In an embodiment, the rear side of the illumination panel 1 will comprise a metal plate.
In figure 3, a side view of the illumination panel 1 is shown. In many embodiments, the illumination panel 1 will have a thickness of between 0.5 and 3 cm. In the current embodiment, the illumination panel 1 will be between 1 and 1.5 cm in thickness, but thinner may also be possible..
In figures 4-6, several views of a mounting plate 7 are shown. The illumination panel 1 together with the mounting plate here show an embodiment of an illumination device for a ceiling system. The use in a ceiling system is shown in figure 7.
In figure 4, a front side 10 of the mounting plate is shown. Here, the mounting plate has a central hole in order to allow access to the space above a ceiling system. Furthermore, such a hole 9 saves material.
The mounting plate 7 also has mounting parts 8 that engage with mounting provisions in or on the rear side of the illumination panel 1. Here, permanent magnets 8 are provided in the mounting plate 7 that attract an iron metal rear surface of the illumination panel 1. Alternatively, iron or magnetic patches may be incorporated in the rear surface of the illumination panel 1 that interact and are attracted by the mounting parts 8 in order to hold the illumination panel 1 attached to the mounting panel 7. The attachment is usually of a reversible nature, allowing the illumination panel 1 to be removed from the mounting plate. Alternatively, Velcro patches or parts or similar mounting parts 8 may be used.
The mounting plate 7 is shown from its rear or ceiling side 1 in figure 5. Here, to provide additional rigidity, the mounting plate 7 has ribs 15. In order to allow attachment of a power cord 5 to a power supply above a ceiling system, the mounting plate 7 is provided with a cable passage 14. A recessed part 13 allows positioning of the strain relief 6. In that way, the illumination panel 1 can be mounted to the mounting plate 7 with its substantially flat rear surface 4 almost against the surface 10 of the mounting plate 7. Figures 6A-bC show the indicated parts of the mounting plate in cross section, illustrating the various features that are described.
Figure 7 shows several illumination devices comprising mounting plates 7 and illumination panels 1 together mounted in a ceiling system. The ceiling system has attachment means 16, schematically indicated and here comprising rails and hooks mounting the rails. The mounting plates 7 are here carried by the rails, and rest on the rails. The mounting plate 7 as here recesses 12 that are provided with permanent magnets that are almost level with the front surface 10 of the mounting plate 7.
The illumination panel 1 and said mounting plate 7 have a functionally equal length and width. The illumination panel 1 is in figure 7 (and also in 7A) mounted out-of-register but with its sides functionally parallel to sides of said mounting panel or mounting plate 7. Here, the illumination panel 1 is mounted with two opposite sides functionally aligned with two opposite sides of said mounting panel or mounting plate
7.
In figure 7A, an illumination device comprising a mounting plate 7 and illumination panel 1 is combined with common ceiling panels 30 of the type used in a concealed ceiling. The panels hide the rail 16 (almost) completely from sight.
In figures 8-10, an alternative embodiment of the illumination device is shown.
In figure 8, a rear view or the ceiling side of an illumination device 20 is shown. In figure 1 the illumination device 20 of figure 8 is shown from its front side or illumination side.

In its front side, the illumination device has a diffusor plate 23.
In figure 10, a partial cross section of the illumination device 20 of figures 8 and 9 is shown. In the rear box part 22, lighting elements are mounted. Here, a series of light emitting diodes (LEDs) is mounted inside the rear box part 22. The same lighting elements as explained above can be applied.
The diffusor plate 23 is such that from the illumination side or front side, the illumination device provides a homogeneous, evenly illuminating area.
At its peripheral rim 26, forming a flange, the diffusor plate 23 is here attached to a peripheral rim 25 of the rear box part 22. The diffusor may be glued to the rear box part 22, or attached for instance by means of rivets, of the parts may be screwed or bolted together. Here, the diffusor plate 23 falls inside a flange surrounding the periphery of the rear box part 22. Alternatively by folding extending parts of the rear box part 22 around the sides of the diffusor plate 23 (not shown), forming a complete flange holding the diffusor plate 23 onto the rear box part 22. The flange 25 from the rear box part and the flange 26 from the diffusor 23 form a mounting flange 27 for resting an the rail 16 of the ceiling system. The mounting flange 27 may extend along two opposite sides of the illumination device, or form a peripheral mounting flange 27.
The diffusor plate 23 has a central part extending in front direction beyond the peripheral rim. In this way, the illumination device 20 can be mounted with its peripheral rim resting on ceiling system rails 16 and its central part having a surface extending into the room or building space beyond the rail 16.
In figure 11, part of a ceiling system is shown, in which several illumination devices 20 are combined. In figure 11 A, the illumination device 20 is combined with common ceiling panels 31 that have a lowered surface.
In figure 12, an alternative embodiment of an illumination device is depicted. On the rear surface of illumination panel 1, holding parts 32are mounted. These holding parts 32 may be glued, attached via screws or bolts, or in another way known to a skilled person. Alternatively, these holding parts 32 may be attached in a less permanent or even removable way, for instance using permanent magnets, or via velcro, for instance. A first holding part 32 is mounted in such a way as to provide a (in use horizontal) groove substantially parallel to a side of the illumination panel 1.
The groove extends in longitudinal direction substantially of functionally parallel to a side of the illumination panel 1. Here, the groove opening starts at a distance from the side of the illumination panel 1. It allows the ceiling system rail 16 to fall within the illumination panel 1, or in other words in use to be covered by the illumination panel 1.
At an opposite side, a holding part 32 is mounted in such a way that it provides a ledge for resting on a ceiling system rail 16, and which ledge extends beyond a side of the illumination panel 1. Usually, the illumination panel 1 is rectangular, often square.
It will also be clear that the above description and drawings are included to illustrate some embodiments of the invention, and not to limit the scope of protection. Starting from this disclosure, many more embodiments will be evident to a skilled person. These embodiments are within the scope of protection and the essence of this invention and are obvious combinations of prior art techniques and the disclosure of this patent.
