LED LIGHT SOURCE AND ASSOCIATED STRUCTURAL UNIT
First Claim
1. An LED light source comprising a primary light source, in particular at least one blue- or UV-emitting semiconductor chip, the radiation of which is converted partly or completely into longer-wave radiation by a conversion element fitted at a distance, said conversion element being disposed as a dome ahead of the primary light source, wherein the dome is a section of an oblate body having an equator and a pole, wherein the pole points in the direction of the optical axis, wherein the oblate body is flattened in the direction toward the pole relative to the direction toward the equator, and wherein the oblate body is equipped with a converting phosphor layer.
