A device comprising a flexible printed circuit strip is disclosed. The flexible printed circuit strip comprises a plurality of first sections connected to a plurality of second sections. The plurality of first sections are bendable in at least a first axis relative to the plurality of second sections. The plurality of first sections comprise a connector to house at least one light emitting element. The plurality of second sections comprises a protrusion with an opening between two adjacent second sections such that the protrusion is bendable in at least two axes. The plurality of second sections comprise a connector to connect an electrical power supply.

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.

Crimping of an LED leadframe to a subassembly may stress the leadframe. Flat leadframes cannot accommodate these stresses. Strain relief sections are added to the leadframe to accommodate crimping or other stresses on the leadframe. Strain relief sections are created in the leadframe in the form of openings, notches or bulges. The strain relief sections may be symmetric or asymmetric.

Strengthened LED package and method therefor

Embodiments of the present disclosure relate to a lighting strip, comprising a flexible printed circuit strip which comprises a plurality of wiring portions and a plurality of respective carrying portions, the wiring portions are used to supply electrical power to electric elements disposed on the carrying portions, and the carrying portions protrude from the wiring portions and are adapted to be bent around the wiring portions; a plurality of solid-state lighting elements respectively mounted on the carrying portions; wherein the wiring portion is provided with at least one pitch adjusting portion for adjusting a pitch between two adjacent carrying portions. Embodiments of the present disclosure also relate to a lighting device. According to the lighting strip and lighting device of the present disclosure, the positions of the solid-state lighting elements on the carrying portions, particularly the positions relative to the lighting elements, can be conveniently and precisely adjusted, thereby achieving a desired three-dimensional illumination shaping.
