Referring to the operation of the digital lighting control system using the microcomputer control according to an embodiment of the present invention as described above are as follows.

First, when the external environment is dark due to weather or lighting, the amount of light detected by the illuminance sensor is weak. Thus, a small amount of current flows, and a high voltage is applied to the A / D converter 20 to digitally convert the light. The external illuminance is recognized by the microprocessor 30.

Accordingly, the microprocessor 30 may control the A / D converter 20 to control the resonant frequency for filtering the mixed state signal after the phase shift to a higher value according to the magnitude of the voltage data applied thereto. ), And at the same time, a control signal for increasing and setting the amplification factor is applied to the lamp driver 50.

By the setting process, the high frequency component of the lighting signal to be turned on is relatively more significant than the low frequency component and at the same time increases the overall illuminance, thereby setting the high illuminance to automatically adjust the illuminance.

Contrary to the above, when the external environment is bright, the microprocessor 30, which is sensed by the illuminance sensor and receives low voltage data digitally converted by the A / D converter 20, is reversed from the above process. By applying and setting a control signal for setting the resonance frequency to a low value by a program, and applying a control signal for reducing and setting the amplification factor to the lamp driver 50, the light to be turned on is set to low illumination and automatically illuminates the light.
