DRIVERS AND OPERATING DEVICES TRANSFORM POWER INTO LIGHT
LED light sources require operating devices for energy supply or for the transformation of electricity into light. LED drivers or operating devices provide the appropriate power supply. The influence of the operating mode on the energy balance of the entire system must be considered. Due to the low efficiency losses, LED systems with constant current supply are especially recommended. Also common are constant voltage operated LEDs, which are usually operated with 12 V or 24 V. However, there is also a tendency to use systems with 48 V operating voltage. Voltages below 50 V are called safety extra-low voltage. The advantage of these designs is that no electrician is required for the connection.
