Definitions
- the present invention relates to a lighting device, and more particularly to a lighting device with light-emitting diodes, of substantially longitudinal shape, of the type intended to be suspended on a support for illuminating a subjacent area.
- lighting devices of substantially longitudinal shape, of the type intended to be suspended to illuminate a subjacent area, for example of the fluorescent tube type, suspended on a support, generally the ceiling of a room, in order to to illuminate a subjacent area.
- the present invention aims to overcome all or part of these disadvantages by providing a lighting device with a possibility of orderly storage of the electric cables and in fact having a smaller footprint.
- the subject of the present invention is a device for illuminating a subjacent zone, characterized in that it comprises:
- a printed circuit comprising an upper face, intended to be oriented in the direction of the support, a lower face supporting and electrically interconnecting a plurality of light-emitting diodes, a first end attached to a first end housing intended to receive light-emitting means; supplying the electroluminescent diodes, and a second end attached to a second end housing, and means for supporting and passing at least one electrical cable, attached to the first end housing and to the second end housing and intended to guide each electrical cable along the printed circuit between the first end housing and the second end box, the support means and passage of each electrical cable extending along the printed circuit.
- the lighting device according to the invention offers a smaller footprint, thanks to the support means and passage of each electrical cable that allow ordered storage of each electric cable along the printed circuit.
- Light-emitting diodes provide a long service life and significantly reduced power consumption.
- each electrical cable comprise at least one profile, each profile comprising a first end connected to the first end housing, a second end connected to the second end. end housing, and a cavity opening at the first end and the second end and for receiving each electrical cable.
- the first end housing and the second end housing are shaped to receive respectively the first end and the second end of each profile, and the first housing of end and the second end housing comprise at least one opening arranged opposite the cavity of each profile.
- the printed circuit comprises two lateral edges each extending from the first end to the second end of the printed circuit and each section is shaped to conform to the contour of one of the lateral edges.
- each electrical cable advantageously passes on both sides of the printed circuit. This makes it possible to avoid having it (s) loose in bulk above the upper face. This results in less space, but also in a lack of obstruction of the space between the upper face and the support.
- each profile comprises two ribs delimiting between them a space for receiving the side edge of the printed circuit.
- each section is metal, for example aluminum.
- This characteristic has the advantage of providing good thermal conduction between the printed circuit and each profile. Each profile thus contributes to the heat dissipation of the heat generated by the lighting device in operation.
- the upper face of the printed circuit is in direct contact with the ambient air.
- the heat dissipation of the heat generated by the lighting device in operation is ensured directly by the contact of the upper face of the printed circuit with the ambient air. This also eliminates the use of a heat sink connected to the upper face of the printed circuit, thus limiting the size.
- the first end housing and the second end housing each comprise a protruding portion projecting beyond a plane comprising the upper face of the plate, each protruding portion being intended to be fixed to the support via the fastening means and suspension.
- the upper face of the plate is disposed at a distance from the support when the device is fixed and suspended from the support. Maintaining a predetermined distance between the upper face of the printed circuit and the support makes it possible to ensure direct contact between the upper face and the ambient air. This ensures between the upper face and the support the existence of a volume of air suitable for effective heat dissipation. The greater the space left between the upper face of the plate and the support, the greater the amount of air likely to dissipate the heat generated by the lighting device in operation, and the more this air will have the possibility of to be renewed by convection.
- the means for fixing and suspending a support comprise at least one fastener substantially in the shape of an inverted U, each fastener comprising a base intended to be fixed to the support by fixing means and two lugs intended to to be attached to the first end housing or the second end housing, each tab including at least one rim shaped to be inserted into a space defined by two notches formed on the first end housing or the second end housing.
- the lighting device according to the invention can be unhooked from the support by an operator in several times. This proves to be particularly advantageous for lighting devices of large dimensions (of great length in particular). Indeed, the operator can initially act on the means for attaching the tabs to the first or second end housing. The first or second end housing (thus the lighting device) is then retained only by the cooperation of the rim and notches, the flange being engaged in the space defined by the notches. This gives the operator time to clear the other end box in the same way. When the device is retained only by the engagement of the edges of the tabs between the notches of the end housings, it is sufficient for the user to draw the lighting device to him so as to overcome the resistance due to the engagement of the edges in the space delimited by the respective detents.
- the second end housing is intended to receive means for receiving a wireless signal and control means of the power supply means for controlling the ignition or the extinction of the light-emitting diodes according to the information received by the wireless signal receiving means.
- the illumination and extinction of the light-emitting diodes of the device according to the invention can be controlled remotely, for example by detecting the presence of a person at the entrance or exit of the room in which the the lighting devices according to the invention.
- the second end housing comprises means for passing at least one electrical cable for connection to the first end housing of a separate lighting device.
- the lighting device according to the invention can be connected to another lighting device having the aforementioned characteristics so as to form a set of lighting devices according to the invention for illuminating a room together.
- FIG. 1 is a side view of a lighting device according to one embodiment of the invention.
- FIG. 2 is a perspective and top view of a lighting device according to one embodiment of the invention.
- FIG. 3 is a perspective view from below of a lighting device according to one embodiment of the invention.
