Abstract
A light emission device includes: a plurality of semiconductor light-emitting elements; an optical element configured to collimate light emitted from each of the plurality of semiconductor light-emitting elements and output a plurality of collimated beams; and a paraboloid reflector configured to be irradiated with the plurality of collimated beams. The plurality of collimated beams reflected by the paraboloid reflector are converged.
Claims14
A light emission device comprising:
- a plurality of semiconductor light-emitting elements;
- an optical element configured to collimate light emitted from each of the plurality of semiconductor light-emitting elements and output a plurality of collimated beams;
- and
- a paraboloid reflector configured to be irradiated with the plurality of collimated beams at a region avoiding a vertex of the paraboloid reflector, and to cause the plurality of collimated beams reflected by the paraboloid reflector to converge onto a focusing point, wherein:
- in a plane that is perpendicular to an axis of a paraboloid of the paraboloid reflector and includes the focusing point, a reflective surface of the paraboloid reflector forms a single curved line.
