41. An illumination device comprising:
-
a waveguide; a light-emitting diode (LED), light emitted by the LED being in-coupled into the waveguide; and a sub-assembly providing mechanical support to the LED and disposed proximate a first surface of the waveguide, wherein, notwithstanding the presence of the sub-assembly, light from the LED is (i) confined by the first surface of the waveguide via total internal reflection and (ii) not absorbed by the sub-assembly. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
