LED LIGHTING FIXTURE PROLONGING LIFE

摘要

PURPOSE: An LED device is provided to facilitate the maintenance and repair operations thereof by selectively operating two converters to supply power to a lamp. CONSTITUTION: A first converter(20) supplies driving power to an LED lamp. A second converter(30) supplies the driving power to the LED lamp when the first converter does not supply the driving power. A controller(40) includes a microprocessor. An output sensor(50) monitors the output state of the converter. A state display unit(80) displays the states of the first and second converters.
