Abstract

The utility model relates to a lamp shade, which mainly comprises a cover shell and a cone body, wherein, the cone body consists of a plurality of inner surface and outer surface square beams; the square beams form an interlaced reticulated pattern; and the width, the rake and the angularity of the each inner surface and outer surface square beam are different, so as to form the meniscus lens with different angles by combining in different angles. The utility model can evenly scatter lights in the needed range, so as to reduce glare and the equality of light. By broadening the arranged position of a lamp, the utility model reaches the aim of saving energy, reducing the number of lamp and at the same time protecting eyes of a reader under the even light.

Description

Lampshade

Technical field

The utility model relates to a kind of lampshade, and is particularly a kind of applicable to the lampshade on the ceiling type light fixture.The principle of utilization concave-convex lens reduces the generation of dazzle with the range widens of light scattering, and has improved the uniformity of light.

Background technology

Because the rise in building, the utilization of lamp affixed to the ceiling is more and more many, general lamp affixed to the ceiling all is that light fixture is fixed on the ceiling (roof), in order to prevent that the light fixture direct irradiation from producing dazzle, usually all can be at the outer mask upper lamp shade of light source (fluorescent tube or bulb), thus, the brightness of light is lowered, therefore can set about from two for the usefulness of strengthening lamp affixed to the ceiling: the first adds the usefulness of intense light source (fluorescent tube); Its two be the improvement lampshade effect.The utility model then is to set about from the improvement lampshade.

Current lamp affixed to the ceiling (or other forms of lamp), in order to reduce dazzle, majority is that lampshade is made frosted glass, opal glass or polyester, the product that has is also made the equidistant reticulate pattern of single face.These designs only can reduce the generation of dazzle, but fail to consider to improve the uniformity of light.

In order to solve the not good problem of the light uniformity, all be with shown in Figure 1 at present, the position between light fixture is dwindled as far as possible, make light project the not enough place of outer light source, increase brightness because a plurality of lamp light source is overlapping, cause naturally to waste energy and increase cost.

Technology contents

Main purpose of the present utility model is to provide a kind of lampshade, and the reflection function after utilization concave-convex lens principle improves light source and irradiates is so that scatter to light in the maximum optimal scope.

Secondary objective of the present utility model is to provide a kind of lampshade, to on the inside and outside surface of the case of lampshade rib be set respectively, the rib on this two sides forms with longitudinal and transverse being staggered, make the light source of light fixture can see through the bullet that this rib constitutes, form concave-convex lens and construct scattering light source, enlarge irradiated area.

Another secondary objective of the present utility model is to provide a kind of lampshade, three component parts at each rib on inside and outside surface: width, gradient, angularity all have nothing in common with each other, therefore the cone shape that is constituted is different, also just forms each different meniscus configuration.Thereby the utility model also utilizes reticulate pattern to reduce the generation of dazzle, utilizes lens principle to increase spread again and reaches the purpose that enlarges illuminance.

Lampshade of the present utility model can be used on the various light fixtures, and the structure of its light fixture and light structures all belong to known, so the utility model only is design agents with the lampshade, to preferred embodiment of the present utility model, further specifies as follows below in conjunction with accompanying drawing.

The specific embodiment

Referring to Fig. 2,3,4, lampshade described in the utility model has case 1, on case 1 outer surface 3, be provided with rib 31 outside many, inner surface 4 is provided with many interior ribs 41, angularity, width and gradient by this rib 31,41 have nothing in common with each other, needs when this is not both according to design are calculated by computer, and mould is made in etching then, and forms behind injection molding.

As shown in Figure 5, can constitute the bullet 2 of lens effect via the rib 31,41 of different angles, shape.When light is radiated on the bullet 2 of case 1, light can be scattered out in optimal mode, reach the purpose that illumination zone increases.

As shown in Figure 6, for the utility model being applied to the schematic diagram on the general lamp affixed to the ceiling, by this view as can be known, case 1 of the present utility model directly is sleeved on the outside of light fixture 5.Identical on the profile with original product, do not have the situation generation that new lampshade can't be applicable to old light fixture, be to have used case 1 of the present utility model can reach the purpose that light source fully evenly scatters again on the contrary, and increase range of exposures.

Be illustrated in figure 7 as another kind of enforcement situation, the utility model device also can be used on thin light fixture 5.

As shown in Figure 8, utility model is because the light source nephelometric turbidity unit is wide, so available relatively broader mode is arranged, and can reduce the use of light fixture, promptly saves cost, but energy savings again.

Case 1 of the present utility model and cooperate light fitting shape to make various difformities, present embodiment only is the embodiment target with square, and unrestricted lampshade of the present utility model must only be square.

Claims

1, a kind of lampshade, it mainly includes case, bullet, it is characterized in that: be respectively equipped with some ribs on the inside and outside surface of this case and constitute bullet, the rib on aforementioned inside and outside surface forms for being staggered.

2, lampshade according to claim 1 is characterized in that: the width of this each rib, gradient, angularity all have nothing in common with each other.

3, lampshade according to claim 1 is characterized in that: this case can be four angulars.
