Definitions

  • the invention relates to the combination of a table with table frame and table top and at least one luminaire with variable luminous intensity, wherein the table top is designed to be variable in height, and wherein the light intensity of the lamp for illuminating the table top in dependence on their height position is set so that the illuminance on Location of the tabletop is substantially consistent.
  • the luminaire In the case of tables with a table frame and tabletop, it is important, especially in connection with office workstations, to provide perfect lighting. In fact, the luminaire should ensure that the table top is illuminated as evenly as possible and that dazzling effects with regard to screens placed there are avoided. Alternatively or additionally, the luminaire is often also expected to have room lighting - in addition to the illumination of the table top.
  • LED-based lighting system which has a modular structure.
  • the familiar LED lighting system can be used, among other things, as workplace lighting in combination with a table with table frame and table top.
  • the table top is designed to be height adjustable.
  • the lamp is connected to the table frame.
  • the table frame consists of at least two each predominantly vertically oriented table columns and associated feet together.
  • the lamp is connected to a post.
  • a work lamp As part of the pre-publication DE 20 2012 010 025 U1 a work lamp is described, whose illuminance can be regulated in individual dependence on the height of the workstation. As a result, the working surface of the workplace can always be illuminated with the same and pre-set illuminance at any workplace height.
  • the invention is based on the technical problem of further developing such a combination of a table and at least one luminaire with variable luminous intensity so that the illumination and the arrangement of the tabletop are optimized.
  • a combination of a table with table frame and table top and at least one luminaire with variable luminous intensity with the features of claim 1 is provided.
  • the lamp is arranged stationarily above the table top.
  • the two table columns can be coupled together via a connecting strut.
  • the table column for receiving the foot of the lamp is arranged substantially parallel to the adjacent table column of the table frame.
  • the two table columns coupled together via the connecting strut define the table frame. Telescoping guide rails, which carry the height-adjustable table top, are respectively received in the two table columns.
  • the table or office table and the lamp in question form a unit. In most cases, even at this point a unit is preferred, in which the lamp is connected to the table.
  • the lamp ensures the illumination of the table top. Since the table top is designed to be variable in height, it depends on the invention to control the different height positions of the table top lighting technology. For this purpose, the invention proposes that the light intensity for the illumination of the table top is set substantially constant, regardless of the height position of the table top.
  • the luminous intensity of the lamp is reduced, for example, in the highest position table top compared to the case that the table top is in its lowest position. That is, in the highest position of the table top is worked with low light intensity of the lamp. In the lowest position of the tabletop, however, the light intensity is high.
  • the illuminance at the location of the table top that is to say the quotient of light intensity and the distance (to the square)
  • the illuminance generally refers to the specific light emission and is given as the quotient of the luminous intensity of a mostly punctiform light source and the square of the distance.
  • the illuminance is measured in lumens per square meter, which corresponds to the unit lux.
  • the illuminance can also be measured in candela.
  • the invention provides that the illuminance (measured in lux) of the lamp for illuminating the table top is set substantially constant at the location of the table top, regardless of the height position of the table top.
  • the bottom line is that the fixed and arranged above the table top light changes their distance from the table top, because the table top is designed to be variable in height.
  • the luminous intensity of the luminaire is adjusted so that the illuminance at the location of the table top is substantially constant. That is, depending on the height position of the table top, the light intensity of the lamp is adjusted in each case, so that the illuminance at the location of the table top is substantially consistent and, of course, meets legal requirements. It is therefore to be expected with constant light conditions, regardless of whether the table top occupies its highest or lowest position.
  • the main benefits are the main benefits.
  • a sensor is provided as a rule to detect the height position of the table top and / or a distance of the lamp from the table top.
  • the luminaire is usually placed in a stationary manner above the table top and connected in total to the table or the table frame. Since the table top can change its height position, consequently varies also the distance of the lamp from the table top. This distance is measured with the help of the sensor.
  • the senor may, for example, be a displacement sensor which measures the travel of the table top relative to the stationary table frame.
  • the luminaire can also be equipped with a distance sensor which measures the distance of the luminaire from the tabletop below it.
  • the sensor is advantageously connected to a control unit for adjusting the light intensity of the lamp. If the distance between the luminaire and the table top decreases, the luminous intensity of the luminaire is regularly reduced. However, if the distance increases, the light intensity is increased accordingly.
  • the lamp is usually equipped with a plurality of sources of illumination.
  • These illumination sources are typically LEDs and in particular white light LEDs.
  • the individual illumination sources are arranged in a planar manner and define, for example, a rectangular luminous area.
  • the illumination source is often still the radiation side of the illumination source equipped with a diffuse light scattering body.
  • the white light emanating from the illumination sources diffuses diffusely and ensures a uniform light impression on the tabletop below.
  • This light-scattering body can be equipped with openings through which the individual illumination sources emit essentially unhindered. The light emanating from the illumination sources and not emitted by the opening may additionally be emitted diffusely in this context.
  • the design is usually still made so that part of the diffused light is emitted to the rear, that is, away from the table top in the room. In this way, the light ensures that not only the table top is illuminated directly, but at the same time an indirect room lighting takes place.
  • the lamp can be found fixed above the height-adjustable table top.
  • the lamp is usually located above the center of the table top.
  • the light is usually connected to a post.
  • the post is formed in two parts with one foot and a contrast arm angled.
  • the foot of the post is taken up in a table pillar.
  • the lamp is connected to the angled arm end.
  • the foot is detachably inserted into the column and can be anchored in the column.
  • the foot can also be anchored to the table pillar in different height positions.
  • the light can be changed in their position above the table top and easily adapted to the particular circumstances.
  • the luminaire can therefore be fixed above the table top.
  • a variable position of the light above the table top is possible.
  • the table frame for the height-adjustable table regularly consists of two table columns, which are interconnected. Inside the respectively usually vertically arranged table columns can each telescope guide rails, which in turn carry the table top, such as this in detail in the introductory already described DE 10 012 109 469 A1 is treated.
  • the combination of a table with table frame and table top and at least one luminaire with variable light intensity is provided, which for the first time consistently consistent lighting conditions at the location of the height-adjustable table top is available. That is, an operator encounters consistent lighting conditions, regardless of whether the tabletop is in its highest or lowest position. As a result, special ergonomic advantages are achieved and is expressly counteracted fatigue in the workplace.
  • the attachment of the lamp to the table frame ensures defined conditions. In fact, in this way it can be ensured that the luminaire is arranged, for example, centrally above the table top and maintains its position. This applies both in the event that the lamp is placed stationary above the table top as well as when the lamp undergoes a change in height above the table top.
  • the lamp itself is taken up with her foot in a table column, which can be a table column of the table frame.
  • a table column which can be a table column of the table frame.
  • a separate - third - table column is realized.
  • the lamp can be set to save space on the table frame, because the table column for receiving her foot and the adjacent table column of the table frame can be connected together.
  • the foot can be integrated into the table and may pass through an opening in the tabletop.
  • a compact and shapely structure is achieved.
  • a combination of a table 1 and a lamp 2 is shown.
  • the luminaire 2 is arranged stationarily above a table top 3.
  • the lamp 2 is connected to a table frame 4, 5, 6.
  • the table frame 4, 5, 6 is composed of two respectively predominantly vertically oriented table columns 4 and associated feet 5 together.
  • the two table columns 4 of the table frame 4, 5, 6 are coupled to each other via a connecting strut 6.
  • third pillar column 4 on one side of the table frame 4, 5, 6 is added, as the figures make clear.
  • the third pillar column 4 extends predominantly parallel to the adjacent pillar column 4 of the table frame 4, 5, 6.
  • Both mutually parallel and adjacent pillars 4 use a common foot 5.
  • both pillars 4 are coupled together by, for example, cross struts, as shown by FIGS. 1 and 2 becomes clear.
  • the luminaire 2 has a variable light intensity (measured in lumens). In this way, the light emission or light intensity can be changed at the location of the table top 3.
  • the luminaire 2 is arranged in a stationary manner above the height-adjustable tabletop 3. In most cases, the lamp 2 is located above or in the region of a center of the table top. 3
  • the luminous intensity of the luminaire 2 for illuminating the tabletop 3 is now set as a function of the height position of the tabletop 3 so that the illuminance at the location of the tabletop 3 is substantially constant. That is, the illuminance at the location of the table top 3 is approximately constant, both when the table top 3 is in its highest position (shown on the left) and when the lowest position is occupied (shown on the right). As a result, constant light conditions at the location of the table top 3 are achieved, regardless of their height position relative to the table frame 4, 5, 6.
  • the light intensity of the lamp 2 must be adjusted.
  • the luminous intensity of the luminaire 2 tends to be lower in the highest position than in the lowest position because the luminous intensity represents the quotient of the luminous intensity and the square of the distance. If, for example, the distance A is doubled, the luminous intensity must be set four times greater in order to keep the illuminance at the location of the tabletop 3 constant.
  • a sensor 8 is additionally provided. With the help of the sensor 8 in or on the lamp 2, the distance A of the lamp 2 is detected by the table top 3.
  • the sensor 8 may be a distance sensor based on ultrasound and / or laser, for example.
  • the sensor 8 in question is connected to a merely indicated control unit 9. With the help of the control unit 9, the light intensity of the lamp 2 is changed.
  • the lamp 2 is connected to a post 10, 11.
  • the post 10, 11 is formed in two parts with a foot 10 and an arm 11 developed in contrast thereto.

  • the angled arm 11 carries the end of the lamp 2.
  • the already mentioned control unit 9 may be arranged protected.
  • the sensor 8 is connected via a running in the interior of the post 10, 11 connecting line to the control unit 9, so that any damage to the sensor 8 as well as the control unit 9 and its connection line can be de facto excluded. In addition, a particularly appealing appearance is provided.
  • the luminaire 2 itself is usually equipped with a plurality of illumination sources.
  • the illumination sources are arranged flat.
  • the plurality of illumination sources define a rectangular luminous surface 12.
  • a diffusely light-scattering body may be provided on the radiation side of the individual illumination sources.
  • the light 2 provides not only for a direct illumination of the table top 3, but can additionally also generate light emitted indirectly in the room. Of course, this is only an example and is not mandatory.

On the other hand, if the tabletop 3 wanders to its lowest position, the luminous intensity of the luminaire 2 is increased.
  • the invention ensures that the illuminance, ie the quotient of the light intensity and the square of the distance A, in the range the table top 3 is set substantially constant. This is to be expected in a standing as well as sedentary activity with constant lighting conditions and thus any signs of fatigue of the operating personnel is prevented.
