Zusammenfassung:A lighting apparatus 10 comprises a waveguide 18 and a lighting device 28 at an end of the waveguide. The waveguide 18 is capable of sustaining total internal reflectance and has a printed reflector 26 on its surface to reflect light from the waveguide. The lighting device 28 has at least one LED 15 to emit light into the end (39, Fig. 2) of the waveguide 18. A gap (38, Fig. 2) is provided between the LED 15 and the end 39 of the waveguide 18.
