Abstract
The utility model discloses a lens with plain noodles is gone into to exchange formula, including lens body and ligand, the lens body is formed with the mounting groove toward interior caving in in the middle of the bottom, the ligand install in in the mounting groove, the appearance and the mounting groove phase -match of ligand, the ligand is from bottom toward interior sunken being formed with into the plain noodles, just be provided with sunken draw -in groove on the mounting groove lateral wall bottom, correspond, the ligand extends outside the outer wall is past has the fixture block, the fixture block card is gone into in the draw -in groove to when the LED lamp need obtain different projection angle, only need to be changed that it is passable to be provided with different ligands of going into plain noodles, the whole lens that do not need to be changed that is to say, the utility model discloses an it can exchange to go into the plain noodles to the cost is reduced.
Description
Technical field
The utility model relates to lens, particularly relates to a kind of lens with interchangeable incidence surface.
Background technology
Lens are generally used for LED, and LED lamp bead, as the light source of light fixture, usually needs to use lens guide or gather light, thus forms certain crevice projection angle.And different crevice projection angles is all realized by the incidence surface of different curvature, because the light that the incidence surface of different curvature can produce different refraction angles is mapped on the fully reflecting surface of lens, then is shot out by fully reflecting surface, thus obtains different crevice projection angles.In traditional design, incidence surface is all be integrally formed at lens, is namely the incidence surface forming certain curvature from the bottom of lens toward sunken inside, if expect different ray cast angles, then must changes whole lens, thus cause the increase of cost.
Utility model content
The purpose of this utility model is to provide a kind of lens with interchangeable incidence surface, and its incidence surface and lens body are provided separately.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of lens with interchangeable incidence surface, comprise lens body and ligand, described lens body is formed with mounting groove toward sunken inside in the middle of bottom, described ligand is installed in described mounting groove, and profile and the mounting groove of described ligand match, and described ligand is formed with incidence surface from bottom toward sunken inside, and described mounting groove sidewall bottom is provided with the draw-in groove of depression, corresponding, described ligand is extended with fixture block outward from outer wall, and described fixture block snaps in draw-in groove.
Described mounting groove is cylindrical, and it is cylindrical that the profile of described ligand is also set to match.
Communicate with mounting groove inside described draw-in groove, corresponding, described fixture block is past extension bottom ligand outer wall.
Described incidence surface is truncated cone-shaped.
Described incidence surface is circular arc.
The beneficial effects of the utility model are: lens body and the incidence surface of the utility model lens are provided separately, instead of be integrally formed, thus when LED needs to obtain different crevice projection angles, only need to change the ligand being provided with different incidence surface just passable, do not need to change whole lens, that is, incidence surface of the present utility model can exchange, thus reduces 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 drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1,2,3,4,5, the lens that the utility model has interchangeable incidence surface comprise lens body 1 and ligand 2, described lens body 1 is formed with mounting groove 11 toward sunken inside in the middle of bottom, described ligand 2 is installed in described mounting groove 11, profile and the mounting groove 11 of described ligand 2 match, described ligand 2 is formed with incidence surface 21 from bottom toward sunken inside, and described mounting groove 11 sidewall bottom is provided with the draw-in groove 12 of depression, corresponding, described ligand 2 is extended with fixture block 22 outward from outer wall, and described fixture block 22 snaps in draw-in groove 12.
In the present embodiment, preferably, described mounting groove 11 is cylindrical, and so, the profile of described ligand 2 also arranges match cylindrical, and the cylindrical lens body 1 that can make is more convenient with the installation of ligand 2.In other embodiments, described mounting groove 11 and the profile of ligand 2 can be set to other shapes of mating arbitrarily.
Communicate with mounting groove 11 inside described draw-in groove 12, corresponding, described fixture block 22 is past extension bottom ligand 2 outer wall.Fixture block 22 and the setting coordinated of draw-in groove 12, be in order to ligand 2 is more convenient with the assembling of lens body 1 on the one hand, and when changing ligand 2, can act on fixture block 22, and being not used as incidence surface 21, thus can avoid the wearing and tearing of incidence surface 21.
As Fig. 3,4,5 be depicted as described in ligand 2 first embodiment, in this embodiment, described incidence surface 21 is truncated cone-shaped.
Be described ligand 2 ˊ second embodiment as shown in Figure 6,7, the different shapes being incidence surface 21 ˊ of this embodiment and the first embodiment, in the present embodiment, described incidence surface 21 ˊ is circular arc.
In other embodiments, described incidence surface 21 can have any shape, thus forms the incidence surface 21 of any different curvature.
As mentioned above, lens body 1 and the incidence surface 21 of the utility model lens are provided separately, instead of be integrally formed, thus when LED needs to obtain different crevice projection angles, only need to change the ligand 2 being provided with different incidence surface 21 just passable, do not need to change whole lens, that is, incidence surface 21 of the present utility model can exchange, thus reduces cost.
In more than describing, orientation take Fig. 2 as reference, and the upper of Fig. 2 is above-mentioned bottom.
