Abstract:
There is proposed a light source comprising: a semiconductor diode structure adapted to generate light; and an optical enhancement section above the semiconductor diode structure and adapted to output light from the semiconductor diode structure. A partially-reflective layer covers at least a portion of the top of the optical enhancement section and is adapted to reflect a portion of the output light towards the optical enhancement section. The partially-reflective layer has a light transmittance characteristic that varies laterally.
