LATERALLY-EMITTING, RADIATION-GENERATING COMPONENT, AND LENS FOR ONE SUCH COMPONENT

Optical appliance contains reflective surface, of U-shaped cross-section, and convex refractive surface, when viewed from outside, between reflective surface and bottom, facing radiation source, that is so structured and located that it couples electromagnetic radiation of source into optical appliance.Reflective surface is so shaped and positioned that central part of coupled radiation is deflected to refractive surface, that is of such structure, as to output coupling radiation from reflective surface and source, laterally to source, as radiation beam. Independent claims are included for lens for invented component.
