(37) The views according to FIG. 7 shows an embodiment for fastening the switchgear cabinet luminaire 30 to a top-hat rail 17, as already explained above.

(38) The illustrations according to FIG. 8 show a fastening possibility via a base which is capable of being latched into recesses of profile strips.

(39) FIG. 9 relates to a fastening of the switchgear cabinet luminaire 30 via a screw base 23.

(40) The illustrations according to FIG. 10 relate to different possibilities for daisy-chaining several switchgear cabinet luminaires 30 via a rigid connection element 40. An outlet socket module 41 is further provided and there is the possibility to form a daisy-chaining of outlet socket module 41, battery module 42 and the actual switchgear cabinet luminaire 30.

(41) A special outlet socket module 41 can also be coupled for end-side termination. The cross-section of the switchgear cabinet luminaire is preferably formed in such a way that the luminaire can also be fixed with known, arc-shaped holding clamps, so that the universal usefulness and usability is further improved.

(42) It will be explained by reference to FIGS. 11a to 11d how several switchgear cabinet luminaires can be coupled via a connection element.

(43) As is shown in FIG. 11a, it is intended to connect two switchgear cabinet luminaires to the housing main body 1 and the translucent cover 32 as well as the electrical connection elements W and Z, and a hollow body 40 which is open on both sides is inserted as a connection element and the oppositely open sides of the hollow body have a cross-sectional area which is substantially complementary to the cross-sectional shape of the luminaire housing, such that the respective ends of the luminaire housing can be inserted into the hollow body 40 and locked there.

(44) Electrical connectors in form of pins X are arranged in or inserted into the interior of the hollow body 40.

(45) The switchgear cabinet luminaire is live (symbolised by the lightning sign) on the right side in the image in the example according to FIGS. 11a to 11d.

(46) As long as the left switch gear cabinet luminaire shown in FIGS. 11a to 11d has not yet been inserted into the respective open side of the hollow body 40, the pawl Y is in the blocking position with its blocking web Y2.

(47) This is shown in FIG. 11b.

(48) Only when the left switchgear cabinet luminaire was inserted into the open side of the hollow body 40, the face end of the respective luminaire housing comes into contact with the stop Y1 of the pawl Y. As a result, the blocking web Y2 moves downwardly according to the illustration in FIG. 11c, i.e. a movement of the blocking web Y2 occurs to its release position. According to the next following illustration 11d, the respective end of the luminaire housing of the switchgear cabinet luminaire shown on the right-hand side in the image can be pushed into the hollow body 40. The electrical connection between the two switchgear cabinet luminaires is now produced via the pins X.

(49) FIGS. 12a and 12b show how the separation of the two switchgear cabinet luminaires can be realised.

(50) In this respect, the action of a pressure force F on the detent lug G occurs according to the illustrated arrow in FIG. 12a in such a way that it is capable of moving out of a latching recess in the hollow body 40. As is shown in FIG. 12b, the right switchgear cabinet luminaire can then be removed from the connection element.
