Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative illuminating device capable of displaying various patterns by irradiating a fluorescent paint coating portion drawn with fluorescent paint with ultraviolet rays and emitting light from the fluorescent paint coating portion. The present invention relates to a decorative lighting device capable of displaying two or more types of light emission patterns.

[0002]

2. Description of the Related Art In recent years, since a fantastic atmosphere can be created and an extremely strong impression is given to the viewer, a picture is painted on the surface of a wall or the like with fluorescent paint, and the picture drawn with this fluorescent paint is irradiated with ultraviolet rays. Decorative lighting devices that emit light by lighting have come to be used.

Conventionally, such a decorative lighting device is provided with a fluorescent paint application section on the surface of the substrate facing the viewer, and an ultraviolet lamp is provided in front of the fluorescent paint application section.
A predetermined light emission pattern is emitted by irradiating the fluorescent paint application portion with an ultraviolet lamp.

[0004]

However, the above-described conventional decorative lighting device can display only one type of light emission pattern, and the change in the decorative content is poor.

An object of the present invention is to solve the above problems and to provide a decorative lighting device capable of displaying two kinds of light emission patterns.

[0006]

Means for Solving the Problems The inventors of the present invention have made extensive studies to achieve the above object and found that a transparent acrylic plate significantly attenuates ultraviolet rays. That is, it was found that the transparent acrylic plate is transparent to visible light but opaque to ultraviolet light. Then, the present inventors have further studied based on the above findings and completed the present invention.

That is, the decorative illumination device according to the first aspect of the present invention includes a substrate that transmits visible light but does not transmit ultraviolet light, and a front side fluorescent coating material coating portion provided on the front side surface of the substrate.
Characterized by having a back side fluorescent paint coating section provided on the back side of the substrate, a front side ultraviolet lamp for irradiating the front side fluorescent paint coating section with ultraviolet rays, and a back side ultraviolet lamp for irradiating the back side fluorescent paint coating section with ultraviolet rays It is configured.

In the decorative lighting device according to the second aspect of the present invention, a rotatably provided substrate that transmits visible light but does not transmit ultraviolet light, and a first fluorescent paint coating section provided on one surface of the substrate. And a second fluorescent paint applying section provided on the other surface of the substrate, and an ultraviolet lamp capable of irradiating at least one of the first fluorescent paint applying section and the second fluorescent paint applying section with ultraviolet light. It is configured.

The substrate transmits visible light but does not transmit ultraviolet light. Examples of materials having such characteristics include organic materials such as acrylic plates and epoxy plates,
There are inorganic materials such as glass plates.

The fluorescent paint application section is drawn with fluorescent paint, and as the fluorescent paint, Green, Yellow Gre
een (yellow green), Yellow (yellow), Orange (orange), Red (red),
DeepRed, Pink, Violet (purple), DeepBlu
e (dark blue), Blue (blue), BlueGreen (blue green) and White
There is (white).

The ultraviolet lamp is only required to be able to emit light by irradiating the light emitting portion with ultraviolet rays, and for example, a mercury lamp type ultraviolet lamp or a fluorescent lamp type ultraviolet lamp can be used. Further, the irradiation of the ultraviolet rays may be performed with its optical axis perpendicular to the light emitting portion or obliquely.

[0012]

In the decorative lighting device according to the first aspect of the present invention, the front ultraviolet lamp can irradiate the front fluorescent paint coating portion with ultraviolet rays.
Since the back side fluorescent paint application part cannot be irradiated with ultraviolet rays because of being blocked by the substrate, the front side ultraviolet lamp makes only the front side fluorescent paint application part emit light. Similarly, the back UV lamp causes only the back fluorescent paint application section to emit light. Therefore, by operating the irradiation of both the ultraviolet lamps, either one or both of the fluorescent paint application parts can be made to emit light.

In the decorative lighting device according to the second aspect of the present invention, by rotating the substrate, the fluorescent paint coating portion facing the ultraviolet lamp can be changed and the fluorescent paint coating portion facing the ultraviolet lamp can be irradiated with ultraviolet rays. Do not irradiate ultraviolet rays on the fluorescent paint application section on the opposite side. Therefore,
Either the first fluorescent paint applying section or the second fluorescent paint applying section can emit light.

Does not emit light.

Next, when the shutter 51 is opened, as shown in FIG.
After reaching 21 and irradiating the front side fluorescent paint applying section 31 to emit visible light b, the back side fluorescent paint applying section 32 cannot be irradiated because the ultraviolet ray a cannot pass through the inside of the substrate 20 and the back side fluorescent paint applying section 32. Does not emit light. Therefore, only the front fluorescent paint application section 31 can be viewed.

Further, when the shutter 51 is closed and the shutter 52 is opened, the ultraviolet rays c of the ultraviolet lamp 42 reach the back side surface 22 of the substrate 20 and irradiate the back side fluorescent paint application section 32, as shown in FIG. The visible light d is emitted, and the visible light d passes through the substrate 20 and travels from the front surface 21 toward the viewer. However, since the ultraviolet rays c cannot pass through the substrate 20, the front side fluorescent paint applying section 31 cannot be irradiated, and the front side fluorescent paint applying section 31 does not emit light. Therefore, the back side fluorescent paint application section 32
Can only be seen.

Then, as shown in FIG. 6, the front fluorescent paint coating section 61 is irradiated with the ultraviolet rays e of the ultraviolet lamp 70 and emits visible rays f. However, since the ultraviolet rays e cannot pass through the substrate 50, the back side fluorescent paint coating part
It is not possible to irradiate 62, and the backside fluorescent paint application section 62 does not emit light.

Next, when the substrate 50 is turned upside down and the back side fluorescent paint applying section 62 is rotated in a direction inclined to the viewer side (clockwise direction in the figure), the back side fluorescent paint applying section 62 is applied as shown in FIG. Part 62
