FLICKERLESS POWER SUPPLY CIRCUIT OF LIGHTING APPARATUS FOR DESK AND LIGHTING APPARATUS FOR DESK HAVING FLICKERLESS FUNCTION

摘要

According to an aspect of the present invention, a converter circuit unit 110 rectifies an applied commercial power source to a direct current and converts it into a battery charging power source type to output a converted power source; A charging circuit unit 120 connected to the conversion circuit unit 110 for receiving the conversion power and outputting a charging power; A battery unit 130 which is connected to the charging circuit unit 120 and is charged according to a charging power applied thereto and outputs a driving power of a charged linear waveform; And a driving power of a linear waveform applied from the battery unit 130 according to an input signal of the switch unit 150 is connected to the LED module 221 by a circuit between the battery unit 130 and the LED module 221 And a driving circuit unit (140) for controlling the lighting and supplying the flickerless power supply circuit.
