Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ultraviolet stand for use in observing a fluorescent display paper surface on a desk surface through an appropriate filter.
[0002]
[Prior art]
A normal desk lamp is a visible light stand for illuminating a desk top surface with visible light. If the light source is replaced with an ultraviolet lamp, an ultraviolet stand is obtained. The main use of the UV stand is to irradiate and observe the fluorescent display paper surface on the desk surface with UV light.
The ultraviolet stand includes a lamp body including an ultraviolet lamp and a shade covering the upper hemisphere side of the ultraviolet lamp. Furthermore, it is desirable to attach a filter to the shade so as to protrude from the shade. The role of the filter is a clear vision filter for facilitating reading of the fluorescent display paper. Another role is to reduce the ultraviolet rays reflected back from the fluorescent display paper.
A person observes the fluorescent display paper surface from a position higher than the filter through the filter. That is a bird's eye view usage. The UV stand is a low-profile form suitable for a bird's-eye view usage. If the posture is placed at a low position, the ultraviolet lamp can be seen directly, but this is not preferable because it receives ultraviolet rays.

[Problems to be solved by the invention]
It is difficult to see if the UV lamp is lit when you prototype and examine the UV stand with the above structure. This is a problem that cannot be a visible light stand. The ultraviolet lamp is a so-called black light and includes some visible light, but it cannot be distinguished from outside light only by looking at the desk surface, and it is not clear whether the ultraviolet lamp is lit or not.
An object of the present invention is to enable easy confirmation of whether or not an ultraviolet lamp is lit. Accordingly, it is possible to confirm that the fluorescent display paper surface is in a standby state where observation is possible. It is also to prevent forgetting to turn off the ultraviolet lamp.
[0004]
[Means for Solving the Problems]
The present invention includes a lamp body including an ultraviolet lamp and a shade covering the upper hemisphere side of the ultraviolet lamp, and includes a filter attached to the shade so as to protrude from the shade, and the lamp body and the filter are mounted on a desk surface. It is premised on an ultraviolet stand that includes a stand that is held on top and that observes the fluorescent display paper surface on the desk top surface from a position higher than the filter through the filter.
In the present invention, a fluorescent display unit that receives and excites ultraviolet light in the shade and outputs visible light to the outside of the shade is disposed in a part of the shade. When the ultraviolet lamp is lit, the visible light is output, so it is possible to easily determine whether or not the lamp is lit even from a high position.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. The same terms are used for this description, and a part of the overlapping description is omitted as appropriate. The illustrated stand includes a lamp body 10 including an ultraviolet lamp 11 and a shade 12 that covers the upper hemisphere side of the ultraviolet lamp 11. A filter 20 attached to the shade 12 so as to protrude from the shade 12 is provided. A stand 30 for holding the lamp body 10 and the filter 20 on the desk surface is provided. This is an ultraviolet stand that observes the fluorescent display paper surface 100 on the desk top surface through a filter 20 from a position higher than the filter 20.
In the present invention, a fluorescent display unit 17 that receives and excites the ultraviolet ray L1 in the shade and outputs the visible light L5 to the outside of the shade is disposed on a part of the shade 12. As shown in FIGS. 2 and 3, the fluorescent display unit 17 includes a transparent window 18 formed in the shade 12 and a fluorescent display plate 19 disposed in that position. The illustrated alphabet (INVERTER) of the fluorescent display board 19 is drawn with fluorescent paint. The alphabet receives the ultraviolet ray L1 incident through the light transmission window 18 and emits light. The visible light L5 thereby reaches the eyes 101 outside the shade. It is a sign that it is lit.
I will supplement the details. The ultraviolet lamp 11 is, for example, a black light with an output of 6 W. The shade 12 includes a metallic reflector 13 disposed on the inner surface side thereof. Reference numeral 14 denotes a translucent window formed in a part of the reflecting plate 13 and transmits the ultraviolet ray L1. Reference numeral 15 denotes a component storage section provided on the back side of the shade 12 (right side in FIG. 1). The seed 12 and the component storage unit 15 are integrally formed of a synthetic resin material. The component storage unit 15 stores a circuit component (not shown) for turning on the ultraviolet lamp 11. A power cord 40 including a power plug 41 and a power switch 42 extends from the component storage unit 15. The filter 20 has a hinge structure, and its inclination is adjustable. The stand 30 includes a pair of lower leg portions 31 and an upper leg portion 35. The height of the entire stand 30 is adjusted stepwise by removing the connecting screw 33 that connects them and replacing the claw 34 at the lower end of the upper leg 35 with the optional receiving hole 32 on the lower leg 31 side. Reference numeral 39 denotes an adjustment screw provided at the upper end of the upper leg portion 35, which is loosened to adjust the inclination of the lamp body 10 with respect to the upper leg portion 35.
As shown in FIG. 1, most of the ultraviolet rays L2 from the ultraviolet lamp 11 are projected downward and enter the fluorescent display paper surface 100 on the desk surface. The fluorescent display paper surface 100 includes an information display unit 99 drawn with fluorescent paint. The information display unit 99 is excited when receiving the ultraviolet ray L2 to form a visible ray L6. The information display unit 99 is, for example, a barcode, and is information that cannot be read at all or almost not by ultraviolet rays L2. A part of the visible light L6 emitted from the information display unit 99 travels further upward through the filter 20 and enters the eye 101. The role of the filter 20 is to increase the contrast of the contour of the information display unit 99 and enable clear vision. Further, it is to limit the reflection component of the ultraviolet ray L2 from returning to the eye 101. Accordingly, the illustrated filter 20 is a clear vision / ultraviolet light reducing filter.

【The invention's effect】
The main feature of the present invention is that a fluorescent display unit that receives and excites ultraviolet rays in the shade and outputs visible light to the outside of the shade is disposed in a part of the shade. According to this, it is possible to easily confirm whether the ultraviolet lamp is lit or not, thereby easily confirming that it is in a standby state in which the fluorescent display paper surface can be observed. For this reason, it is also useful to prevent forgetting to turn off the ultraviolet lamp.
