<p>PURPOSE: A self-generation sunlight tracking streetlight is provided to improve sunlight concentration efficiency by rotating a solar panel according to the movement of the sun. CONSTITUTION: A solar panel actuator(100) rotates a solar panel according to the movement of the sun. An LED lamp(200) is mounted on a streetlight support frame. The LED lamp is operated with the power from a solar power charger. A system control module(300) distributes the power from the solar panel actuator and the solar panel to the LED lamp and an LED color display unit(400). The system control module selects one of a sunlight tracking mode, an LED lamp driving mode, and an LED color display mode according to the position of the sun and surrounding illumination.</p> |
