Streetlight dimming control method for reducing power consumption and streetlight

摘要

The present invention relates to a method for controlling dimming of a streetlamp to reduce power consumption. In the method for controlling the dimming of the streetlamp, the streetlamp comprises a plurality of illumination units, of which dimming can be individually controlled, and at least one illumination unit among the plurality of illumination units has a wattage smaller than that of another illumination unit. According to the present invention, a plurality of LEDs included in a streetlamp are randomly divided according to the direction of progress of a vehicle and dimming of the divided LEDs are controlled with different levels, so that luminance degradation felt by a driver on a road can be minimized. As a result, the present invention can save energy and solve inconvenience to the driver.
