Description

【０００１】
【発明が属する技術分野】
本発明は、蛍光管を照明灯に用いて、その蛍光管を照明器具の器具本体となる取付台に取り付け、その取付台を天井につり下げて装設するようにする天井つり下げ灯において、特に、蛍光管を取付台の上面側に下方から見えないように取り付けて間接照明式とする天井つり下げ灯の取付台についての改良に関する。
【０００２】
【従来の技術】
照明灯に蛍光管を用いた天井つり下げ灯は、従前のものは、大半が、天井につり下げる器具本体である取付台の下面側に、蛍光管を裸出する状態として取り付けている形態のものであり、蛍光管を取付台の上面側に、下方から見えないように取り付けて、間接照明式の天井つり下げ灯としたものは極く少ない。
【０００３】
【発明が解決しようとする課題】
照明灯に蛍光管を用いた天井つり下げ灯は、器具本体である取付台に照明灯として組み付ける蛍光管が長大な形状のものとなることと、反射光を得るために取付台に取り付ける反射板が蛍光管に対応して長大なものとなること、また、取付台には、蛍光管の端子に接続するソケットおよびそれを組み付ける端子台ならびに安定器を組み付けることから、その取付台が、長大で、しかも、上下の深さ寸法の深い箱状のものとなる。
【０００４】
このため、蛍光管を取付台の上面側に取り付けて間接照明式の天井つり下げ灯とするときは、取付台を、天地を逆転させた裏返しの状態として吊り下げることで、この深さ寸法の深い、かつ、横方向に長大な箱状の取付台が、天井から吊り下がるようになることで、著しく存在感のあるものとなり、室内にいる居住者に対し圧迫感を与え、また、存在感のある巨大なものが吊り下がったようになることで、邪魔物の感じが大きく使用が好まれない問題がある。
【０００５】
この問題は、長大な箱状に形成されていることで、天地を逆にした裏返しにした形態として吊り下げると、存在感の大きいものとなって、圧迫感を受けるようになる取付台を、例えば、薄い棚板状のものに成形することで、解決し得るようになるが、そのようにすると、蛍光管および各機器を組み付けるこの取付台の強度が不足して、安住に設置し得ないようになる別の問題がでてくる。
【０００６】
本発明は、この蛍光管を用いた天井つり下げ灯を、間接照明式の形態に構成するときに生じている上述の問題を解消せしめるためになされたものであって、蛍光管・反射板・端子台・安定器などの機器を組み付ける器具本体となる取付台を、薄い棚板状または化粧板状に形成して、圧迫感を受けないものとしながら、組み付ける各機器の保持が適確に行える充分な強度のものに構成し得るようにする新たな手段を提供することを目的とする。
【０００７】
【課題を解決するための手段】
蛍光管を照明灯に用いた天井つり下げ灯を、間接照明式としたときに、蛍光管・安定器等の機器を取り付ける取付台が、存在感の大きい、圧迫感を受けるものとなるのは、その取付台が長大な箱状に形成されているためであって、この取付台を、底面がフラットな薄い棚板状乃至化粧板状に形成して、それの上面側に、蛍光管・反射板・ソケット・端子台・安定器などの諸機器を組み付けるようにし、この取付台を、吊り下げ金具により天井に吊り下げるようにすれば、間接照明式の天井つり下げ灯として建物の室内に設置したときに、諸機器を組み付ける取付台が、室内の居住者に対して圧迫感を与えることのないものとなることが判ってきた。
【０００８】
そして、このように薄い棚板状乃至化粧板状に取付台を形成するとき、その取付台を、アルミ材または鋼材などの金属材の押し出し成形により長尺の板状に形成するようにし、その押し出し成形の際、取付台上面側に、そこに組み付ける蛍光管の照明光を天井面に向け反射させるように装設する反射板を、この取付台の補強リブとして一体に連続させて成形し、また、諸機器を組み付けるための組付座を、取付台を補強するリブとなる形態のものとして一体に連続させて成形するようにし、かつ、これら補強リブとする反射板およびリブ状の組付座が、所定の断面形状をもって取付台の長手方向に連続する形態として取付台と一緒に押し出し成形するようにすることで、この取付台を上下の深さ方向に薄い棚板状に形成しながら、諸機器を組み付け装架するのに充分な強度のものとし得るものとなることが判ってきた。
【０００９】
そして、このことから、本発明においては、請求項１に記載したように、上面側に、蛍光管・反射板・端子台・安定器等の諸機器を組み付ける取付台を、アルミ材・鋼材等の金属材により、下面側をフラットとした長尺の平板状の板部材に形成し、その板部材の上面側に、内面側を組み付ける蛍光管の照明光の反射板とする突条と、諸機器組付用の組付座を構成する突条とを、板部材に一体に連続してその板部材から上面側に突出し、かつ、当該突条の断面形状をもって板部材の長手方向に連続する形状に形設して構成した手段を提起するものである。
【００１０】
また、蛍光管を照明灯に用いる間接照明式の天井つり下げ灯の取付台を、それの上面側に組み付ける蛍光管の反射板および諸機器の組付座が、取付台を補強リブとなるように一体に連続させて押し台成形して上下の深さ寸法が小さい平板状の長尺板に構成し、これにより、この取付台を室内の天井につり下げ設置したときに、圧迫感を受けないようにする際、この取付台の上面側に組み付ける蛍光管が２連に並列する形態のものとして照度を増大させる場合には、この２連に並列させて組み付ける蛍光管の照明光を天井面に向け反射させるように取付台の上面に設ける反射板を、取付台の上面の巾方向における中央に寄せた部位に、２連に並列させて補強リブ状に突出する形態に装設するときに、これら２連の反射板と反射板との間に所定の空間が形成されるようにこれら反射板を形設し、その反射板と反射板との間に、諸機器の組付用の組付座を取付台の上面からリブ状に突出するように装設しておくことで、このリブ状の組付座を用いて安定器・端子台などの諸機器を重量バランスを良い状態として組み付けられるようになり、また、天井から垂下させる吊り金具に対して連結させるアンカー金具により、バランスよく取付台を吊り下げられることが判ってきた。
【００１１】
そして、このことから、請求項２に記載した手段を併せて提起するものである。
【００１２】
【発明の実施の形態】

[Technical field to which the invention belongs]
The present invention uses a fluorescent tube as an illuminating lamp, attaches the fluorescent tube to a mounting base that is a fixture body of a lighting fixture, and suspends the mounting base from the ceiling so as to be installed. In particular, the present invention relates to an improvement on a ceiling hanging lamp mounting base that is mounted on the upper surface side of the mounting base so as not to be seen from below and is an indirect illumination type.
[0002]
[Prior art]
Most of the ceiling hanging lamps that use fluorescent tubes as illumination lamps are in the form that the fluorescent tubes are barely mounted on the lower surface side of the mounting base that is the main body of the fixture that is suspended from the ceiling. There are very few indirect-illuminated ceiling hanging lights that are mounted on the upper surface of the mounting base so that they cannot be seen from below.
[0003]
[Problems to be solved by the invention]
Ceiling hanging lamps that use fluorescent tubes as illumination lamps have a long fluorescent tube assembled as an illumination lamp on a mounting base that is the main body of the fixture, and a reflector that is attached to the mounting base to obtain reflected light Is a long one corresponding to the fluorescent tube, and the mounting base is mounted with a socket connected to the terminal of the fluorescent tube, a terminal block for assembling it, and a ballast. And it becomes a box-shaped thing with a deep vertical dimension.
[0004]
For this reason, when attaching a fluorescent tube to the top side of the mounting base to make an indirect-illumination ceiling hanging lamp, suspend the mounting base upside down so that this depth dimension is The deep and laterally long box-shaped mounting base hangs from the ceiling, so it has a significant presence, giving a sense of pressure to residents in the room, and also presenting There is a problem that a huge thing with a hung is like hanging, and the feeling of a disturbing thing is large and the use is not preferred.
[0005]
This problem is that it is formed in a long box shape, and if it is suspended as an inverted version with the top and bottom turned upside down, it will have a large presence and a mounting base that will receive a feeling of pressure, For example, it can be solved by forming it into a thin shelf-like shape, but if it does so, the strength of this mounting base for assembling the fluorescent tube and each device is insufficient, and it can not be installed safely Another problem comes up.
[0006]
The present invention was made to solve the above-mentioned problems that occur when a ceiling hanging lamp using this fluorescent tube is configured in an indirect illumination type, and includes a fluorescent tube, a reflector, The mounting base, which is the main body of the equipment for assembling equipment such as terminal blocks and ballasts, is formed into a thin shelf or decorative board so that it does not receive a feeling of pressure, but it can accurately hold each equipment to be assembled. It is an object of the present invention to provide a new means that can be constructed to have a sufficient strength.
[0007]
[Means for Solving the Problems]
When the ceiling hanging lamp that uses a fluorescent tube as an illuminating lamp is an indirect lighting type, the mounting base for mounting equipment such as a fluorescent tube and ballast will have a strong presence and a feeling of pressure. This is because the mounting base is formed in a long box shape, and this mounting base is formed in a thin shelf plate shape or a decorative plate shape with a flat bottom surface, and a fluorescent tube Assemble various devices such as reflectors, sockets, terminal blocks, ballasts, etc., and suspend this mounting base from the ceiling with hanging brackets. When installed, it has been found that the mounting base for assembling the various devices does not give a feeling of pressure to the occupants in the room.
[0008]
And when the mounting base is formed in such a thin shelf shape or decorative board shape, the mounting base is formed into a long plate shape by extrusion molding of a metal material such as an aluminum material or a steel material, At the time of extrusion molding, on the upper surface side of the mounting base, a reflecting plate that is installed so as to reflect the illumination light of the fluorescent tube assembled thereon toward the ceiling surface is integrally formed as a reinforcing rib of this mounting base, In addition, an assembly seat for assembling various devices is integrally formed continuously as a rib that reinforces the mounting base, and the reflector and rib-like assembly as these reinforcing ribs. While the seat is extruded and molded together with the mounting base in a form that has a predetermined cross-sectional shape in the longitudinal direction of the mounting base, the mounting base is formed into a thin shelf in the vertical direction , Various devices Be assumed that be of a sufficient strength to attach mounted has been found.
[0009]
From this, in the present invention, as described in claim 1, the mounting base for assembling various devices such as a fluorescent tube, a reflector, a terminal block, and a ballast on the upper surface side is made of an aluminum material, a steel material, or the like. the metal material to form a lower surface side on a flat plate member elongated and flat, the upper surface side of the plate member, the ridge of the reflecting plate of the illuminating light of a fluorescent tube for assembling the inner surface side, various The ridges constituting the assembly seat for assembling the device are continuously integrated with the plate member and protrude from the plate member to the upper surface side, and continue in the longitudinal direction of the plate member with the cross-sectional shape of the ridge. It proposes a means that is configured in a shape.
[0010]
In addition, the mounting plate of the fluorescent tube reflecting lamp and various devices that attach the mounting base of the ceiling hanging lamp of the indirect illumination type using the fluorescent tube as the illuminating lamp to the upper surface side of the mounting base becomes a reinforcing rib. Is formed into a plate-like long plate with a small vertical depth, and when this mounting base is suspended and installed on the ceiling in the room, a feeling of pressure is received. When the illuminance is increased when the fluorescent tubes assembled on the upper surface side of the mounting base are arranged in parallel with each other when increasing the illuminance, the illumination light of the fluorescent tubes assembled in parallel with the two tubes is used as the ceiling surface. When mounting the reflector provided on the upper surface of the mounting base so as to be reflected toward the center, in a form protruding in the form of a reinforcing rib in parallel with the portion of the upper surface of the mounting base that is close to the center in the width direction , A predetermined distance between the two reflectors and the reflectors. These reflectors are formed so that a gap is formed, and an assembly seat for assembling various devices is mounted between the reflector and the reflector so as to protrude in a rib shape from the upper surface of the mounting base. By installing it, it will be possible to assemble various devices such as ballasts and terminal blocks with a good weight balance using this rib-shaped assembly seat. It has been found that the mounting base can be suspended in a well-balanced manner by the anchor metal fittings to be connected.
[0011]
And from this, the means described in claim 2 is also proposed.
[0012]
