<p>PURPOSE: A dimming monitoring control method of a light emitting diode (LED) street lamp is provided to determine the degree of precision by blocking the noise of switched-mode power supply (SMPS) and measuring a current. CONSTITUTION: A dimming signal is received (S100). A current control signal corresponding to the dimming signal is outputted (S200). The current control signal is outputted to a power supply device of an LED street lamp (S300). A hall voltage corresponding to a sensed current is outputted (S400). A driving condition of the LED street lamp is determined based on the hall voltage (S500). [Reference numerals] (AA) Start; (BB) End; (S100) Receive a dimming signal; (S200) Output a current control signal corresponding to the dimming signal; (S300) Output one of multiple current control signals to a power supply device; (S400) Output a hall voltage corresponding to a current provided to an LED street lamp; (S500) Determine a driving condition of the LED street lamp based on the hall voltage; (S600) Transmit an operation status</p> |
