A device for illuminating an existing sign (100) having a specific given pattern on its front side, and a method of manufacturing such a device. A removable laminate (102) is intended to be applied to the front side of the sign, and comprises a mainly transparent cast compound or matrix (200) and a number of light emitting diodes (104) embedded in the matrix together with associated connected diode wires. The light emitting diodes are positioned in a specific pattern adapted to the existing pattern of the sign. Furthermore, a control unit (110) is configured to provide the light emitting diodes with electric current from a source of power supply (112) connected to the control unit, and to control the current feeding to the light emitting diodes in accordance with a predetermined scheme.

L'invention concerne un dispositif permettant d'éclairer un panneau existant (100), présentant un motif spécifique donné sur sa face avant, et un procédé de fabrication d'un tel dispositif. Un laminé amovible (102) est appliqué sur la face avant du panneau, lequel laminé comprend un composé ou une matrice coulée principalement transparente (200), et un certain nombre de diodes électroluminescentes (104) intégrées dans la matrice ainsi que des fils de diodes connectés associés. Ces diodes électroluminescentes sont positionnées dans une configuration spécifique conçue pour s'adapter au motif existant du panneau. En outre, l'invention concerne une unité de commande (110) configurée pour fournir du courant électrique aux diodes électroluminescentes, à partir d'une source d'alimentation (112) connectée à l'unité de commande, et pour commander le courant alimentant les diodes électroluminescentes, selon un programme prédéterminé.
