Definitions

  • the present invention relates to a lamp, in particular a ceiling or wall lamp according to the preamble of claim 1, which has a trough-shaped housing for receiving or holding at least one light source and a cover for the housing, which is at least partially translucent.
  • the luminaire according to the invention is intended in particular to emit light uniformly over a larger area.
  • a wide variety of luminaires are known from the prior art, which initially have a substantially square trough-shaped luminaire housing in which a plurality of light sources and operating devices for operating the light sources are arranged.
  • the light output of these lights is usually on transparent discs, which are arranged in the housing opening and light scattering effect.
  • additional optical elements such as reflectors or other scattering elements are used, which are arranged inside the housing. It is also known to arrange several of these lights next to each other and to combine them into a larger light field.
  • the present invention is based on the object to provide a novel design for such lights, which allows a uniform as possible light output even with larger luminaire dimensions despite a simple structure.
  • the solution according to the invention is based on the idea to provide a novel construction for the cover of the lamp, which is relatively simple in construction and despite all allows a uniform distribution of light.
  • a cover which has a frame which is covered with at least two translucent materials, which are seen from one another in the light emission direction.
  • a luminaire in particular a ceiling or wall luminaire is accordingly proposed, which has a trough-shaped housing for receiving or holding at least one light source and a cover for the housing, which is at least partially translucent, according to the invention, the cover has a frame which is covered with at least two - in the light emission direction - spaced apart transparent materials.
  • the two coverings of the cover have a different sound transmission.
  • the light-permeable clothing facing the housing has a low sound transmission
  • the sound transmission of the clothing which is more remote from the housing is markedly higher. The sound is no longer reflected in this case by the cover but rather penetrates into the space between the two fabrics, which ultimately has the consequence that the lamp according to the invention even causes a sound insulation.
  • the lamp according to the invention is particularly suitable for use in large-scale fields in which a plurality of lights are arranged side by side to form a larger luminous surface.
  • the two fabrics of the cover can be formed, for example, by films or fabric.
  • the frame of the cover is preferably formed of aluminum profile elements.
  • a free space remains between the frame of the cover and the housing, via which a lateral light emission is made possible.
  • the side walls of the cover are formed by transparent elements which are fastened to the frame construction. These transparent elements may in particular be satin-finished plastic elements.
  • the cover is preferably detachably connected to the housing.
  • magnetic or latching connections can be provided.
  • the luminaire 1 initially has a square-shaped trough-shaped luminaire housing 2, which is formed in the usual way from sheet metal.
  • a square-shaped trough-shaped luminaire housing 2 On the bottom surface 3 of the lamp housing 2 are holders for light sources and associated control gear, in the illustrated embodiment, as fluorescent light sources 5 are used, which are operated by associated electronic ballasts 6.
  • the fluorescent lamps 5 are arranged distributed over the bottom surface 3 of the housing 2 in order to optimize the uniform light output.
  • other light sources could be used.
  • the use of LEDs would be conceivable.
  • light sources which emit light in different colors in order to generate light of any desired mixed color or arbitrary color temperature by means of a corresponding brightness control of the individual light sources.
  • additional optical elements such as reflectors and the like can also be arranged on the housing 2 -not shown in detail.
  • other shapes, in particular rectangular shapes or oval shapes may also be used.
  • the outer dimensions of the cover 10 essentially correspond to the dimensions of the luminaire housing 2, so that overall, a flat, cuboidal shape for luminaire 1 results.
  • lights could be provided in a size of 600 x 600mm or 900 x 900mm, of course, any sizes could be realized.
  • the cover 10 has a peripheral frame 11 which is formed of a plurality, in particular of four aluminum profile elements 12, which are joined together in miter to the frame structure 11.
  • This frame construction 11 is connected to the luminaire housing 2 via latching connections 30 which will be described in more detail later.
  • a first particularity of the frame structure 11 is that the aluminum profiles 12 are arranged inclined, with the result that between the lamp housing 2 facing the end 13 of the profile parts 12 and the side wall 2a of the lamp housing 2 is a free space F (shown in FIG Fig. 5 ) remains, over which light emitted by the lamps 5 can enter an outer region of the frame construction 11.
  • a free space F shown in FIG Fig. 5
  • 12 transparent plastic parts 15 are arranged on the outer sides of the profile elements, which are inserted with two elongated projections 16 in corresponding recesses 14 of the aluminum profile elements 12.
  • the plastic parts 15 are preferably made of a satin-finished plastic and are L-shaped, wherein the short leg 17 is disposed in the region of the free space F and the longer leg 18 forms the outer surface of the cover 10. A part of the light emitted by the lamps 5 light can thus enter via the short leg 17 in the outer region of the frame structure 11 and is then emitted laterally over the side walls 18 so that the lamp 1 according to the invention can also emit light sideways. This is particularly advantageous when the lamp 1 is arranged individually. Even in the event, however, that several of the lights are joined together to form a larger field, the lateral radiation brings advantages, since even in the transition region between two adjacent lights, a certain light output is achieved and, accordingly, no dark transition areas occur. It would be natural as well It is conceivable to use colored plastic parts 15 or separate color filters in order to emit colored light over the outer circumference of the luminaire 1.
  • the majority of the light emitted by the light sources 5 should of course be emitted in a direction perpendicular to the bottom surface 3 of the housing 2.
  • the light is emitted via two spaced-apart clothing 20 and 21.
  • corresponding recesses 19 are provided for this purpose in the aluminum profile elements 12, through which peripheral channels for clamping the translucent materials 20 and 21 are formed.
  • the coverings can then be hooked into these channels with the aid of at least partially circumferential piping.
  • Both coverings 20 and 21 have a light-scattering effect, so that twice as much scattering of the light emitted by the light sources 5 results in the most uniform possible light output over the entire light exit surface.
  • the clothing 20 and 21 are designed in a special way to cause in addition to a uniform light output and a sound insulation.
  • the outer covering 21 is relatively well sound-permeable, while on the other hand, the housing 2 facing inner fabric 20 has a lower sound transmission. Sound impinging from outside on the surface of the luminaire 1 can accordingly penetrate into the intermediate space between the two coverings 20 and 21, but is held captive, so to speak, so that the luminaire 1 according to the invention actually also effects a reduction of the noise load.
  • the number of clothing could also be increased, in which case the sound transmission of the clothing to the housing preferably decreases.
  • the desired effect namely on the one hand to support a uniform light output and on the other hand to dampen sound is already achieved in the illustrated example with two fabrics.
  • the cover 10 is connected to the luminaire housing 2 via connections 30 arranged in the corner regions.
  • snap-in connections are used which have a first spring element 32 fastened to the profile elements 12 via a screw 31.
  • This cooperates with a second spring element 33, which in turn is attached via a further screw 34 to the lamp housing 2.
  • the second spring element 33 is angled and accordingly has a latching nose 33a, which engages when placing the cover 10 on the housing 2 in a recess 32a of the first spring element 32.
  • magnetic connections could also be used, in both cases having a positive effect that the cover 10 has a relatively low weight due to the construction according to the invention.
  • the fabrics 20 and 21 different materials, e.g. Depending on the application, certain materials can be selected to achieve different appearances for the luminaire. Basically, however, a uniform light output over the entire surface of the luminaire is achieved with the help of the inventive design, in addition, the lamp is also acoustically effective, thus causing a sound insulation. By backlighting the outer surface of the cover also appears the total height of the lamp additionally reduced, so that the lamp not only has positive photometric and acoustic properties, but overall looks visually very appealing.
