Abstract

A lighting device may include a strip-like carrier with a first and a second opposed faces with light radiation sources on the first face, and a strip-like profiled member having a pi-shaped cross section, including a channel-like central portion with a bottom wall and side walls. The strip-like carrier is arranged in the profiled member with the first face and the light radiation sources facing outwardly of the central portion and the second face facing the bottom wall of central portion. The pi-shaped profiled member includes two sidewise extensions laterally to the central portion, to provide lateral fixing formations for the lighting device.

First claim

The invention claimed is:

1. A method of mounting a lighting device on a mounting surface, the method comprising:
providing a lighting device comprising:
a strip-like carrier member with first and second opposed faces with light radiation sources provided on said first face,
a strip-like profiled member having a pi-shaped cross section including a channel-like central portion with a bottom wall and lateral side walls,
wherein:
said strip-like carrier member is arranged in said pi-shaped profiled member with said first face and said light radiation sources facing outwardly of said central portion and said second face facing the bottom wall of said channel-like central portion,
said pi-shaped profiled member includes two extensions sidewise of said central portion to provide lateral fixing formations for the lighting device, both of said carrier member and said pi-shaped profiled member are flexible, and

a potting mass above said strip-like carrier member sealing the channel-like profile of said central portion of the strip-like profiled member by enclosing said strip-like carrier member,
the method comprising:
providing a mounting housing,
wherein the mounting housing has a strip-like body having a longitudinal cavity;
wherein the longitudinal cavity extends throughout the length of the mounting housing,

applying said mounting housing on said mounting surface,
coupling the lighting device to said mounting housing by causing said sidewise extensions of the pi-shaped profiled member of the lighting device to extend in opposed grooves of said mounting housing.

2. The method of claim 1 , further comprising coupling said lighting device to said mounting housing by a relative longitudinal movement of said lighting device and said mounting housing.

3. The method of claim 1 , wherein said applying said mounting housing on said mounting surface precedes said coupling said lighting device with said mounting housing.

4. A lighting device, comprising:
a strip-like carrier member with first and second opposed faces with light radiation sources provided on said first face,
a strip-like profiled member having a pi-shaped cross section including a channel-like central portion with a bottom wall and lateral side walls,
wherein:
said strip-like carrier member is arranged in said pi-shaped profiled member with said first face and said light radiation sources facing outwardly of said central portion and said second face facing the bottom wall of said channel-like central portion,
said pi-shaped profiled member includes two extensions sidewise of said central portion to provide lateral fixing formations for the lighting device, both of said carrier member and said pi-shaped profiled member are flexible, and

a potting mass above said strip-like carrier member sealing the channel-like profile of said central portion of the strip-like profiled member by enclosing said strip-like carrier member
a lighting device mounting housing having a strip-like body having a longitudinal cavity therein, wherein:
said longitudinal cavity extends throughout the length of the lighting device mounting housing,
said longitudinal cavity includes two parallel side surfaces and a bottom surface with opposed grooves extending sidewise of said bottom surface longitudinally of the strip-like body, and
said grooves are adapted to receive said sidewise extensions of the pi-shaped profiled member of the said lighting device.

5. The lighting device of claim 4 , wherein said sidewise extension extends over the whole length of said pi-shaped profiled member.

6. The lighting device of claim 4 , wherein said pi-shaped profiled member includes a silicone material.

7. The lighting device of claim 4 , wherein said potting mass includes a transparent silicone material.

8. The lighting device of claim 4 , wherein said lateral side walls are parallel to each other and extend perpendicularly from the bottom wall of the central portion.

9. The lighting device of claim 1 , wherein said lateral side walls are parallel to each other and extend perpendicularly from the bottom wall of the central portion.
