Abstract: The present invention is directed to a front light extraction tape (22) for coupling light (10) out of a light guiding device (16). The tape (22) has a flexible, light transmissive outer portion without using adhesive. An input surface (28) of the light coupling element (26) is contactable with an output surface (24) of the light guiding device (26) for receiving light therefrom. A reflecting surface (32) of the light coupling element (26) is aligned so as to reflect light received into the light coupling element (26) through the light transmissive outer portion (24). The light coupling element (26) may be formed integrally with the outer portion (24) so as to avoid a material interface between the light coupling element (26) and the outer portion (24).
