<p>In a method for coupling light sources to a light guide, the light sources (4) are non-radial and they are coupled to the light guide (1) in such a way that the main axis of the far-field of the light sources (4) is substantially parallel to the tangent of the curve of the cross-sectional form of the light guide (1). The light sources (4) are semiconductor lasers.</p> |
