摘要：
The invention relates to a luminous device (5) and a method for managing said device (5), comprising LED lighting means (51), a dissipative electric load (52) adapted to increase an electric power dissipated by the device (5) when the LED lighting means (51) are emitting light, and current interrupting means (53) configured for dynamically interrupting the flow of current through said dissipative load (52) when the LED lighting means (51) are emitting light, so as to reduce the electric power dissipated by said device (5).
