DE202006018664U1 - Optical information protection for airplanes, stairways steps of e.g. humid rooms, has fiber-optic cables and zero-current light supply at transparent plastic component, - Google Patents

Abstract

Optical information protection has fiber-optic cables and zero-current light supply for the light emission (4) at a transparent plastic component, whereby the source of light and the positioning of the source of light are arbitrary. This is suitable for both visible range and the non-visible range of light as a warning notice in form of a light strip.

Description

technical environment

current Warning and signaling devices in the optical field work today with LEDs. For this is a transformer, o. Ä. and a power supply needed.

In spite of the high life expectancy of the LED can lead to failures, which then under certain circumstances generate a high repair effort. (Dashboard in the car)

in the Public area Paths, entrance areas of stations or shopping malls, as well as in the area where moisture or Do not get wet Preventing moisture plays a big role.

State of technology

According to the state of the art, for example, according to the utility model DE 200 06 883 U1 from 23.11.2000 in aircraft plastic rails embedded in the ground, which in turn are illuminated by LEDs. Similarly, stairs in cinemas, parking garages or other buildings are marked. Again, the problem of possible failure and costly maintenance due to the disturbance caused by moisture is given.

A Further development was the direct introduction of the LEDs into the plastic. The maintenance increased and the electrical supply remained vulnerable.

The task

The The task is to maintain the lighting device, insensitive to moisture, gas and make water.

Technical solution

My Invention preferably uses plastic parts of transparent Material (such as acrylic glass) as light guide to the light in the environment leave. The supply of plastic moldings via optical fibers (LWL), which in turn are supplied decentrally with energy (light). to reinforcement the fluorescent effect, fluorescent material can be used.

The Mounting can be on the floor, in the floor, on the wall or ceiling respectively.

Short description of drawings

drawing 1 represents the possibility is the light from a distant room to the light exit opening transport. For example, here are two walls drawn, it can But they are also floors or even other buildings.

example 2 shows the simple solution on stairs with the different possibilities.

example 3 can be on buses, trains or other means of transport as a boarding aid serve, at the same time by another color (red) use (signalizing) restrict.

Examples of the optimal use

Underwater levels in an amusement park with swimming pool and sauna area. You could do that here Light bar (plastic molding) to adjust the stairs, the Light supply via fiber-optic cable out of a dry room into the water. All advantages are given here: sure Insensitive to water and easy to maintain.

direction signaling in a parking garage. You can see the light bar in the floor, on the wall or the ceiling. By different colors you can signal a control system. The light supply can be decentralized again take place, i. in the case of a defect of the light supply must no roadway be blocked or the like, but you can simply replace the light source from an adjoining room.

entry signals in public Transport. With changing curb heights can be an optical device Reduce danger of falling. In addition, can the "entry stream" through color change or flashing light.

Escape route signaling in airplanes or other mass transit vehicles (like ships). Usually There is a light bar in the passage area, which is for the persons to give an orientation guide. By replacing the usual today light strips in the ground would in addition to the weight in addition reduce the maintenance effort.

In Parking garages, Cinemas and hotels leaves a similar one Plant for the escape route signaling easily retrofitted to the walls, in Install floor or ceilings. The maintenance is limited on the regular change the filament.

to Lighting of fittings. The light source is not directly in the fitting is integrated but placed outside. The optical fibers supply the fittings with light. Here is the ease of maintenance in the foreground.

Because of the gas-tightness is such a escape route signaling system especially for hazardous building or parts of it.

Three embodiments of the invention will be described with reference to 1 to 3 explained in more detail.

1

Example of a wall penetration and the emission possibilities

At ( 1 ) the light source is adapted. The light is transmitted through a wall ( 2 ) over a large ( 3 ) Route transported by means of a light guide.

The light emission ( 4 ) can meet the needs either as a narrow exit ( 4 ) at a thin material thickness ( 5 ) (t> 5) or for other needs ( 6 ) with a wide outlet.

2

Example of realization on steps, or walls (these can also under water or in explosive areas)

Acrylic glass rods ( 7 ) can be cut into a milled groove ( 8th ) are admitted. The luminous elements are transmitted via the optical fiber ( 9 ) from a light box ( 10 ) via a light adaptation ( 1 ) supplied with light. This box can be mounted in a place that makes the easy maintenance of the light sources possible.

Further examples of attachment are the superior ( 11 ) Variant or the below ( 12 ).

This Example leaves also apply to a dashboard of a vehicle because you do not forcibly integrate the lightbox into the dashboard got to.

3

In the entry area inside and outside of vehicles ( 13 ) or inside the vehicles ( 14 ) embedded in the ground or the wall, these bulbs can be arranged as a warning and control system.

Claims (1)

Protection claim for optical information with the help of fiber optics and de-energized Light supply of the light exit on a transparent plastic (acrylic) part, wherein the light source and the positioning of the light source arbitrary is. This affects both the visible and the invisible Area of light. after 1 as a warning in the form of a light bar in steps, especially in damp rooms, swimming pools and Saunas. to 1 as a control system generally in entrance areas of heavily frequented facilities (buildings), particularly suitable there, where with moisture or moisture is to be expected. after 1 as a guidance system in public transport. This can be embedded in the floor or wall, as well as the doors in the outdoor area mark. after 1 for the light supply of passenger guidance systems in means of transport and function rooms. to 1 for the Light supply of fittings for vehicles of the street, Water and air traffic after 1 for the light supply of weather-insensitive Billboards, signs or traffic signs. to 1 for the Light supply an escape route guidance system in explosion-endangered buildings or parts of it.
