    description
    LAMP
    The present invention relates to a lamp according to the preamble of claim 1, which has a housing defining a light exit opening, wherein in the housing are arranged light means. In particular, with the aid of the luminaire according to the invention, the artificial light output should be adapted in a particularly elegant manner to the natural daylight or supplement the natural daylight.
    Daylight-dependent lighting controls have been known for a long time, especially when illuminating larger buildings or building complexes. Controlling the artificial light as a function of the daylight entering from outside not only leads to a more suitable lighting situation, which improves the so-called room climate, but also serves to save energy. The fact that the artificial light is switched on only when the natural daylight does not ensure sufficient brightness, the Energiever¬brauch a lighting system can be significantly reduced.
    The daylight usually falls on windows in a room to be illuminated, the lights, which are responsible for the complementary artificial light, then beispiels¬weise arranged or fixed to the ceiling of the room or distributed as Stehleuch¬ten within the room to be ordered. A light incidence of daylight is sometimes even when in the ceiling area windows or glazed or generally translucent structures are arranged. However, the lights responsible for the artificial light are then again arranged adjacent to these translucent structures in opaque ceiling areas.
    With the present invention, a luminaire is to be made available, the invariably novel way allows a coordinated illumination of a room by both daylight and by artificial light.
    The object is achieved by a luminaire, which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
    The concept of the invention is based on the idea to use the light exit opening of the luminaire, which is provided for the delivery of artificial light, in addition, as a light exit surface for natural daylight. That is, both types of light are emitted over the same area, resulting in a particularly harmonious combination zwi¬ natural light and artificial light. This combination of the two types of light is thereby achieved in that the housing of the luminaire is designed to be open or translucent even at the opposite rear side of the light exit opening, so that the natural daylight, which occurs from above or from behind the lamp, is passed through the housing and this then leaves via the light exit opening.
    According to the present invention, therefore, a lamp with a housing which defines a light exit opening, as well as arranged in the housing bulbs proposed, according to the invention, the housing at the light exit opening gegenüberlie¬genden rear side is at least partially transparent or open and the arrangement the luminous means within the housing is such that light entering the housing via the rear side can leave it via the light exit opening.
    The solution according to the invention makes it possible to fill with the help of such lights a Decken¬bereich a building or a room with so-called light tiles, on the one hand, the natural daylight can fall into the room and gege¬benenfalls also artificial light is emitted. The previous division between windows or glass fronts through which daylight is incident and luminaires arranged separately therewith is eliminated, thus resulting in an interesting appearance of the room as a whole. As will be explained in more detail below, the luminaires can also be used for other purposes, such as sound damping or the like, due to the fact that they can occupy very large areas.
    Preferably, the housing of the lamp according to the invention is like a frame and accordingly completely open to the rear. The housing is vorzugswei¬se rectangular, in particular square shaped, in this regard, of course, there is no limitation and other forms would be conceivable.
    The lighting means are arranged according to a preferred embodiment of several elongated support members which extend substantially parallel and spaced from each other through the housing. In this case, the bulbs can be formed insbeson¬dere by LEDs. Through the spaces between the support elements with the bulbs, the daylight can then pass through and finally be emitted via the light exit opening.
    The support elements for the light sources, in particular for the LEDs are preferably formed by profile parts, in particular aluminum profile parts, which are each attached with their front ends to the housing. These profile parts can be formed web-like and initially have a receiving area for holding LED boards. Vondiesemem receiving area may then extend to the rear side a web area, which is preferably in the form of a heat sink, that has a plurality of side arms, which increases the surface and thus the heat exchange is optimized for the surrounding air. In addition, the carrier elements can be used at the same time for holding pri¬märoptiken for the LEDs, these primary optics are designed to support a uniform light output of the artificial light.
    Thus, even in the situation in which is emitted by the light only daylight, the light exit surface appears evenly bright, it is preferably provided that in the intermediate regions between the support elements additional optical elements for influencing the passing through (day) light are arranged. Also in this case, the support members may serve to support these optical elements. For example, they are formed by elongate plates having a patterning in the form of prisms or the like, through which a uniform distribution of daylight is achieved. As already mentioned, the primary optics for the illuminants also have a comparable function, so that the light exit surface of the luminaire is brightened as uniformly and homogeneously as possible both by the daylight and by the artificial light.
    As already mentioned, the luminaire according to the invention is preferably realized as a large-area luminaire, which can then also be used for other purposes to improve the Raum¬klimas. According to a preferred embodiment, it may be provided that the luminaire has a translucent cover in the region of the light outlet opening, the cover having a frame which is covered with at least two translucent materials which are spaced apart from one another in the direction of light emission. This idea is already known from the Applicant's EP 2 221 528 A2 and is used in particular to effect sound insulation. Furthermore, however, with the help of these materials, the light output of the lamp can be selectively influenced. Sowäre particular conceivable that the materials act light scattering, so that an insight into the interior of the lamp is prevented.
    The sound-absorbing effect of this special cover is achieved in particular when the two translucent materials have a different Schalldurchlässig¬keit. In particular, the translucent material facing the housing has a lower sound transmission, whereas the sound transmission of the more distant clothing, which ultimately forms the light emission surface of the luminaire, is markedly higher. In this case, the sound from the cover is no longer reflected but penetrates into the space between the two materials, with the result that the desired sound insulation is achieved. The two materials may, in particular, be films or fabrics.
    The invention will be explained in more detail with reference to the accompanying drawings. FIG. 1 shows an exemplary embodiment of a luminaire according to the invention in a perspective view from below; Figure 2 is a side view of the lamp according to the invention; FIG. 3 is an enlarged sectional view of the luminaire according to the invention; Figure 4 is an exploded view of the support elements for the lamps and the optical elements arranged thereon, and Figures 5a and 5b representations of the effect of the lamp according to the invention in the
    Light emission from daylight and artificial light.
    As an embodiment of the invention, a square, generally provided with the reference numeral 100 lamp is shown in the figures. It is a luminaire, which is usually placed below a translucent ceiling structure of a building, through which the daylight can enter the building or the room that is to be illuminated. It is provided with the aid of a plurality of such lamps 100 completely fill a larger area, so that falls on the arrangement thus formed both the daylight and the artificial light in the room. Preferably, therefore, the illustrated square shape is provided for the luminaire 100, in which context, of course, there are no restrictions. In general, however, it will be relatively large area lights, for example, have an edge length of 1 m or more.
    According to the side view according to Figure 2, the lamp is slightly stepped formed and has an upper housing part 10, on the underside of which a cover 50 is additionally arranged. The cover 50 is slightly larger than the housing 10 in terms of their dimensions, in which case when joining several lamp 100, the covers abut each other laterally and corresponding fastening means for mounting the lamp 100 can be attached to the housing 10.
    The central idea of the luminaire 100 according to the invention is the Schnittdarstel¬lung of Figure 3 can be removed. It can be seen here that the housing 10 does not have a rear-side, essentially closed bottom surface, as is normally the case, on which the assembly of the various components of the luminaire 100 takes place. Instead, the housing 10 is in the shape of a frame and accordingly has on its rear side an opening 11 extending almost over the entire width. If necessary, this opening 11 could be covered by a light-transmitting element, but it is preferably provided that no corresponding cover is used, but the lamp 100 is actually open to the rear. The underside of the housing 10 defines a Licht¬austrittsöffnung 12, through which the light is emitted. In the present case, as already indicated, the light output takes place via an additional cover 50, which is arranged below the housing 10 and whose configuration will be explained in more detail below.
    Within the housing 10 a plurality of bulbs are arranged, with the aid of the same time artificial light over the entire surface of the lamp 100 can be discharged away. In the present case, LEDs 21 are provided as lighting means which, as shown in FIG. 4, are arranged on elongate circuit boards 20. The holder of the LED boards 20 takes place by means of a plurality of profile parts 15, which run parallel to each other through the lamp housing 10 and attached to their front ends of the frame-like housing 10, for example, with a slightly raised web 13 of the housing wall are screwed. Within the housing 10 further operating devices 14 are arranged to the power supply of the lamp.
    The profile parts 15 are formed, in particular, by web-like aluminum profiles, which, as shown in FIG. 4, have a receiving area 16 for supporting the LED boards 20 on their side facing the LEDs 21. From this Aufnahmebe¬reich 16 extends to the back, in the case of mounting so upwards a web-like area 17, which has a plurality of laterally branching arms 18. As a result, the profile element 15 forms a heat sink, via which during the operation of the LEDs 21 occurring heat can be efficiently dissipated to the environment. This heat dissipation is supported by the fact that, as already mentioned above, the rear side of the luminaire 100 is preferably completely open.
    Another function of the profile elements 15, which carry the bulbs 20, consists in the holder of a primary optics for the LEDs 21. This primary optics 22 consists of a plastic part made of translucent material which is triangular or wedge-shaped in cross-section. Longitudinal prisms or scattering structures 23 are formed on the two side flanks of the element 22, by means of which a uniform distribution of the LED light is achieved. This prevents the individual LED rows from appearing as brightly illuminated areas upon activation of the artificial light.
    The attachment of the primary optics 22 to the support elements 15 by means of zwei¬er provided on the rear arms 24, which engage in corresponding guide tracks 19 andem profile part 15.
    Characterized in that the support elements 15 with the light sources 20 each beabstandetzu each other through the lamp housing 10, intermediate free spaces are formed, which allow the passage of daylight. According to a particularly preferred embodiment, however, it is provided that these intermediate regions also have optical elements by which the emission of daylight is optimized. These are disk-shaped transparent plates 25, which in turn are held by the carrier elements 15. As can be seen in FIG. 3, these plates 15 bear against their edge regions 26 on the rear sides of the wedge-shaped regions of the primary optics 22. At its lower side, the plates 22 again have an elongate groove structure 27 which is comparable to the structure of the primary optics 22. Here, too, the structure 27 serves to distribute light passing through the light more evenly and accordingly to ensure a homogeneous delivery of the daylight.
    Before the mode of operation of the luminaire 100 according to the invention is explained in more detail with regard to the emission of daylight and artificial light, the cover 50 arranged on the underside of the housing 10 will first of all be explained in more detail. As already mentioned, this is essentially formed according to a solution described in EP 2 221 528 A2. The cover in this case has a peripheral frame 51 which is fastened by means of a screw 52 on the underside of the lamp housing 10. The frame 51 serves to hold two so-called coverings 53 and 55, which are formed by films or fabrics. Thus, these fabrics consist of a flexible material, which allows clamping into the frame 51 of the cover 50. This takes place, for example, with piping provided in the edge region of the coverings 53, 55, which cords can be hung in corresponding channels of the profile frame 51.
    Preferably, both fabrics 53 and 55 are light-scattering, so that over this dual additional control an extremely homogeneous light output over the entire surface is achieved. Further, however, the fabrics 53 and 55 are designed to additionally provide soundproofing. This can be promoted in particular by the fact that the outer or lower clothing 55 is relatively sound-permeable while, on the other hand, the inner clothing 53 facing the housing 10 has a lower sound transmission. Accordingly, sound occurring from the outside or from the bottom onto the surface can penetrate into the intermediate space between the two coverings 53, 55, but it is held captive, so to speak, and accordingly no longer reflected back. In this way, the luminaire additionally contributes to the improvement of the indoor climate, although, if necessary, the light exit area of the luminaire 100 could also be designed otherwise.
    The mode of operation of the luminaire according to the invention is shown in FIGS. 5a and 5b. In this case, FIG. 5a initially shows the case that daylight, which falls onto the luminaire 100 from the upper side, is emitted via the luminaire. It can be seen that the rays entering via the open rear side of the housing are scattered by the optical elements 25, so that a uniform, homogeneous light output is achieved, which is additionally supported by the coverings 53 and 55 of the cover 50. However, the optical elements 25 are primarily responsible for the uniform emission of daylight. The mode of operation is so good that the support elements 15 with the light sources are barely recognizable as dark stripes in the luminaire.
    If, on the other hand, no or only a very small proportion of daylight is available, artificial light emission can take place, as shown in FIG. 5b. In this case, the light is emitted primarily by the LEDs 21, with the help of the primary optics 22 again a uniform distribution of the LED light is achieved. In this case, this distribution is so efficient that no individual bright strips extending in the longitudinal direction within the luminaire 100 can be seen, but in turn the lower covering 55 of the cover 50 appears uniformly bright.
    Accordingly, it is thus possible for the light 100 according to the invention in fact to emit daylight as well as artificial light, which leads to an extremely pleasant lighting situation. As light sources for the artificial light, preferably white light LEDs are used. However, it would also be conceivable that optionally a small portion of the LEDs also emits colored light, which is then used to give the artifact a certain color mood.
