Definitions

  • the invention relates to a lamp, a lighting system and the use of a lamp according to the features of the preamble of the independent claims.
  • a variety of different reflectors and refractors are known.
  • Out EP 1 586 818 a luminaire is known in which two prism covers are used to redirect the light.
  • Out DE 195 47 747 is a luminaire with direct and indirect light propagation known. This is intended to generate a direct and indirect lighting proportion. In this case, strip-like prisms can be used.
  • Prismatic structures for the purpose of light deflection are also off DE 199 23 226 .
  • Out DE GM 89 15 821 is also a luminaire with a cover with a prismatic structure known, with which a zone of reduced luminance is to be created. This should be effected when using the lamp as a ceiling light directly below the light a zone of relative darkness. The main luminous flux should be emitted laterally and impinge on the corridor walls.
  • a problem with this solution is that viewers who step out of side doors into the hall are blinded by the emitted light.
  • the luminaire is intended to enable illumination which is not dazzling to the viewer.
  • a further object of the invention is to provide a lighting system which is versatile applicable and by means of which, for example in hospitals in a cost effective manner in addition to room lighting further lighting applications can be provided.
  • Another object of the invention is also to provide a lighting system by means of which different lighting needs can be met in a simple manner.
  • the luminaire according to the invention is provided with at least one luminous means and deflection means for deflecting the light emitted by the luminous means.
  • the deflecting means are designed in such a way that, when the luminaire is mounted as intended, a first illumination angle range extends approximately horizontally away from the luminaire and a second illumination angle range extends approximately perpendicularly downwards, and the first and second illumination angle ranges pass through an area with less Lighting intensity are separated from each other.
  • the inventive lamp is therefore particularly suitable for use in a hallway. Due to the primary lateral and secondary perpendicular radiation and due to the intervening area with lower illumination intensity, there is no risk that persons passing through a door into the corridor will be blinded by the luminaire mounted along the corridor.
  • the lamp is designed as an elongated lamp, which is also provided with an elongated lamp.
  • a lamp is particularly well suited for uniform illumination of a long corridor.
  • a plurality of such lights may be sequentially arranged along the corridor.
  • the intensity of the illumination in the first illumination angle range is different, in particular greater than in the second illumination angle range.
  • the illumination of the corridor takes place indirectly over the side wall of the corridor.
  • lower proportion of light is also a direct illumination of the room. It is particularly advantageous if the lamp is also provided with means for preventing a precisely vertical or vertical light emission. In this way it can be prevented that a person moving along the corridor is blinded by the light emitted downwards.
  • the first illumination angle range extends over an angle of about 75 ° to about 150 ° to the vertical.
  • the second angle range preferably extends from about 25 ° to about 60 ° with respect to the perpendicular. Due to the provided between 60 and 75 ° with respect to the vertical area with lower illumination intensity is caused by a ceiling mounting the lamp in a corridor with conventional dimensions that the Face of a passing from a side door in the corridor person is in the range of lower intensity.
  • the corresponding angular range can be adapted so that even with other dimensions of a corridor an aperture is prevented.
  • the luminaire is preferably constructed symmetrically, so that in mounting position of the luminaire along a corridor light is emitted on both sides in the direction of the side walls of the corridor.
  • two first and two second illumination angle ranges in the manner described above are provided on both sides.
  • the deflection means may be formed by a cover with a prismatic structure.
  • alternative solutions are conceivable by means of which the same effects could be achieved, for example elements with a microcone structure.
  • the cover has a plurality of mutually parallel prisms.
  • the prisms are preferably arranged on the inside of the cover, so that when viewed from the outside results in a smooth surface.
  • the prisms are particularly preferably arranged at regular intervals from each other, and they have an equal width of their base surfaces. This results from the outside a uniform arrangement of the prisms. Nevertheless, the desired deflection of the light can be achieved by different choice of the height or the position of the tip of the individual prisms.
  • two light sources in particular in the installation position one above the other, are provided in the luminaire according to the invention.
  • an identical prism structure is preferably provided for each light source.
  • the use of two bulbs also allows the use of bulbs with different emission spectra, which can be weighted according to need, for example, depending on the time of day, correspondingly stronger or less strong. This makes it possible to achieve a variable emission spectrum over time with suitable control.
  • the deflection means are designed in the form of a profile extruded as a panel. Such deflection means can be produced particularly inexpensively.
  • the base part can be of different lengths.
  • Essential here are certain common components such as the cross section or dimensions of the base part.
  • a luminaire system in which, in the case of a luminaire extending in the longitudinal direction, in particular a luminaire as described above, an interface is provided at least at one of its ends in the longitudinal direction.
  • the lighting system has at least one additional module which can be connected to the interface. For example, while using it of lights for corridor lighting individual spot modules are arranged, which allow individual lighting of individual areas, such as images on a wall.
  • Yet another aspect of the invention relates to the use of a lamp as described above with Umlenkanssenen in a long-drawn room, especially in a hallway, wherein the lamp is used such that in a first illumination angle range light on a wall above a predetermined height, in particular above 2.00 meters is emitted and that in a second illumination angle range light is given directly into the room.
  • luminaire according to the invention Glare and reflections are reduced. Due to the indirect lighting via walls and partly direct lighting results in a low shadowing. The indirect illumination of the side walls of a corridor results in an optical broadening. Because the luminaire according to the invention can be mounted directly on the ceiling, it is also ideally suited for low room heights.
  • FIG. 1 shows a perspective view of a luminaire 1 according to the invention.
  • the luminaire 1 according to the invention is designed substantially as an elongated cuboid.
  • the lamp 1 should be mounted with one of its narrow sides 6 on a ceiling.
  • the lamp 1 has a base part 3, which is mounted or mounted on the ceiling.
  • the base part 3 has not shown mounting means for mounting the lamp to the ceiling D.
  • the mounting position of the lamp 1 is defined based on the ceiling.
  • a holder for two bulbs 2a, 2b, typically fluorescent tubes, is provided at the base part 3 a holder for two bulbs 2a, 2b, typically fluorescent tubes, is provided.
  • the lighting means 2a, 2b are covered by a transparent cover 10, which causes a deflection of the light in the manner described below.
  • a cover is also provided, which prevents direct radiation of the light in the vertical direction V down.
  • the luminaire 1 is typically mounted in the longitudinal direction L along a corridor.
  • the lower cover 20 thus prevents glare from moving along the corridor persons.
  • FIG. 2 shows a section through the luminaire according to FIG. 1 in a plane perpendicular to the longitudinal direction L.
  • the lamp 1 is mounted with the base part 3 on the ceiling D.
  • the bulbs 2a, 2b are arranged one above the other in the vertical direction.
  • the cover 10, which serves as a deflection means for the light is integrally formed.
  • the lighting means 2a, 2b are covered on three sides by the cover 10.
  • On the inside of the cover 10 a prism structure 11 is arranged, which causes the deflection of the light in the desired manner.
  • an additional lower prism structure 11 is provided at the lower surface in the mounting position of the cover 10.
  • the prism structure 21 prevents direct emission of light in the vertical direction V by refraction of light.
  • a lower cover 20 can also be provided which completely prevents vertical light emission.
  • the emission characteristic of the luminaire according to FIG. 2 is shown in FIG.
  • the prism structure 11 is formed such that light in the first illumination angle ranges B1 is emitted approximately horizontally from the luminaire 1 on both sides.
  • the illumination angle ranges B1 extend with respect to the vertical V over an angular range of about 75 to about 120 °.
  • a second illumination angle range B2 light is also emitted, but at a lower intensity.
  • the second illumination angle range B2 extends over a range of 40 to 60 ° relative to the vertical.
  • the intensities in the first and in the second illumination angle range B1, B2 can be selected depending on the field of application. Typically, the intensity may be distributed such that 80% of the radiated light is emitted in the first illumination angle range B1, resulting in indirect illumination, and that 20% of the intensity is delivered as direct illumination in the second illumination angle range B2.
  • the two illumination angle ranges B1, B2 are each separated by a region G with a lower light intensity.
  • the lower intensity region G typically extends from about 60 to 75 degrees with respect to the vertical V.
  • FIG. 4 a shows a cross section through the cover 10.
  • the cover 10 is extruded as a profile of a transparent material, for example of polycarbonate or polymethyl methacrylate (Plexiglas, PMMA).
  • a prism structure 11 in the form of a plurality of juxtaposed prisms 12 is arranged on the inside of the profile. So that a uniform structure can be seen from the outside, the prisms have a base 13 (see enlarged illustration in FIG. 4b), which has an equal width B for each individual prism 12, typically 3 mm.
  • the individual prisms 12 differ in their shape and in their height h. As a result, the desired light distribution can be achieved.
  • a different shape means different angles of the prisms.
  • the tips of the individual prisms are arranged differently, resulting in different angles ⁇ 1, ⁇ 2, ⁇ 3 of the individual prism tips.
