Abstract: A wireless charging lighting device includes a charging transmitter and a charging receiver. The charging transmitter includes transmitter coil for transmitting power and a transmitter base for supporting the transmitter coil. The transmitter base includes two first positioning magnets. The two first positioning magnets are respectively placed on two sides of the transmitter coil. The charging receiver includes a receiver coil for receiving power, a fighting device electrically connected to the receiver coil, and a housing for packaging the receiver coil and the lighting device. Two sides of the receiver coil have a second positioning magnet, respectively. The magnetic attraction between the first positioning magnets and the second positioning magnets aligns the transmitter coil to the receiver coil.
