Abstract

A molded frame-light has a frame-type lamp housing and at least one longitudinal light source which is held at two opposite facing positions of the light housing (2). Two lamp base holders (30) are releasably joined to the shaped element (10) and carry at least one lamp fitting (50) for holding one end of the light source.

Description

The present invention relates to a so-called. Profile frame light according to the preamble of claim 1.

Such lights are usually arranged by means of a cable suspension at a certain distance from the ceiling of a room to be illuminated. The housing of the lamp is formed from a plurality of profile elements, which are assembled into a housing frame. Within this frame, a light source is arranged, which emits at least a portion of its light to the bottom.

Since the luminaire housing of the profile frame light described above has no back or bottom side, the light source must be attached directly to the profile frame. For this purpose, constructions are so far known which are relatively expensive and complicate the installation of the lamp.

The present invention is therefore based on the object to provide a way to arrange a light source in the simplest possible way in a profile frame light.

The DE 23 36 418 A1 discloses a luminaire having a housing and an elongated light source, wherein the socket holders of the elongate light source are fixed at two opposite points of the housing. However, this is not a detachable connection.

The DE 44 16 110 A shows a lamp with a mounting rail on which the equipment carrier including socket holder of the light source are mounted by a one-sided entanglement.

The object is achieved by a luminaire having the features of claim 1.

The luminaire according to the invention initially has a frame-shaped luminaire housing consisting of at least one profile element and at least one elongate light source which is held at two opposite positions of the housing. For this purpose, according to the invention serve two socket holders, which are detachably connected to the profile element and each carry at least one lamp socket for holding one end of the light source. The frame holders are designed latchable with the profile element.

The inventive use of the two frame holder allows a very simple and quick installation of the lamp. In particular, the light source can now be easily clipped into the frame-like luminaire housing without having to carry out further assembly steps. That's the way it is, for example no longer necessary to screw holding elements for the light source to the luminaire housing.

Further developments of the invention are the subject of the dependent claims. Thus, the socket holder according to the invention are preferably bent substantially U-shaped, wherein on a first U-leg latching projections / -rücktritte are arranged, which cooperate with corresponding latching recesses / projections of the profile element, and wherein the second U-leg of the socket holder carries the lamp holder , For this purpose, the second U-leg may have a plurality of detent bores with which latching pins located on the lamp socket can be latched.

In addition, a laminating element, which has a laminating plate arranged underneath the lamp holder, can each be arranged on the holder holders. This plate ensures that from the bottom can not be looked at the socket and thus on the led to the socket lighting wiring.

According to a particularly preferred development of the profile-frame luminaire according to the invention, a light-influencing element in the form of a grid arrangement is arranged in front of the light source, as seen in the emission direction, which has a plurality of passage openings provided for light emission. Such latching arrangements are already well known and are used to restrict the light emitted by the light source to a predetermined angular range and thus to avoid glare.

According to the present invention, the latching arrangement may consist of several individual modules, which are joined along the light source to the latching arrangement. Since it must be ensured for photometric reasons that the individual modules are close together, each biasing elements may be provided on the front sides of the grid assembly, which compress the modules in the longitudinal direction. In particular, the biasing elements may also be located on the socket holders.

Another development of the invention is concerned with the design of the grid arrangement. This preferably has a longitudinally extending back reflector, which is intended to reflect a part of the light emitted by the light source against the emission direction. Within the back reflector then the passage openings are arranged, which are intended to the remaining part of the radiated from the light source Let light pass through in the direction of radiation. The back reflector ensures that at least a small part of the light emitted by the light source is thrown upwards in the opposite direction to the main emission direction and thus a supplementary indirect illumination is produced.

To the openings in the rear reflector can also follow in the direction of radiation pot reflectors, which are preferably integrally connected to the rear reflector. This pot reflectors create the impression of a series arrangement of multiple halogen lamps, which gives the lamp a particularly interesting appearance. They may be connected to one another at their edge regions via a connection plate arranged parallel to the light source and have a square or a rectangular light exit opening with a size of preferably approximately 40 mm to 60 mm in diameter.

Overall, a lamp is thus created, which on the one hand has a pleasing appearance and good lighting properties, on the other hand, however, is also very easy to assemble.

The in the FIGS. 1a and 1b illustrated and generally provided with the reference numeral 1 grid frame lamp consists of a frame-shaped lamp housing 2, which is to be attached via a cable suspension to a (not shown) ceiling of the room to be illuminated. The luminaire housing 2 is formed from four profile elements 10, which are cut to fermentation and joined together to form the frame-like structure. The profile elements 10 are extruded aluminum profiles whose structure is described in more detail later.

The suspension of the lamp 1 is carried out by means of four suspension cables 3, which are each to be fixed to the ceiling. At their end remote from the ceiling, the suspension cables 3 each have an anchoring element 4, which is inserted into a suspension groove of the profile elements 10 and thus anchored in the housing 2.

Between the two end faces of the lamp housing 2 extends a lighting arrangement, which consists of two elongated light sources 55 in the form of two gas discharge lamps and on the other from a grid assembly 20, whose structure will be described in more detail later. The attachment of the light sources 55 to the lamp housing 2 by means of two inventive holder holder, which now with reference to the FIGS. 2 to 6 be explained in more detail.

The profile element 10 is designed substantially C-shaped and provided with the socket holder 30, whose design in particular the FIGS. 3 to 5 can be removed, to lock. For this purpose, the profile element 10 in its opening region on two latching recesses 11, 12, in which corresponding latching projections 33, 35 of the socket holder 30 engage. The frame holder 30, which is stamped, for example, spring plate is bent in a U-shape, wherein the locking projections 33, 35 are arranged on a first U-leg 31. Again Presentation in FIG. 5 can be removed, this first U-leg 31 is split fork-shaped in its lower part in two sub-areas 32, the lower ends are bent to two locking lugs 33. The upper locking projection 35, however, is obtained by a punched out of the first U-leg 31. The two lower portions 32 of the first U-leg 31 also have two bent spring tongues 34, whose function will be explained later in more detail.

The second U-leg 36 of the socket holder 30 is provided for holding two lamp holders 50 and has for this purpose a plurality of locking holes 39, in which on the back of the sockets 50 arranged locking pins 51 engage, as in particular the illustration in FIG. 2 can be removed.

Another element, which is arranged next to the two lamp sockets 50 on the socket holder 30, is provided with the reference numeral 40 and in FIG. 6 This consists essentially of a laminating plate 42, from which a latching head 41 extends upwards, which is provided for latching with an inwardly bent projection 37 of the second U-leg 36 of the socket holder. A secure arrangement of the lamination element 40 is further ensured by two provided in the lining plate 42 projections 43, which are supported on the lower edge of the second U-leg 36 of the socket holder 30.

As the representations in the Figures 2 . 3 and 4 can be removed, the laminating plate 42 is then disposed below the lamp sockets 50 and prevents that can be seen from below on the lamp sockets 50 and thus on the led to the lamps luminaire wiring.

The unit consisting of the holder holder 30, the lamination element 40 and the two lampholders 50 can then be clipped onto the profile element 10 as a whole, the corresponding latching projections 33 and 35 of the holder holder 30 engaging in the profile recesses 11 and 12 of the profile element 10. As a result, a mounting of the essential - responsible for the lighting - components of the light on the profile frame allows in a simple manner.

As already related to the FIGS. 1a and 1b has been mentioned, the luminaire according to the invention a - in the emission direction - arranged in front of the light sources 55 latching arrangement 20 to the emitted light down restrict certain angular ranges. The design of this locking arrangement 20 will now be described in more detail with reference to FIG. 7 and FIG. 10 be explained.

As can be seen from both representations, the latching arrangement 20 initially consists of a cross-section approximately semicircular-shaped rear reflector 21, which surrounds the lamps in the mounting position at least partially and causes at least a small proportion of the light emitted by the lamps 55 light reflected to the top becomes. The luminaire according to the invention thus achieves both direct and indirect illumination.

Within the return reflector 21 a plurality of passage openings 23 are arranged, which are intended to allow light to pass in the emission direction. Each of these passage openings 23 is followed by a pot-shaped reflector 22, which may, for example, have a round or rectangular light exit opening with a size of approximately 40 mm to 60 mm in diameter. The juxtaposed pot reflectors 22 give the impression of a series arrangement of several halogen lamps, whereby the lamp is given a special, visually interesting appearance. At their edge regions, the pot reflectors 22 are connected to one another via a connection plate 24 arranged parallel to the lamps 55.

The individual elements of the reflector assembly 20, so the back reflector 21, the pot reflectors 22 and the connecting plate 24 can each be partially transparent, whereby additional optical effects can be achieved.

The illustrated reflector assembly 20 is - as in Fig. 1b can be seen - preferably from a plurality of individual modules 25, which are joined together in the longitudinal direction to the entire reflector assembly 20. The reason for the use of individual modules 25, each having four pot reflectors in the example shown, is that the modules 25 should preferably be designed in one piece and for this purpose can be produced, for example, by injection molding. However, an injection molding tool for producing a one-piece reflector arrangement over the entire length of the luminaire would be many times more expensive than the production of a plurality of smaller individual modules 25.

However, the arrangement or use of individual modules 25 involves the problem that it must be ensured that the modules 25 are also close to each other at their respective ends. Otherwise, columns would be created can escape through the light and thus the optical appearance of the lamp would be affected.

The juxtaposition of the individual modules is now made possible by the two spring tongues 34 in the lower portions 32 of the first U-leg 31 of the locking element 30. As the representations in the FIGS. 8 and 9 can be removed, press these two spring tongues 34 each on the end faces of the associated individual module of the reflector assembly 20, whereby the modules 25 are compressed in total in the longitudinal direction. The socket holder according to the invention thus not only allows a simple assembly or arrangement of the light sources in the lamp housing 2, but also ensures beyond that the optical effects generated by the latching arrangement 20 can be generated without interference.

It should be noted that the latching assembly 20 is otherwise not held by the grid holder 30. Instead, the individual modules 25 are inserted only in the housing frame and lie with lateral projections 26 and 27 (see FIG. 11 or FIG. 13 ) on corresponding bearing surfaces of the two lateral profile elements 10.

Overall, a light is thus created, which has a very elegant appearance and also achieved visually appealing lighting effects. The installation of the lamp as a whole is significantly simplified compared to previous profile frame lights.
