Display of light patterns on a flexible guide sheet

A method for controlling a luminous module, the luminous module includes an assembly of at least one flexible guide sheet, with each flexible guide sheet of the assembly being able to receive luminous rays via at least one edge of the flexible guide sheet and to reflect the luminous rays in a direction substantially normal to a surface of the flexible guide sheet according to at least one pattern etched in the flexible guide sheet, wherein the assembly is able to reflect light according to a first pattern and a second pattern etched in the assembly, at least one first and one second light injection element, with each of the first and second injection elements being able to receive light and to distribute the light throughout the assembly of at least one flexible guide sheet, at least one light source able to selectively inject light into the first light injection element and into the second light injection element, wherein the first light injection element and the assembly of at least one flexible guide sheet are arranged in such a way as to project light according to the first pattern and wherein the second light injection element and the assembly of at least one flexible guide sheet are arranged in such a way as to project light according to the second pattern, implemented by a control element able to control the at least one light source in order to selectively project light according to the first pattern and according to the second pattern, the method comprising receiving an animation command, with the animation command identifying an animation including a series of patterns including the first pattern and the second pattern, and controlling the at least one light source as a function of the animation command, in such a way as to dynamically project the animation.

A method for manufacturing a luminous module comprising the following steps of:

• providing a roll of flexible film able to guide light in the thickness thereof;
• etching at least one first and one second pattern on the roll of flexible film using ultra-violet printing;
• cutting the roll in order to obtain an assembly of at least one flexible guide sheet with a given dimension, with the assembly comprising the first pattern and the second pattern;
• arranging a first injection element and a second injection element relative to the assembly of at least one flexible guide sheet in order to form a luminous module;
• arranging at least one light source in the luminous module in such a way as to selectively inject light into the first light injection element and into the second light injection element;
• wherein the first light injection element and the assembly of at least one flexible guide sheet are arranged so as to project light according to the first pattern and wherein the second light injection element and the assembly of at least one flexible guide sheet are arranged in such a way as to project light according to the second pattern.
