LED LIGHTING DEVICE Russian patent published in 2020 - IPC H05B33/08 

FIELD: lighting.

SUBSTANCE: invention relates to a light-emitting diode (LED) lighting device and a method for driving a LED lighting device. Result is achieved by the fact that LED lighting device (1) comprises LED load (10) containing a certain number of LEDs (100); input contacts (14_hi, 14_lo) for connection with power supply (2) configured to supply input voltage (U_PS) at primary input voltage level (V_PS); voltage rise module (11) configured to increase input voltage (U_PS) to a level higher than the level (V_PS) of the primary input voltage based on input signal (30) of the light intensity adjustment level; and a light intensity control module (12) configured to reduce the current (I_LED) of the LEDs through LED load (10) when the boosted input voltage (U_boost) exceeds the (V_PS) of the primary input voltage.

EFFECT: technical result is providing adjustment of light intensity of LEDs of lighting device.
