DE19816982A1 - Transparent plate for advertising display - Google Patents

Abstract

The plate (1) has letters (4) and/or graphics/images on its front side and self-luminous fluorescent layer (5) on its rear side (3). The fluorescent layer transforms short wave electromagnetic radiation especially UV radiation into visible light. Behind the plate at least one radiation source is arranged as a tubular fluorescent lamp without any fluorescent layer in its interior. The fluorescent substance of the fluorescent layer is material capable of luminescence.

Description

The invention relates to a translucent pane for advertising purposes with writing and / or Graphics / image components.

It is known to be provided with translucent advertising Backlights to illuminate the Increase advertising effectiveness. For this is the translucent pane on the front of a Box in which one or more lights, especially fluorescent lamps. The the disc illuminating radiation is here within the Fluorescent tube generated, so that it is technically complex is a reasonably uniform lighting of the Reach the disc on the back.

The object of the invention is a translucent To create disc of the type mentioned, which at simple design and manufacture a uniform Illumination achieved with high advertising effectiveness.  

This object is achieved in that the back of the pane is self-illuminating In particular, it has a phosphor layer is coated, the short-wave electromagnetic Radiation especially ultraviolet radiation in converts visible light.

Since the disc itself generates the visible radiation, becomes a much more intense visual impression and thus achieving high advertising effectiveness. About that in addition, the dimensions can be kept smaller and a high energy yield is achieved.

It is useful if behind the window at least one radiation source with a short wave electromagnetic radiation in particular Ultraviolet radiation arranged. Alternatively, however the radiation source can also be arranged further away, especially on reflective surfaces The back of the pane.

A particularly simple construction is achieved if the radiation source (s) from at least one Fluorescent lamp is formed, the none Have phosphor layer. But there are also others Radiation sources generating ultraviolet radiation applicable.

It is preferably proposed that the phosphor Phosphor layer is a substance capable of luminescence. A particularly high advertising effectiveness is achieved if the one on the disc, especially on the back Writing and / or graphics in whole or in part Phosphor exists.

It is preferably proposed that the  Fluorescent layer on and / or in the back of the Front and / or inside the disc. Also can the phosphor layer through a translucent Protective layer must be covered.

An embodiment of the invention is in the Drawing shown in perspective and is in following described in more detail.

A tarpaulin or curved disc 1 made of translucent material, in particular made of glass or a plastic, such as. B. Acrylic has on or in its front 2 and / or back 3 a font 4 and / or graphics, which are particularly useful for advertising purposes or other purposes that make people aware, such as. B. is used in traffic or to indicate dangers.

The back 3 of the pane 1 is coated with a phosphor layer 5 which has a substance capable of luminescence, ie short-wave electromagnetic radiation, such as UV light, is absorbed and converted into photons. The rear side of the pane 1 is irradiated by short-wave electromagnetic radiation, in particular UV radiation. The radiation source can be a tubular "fluorescent lamp", the inner wall of which has no fluorescent material. However, any other source of short-wave electromagnetic radiation can also be used.

In the exemplary embodiment, the phosphor layer is arranged on the rear side 3 and is preferably covered with a transparent protective layer. The phosphor layer 5 can, however, also be arranged on the front side 2 , in turn being covered with a protective layer 6 or a protective plate.

Furthermore, in addition or as an alternative, the phosphor layer 5 can also be arranged inside the pane 3 , in particular in that the pane is constructed in multiple layers. Furthermore, in a further exemplary embodiment, the font 4 and / or the graphic has phosphor, the font and / or the graphic being / are arranged on the front and / or on the rear and / or inside the pane 1 .

Claims (7)

1. Translucent pane ( 1 ) for advertising purposes with writing ( 4 ) and / or graphic / picture components, characterized in that the rear pane ( 3 ) has a self-illuminating phosphor layer ( 5 ), in particular coated with it, the short-wave electromagnetic radiation, in particular ultraviolet radiation converted into visible light. 2. Disc according to claim 1, characterized characterized that behind the disc at least one radiation source with a short wave electromagnetic radiation in particular Ultraviolet radiation is arranged. 3. Disc according to claim 1 or 2, characterized characterized in that the radiation source (s) is formed by at least one fluorescent lamp, that have no phosphor layer. 4. Disc according to one of the preceding claims, characterized in that the phosphor of the phosphor layer ( 5 ) is a substance capable of luminescence. 5. Disc according to one of the preceding claims, characterized in that the writing ( 4 ) and / or graphics located on the disc ( 1 ) in particular on the back consists entirely or partially of phosphor. 6. Disc according to one of the preceding claims, characterized in that the phosphor layer ( 5 ) on and / or in the back ( 3 ) of the front ( 2 ) and / or inside the disc ( 1 ). 7. Disc according to one of the preceding claims, characterized in that the phosphor layer ( 5 ) is covered by a translucent protective layer ( 6 ).
