Definitions

  • the invention relates to an interior light, comprising a lamp body with at least one light source, which is arranged in a provided with a light exit opening lamp interior.
  • the room acoustics is increasingly taken into account in order to achieve acoustic properties of a room according to its intended use. It should be noted that a radio or television studio does not have the same acoustic requirements as an auditorium, a church or a theater basement and a meeting room does not need the same room acoustics as an open plan office or a living room.
  • a room with good room acoustics ensures a better well-being and reduces the stress factor noise. Therefore, it is very important in rooms where you spend a long time, such as in office rooms, that the room acoustics are pleasant.
  • a fixed room such as a large office, is therefore always a compromise between acoustics and different properties.
  • this compromise can be optimized by flexible, movable elements such as heavy curtains, partitions, acoustic body, etc., to suit the respective requirements.
  • Room acoustics problems such as reverberant rooms due to a long reverberation time, can be subsequently corrected relatively easily. Offices are not qualified over a reverberation time to be achieved. In such spaces, which include corridors, ticket halls, call centers or libraries, the amount and arrangement of sound-absorbing surfaces is of utmost importance to the listening experience and the acoustic environment.
  • the aim of soundproofing is to acoustically separate individual rooms or areas within a room. Airborne sound is moved by the vibration of the air in the room and is caused by various noise sources such as voices, music or machine noise. In order to prevent the propagation of airborne sound, room acoustics and sound insulation measures can be used. Room acoustics absorb some of the sound and convert it into heat. This shortens the reverberation time. Soundproofing measures reflect sound and keep it in or out of the room.
  • the document DE 20 2007 007 229 U1 shows, for example, a lighting arrangement for illuminating a workstation, which comprises means for active sound absorption.
  • a phase-shifted to the ambient noise counter-signal is selectively emitted.
  • This requires a microphone that is integrated into the luminaire and detects environmental noise.
  • the signals detected by the microphone are transmitted to a control unit, which performs a corresponding control of speakers, which are also integrated in the lamp.
  • the sound counter signal emitted via the loudspeaker then ensures at least partial cancellation of the ambient noise.
  • a disadvantage of this design is that due to the numerous electronic components such as microphone, control unit and speakers, the lighting arrangement in the purchase is very expensive. A sound-insulating effect of the lighting arrangement in the currentless operation is not achieved, which represents a further disadvantage of such a lamp.
  • the publication DE 198 57 736 C2 relates to a shield arrangement for a table arrangement with at least one horizontal or vertical shielding for light or sound attached to a support structure, the support structure comprising at least two columns fixed to the two narrow sides of the table frame.
  • lights are provided within the shield mounted horizontally and transversely above the table top.
  • the outer layer of this roof-like shield can be designed as a cloth, foil or plate-shaped material.
  • a disadvantage of this design is that the shielding is fastened exclusively to a table and therefore not set up flexibly anywhere in the room can be. Furthermore, it is disadvantageous that luminaires which are provided inside the shielding device are not individually adjustable in their height distance or their position relative to the working surface.
  • a disadvantage of this design is that the sound absorber plates are fixed in place and can not be moved as a flexible, movable elements for acoustic insulation of a work or meeting area within a room. Furthermore, it is disadvantageous that the LED lights do not allow adequate workplace lighting due to the usually large distance between their mounting position on the suspended from the ceiling sound absorber plates and a work surface below a table.
  • the object of the present invention is to overcome the disadvantages known from the prior art and to provide a luminaire which can be flexibly positioned in space and adapted to the individual requirements of a workstation or communication area and which also has a sound-absorbing effect when de-energized Has.
  • an interior light comprising a lamp body with at least one light source, which is arranged in a provided with a light exit opening lamp interior, provided with a sound-absorbing molded body.
  • the interior light In such an interior light all conceivable bulbs can be used.
  • a lighting means for example, one or more fluorescent tubes or multiple LEDs in the interior of the lamp can be arranged.
  • the interior light is particularly advantageous provided with a sound-absorbing molding.
  • This sound-absorbing molded body forms for example a portion of the lamp body and serves for sound absorption, especially in open-plan offices. Meeting zones or workstations are particularly effectively reduced by one or more interior lights according to the invention, which are flexibly placed directly next to it.
  • the interior lights according to the invention are not subject to any restrictions on their shape and design. It is conceivable, for example, to carry out such interior lighting equally as floor lamps, suspended lamps or wall lamps.
  • the sound-absorbing molding is arranged so that it at least partially surrounds the interior of the lamp.
  • the sound-absorbing shaped body in the case of an interior light, has a disk-shaped surface.
  • the molded body forms a particularly large sound-absorbing luminaire surface.
  • a thus designed interior light which is designed for example as a floor lamp or as a wall light, has a particularly effective sound absorption.
  • At least one section of the shaped body is particularly advantageously provided with recesses open on one side.
  • the recesses are by no means limited to a portion of the molded body.
  • the molded body can also be provided with depressions on all its outer surfaces. For example, recesses can be provided both on the upper side and on the lower side of the molded body.
  • the depressions are arranged substantially perpendicular to the surface of the shaped body. Sound, which is incident approximately perpendicular to the surface of the molding, passes directly into the recesses of the molding and is thus absorbed particularly effective within this. Furthermore, this embodiment of depressions arranged approximately perpendicularly to the surface of the molded body is particularly simple and cost-effective in its manufacture, which represents a further advantage of the invention.
  • the recesses are designed as cylindrical or polygonal recesses with a depth of 5 mm to 100 mm and a diameter of 5 mm to 100 mm.
  • depressions with a circular, square or rectangular as well as polygonal cross-section are conceivable.
  • the transitions between the side surfaces and the end faces of the recesses are each rounded or bevelled.
  • the transitions from the outer surface of the shaped body into the depressions can each be rounded off or beveled. Depths of a few mm to about 100 mm and diameters of 5 mm to 100 mm have proved to be suitable as dimensions of the recesses open on one side.
  • the selection of the corresponding dimple dimensions is influenced both by the sound frequencies to be absorbed and by the aesthetic design of the molded body or of the luminaire body.
  • an interior light on a multi-part molded body In one embodiment of the invention, an interior light on a multi-part molded body.
  • the design of an interior light according to the invention have no limits. It is thus conceivable to arrange a plurality of parts of identical or differently shaped moldings on one and the same interior light.
  • the individual shaped bodies can be attached to each other adjacent to or spaced apart from the interior light.
  • large-scale installations of an interior light which has, for example, a plurality of lamp interiors, of the invention.
  • the shaped body is produced from a material containing polystyrene foam.
  • Such materials containing polystyrene foam are particularly inexpensive and easy to work and bring in the particular desired shape. It is also possible to use other materials suitable as sound-absorbing material for producing the at least one sound-absorbing molding.
  • an interior light in which the surface of the shaped body is covered with at least one sound-absorbing covering layer.
  • Such a sound-absorbing covering layer offers the advantage that the surface of the shaped body, in particular the surface provided with depressions, is covered with the covering layer.
  • a sound-absorbing covering layer in addition to a sound-absorbing effect at least for high frequencies, also serves to improve the look and feel of such luminaires.
  • the inner molded body which can be made of an easy-to-work, cost-effective material such as polystyrene foam (Styrofoam ®) is thus invisible to the viewer through the outer covering layer. It is also conceivable to provide a luminaire according to the invention with a plurality of layers of covering layers. It is also possible to choose different materials for the individual clothing layers.
  • the at least one covering layer is made of a textile.
  • the invention encompasses all variants of textiles for the design of one or more clothing layers.
