The invention relates to a light system with increased efficiency, based on a separate converting layer (6), said system comprising at least two different types of chip (2, 3), the radiation of a first type of chip (2) being at least partially converted by the conversion layer. The radiation of the second type of chip (3) has a longer wavelength than that of the first chip, the second chip being arranged in such a way that the radiation thereof is essentially not absorbed by the illuminant.
