本考案は反射カサで配光を制御する方式の照明器具の改
良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a lighting fixture that controls light distribution using a reflective umbrella.
従来たとえば非常用に使用されるこの種の照明器具では
法律で定められた必要照度を広範囲に得るために透明は
電球と鏡面の反射カサとを組合せて配光を制御していた
が、それでも使用状態では照明器具直下付近は電球から
の直射照度だけでも必要照度より大幅に高くなることが
多く、その分を周囲に分配して必要照度が得られる範囲
を拡大することが望まれた。Conventionally, for example, in this type of lighting equipment used for emergency purposes, in order to obtain the required illuminance required by law over a wide area, the light distribution was controlled using a combination of transparent light bulbs and mirror reflective casings. In the current situation, the direct illuminance directly under the lighting equipment is often much higher than the required illuminance even from the light bulb, so it was desirable to expand the area where the necessary illuminance could be obtained by distributing the illuminance to the surrounding area.
本考案はこれを達成できる機能を有する照明器具を提供
するため、電球から直下付近への直射光を効率よく制御
して他方向へ再配分可能とすることを目的とし、外管が
透明な電球のフィラメントからの光を電球のフィラメン
ト方向以外およびランプベース部以外の方向に反射する
補助反射板を電球に取付けたことを特徴とするものであ
る。In order to provide a lighting device that has the function of achieving this, the present invention aims to efficiently control the direct light from the light bulb to the area directly below it and redistribute it to other directions. The lamp is characterized in that an auxiliary reflector is attached to the light bulb to reflect light from the filament in a direction other than the filament direction of the light bulb and in a direction other than the lamp base.
以下本考案の一実施例につき図面とともに詳述すると、
1は本考案の照明器具を取付けている天井、2はこの天
井に取付けられた器具本体で、その中央下面にはランプ
ソケット3が取付けられ、これには透明な電球4が螺着
されている。An embodiment of the present invention will be described below in detail with reference to the drawings.
1 is the ceiling on which the lighting equipment of the present invention is installed; 2 is the equipment body installed on the ceiling; a lamp socket 3 is installed on the lower center surface of the equipment, and a transparent light bulb 4 is screwed into this. .
電球4は下半分を球状になし上半部を円筒状とした外管
41と、その上半部上部に固着したランプベース42と
、外管下半部の球状中心部に設けたフィラメント43と
からなり、かつ電球4の周囲には電球4からの光を必要
な方向に反射するための反射笠5が距離を距てて設けら
れている。The light bulb 4 includes an outer tube 41 whose lower half is spherical and whose upper half is cylindrical, a lamp base 42 fixed to the top of the upper half, and a filament 43 provided at the spherical center of the lower half of the outer tube. A reflective shade 5 is provided around the light bulb 4 at a distance to reflect the light from the light bulb 4 in the required direction.
電球4の下端44付近には補助反射板6が取付金具7に
より電球4に取付けられている。An auxiliary reflecting plate 6 is attached to the light bulb 4 near the lower end 44 of the light bulb 4 with a mounting bracket 7.
補助反射板6の内面61は鏡面で、その形状は全周縁6
2が電球の外管41に接し、内面各部の法線N−N′は
電球4のフィラメント43より下で電球を横切るととも
にランプベース42部と交わらないように形成されてい
る。The inner surface 61 of the auxiliary reflector 6 is a mirror surface, and its shape is similar to that of the entire periphery 6.
2 is in contact with the outer bulb 41 of the light bulb, and the normal line N-N' of each part of the inner surface is formed so that it crosses the light bulb below the filament 43 of the light bulb 4 and does not intersect with the lamp base 42 part.
本考案は上述のように構成されているから、一般的な透

収しやすいフィラメント43およびランプベース42部
方向以外の方向に反射され、ランプ4の透明な外管41
を通り抜けて反射笠5に入射し、必要な方向に配分され
ることになり、それだけ効果が良くなる。Since the present invention is constructed as described above, the light emitted from the filament 43 and incident on the inner surface 61 of the auxiliary reflector is reflected by the filament, which easily absorbs the light, while using a general transparent outer bulb light bulb. 43 and the lamp base 42, the transparent outer tube 41 of the lamp 4
The light passes through and enters the reflective shade 5, where it is distributed in the necessary direction, which improves the effect accordingly.
また補助反射板6はその全周縁62で電球に接触してい
るからその内面61へのほこり等の侵入が防止され、効
率のよい鏡面が長年月に亙って維持される。Further, since the auxiliary reflector plate 6 is in contact with the light bulb with its entire periphery 62, dust and the like are prevented from entering its inner surface 61, and an efficient mirror surface is maintained for many years.
さらに必要により補助反射板6の電球をおおう位置を変
更することも可能で、これにより照明器具の配光を変更
できるなどその効果は大きい。Furthermore, if necessary, it is also possible to change the position of the auxiliary reflector 6 covering the light bulb, which has great effects such as changing the light distribution of the lighting equipment.
