Abstract

An LED module, selectively comprising at least zero, one, or a plurality of LEDs from Group B and/or Group G and/or Group R and at least one or more LEDs from Group P. The concentration of phosphors/phosphor mixtures of the LEDs in Group P is selected such that the photometric efficiency (lm/W) thereof is at or near the maximum as a function of the CIE x-coordinates.
