Description

[Detailed description of the invention] [Industrial field of application] This invention is used in large buildings, such as lobbies of buildings, hotels, etc., or relatively large rooms, where multiple fluorescent lamps are installed upwardly. This invention relates to a light filter that covers the entire area below the light source of a large fluorescent lighting fixture installed therein.

[Prior art and its problems]

Conventionally, many covers have been attached to lighting fixtures that cover the light source of lighting fixtures that have multiple fluorescent lights installed inside them, but most of them are simply attached for the purpose of protecting the exposed fluorescent lights from external shocks, etc. Generally, a translucent or milky white thermoplastic resin thin plate is formed into a cover shape by pressing or the like to cover the lower part and allow light from the light source to pass through.

However, recently, covers with various shapes and other features to match the indoor atmosphere have become available on the market, but they do not take measures to soften the light itself from the light source, and the light that is unique to fluorescent lamps does not soften the light from the light source. The blinking sensation remained the same.

[Purpose of invention]

In view of the above, the present invention eliminates the blinking sensation characteristic of fluorescent light in fluorescent lighting fixtures, transmits soft light that does not irritate the eyes, creates a calm atmosphere, and is a decoration. The purpose of the present invention is to provide a light filter for lighting equipment that is highly versatile.

[Structure of the idea]

The structure of the present invention is to form a translucent sheet-like material on the entire surface of a large number of transparent glass tubes, and to form a recess on the upper edge for placing the large number of glass tubes in a direction parallel to the fluorescent lamp. Fix both ends of the mounting member to the lower side walls of the box-shaped body so that they are perpendicular to the fluorescent lamp and horizontal, and a large number of glass tubes are brought into close contact with the recessed part of the mounting member. It is placed on the entire surface of the open lower area.

[Example of idea]

The present invention focuses on the above-mentioned reasons and has been created as a light filter for fluorescent lamp lighting equipment, which softens the light of fluorescent lamps.

Next, embodiments of the present invention will be explained based on the drawings.

FIG. 1 is an explanatory diagram of an embodiment of the present invention, and the second
The figure is a sectional view of the main part.

The present invention is a light filter that covers the entire lower area of a box-like body 2 which is open at the bottom of a fluorescent lighting fixture 1 in which a plurality of fluorescent lamps A are installed, and includes a plurality of transparent glass tubes 3. A translucent sheet-like material 4 is formed by bringing the glass tubes 3 into close contact with the entire surface of the fluorescent lamp A, and a number of recesses 5 are formed on the upper end side for placing the plurality of glass tubes 3 in a direction parallel to the fluorescent lamp A. Both ends of a long book placement member 6 are fixed to both side walls of the lower side of the box-shaped body 2 so as to be perpendicular to the fluorescent lamp A and horizontal. A large number of glass tubes 3 are brought into close contact with each of the recesses 5 and placed over the entire open lower area of the box-shaped body 2.

That is, the present invention provides a large fluorescent lighting fixture 1 with a plurality of fluorescent lights A installed above, which is used in large buildings, such as lobbies of buildings, hotels, theaters, etc., or relatively large rooms. It is an optical filter that covers the entire area below the light source, and is made by pasting a translucent sheet material 4 closely on the entire surface of a large number of transparent glass tubes 3, or by coating or spraying a sol-like resin material. In some cases, a translucent sheet-like material 4 is formed, and the translucent sheet-like material 4 may be partially or regularly shaded to provide designs, patterns, etc. It is something.

Several elongated mounting members 6 have a large number of recesses 5 formed on the upper end side for mounting the large number of glass tubes 3 in a direction parallel to the fluorescent lamp A, but the outer diameter of the glass tubes 3 It is molded according to the conditions in which it is placed, and may be formed by processing a metal wire rod or by using a resin plate, etc., and the number of mounting members 6 is two or more. 1 and the weight of the glass tube 3 to be placed thereon. They are formed in the same shape.

Next, in order to place a large number of the glass tubes 3 in a direction parallel to the fluorescent lamps A, the respective mounting members 6 are arranged so that both ends thereof are perpendicular and horizontal to the fluorescent lamps A. After fixing each of them to the lower side walls of the box-shaped body 2 of the lighting fixture 1 by means such as screws or latches, the respective mounting members 6 are fixed.
The plurality of glass tubes 3 are inserted into each of the recesses 5.
The lamps are placed closely together and parallel to the fluorescent lamp A on the entire lower surface of the box-shaped body 2 of the lighting fixture 1 without any gaps.

In the embodiment shown in each drawing, a large number of glass tubes 3 are placed so that a portion thereof overlaps when viewed from the vertical direction, and the light from the fluorescent lamp A irradiated from above the lighting fixture 1 is The light is not directly irradiated downward, but is necessarily irradiated downward through the glass tube 3 on which the translucent sheet-like material 4 is formed on the entire surface.

[Effect of idea]

As mentioned above, the optical filter for the fluorescent lighting equipment of the present invention can be sufficiently manufactured using current technology and equipment, and since the sheet-like material is formed on the entire surface of the glass tube, even if the glass tube There is no risk of it scattering even if it is destroyed, and the characteristic twinkling light emitted by fluorescent lamps is unique due to the translucent sheet-like material with a transparent curved surface and the curved surface of the transparent glass tube. Due to its characteristics of refraction of light and diffuse reflection of part of the light on curved surfaces, it is able to transmit soft light without the sensation of blinking, and its design with many glass tubes lined up is elegant. It creates a high-class atmosphere, and maintenance of fluorescent lamps or glow lamps can be easily done by simply placing a glass tube on top of the tube. This is a design that is time-consuming, highly practical, and has remarkable effects.
