Abstract

A lighting method comprising: definition, by a control system (CTRL_S) of a lighting device (HL), of a parameter (PAR) of the lighting device; transmission of this parameter, by the control system, to an actuator (LSS) of the lighting device; and generation, by the actuator, with a light source (LSR) of the lighting device, of a light beam producing an image corresponding to a light map obtained by modifying a light map stored in the actuator using the parameter received from the control system. The description also relates to a lighting device, a computer program and a storage medium for implementing such a method.
