Example two

The touch wireless charging desk lamp provided by the embodiment is different from the first embodiment in that:

as shown in fig. 5-7, the wireless charging coil of the present embodiment is a microwave wireless transmitter 1, and the present embodiment further includes a microwave wireless receiver 2; the lamp holder is connected with a bulb such as an LED lamp (not shown in the figure) and is connected with an LED lamp control circuit of the base; the microwave wireless transmitter 1 is arranged in the base A.

Specifically, although the microwave wireless transmitter 1 is widely used at present, compared with an electromagnetic induction type resonant coil, the microwave wireless transmitter still has a relatively large volume due to the fact that a current conversion microwave circuit, a transmitting antenna and even an amplifying and adjusting circuit of microwave power are integrated in the microwave wireless transmitter, the microwave wireless transmitter is arranged at the lowest end in the base A, the area of the chassis is enlarged in a matched mode, the microwave wireless transmitter is slightly interfered by an obstacle, the signal intensity is not affected, and meanwhile the microwave wireless transmitter can be used as a load-bearing stable chassis. The microwave wireless receiver 2 is provided with a charging connection line 22 for connecting with a device to be charged, so that the microwave wireless receiver 2 can be prompted to be available when the desk lamp is powered on. Specifically, the microwave wireless receiver 2 serves as a connection end with a mobile phone waiting charging device, an array antenna 21 and a microwave conversion current circuit are arranged in the microwave wireless receiver, the array antenna 21 receives microwaves transmitted by the microwave wireless transmitter 1, the microwave conversion current circuit converts the received microwaves into current signals, and the electric energy is transmitted to the waiting charging device through a charging connection line 22 such as a USB data line, so that charging is achieved. The microwave wireless receiver 2 can also be internally provided with a power supply, a resonant coil and a wireless transmitting resonant circuit which are adapted to a device to be charged without a charging port.
