Abstract
A light emitting diode device is provided and includes a first light emitting diode(LED) package emitting light to generate a first brightness. The first LED package includes a first diode being driven in response to a pulse width modulation (PWM) current to generate a first portion of the first brightness and a second diode being driven in response to a first direct current (DC) current to generate a second portion of the first brightness. In a first operation mode of the LED device, the first diode and the second diode are enabled to make the first brightness to reach a first value. In a second operation mode, different from the first operation mode, of the LED device, the second diode is disabled to reduce the brightness from the first value to a second value.
