Abstract
An input lighting signal optimization device includes a multiplex circuit configured to select and output a first LED lamp lighting signal or a second LED lamp lighting signal, and a MICOM configured to output a driving signal for driving a first LED lamp or a second LED lamp after receiving an output signal of the multiplex circuit through one input port and detecting a wake-up signal included in the output signal of the multiplex circuit to switch to an activation mode.
Claims16
An input lighting signal optimization device comprising:
- a multiplex circuit configured to select and output a first LED lamp lighting signal or a second LED lamp lighting signal;
- and
- a MICOM configured to output a driving signal configured to drive a first LED lamp or a second LED lamp after receiving an output signal of the multiplex circuit through an input port and detect a wake-up signal included in the output signal of the multiplex circuit to switch to an activation mode.
An input lighting signal optimization method comprising:
- a power saving mode in which a MICOM receiving an output signal of a multiplex circuit configured to select and output a first LED lamp lighting signal or a second LED lamp lighting signal through one input port operates in a power saving mode if the output signal is not inputted s to the input port for a predetermined period of time;
- a wake-up operation of detecting a wake-up signal from the output signal inputted to the input port and operating in an activation mode;
- and
- a driving operation of outputting a driving signal configured to drive the first LED lamp or the second LED lamp as a function determined for each voltage level after recognizing a voltage level of the output signal inputted to the input port.
