5 is rectangle；The left bottom entering light groove 7 is provided with locating dowel 2, is used for installing fixing lens body；The bottom right side entering light groove 7 is provided with a rectangular opening 8, and for mounted LED lamp bulb, the upper edge lengths of step 4 is less than lower edge lengths, the length of light output groove 5 and the most respectively to should be less than the length and highly into light groove 7；Lens body is transparent silica gel material, and this transparent silica gel material has the features such as light transmission is good, temperature tolerance tolerance to cold is good, and lens body uses existing Shooting Technique machine-shaping in one, and technique is accurate, and properties of product are stable.
In actual applications, LED is arranged on the bottom of lens body 1, part light is by entering light groove 7, it is refracted on outer arcuate plane of refraction 6, going out from exiting surface 3 through multiple total reflection afterwards, a light is shot out finally by light output groove 5 and exiting surface 3 by the inner utilization lens principle in lens body 1.
The announcement of book and teaching according to the above description, above-mentioned embodiment can also be changed and revise by this utility model those skilled in the art.Therefore, this utility model is not limited to detailed description of the invention disclosed and described above, should also be as falling in scope of the claims of the present utility model to modifications and changes more of the present utility model.
