【考案が解決しようとする課題】[Problems to be solved by the invention]

図３に示す直付け型の天井用照明器具においては、蛍光灯あたりの反射平面が 一つであり集光効果が低く、反射平面は白色塗装が施されているが照明光の反射 効果が低く、照明が拡散されてしまい充分な照度を得ることができない。直付け 型は天井より下方に突出する構造であるため、上下方向のサイズを小さくするこ とが要求される。蛍光灯の照明光の一部を天井に照明させるとともに、消費電力 を増加させることなく著しく照度を高めることができる直付け型の天井用照明器 具を提供することを目的としている。 The ceiling-mounted lighting fixture shown in Fig. 3 has only one reflecting surface per fluorescent lamp and has a low light-collecting effect, and the reflecting surface is painted white, but the reflecting effect of illumination light is low. However, the illumination is diffused and it is not possible to obtain sufficient illuminance. Since the direct mounting type has a structure that protrudes below the ceiling, it is necessary to reduce the size in the vertical direction. An object of the present invention is to provide a ceiling-mounted lighting device of a direct mounting type capable of illuminating a part of the illumination light of a fluorescent lamp on a ceiling and significantly increasing illuminance without increasing power consumption.

【実施例】【Example】

実施例について図面を参照して説明する。 図１は本考案の一実施例を示すものである。２本の直線形の蛍光灯（２）を水平 面に平行して設け、上方に２本の蛍光灯（２）の間隔よりも幅広とし、且つ、蛍 光灯（２）の長さに対応させて反射板（１）を設ける。反射板（１）は取り付け 器具（４）にネジで固定されている。蛍光灯（２）は取り付け器具（４）に設け られているソケット（５）により保持される。反射板（１）の下面は鏡面加工さ れた反射面とし、折曲げ部により１本の蛍光灯（２）あたり４つの反射平面から 構成され、４つのうち３つの反射平面は蛍光灯（２）の外径よりも幅広に設けら れ、各反射平面に直角で各反射平面の中央を通る直線が各反射面下方の１点で交 叉するように各反射面の傾きが設定されている。反射板（１）の左右端は蛍光灯 （２）の上端より上位に、反射板（１）の下端は蛍光灯（２）の下端より下位に 設けられている。蛍光灯（２）あたり、反射平面間の角度を１６０度±１０度に 設け、反射板（１）の上端と下端間の上下方向のサイズを蛍光灯（２）外径の１ ．５倍のサイズ以下に設け、蛍光灯（２）を反射平面に近接させ設ける。このよ うにして蛍光灯（２）の上方に反射板（１）を取り付けた状態で蛍光灯（２）を 使用すると蛍光灯（２）から発した照明光は反射板（１）の下面に形成され、反 射、集光効果を高めた鏡面反射平面により反射、集光されて下方を照らすため、 蛍光灯（２）の発光量が効率的に利用されることにより照度を著しく高めること ができる。蛍光灯（２）から発した照明光の一部は反射板（１）の左右端付近か ら天井方向へも照射される。 蛍光灯の長さに対応させて設けた白色系塗装を施した凹形状の反射板を蛍光灯の 長さに対応させて設けた反射板と直線形蛍光灯を組み合わせた従来の天井用照明 器具において、上方への光線を反射板が遮断してしまう構造のため発生する天井 面が暗くなるという問題点を除去することができる。 Embodiments will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. Two linear fluorescent lamps (2) are provided in parallel with the horizontal plane, are wider than the interval between the two fluorescent lamps (2), and correspond to the length of the fluorescent lamps (2). Then, the reflection plate (1) is provided. The reflector (1) is fixed to the mounting device (4) with screws. The fluorescent lamp (2) is held by a socket (5) provided on the mounting device (4). The lower surface of the reflecting plate (1) is a mirror-finished reflecting surface, and is formed of four reflecting planes per fluorescent lamp (2) by a bent portion, and three of the four reflecting planes are fluorescent lamps (2). ) Is provided wider than the outer diameter of), and the inclination of each reflection surface is set so that a straight line passing through the center of each reflection plane at right angles to each reflection plane intersects at one point below each reflection surface. .

For the fluorescent lamp (2), the angle between the reflecting planes is set at 160 ° ± 10 °, and the size in the vertical direction between the upper end and the lower end of the reflector (1) is set to 1. The fluorescent lamp (2) is provided close to the reflection plane and provided at a size of 5 times or less. When the fluorescent lamp (2) is used with the reflector (1) attached above the fluorescent lamp (2) in this way, the illumination light emitted from the fluorescent lamp (2) is applied to the lower surface of the reflector (1). It is formed, reflected and condensed by a specular reflection plane with enhanced reflection and condensing effects, and illuminates the lower part. Therefore, the luminous intensity of the fluorescent lamp (2) can be significantly increased by efficiently using the light emission amount. it can. Part of the illumination light emitted from the fluorescent lamp (2) is also emitted from the vicinity of the left and right ends of the reflector (1) toward the ceiling. Conventional ceiling lighting fixtures that combine a straight reflector with a reflector with a white paint applied to match the length of the fluorescent lamp and a reflector that matches the length of the fluorescent lamp In this case, it is possible to eliminate the problem that the ceiling surface becomes dark due to the structure in which the reflector blocks the light rays upward.

【考案の効果】[Effect of the invention]

本考案は、以上述べたように構成されているので以下に述べるような効果があ る。一つの蛍光灯につき４つの鏡面加工した反射平面を、うち３つは該蛍光灯の 径より広幅とした反射平面を凹形状に設けることにより反射効率、集光効果を高 めることができる。また、反射板の左右端を該蛍光灯の上位に設けることにより 該蛍光灯から発する光の一部が反射板により遮断されることなく天井面を照らす ので、天井面が暗くなるという違和感を与えない。そして蛍光灯あたり、反射平 面間の角度を１６０度±３度に設け、反射面の上端と下端間の上下方向のサイズ を蛍光灯径の１．５倍のサイズ以下に設け、蛍光灯を反射平面に近接させ設ける ことにより天井より下方に突出する部分のサイズを小さくすることができる。 The present invention is configured as described above and has the following effects. The reflection efficiency and the light-collecting effect can be improved by providing four mirror-finished reflection planes for one fluorescent lamp and providing three concave reflection planes wider than the diameter of the fluorescent lamp. Also, by providing the left and right ends of the reflector above the fluorescent lamp, part of the light emitted from the fluorescent lamp illuminates the ceiling without being blocked by the reflector, giving a sense of incongruity that the ceiling becomes dark. Absent. The angle between the reflecting planes is set at 160 ° ± 3 ° per fluorescent lamp, and the vertical size between the upper end and the lower end of the reflecting surface is set to be 1.5 times or less the diameter of the fluorescent lamp.
