A lamp includes a lamp body, a control module and a solar energy collector. The solar energy collector includes a first motor, a second motor coupled to the first motor, a solar energy absorption board, and a detection apparatus mounted on the solar energy absorption board. The solar energy absorption board coupled to the second rotary rod. The detection apparatus includes two first photosensitive resistors mounted opposite to each other and two second photosensitive resistors mounted opposite to each other. The control module controls the first motor to rotate when a voltage difference between the first photosensitive resistors is detected; the control module controls the second motor to rotate when a voltage difference between the second photosensitive resistors is detected.
