ENERGY-SAVING AND ENVIRONMENTALLY-FRIENDLY SOLAR STREET LAMP

摘要

An energy-saving and environmentally-friendly solar street lamp, comprising several lamp post units (1) connected to each other in an end-to-end manner; a lamp housing connection base (2) is fixedly connected to the lamp post unit (1) located at the top, and the lamp post unit (1) located at the bottom is detachably connected to a lamp base (9); a solar energy collection device (8) is mounted on the upper surface of the lamp housing connection base (2), and a plurality of lamp housing connection arms (3) and ultrasonic sensors (5) are connected to the lower surface of the lamp housing connection base (2); LED lamp heads (4) are mounted on the lamp housing connection arms (3); a storage battery and a microcontroller are provided in any lamp post unit (1); and the LED lamp heads (4), the solar energy collection device (8) and the storage battery are electrically connected to the microcontroller. Compared with the prior art, light sensors and ultrasonic sensors (5) are used for adjusting LED illumination, avoiding that street lamps always remain in full-power operation, and reducing resource waste; a plurality of lamp post units (1) can be sequentially connected to each other in an end-to-end manner, and can be flexibly mounted and fixed or dismounted, providing high stability; the matched use of lamp post fasteners (93) and a lamp post fastening cylinder (92) provides for rapid installation and fastening of lamp posts, and increases installation efficiency.
