Several countries in Europe are using a special type of plugs for connection of lamps. In particular connection of hanging lamps is more safe with special sockets and plugs than using free wires and simple plastic terminal connectors. Lamp plugs are significant smaller than standard domestic plugs.

France: devices for connection of luminaires (DCL) are shown below (images 1 - 10).
Sweden: a different type of lamp plugs are shown further down (images 11-18).
Denmark: a third type of lamp plugs are shown in the Danish standard gallery (click here).

 

France,  Dispositifs de Connextion Luminaires (DCL), also used in Norway.

DCL sockets and plugs comply with IEC 61955 standard. The use of these devices in new and renovated homes in France became mandatory in 2001
(Norme Française NF C 15-100). Identical DCL lamp sockets and plugs are available in Norway and will be compulsory in 2019. Other EU countries may follow.

1, 5
DCL type lamp socket for ceiling mounting. Rated at 6A - 250V. Image no. 5 shows the same socket with hook and plug (image nos 2 - 4 show plug in detail). When mounting material that is provided with a ceiling conduit box (not shown) is properly used lamps with a weight up to 25 kg can be used. Pin contacts are deeply recessed (24.5 mm). All lamp sockets have a lamp symbol (see no. 5, bottom left).
Each of the devices shown in image nos. 1 - 10 are made by Legrand, France.
2 - 4
DCL type lamp plug, rated at 6A - 250V. Dimensions: width = 30.2 mm and height = 24.2 mm + length of pins. Pins have a length of 7 mm (L and N) or 8 mm (earth) and are 2.8 mm wide and 0.8 mm thick. Plug fixation in the recessed outlet is ensured by a clip.
To fix wires to a plug two small side clips have to be lifted simultaneously, a quite difficult procedure. Plugs made by other manufacturers, for example Elko in Norway, use a screw to fit together the two plug parts; see image no. 12.

9 DCL type socket for wall mounting. Because it has no hook the recessed plug contacts have a central position. Other specifications are identical to models for ceiling mounting (see nos. 1 and 5).
10 DCL type lamp sockets are primarily meant for first use in new, yet unfurnished rooms. It is likely that finally the lamp socket will be replaced by a more attractive type of illumination. Therefore lamp holders come with a separate plug.

The visible side of the socket is essentially comparable to image no. 5.

12 DCL plug made by Elko. The upper and lower half of the housing are joined by a screw. Compare with the Legrand plug no. 4.
