1. Luminaire - an appliance that distributes, transmits or alters light from one or more light sources and includes all parts 

necessary to support, secure and protect the light source

Components and the necessary circuit AIDS and devices to connect them to the power supply, but not the light source itself.

2. Class 0 luminaires - luminaires that rely on basic insulation for protection against electric shock.This means that the accessible 

conductive parts of the luminaire, if any, are not connected

Protective conductors in the fixed wiring of the facility, in case of failure of basic insulation, have to rely on the environment.

3. Class I luminaires - the protection against electric shock of luminaires not only relies on basic insulation, but also includes 

additional safety measures, i.e., accessible conductive parts connected to the device

Apply protection (grounding) to the conductor in the fixed wiring so that accessible conductive parts are not electrified in case of 

failure of basic insulation.

4. Class II luminaires - the protection of luminaires against electric shock not only depends on basic insulation, but also has additional 

safety measures, such as double insulation or reinforced insulation, without

Measures to protect the ground or to rely on installation conditions.

5. Class III lamps - anti-shock protection depends on the extremely low safety voltage (SELV) of the power supply, and it will not generate

 lamps with a voltage higher than SELV.

6. Rated voltage - the supply voltage of the luminaire specified by the manufacturer (the voltage of the luminaire in normal operation).

7. Power supply current - the current of the lamp supply terminal (Iin) under rated voltage, rated power and normal stable operation.
