Abstract

The invention substantially relates to a device for visualizing at least one danger zone by means of lighting technology, wherein a projection system is connected by way of at least one light transport element to at least one light emission unit, which is arranged such that direct projection of a danger zone marking or parts thereof into a human eye is avoided, and the human eye perceives the danger zone marking only indirectly via a projection surface. In the device according to the invention, the projection system can be attached substantially without vibrations, and a projection of a danger marking can be made without glare without moving parts, which would be susceptible to wear. Said device is particularly suited for vehicles, such as trains.

description

Device for photometric visualization of danger zones, especially in vehicles

The invention relates to a device for the optical marking of a potential danger zone, in particular in vehicles. From laid-open on 23/04/2009 German Laid ¬ specification DE 10 2007 048 831 Al an apparatus for opti ¬ rule mark of a potential danger area of a machine, in particular an automatically operating window cleaner is known, said machine is associated with such a laser module so that its light beam is independent of the spatial orientation of the machine by static or dynamic deflection about a parallel to gravity pointing un ¬ th axis movable and thereby marking of the outer limits of the danger zone is made possible.

By the gimbal mount of the laser in order to depart with the La ¬ serstrahl the edge of the danger zone, moving parts are required in the aforementioned prior art, the recycle especially when used in vehicles often problems me because, for example. By vibrations a destabilized - sation or decalibration or wear occur or expensive bearings are required. In addition, working in the projection area people can be blinded by the light source or the light intensity must be limited because of this, which may result in daylight indistinct markings.

The object underlying the invention is now to provide is in ¬ a device for photometric visualization of danger zones, in which the abovementioned disadvantages are avoided.

This object is solved by the features of Pa ¬ tentanspruchs. 1 The further claims relate to advantageous configurations of the invention.

The invention relates generally to a device for lighting at least one visualization danger zone, wherein one projection device through at least one

Is light transport element is connected with at least one Lichtaustrittsein ¬ uniform, which is arranged such that a di ¬ rect projection of a danger zone marking or parts thereof, in a human eye is avoided and the human Liehe eye the danger zone marking perceives only indirectly via a screen. This device is particularly for vehicles, such as. Trains suitable because no destabilization or de-calibration or mechanical wear occur in follow Erschüt ¬ esterification. In the luminosity passengers need not be limited and it can be produced without the example even with Ta ¬ Natural Daylight distinct markers. Dazzled.

The invention with reference to an embodiment shown in the drawing will be further explained. Here shows

Figure 1 is a schematic diagram for explaining the invention,

Figure 2 is a diagram of a first application example and

Figure 3 is a diagram of a second application example. In figure 1 a device for photometric visualization of a danger zone is shown

wherein a projection device P is connected via an optical transport element LT with a light emission unit LA.

By points below the projection device P and the light transport element LT, it is indicated that, for example for projection of a danger zone. Facilities also several projection P with one or even a plurality of light transport elements LT and light exit units LA

are . Contains the light transport element LT, similar to a periscope, at least one light pipe having at least one steering mirror To ¬ U and / or an optical waveguide.

contains the projection unit P, a controller CTRL, a light source LS, a modulation means M and a lens LI. As the light source LS strong lamps, LED's or laser diodes are suitable depending on the application.

In a first embodiment, in the projec ¬ onseinheit P, a modulation M, that is comparable produced by a slide projector, light with the image content of the danger of marking, and in this case the light-emitting unit LA consists only of an ordinary spherical lens L takes place such.

In a further embodiment variant, only light is generated with no image content in the projective onseinheit and by

Light emission unit LA which produces the shape of the projection 1 of the danger of marking or parts by a correspondingly shaped lens L, for example a cylindrical lens for generating a light beam, and / or a correspondingly shaped reflector R.

In a particularly simple embodiment, the function of the above-mentioned deflection mirror U is taken over by the reflector R or it is not a deflecting mirror U upstream hands.

The controller CTRL typically receives an external activated vierungs / deactivation signal I and possibly control parameters CP and may, for example alongside the light source LS., The modulation means M via a corresponding signal CM to control. In this way, a temporal modulation is performed in the projection unit P optional such that the color and / or Intensi ¬ ty and / or flashing frequency and / or the size of the projection 1 a danger zone marking are variable over time.

The inventive device is achieved that the projection device can be brought substantially vibration free on and can be carried out a projection of a hazard marking without any moving parts and therefore susceptible to wear glare.

The glare is here by a light guide, ie, for example., Reached at foot or in other areas where the head of a person usually is not.

In Figure 2, the application of the device to a train door to be closed outlines. A projection unit P were here ¬ at below the door - which they usually still slightly elevated to the platform - mounted; etc. glare from La ¬ ser is thus almost completely for For at this level ¬ close. In addition to a beeping, the soil is, for example, marked with semi-circles in front of the door area. In this way, the warning insistent and the actual danger zone is more apparent. Also, at the risk for hearing impaired clearly or at all only gratitude.

Figure 3 shows the application in connection at one aircraft engine. The aircraft is abge ¬ forms in the so-called. Push-back phase. Ie a tug, the aircraft pushes away from the passenger bridge. At that moment the engines are short from the start, so that can cause danger by sucking in surrounding guests (see person on baggage tractors right). For the danger zone shapes are projected onto the bottom of the runway because of being sucked in and exhaust plume are not visible. By transformation or scaling the projection can further the current danger zone in accordance with

activity of the turbine can be varied.
