Lighting device

1. A lighting device comprising:

a profiled element adapted to be applied to an external structure and made from an elastically deformable material;

a transparent or translucent longitudinal portion coupled to said profiled element and configured to allow passage of a luminous flux generated by a LED strip operating as an illuminating element, housed within a longitudinal chamber defined inside said profiled element, said wall having a longitudinal opening; and

a reflecting element housed in said profiled element in facing relationship to said illuminating element and oriented to reflect the luminous flux generated by said illuminating element towards said transparent or translucent portion coupled to said profiled element,

wherein said longitudinal chamber, which houses the illuminating element, is separate from a second longitudinal chamber which is defined inside said profiled element and which houses said reflecting element, and

wherein said LED strip is applied onto a support having thermo-dissipating properties, said support being engaged to an inner side of said wall so as to close said longitudinal opening and being directly coupled to means for constraining said profiled element to said external structure.

2. The lighting device according to claim 1 , wherein:

said transparent or translucent portion comprises a longitudinal band, which is formed in said profiled element or is associated to said profiled element, and is adjacent to said wall, and

said reflecting element comprises a strip of reflecting material which is facing and inclined with respect to said LED strip.

3. The lighting device according to claim 1 , wherein said transparent or translucent portion consists of:

a flat wall, bounded by two parallel faces,

a curved wall delimited by two parallel faces,

a biconvex or biconcave wall, or

a flat-convex wall or a flat-concave wall.

4. The lighting device according to claim 1 , wherein said longitudinal chamber of said profiled element which houses the illuminating element is filled with a sealing material resistant to water and humidity.

5. The lighting device according to claim 1 , wherein:

said longitudinal chamber, which houses said illuminating element, is shaped as a tubular cavity obtained in said profiled element and has a corresponding longitudinal opening for insertion of said illuminating element within said longitudinal chamber, and

said second longitudinal chamber, which houses said reflecting element, is shaped as a separate tubular cavity obtained in said profiled element and has a second corresponding longitudinal opening for insertion of said reflecting element within said second longitudinal chamber.

6. The lighting device according to claim 1 , wherein said reflecting element comprises a strip of reflecting material that is curved around a longitudinal axis.

7. The lighting device according to claim 1 , wherein said longitudinal chamber housing the illuminating element comprises a wall, in which:

at an inner surface of said wall, said illuminating element is applied, and

at an outer surface of said wall, there are associated means for constraining the profiled element to the external structure.

8. The lighting device according to claim 1 , wherein said transparent or translucent portion is made of:

a same material as said profiled element, or

a different material with respect to said profiled element and is subsequently applied to said profiled element.

9. The lighting device according to claim 1 , wherein said longitudinal chamber, which houses the illuminating element, is separated from the second longitudinal chamber, which houses the reflecting element, by a partition wall.

10. The lighting device according to claim 1 , wherein said profiled element is made of a silicone material.

11. The lighting device according to claim 1 , wherein said second longitudinal chamber is configured to hold and lock the reflecting element therein.

12. The lighting device according to claim 2 , wherein the wall of said longitudinal chamber, to which said illuminating element is applied, and the transparent or translucent portion are arranged perpendicularly to each other and said reflecting element is arranged at 45° with respect to the wall and the transparent or translucent longitudinal portion.

13. The lighting device according to claim 9 , wherein said partition wall is made of a transparent or translucent material adapted to allow the passage towards said reflecting element of the luminous flux generated by said illuminating element.

14. The lighting device according to claim 9 , wherein said partition wall is made of:

a same material as said profiled element, or

a different material with respect to said profiled element and is applied after said profiled element is manufactured.
