Abstract:

A lighting device (1) comprises a light source (2) and a lens (3, 23, 33, 43, 53, 63) positioned in front of the light source (2). The lens (3, 23, 33, 43, 53, 63) is provided with a light entrance surface on a side facing the light source (2) and a light exit surface (14, 38) on a side remote from the light source (2). The lens (3, 23, 33, 43, 53, 63) comprises a number of strip-shaped interconnected elongated light guiding elements (4, 24, 34, 54, 64), of which first ends (7, 27, 37, 57) and spaced apart second ends (5, 25, 35, 55, 65) comprise the light entrance surface and light exit surface, respectively. Light beams emitted by the light source (2) are transmitted by total internal reflection in the elongated light guiding elements (4, 24, 34, 54, 64) from the first ends (7, 27, 37, 57) to the spaced apart seconds ends (5, 25, 35, 55, 65).
