Lighting and/or signaling light-emitting device for vehicles
First Claim
1. A light-emitting device for a motor vehicle, including:
- at least one first light source to emit a first modulated light beam coding information;
at least one second light source to emit a second modulated light beam coding information;
a control device adapted;
to determine, on receiving information to be transmitted via said light-emitting device, if said first modulated light beam emitted by said at least one first light source should be modulated to code said information to be transmitted or if said second modulated light beam emitted by said at least one second light source should be modulated to code said information to be transmitted, said determination depending on information relating to a local solar illumination;
as a function of said determination, to modulated said first modulated light beam and/or the energization of said second modulated light beam to code said information to be transmitted;
wherein a controller is configured to modify a first energization signal at a first coding frequency less than a second coding frequency used to effect the modification of a second energization signal.

Abstract
A light-emitting device, notably a lighting and/or signaling device for a motor vehicle, including at least one first light source intended to emit a first modulated light beam coding information; at least one second light source intended to emit a second modulated light beam coding information; a control device adapted: to determine, on receiving information to be transmitted via the light-emitting device, if a first light beam intended to be emitted by the first source should be modulated to code the information to be transmitted and/or if a second beam intended to be emitted by the second source should be modulated to code the information to be transmitted, the determination depending on information relating to the local solar illumination; as a function of the determination, to modulate the first light beam and/or the energization second light beam to code the information to be transmitted.

12. A light-emitting device for a motor vehicle, including:
-
a light source; a controller adapted; to modify an energization signal of said light source to code information to be transmitted, the modification of said energization signal including multiplication of said energization signal with a coding signal including forms repeated in said energization signal, said forms having a given temporal extension and an amplitude, on reception of a command, to reduce said temporal extension of said forms and to increase said amplitude of said forms in said energization signal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
