LINEAR POSITIONER Russian patent published in 2019 - IPC H05B33/08 

FIELD: lighting.

SUBSTANCE: invention relates to lighting devices. Result is achieved by the fact that linear controller (1), which is implemented for use in LED lighting device (2), comprises cascade (L1, L2, L3) of control circuits, implemented for connection between output of LED lighting load (20) and converter (21) power of LED lighting device (2); transistor (Q), implemented for current control (I_LED) of LEDs through LED lighting load (20); first input (11) for connection to input signal (I_supports) of reference current; second input (12) for connection to input signal (V_supports, ΔI_supports) of operating parameter; and output for connection of output signal (P_OCR) controlling power of linear controller (1) with power converter (21); wherein cascade (L1, L2, L3) of control circuits comprises at least two interconnected control circuits (L1, L2, L3) for current control (I_LED) of light-emitting diodes on the basis of input signal of reference current (I_supports) and adjustment of additional operating parameter of LED lighting device (2) based on input signal of operating parameter (V_supports, ΔI_supports).

EFFECT: technical result is reduction of post-adjustment loss to minimum, while simultaneously providing possibility of corrected trade-off between size of capacitor and flicker at light output.
