特開2004−131264号公報(第1頁、図4)Japanese Unexamined Patent Publication No. 2004-131264 (first page, FIG. 4) 特開平7−158293号公報(第1頁、図1)JP-A-7-158293 (first page, FIG. 1)

上記のような従来の照明装置においては、特許文献1の技術では、光ムラをある程度解消するために、光源から間隔をあけて透光性の乳白色樹脂板等の照明カバーが配置されるため、光源と照明カバーの間に一定の寸法を必要とし、このため天井深さが大きくなり、エレベータレイアウトにおいて建築側の省スペース化が妨げられ、ないしはかご室の内部空間が抑えられるという課題があった。また、特許文献2の技術では天井パネルの室内側表面に設けられた光を導光、屈折、拡散させる効果を有する面体の部分は薄型であるというものの、端縁部に点検口を有する照明ボックスが天井から下方向にせり出しているため部分的に薄型化が達成されておらず、また、点検口を有しているため、意匠上の制約が発生するという課題があった。   In the conventional illumination device as described above, in the technique of Patent Document 1, an illumination cover such as a translucent milky white resin plate is disposed at a distance from the light source in order to eliminate light unevenness to some extent, There is a problem that a certain dimension is required between the light source and the lighting cover, which increases the ceiling depth, hinders the space saving on the side of the building in the elevator layout, or suppresses the interior space of the car room. . In addition, in the technique of Patent Document 2, although the face part having the effect of guiding, refracting, and diffusing light provided on the indoor surface of the ceiling panel is thin, an illumination box having an inspection port at the edge However, since it protrudes downward from the ceiling, it has not been partially reduced in thickness, and since it has an inspection port, there has been a problem that design restrictions occur.

この発明は上記のような従来技術の課題を解消するためになされたもので、照明装置の薄型化を図ることにより、エレベータのかご室の天井部厚さを薄くして建築側の省スペース化またはかご室空間の拡大が可能で、しかも意匠上の制約も少ないエレベータかご室の照明装置を提供することを目的としている。   The present invention has been made to solve the above-described problems of the prior art, and by reducing the thickness of the lighting device, the ceiling portion of the elevator cab is made thinner so that the space on the building side can be saved. Alternatively, it is an object of the present invention to provide an illuminating device for an elevator cab that can expand the cab space and has few design restrictions.

この発明によるエレベータかご室の照明装置は、エレベータのかご室を形成する天井の意匠面部材よりもそれぞれ天井裏側に設けられ、側端面から入射された光を照射面から出射する導光板、この導光板の上記側端面に対向して配設された光源部、並びにこれら導光板及び光源部の水平方向外側に設けられた上記光源部の点灯回路と、上記導光板の外周部に沿って枠状に形成され、該外周部近傍の下部に着脱可能に設けられるとともに、その少なくとも一部が上記光源部の垂直下方に配置され、上記光源部から上記かご室内の方向への直接光を遮蔽する照明カバー枠と、を備えるようにしたものである。
The lighting device for an elevator cab according to the present invention is provided on the back side of the ceiling with respect to the design surface member of the ceiling that forms the elevator cab, and a light guide plate that emits light incident from the side end surface from the irradiation surface. A light source unit disposed opposite to the side end surface of the light plate, a lighting circuit of the light source unit provided on the light source plate and the light source unit in the horizontal direction, and a frame shape along the outer periphery of the light guide plate And is detachably provided at the lower part in the vicinity of the outer peripheral part, and at least a part thereof is arranged vertically below the light source part and shields direct light from the light source part in the direction of the car room. And a cover frame .

この発明においては、導光板、光源部、及び点灯回路を天井の意匠面部材よりもそれぞれ天井裏側に水平方向に設けるようにしたことにより、照明装置を薄型化することができ、従ってエレベータかご室の天井部の厚さを薄くできる。このため、建築側の省スペース化ないしはかご室空間の拡大が可能となり、しかも天井意匠面よりも天井裏側に配設されることで下方向へのせり出しも無くすことができ意匠上の制約も少ないエレベータかご室の照明装置が得られる。   In this invention, since the light guide plate, the light source unit, and the lighting circuit are provided in the horizontal direction on the back side of the ceiling with respect to the design surface member of the ceiling, the lighting device can be thinned, and thus the elevator cab Can reduce the thickness of the ceiling. For this reason, it is possible to save space on the building side or expand the space of the car room, and it is possible to eliminate the downward protrusion by arranging it on the back side of the ceiling rather than the ceiling design surface, and there are few design restrictions A lighting device for an elevator cab is obtained.

図において、エレベータのかご室1の天井部2に設けられた照明装置3は、四角形の導光板31、この導光板31の少なくとも一つの側端面31aに対向して設けられ、出射光を該側端面31aから導光板31の内部に入射させる光源部としての蛍光ランプ32、及びこれら導光板31及び蛍光ランプ32の水平方向外側に設けられた点灯回路33からなり、これらは天井部2の意匠面部材21と、天蓋部材を兼用した照明器具天板22との高さ寸法H(図4)内のスペースに収められるように水平方向に配設され、強度上および光源部としての蛍光ランプ32の形状を考慮した必要最小限の高さを有する枠状に形成された天井補強材23の内側に設けられている。   In the figure, an illuminating device 3 provided on a ceiling portion 2 of an elevator cab 1 is provided to face a rectangular light guide plate 31 and at least one side end face 31a of the light guide plate 31, and emit light to the side. A fluorescent lamp 32 serving as a light source unit that enters the light guide plate 31 from the end surface 31a and a lighting circuit 33 provided outside the light guide plate 31 and the fluorescent lamp 32 in the horizontal direction are provided. It arrange | positions in a horizontal direction so that it may be stored in the space in the height dimension H (FIG. 4) of the member 21 and the lighting fixture top plate 22 which also serves as a canopy member, and the intensity | strength and the fluorescent lamp 32 as a light source part It is provided inside a ceiling reinforcing material 23 formed in a frame shape having a minimum height considering the shape.

上記蛍光ランプ32は、天井の薄型化を実現させるため、例えばインバータ方式の点灯回路33を用いた高出力のスリムランプなどが好ましく用いられ、この例では導光板31の対辺を形成する一対の側端面31aを挟み込むように2本配設されている。具体的には管径16mmの高周波点灯専用細管蛍光ランプ(例えば、蛍光ランプ型名FHF24)などを好ましく用いることができる。該細管の蛍光ランプ32は、従来の同等ワット数の管径29mmの一般照明用蛍光ランプ、例えば型名FL20Sの全光束1230ルーメンに対し、全光束1950ルーメン(周囲温度35℃)を有し、従来の約1.6倍の明るさがあり、寿命も従来の一般照明用蛍光ランプの定格寿命6000Hrに対し9000Hrと、約1.5倍の長寿命であるため有利である。なお、上記光源部として例示した蛍光ランプ32は、冷陰極蛍光ランプ、もしくは同様の他の蛍光ランプ類を使用しても差し支えない。   As the fluorescent lamp 32, for example, a high-power slim lamp using an inverter type lighting circuit 33 is preferably used in order to realize a thin ceiling, and in this example, a pair of sides forming opposite sides of the light guide plate 31 is used. Two are arranged so as to sandwich the end face 31a. Specifically, a high-frequency lighting-use thin tube fluorescent lamp (for example, a fluorescent lamp model name FHF24) having a tube diameter of 16 mm can be preferably used. The thin fluorescent lamp 32 has a total luminous flux of 1950 lumens (ambient temperature 35 ° C.) compared to a conventional general fluorescent lamp with an equivalent wattage of 29 mm in diameter, for example, a total luminous flux of 1230 lumens of model name FL20S. The brightness is about 1.6 times that of the conventional one, and the lifetime is 9000 Hr, which is about 1.5 times longer than the rated life of 6000 Hr of the conventional general illumination fluorescent lamp, which is advantageous. The fluorescent lamp 32 exemplified as the light source unit may be a cold cathode fluorescent lamp or other similar fluorescent lamps.

上記蛍光ランプ32の近傍には、天蓋補強を兼ねたランプ光反射板34が設置され、蛍光ランプ32の輝度効率の損失を抑えている。そして、蛍光ランプ32を点灯させる点灯回路33はインバータ方式のものが用いられ、天蓋部を兼用した照明器具天板22に固定され、図示省略しているインバータ等を構成する回路部品類は天井内部24側に格納されており、天井の上板を放熱板として利用している。また、上記インバータ方式の点灯回路33は、点滅回数による蛍光ランプ32の両端部に設けられた図示省略しているフィラメントの印加電流での負荷増におけるランプの短寿命化を防止するために、予熱回路(予熱時間は例えば乗場の呼びボタン始動から扉が開くまでの時間以内を想定して設定されている)を有するインバータ回路安定器が用いられている。なお、この例では保守点検時に照明器具天板22の上部に作業員が乗ることができる強度に構成されている。   In the vicinity of the fluorescent lamp 32, a lamp light reflecting plate 34 also serving as a canopy reinforcement is installed to suppress the loss of luminance efficiency of the fluorescent lamp 32. The lighting circuit 33 for turning on the fluorescent lamp 32 is of an inverter type, and is fixed to the lighting fixture top plate 22 that also serves as a canopy, and circuit components constituting the inverter and the like not shown in the figure are inside the ceiling. It is housed on the 24th side and uses the top plate of the ceiling as a heat sink. Further, the inverter type lighting circuit 33 is preheated in order to prevent the lamp from being shortened due to an increase in load due to an applied current of a filament (not shown) provided at both ends of the fluorescent lamp 32 depending on the number of blinks. An inverter circuit ballast having a circuit (the preheating time is set assuming that the time from the start of the call button on the hall to the time when the door opens) is used. In addition, in this example, it is comprised in the intensity | strength which an operator can get on the upper part of the lighting fixture top plate 22 at the time of a maintenance inspection.

上記導光板31としては、例えばアクリル樹脂などの透光性に優れ、軽量な樹脂材料からなる一般的なものを特別な制限無く用いることができ、上面部には側端面から入射された光をムラ無く下面部の照射面から出射させるための乱反射手段、上方向への光を下方向の照射面側へ向ける反射手段などが設けられているがここでは図示を省略している。一方、下面部の照射面側には、光の拡散機能を有し、意匠面を兼ねる例えばアクリル樹脂などからなる照明カバー31bが設けられている。さらに、蛍光ランプ32が配設されていない側端面には、図3に示すように反射部材31cが設けられ、これら導光板31、照明カバー31b、反射部材31cなどは固定手段4によって天井補強材23に固定されている。   As the light guide plate 31, for example, a general material made of a lightweight resin material having excellent translucency, such as acrylic resin, can be used without any particular limitation, and light incident from the side end surface is applied to the upper surface portion. There are provided irregular reflection means for emitting light from the irradiation surface of the lower surface without unevenness, reflection means for directing light upward to the irradiation surface side in the downward direction, etc., but illustration is omitted here. On the other hand, an illumination cover 31b made of, for example, an acrylic resin that has a light diffusion function and also serves as a design surface is provided on the irradiation surface side of the lower surface portion. Further, as shown in FIG. 3, a reflection member 31 c is provided on the side end surface where the fluorescent lamp 32 is not provided. The light guide plate 31, the illumination cover 31 b, the reflection member 31 c and the like are fixed to the ceiling by the fixing means 4. 23 is fixed.

また、上記導光板31の外周囲近傍下部には、四角形の枠状の照明カバー枠35が配設され、蛍光ランプ32からエレベータのかご室1方向への直接光を遮蔽すると共に、固定手段4が下方から見えないように覆っている。該照明カバー枠35は、図5〜図11に示すように、天井補強材23に設けられた挿通穴23aに挿通された係止ばね36によって、上下移動可能、かつ着脱可能に天井補強材23に取り付けられている。なお、照明カバー枠35と係止ばね36とは、係止ばね36のループ部分36b(図10、図11)で図示省略している係合手段により係合されている。   In addition, a rectangular frame-shaped illumination cover frame 35 is disposed in the lower part of the vicinity of the outer periphery of the light guide plate 31 to shield direct light from the fluorescent lamp 32 toward the elevator car 1 and to the fixing means 4. Is covered so that it cannot be seen from below. As shown in FIGS. 5 to 11, the illumination cover frame 35 is vertically movable and detachable from the ceiling reinforcing member 23 by a locking spring 36 inserted into an insertion hole 23 a provided in the ceiling reinforcing member 23. Is attached. The illumination cover frame 35 and the locking spring 36 are engaged with each other by an engaging means not shown in the loop portion 36b (FIGS. 10 and 11) of the locking spring 36.

また、上記係止ばね36は、図10の矢印Dのように角度が広がる方向に付勢されており、照明カバー枠35を持ち上げたときには、図5、図7、図10に示すように意匠面部材21と照明カバー31bに当接するように照明カバー枠35を保持し、蛍光ランプ32の交換等で降下させたときには図6、図8、図9、図11に示すように係止ばね36の先端部に形成された抜け止め部36aが挿通穴23aの縁部に係止されることにより所定の間隔で降下状態を保持できる。さらに、所要時には抜け止め部36aを挿通穴23aから引き抜くことにより、照明カバー枠35を天井補強材23から取り外すことも可能に構成されている。而して、天井の上面、下面は突起部の少ない、ほぼ平面を成す薄型の照明装置付天井となっている。なお、図12において、5は昇降路、51は昇降路頂部、6は最上階の乗場、7はかご、71はかご上部、72はかご枠上部を示している。   Further, the locking spring 36 is urged in a direction in which the angle increases as indicated by an arrow D in FIG. 10, and when the lighting cover frame 35 is lifted, the design as shown in FIGS. When the illumination cover frame 35 is held so as to abut against the surface member 21 and the illumination cover 31b and lowered by exchanging the fluorescent lamp 32 or the like, as shown in FIGS. The retaining portion 36a formed at the distal end portion of the first member is locked to the edge portion of the insertion hole 23a, so that the lowered state can be maintained at a predetermined interval. Furthermore, the illumination cover frame 35 can be detached from the ceiling reinforcing member 23 by pulling out the retaining portion 36a from the insertion hole 23a when necessary. Thus, the upper surface and the lower surface of the ceiling are thin and have a thin flat lighting device with few protrusions. In FIG. 12, 5 is a hoistway, 51 is a hoistway top, 6 is a landing on the top floor, 7 is a car, 71 is a car upper part, and 72 is a car frame upper part.

次に、上記のように構成された実施の形態1の動作について説明する。蛍光ランプ32から出射された光は、反射板34により高効率に損失少なく導光板31の側端面31aから導光板31内に入射された後、図示省略している乱反射手段、反射手段により光ムラなく均一に面発光し、導光板31の下部に設けられた照明カバー31bに照射され、該照明カバー31bを介してかご室1内を照らす。光源部として用いる蛍光ランプ32の光出力の合計、照明器具3の設置台数等を適宜選ぶことにより従来のかご室の照度と同等以上の照度を得ることは容易である。   Next, the operation of the first embodiment configured as described above will be described. Light emitted from the fluorescent lamp 32 is incident on the light guide plate 31 from the side end surface 31a of the light guide plate 31 with high efficiency and little loss by the reflection plate 34, and then is unevenly reflected by irregular reflection means and reflection means (not shown). Instead, the light is emitted evenly and irradiated to the illumination cover 31b provided below the light guide plate 31, and the interior of the cab 1 is illuminated through the illumination cover 31b. By appropriately selecting the total light output of the fluorescent lamps 32 used as the light source unit, the number of installed lighting fixtures 3 and the like, it is easy to obtain an illuminance equivalent to or higher than the illuminance of a conventional cab.

また、照明カバー枠35はネジ等を用いた固定方式ではなく、通常時は図10に示すように係止ばね36の矢印D方向に付勢されたばね弾性力で挿通穴23a部に保持されており、蛍光ランプ32を交換する際などには、照明カバー枠35の周囲を係止ばね36の付勢力に抗して図11の矢印Eで示すように下向きに引き下げることにより降下させた状態で保持し、さらに必要によって取り外すことができ、取り外すための工具等は不要で、かご室1内から蛍光ランプ32の交換作業が容易にできる。そして、照明カバー31bと意匠面部材21は段差を少なく構成できるため、照明カバー枠35も薄型にでき、全体的に天井面の段差の少ない照明装置付天井部が構成され、意匠性を損ねることもない。   Further, the illumination cover frame 35 is not fixed using screws or the like, and is normally held in the insertion hole 23a portion by a spring elastic force urged in the direction of arrow D of the locking spring 36 as shown in FIG. When the fluorescent lamp 32 is replaced, the periphery of the illumination cover frame 35 is lowered by pulling downward as shown by an arrow E in FIG. 11 against the urging force of the locking spring 36. It can be held and further removed if necessary, and a tool or the like for removal is unnecessary, and the replacement work of the fluorescent lamp 32 from the inside of the car room 1 can be facilitated. And since the illumination cover 31b and the design surface member 21 can be configured with few steps, the illumination cover frame 35 can also be made thin, and the ceiling portion with the illumination device with few steps on the ceiling surface is formed as a whole, thereby impairing the design. Nor.

上記のように、実施の形態1によれば、照明装置3は導光板31、蛍光ランプ32、及び点灯回路33を分離して水平方向に配置していることにより、光源部である蛍光ランプ32と照明カバー31bとは必然的に水平方向にずれて配設されるため、蛍光ランプ32と照明カバー31bの間に上下方向の間隔を設ける必要はなく、特に高さ方向のスペースを最小限に押さえることができる。例えば、従来の蛍光ランプの下部に照明カバーを配設した照明付き天井の厚さ(約65mm)に比較して、約半分の厚さ(約30〜35mm程度)とした照明装置一体型天井を実現できる。このため、天井照明ボックスの深さ(高さ)Hを小さくして天井の厚さを薄くすることができ、エレベータレイアウト上、建築側の省スペース化に効果を発揮する。   As described above, according to the first embodiment, the illuminating device 3 separates the light guide plate 31, the fluorescent lamp 32, and the lighting circuit 33 and arranges them in the horizontal direction, so that the fluorescent lamp 32 that is a light source unit. And the illumination cover 31b are inevitably disposed in the horizontal direction, so there is no need to provide a vertical space between the fluorescent lamp 32 and the illumination cover 31b, and the space in the height direction is particularly minimized. I can hold it down. For example, an illumination device-integrated ceiling having a thickness (about 30 to 35 mm) that is about half of the thickness (about 65 mm) of the illuminated ceiling in which the illumination cover is disposed below the conventional fluorescent lamp. realizable. For this reason, the depth (height) H of the ceiling lighting box can be reduced to reduce the thickness of the ceiling, which is effective in saving space on the building side in terms of the elevator layout.

即ち、図12に示すように、昇降路5における最上階の乗場6に停止した状態のかご7において、かご上部71からかご枠上部72までの寸法Mは、かご上部71とかご枠上部72間に配設される機器の実装上、一定寸法必要である。また、かご枠上部72から昇降路頂部51までの寸法Nは、法規等で最小寸法が規定されている。そこで、M、N寸法が任意の一定寸法である場合、天井厚さHが小さくなると、次のような効果が得られる。   That is, as shown in FIG. 12, in the car 7 stopped at the landing 6 on the top floor in the hoistway 5, the dimension M from the car upper part 71 to the car frame upper part 72 is between the car upper part 71 and the car frame upper part 72. A certain size is required for mounting of the equipment to be installed. Further, the minimum dimension of the dimension N from the car frame upper part 72 to the hoistway top 51 is defined by laws and regulations. Therefore, when the M and N dimensions are arbitrary constant dimensions, the following effects can be obtained when the ceiling thickness H is reduced.

1)従来とかご室内高さKを同一とした場合、かご高さLは小さくなる。
そのため、昇降路5の全高Pを小さくすることが可能となり、建築側のスペースを減少することができ、建築スペースの有効利用が図れる。
2)また、かご高さLを従来と同一とした場合は、天井厚さHが小さくなる分、かご室1内高さKを大きくすることが可能であるため、かご室1内容積が増大し、開放感が増す。
1) When the car interior height K is the same as the conventional car, the car height L is reduced.
Therefore, the total height P of the hoistway 5 can be reduced, the space on the building side can be reduced, and the building space can be effectively used.
2) In addition, when the car height L is the same as that of the conventional car, the height K in the car room 1 can be increased as the ceiling thickness H becomes smaller, so the volume in the car room 1 increases. And the feeling of opening increases.

さらに、蛍光ランプ32からの直接光が照明カバー枠35によって遮蔽され、導光板31による面発光によってかご室1内が照明されるので、ランプの輝度による光ムラが解消され、意匠性も向上する。上記のように、『天井を照明器具とした一体天井』とした構成により、製造コストの低減、組立作業の削減、ランプ交換の容易化を図ることができる。また、上記点灯回路33はインバータ回路安定器を照明付き天井としてユニット化して構成することにより、組立工数の低減化を図ることもできる。   Furthermore, since the direct light from the fluorescent lamp 32 is shielded by the illumination cover frame 35 and the interior of the cab 1 is illuminated by the surface light emission by the light guide plate 31, the light unevenness due to the brightness of the lamp is eliminated and the design is improved. . As described above, the configuration of the “integrated ceiling with the ceiling as a lighting fixture” can reduce manufacturing costs, reduce assembly work, and facilitate lamp replacement. Further, the lighting circuit 33 can be configured by unitizing the inverter circuit ballast as a ceiling with illumination, thereby reducing the number of assembly steps.

実施の形態2.
図13、図14はこの発明の実施の形態2による照明装置を示すもので、図13は天井部に取り付けられた照明装置を天井上方から見た平面図、図14は要部を拡大して示す断面図で、実施の形態1の図4に相当する図である。この実施の形態2による照明装置は、光源部として、実施の形態1で用いた蛍光ランプ32の代わりに白色LEDランプを側端面31aに沿って配列したLEDランプユニット37を用いたものである。図に示すように、導光板31における対辺部の両側端面31aには、任意の間隔(例えば10〜30mmピッチ)で多数の白色LEDランプ37aが1列または複数列に配置されている。そして、水平方向側方部には、LEDランプ37aを点灯させるための点灯回路としての電源部38が配設されている。その他の構成は上記実施の形態1と同様であるので、説明を省略する。

FIGS. 13 and 14 show a lighting device according to Embodiment 2 of the present invention. FIG. 13 is a plan view of the lighting device attached to the ceiling as viewed from above the ceiling. FIG. It is sectional drawing shown, and is a figure equivalent to FIG. 4 of Embodiment 1. FIG. The illumination device according to the second embodiment uses, as a light source unit, an LED lamp unit 37 in which white LED lamps are arranged along the side end face 31a instead of the fluorescent lamp 32 used in the first embodiment. As shown in the drawing, a large number of white LED lamps 37a are arranged in one or a plurality of rows at arbitrary intervals (for example, a pitch of 10 to 30 mm) on both side end surfaces 31a of the opposite sides of the light guide plate 31. A power supply unit 38 as a lighting circuit for lighting the LED lamp 37a is disposed on the side portion in the horizontal direction. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

上記のように構成された実施の形態2においては、上記実施の形態1と同様の動作により導光体31が均一に面発光して図示省略しているかご室内をソフトに明るく照らし、同様の効果が得られる他、光源部として白色LEDを用いていることにより、発熱や、消費電力が蛍光ランプよりも少なく、省エネも実現でき、さらに一層の薄型化が可能であるという効果が得られる。また、発光色の異なるLEDランプ、例えば赤色、緑色、青色に発光する3種類のLEDランプを水平方向にマトリックス状に配置し、例えば図示省略しているかご制御盤等にコントローラを設け、該コントローラにより点灯回路としての電源部38を介して、各色のLEDランプの輝度を制御できるように構成することにより、エレベータの設置後、所望により白色を含む任意の色の照明光を得ることができ、運行サービスの時間帯や納入先の希望などに応じて任意に発光色が変えられる等、特異の照明効果を得ることもできる。   In the second embodiment configured as described above, the light guide 31 uniformly emits light by the same operation as in the first embodiment, and the interior of the car that is not illustrated is softly illuminated brightly. In addition to the effect, the use of the white LED as the light source part has the effect that heat generation, power consumption is less than that of the fluorescent lamp, energy saving can be realized, and further reduction in thickness is possible. Further, LED lamps having different emission colors, for example, three types of LED lamps emitting red, green, and blue, are arranged in a matrix in the horizontal direction, and a controller is provided in a car control panel, for example, not shown, By configuring so that the brightness of each color LED lamp can be controlled via the power supply unit 38 as a lighting circuit, after installation of the elevator, it is possible to obtain illumination light of any color including white if desired, A unique lighting effect can be obtained, for example, the light emission color can be changed arbitrarily according to the time zone of the operation service or the request of the delivery destination.

なお、上記実施の形態の説明では、導光板31の対向する2つの側端面31aに光源部を設けたが、これに限定されるものではなく、必要とする光量等に応じて1つの側端面のみに配設し、あるいは4つの側端面全てに配設するなど適宜変更できることは言うまでも無い。また、導光板31として4角形のものを用いたが、例えば円形、楕円形など所望の任意の形状とすることができる。この場合、光源部としては、導光板の側端面の形状に沿うように形成されたランプ、またはランプユニットが好ましく用いられる。また、点灯回路として、蛍光ランプではインバータ、LEDランプでは電源部を用いたが、これらのみに限定されるものではない。その他、種々の変形や変更が可能であることは言うまでも無い。   In the description of the above embodiment, the light source portion is provided on the two opposing side end surfaces 31a of the light guide plate 31. However, the present invention is not limited to this, and one side end surface is provided depending on the amount of light required. Needless to say, it can be changed as appropriate, for example, only on the four side end surfaces. Moreover, although the rectangular thing was used as the light-guide plate 31, it can be set as desired arbitrary shapes, such as circular and an ellipse, for example. In this case, as the light source unit, a lamp or a lamp unit formed so as to follow the shape of the side end face of the light guide plate is preferably used. Further, as the lighting circuit, an inverter is used in the fluorescent lamp and a power supply unit is used in the LED lamp. However, the lighting circuit is not limited thereto. Needless to say, various modifications and changes can be made.
