DE19817065A1 - Indication lamp, especially rescue symbol lamp - Google Patents

Abstract

The indication lamp has a lamp housing (1) as a carrier for at least one lamp (3) with one or two light exit points (2) opposite one another for rear illumination of the surfaces (6) containing indication or rescue symbols (9). The light exit surfaces possess the same geometry and dimensions at the surfaces for accommodating the symbols. The surface accommodating the indications and rescue symbols is located on a plane or curved transparent carrier disc (4) projecting over them. The disc is mounted in front of the respective light exit surface of the housing and is recognizably greater than the light exit surface

Description

The invention relates to a decorative indicator light, in particular Exit sign light.

The information elements and escape signs are usually on translucent Carrier discs applied, which in the light exit openings of the Luminaire housings are arranged and one or more lamps in the interior the luminaire housing are backlit.

The shape of the light exit surface and the base area of the pictograms or Exit signs are almost identical and the outer shape of the lamp is therefore largely determined by the shape of the light exit surface. The external appearance of both lamp versions is due to the constructive Structure of the lamp determines and is always box-shaped.

The housing is in a further version of information and escape sign luminaires to the side of or above a light guide disc - light is fed into the edge - arranged. Here too, the design is attributed to the assignment of the lamp housing and Embossed base of the information elements and escape signs. Is an exception the recessed ceiling light, in which the housing disappears into the ceiling. By the However, using the light guide disks makes it difficult to produce such lights.

The object of the invention is therefore to find a luminaire construction in which the Shape of the light exit surfaces of the luminaire housing and their assignment to Base area of the information elements and escape signs are not dominant for that Design is and which is also easy to manufacture.

To solve the problem of the invention is known from a person Luminaire housing out, with one or two opposite one another Large light exit areas for backlighting the information elements and Escape sign.

According to the carrier disk of the pictogram in front of the respective Light exit surface - preferably arranged at a distance. Will continue According to the invention, the carrier disk is designed substantially larger than that Light exit opening of the housing, so that the corresponding edge formation Carrier disc can serve as a decorative element.  

If clear transparent material is used, the carrier disc is in the area of Light exit surface of the housing preferably on that facing the housing Side with a highly scattering structure or translucent coating Mistake. As a result, in the area portion of the carrier disk provided for this purpose uniform and sufficiently bright backlighting of the information elements and Escape sign causes.

In addition, the structure or coating causes light to come from within Reflection is caught in the disc and passed on to the outside.

If the carrier disc is now transparent, the area around the and escape sign area clear, while the edge of the carrier disc lights up. This effect can be achieved by faceting the edge of the pane be reinforced.

Practical tests have shown that while maintaining the usual lighting properties of such lights, the formation of the support plate determines the external character of the lamp and thus in a variety of designs makes luminaire variants easily available without changing the Housing is needed.

Additional decorative lighting effects result from the gap between Carrier disc and housing emerging light.

In addition, lighting effects can be achieved when the housing Has light windows for direct lighting of the path.

A particularly appealing version results, for example, if the Carrier disc has an elliptical outer contour and at a distance, for. B. 10 mm an approximately 100,200 mm light exit surface of the housing is arranged.

The carrier disks can be flat or curved.

Information elements and escape signs can be found on the front of the carrier plate be applied directly or optically separated at a distance on a film, so that at appropriate attachment an easy change of content is possible.

The invention is explained by way of example with reference to FIGS. 1 and 2.

The housing 1 has a light exit opening 2 which is backlit by the lamp 3 . The carrier disk 4 is arranged at a distance from the light exit opening by means of fastening elements 8 . This is translucently coated on the side 5 facing the housing. An escape sign 9 is arranged on a thin film in front of the carrier disk 4 . The sign could also be arranged directly on the carrier disk 4 .

The edge 7 of the carrier disk lights up due to the light-guiding effect due to the light introduced by means of the translucent coating.

The carrier disc 4 is significantly larger than the light exit opening 2 and is elliptical.

However, Fig. 2, the same inventive light assembly shown with double-sided light emission by the two light outlet openings 2. Carrier disks 4 are arranged in front of both openings 2 and are fastened by means of the fastening elements 8 and shone through by a common lamp 3 .
