Abstract (en)
[origin: EP2477462A2] The system (1) has a voltage supply device (4) i.e. central battery system, connected with lights by a light supply line (3). The supply device supplies light groups (7) as a part of lights (2), and is switchable between a network voltage supply (5) and an emergency voltage supply (6). The supply device includes a dimming control e.g. phase controlled modulator, for the light groups. The dimming control is associated to the network voltage supply and the emergency voltage supply. The lights include a LED as an illuminant. The light supply line is designed for data communication. An independent claim is also included for a method for simultaneously dimming lights.
