The utility model discloses a
buoy high lamp which comprises a
buoy shell, a hanging ring is installed in the
buoy shell, a circular ring of the hanging ring is located at the top of the buoy shell, other parts of the hanging ring are fixed in the buoy shell, a PCB is fixed in the buoy shell through resin glue, and the PCB is fixed in the buoy shell through a
light source. A switching circuit, a
voltage stabilizing circuit, a charging
control circuit, two groups of
infrared lamp beads, namely, a 940-nanometer
infrared lamp bead and an 850-nanometer
infrared lamp bead, a charging indicator lamp, a rechargeable battery and a magnetic charging seat are arranged on the PCB, the magnetic charging seat is welded on the PCB, and three electrodes are arranged on the magnetic charging seat. The buoy high lamp has the advantages that the buoy water entering
signal detection
electrode is matched with the switch circuit, a
closed circuit is formed after water entering, the
infrared lamp bead is turned on, an open circuit is formed after water exiting, and the
infrared lamp bead is turned off, so that the purposes of prolonging the service life of the buoy high lamp and saving energy are achieved.
