Floating solar energy navigation lamp

The utility model discloses a floating solar energy navigation lamp comprising a floating part, a lamp post, light sources, a solar energy panel, a control device, a sensing device and a storage battery. The light sources are arranged on the top part of the lamp post; the floating part is mounted on the bottom of the lamp post and comprises an opening part and an accommodating part; the solar energy panel is mounted on the floating part and covers the opening; the control device and the storage battery are accommodated in the accommodating part; the storage battery is electrically connected with the light sources; the sensing device is mounted on the lamp post; the control device is formed by a central processor and a light source driving circuit; the sensing device senses strength of light rays and sends a signal to the central processor; the central processor receives the signal and processes the same; the processed signal is then sent to the light source driving circuit; and the light sources are controlled to brighten and die out by the light source driving circuit based on the received signal. In the floating solar energy navigation lamp, the solar energy is converted into electric energy via the solar energy panel, so the light sources are powered and a problem of inconvenience of power supply maintenance in the prior art is solved.
