The utility model is solve the problems of the technologies described above the technical scheme taked to be:
Described in LED daylight lamp cover of the present utility model, fluorescent lamp shade is Transparent lamp shade, the surrounding of described fluorescent lamp shade is provided with the outer for installing, the width of described fluorescent lamp shade is 90 ~ 110 ㎜, the cross section of described fluorescent lamp shade is circular arc, the action of described fluorescent lamp shade is 15 ~ 20 ㎜, the outer surface of described fluorescent lamp shade is circular arc light face, the inner surface of described fluorescent lamp shade is provided with wave stripe along its length, the groove that wave stripe is circular arc by many sliver transvers sections is connected in sequence, cross section is the radius of the groove of circular arc is 1.5 ~ 1.6 ㎜, the thickness of described fluorescent lamp shade is 0.9 ~ 1 ㎜.
The beneficial effects of the utility model are:
The inner surface of LED daylight lamp cover of the present utility model is provided with wave stripe along its length, each groove part is equivalent to one group of convex lens, the material that light transmittance is high, refractive index is larger is selected can effectively to stop blue light to penetrate outside, wherein there is some blue light to penetrate with the angle less with lampshade face, because blue light is as easy as rolling off a log scattering in communication process, adopt LED daylight lamp Lacquer finish line of the present utility model not direct irradiation enter the eyes of people, on eyesight without impact;
LED daylight lamp cover of the present utility model is by the wave stripe of the inner surface of fluorescent lamp shade, according to the length of blue light wavelength, easily produce the feature of total reflection and easy scattering when injecting air from medium, the high energy blue light maximum to eyesight influence in spectrum can be filtered by lampshade; The visible ray that light source is launched through lampshade of the present utility model, by filtering, refraction and dry penetrate after become soft, fundamentally eliminate blue light and dazzle light, therefore lampshade of the present utility model has very large protective effect to eyesight; LED daylight lamp cover of the present utility model, light transmittance is high, light source utilization rate is high;
Lampshade of the present utility model is applied on existing LED classroom lamp, can be widely used in classroom and the office lighting of middle and primary schools, ambient light can be made even, soft, the available protecting eyesight of user.

Operation principle:
First the light that light source sends just will can be diffused in space by lampshade and go, and first effect of lampshade is exactly the protection to light source; Also have another effect to be exactly can floor light, such as suitably can eliminate dazzle with off-white color lampshade, the lampshade higher with light transmittance can increase light efficiency etc.Can find to the spectrum analysis of light source, high energy blue light is substantially in 430-470nm wavelength period, and because the high wavelength of indigo plant that frequency is higher is shorter, refractive index is larger, and light is larger from the refraction angle medium directive air, is more easily totally reflected.Utilize this character, lampshade is re-started design, on the basis of profile size constancy, lampshade inner surface increases the lines of certain regular shape.As can be seen from partial enlarged drawing, each lines is all equivalent to one group of convex lens, and whole lampshade has 66 lines.As can be seen from index path, the material that light transmittance is high, refractive index is larger is selected can effectively to stop blue light to penetrate outside, wherein there is some blue light to penetrate with the angle less with lampshade face, because blue light is as easy as rolling off a log scattering in communication process, so direct irradiation does not enter the eyes of people, on eyesight without impact.
All generation reflected for the light from all directions, some even needs to reflect several times and could scatter in space with the form of dispersing, and this also makes the light of light fixture more even, and dazzle value significantly falls the end.
