Abstract
A lighting unit with discharge lamps, particularly for spotlights and the like, comprising a discharge lamp inside a containment enclosure and ventilation elements for cooling the lamp, a control unit that drives a lamp power supply to supply variable power levels to the lamp and a fan power supply for actuating the ventilation elements at a variable speed. The control unit is controlled by signals imparted from outside and/or by signals that can be derived from measurements taken inside the lighting unit.

A lighting unit with discharge lamps for spotlights, comprising:
- a containment enclosure;
- at least one discharge lamp located inside said containment enclosure;
- at least one ventilation element for cooling said at least one discharge lamp;
- a fan power supply;
- a control unit that drives said fan power supply in order to actuate said at least one ventilation element at a variable speed and measurement signals derived from measurements of operating conditions inside and outside the lighting unit, said control unit being controlled by said measurement signals.
A lighting unit with discharge lamps for spotlights, comprising:
- a containment enclosure;
- at least one discharge lamp located inside said containment enclosure;
- at least one filter that is insertable in an emitted light beam;
- a lamp power supply;
- a control unit that drives said lamp power supply for supplying said at least one lamp with variable power levels;
- and a motor for actuating said at least one color filter, said control unit being controlled by said motor.
A lighting unit with discharge lamps for spotlights, comprising:
- a containment enclosure;
- at least one discharge lamp located inside said containment enclosure;
- at least one color temperature correction filter;
- a lamp power supply;
- a motor for actuating said color temperature correction filter;
- and a control unit that drives said lamp power supply for supplying variable power levels to said at least one lamp, said control unit being connected with said motor for receiving signals indicating operating conditions therefrom.
