At this time, if the external illuminance is higher than the unlit illuminance starts the extinction (S420), otherwise checks whether the 'S410', the external illuminance is less than the illuminance (S430). If the external illuminance is less than the illuminance (S430), the lighting is started (S440), otherwise (S430), the 'start mode' operation ends.
- FIG. 7 is a flowchart illustrating an operation mode operation flow of a street lamp automatic flashing control method according to the present invention.
- the automatic street lamp blinking control apparatus is in the operation mode operation state when the current state is a lighting state (S500), and then, if it is a lighting holding time (S510). If the dimming time is checked (S570), the dimming output is controlled (S580), and if the dimming time is not (S570), the process is completed.
- the current state is not in the lit state (S500)
- check whether the current time is the lit standby time (S590). If the present time is the lighting standby time, the lighting is waiting (S600), if the external illuminance is less than the lighting illuminance (S610), the lighting standby is terminated (S620), the lighting is started (S640). At this time, the lighting is maintained for the lighting holding time.
- FIG. 8 is a flowchart illustrating a switching mode operation flow of the method for automatically controlling a streetlight blinking according to the present invention.
- the automatic street light blinking control apparatus checks whether a day is present by detecting a current time when operating in a 'switch mode' (S700). If the current time is a low time (S710), the lights are turned off, so that the lights out for the remaining burn out maintenance time (S720).
- the current time is not the day time (S710)
- the current time is not night time (S730)
- the waiting for lighting is terminated (S770), and lighting is started (S790). At this time, the lighting is maintained during the lighting holding time.
- the present time point is not the lighting standby time in the 'S750' process, it is compared to the external illuminance and lighting illuminance as the extinguishing waiting time (S800), when the external illuminance is higher than the illuminating illuminance (S800), the light-off waiting is terminated (S810), turn off (S830). At this time, the lights out to maintain the lights out during the maintenance time.
- the operation mode is switched to the 'driving mode' (S840), and the process enters FIG. 4A to perform a subsequent process.
