FLEXIBLE LED LIGHTING STRIP WITH SLANTED LEDS
First Claim
1. A flexible lighting strip for use in a vehicle signaling light comprising:
- a multitude of light-emitting diodes,wherein the flexible lighting strip is arranged to be bended around at least two, more preferably three linear independent axes,wherein light-emitting diodes of at least a first group of the light-emitting diodes are inclined with respect to a longitudinal extension of the flexible lighting strip such that surface normals of light exit surfaces of the first group of the light-emitting diodes enclose a first angle of more than 0°
with corresponding surface normals of a light emission surface of the flexible lighting strip,wherein the light-emitting diodes are mounted on a carrier structure,wherein the carrier structure is arranged to incline the light-emitting diodes with respect to the light emission surface of the flexible lighting strip, andwherein the carrier structure is arranged such that the angles between the surface normal of a light exit surface of a first light-emitting diode and the corresponding surface normal of a first part of the light emission surface associated with the first light-emitting diode increases with increasing curvature of the first part of the light emission surface.
