Abstract

The utility model relates to the technical field of lamp covers, in particular to an LED lamp cover. Two or more protruded strips are arranged on the inner surface of a lamp cover body of the LED lamp cover, cross section faces of the protruded strips are in arc face structures protruding to the inner surface of the lamp cover body, so that the cover body has an effect of a convex lens, on one hand, diffusion effect of light can be improved the light is soft and is not dazzling, on the other hand, a user cannot see related components in the LED lamp cover, and the LED lamp is attractive in appearance. Simultaneously, compared with a scheme that a diffusion agent is added into a raw material for producing the cover body so as to achieve a light diffusion effect, the diffusion agent is not needed to be added, and production cost is also reduced.

Description

A kind of LED lampshade

Technical field

The utility model relates to the lampshade technical field, particularly a kind of LED lampshade.

Background technology

Along with being becoming tight the day of world energy sources and to the popularization of green illumination, the LED lamp low, that the life-span is grown that consume energy receives increasing concern, its promoted extension is also more and more wider.

In the existing LED fluorescent tube, major part is selected the Transparent lamp shade of high transmission rate, and the fluorescent tube that this lampshade is worked it out can be seen the lamp pearl, and is not very dazzling, dizzy easily, attractive in appearance and do not meet human requirement to light.

For addressing the above problem, the method that adopts at present is to add diffusant in the material of making this lampshade, so that the user can directly not see the devices such as LED lamp pearl in the lampshade, thereby strengthen the aesthetic of this LED lamp, yet, because the interpolation of diffusant, so that the total light flux of LED fluorescent tube has reduced by 30%, to such an extent as to reduced the illuminating effect of LED fluorescent tube, also increased production cost simultaneously.

Therefore, be badly in need of a kind of LED lampshade of exploitation, it does not add diffusant on the one hand, and on the other hand, the user can not see the related device in the LED lampshade clearly yet, can not affect light transmittance and the illuminating effect of this LED lampshade simultaneously.

The utility model content

There is above-mentioned problem in the utility model in order to solve present LED lampshade, and a kind of LED lampshade that provides, the illuminating effect that this LED lampshade neither can reduce the LED fluorescent tube can make again the user not see the interior related device of LED lampshade.

For reaching above-mentioned functions, the technical scheme that the utility model provides is:

A kind of LED lampshade comprises lampshade, is provided with two or more convex stripe at the inner surface of described lampshade, and the cross section of described convex stripe is the globoidal structure to the inner surface projection of described lampshade.

Preferably, the height of the globoidal structure of described projection is 0.5mm～1.5mm.

Preferably, described convex stripe is continuously arranged structure.

Preferably, described convex stripe is spaced structure.

The beneficial effects of the utility model are: the convex stripe that is provided with two or more by the inner surface at the lampshade of LED lampshade, the cross section of described convex stripe is the globoidal structure to the inner surface projection of described lampshade, thereby make lampshade play the effect of convex lens, the diffusion effect that therefore can improve on the one hand light makes light soft not dazzling, the user does not see again the related device in the LED lampshade on the other hand, so that the LED lamp is attractive in appearance, simultaneously need not again to add diffusant, therefore reduced production cost.

Fig. 2 is the structural representation of embodiment two.

The specific embodiment

Be further elaborated below in conjunction with accompanying

drawing

1 and 2 pairs of the utility model of accompanying drawing:

Embodiment one:

A kind of LED lampshade as shown in Figure 1 comprises lampshade 1, is provided with two or more convex stripe 2 at the inner surface of lampshade 1, and the cross section of convex stripe 2 is the globoidal structure 21 to the inner surface projection of lampshade 1.Owing to have convex stripe 2 in order to make things convenient for moulding in the lampshade 1, lampshade 1 adopts the mode processing and manufacturing of PC particle extrusion molding to form in this example.

Because the wall thickness of lampshade 1 is generally 0.5～1.5mm, for improving the extrusion molding yields, reduction causes the even injection defect that causes of lampshade 1 wall unevenness owing to have convex stripe 2 in the lampshade 1, and the height of the globoidal structure 21 of projection is preferably 0.5mm～1.5mm.

The quantity of convex stripe 2 can be adjusted as required flexibly, as long as can go out the light scattering that the LED fluorescent tube produces, improves light transmittance.Simultaneously, because the effect of lampshade 1 internal projection striped 2 so that the user in the process of using, can very clearly not observe the related devices such as LED lamp pearl in the lampshade 1 from the outside, thereby has improved the aesthetics of LED fluorescent tube.In specific design of the present utility model, for increasing scattering, light transmission and observable not, the continuously arranged frame mode that a plurality of convex stripes 2 adopt as shown in Figure 1.

For shape and the structure of convex stripe 2, flexible design as required, the cross section of convex stripe 2 both can be circular arc, also can be other suitable shape, as long as satisfy astigmatism and prevent that from the outside direct clear view is to inner related device.

Embodiment two:

In the present embodiment, except the arrangement mode of convex stripe 2, remaining structure is all identical with embodiment one, only the different part of structure is described in the present embodiment, all the other same sections no longer describe in detail, and as shown in Figure 2, a plurality of convex stripes 2 adopt spaced structure.

In sum, a kind of LED lampshade of the present utility model, two or more convex stripe 2 is set at the inner surface of the lampshade 1 of LED lampshade, the cross section of convex stripe 2 is the globoidal structure 21 to the inner surface projection of lampshade 1, many convex stripes 2 are at the inner surface continuous arrangement of lampshade 1 or be spaced, thereby make lampshade 1 play the effect of convex lens, the diffusion effect that therefore can improve on the one hand light makes light soft not dazzling, can make again on the other hand the user not see the interior related device of LED lampshade, so that the LED lamp is attractive in appearance, simultaneously need not again to add diffusant, therefore reduced production cost.

The above embodiment, it is preferred embodiments of the present utility model, be not to limit practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, all should be included in the utility model patent claim.
