Description

The present invention relates to a lighting device comprising a flexible ribbon incorporating light-emitting diodes.

This invention relates to the field of manufacturing lighting devices, especially those intended to be installed temporarily. These lighting devices find particular application in the field of events, entertainment and audiovisual.

In these areas, it is necessary that these lighting devices can be quickly installed, moved, disassembled and / or that the lighting they produce can quickly be changed.

In particular, in the field of theater or cinema in the studio, the lighting is likely to change from one stage to another or from one stage to another so that these lighting devices must at least be able to be moved quickly and / or the lighting produced can be quickly changed.

It should also be noted that, in the audiovisual sector, filming is taking place less and less in the studio but more and more in natural scenery. In this context, the lighting devices used must then be able to be quickly moved but also quickly mounted, installed and dismantled. In this context too, it is necessary that the lighting produced by these devices can quickly be modified.

In fact, when it is a question of modifying the lighting produced by a lighting device, it is customary to resort to a system, independent of the lighting device, and constituted by a panel diffusing or reflecting the light. Such a panel is held at arm's length by an operator which proves to be a painful and tedious operation for this operator. Such a panel can also be fixed on a foot which, when changing the lighting, requires disassembly of the panel (especially for the purpose of replacement) which is a long and tedious operation. In addition, a set, constituted by such a foot and by such a panel, is heavy and bulky so that its movement and manipulation are painful operations.
