Definitions

  • FIG. 1 is a block diagram schematically illustrating such design, wherein the current source 1 is implemented as a conventional copper-iron ballast having input terminals 2 for connection to mains, an inductive impedance 3 and a rectifier 4 arranged in series. A first string 11 of LEDs is connected between output terminals 5 and 6 of the rectifier 4.
  • Figure 1 is a block diagram schematically illustrating a conventional way of powering LEDs, having a string of series-connected LEDs connected between the output terminals of a current source;
