Description

ACOUSTIC CEILING PANEL AND LIGHTING

The present invention relates to an illuminating and acoustic ceiling panel.

In the fields of architecture and interior design, it is conventional to use panels to cover the ceiling of a room. These elements can have an aesthetic function. They can also be used to actively modify the properties of the part, in particular its acoustic properties, as is the case for example with the fiberglass panels SOLO ™ or FOCUS ™ marketed by the company ECOPHON.

For this purpose, the object of the invention is to add a new lighting functionality to an acoustic ceiling panel.

For this purpose, the subject of the present invention is an acoustic and illuminating ceiling panel comprising a layer of acoustic absorbing material, the layer comprising an internal main face intended to be directed towards the interior of the room, and light sources on the internal face possibly covered by a veil and / or coated with a paint. In addition, said light sources comprise organic light-emitting diode modules called OLED modules with preferably a luminous efficiency greater than or equal to 60 Im / W.

In the acoustic and illuminating ceiling panel according to the invention, the number and the size of the OLED modules are preferably adapted so that the ceiling panel provides a sound absorption coefficient a _w greater than or equal to 0.7 and preferably the panel complies with class A according to EN ISO 1654.

In the context of the invention, the sound absorption coefficient of an element, which is defined as the ratio of the sound energy absorbed by the element to the sound energy incident on the element, is measured from preferably according to the international standard EN ISO 354.

The panel according to the invention then combines the lighting and acoustic correction features: the size and arrangement of the OLEDs participate in broadcasting the sound wave in the frequencies of the voice. The invention allows an alternating and homogeneous distribution of the acoustic absorbers: there is no areas where acoustics are locally bad due to the presence of fixtures

Many variations are possible regarding the distribution of OLEDs within a panel, and the distribution of panels within the ceiling. We are particularly interested in configurations that can reach 500 lux (level of lighting required by the standard at a work surface), 300 lux (circulation zones) or 800 lux (precision tasks). Thus, one embodiment (9 OLED of luminance at 3000cd / m ² of 100 (mm) x 100 (mm) per panel, and 40% of coverage rate of the ceiling) is one of the configurations making it possible to achieve a working illuminance. 500 lux.

In traffic areas, the same panel can be used (still 9 luminance OLED 3000 cd / m ² 100 (mm) x 100 (mm) per panel according to the invention), this time lowering the coverage rate of the ceiling between 20 and 30%: an illumination of 300 lux is reached.

If, on the contrary, it is preferable, for aesthetic reasons, to keep the same coverage rate in panels, the panel equipped with 5 to 6 OLED 100 (mm) x 100 (mm) luminance 3000cd / m ² with a coverage ratio of 40% achieves an illumination of 300 lux.

Finally, there are different models of OLED: their size and luminance may vary from one manufacturer to another. It is therefore also possible to play on the type of integrated OLED to achieve a particular stylistic effect, or further improve the acoustic performance. The preference is for small, well-distributed units. From an optical performance point of view, a design based on 9 OLEDs of 100 (mm) x100 (mm) and luminance of 3000cd / m ² per panel (panel) is equivalent to 4 OLEDs of 150 (mm) x 150 (mm) ) at 3000cd / m ² per panel or 36 OLEDs of 50 (mm) x50 (mm) luminance at 3000cd / m ² per panel

The outer face of the panel according to the invention may be covered with an acoustic veil or with a thickness of acoustic material, and thus provide acoustic correction functionality on the rear face.

In one embodiment, an illumination of 500 lux is generated in a room (typical height 280 cm) at the level of the worktop (typical height 80 cm). For this we realize a paving of ceiling panels of 600 (mm) x600 (nnnn), of which 40% are panels according to the invention equipped with 9 OLED light sources (dimensions 10 (mm) x 100 (mm), luminance 3000cd / m ² , flow 75 Im). From a practical point of view, LG Chem's OLED N6SA40 sources (100 (mm) x 100 (mm), flow 75lm, 3000cd / m ² ) are used, for example.

According to an advantageous embodiment, the OLED modules are in contact with the corners only or preferably are spaced from each other.

In a preferred embodiment, the cumulative coverage ratio of said OLED modules is at most 30%, in particular at most 26% and preferably at least 10%.

OLED modules can be evenly distributed on the inside.

OLED modules advantageously have a luminance of at least 2500 Cd / m ^2, especially at least 3000 Cd / m ² or even at least 3500 Cd / m ² and an active surface of at least 0.02 m ² and at plus 0.29m ² , better not more than 0.20m ² and even not more than 0.10m ² and preferably the number of said OLED modules on the panel is at least 5 and not more than 50, preferably at most 20 or even 10.

According to one embodiment, the panel comprises a first series of OLED modules, in particular at most 10 or even at most 6 OLED modules, and a second series of OLED modules with a smaller active area, in particular at least 30% or even at least 50% more. small, including at most 10 or even more than 6 OLED modules of the second series.

On the inner face may further be arranged a plurality of LED said spaced apart inorganic light emitting diodes and / or one or more other electronic components, including sensors selected from one or more of the following: light, infrared, pressure, temperature, humidity , sound, air quality, or any other connected object. In one embodiment, the inner face comprises a textile (woven or nonwoven, but preferably a fabric) carrying electrically conductive wires (preferably metal, especially of a diameter of at most 1 mm) of low voltage power supply, including at most 50V, said OLED modules and any LEDs and / or one of the other electronic components including sensors selected from one or more of the following: light, infrared, pressure, temperature, humidity, sound, air quality, and other connected object.

Said OLED modules being on said textile in electrical contact with the electroconductive wires, they are electrically powered by surface contact.

The textile is particularly permeable to sound waves.

In particular the electroconductive son can be reported on the textile and embroidered or seamed (or sutured) on the textile, said OLED modules being on said textile in electrical contact with the electroconductive wires.

The textile preferably extends over all or part of the edge of the panel to bring electrical conduction to the edge of the panel.

The electrically conductive yarns may be covered in whole or in part by additional textile threads, in particular embroidery or sewn yarns, the textile yarns being able to form winding or coiling around the electroconductive yarns, the stitching yarn passing through the textile support at each point.

In a particular embodiment, the textile comprises at least one reinforcing zone and / or a positioning mark of one of said OLED modules and any LED (s) and / or of one or more other electronic components, in particular selected sensors. among one or more of the following: light, infra red, pressure, temperature, humidity, sound, air quality, and any other connected object. We can have as many references as components.

The panel may advantageously comprise a first zone of at least two electrical contacts on a first edge of the inner face and extending over a first edge of the panel, in particular the electrical contacts are on said textile which protrudes over all or part of the first edge, and preferably it comprises other zones of at least two electrical contacts on one or all other edges of the inner face and extending over (one or) other edges of the panel.

In a particular embodiment, the panel comprises at least one reinforcing zone and / or a positioning mark of one of said OLED modules. The panel may comprise an acoustic surfacing or not, preferably an acoustic surfacing, in particular a web on the so-called outer face opposite the internal face.

The invention also relates to an acoustic ceiling comprising acoustic ceiling panels and lighting according to one of the preceding panel claims, including providing illumination of at least 300lux and at most 900lux

In a ceiling according to the invention, acoustic panels (illuminant or not) are generally supported by a frame including metal. For example, the frame may be composed of inverted T-sections, and the panels rest with their internal face on the horizontal (bar) portion of the T. The panels are for example disjoint (spaced songs). Alternatively, the panels may each have a notch formed along the edge and the panels engage on the horizontal bar of the T, which is received in the notch in the thickness of the panel. This embodiment makes it possible to conceal all or part of the frame, in particular metal (so-called hidden frame assembly), and provides an aesthetic rendering of better quality. And in this case, the edges of the adjacent panels can be in contact (direct or via electrical contacts as detailed next etc).

The subject of the invention is also an acoustic ceiling comprising a plurality of acoustic ceiling panels, in particular in a region of the ceiling defined by at least 9 panels or even on the entire ceiling, it comprises acoustic ceiling panels and lighting according to the invention.

In one embodiment of the acoustic ceiling, two adjacent and disjoint panels (including at least one or both illuminating as described above) have on their respective edges facing each other () with electrical contacts which are in electrical connection with a frame (in particular metal) possibly electrically isolated and having an electroconductive zone oriented external face capable of electrically interconnecting said acoustic panels. Indeed, the acoustic panels can be supported by said frame. For example, the framework may be composed of inverse T-sections, and the two panels rest with their internal face on the horizontal part of the T. The two disjoint panels may have a notch along the edge and the panels engaged on the horizontal bar of the T, which is received in the notches in the thickness of the panels. This embodiment makes it possible to conceal all or part of the framework

The invention also relates to an acoustic ceiling comprising a plurality of acoustic ceiling panels (in particular disjoint or in contact with the edges), especially in a so-called reference region of the ceiling defined by at least 9 panels or over the entire ceiling, the area occupied by acoustic ceiling panels and illuminating according to the invention is at most 70% of the reference surface and preferably at least 20% of the reference surface and preferably from 30 to 50% of the reference surface.

In a particular embodiment in this reference region, two adjacent and disjoint panels (in particular at least one or both of them according to the invention as described above) have on their respective sides opposite each other (with each other). ) electrical contacts which are in electrical connection with a particularly metallic frame possibly electrically isolated and having an electroconductive zone oriented external face capable of electrically interconnecting said acoustic panels.

An acoustic ceiling according to the invention advantageously provides an illumination of at least 300lux and at most 900lux.

In one embodiment of the ceiling (in particular with the aforementioned frame masked), the first edge of a first acoustically preferably illuminating panel according to the invention is in contact with the second edge of a second acoustic panel possibly illuminating according to the invention. invention, in particular in contact with other acoustical panels possibly illuminating, the first and second songs being carrying electrical contacts forming electrical continuity by contact in particular for the transmission of control signals, power supply, data.

The layer of absorbent material may be a porous insulating material, preferably fibrous, based on mineral fibers of glass or rock, and / or organic fibers including cellulose or polymeric, and sometimes open porosity foam Advantageously, the acoustic absorbent material layer is based on mineral fibers.

The layer of acoustic absorbent material may preferably be monolayer or even formed of several superimposed layers or strata, these layers or layers may be of different compositions or natures.

According to the invention, the acoustic absorbent material layer may be a so-called "volume" layer with a thickness greater than or equal to 15 mm, preferably greater than or equal to 20 mm, more preferably greater than or equal to 40 mm, such as a panel compressed mineral fibers, in particular a fiberglass or compressed rock fiber board. Preferably, the acoustic absorbent material layer has a thickness greater than or equal to the thickness of the or each OLED module.

The so-called 'wet felt' acoustic ceiling panels are based on mineral fibers in general. They can be defined as composite panels based on fibers, generally mineral such as mineral wool, as well as cellulose fibers, a binder and various mineral constituents made from an aqueous suspension.

Each OLED module is for example received in a blind opening formed in the thickness of the layer between the inner face and the outer face. The OLED module can be flush with the inside face outside the notch.

A through hole in the thickness of the layer may be practiced for the power supply.

The technical edges of the OLED module are, for example, at most 1 mm. The panel is suspended from a building ceiling, with its inner surface facing the building interior and its outer surface facing the ceiling.

In one embodiment, the panel with OLED modules according to the invention is suspended from the ceiling in a localized manner, to the unit, for example above a workstation of a building occupant, while Other acoustic absorbent elements of the state of the art, without OLED module, are suspended from the rest of the ceiling. Alternatively, several acoustic panels according to the invention can be distributed regularly or randomly in a room, for example in an office.

It is also possible to vary the distance between each acoustic panel and the ceiling, so as to obtain a three-dimensional distribution of acoustic absorbers on the ceiling.

Another object of the invention is a ceiling assembly comprising a building ceiling and at least one acoustic absorbing panel as described above, the or each acoustic panel being suspended from the ceiling with its inner surface directed towards the interior of the building and its outer surface directed towards the ceiling. Ceiling means the lower side of a floor structure exposed in a room.

One can choose rigid or flexible OLED modules.

OLED modules that are disjoint and (just) in contact with the corners and preferably in the center of the panel (lambertian source preferably emitting in the white) can be chosen, for example rectangular (square), preferably less than 20 cm by less than 20cm.

Each panel (including rectangular) may include OLED modules in one or two sizes for example 10cm by 10cm and 5cm by 5cm and even LEDs and even a control unit for example powered to the mains via the plenum (via a hole in the sign)

Two acoustic panels (at least one being illuminating) are for example edge to edge, each may comprise at least one electrical contact zone on a border of the inner face extending on the edge which is edge to edge with said other edge of the another panel with another electrical contact zone on the other edge extending on a border of the inner face of this other panel. There may be two, three, four zones of electrical contacts, in particular each panel is edge to edge at one, two, three or four panels.

In the ceiling, some acoustic lighting panels can be replaced by acoustic panels without lighting sources (at least without OLED modules) but keeping the electrical contacts. So a continuity Electrical to transmit any electrical signal (power supply data, control) is panel by panel.
