"Fluorescent letter or similar symbol"

The innovation concerns in particular solid and hollow characters or similar symbols which _fi using fluorescent plastic polymethylacrylate

j or similar material and by the

Influence of daylight or other ultraviolet-containing Light can be stimulated to shine automatically.

■ | Plastic of the type to be used is in the form of clear Plates of several colors on the market. It is also used to a lesser extent for advertising purposes, because it has the property, among other things, of shining fluorescent on its cut edges. For example, this material is occasional to be seen in the form of advertising structures in shop windows; with the help of black light lamps an interesting effect is achieved.

The innovation consists essentially in the fact that the entire front surface of a plate can be made to glow with fluorescent polymethylacrylate if its back is provided with a predominantly "white, firmly adhering" material.

In the fulfillment of the task, letters can easily be made of series-produced panels according to the new design

cut out of fluorescent plastic and with can be completed with little technical and cost-related effort. The optical effect achieved is like this strong that letters after screeding turn into more conspicuous Way to emphasize among others, so that, for example, a particularly high level of effectiveness is achieved. In addition, they are easy to clean, otherwise maintenance-free and free of oxidation and corrosion.

The innovation is explained using the following application examples.

From a plate made of fluorescent polymethyl acrylate a letter is cut out in the desired size and color, and its cut edges are polished » The back of this letter is marked with a white, Coated synthetic resin varnish suitable for the material.

If it is - as another example - a hollow letter illuminated from the inside, this is shown in built in the conventional way. In this case, the innovation is that the previously used, Front and / or side surfaces made from simple, translucent plastic are replaced by such, which consist of fluorescent polymethyl acrylate and are coated on their back. Finally each letter is coated with a special, transparent varnish to maintain fluorescence. With solid letters it can be of interest to intensify the luminosity in well-known Way to illuminate with a mercury vapor lamp.
