Description

A kind of COB lens

Technical field

The utility model belongs to technical field of lamps, refers in particular to a kind of COB lens.

Background technology

COB light source have many advantages, such as high colour developing, high-luminous-efficiency, low thermal resistance, without hot spot, energy conservation and environmental protection, in commercial lighting With museum illumination etc. some fields more demanding to the illuminating effects such as hot spot, photochromic, illumination, generally use COB light source conduct The light emitting source of lamps and lanterns is subject to secondary optical design, and to reach lighting requirement, requirement of the present room lighting to lamps and lanterns is increasingly It is high, it is desirable that its hot spot is uniform, no macula lutea.Lamps and lanterns all include generally light source and lens, since the light that light source itself sheds can be coloured Difference, it is therefore desirable to which lens reduce its aberration, currently, the commercially available lamps and lanterns hot spot comprising COB lens is not uniform enough, there are macula luteas And dazzle, and routine COB lens appearance homogeneities are more serious, can not give the novel feeling of customer, cannot still meet market visitor The demand at family.

Utility model content

The purpose of this utility model is to provide a kind of uniformity that can improve hot spot, anti-dazzle and without the COB of macula lutea Lens.

In order to achieve the above objectives, the solution of the utility model is：

A kind of COB lens are set to the luminous place of COB light source, including：Lens cup body and upper surface by the lens cup body The minute surface of recessed formation, the front compound eye structural that the center projection of the minute surface is made of multiple pearl points, the diverging of the pearl point Angle is 137.5 degree, and the lower face of the lens body is convexly equipped with the accommodating space for accommodating COB light source, the lens cup body Outer surface be set as the TIR scale and shell structures of prismatic.

The pearl point is spiral distribution.

The area of the upper surface of the lens cup body is more than the area of the lower face of lens cup body.

The marginal water plano-convex of the upper surface of the lens cup body is equipped with flange.

The back side of the flange is polygon pearl face.

The pearl face is irregular hexagon.

After adopting the above technical scheme, the utility model is by the minute surface of the recessed formation in the upper surface of lens cup body, and It is 137.5 degree in the angle of divergence of the front compound eye structural that the center projection of the minute surface is made of multiple pearl points, the pearl point, this Angle is Golden Angle, so as to so that the hot spot come out from front compound eye structural is uniform, no macula lutea, and fit through the lens The TIR scale and shell structures that the outer surface of cup body is set as prismatic achieve the effect that optics calculus according to total reflection principle, to The uniformity of hot spot can be further increased, anti-dazzle is realized without the bad hot spot such as macula lutea, while the illuminating effect played A kind of novel mode of appearance is provided.

Specific implementation mode

To reach above-mentioned purpose and effect, technological means and construction used by the utility model, hereby draw with regard to this practicality Novel its feature of preferred embodiment elaborate and function are as follows, are understood completely with sharp.

TIR (Total Internal Reflection) lens refer to the lens system designed using inner full-reflection principle System, because the characteristic of its high-effective concentration is used widely.

Shown in please referring to Fig.1 to Fig.3, the utility model discloses a kind of COB lens, is set to the luminous place of COB light source 6, Including：The minute surface 2 of lens cup body 1 and the recessed formation in upper surface by the lens cup body 1, the center projection of the minute surface 2 by The angle of divergence of the front compound eye structural 3 of multiple pearl point compositions, the pearl point is 137.5 degree, this angle is Golden Angle, the lens The lower face of ontology 1 is convexly equipped with the accommodating space 5 for accommodating COB light source 6, and the outer surface of the lens cup body 1 is set as rib The TIR scale and shells of four prismatics may be used in the outer surface of the TIR scale and shell structures of shape, the lens cup body 1, can also be other more ribs Prismatic TIR scale and shells, the TIR scale and shells could also say that crystal type, and the pearl point is spiral distribution, generates positive and negative two groups of spiral shells The effect of rotation.

Furthermore the area of the upper surface of the lens cup body 1 is more than the area of the lower face of lens cup body 1, to expand The irradiated area of light source.

Secondly, the marginal water plano-convex of the upper surface of the lens cup body 1 is equipped with flange 4, is easily installed.The flange 4 The back side is polygon pearl face, and in the present embodiment, the pearl face is irregular hexagon, to keep the utility model whole more beautiful It sees.

It please refers to shown in Fig. 4, when using the utility model, user can be solid in the lower face of the lens cup body 1 If a COB light source holder 7, the middle part of the light source bracket 7 is equipped with a through-hole for housing COB light source 6, and the COB light Source 6 is directed at accommodating space 5.

In conclusion the utility model is by the minute surface 2 of the recessed formation in the upper surface of lens cup body 1, and in the mirror The angle of divergence of the front compound eye structural 3 that the center projection in face 2 is made of multiple pearl points, the pearl point is 137.5 degree, this angle is Golden Angle, the front compound eye structural 3 grows the shape of base using sunflower is imitated, so as to so as to go out from front compound eye structural 3 The hot spot come is uniform, no macula lutea, and fits through the outer surface of the lens cup body 1 and be set as the TIR scale and shell structures of prismatic, root According to total reflection principle, achieve the effect that optics calculus, so as to further increase the uniformity of hot spot, anti-dazzle is realized Without the bad hot spot such as macula lutea, the illuminating effect that the utility model can play while, provides a kind of novel mode of appearance.

The technology contents and technical characterstic of the utility model have revealed that as above, the quantity of the building block of the utility model is simultaneously It is not limited with above-mentioned, those skilled in the art is still potentially based on the announcement of the utility model and makees various new without departing substantially from this practicality The replacement and modification of type creation spirit.Therefore, the scope of protection of the utility model should be not limited to disclosed in embodiment, and should include Various replacements and modification without departing substantially from the utility model, and covered by claims.
