摘要：
Proposed is a light emitting apparatus (1) comprising a light source (5) for emitting light and a collimator (40) for arranging the light emitted in an application specific distribution. The light source comprises (i) a semiconductor device (10) capable of emitting light, (ii) a body (20) having a bottom surface (21) adjacent to the semiconductor device (10) and an opposing top surface (22), and (iii) a reflector (30) positioned adjacent the top surface (22). The light emitting apparatus (1) is characterised in that the reflector (30) has a surface larger than the bottom surface (21) of the body (20). This is especially advantageous for creating a given light beam collimation with a smaller collimator or alternatively for creating a collimator producing a significantly narrower light beam.
