JPH06338201A - Illuminator - Google Patents

Abstract

PURPOSE:To provide an illuminator which produces life space with an illumination light having natural fluctuation through liquid by covering a light source installed at a ceiling, and causing movement in the liquid accommodated inside the cover. CONSTITUTION:An illumination cover 2 by an acylic board or the like is fixed to a structural member such as the beam 3 or the like at a ceiling face by means of a bolt and a nut 4, and also a light source 1 such as a fluorescent lamp is attached to the ceiling face 8, and a transparent inner cover 6 is provided between the light source 1 and the transparent cover 2, and liquid 7 such as water or the like is accommodated in the space between both covers 2 and 6. Indoor space is produced with an illumination light having natural fluctuation through this liquid 7 by lighting the light source 1 and also, vibrating it with the vibration plate 5b inside the liquid by means of a vibrator 5a thereby generating fluctuation in the liquid 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for houses, shops and the like. More specifically, the present invention relates to a lighting device in which illumination light changes with time and creates a living space.

[0002]

2. Description of the Related Art In recent years, various lighting devices in which illumination light changes with time have been devised or put into practical use for the purpose of producing a living space. There are various methods of changing the illumination light with time, but in order to create a natural "fluctuation" that gives comfort to the human sense, a lighting device that uses water movement such as water currents and ripples on the water surface is available.

Japanese Unexamined Patent Publication No. 3-93102, “Lighting fixture with flowing water”
This is presented in Japanese Laid-Open Publication "Lighting Equipment Utilizing Ripples on Water Surface".

However, what is presented in any of the above techniques is an illuminating device which is installed mainly on the floor and illuminates the upper part. Since such a lighting device occupies a considerable floor area, and the irradiation light from the lower part to the upper part is not suitable for daily use, it is not suitable for installation in a general house or a small-scale store. The present invention has been made to solve the above problems, and utilizes the movement of a liquid to produce natural "fluctuation" in illumination light to produce an indoor space, and an illumination device that can be installed on the ceiling. The purpose is to provide.

[0004]

In order to achieve the above object, the "illuminating device" of the present invention has a light source and a light-transmitting cover that covers the light source from below, and a liquid is contained in the cover. Is housed,
It is characterized by comprising a vibrating device or a stirring device or a circulation device for causing the liquid to move.

Here, the type of the light source is not particularly limited, and any of those used in general houses and shops such as incandescent lamps and fluorescent lamps can be selected.

The cover that covers the light source needs to have a light-transmitting property such that the light emitted through the light source can provide sufficient indoor illuminance, but it need not necessarily be colorless and transparent, and may be colored. . The shape of the cover may be a relatively planar shape or a three-dimensional shape, but it does not deform due to the weight of the liquid contained therein, and the cover does not move even when the liquid moves. It is constructed so that it will not leak out. Various shapes may be selected within the range satisfying this condition, and a surface design may be added. Further, it is preferable to select, for example, acrylic as the material of the cover in consideration of long-term durability.

In the lighting device of the present invention, since the liquid is contained in the cover and the weight of the entire cover increases,
It is desirable to fix the load so that the structural member of the ceiling directly bears this load. Here, the structural member of the ceiling means a beam or a beam. As a fixing method, bolts and nuts are best fixed in consideration of sufficient strength, workability, and maintainability, but other methods such as one-sided bolt fixing, rivet fixing, and welding between metal materials are also available. Can also be mentioned.

As the liquid used in this apparatus, water is the most practical from the economical point of view, safety and hygiene, etc., but a coloring effect may be added to enhance the effect.

A vibrating device or an agitator or a circulation device is used to cause the liquid contained in the cover to move. Here, the vibrating device is a device that mechanically vibrates the vibrating plate immersed in the liquid to cause the liquid to move.
The stirrer is a device that rotates a rotary blade immersed in the liquid to cause the liquid to move. The circulation device is a device that uses a pipe and a pump to create a flow in the liquid in the cover to cause movement. Further, these devices may be used together.

In view of the structure, when the liquid is splashed on the light source or the electric system or there is a concern that the vapor may adversely affect, it is desirable to provide an inner cover to protect the light source or the electrical system.

[0011]

[Function] Since the light emitted downward from the light source installed on the ceiling is transmitted through the liquid moving in the cover and is emitted to the room, the indoor space is produced by the illumination light with a natural "fluctuation". be able to.

[0015]

[Effect] As described above, according to the present invention, it is possible to install on the ceiling an illuminating device that produces an indoor space with illuminating light with "fluctuation" that is transmitted through a liquid moving in the cover. . That is, since the irradiation light from the upper side to the lower side, which is suitable for daily use, can be obtained without occupying the floor area, it can be suitably installed in a general house or a small-scale store.
