Abstract
The utility model relates to a LED candle lamp lens, including the lens body, lens body upper portion is the round platform form, and open at the top has circular recess, circular recess bottom is the convex lens of evagination, the side of circular recess is the curved surface of level and smooth evagination, the opening diameter of circular recess is the same with lens body top surface diameter. The utility model discloses a simple structure has realized the requirement of candle lamp grading lens, utilizes lens self optical characteristic to carry out full reflection and refraction to light, and the light that sends the light source carries out the grading, the plastic is handled, realizes the wide -angle light -emitting, and production simple process practices thrift manufacturing cost.
Description
Technical field
The utility model relates to field of illuminating lamps, particularly relates to a kind of LED candle lamp lens.
Background technology
Existing LED candle lamp light fixture adopts refraction and total reflection to carry out shaping to light usually, for the candle lamp light fixture adopting refraction to carry out light shaping, because common refraction and total reflection structure can only carry out shaping to LED section light, and shaping effect is not good enough, the wide-angle shaping effect of middle emergent light is very not good, and light can direct transmission, makes most of light concentrate on low-angle region, and wide-angle region light is little, candle lamp effect is caused to be not so good as actual candle; Middle power chip paster LED candle lamp is applicable to for other, simple structure can not be adopted to solve the few problem of wide-angle direction light accounting.
Utility model content
The utility model aims to provide a kind of LED candle lamp lens, carries out luminous intensity distribution, Shape correction, realize wide-angle bright dipping to the light that light source sends, and structure is simple, and production technology is simple, saves production cost.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of LED candle lamp lens, comprise lens body, described lens body top is round table-like, top has circular groove, be the convex lens of evagination bottom described circular groove, the side of described circular groove is the curved surface of level and smooth evagination, and the opening diameter of described circular groove is identical with lens body end face diameter.
Preferably, the curvature of described curved surface reduces from bottom to top gradually.
Preferably, the end face diameter of described lens body bottom is greater than basal diameter, lens body lower side is the smooth surface of evagination, and the end face diameter on described lens body top is greater than the end face diameter of lens body bottom, the axis on lens body top and the dead in line of lens body bottom.
Further, described convex lens are massif shape.
Further, the bottom peripheral edge on described lens body top is equidistantly provided with four assembly walls.
Compared with prior art, the utility model has following beneficial effect:
The utility model adopts simple structure to achieve the requirement of candle lamp light-distribution lens, utilize lens own optical characteristics be totally reflected light and reflect, luminous intensity distribution, Shape correction are carried out to the light that LED light source sends, realizes wide-angle bright dipping, production technology is simple, saves production cost.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of LED candle lamp lens disclosed in the utility model, comprise lens body, described lens body top 1 is round table-like, top has circular groove, be the convex lens 3 of massif shape bottom circular groove, convex lens 3 can be totally reflected the light processing and beat on convex lens 3, the side of circular groove is the curved surface of level and smooth evagination, the slope of curved surface reduces from bottom to top gradually, the opening diameter of circular groove is identical with lens body end face diameter, the end face diameter of lens body bottom 2 is greater than basal diameter, the side of lens body bottom 2 is the smooth surface of evagination, the end face diameter on lens body top 1 is greater than the end face diameter of lens body bottom 2, the axis on lens body top 1 and the dead in line of lens body bottom 2.Preferably, bottom surface, lens body bottom 2 is provided with four light sources 5, and light source 5 is equidistantly located at circumferentially same; The bottom peripheral edge on lens body top 1 is equidistantly provided with four assembly walls 4.
The first scioptics body lower part 2 of the light that light source 5 sends reflects, some light scioptics body upper part 1 total reflection wherein supplements high angle scattered light, another part is then totally reflected to the side of lens body top 1 circular groove by convex lens 3, make illumination to wide-angle direction by the reflective functions of circular groove side again, large angle illumination is provided.The candle lamp lens that the utility model provides, utilizes lens own optical characteristics be totally reflected light and reflect, carries out luminous intensity distribution, Shape correction to the light that LED light source sends, rising angle is large, and structure is simple, and production technology is simple, and production cost is low.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
