Description
【発明の詳細な説明】 〔発明の技術分野〕 本発明はけい光ランプスタンドの改良に関する。[Detailed description of the invention] [Technical field of invention] The present invention relates to improvements in fluorescent lamp stands.
従来のけい光ランプスタンドは直管形ランプ用でも環形
ランプ用でも皆支柱に支持されたセード内に蛍光ランプ
を収容してあり、前方から見るとランプが露出していた
。Conventional fluorescent lamp stands, whether for straight tube lamps or annular lamps, all house the fluorescent lamp in a shade supported by a column, and the lamp is exposed when viewed from the front.
上記従来のけい光ランプは次の欠点がある。 The above conventional fluorescent lamp has the following drawbacks.
（１）作業中、視野内にランプが入るとグレヤを生じる
。(1) Glare occurs when a lamp enters the field of view during work.
（２）照射距離が短いため直射光が被照射物から反射し
てグレヤを生じる。(2) Since the irradiation distance is short, the direct light is reflected from the irradiated object, causing glare.
（３）けい光ランプを交流で点灯する場合、けい、光ラ
ンプの両嬬の電極が半サイクル毎に交互に極性を異にし
放電作用を成してけい光ランプを点灯するものであるが

光度９高い陰極グローと交互に現れるため、これがちら
つきとして眼に感じる、特に、けい光ランプスタンドは
照射距離が短い庭め、そのちらつきは著しく不快に感じ
る。(3) When lighting a fluorescent lamp with alternating current, the electrodes of both the fluorescent lamp and the fluorescent lamp alternately change polarity every half cycle to create a discharge action and light the fluorescent lamp. Near the ends of both tubes, the anode glow, which has a lower luminous intensity, and the cathode glow, which has a luminous intensity 9 higher, appear alternately on the cathode side, and this can be perceived as flickering.Especially when using a fluorescent lamp stand in a garden where the irradiation distance is short, The flicker feels extremely unpleasant.
（４）被照射面を斜めに照射するため一様な照度になら
ない。(4) Since the irradiated surface is irradiated obliquely, the illuminance is not uniform.
本発明はグレヤやフリッカがなくしかも照度分布が均一
なけい光ランプスタンドを提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a fluorescent lamp stand that is free from glare and flicker and has a uniform illuminance distribution.
けい光ランプの管端部を含む全長にわたりその前面を内

て、グレヤやフリッカをなくしたものである。The front surface of the fluorescent lamp is covered over its entire length including the end of the tube with a light-reflecting light-shielding plate, and a light guide is provided on the side edge of this light-shielding plate. It is reflected on the inner surface and radiated forward from the light guide part to increase the luminous flux to the front e, thereby making the illuminance distribution uniform.Moreover, the lamp, especially the end of the tube, is not directly visible, eliminating glare and flicker. It is something.

) is dimensioned so that the gap with the inner surface of the lamp (5) is as narrow as possible; The inner surface of the light-shielding plate (6) is made light-reflective, and the front surface is painted in a decorative manner.Then, it can be mounted inside the shade (3) in an appropriate manner.For example, as shown in Figure 5. A grip plate is provided on the inner surface of the light shielding plate (6) as shown in the figure, and the lamp (5
) may be rotatably pivoted to the tube end 6υ of ), or may be elastically engaged to sockets (4), (4), although not shown.
つぎに、本実施例スタンドの作用を第６図によって説明

ランプ（５）に反射し、さらに他の部分に放射される。Next, the operation of the stand of this embodiment will be explained with reference to FIG. Of the light emitted from the fluorescent lamp (5), the light (R1), 12) incident on the top plate of the shade (3) is reflected and emitted forward from the light guide section 16. Also, the light (R3) that enters the edge of the light shielding plate (6) from the lamp (5) is reflected and enters the shade (3), where it is further reflected and radiated forward from the light guide parts. . In addition, the lamp (
The light incident on the central part of the light shielding plate (6) from 5) is reflected back to the lamp (5), and then radiated to other parts.

も目には見えず、フリッカを生じることがない。Therefore, by reducing the light loss on the inner surface of the shade (3) and the light shielding plate (6), it is possible to illuminate the area uniformly without reducing the efficiency of the light fixture. Moreover, the light from the lamp (5) does not directly hit your eyes or the surface of the paper at hand, reducing glare and fatigue.In particular, both ends 6υ of the light-shielding plate (6) (611 are the lamps (5) Since it completely covers the tube ends (51), 6+) of the filament, even if the brightness of the filament part flickers, it will not be visible and no flicker will occur.

（６）中火に形成された光導出孔である。Next, an example of an annular fluorescent lamp stand to which the present invention is applied is shown in FIGS. 7 and 8. In the figure, (2) is the same pillar as above, (3) is a circular shade supported by this pillar (2), (4) is a socket provided in this shade (3), and (5) is a shade ( 3) The annular fluorescent lamp (G) installed in the lamp (5) is connected to the socket (G) with the base of this lamp (5).

The lamp tube end 61) is provided on a part of the H nib 0 plate (6).
The end completely covers the lamp, and the outer part corresponds to the middle part of the lamp.
A light guide hole formed in the notch on the edge 111, σill, is a light guide hole formed in the middle of the light shielding plate (6).
このスタンドも前述の直管形ランプスタンドと同様照度
分布が均一でまぶしくなく、しかも管端部（５１）の光
が直接見えないのでフリッカによる疲労もない。Like the straight tube type lamp stand described above, this stand also has a uniform illuminance distribution and is not dazzling, and since the light from the tube end (51) is not directly visible, there is no fatigue caused by flicker.
なお、前述の各実施例において、光導出部（６２は遮光

の構成材料は金属に限らない。In each of the above embodiments, the light guide portion (62) was formed by cutting out a part of the light shielding plate (6), but in the present invention, a light transmitting plate may be provided. It is sufficient that the light transmits through the light well.Furthermore, in the annular fluorescent lamp stand, the light guide hole of the light shielding plate (6) may not be provided.The constituent material of the light shielding plate is not limited to metal.

全に遮光されているのでフリッカによるｉ労もない。The fluorescent lamp stand of the present invention is housed in a shade and covers the entire length of the fluorescent lamp, including the tube end facing the light emitting opening, with a light-shielding plate having internal light reflection properties, and also has a light-shielding plate that covers the middle part of the lamp. Since the light guide part is provided on the side edge, a large amount of light is irradiated to areas that are far away from the stand, so the illuminance distribution on the illuminated surface is uniform and does not directly hit the eyes or paper surface, so there is no glare. Since the end of the lamp tube is completely shielded from light, there is no need to worry about flickering.
