Specific embodiment
It is specific below in conjunction with the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
It is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without making creative work, belongs to the utility model
The range of protection.
Below in conjunction with attached drawing, technical solution disclosed in each embodiment of the utility model is described in detail.
Fig. 1-Fig. 7 is please referred to, the utility model embodiment discloses a kind of lens ring of ceiling lamp, and disclosed environment is saturating
The bottom end of mirror has groove 100, and after lens ring is assembled on ceiling lamp, groove 100 is located at the luminous list of ceiling lamp
In member.The inner surface of groove 100 is incidence surface.
Lens ring is annular structural part, and the inner surface of lens ring is inside light-emitting surface, the outside table of lens ring
Face is outside light-emitting surface.It should be noted that the inner surface of lens ring refers to the side on lens ring towards its center
Surface, the outer surface of lens ring refer to the side surface for deviating from its center on lens ring.The inner surface of lens ring
It is away from each other with the outer surface of lens ring.
In lens ring disclosed in the present embodiment, the light in lens ring is entered through in lens ring from incidence surface
Light is projected from inside light-emitting surface and outside light-emitting surface respectively after lens ring reflects, and the light that inside light-emitting surface projects is used
In the center throw to ceiling lamp, i.e., the center throw in the region surrounded towards lens ring.The light that outside light-emitting surface projects
For the projects outside to ceiling lamp, i.e., the direction at the center in the region surrounded away from lens ring projects.
In lens ring disclosed in the utility model embodiment, the inner surface of the groove 100 of the bottom end of lens ring be into
Smooth surface, the light entered in lens ring from incidence surface can be reflected by lens ring, and then can be respectively from lens ring
Inner surface and outer surface project, finally enable to the light distribution of lens ring can be towards throwing except lens ring
It penetrates, and can be towards the center throw of lens ring, it is obvious that this can widen the range of exposures of ceiling lamp.As it can be seen that this is practical
It is existing with the lesser problem of optical range that lens ring disclosed in new embodiment is able to solve current lens.
At the same time, lens ring disclosed in the utility model embodiment can reflect the light of luminescence unit incidence
It is projected respectively towards the lateral direction of the center of lens ring and lens ring afterwards, undoubtedly can make the light distribution of lens ring more
Dispersion, the homogeneity question of the illumination of ceiling lamp caused by avoiding light from excessively concentrating.
In lens ring disclosed in the utility model embodiment, incidence surface may include the first incidence surface 110 and two
Two incidence surfaces 120, wherein the bottom surface of groove 100 is the first incidence surface 110, and the two side walls surface of groove 100 enters light for second
Face 120.In the incidence surface of such structure, when the luminescence unit of ceiling lamp is located in groove 100, luminescence unit can be from groove
Light is injected on the two side walls surface that 100 bottom surface and groove 100 are located at luminescence unit two sides, this can undoubtedly improve the list that shines
The plane of light incidence product of member, so that more light are able to enter in lens ring by light distribution.Above situation can not only improve
Light injection rate, while court respectively is easier after being reflected by lens ring from the light of the two side walls surface incidence of groove 100
It is projected inside and outside to lens ring.
In order to improve the uniformity of light incidence, the cross-sectional shape of the first incidence surface 110 can be circular arc line.Such feelings
Under condition, each position of the first incidence surface 110 is located on curved surface, can preferably realize light incidence, incidence surface is avoided to exist
The homogeneity question of the subsequent light projected after reflection caused by corner angle in structure.Certainly, the first of above structure enters light
Face 110 is easier to form.
Lens ring disclosed in the utility model embodiment can using PC (Polycarbonate, polycarbonate) material,
The transparent materials such as PMMA (polymethyl methacrylate, polymethyl methacrylate) material, glass are made.This is practical
New embodiment does not limit the specific material of lens ring.
As described above, the light that the luminescence unit of ceiling lamp issues is injected in lens ring from incidence surface, annular saturating
It is projected respectively under the light distribution of mirror from inside light-emitting surface and outside light-emitting surface.The reflecting surface structure of lens ring can there are many, only
Meet the projection condition of above-mentioned light.
On the basis for including the first incidence surface 110 and two the second incidence surfaces 120 based on above-mentioned incidence surface, in order to more

It is not provided with the first reflecting surface 200, the top of lens ring has two second corresponding with two the first reflectings surface 200 respectively
Reflecting surface 300, two the first reflectings surface 200 receive the light of corresponding second incidence surface 120 respectively and reflex to light
On corresponding second reflecting surface 300, the first reflecting surface 200 on the inside of lens ring passes through with the second reflecting surface 300
Inside light-emitting surface 400 is connected, and the first reflecting surface 200 on the outside of lens ring is gone out by outside with the second reflecting surface 300
Smooth surface 500 is connected.
In the specific course of work, from the incident some light of the first incidence surface 110 and from second incidence surface
Incident light can be reflected by one of those the first reflecting surface 200 on 120, and be reflected light by first reflecting surface 200
On to corresponding second reflecting surface 300, finally projected by the second reflecting surface 300 towards the inner or outer side of lens ring.On
State in structure, to lens ring inside and outside the structure of reflection light respectively include the first reflecting surface 200 matched and
Two reflectings surface 300, this undoubtedly can preferably realize the distribution of light, and in specific design process, designer can pass through
Two the first reflectings surface 200 and two the second reflectings surface 300 are designed, thus to adjust the light distribution amount inside and outside lens ring.
In order to be better achieved the projection of light, inside light-emitting surface 400 and outside light-emitting surface 500 are parallel and towards phase
Instead, that is to say, that inside light-emitting surface 400, towards opposite direction throw light, and then is advantageously formed with outside light-emitting surface 500
More match optical range greatly.
In the present embodiment, the first incidence surface 110 can be the plane of symmetry, and symmetrical incidence surface, which advantageously forms, symmetrically matches
Light, certainly, symmetrical light distribution also rely on the positional relationship of two first reflectings surface 200 and two the second reflectings surface 300.For example,
First incidence surface 110 is arcwall face.Above-mentioned two second reflecting surface 300 can have certain gradient, and intersect, such feelings
It under condition, is more advantageous to the light projected in lens ring and spreads in the horizontal plane, be also easier to realize the adjusting of light-emitting angle.
In preferred scheme, the first reflecting surface 200 and the second reflecting surface 300 all can be fully reflecting surface in such cases can be into one
Reflecting effect of the step optimization to light.
In preferred scheme, two the second reflectings surface 300 intersect and form indent to be recessed in the top of lens ring, such as
