[Industrial applications]

 The present invention relates to a lighting fixture for viewing and staging, which has a structure of irradiating a subject made of a special phosphor with ultraviolet rays of a certain wavelength to cause fluorescence emission.

[0002]

[Prior Art]

 Conventionally, as a lighting method aiming at a production effect on a disco or a stage for entertainment, for example, a mirror ball, which has many mirror pieces attached to the surface of a sphere, is rotated and irradiated with light. Various types are used, such as those that utilize the reflected light that is generated as a result, and those that aim at a staging effect by blinking and moving the light while irradiating the laser beam with a constant movement.

In recent years, an illumination light source called a black light that generates ultraviolet rays having a special wavelength has been developed. Such a black light is an illumination light source that emits only safe ultraviolet rays with a wavelength of 365 nm as the center. Moreover, it is excellent in fluorescent light emission, and when such a black light is used to irradiate a specific color material with ultraviolet rays, it is reflected as a special phosphor and various hues and patterns can be expressed.

Recently, as a coloring material that is irradiated with ultraviolet rays by such a black light, it is not recognized by the human eye as white when irradiated with ordinary illumination, but it is irradiated with light in a wavelength band of around 365 nm. In addition, a special phosphor is used that can distinguish visible coloring materials as visible light and produces vivid colors.

[0005]

[Problems to be solved by the device]

 However, for example, the production lighting technology using a laser beam has complicated health problems such as complicated facilities, high cost, and bad human vision.

On the other hand, regarding a new color illumination technology that uses a combination of a black light and a special phosphor, the fixed face piece is irradiated with ultraviolet light by a black light on a picture or a character drawn with the special phosphor. Because it is used for various purposes, the fluorescent plate provided with the special phosphor only enjoys the enjoyment of changing regularly, and it is not possible to generate various reflective fluorescent colors that change from moment to moment. It was easy for the viewer to get tired of because there was only one pattern of changes.

An object of the present invention is to provide a lighting fixture that solves the above problems.

[0008]

[Means for Solving the Problems]

 According to the present invention, a subject made of a rotatable special phosphor is arranged in the approximate center of the base case, and a wavelength of around 365 nm is placed at a position separated from the subject by a certain distance on the outer periphery of the subject. It is intended to provide a lighting fixture having a characteristic that an ultraviolet ray irradiator for irradiating the ultraviolet ray is arranged.

[0009]

[Action]

 The luminaire of the present invention is installed on the ceiling or the side wall, and while rotating the subject with an actuator such as a motor, the illuminator that surrounds the subject at a certain distance is operated, while the ultraviolet irradiator emits light. Ultraviolet light with a wavelength of around 365 nm is emitted to hit the subject and emit light.

Since the subject is coated with a special phosphor that emits light when irradiated with ultraviolet rays of the above wavelength, the subject emits fluorescent light as the shape of the rotating subject changes, giving rise to various fantastic and vivid images. Produces light.

The base case 1 has several mounting holes 2 on its upper surface. It is provided and can be attached to the ceiling or the side wall. That is, as shown in FIG. 3, the ceiling board 10 is penetrated through the mounting holes 2 of the base case 1 into the board mounting frame 11 made of channel steel or the like provided inside the ceiling board 10 of the ceiling. The connecting case 12 is inserted to fix the base case 1 to the ceiling.

The base case 1 is formed in a rectangular shape, and four UV irradiators 3 for irradiating ultraviolet rays are mounted as tubular glass bulbs of a certain length near each side inside the base case 1. It irradiates ultraviolet rays with a wavelength of around 365 nm. Further, as shown in FIG. 3, a motor 4 is arranged inside the center of the base case 1, and a support rod 5 connected to the motor 4 is rotated by an output of the motor 4, and the support rod 5 is rotated. At the lower end of 5, a star-shaped subject 6 as shown in FIG.

The surface of the subject 6 is coated with a special fluorescent substance as a coloring material, and such coloring material is not recognized by human eyes as white under normal illumination. Although it is a color, it emits fluorescent light when irradiated with ultraviolet rays in the wavelength band around 365 nm, and the colors that emit fluorescent light are fantastic and vivid.

Moreover, the color of the special phosphor can be easily changed by toning several colors, and the material of the phosphor can be various materials such as paint, resin plate, fiber and film. Various shapes are possible.

In the present embodiment, the special phosphor is applied on the surface of the star-shaped subject 6 with different hues and shapes on each surface, and several different colors are toned and the atmosphere of the place to be used is adjusted. Although the coloring material is suitable for the surrounding atmosphere, it is also possible to attach a film-shaped special phosphor to the surface of the subject, or to form the subject with a plate-shaped phosphor.

The subject 6 is connected to the support rod 5, but the shape thereof is not particularly limited, and the structure is such that it can be easily detached from the support rod 5, and the illumination device remains the same. We are trying to make it possible to produce using various subjects. The ultraviolet irradiator 3 for irradiating ultraviolet rays is electrically connected to a box-type lighting device 7 having a power supply, a stabilizer, and the like provided on the inner surface of the base case 1, and is electrically connected to the box-type lighting device 7. 7 is configured to irradiate light with a wavelength of around 365 nm. The ultraviolet light emitted by the illuminating device 7 does not include harmful ultraviolet rays contained in light of 200 to 315 nm, and is a light source that extracts only safe ultraviolet rays. It is possible to produce various excellent color light patterns by changing the fluorescent light emission effect by visual change. The base case 1 can be fixed to not only the ceiling but also the side wall or the floor surface, or placed on the floor surface, and various objects can be produced by rotating the object 6.

Reference numeral 8 denotes an apron portion which is vertically provided at a corner of the base case with a certain spread. A reflection plate 9 is provided on an inner wall of the apron portion, and an ultraviolet ray provided in front of the reflection plate 9 is provided. The ultraviolet light generated from the irradiator 3 is condensed and applied to the subject 6 to emit light.
