A lighting device, comprising at least one solid state light emitter and one (or more) optical device(s) which (each) comprises at least first, second and third optical structures, first and second surfaces of the second structure being in contact with a surface of the first structure and a surface of the third structure, respectively. The third structure has at least one optical feature. The light emitter is positioned, the optical feature is positioned, and the regions of the structures have indices of refraction, such that if the light emitter is illuminated, at least a portion of the emitted light will enter into the second optical device structure and exit from the optical feature on the third structure. Also, a method of lighting comprising illuminating a light emitter in such a device.
