Lighting strip and lighting device
A lighting strip comprises a flexible printed circuit strip. The flexible printed circuit strip comprises a plurality of wiring portions and a plurality of carrying portions. The plurality of wiring portions are configured to supply electrical power to the plurality of carrying portions. The lighting strip comprises a plurality of solid-state lighting elements respectively disposed on the plurality of carrying portions. The plurality of wiring portions include at least one pitch adjusting portion configured to adjust a pitch between two adjacent carrying portions and to enable the flexible printed circuit strip to be arranged in a three-dimensional shape.
1. A device comprising:
a plurality of wiring portions comprising at least one pitch adjusting portion between two adjacent wiring portions such that the at least one pitch adjusting portion comprises at least one flexible arm having an opening; and
a plurality of carrying portions such that at least one carrying portion protrudes from a respective wiring portion.
2. The device of claim 1 , wherein the at least one pitch adjusting portion adjusts a pitch between two adjacent carrying portions.
3. The device of claim 1 , wherein the opening is V-shaped.
4. The device of claim 1 , wherein the opening is U-shaped.
5. The device of claim 1 , wherein the at least one flexible arm opens in a direction identical with a direction in which a carrying portion protrudes from a respective wiring portion.
6. The device of claim 1 , wherein the at least one flexible arm opens in a direction opposite to a direction in which a carrying portion protrudes from a respective wiring portion.
7. The device of claim 1 , wherein the at least one flexible arm is bendable or foldable in at least a horizontal position and a vertical position.
8. The device of claim 1 further comprising at least one light emitting element on at least one carrying portion.
9. The device of claim 8 , wherein the at least one light emitting element is a light emitting diode (LED).
10. The device of claim 1 , wherein at least one of the plurality of wiring portions is connected to an electrical power supply.
11. The device of claim 1 , wherein the plurality of carrying portions protrude from a respective wiring portion in a rectangular tooth shaped pattern.
12. The device of claim 1 , wherein the plurality of wiring portions and the plurality of carrying portions are made of a same material.
13. The device of claim 1 , wherein the plurality of wiring portions and the plurality of carrying portions are made of a flexible polymer.
14. The device of claim 1 , wherein the plurality of wiring portions and the plurality of carrying portions are made of a different material.
15. The device of claim 1 , wherein the plurality of wiring portions are made of an electrically conductive material.
16. The device of claim 1 , wherein at least one of the plurality of carrying portions is bent relative to its respective wiring portion.
17. A device comprising:
a plurality of wiring portions comprising at least one pitch adjusting portion between two adjacent wiring portions; and
a plurality of carrying portions such that at least one carrying portion protrudes from a respective wiring portion and is bent relative to its respective wiring portion.
