ABSTRACT:
A solar energy street lamp structure with an adjustable angle is provided. The solar energy street lamp structure includes a lamp holder, a lighting unit, a photovoltaic panel, an electric power storage portion, and an actuation portion. A frame and a holder of the lamp holder are movably coupled by pivot units. The electric power storage portion is placed inside the lamp holder. An actuation unit of the actuation portion is connected between the frame and the holder for adjusting an angle between the frame and the holder such that the lighting unit and the photovoltaic panel, both disposed on the holder, are adjustable synchronously. The photovoltaic panel and the lighting unit are rotatable according to an incident angle of sunlight by adjusting the holder. Thus, the solar energy street lamp structure generates power at enhanced efficiency and can emit light in various directions so as to have wide applicability.
