Abstract (en)

[origin: WO2009039826A1] An optoelectronic component comprising the following features is disclosed: - at least one semiconductor body (1) provided for emitting electromagnetic radiation from a first wavelength range, - an inner radiation-transmissive shaped body (2), into which the semiconductor body (1) is embedded, - a wavelength-converting layer (6) on an outer side (5) of the inner shaped body (2), said layer comprising a wavelength conversion substance (8) suitable for converting radiation from the first wavelength range into radiation from a second wavelength range, which is different from the first wavelength range, - a coupling-out lens (10), into which the inner shaped body (2) and the wavelength-converting layer (6) are embedded, wherein - the coupling-out lens (10) has an inner side enclosed by an inner hemisphere area having a radius Rconversion, and an outer side enclosing an outer hemisphere area having a radius Router, and the radii Rconversion and Router meet the Weierstrass condition: Router = Rconversion * nLens/nair, where nLens is the refractive index of the coupling-out lens and nair is the refractive index of the surroundings of the coupling-out lens.
