Abstract:
1. An illuminating device, comprising: (a) a shell having: (b) a portion of the shell having an advertisement, insignia or mark disposed on or embedded into at least one of the outer or inner surfaces; (c) a light source disposed at the first end for emitting light into the waveguide between the outer and inner surfaces so that a substantially larger portion of the light propagates along the longitudinal axes of the shell from the first end to the second end by multiple total internal reflections between the outer and inner surfaces, and a substantially smaller remaining portion of the light partially leaks due to frustrated TIRs through at least one of the outer or inner surfaces having the advertisement in a direction, which is lateral to the longitudinal axes of the shell; and (d) a light scattering element optically coupled to the waveguide and disposed substantially at the second end for distributing the portion of the light reaching the second end substantially along a direction of the longitudinal axis of the shell into a spatial angle outside of the shell near the second end of the shell.
