Definitions
- the invention relates to a pendant lamp with a direct one Workplace directed light component and with an indirect light component.
- the invention relates to a workplace-related pendant lamp with at least one luminaire component for direct lighting a workplace and with a further luminaire component for Indirect lighting, being indirect lighting Luminaire component provided with its longitudinal extension in the transverse direction for the orientation of the workplace and the luminaire component intended for effecting direct lighting in the area of one end related to the longitudinal extent of the Luminaire component is arranged.
- Such pendant lights are known from the prior art.
- a workstation-related pendant lamp comprises a plurality of lamps, of which at least one lamp is arranged to emit upwards to produce indirect (room) lighting. At least one other illuminant is provided for directly illuminating the workplace.
- the fluorescent lamps used are oriented parallel to one another with respect to their longitudinal extent, so that the longitudinal extent of the pendant lamp is essentially defined by the length of the fluorescent lamps used.
- such a pendant lamp can be arranged in the longitudinal or transverse direction to the workplace orientation above the workplace.
- Workplace orientation is to be understood as the orientation that runs in the direction of view of a person using the workstation. If such a workstation is, as is typically provided, an office workstation, the front edge of the desk of the office desk runs transversely to the orientation of the workstation.
- Luminaires to be attached to the workplace for example office table lamps do not need to be used, so that on the Space available in the workplace is not provided by lighting fixtures is restricted.
- the indirect light component of such a pendant lamp serves for room lighting on the one hand, but also on the other to illuminate the workplace with an indirect light component.
- Another workplace lamp is known from DE 33 01 277 A1 become, consisting essentially of an elongated Luminaire housing in which one or more, parallel to each other Fluorescent lamps are arranged.
- the longitudinal extension of the Luminaire housing and thus following the fluorescent lamp is in the middle A light outlet opening on the upper side of the lamp housing arranged, through which an upward-radiating indirect lighting is effected. Adjacent to this lighting component are in the bottom the light outlet openings in the luminaire housing are arranged, through the work area located below the work light is illuminated directly.
- the longitudinal extension of the entire Workplace lamp extends in the transverse direction for orientation of the Workplace, such as a desk, and thus in terms of width of the workplace parallel to this.
- the middle work area is largely free of glare. Since the workplace lamp is usually not wider than that Workplace, for example a desk, and to provide the necessary light for direct lighting the light outlet openings on the underside the portion needs a certain length of the luminaire used for indirect lighting smaller than the proportion used for direct lighting. With such a workplace lamp available on the market is the one Luminaire component that does not emit downwards, about 50 cm long.
- a usual mounting height of the lamp means that the glare-free Space in the workplace is only about the size of one A4 sheet. All other work areas are subject to a reflective glare, even if using appropriate grids a light control is provided in the light exit area.
- a further workplace lamp is known, the also has an elongated luminaire housing in which several arranged independently controllable fluorescent lamps are. It is envisaged that part of the fluorescent lamps on their entire length downwards and another part radiating upwards are arranged. With this workplace lamp, the entire Length of the lamp both indirect and direct lighting.
- Such a workplace lamp is usually related to one Workplace, for example a desk arranged in such a way that the longitudinal extent of the lamp housing parallel to the width of the workplace and thus in the transverse direction for orientation is arranged. Only if this workplace lamp is in the edge area is located next to a workplace, then there are no glare Areas on the surface of the workplace.
- the invention lies on the basis of this prior art discussed therefore based on the task of a generic Continuing to educate pendant lamp in such a way that with this a workplace can be directly illuminated without glare.
- the pendant lamp according to the invention is characterized in that the Longitudinal extension of the lamp essentially through the longitudinal extent of the luminaire component intended for indirect lighting is determined.
- a lamp thus extends over the entire Width of a desk, then is essentially above this entire length no luminaire component through which the desk surface and thus the workplace is directly illuminated.
- Those Luminaire components for direct lighting of the workplace are provided, are located with their longitudinal extension in the transverse direction for the longitudinal extension of those lamp components that are indirect Effect lighting. The width of these lighting components related The width of a workplace can therefore be very small his.
- the lighting component (s) for direct lighting are therefore at a relatively large distance from the center of the workplace, so that the light rays emitted by this luminaire component in a relatively small angle of incidence on the work surface to be illuminated hit. As a result, essentially the entire work surface is glare-free.
- pendant lamp also expediently for illuminating two ends adjacent jobs are used so that a single pendant lamp for glare-free lighting from two workplaces can be used.
- Illuminants for providing indirect lighting can, for example Fluorescent lamps are used, the length of which the longitudinal extent of this component of the lamp follows, so that this also arranged transversely to orient the workplace are.
- Illuminants for providing indirect lighting can, for example Fluorescent lamps are used, the length of which the longitudinal extent of this component of the lamp follows, so that this also arranged transversely to orient the workplace are.
- light bulbs, Halogen incandescent or fluorescent lamps can be used. in the the latter case is the orientation when using fluorescent lamps of fluorescent lamps for direct lighting of the workplace expediently in the longitudinal direction for orientation of the workplace arranged.
- the side by side arrangement expediently provided the luminaire components also serve to reduce the overall height the pendant lamp, so that this is exclusively due to the height of the illuminants used and the reflector arrangements used is determined.
- An advantageous pendant lamp used for direct workplace lighting two lamp components, one on each End of the luminaire component intended for indirect lighting is arranged.
- the workplace is on the side illuminated from both sides, ensuring that the user is in its intended place in the glare-free room.
- an arrangement consisting of such a pendant lamp and a workplace for example an office desk Demand for anti-glare workplace lighting, for example ensure that the longitudinal extension of the indirect Lighting provided component is larger than that illuminating core area of the workplace in its transverse direction Workplace orientation.
- a functional and extremely elegant Pendant lamp with only a very low height can for example be formed by providing a rectangular frame, the Longitudinal struts of the frame through those provided for indirect lighting Light components and the cross struts of the frame the lighting components intended for direct lighting of the workplace are formed.
- To avoid direct glare from a Workplace users can use it to illuminate the workplace directly provided lighting components on the underside grid, prismatic lenses or similar light-directing means.
- Such Glare can also be achieved by using, for example achieve narrow-beam asymmetrical reflectors.
- the use of independent lamps for direct or indirect The proportion of light in the pendant luminaire enables individual requirements appropriate lighting of a workplace or work surface including lighting of the surrounding room. Also a light-integrated daylight and absence dependent Light control can be used.
- a work station arrangement 1 comprises an office desk 2, the Transverse side represents the view shown in Figure 1, and one of one Ceiling 3 suspended pendant lamp 4.
- the pendant lamp 4 includes a two-element lighting component 5, 5 'in the illuminants radiating upwards are arranged.
- Figure 1 is only the luminaire component 5 can be seen.
- the lamp components 5, 5 ' are used for indirect lighting of the office space and the office desk 2. With the dashed lines up is the radiation cone of the lamp component 5 indicated.
- illuminants are in the Luminaire component 5 fluorescent lamps used.
- the longitudinal extension the lamp component 5 is larger than the core area of the the office desk 2 shown workplace.
- Luminaire components 5, 5 'each have a luminaire component 6, 7 arranged, which lighting components 6, 7 for direct lighting of the Office desks 2 and thus are provided radiating downwards.
- the lighting of the office desk 2 through these lighting components 6, 7 thus takes place from a lateral direction, so that the most of the office desk 2 related to a workplace user, who sits in front of the illustrated transverse side of the office desk 2, is glare-free illuminated.
- the emitted light cone of the lamp components 6, 7 is also shown by broken lines downwards.
- the Luminaire component 5 determines the longitudinal extent of the pendant lamp 4 determined.
- the immediately adjacent to the lamp component 5 Luminaire components 6, 7 increase the longitudinal extent of the Pendant lamp 4 only slightly. Because of the juxtaposition the lamp components 5, 5 'and 6 and 7 is the overall height of the Pendant lamp 4 only very low.
- the Figure 2 shows the further structure of the pendant lamp 4.
- the pendant lamp 4 is a by its lamp components 5, 5 'and 6, 7 Frame 8 designed to form. It is envisaged that the two Luminaire components 5, 5 'the longitudinal struts and the luminaire components 6, 7 represent the cross struts of the frame 8.
- a luminaire component 5 In a luminaire component 5, 5 'is a fluorescent lamp 9 in front of a reflector element 10 arranged radiating upwards.
- the lighting components 6, 7 for direct lighting of the office desk 2 are radiating downwards provided so that from the view of Figure 2 only the Back of the reflector elements 11 used in the illustrated Exemplary embodiment as narrow-beam asymmetrical reflectors are trained, are recognizable.
- the underside of the lamp components 6, 7 is in the area of the light exit each covered by a light-guiding prismatic lens 12, 13. Through the prismatic discs 12, 13, the light radiation in the desired light cone shown to Figure 1 held.
- the reflectors are of the lamp components 5, 5 'partially transparent, so that with a low luminance also a radiation downwards to the office desk.
- This downward luminance serves only as an aesthetic emphasis on the lamp 4 and not the direct workplace lighting.
- the radiated luminance is accordingly so small that a direct one and especially an indirect one Glare to the workplace user does not occur.
