luminaire for fluorescent lamps

The invention relates to a lamp for fluorescent material Lamps with an elongated lamp housing to accommodate the equipment and facilities required to operate the fluorescent lamps, with the luminaire housing has at least one opening for cable entry is provided. Lights of this known type are often used in factories, offices and sales rooms and the like as so-called light bands twist

det, by having several lights with their front sides butting directly against one another to form an elongated bar be relocated. If the luminaires are mounted on a wall or ceiling »this would have to be done for each individual luminaire A ceiling or wall structure is provided for the credit tape be for the introduction of the electrical cable, which is usually because of the cumbersome effort is avoided. Rather, openings are provided on the front sides of the lights to accommodate the cables to be able to introduce. These cable entries must be under Circumstances sealed aeinfor what purpose gland connections are provided. These gland connections have a certain length, so that they protrude from the actual face of the lamp by a not inconsiderable amount. Prevent these stuffing boxes on the front sides of the lights But, there are lights for creating one so-called light band directly to each other. can be laid, which is not a nice thing for the strip of lights Gives appearance.

There are drawn, connection-stiff sheet steel profile rails, on the underside of which the lights are attached to each other, with the drawn profile rail serves to accommodate the wiring. This proposal 'not only requires a substantial additional effort, but also also increases the construction height of the light strip to a considerable and undesirable extent.

It is now the task of the invention to remedy this situation} what is achieved by the fact that the lamp housing opposite a surface carrying the opening for the cable feed-through is preferred to the side.

In this way it is possible to place the lights directly butting against each other on the front side, because, thanks to the suggestion according to the invention, now the front side incisions τογΙ That both upwards and are open to the front, so that the line cables can be introduced from the front or from the ceiling or from the land.

Surface 2 'can also be provided with two openings, one serving as a cable inlet and the other as a cable outlet. If lights of the designated type are laid in tunnels or galleries, it can happen that they collect dripping or condensation water in the chamber-like tree formed by the incision. The drainage of this water is ensured by the aforementioned inclination of the base surface 4. If lights of this type are not laid as a strip of light, but as individual lights, the chamber-like tree formed by the incision can be closed at the end by a cover 6 by arranging this cover approximately flush with the front end face parts 2 ''. By clamping, Muten This lid can be held in place on the basting side. This cover also has a zone 7 indicated in stripes, the wall thickness of which is kept smaller than the wall thickness of the remaining part of the deekele. The Mose Zone serves as an eruption zone for the extraction and maintenance of a cable inlet or passage. The cover 6 is expediently designed in such a way that in its versohlijiiststellung it delimits a passage opening for the drainage of drip or condensation water with the front rear edge 10 of the incision.

Luminaires with very wide end faces can be provided with two or more rearwardly offset surfaces 2 'and 12 *, the lamp body in each case being drawn forward between these surfaces. However, a single surface can also be arranged that runs through the Ulm front side and is offset to the rear / whereby the luminaire body is then only pulled forward in the band area *
