Portable electric lighting fixture
First Claim
1. A portable electrical luminaire, comprising:
- a supporting body having an upper support end and a lower support end;
a lamp base disposed on said upper support end and configured to accommodate a luminous device;
a reflector surrounding said lamp base for indirect space illumination;
an electrical connection between said lamp base and a connection plug for connecting to a power supply system; and
an electronic control device connected and configured to automatically limit an electrical power drawn by said luminous device from the power supply system to a predetermined power value, said electronic control device including first means for detecting an actual current and second means configured to use a comparison of a power value, derived from the actual current and from an actual voltage, with a reference value to limit the actual current such that the electrical power drawn is less than or equal to a maximum power value.
