In one embodiment, the invention provides an LED module, having a carrier, a first group and a second group of LED chips arranged on the carrier, optionally one or more further groups of LED chips, and a layer covering all LED chips and containing at least one colour conversion material, which converts the spectrum of the LEDs of one or all groups into a spectrum with a different dominant wavelength. Every group comprises at least one LED chip, preferably a plurality of LED chips. The LED chips of one group are preferably connected in series and can be supplied starting from the same electrical supply. The LED chips of different groups can be supplied independently of one another, starting from different electrical supplies. |
