Lighting fixtures.

The innovation relates to a lighting fixture with a light source arranged within an essentially light-impermeable screen provided with one or more light outlet openings, and aims the achievement of special optical effects.

In advertising, especially in shop window decorations, more and more optical effects are used today, which are intended to attract and banish the eye of the beholder in order to influence the intention to buy to evoke. It is known, for example, in shop window decorations with strong rays of light or also to work with mirror prisms or the like, taking advantage of the strong contrasts between glaring light and darkness.

The task of the air conditioning is to provide a device, nit what nan such optical effects on quite effective Wise can cause and on the other hand is not very expensive to manufacture and operate.

This task is solved by the innovation in one Lighting fixture of the type described above, characterized in that an expediently of an electric motor within the screen driven turntable is arranged, the at least one of the rays of the light source to the / the light output

entry openings towards reflecting mirror. By the rotation of the turntable will be the one on ih; .. arranged Light thrown into the mirror is continuously reflected in other directions within the casing in certain positions of the mirror to the exit openings from this, and generated on the wall or ceiling of the room concerned moves at the speed of the Turntable moving light effects. Of course, these reflected light rays change constantly because they are one after the other exit through the various openings of the lampshade and on the other hand the angle of incidence and the angle of reflection through the permanent Change the position of the mirror (s) in relation to the light source. The light exit openings are of course familiar be provided both in the side walls of the screen and in the ceiling of the same, creating the diversity the individual lighting effects is increased. For example, one can use a A multitude of my holes in the ceiling imitate a whole starry sky, which slowly, i.e. accordingly the speed of rotation of the table. This rotation speed is of course not appropriate too high, because too rapid a change in the individual reflexes on the eye is tiring and confusing will work. Rather, if the electric motor used has too high a speed, a suitable one can be used Zv / ischenschalten the gear to achieve a speed of the turntable which is expediently of the order of magnitude of l / min. - In its basic structure, there is the lighting fixture, apart from the lamp and the Turntable, the simplest way of doing this, is a wire frame, over which a suitable screen with the light exit openings can be pushed over. It depends on the fact that the device, in particular its interior, i.e. before especially the turntable with the mirrors arranged on it

as well as the Lajnue are easily accessible.

In addition to being used in advertising, in particular in shop window advertising, there are such lighting fixtures also as toys in question, since one children with such devices that a movement of lights and that the Make imitation of the stars possible, very enjoyable. Finally, such devices are also used as anti-theft devices conceivable, because you can set up and operate them in an abandoned apartment and so to the outside world Awaken the sensation as if the apartment was not abandoned, but rather constantly in motion.

Un to bundle the light enough and an unnecessary one To avoid scattering and thus a loss of light energy, the light source is preferably through a Cover must be protected against direct radiation failure through the light exit openings. It comes of course To achieve the special optical effects, it is important that all light is thrown onto the mirror if possible and is reflected by these, because this is the only way to ensure the movement of the rays,

As already mentioned, the lampshade can of course with a large number of light exit openings be provided. In order to be able to achieve new effects again and again, one becomes the light exit openings advantageously form easily closable to provide sometimes one, then the other opening for the light or to produce a wide variety of combinations. It has proven to be particularly useful pointed out to arrange a second screen, which can be pushed over the first screen and thereby a Part of the openings of the first screen closes,

while leaving others open. The most diverse variations are undoubtedly possible here, which do not necessarily have to be described here. However, care should always be taken to ensure that sufficient air circulation is possible because the heat generated by the light source in a largely closed screen is very high and could easily lead to damage. In order to ensure this air circulation, especially when a second screen is pushed over the first, the second screen is vortexed with spacers so that there is always a sufficient distance between the first and the second screen and thus sufficient air movement.

Further, the "firing, according to one particularly advantageous feature is provided as ^Q / the mirrors are arranged in position to the light source and the openings easily adjustable to the rotary table of the. This easily adjustable arrangement can take place, for example, by a foot or some other holder that is screwed onto the turntable and pegeη the mirror has a rotary joint, for example a ball joint, which can be adjusted by simple handling. In this way, the number of effects to be achieved is further increased, since nan can, for example, arrange several mirrors in a wide variety of positions on a turntable, which then cause a multitude of light effects one after the other with a single revolution of the table. It can be seen that it is useful for the easy adjustability of the mirror, as indicated above, to create easy access to the interior of the lighting fixture.

Finally, it can also be easily detectable and expedient, in addition to the presentation of the table

to make the screen rotatable in order to achieve an even greater number of light effects. However, the technical and constructive effort required for this can easily become too great, so that normally only one device with a rotatable table carrying the mirrors is provided . earth.

The innovation will now be explained in more detail with reference to the embodiment shown in the schematic drawing. Show it

The lighting fixture has a wire frame 1, which in the example shown has the basic shape of a cuboid, but of course any other shape as well may have a geometric shape.

Under the lamp is attached to the bottom 32 of the screen, a turntable 8, which is driven by a not visible here, arranged in a housing 9 electric motor. In order to enable the turntable 8 to rotate slowly enough, a gear mechanism is interposed between this and the Ε-motor, so that the turntable 8 expediently rotates at approximately one revolution per minute.

On the turntable 3 there are one or more τ j iegel IC which have a support foot 11, which allows a slight angle adjustment of the mirror. This can be done, for example, in a known manner by a rotary or Ku-eleelenk, ^ o aa? the mirrors can be changed quickly with regard to the angle of incidence and reflection of the light

It will be clear to any person skilled in the art that a large number of different types of light can be produced by various variations of the covering and opening of the light passage openings.

The mode of operation of the lighting fixture according to the invention is that the light from the bulb provided inside the cover 6 is bundled thanks to the cover 6 and thrown down onto the mirror 10 , which, depending on its setting, reflect it in the various directions. The directions of reflection are continuously changed by turning the turntable =? ^c . as a result of being driven by the electric motor. The rotation is very slow, for example with 1 / irin.
