A light emitting device

A light emitting device 443 comprising:

• a flexible substrate comprising a longitudinal direction, a longitudinal axis (L) extending in the longitudinal direction, a transversal direction and a transversal axis (T) extending in the transversal direction, and
• a plurality of LEDs adapted for, in operation, emitting light, and being arranged on the flexible substrate in such a way as to extend in a longitudinal direction parallel with the longitudinal axis of the flexible substrate, each LED of the plurality of LEDs comprising a respective light output surface arranged facing in a main direction, the main direction extending perpendicular to both the longitudinal direction and the transversal direction of the flexible substrate,
• the flexible substrate being provided with at least one fold combination arranged in at least one predetermined position, the fold combination comprising at least two folds provided in such a way that the extension of the plurality of LEDs in the longitudinal direction is maintained and that
• the main direction in which the light output surface of at least one LED of the plurality of LEDs faces is rotated around the longitudinal axis of the flexible substrate over an angle θ with respect to the main direction in which the light output surface of at least one other LED of the plurality of LEDs faces, and
• the pitch between two adjacent LEDs of the plurality of LEDs is decreased, and
• wherein the fold combination with which the flexible substrate is provided comprises at least three folds provided in such a way that at least two surface segments of the same surface of the flexible substrate are brought into mutual contact, such that the main direction in which the light output surface of at least one LED of the plurality of LEDs faces is rotated around the longitudinal axis of the flexible substrate.
