LAMP EXCITING METHOD AND DEVICE Russian patent published in 2015 - IPC H05B37/02 

FIELD: electricity.

SUBSTANCE: invention relates to lighting engineering. The lamp exciting method and device (2) includes stages whereat: electric current of the lamp is generated (Iconst) with constant value; commutation period is preset with duration equal to Tcomm; time-base sweep is preset for initial moments of commutation with fixed mutual intervals of 0.5xTcomm; data to be outputted at the light output are received; electric current of the lamp is commutated at commutation moments; at that separate commutations are time-modulated in order to code the above received data. The commutation moment shall be preferably: either equal to the initial moment of commutation when there are no data to be outputted or advanced per modulation interval (Δ) in regard to the respective initial moment of commutation for coding of data having the first value ("0") or delayed per the above modulation interval (Δ) in regard to the respective initial moment of commutation for coding of data having the second value ("1").

EFFECT: increased data processing rate during data coding to output light generated by the lamp.
