The invention discloses a light-emitting
diode (LED)
candle lamp and the swinging principle of a light-emitting sheet of the LED
candle lamp. The LED
candle lamp comprises a casing, a casing core arranged in the casing, a light-emitting
assembly and a battery box arranged at the bottom of the casing. The light-emitting
assembly comprises the light-emitting sheet, a lens and a support, wherein the support is fixed on the casing core, an LED
chip is arranged on the lens, and a
magnet is connected at the bottom of the light-emitting sheet. A power supply driving plate is arranged on a top cover of the battery box and is matched with the
magnet of the light-emitting sheet through an
electromagnet to form a
flame swinging mechanism. The swinging principle in that: an
electromagnetic coil is driven and led to generate a
magnetic field with corresponding change, polarity of the direction of the
magnetic field is identical to that of the direction of the
magnet at the bottom of the light-emitting sheet, repulsive force changing along with square
waves is generated, and the light-emitting sheet is led to swing randomly under effects of electromagnetic force and self gravity. The LED candle lamp is small in
electricity consumption and generated heat, is completely free of potential safety
hazard, cannot cause energy waste, achieves effect of environment protection, and is suitable for being widely used by people.
