FR3085067A1 - LIGHTING DEVICE FOR A CEILING SUSPENDED ON THE OBJECT OF RECONSTRUCTING IN A ROOM LIGHTING WHICH CAN CHANGE AT ANY TIME IN COLOR, INTENSITY OR POSITION OF LUMINAIRES - Google Patents

Description

Lighting device for ceilings suspended from the object of reconstituting in a room lighting that can change at any time: color and intensity or position of the lights on the ceiling without altering the aesthetic state of the latter

DESCRIPTION

The invention relates to a lighting device for suspended ceilings inside a room with the object of reconstituting lighting which can change at any time color, intensity or position on the ceiling at interior of the room, according to the principle of removable LED lights leaving no trace on the ceiling and finding their connections at any point on the ceiling having received the device, while inside the same room several fields of colors and d intensity are distributed.

Knowing state:

The state of knowledge in the field of suspended ceiling devices is characterized by several technologies:

The most common is that of light boxes which replace plates placed on the suspended ceiling rails. This technology requires for each box a dedicated power supply which is designed for the use of the box on this specific location, so that it is not possible to change the location of the electrical installation without taking over the network. power supply. In addition, this type of device produces circumscribed light and does not make it possible to obtain uniformity of lighting over the lighting area.

- Another technology consists in bringing together rows of rails suspended from the object of placing a luminaire between these close rails (see manufacturer "Armstrong"). This technology suffers from the same constraints as that preceding, and adds a problem in that the displacement of the luminaires is here impossible because the rails do not have a regular spacing positioning.

- Yet another technology consists in integrating the luminaire inside the rails (cf. WO 2017119858). This principle of technology makes it possible to acquire homogeneity of lighting, but is constrained in that no displacement of lighting is possible after the fact that the supply is governed by the initial implantation of the device. In addition, this device is constrained in that it does not allow lighting in the corners of the room.

In terms of connection to the electrical network, the state of knowledge is characterized either by conventional domestic dedicated power supplies, or by low-voltage devices with a transformer module making it possible to obtain low voltage from the domestic network. These technologies do not allow any retrofitting of the lights without damaging the ceiling. Just as these fixtures must always be brought back to a power source, so that this must be thought of when designing the room.

Presentation of the device:

The invention relates to a lighting device for suspended ceilings inside a room with the object of reconstructing lighting that can change color, intensity or position on the ceiling at any time. interior of the room according to the principle of removable LED luminaires leaving no trace on the ceiling and finding their connections at any point on the ceiling having received the device, while inside the same room several fields of colors and intensity are distributed.

The device (Figure 1) is characterized in its components by:

- A 12-volt voltage transformer (a) connected to the domestic network at the rate of at least one transformer per room receiving the device,

- Which supplies a controller (b), the latter receives two wired connections (c) - one positive and the other negative in the introductory phase, while it supplies a main RGB network (d) consisting of four or five wires (a positive, a green, a red, a blue and possibly a white),

- The main network of the room supplied with RGB (Red-Green-Blue) (d) takes the form of a mesh which covers the entire surface of the room, main RGB network (d) positioned more precisely in its height between the rails of the suspended ceiling and the ceiling so as not to be visible once the suspended ceiling has its facing plates. The requirement here is that this network covers the entire surface of the room in such a way as to supply a luminaire that can be placed below it at all times,

Luminaires maintained on the conventional rails constituting the supporting structure of the suspended ceiling (e), according to a principle of clips (f) being produced on the flat part of the rail (g) while this system of clips (f) is fixed on the luminaire (h) and holding in its position under the rail (e) on the visible side of the suspended ceiling,

An RGB link between the luminaire and the main RGB network (d) placed between the ceiling and the suspended ceiling structure, consisting of:

o A link network (i) between the luminaire (h) and the main RGB network (d) composed either of as many wires as that of the main network (d) (Figure 2), or even as many contacts as than that of the main network (d) (figure 3), o A connection Q) between the luminaire (h) and the connection network (i) (figures 2 and 3) which passes through the interior of the clips ( f) (figure 2) (embedded in it) in order to be concealed in contact with the rail (g) and not to disturb the aesthetic homogeneity of the visible part of the suspended ceiling, o Of a connection (k) between the main RGB network (d) and the link network (i) made up of a pin system (I) on the one hand ensuring the connection to the positive wire (I '), while it will have another pin to connect to the other colored wire according to the one chosen (I) (green, red, blue and possibly a white). Ideally, this connection can take different forms using either dedicated connection pin systems, or other forms of adjustable pins.

Relative to the process of implementing the device once that installed in the structure (connection of the power supply system to the controller and to the main RGB network), the operating principle consists in determining the lighting zones according to the desired rendering, to prepare the connections of the luminaires according to the desired renderings (locations choice of colors and intensity), i.e. to adjust the pin system (I) of the connectors (k) to the main RGB network (d) , connect them and then clip the luminaires onto the rails at the established locations. Finally it will be a matter of positioning the ceiling facing plates.

If the luminaires have to change location, it will be a question of lifting the facing plate, unclipping the luminaire and removing the connection (k) to the main RGB network (d), then then replacing the facing.

In the event that the luminaires change their function (color or intensity), the connection (k) to the main RGB network (d) is modified so as to be in contact with the wire (I) of chosen color or intensity.
