Claim of US Patent No. 10,925,132

1. A multipixel LED component comprising:a plurality of emission zones;
a plurality of conversion elements adapted to convert radiation emitted from the emission zones into radiation of another wavelength range;
a controller comprising a plurality of current sources and a transmitter adapted for wireless data transmission; and
two electrical contact structures through which the multipixel LED component is energized, wherein
the controller mechanically fixedly connects to the emission zones,
each of the current sources is assigned to one of the emission zones biuniquely,
the transmitter receives signals to control the current sources,
the current sources are controllable according to the signals,
each current source operates the emission zone assigned to it,
the number of emission zones is greater than the number of electrical contact structures,
the emission zones are part of a common LED chip, and
all emission zones comprise a common, continuous emission surface.
