Lighting and/or signaling device with scrolling effect

Light-emitting device, especially for lighting and/or signaling, especially for a motor vehicle, comprising:

• at least a first electroluminescent module and a second electroluminescent module energized in series;
• each electroluminescent module comprising, in parallel:
• a first branch comprising a light source having a first direct threshold voltage beyond which the light source is gated on;
• a second branch comprising an element such that the voltage on the terminals of said element is less than the first direct threshold voltage of the light source;
• a third branch comprising a timing module able to time a predetermined period and modify, at the end of said predetermined period, an overall impedance of the second branch so that a voltage in the second branch is greater than or equal to said first direct threshold voltage of the light source;
• wherein the predetermined period in the first electroluminescent module is less than the predetermined period in the second electroluminescent module.
