Damp room luminaires - luminaires for damp roomsAs with sockets, the same applies to lights in damp areas: electricity and humidity are not very well-tolerated. Therefore special lights must be used in damp rooms.
Which requirements lamps and illuminants have to meet in the various areas of wet rooms is specified in DIN VDE 0100 Part 701. There is a distinction between three protection areas. This DIN also states that switches and sockets are generally not allowed in the protected areas. An exception are switches that are installed in damp-proof lights and do not reduce the degree of protection. Then they may be used in the protection areas 1 and 2.
Protection range 0
The protection area 0 covers the interior of bathtubs or shower trays. Lamps and luminaires may only be operated with safety extra-low voltage, ie up to a maximum of 12 volts. In addition, the luminaires used must be expressly approved for installations in this area. The degree of protection IP X7 must at least be met.
Protection zone 1
The protection area 1 extends in a diameter of 120 centimeters around a fixed water outlet point or around the shower head of
Shower in rest position. Luminaires used in this area may also only be operated with a safety extra-low voltage of a maximum of 12 volts. It should be noted that the voltage transformers, which reduce the mains voltage to the necessary safety extra-low voltage, must be installed outside the protection zones 0 and 1.
Protection zone 2
Within a radius of 60 centimeters around the protection area 1, the protection area 2 adjoins. As in protection zone 1, lamps and illuminants that are protected against splash water, ie at least IP x4 protection, must be used here. If the luminaires are located in an area where they can come into contact with water jets, for example through water jets in whirlpools, they must have protection class IP X5, ie be protected against water jets.
Power lines to the lights
If jetty lines are used to connect wet room luminaires, they may only be laid under plaster. A depth of at least six centimeters must be observed. On the other hand, sheathed cables may be laid under or on the plaster. They are therefore suitable for basements and garages.
