What is a luminous ceiling?
Protection class I
The first class stands for protective earthing, whereby all metallic and conductive housing parts of the luminaire are connected to the so-called protective conductor system of the fixed electrical installation. In the event of a faulty voltage, a fuse is activated which de-energizes the circuit so that you do not receive a shock.
This lamp protection class is very often found in ceiling lights that are connected to the protective conductor system via the power outlet in the ceiling.
Protection class II
In lamp class 2, there is reinforced or double insulation between the mains circuit and the conductive housing of the lighting, which is usually called protective insulation. This means that a luminaire with protection class 2 is protected even if it is made of a conductive material.
A lamp with protective insulation therefore no longer needs to be connected to an additional protective conductor connection as in protection class 1. This usually applies to Standing or table lamps, which simply need to be plugged into the socket and they are ready for use. These lamps often have a typical Euro plug - an example of a class 2 plug.
Protection class III
In lamp class 3 there is a so-called safety extra-low voltage, whereby the lamps marked with this symbol are operated with a maximum voltage of 50 volts AC or 120 volts DC. As in protection class 2, they also have double insulation between the mains circuit and the output voltage.
In addition, some of these lamps in protection class 3 require a safety transformer in accordance with DIN EN 61558-2-6, which can only be dispensed with in the case of safety extra-low voltages from rechargeable batteries or batteries. A protective conductor connection is not permitted here.
Where can I find the protection class of lamps?
To find out the protection class of lamps, all you need to do in the skapetze® online store, just take a look at the product properties. There you will usually find the class under the technical data. If you are unable to find it, please contact our customer service team.
We will always help you. If you are visiting us on site in Simbach am Inn, simply ask us directly for the protection class. Otherwise, this can also be found on the packaging and sometimes directly on the base of the lamp itself.
Which protection class for which rooms?
You cannot decide which rooms a light is ultimately suitable for based solely on the lamp protection class. For example, whether a lamp is suitable for protection class 2 bathrooms or not depends primarily on the protection class, because this area is mainly about protection against water.
The same applies to the use of a luminaire outdoors, where foreign bodies such as dirt also play an increasingly important role.
