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

ところで、塗装ラインにおいては、部分的に手塗り作業が残っているのが現状 である。従って、そのような場所には、集光性をもたせた照明器具を配置して、 作業対象である被照射体を高照度で照明するといった手法を採用しているが、こ の場合、被照射体以外の空間の照明が暗くなり、全体としての環境性が悪く、し かも、被照射体以外の場所での作業性が悪くなる。 By the way, in the coating line, the current situation is that part of the manual coating work remains. Therefore, in such a place, a method of arranging a lighting device having a light condensing property to illuminate the irradiation target, which is the work target, with high illuminance is used. The lighting of the space other than the body becomes dark, and the environment is not good as a whole, and workability in places other than the irradiated body is poor.

【0004】 その対策としては、全体照明用の照明器具を別途に設置すればよいが、その器 具および設置工事費等のイニシャルコストならびにランニングコスト面において の問題が新たに発生する。As a countermeasure, a lighting fixture for total lighting may be separately installed, but a new problem arises in terms of the equipment and initial cost such as installation work cost and running cost.

【0005】 本考案はこのような事情に鑑みてなされたもので、その目的とすることは、特 定の領域を高照度で照明でき、さらに全体的に均整のとれた照明効果を得ること のできる照明器具を提供することにある。The present invention has been made in view of the above circumstances, and it is an object of the present invention to illuminate a specific area with high illuminance and to obtain an evenly balanced lighting effect. The purpose is to provide a lighting device that can.

【実施例】【Example】

図1は本考案実施例の構造を示す図で、(a) および(b) はそれぞれ縦断面図お よび外観斜視図である。 FIG. 1 is a view showing the structure of an embodiment of the present invention, in which (a) and (b) are a longitudinal sectional view and an external perspective view, respectively.

【0009】 器具本体1の前面側には、この器具全体を壁もしくは天井などに取り付けるた めの装着フランジ11が設けられている。また、器具本体11の前面側には、透 明ガラス製で、かつ開閉が自在な構造の前面カバー12が装着されている。A mounting flange 11 is provided on the front side of the instrument body 1 for attaching the entire instrument to a wall or ceiling. A front cover 12 made of transparent glass and having a structure that can be opened and closed is attached to the front side of the instrument body 11.

【0010】 さて、器具本体1は、5本の直管型蛍光ランプ2a・・2eを装着する構造とな っており、そのうち下側の3本の蛍光ランプ2a,2bおよび2cの装着位置に 相当する部分の後方側に集光用反射笠3が配置されており、その残りの蛍光ラン プ2d,2eの装着位置に相当する部分の後方側に拡散用反射笠4が配置されて いる。The instrument main body 1 has a structure in which five straight tube fluorescent lamps 2a, 2e are mounted, and the lower three fluorescent lamps 2a, 2b and 2c are mounted at the mounting positions. The condensing reflection shade 3 is arranged on the rear side of the corresponding portion, and the diffusion reflection shade 4 is arranged on the rear side of the portion corresponding to the mounting positions of the remaining fluorescent lamps 2d and 2e.

【0011】 集光用反射笠3は、縦断面形状を波形状とした集光性のある反射板で、3本の 蛍光ランプ2a,2bおよび2cから光を、それぞれ前方斜め下方に向けて反射 する。また、この集光用反射笠3の反射面には、例えば銀蒸着シートの貼着など によって、その反射率が90%程度にまで高められている。The light-collecting reflector 3 is a light-reflecting reflector having a wavy vertical cross-section and reflects light from the three fluorescent lamps 2a, 2b, and 2c, respectively, in a diagonally forward and downward direction. To do. The reflectance of the light-collecting reflective shade 3 is increased to about 90% by, for example, attaching a silver vapor deposition sheet.

【0012】 一方、拡散用反射笠4は、事務所などの照明器具に一般に用いられるものと同 等な白色の平板で、2本の蛍光ランプ2d,2eからの光を種々の方向に向けて 乱反射する。その反射率は60〜65%程度である。On the other hand, the diffusing reflection shade 4 is a white flat plate similar to that generally used for lighting equipment such as offices, and directs light from the two fluorescent lamps 2d and 2e in various directions. Diffuse reflection. The reflectance is about 60 to 65%.

【0013】 以上の構造の本考案実施例は、例えば図2に示すように、塗装ラインなどの壁 20に設けた凹部21に嵌め込まれ、その壁20にフランジ11によって固定さ れる。この装着状態で器具本体1の下側の3本の蛍光ランプ2a,2b,2cか らの放射光は、集光用反射笠3によって前方斜め下方に集光されるので、これら の蛍光ランプ2a,2b,2cによって、図に示す領域A1 が高照度で照明され る。従って、作業対象である被照射体Wの廻りは明るくなって、作業性が向上す る。また、上方の2本の蛍光ランプ2d,2eからの光は、拡散用反射笠4によ って種々の方向に散乱するので、先の3本の蛍光ランプ2a,2b,2cでは照 明できない領域A2 も照明することが可能で、これによって、全体的な環境性が 向上する。In the embodiment of the present invention having the above structure, for example, as shown in FIG. 2, it is fitted into a recess 21 provided in a wall 20 such as a painting line, and is fixed to the wall 20 by a flange 11. In this mounted state, the radiated light from the three fluorescent lamps 2a, 2b, 2c on the lower side of the instrument body 1 is condensed obliquely downward and forward by the condensing reflection shade 3, so these fluorescent lamps 2a , 2b, 2c illuminate the area A1 shown in the figure with high illuminance. Therefore, the area around the irradiated object W that is the work target becomes brighter, and the workability is improved. Further, the lights from the upper two fluorescent lamps 2d and 2e are scattered in various directions by the diffusing reflection shade 4, so that the above three fluorescent lamps 2a, 2b and 2c cannot illuminate them. Area A2 can also be illuminated, which improves the overall environmental quality.

【0014】 なお、以上の実施例では説明を省略したが、器具設置場所が塗装ラインなどで 防爆仕様等が義務付けられている場合には、それらの仕様に適合した構造を採用 することは勿論である。Although not described in the above embodiments, if explosion-proof specifications, etc. are obligatory at the equipment installation site such as a painting line, it is of course possible to adopt a structure conforming to those specifications. is there.

【0015】 また、以上の実施例では、照明器具の蛍光ランプの本数を5本とした場合の例 について説明したが、これに限定されることなく、そのランプ本数は、器具設置 場所の照明条件などを考慮して適宜に選定すればよい。Further, in the above embodiment, an example in which the number of fluorescent lamps of the lighting fixture is set to 5 has been described, but the number of lamps is not limited to this, and the number of the lamps depends on the lighting condition of the fixture installation place. It may be appropriately selected in consideration of the above.

【0016】 さらに、集光用反射笠としては、図1に示した形状のほか、例えば凹面あるい は楕円面などを利用した他の形状の反射笠等であってもよい。要するに、この反 射笠は集光性があれば、その形状・構造は特に限定されない。Further, as the condensing reflector, other than the shape shown in FIG. 1, for example, a concavity or an ellipsoidal shape may be used. In short, the shape and structure of this reflecting shade is not particularly limited as long as it has a light collecting property.

【0017】 さらにまた、本考案の照明器具は、塗装ラインのほか、一般的な工場設備ある いは展示場などの各種照明に適用可能であることは勿論である。Furthermore, it goes without saying that the lighting equipment of the present invention can be applied to various lightings such as a general factory facility or an exhibition hall, in addition to a painting line.

【考案の効果】[Effect of device]

以上説明したように、本考案によれば、複数本の直管型光源が配列される器具 に、集光用と散乱用の2種の反射笠を設けたので、特定の領域を高照度で照明で きる上に、全体的な照明の均整度も確保できる。これによって照明すべき空間の 環境性および作業性が向上する。しかも、そのような照明効果を得るにあたり、 従来では照明器具の設置個数を多くすることで対処していたが、その必要がなく なる結果、照明設備のイニシャルコストおよびランニングコストの低減化をはか ることができる。 As described above, according to the present invention, since two types of reflectors for collecting light and for scattering are provided in a device in which a plurality of straight-tube type light sources are arranged, a specific area can be illuminated with high illuminance. In addition to being able to illuminate, it is possible to ensure the uniformity of overall illumination. This improves the environment and workability of the space to be illuminated. Moreover, in order to obtain such a lighting effect, in the past, it was dealt with by increasing the number of lighting fixtures installed, but as a result of eliminating the need, it is possible to reduce the initial cost and running cost of the lighting equipment. You can
