  • the holding structure 13 is formed for example in U shape with an upper fold 131 and a lower fold 132.
  • the lower fold 132 is engaged with the upwardly opened protrusion element 71 at the bottom side of the lighting module 20, whereas the upper fold 131 is locked by a hook 91 connected to a spring-mounted lever 98 of the clamping element 9 projecting from the lighting module 20.
  • the lighting unit 6 is provided with protrusions 61 , which interlock with the L-shaped frame 8.
  • FIG. 4 shows an enlarged clamping element 9.
  • the clamping element 9 is configured to mount or release the lighting module 20 by applying a manually applied force, particularly a tensile force in this exemplary embodiment.
  • the clamping element 9 may comprise a pivotable lever-spring system, a cable-pull system or the like. In the present embodiment, a pivotable lever-spring system is applied.
  • the clamping element 9 allows a toolfree assembling and disassembling of the lighting module 20 along the holding structure 13, simultaneously it prevents an unintentional release of the lighting module 20.
  • the lever 98 with the hook 91 is rotatably mounted about a rotation axis 92 formed in the flange plate 7.
  • the lever 98 is tiltable about a rotation axis 92 against the upward force of a compression spring 93 (i.e. in y-axis direction) and accordingly releases the hook 91 form the upper fold 131 of the holding structure 13.
  • the upper end of the compression spring 93 engages with the lever 98 and the lower end of a compression spring 93 engages with a guide groove 94 and is movable therein in z-axis direction.
  • a linking element 97 formed on the lever 98 is engaged.
  • FIGS 5 and 6 show schematically two exemplary embodiments of an arrangement of a lighting system.
  • the lighting system comprises an elongated holding structure 13 and a plurality of lighting modules 20.
  • the lighting modules 20 are each releasably connected with at least one of a group o a power line 1 , a data line 2 and a cooling line 3, 4.
  • the lighting system further comprises a control unit (not shown) controlling each lighting module 20 independently and/or all, a row or an array of lighting modules 20 together.
  • the lighting modules 20 are positioned apart from each other.
  • the plurality of lighting modules 20 are arranged spaced apart from each other with different distances or intervals along the holding structure 13. Such a configuration is applicable over several conveyor belts with different applications (e.g. laboratory experiments with different light intensities).
  • the lighting modules 20 are arranged adjacent to each other and particularly laterally engaging another along the elongated holding structure 13.
  • the flange plate 7 and the spring-mounted clamping elements 9 may allow the lighting modules 20 to slideably move and be toolfreely assembled/disassembled along the holding structure 13.
  • the lighting system 20 may comprise a plurality of elongated structures 13 arranged next to each other. Due to its narrow elongated structure, the holding structure 13 allows a modular arrangement of the lighting system 20 as wide as a format width of the substrate to be irradiated.

Abstract

L'invention concerne un module et un système d'éclairage. Le module d'éclairage comprend une unité d'éclairage, une unité multimédia et une unité de fixation. L'unité d'éclairage est disposée au niveau d'une première surface du module d'éclairage et l'unité multimédia est disposée au niveau d'une deuxième surface du module d'éclairage opposée à la première surface. En outre, l'unité de fixation est disposée au niveau d'une troisième surface du module d'éclairage reliant les première et deuxième surfaces. L'unité d'éclairage est configurée pour fournir une irradiation pour sécher ou durcir un substrat. L'unité multimédia est configurée pour fournir des supports à l'unité d'éclairage ou à partir de celle-ci. L'unité de fixation est configurée pour être couplée mécaniquement à une structure de support allongée pour positionner en continu le module d'éclairage le long de la structure de support allongée et pour fixer de manière amovible le module d'éclairage à la structure de support. En outre, le système d'éclairage comprend au moins un ou au moins deux modules d'éclairage et une structure de maintien allongée.
