Means of lighting for device with power supply which supplies DC current has nominal voltage of lamp lying below nominal or operating voltage of power supply, whereby transformer is installed on for variable input voltages

摘要

The means of lighting for device (2) with a power supply which supplies DC current has the nominal voltage of the lamp (4) lying below the nominal or operating voltage of the power supply (3), whereby a transformer (5) is installed on the lighting means (1) for variable input voltages with a safety switch (6) to protect the lamp against an overload. The transformer is located in or on the housing (7) of the lighting means and controls the voltage supply of the lamp.
