Abstract

A luminaire ( 2 a, 2 b, 2 c, 2 d ) comprising a housing with a first end surface ( 21 ), a second end surface ( 22 ), an at least partially circumferential surface ( 23 ) extending between the first end surface and the second end surface, a longitudinal direction ( 25 ) extending between the first end surface and the second end surface, and at least one connection device ( 3 a, 3 b; 3 a ′, 3 b′; 3 a ″, 3 b ″) for connecting the luminaire to a complementary connection device ( 3 b, 3 a; 3 b ′, 3 a′; 3 b ″, 3 a ″) of another corresponding luminaire, the at least one connection device being arranged on either of the first end surface and the second end surface of the luminaire, the connection device comprising an electrical connection element ( 34 ) extending in an angleγ with respect to said longitudinal direction ( 25 ) of said luminaire, said angle being comprised in the interval (0°; 90°].

First claim

The invention claimed is:

1. A luminaire comprising:
a housing with a first end surface, a second end surface, an at least partially circumferential surface extending between said first end surface and said second end surface, a longitudinal direction extending between said first end surface and said second end surface, and
at least one connection device for connecting said luminaire to a complementary connection device of another corresponding luminaire, said at least one connection device being arranged on either of said first end surface and said second end surface of said luminaire,
said connection device comprising an electrical connection element extending in an angle γ with respect to said longitudinal direction of said luminaire, said angle being comprised in the interval (0°; 90°];
wherein said connection device further comprises a first surface, wherein said first surface extends in an angle β with respect to said longitudinal direction of said luminaire, said angle β being comprised in the interval 0°<β<90°;
wherein said connection device further comprises a second surface, said second surface being rounded, and wherein said first surface and said second surface meet in a tip point, the location of the tip point on the connection device satisfying the relation
y 2 ≧y 1*(1−sin β),

where y1 is the height of the luminaire and y2 is the shortest distance measured in a mounted condition of said luminaire between said tip point and a surface on which the luminaire is mounted.

2. A luminaire according to claim 1 , wherein said electrical connection element is integrated in the first surface.

3. A luminaire according to claim 1 , wherein said connection device further comprises an at least partially circumferential wall extending between said first surface and said second surface.

4. A luminaire according to claim 1 , wherein said connection device further comprises an engagement element adapted for engagement with a complementary engagement element of another connection device.

5. A luminaire according to claim 1 , comprising two connection devices at opposite end surfaces, wherein one connection device being of a male type and one connection device being of a female type.

6. A luminaire according to claim 1 , wherein the first surface is curved.

7. A method for mechanically and electrically connecting at least two luminaires with each other, comprising the steps of:
providing at least two luminaires according to claim 1 ,
mounting a first luminaire in a first fixed position on a surface, and
mechanically and electrically connecting a subsequent luminaire to said first luminaire, wherein the step of mechanically and electrically connecting said subsequent luminaire comprises the steps of:
guiding a connection device of said subsequent luminaire into a position above a complementary connection device of said first luminaire,
bringing said connection device of said subsequent luminaire into mechanical and electrical connection with said complementary connection device of said first luminaire by rotating said subsequent luminaire in such a way that said connection device of said subsequent luminaire is brought into physical and electrical contact with said complementary connection device of said first luminaire, and
mounting said subsequent luminaire in a second fixed position on said surface.

8. A method according to claim 7 , wherein said step of mounting a first luminaire in a first fixed position on a surface comprises:
providing at least one mounting bracket,
mounting a mounting bracket in said first fixed position on said surface, and
mechanically connecting said first luminaire to said mounting bracket.

9. A method according to claim 7 , wherein said step of mounting said subsequent luminaire in a second fixed position on said surface comprises:
providing at least one mounting bracket,
mounting a mounting bracket in said second fixed position on said surface, and
mechanically connecting said second luminaire to said mounting bracket.

10. A method for mechanically and electrically disconnecting at least two luminaires with each other, comprising the steps of:
providing at least two luminaires according to claim 1 , each being mounted in a fixed position on a surface,
bringing a connection device of a first luminaire out of mechanical and electrical connection with a complementary connection device of a subsequent luminaire by rotating said first luminaire in such a way that said connection device of said first luminaire is brought towards said surface in such a way that said connection device of said subsequent luminaire is brought out of physical and electrical contact with said complementary connection device of said first luminaire,
demounting said first luminaire from said fixed position on said surface in which it is mounted, and
removing said first luminaire from said surface and said subsequent luminaire.

11. A method according to claim 10 , wherein said first luminaire is mounted in said fixed position on said surface by means of mechanical connection with a mounting bracket, and wherein said step of demounting said first luminaire from said fixed position on said surface comprises mechanically disconnecting said first luminaire from said mounting bracket.
