Abstract

(57) [Abstract] [Purpose] To provide a new lamp cover that can obtain more sufficient diffusion of light, widen the irradiation angle, improve the visibility from the side direction, and simplify the configuration. The purpose is to provide. [Structure] A semi-spherical light-transmitting wall body 2 is formed by combining synthetic resin transparent spherical particles 1 while maintaining the particle shape, and the outdoor illumination lamp body is formed at the opening edge of the light-transmitting wall body 2. The mounting edge 4 to the 3 is provided together at the time of the above molding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lamp cover such as a flashlight, an outdoor lighting lamp, a bicycle headlight, a signal lamp, a Christmas tree decoration lamp, and an interior decoration lamp.

[0002]

[Prior art]

 Conventionally, there is known a lamp cover in which a myriad of hemispherical or pyramidal projections are provided on the inner surface to diffuse light from the lamp.

[0003]

[Problems to be solved by the device]

 The lamp cover described in the above-mentioned conventional technique cannot always obtain sufficient diffusion, has a narrow irradiation angle, and is inferior in visibility from the side direction. In addition, it was not easy to provide a myriad of hemispherical or pyramidal protrusions on the inner surface.

The present invention provides a novel lamp cover that can obtain more sufficient diffusion of light, widen the irradiation angle, enhance the visibility from the side direction, and facilitate the configuration. The purpose is to do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the lamp cover according to the present invention has a light-transmitting wall surface in which granular transparent bodies are combined while maintaining the granular shape, and the combination of the granular transparent bodies is transparent. This is done through the wall member.

[0006]

【Example】

 In the first embodiment shown in FIG. 1, a synthetic resin transparent spherical particle 1 is formed by bonding while maintaining the particle shape to form a hemispherical light-transmitting wall body 2, and an opening of the light-transmitting wall body 2 is formed. The mounting edge 4 for the outdoor lighting body 3 is provided at the edge together with the above molding.

In the second embodiment shown in FIG. 2, a transparent wall member 7 having a mounting edge 6 to the flashlight body 5 is formed by transparent synthetic resin molding, and the side wall of the side wall of the transparent wall member 7 is formed. A transparent wall surface portion 9 is provided on the inner peripheral surface of which a plurality of transparent synthetic resin transparent particles 8 having a spherical shape are adhesively bonded while maintaining the particle shape.

In a third embodiment shown in FIG. 3, a transparent wall member 12 having a mounting edge 11 to the illuminating lamp body 10 is formed by transparent synthetic resin molding, and a side peripheral wall of the transparent wall member 12 is formed. A transparent wall surface portion 14 is provided on the inner peripheral surface, in which the distorted spherical transparent synthetic resin particles 13 are adhesively bonded while maintaining the particle shape.

In a fourth embodiment shown in FIG. 4, a myriad of synthetic resin transparent spherical particles 15 are bonded while maintaining the particle shape to form a hollow spherical Christmas decoration object 16 composed of a light-transmitting wall surface. Then, a mounting hole 17 is opened in this concrete body 16, and a miniature lamp 18 is inserted into the mounting hole 17 and stopped.

The present invention can be implemented as follows. A granular transparent body (grain) is colored and transparent. The transparent wall body is colored and transparent. The shape of the grain is polygonal, short tubular, or any other shape. The particles are made of glass. Let the lamp be a neon discharge lamp.

[0011]

[Action]

 In the present invention, the granular transparent body (granular body) diffuses the light of the lamps 16, 19, 20, 21 of the main body of the illuminating lamp, the main body of the flashlight, etc. more diffusely than the hemispherical or pyramidal projections in the above-mentioned conventional example, The amount of light emitted outward is increased by diffuse reflection and the lens effect, which widens the irradiation angle and improves the visibility from the side.

[0012]

[Effect of device]

 The lamp cover according to the present invention can obtain more sufficient diffusion of the light of the illumination lamp, the flashlight, and the decorative concrete object to which the lamp cover is attached, widen the irradiation angle, and improve the visibility from the side direction. In addition, since it can be formed by bonding transparent particles, the structure is easier than that of the conventional example in which the above-mentioned projection is integrally formed or cut.
