Title:
LED LIGHTING DEVICE FOR PREVENTING FLICKERING
Document Type and Number:
WIPO Patent Application WO/2019/083110
Kind Code:
A1
Abstract:
The present inventions presents an LED lighting device for preventing flickering. The device comprises: a rectification unit receiving an alternating current voltage applied from an alternating current power source and rectifying the same so as to output a direct current; a first light-emitting unit receiving the direct current applied thereto and adjusting a first constant current so as to make a first LED array emit light; a second light-emitting unit receiving the adjusted first constant current applied thereto and adjusting a second constant current so as to make a second LED array emit light; and a serial switching unit receiving the direct current and the adjusted first and second constant currents applied thereto so as to control current transmission according to the opening/closing of a plurality of embedded transistors, wherein the direct current and the first constant current, which are to be applied, are applied by passing through first and second diodes, respectively.
