[Prior art]

  Lighting is a technology that illuminates something to make it bright or easy to see, and in a broad sense For the technology that uses light to fulfill various purposes or to make light useful for human life Nonetheless, the technology of light sources and lighting that uses them has developed, and In lighting fixtures used for the purpose of protecting light sources such as globes or for protecting Also, change the orientation of the light source to soften the high brightness, protect the light source mechanically, etc. At the same time, it has a decorative effect such as supporting the light source or acting as an object in the room. Functions to fulfill are also required.

[0003]

[Problems to be solved by the device]

  Lighting fixtures perform various functions, such as specular reflection, diffuse reflection, specular transmission, diffuse transmission, It is designed in consideration of refraction, etc., and its instrument efficiency is to achieve various functions. Side by side, it is also a major factor in determining the performance of lighting equipment, The effect of softening is emphasized and it corresponds to indirect lighting from the globe and diversification of lifestyle Recently, however, I'm also interested in multifunctional lighting, including direct lighting and indirect lighting with a single fixture. It is sent. For example, because it is dark only with indirect lighting, so-called semi-direct lighting, or Attention has been focused on a composite type that combines a direct lighting fluorescent lamp and an indirect lighting incandescent lamp. And for the illumination by the umbrella, translucent materials such as milky glass, plastic, paper, etc. The basin made of a base material is generally distinguished from the reflective visor, and its function is similar to that of the reflective visor. In addition to increasing the utilization rate, it also has the effect of light diffusion. However, A splendid atmosphere is desired depending on the lighting facility, and appropriate decoration is often required. In addition, in a living room, dining room, store, etc., where such an atmosphere is emphasized A clear method is desired.

[0004]   In addition, the illumination by the globe in the conventional illumination method is usually 15 to 20% for opalescent glass. However, if the light source is completely wrapped, the light reflected on the inner surface will not be reflected. The entire luminous flux that leaves the globe after running around the inside and repeating reflections to raise the illuminance on the inner surface The total luminous flux directly from the light source is about the same, and the light emitted from the light source can be effectively used. Since it encloses the light bulb, it has the advantage that dust and dirt do not adhere to the inner surface or light source. To reduce the light emitted from the It is being conducted to consider a proper area or the shape of the groove.   Furthermore, in the lampshade, dust and dirt tend to adhere to the side walls and bulbs of the lampshade. In this respect, the globe encloses the bulb, so dust etc. may adhere to it. It can be said that the irradiation efficiency of the light source is less likely to decrease, but For a bulk made of a semi-transparent material such as tic, dust or dust due to the generation of static electricity However, there is a problem in that it is easily attached and deposited on the substrate.

[0005]

[Means for Solving the Problems]

  The present inventor examined the above problems, and in the present invention, the light emitted directly from the light source is It has a light transmitting property that exhibits a softening effect, and has a decorative property for the decorative effect. However, as a whole, it has a transmittance of about 20% or less, preferably 15% or less. However, the brightness of the light source is reduced to avoid glare and to soften the light, so that the illuminance on the inner surface is too large at each point. In order to produce the so-called Andon effect, which is almost uniform so as not to make a difference, the conventional milk-colored glass In addition to semi-transparent materials such as plastics and paper, shade base material made of non-woven fabric, or Is a non-woven fabric containing conductive fillers such as metal powder, metal flakes, and metal short fibers. To prevent a decrease in illuminance due to adhesion of dust, etc. A bead-shaped transparent lens spherical element is layered on one of the outer side walls and reflected by a refraction means. The two functions of the means form an integrated structure to give the lampshade a decorative effect. The present invention has been achieved as a result of diligent studies, focusing on the problem of

[0006]   The present invention relates to a lighting lamp shade having an appropriate shape, wherein the shade base is Form a decorative part with a beaded transparent lens spherical element layered on the inner or outer side wall surface of the Or a transparent lens element on at least a part of the shade substrate Layered structure, and the shade substrate is a non-woven fiber material or short metal fibers An internally illuminated lampshade made of a non-woven fabric constituent material containing a conductive filler such as The purpose is to provide. The other purpose is semi-transparent diffusion with brilliant elegance In addition, it is possible to use an internally lit lampshade device that can continuously exert the Andon effect with a simple and low cost.
