Abstract

The utility model relates to a lamp shade, in particular to a lamp shade with the light source diffraction function, which comprises a lamp shade and a plurality of grooves on the inner surface of thelamp shade along the inner surface. In the utility model, the grooves can diffract the light source, so when the LED light source is manufactured, a plurality of grooves are made in the inner side ofthe lamp shade, each point light source of the LED light source is diverged by the grooves, so no dizziness is caused. The grooves have extremely high light transmittance, apart from the material, intheory the light transmittance can be higher than 98%, which not only solves the astigmatism, but also solves the low light transmittance caused by other methods to solve the astigmatism.

Description

The trough Scattering lampshade

Technical field

The utility model relates to a kind of lampshade, especially a kind of lampshade with light source scattering function.

Background technology

At present, well-known, because led light source belongs to spot light,, human eye was stimulated strong because point light source light-emitting point light intensity is strong excessively, make human eye that dazzling sensation be arranged when seeing the LED illuminator, the luminous point of LED spot light is dispersed got final product in order only to address this problem need.

Some realizes dispersion effect by prism on the existing lampshade, but because prism is higher to the luminous reflectivity of light source, has reduced the light transmission of lampshade, uses that the brightness of LED lamp can not utilize fully behind this lampshade.

Summary of the invention

It is low that one of the purpose of this utility model provides a kind of reflectivity, the trough Scattering lampshade that light transmission is good.

To achieve these goals, the utility model adopts following technical scheme:

It comprises a lampshade, and its improvement is, is provided with a plurality of arc grooves that distribute along inner surface at the inner surface of lampshade.

Preferably, described a plurality of groove evenly distributes along the lampshade inner surface.

Preferably, described a plurality of groove shapes and size are consistent.

Preferably, described each groove and adjacent grooves coincident.

Preferably, inner surface is upwards derived along edge and is become sidewall, is provided with along the inboard a plurality of sidewall notches that distribute of sidepiece in described interior.

Preferably, described a plurality of sidewall notches evenly distributes along the lampshade inner surface.

Preferably, described a plurality of sidewall notches shape and size are consistent.

The utility model is because groove has disperse function to spot light, so the lampshade inboard at led light source when making led light source makes a lot of grooves, a spot light of satisfying of led light source is dispersed it through a lot of grooves, reach the purpose of not dizzy eye, and the light transmittance of groove is high, the factor of eliminating material, light transmittance can reach more than 98% in theory, has so both solved astigmatic purpose, has solved again because of adopting additive method to solve the low problem of light transmittance that astigmatic problem causes.

Fig. 5 is another plan structure schematic diagram of the utility model second embodiment.

The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.

The specific embodiment

As depicted in figs. 1 and 2, first embodiment of the present utility model is an example with circular lampshade, and it comprises a lampshade 1, and its inner surface at lampshade 1 is provided with along inner surface grooves distributed 11.11 pairs of spot lights of groove have disperse function, so the lampshade inboard at led light source when making led light source makes a plurality of grooves, a spot light of satisfying of led light source is dispersed it through a lot of groove 11, reach the purpose of not dizzy eye, and the light transmittance of groove is higher than existing prism diffusing structure greatly.

The lampshade of present embodiment is not limited to sphere lampshade as shown in the figure, described groove structure is equally applicable to the inner surface of other regular planars or irregular curved surface, simultaneously, the shape of lampshade also is not limited to circle, is other regular geometric shapes or irregular shape.

Because the reasons in structure of lamp, existing lampshade also comprises a sidewall usually except that comprising the bottom, because production is limit, interior can't be on lampshade bottom be equally produced a lot of grooves and its, but also Chinese medicine very of the scattering of side-walls gives above-mentioned reason, second embodiment is proposed on the basis of first embodiment, as shown in Figure 3 and Figure 4, lampshade 1 is upwards derived along edge and is become sidewall 2, is provided with in described sidewall 2 inside along the inboard grooves distributed 21 of sidepiece.

Second embodiment is provided with the scattering that groove carries out light source in lampshade 1 inboard, is provided with groove in sidewall 2 inboards simultaneously light source is carried out scattering, thereby solved the problem of sidewall scattering.

As shown in Figure 5, in order to realize better dispersion effect, described each groove and adjacent grooves coincident.

The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
