本発明は、例えば複数の配光パターンを選択的にあるい
は連続的に、手動あるいは遠隔操作によっテ変化させる
ことができる照明装置に関スル。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a lighting device in which, for example, a plurality of light distribution patterns can be changed selectively or continuously by manual or remote control.
複数の配光パターンを切替えることのできる照明装置と
しては、例えば自動車のヘッドライトなどに見られるが
、これは２つの光源と、それぞれの光源に対応して設け
られた反射鏡とにより異なる配光パターンを持たせるも
ので、配光の切替えは光源を選択することによ“るもの
でゐり。An example of a lighting device that can switch between multiple light distribution patterns can be found in car headlights, which use two light sources and reflectors installed to correspond to each light source to create different light distribution patterns. It has a pattern, and the light distribution can be changed by selecting the light source.
ところが、かかる照明装置に＃いては、配光パターンの
数だけ光源を必要とするので、配光パターンの数を増や
すと不経済であり、使用の仕方によってはそれぞれの光
源の寿命番ζ差が生じ、光源の保守交換作業がめんどう
である。また、当然ながら複数の配光パターンからの選
択であって、中間的な配光パターンが得られないといっ
た欠点がある。However, such a lighting device requires as many light sources as there are light distribution patterns, so increasing the number of light distribution patterns is uneconomical, and depending on how it is used, the difference in the lifespan of each light source may increase. This causes troublesome maintenance and replacement work for the light source. Furthermore, as a matter of course, selection is made from a plurality of light distribution patterns, and there is a drawback that an intermediate light distribution pattern cannot be obtained.
また、異なる照明装置として、光源が１つで、その光源
に対応する反射板やルーバなどを可動させる方式のもの
がある。かかる照明装置は、前述のような問題もなく、
また配光パターンも可動の範囲内で連続的に変化させる
ことが可能であるが、上記反射板やルーバなどの光制御
手段は大形であって、これを可動させる機構は頑丈なも
のでなくてはならず、高価なものになってしまう。また
配光パターンを手動でなく自動操作あるいは遠隔操作を
しようとすると、その駆動装置は大形なものとならざる
を得ない。Further, as a different lighting device, there is a type that has one light source and moves a reflector, louver, etc. that corresponds to the light source. Such lighting devices do not have the problems mentioned above,
It is also possible to change the light distribution pattern continuously within the movable range, but the light control means such as the reflector and louver are large and the mechanism that moves them is not sturdy. However, it becomes expensive. Furthermore, if the light distribution pattern is to be controlled automatically or remotely rather than manually, the driving device must be large.
本発明は上記の点に鑑みてなされたもので、その目的と
するところは、配光パターン等の照明特性の変更が容易
で、しかも小形で安価な照明装置を提供するにある。The present invention has been made in view of the above points, and an object thereof is to provide an illumination device that is small in size and inexpensive, and in which illumination characteristics such as a light distribution pattern can be easily changed.

ている。1 and 2 show an embodiment of the present invention. In the figure, 1 is a condensing type incandescent lamp, in which a filament 3 is disposed approximately at the center of the pulp 2, and a bulb 2 is provided with a filament 3. A reflective film 4 is formed on a portion of the inner surface, and light is irradiated from the window 5 where the reflective film 4 is not formed. Reference numeral 7 denotes a condenser lens placed in front of the window 5 of the incandescent lamp 1, so that the light condensed by the lens 7 is focused near a small movable mirror 8 placed behind the lens 7. It is located in 9
is a reflecting plate formed into a desired curved surface, and is a mirror 8
The design is such that the light reflected by the beam enters a part of it, and the light that is further reflected there illuminates the intended target.

は前方に拡がる。The movable mirror 8 is configured to be rotatable around an axis 10, and when the angle is as shown in FIG. The curvature of the reflecting plate 9 is large, and the received light is focused in a nearly parallel shape and illuminates the front surface. When the movable mirror 8 is moved to the angle shown in FIG.
Since it is formed from a flat plate into a slightly convex shape, the reflected light spreads forward.

の場合には配光の変化は段階的となる。In the above embodiment, the reflecting plate 9 having partially different curvatures was used as the light control means selected by the movable mirror 8.
This may be a double-acting reflector with different focal points. In that case, the change in light distribution will be gradual.

Furthermore, variable color can also be achieved by including optical filters in the selected path. Also, small size is possible! The v1 machine m may be of any type, and may be moved manually or by a motor. and,
Since the movable mechanism is extremely small and lightweight, it can be easily realized with a simple @ structure using electromagnetism.

変化を可能にすると云った付加的効果もある。As described above, the present invention focuses light condensed by a condensing system such as a condensing lens on a movable mirror, and by moving the movable mirror, the illumination characteristics such as the light distribution pattern and color tone are controlled by the light control means. can be changed selectively or continuously, so when changing the desired illumination characteristics, the only movable part is the movable mirror, and since the movable mirror controls the focused light, its configuration is simple and small. Furthermore, since the energy required to move the movable mirror is small, it has the additional effect of allowing the illumination characteristics to be changed at the same speed, especially when automated.
