• Figure 1 is a cross sectional view of a first embodiment of an electronic structure according to the invention.
• the electronic structure comprises a transparent or at least quasi-transparent panel 1 and a matrix of at least one module(s) 11. For clarity, only one module is represented on figure 1.
• the electronic structure is for instance a luminaire (or a decorative device) wich can be attached to the roof of a room and which illuminates the space under it thanks to the module(s).
• at least one module comprises at least one light emitting element (such as a LED and/or an OLED and/or a bulb and/or a discharge tube) and the electronic structure is a luminaire which can be used to illuminate the space.
• the at least one light emitting element can be a packaged LED (such as surface mount type LED or ampoule type LED) or a die LED, an RGB LED (for Red Blue Green LED) or a phosphor LED.
• the panel 1 comprises two conductive paths 2a, 2b (which can be chosen to be transparent : for instance conductive coatings such as fluorine-doped tin dioxide (SnO 2 IF) or Indium Tin Oxide (ITO) coatings or which can be chosen to be very conductive : for instance silver paste deposited by a serigraphy technique) and two magnetic elements 3a, 3b.
• conductive paths 2a, 2b and the magnetic elements 3a, 3b of the panel 1 are arranged on a transparent substrate layer 7 for instance made of glass.
• the magnetic elements 3a, 3b are thereby partially arranged on the conductive paths 2a, 2b.
• Figure 1 shows that the magnetic elements 3 a, 3b are arranged at least essentially in the plane of the conductive paths 2a, 2b or rather of the conductive paths layer 2a, 2b.
• the conductive paths 2a, 2b extend to two opposite edges of the panel 1. In this way, the conductive paths 2a, 2b can be electrically connected to a power supply and/or control device (not illustrated).
• the panel 1 is a composite element, which addition- ally comprises a transparent or at least quasi transparent cover layer 4, for instance made of glass or metal (such as steel or aluminium or any other metal) or plastic, having a matrix of through openings 5 (such as holes realized in the glass cover layer), and a linking layer 6.
• a transparent or at least quasi transparent cover layer 4 for instance made of glass or metal (such as steel or aluminium or any other metal) or plastic, having a matrix of through openings 5 (such as holes realized in the glass cover layer), and a linking layer 6.
• the linking layer 6 for instance a plastic interlayer (e.g. PVB for Poly Vynil Butyral), is arranged on the conductive paths layer 2a, 2b so that the magnetic elements 3 a, 3b are only partially covered by the linking layer 6.
• the cover layer 4 is again arranged on the linking layer 6, whereas the through opening is positioned so that the magnetic elements 3a, 3b are at least partially accessible via a through opening 5 in the cover layer 4.
• the module 11 can be inserted through the through opening 5 in the cover layer 4 and be placed on the magnetic elements 3a, 3b of the panel 1.
• the module 11 comprises an electronic component 12, two magnetic elements 13a, 13b, a support 14 and a radiator 15, for example the radiator FISCHER ELEKTRONIK - ICK BGA 23x23.
• the magnetic elements 13a, 13b are both electrically connected to the electronic component 12 via a support 14.
• the magnets are arranged on one side of the support 14. On this side of the support 14 also the electronic component 12, for example a light emitting diode, is arranged.
• the radiator 15 is thereby arranged on the side of the support 14, which is opposite to the side on which the electronic component 12 and the magnetic elements 13a, 13b are arranged.
• the electronic component 12 can for example be a light emitting diode, for instance a diode with the reference CL-L220-HC16N-A from Citizen Electronics. In that case, the radiator 15 allows to dissipate heat generated by the electronic component 12.
• the cover layer is made of a thermally conductive material (such as steel, stainless steel, aluminium...) and the at least one module 11 is in thermal contact the cover layer (a thermal connection or junction is created between the at least one module and the cover layer).
• the support 14 is also made of thermally conductive material (such as steel, stainless steel, aluminium%) and the surface of the support is chosen bigger than the through opening 5 in the cover layer 4 (for example the through opening 5 has a 30mm diameter and the support has a 30mm diameter). Thanks to the thermal junction between the support 14 and the cover layer 4, the cover layer acts then as a surface radiator, allowing to dissipate heat generated by the electronic compo- nent 12 (and then, for instance; to use higher power/currents to drive the electronic component, e.g. to implement high luminous flux LEDs as electronic components). It further allows, if necessary, not to use the radiator 15 in the module 11.
• the thermal contact can be realized, for example, simply by contact, or by using spring metal parts ("rondelle Belleville").
• FIG 1 illustrates, that the module 11 is, mechanically and electrically attached to the panel
• I 1 are magnets
• the corresponding magnetic elements 3a, 3b of the panel 1 are elements formed of a material, which is magnetically attractable by a magnet
• some of the magnetic elements 13a, 13b of the modules 11 are elements formed of a material, which is magnetically attractable by a magnet
• the corresponding magnetic elements 3 a, 3b of the panel 1 are magnets.
• a user can pull on the module 11 by exerting a force that at least compensates the magnetic attraction between the magnetic elements 13a, 13b of the module 11 and the magnetic elements 3a, 3b of the panel 1.
• the number of module(s) 11, pair of conductive paths layer 2a, 2b, pair of the magnetic elements 3a, 3b and opening(s) 5 can be chosen from one to an unspecified number.
• the electronic structure according to the invention can comprise a number of pair of conduc- tive paths layer 2a, 2b, pair of the magnetic elements 3a, 3b and opening(s) 5 that is different to the number of modules.
• At least one module 11 of the panel can be detached from its position on the panel : to be attached at another position of the panel or to be replaced by another module having a different color and/or color temperature and/or lighting profile and/or intensity and/or function (such as lighting, detection of person, detection of temperature, ...) and/or performance(s), in order to change at least one of the : color color temperature,
• LED(s) performance(s) such as lighting intensity, temperature stability
• the panel of the electronic structure do not comprise the linking layer 6 and the cover layer 4.
• the module(s) 11 are directly placed on the magnetic elements 3a, 3b of the panel 1.
• Figure 2 is a cross sectional view of a second embodiment of an electronic structure according to the invention.
• the second embodiment thereby differs from the first embodiment in that the transparent substrate layer 7 is a double glazing.
• the transparent substrate layer 7 is a double glazing.
• Figure 3 is a cross sectional view of the module shown in Figures 1 and 2.
• Figure 4 is a cross sectional view of the panel shown in Figure 1.
• Figure 5 is a cross sectional view of a third embodiment of an electronic structure according to the invention, which is a lighting device comprising several lighting modules 11 (not illustrated) that can be added and removed at the will of the user.
• the panel is a composite element and comprises a cover layer having four through openings 5, a linking layer (not illustrated), a transparent substrate layer 7, several conductive paths 3, 3' forming current feeder circuits and eight magnetic elements, symbolized by the rough shaded rectangles.
• the eight magnetic elements (rough shaded rectangles) are electrically connected to the conductive paths 3, 3'.
• the different shadings 3, 3' thereby symbolize different applicable polarities, whereas for example 3 can be the negative terminal and 3 ' can be the positive terminal.
• Figure 5 illustrates that the magnetic elements (rough shaded rectangles) are positioned so that they are each accessible via one through opening 5 in the cover layer 4.
• four modules 11 are inserted and mechanically and electrically attached in a detachable manner to the panel by magnetic attraction between their magnetic elements (not illustrated) and the magnetic elements (rough shaded rectangles) of the panel.
• the four modules 11 comprise each one light emitting device as electronic component.
• the four modules 11 are connected in parallel.
• a power supply can thereby be voltage-controlled.
• the addition and removal of modules 11 from the current feeder circuits 3, 3' shown in Figure 5 does not disturb the functioning of other modules 11.
• Figures 6a and 6b are a cross sectional views of a forth embodiment of an electronic structure according to the invention, in which one module 16 contains a function, which is different to the function of the other modules 11, for example lighting modules 11.
• the differing module 16 can comprise an infra-red sensor module which allows to communicate with a remote control and which allows to dim the intensity of the lighting modules 11.
• the differing module 6 can comprise an infra-red receiver, a decoder, a microcontroller and a switch as electronic components.
• the infra-red receiver can receive signals from an adapted remote control, the signals can then be decoded by the decoder and sent to the microcontroller that actuates a switch, for example by adapting the cycle ratio of a con- trollable switch, for instance by increasing the cycle ratio - and thereby the average current - when a higher power is requested and by decreasing the cycle ratio- and thereby the average current - when a reduction in power is requested.
• FIGs 6a and 6b show that the forth embodiment differs from the third embodiment shown in Figure 5 in that one lighting module 11 is replaced by a module 16 comprising n infra-red receiver, a decoder, a microcontroller and a switch as electronic components, whereas the current feeder circuits formed by the conductive paths 3, 3', 3" is adapted.
• the module 16 adjusts the period during which it creates short circuit 3" between the positive 3 and the negative 3' terminal, whereas the lighting modules 11 are short- circuited and extinct (see Figure 6a) and the period during which the diodes are fed (see Figure 6a)
