Abstract
The present invention provides an LED lighting device and a method for determining an operation time of the LED lighting device. The LED lighting device includes an LED module configured to emit light; an LED driver configured to supply power and drive the LED module; a micro controller unit (MCU) module that is connected to the LED driver and configured to measure an operation time of the LED lighting device; a display module that is connected to the MCU module and configured to receive the operation time sent from the MCU module and display the operation time; and a power supply module configured to supply power to the MCU module and the display module.
