Lamp with elongated housing

technical field

The invention relates to a lamp having an elongated housing which is formed from a profile part which is divided into a plurality of channel-like regions extending longitudinally of the housing for receiving light sources and possibly optical elements , wherein each channel-shaped area is equipped with at least one light outlet for light output.

Background technique

A corresponding lamp is known, for example, from EP1365189A2 and is used, for example, in hospitals. The lamp serves to emit light towards the top side in the sense of indirect emission of light. Furthermore, a reading light is to be provided for the patient, this is done in such a way that the light output is additionally also directed towards the underside. Typically, such lamps are mounted near or in the immediate vicinity of a channel-like structure in which lines for medical gases such as compressed air, nitrogen and oxygen run.

The main component of the lamp disclosed in EP1365189A2 is a profile part, which is the load-bearing part of the lamp and is mounted on a bracket such as the wall of a patient room. The profile part is used to hold or accommodate a plurality of light sources and to this end forms a channel-like receiving area which is open towards the top side. A plurality of light sources are arranged in this area, the light of which is directed towards the top side by means of a reflector. The light outlet is covered here by a transparent part which snaps onto the profile part. In this case, the snap-on cover also bridges over the front area of the profiled part and thus forms a further receiving area with another light source. The light of this further light source is essentially emitted towards the underside, that is to say used, for example, as a reading light for a patient. Overall, a structure is thus provided whereby the above-mentioned desired light output towards the top side and the bottom side is achieved.

Contents of the invention

The object of the present invention is to provide a novel design for a corresponding lamp which has improved properties with regard to robustness. Furthermore, the mounting of eg a transparent cover on the lamp should be simplified.

Here, the first aspect of the invention relates to the design of the profiled part. It is provided here that the plurality of channels and the corresponding plurality of light outlet openings of the profile part are such that not only light emission towards the top side but also light emission towards the bottom side is possible. In particular, in contrast to the solution known from EP 1365189 A2 in which the bulb provided for emitting light towards the underside is arranged outside the profile, it is provided that all light sources are now arranged inside the profile. This results in a much more stable structure, which nonetheless achieves the desired light output.

According to a first aspect of the invention there is correspondingly provided a lamp with an elongated housing, which is formed from a profile part which is divided into a plurality of channel-like, extending longitudinally of the housing, for The area that houses the light source and possibly the optical elements, each channel-like area is equipped with at least one light outlet respectively for the light output, and for the case where the lamp is mounted on a substantially vertically oriented bracket such as a wall, all the light outlets A light output not only towards the top side but also towards the bottom side is achieved.

The profile part is preferably formed in one piece, as a result of which the overall achievable stability is again increased. In this case, the profile part preferably forms two substantially U-shaped channels, which are provided on the one hand to receive light sources for indirect lighting and on the other hand to receive light sources or light sources for direct lighting. For example, it can be provided that both channels are open towards the same side, one of the two channels then also having a further opening for light output on its bottom side. Light sources can then be arranged in this channel, the light of which also emits towards the bottom side and, if desired, also towards the top side.

Furthermore, the profile part designed according to the invention can also have means for fastening an attachment component, in particular another profile part. Accordingly, the lamp can be arranged, for example, on a channel which, as described above, is used for supplying medical gases such as compressed air, nitrogen and/or oxygen, but also for supplying electric current.

Another aspect of the invention relates to the mounting of the cover on the profile. The cover can be, for example, a cover of transparent design, which covers the light outlet and accordingly affects the light output and prevents the ingress of dust. At the same time, however, the cover can also be a cover which closes or covers the side regions of the profiled part and accordingly represents a decorative part which influences the appearance of the lamp. The cover should preferably be fastened detachably to the profile part, here, according to a further aspect of the invention, it is provided that the fastening takes place via elongated profile parts, which can be mounted on The cover is clamped and held in the recess or recess of the profile part and in the installed state.

Detailed ways

The lamp according to the invention shown in FIGS. 1 and 2 and generally designated by the reference numeral 1 is provided as already described for providing illumination, for example, in a hospital patient room. Here, light is to be emitted towards the top side and the bottom side by the lamp 1 , which is preferably fastened to the wall of the building. The light emitted towards the top side is used for house lighting, while the light emitted downwards is especially reflected as a reading light.

The lamp 1 has a flat elongated housing 2 which, as described in detail below, is formed in particular from an elongated profile part. The profile part is closed at its two ends by end parts 3 , the upper side being covered by a transparent cover plate. On its bottom side, the profile part 10 has an opening 11 in the region of the front side, which is used to output light toward the bottom side. Thus, the above-mentioned reading light is formed.

In particular, the detailed design of the profile part according to the invention can be obtained from FIGS. 3-7 . As shown in FIGS. 4 and 5 , the profile part 10 , which can be formed, for example, as an extruded aluminum profile, is designed in such a way that it forms two longitudinally extending channel-like regions 12 and 13 . Different light sources are arranged in said areas 12 and 13 . Here, FIGS. 3 and 6 firstly show the light sources 6 located in the front channel 13 , which can be formed, for example, by elongated fluorescent tubes. Then, by using the reflector 7 surrounding the bulb 6, the light from the bulb 6 is guided to the light outlet 11, and is emitted toward the bottom side accordingly. Via the slope of the two reflective surfaces 7a and 7b, the opening angle of the downwardly emitting light beams can be influenced.

Light sources for the indirect output of light (ie directed towards the top side) are arranged in the rear channel 12 , which are not shown here in the drawing for the sake of clarity. However, two reflectors 15 and 16 are shown, by means of which the light is directed upwards. Correspondingly, the upper opening of the channel 12 constitutes a corresponding light outlet. The positions of the preferred two elongated fluorescent tubes are indicated by crosses in FIG. 3 .

In order to install or fix various components in the channels 12 and 13, such as lamp holders or reflectors, the profile part 10 also has a longitudinally extending screw channel or screw groove 18, which is oriented obliquely towards the top side and allows the installation of the above-mentioned member. In addition, the elongated notches or protrusions of the profiled part 10 can be used to clamp the reflector or the like.

That is to say, in the exemplary embodiment shown, provision is made for the profile part 10 to form two elongated channels 12 and 13 which permit the accommodation of light sources not only for indirect lighting but also for direct lighting. Since the receiving area of the profiled part 10 also includes the front light source 6 for direct lighting, overall a stable arrangement of the lamp 1 is provided.

The profiled part 10 is closed towards the top side by means of the above-mentioned transparent cover 20 which forms the top side of the housing 2 . A transparent cover 20 can be fastened detachably to the profile part 10 for gaining access to the interior of the lamp 1 in case maintenance measures are required. Furthermore, the front side of the housing 2 can be formed by a decorative part 25 which can also be removed, which is also designed to be replaceable. As a result, the appearance image of the lamp 1 can be affected.

The detachable or detachable fastening of the attachment elements 20 , 25 on the profiled part 10 takes place by means of a plurality of elongated profiled parts 30 , the structure of which can be seen in particular in FIG. 7 . These profiled parts 30 extend over the entire length of the profiled part 10 and are formed as clamping parts. For this purpose, they can be mounted in corresponding elongated notches or grooves 19 of the profile part 10 . In this case, the elasticity of the profiled part 30 is achieved in that it has two elongated webs 31 spaced apart from one another, which are connected by a transverse bar 32 . When installed in the groove 19, these webs 31 are slightly pressed together and, because of their elasticity, serve to stay securely in place. The fastening of the profiled part 30 to the profiled part 10 can also be improved in that both the inner surface of the longitudinal groove 19 and the outer surface of the web 31 are slightly corrugated.

As can now be seen in particular from FIG. 3 , the transverse strip 32 of the inserted profiled part 30 straddles the lateral edges of the transparent cover 20 and the front trim part 25 and holds these components accordingly. on the profile part 10 . In this way, fastening of the component is provided in a simple manner, where the holding can be released at any time, for example in order to replace the trim part 25 or to remove the cover 20 for maintenance. In particular, this can also be done in the already mounted state of the lamp 1 . It is also conceivable to provide a transparent cover on the underside of the front channel 13 . For this purpose, two lower profile parts 30 can be used.

Furthermore, another characteristic feature of the profiled part 30 is that it preferably consists of a transparent material, in particular polycarbonate. This refinement has the result that a small fraction of the light emitted by the light source is incident on the profiled part 30 . The profiled part first acts as a light guide, ie the incident light is distributed in the longitudinal direction. At the same time, however, a small amount of light is also emitted, which ultimately leads to a slight glow of the profiled part 30 towards the outer surface. As a result, when the light source is powered on, a very eye-catching effect will be obtained. The appearance of such a lamp 1 is thereby further added in value. Of course, however, the profiled part can also be colored transparent or opaque.

It should also be noted that in particular the upper reflective surface 7a of the front reflector 7 can also be configured translucently. In this case, a small amount of light is again directed towards the top side, which has the result that the transparent cover 20 is also illuminated in this region. Also, the front trim 25 may also be configured to be light-transmissive. The front trim part can then be slightly illuminated in that corresponding openings are provided on the front wall of the profile part 10 . As a result, most of the outer surface of the luminaire housing is slightly illuminated.

As shown in FIG. 7 , it can also also be provided that a further profile part 40 is provided on the underside of the profile part 10 . It can here in particular be an elongated channel for accommodating a supply line via which the patient treatment substance can be supplied. In this case, the substance may be compressed air, nitrogen or oxygen. Electrical or communication lines can also run in this channel.

Overall, a lamp is provided which on the one hand has a high mechanical strength and on the other hand has a visually attractive appearance, in particular the possibility of being exchangeable in a simple manner. Or change the add-on components used for light output and affect the appearance of the lamp.
