Wireless led power supply circuit diagram Using a transmitting coil 2 * 3cm, receiving the same size coil, the efficiency is about 58% when the distance is a few millimeters, and the efficiency decreases quickly with the increase of the distance, the efficiency is only 30% when it reaches 10 cm. I made 5W, but only used 20 LEDs, so I estimate that the power of 3W is enough. Have you done this kind of gadget in your spare time, come and exchange the results. This transmission method may be It will be useful in the future. It can be used to charge mobile phones and batteries in fully sealed products. I took a few pictures and sent them, the power can be more than 30W, of course, it can be increased, this is a demonstration Digital Load Cell,Electronic Load Cell,Load Cell With Digital Readout,Digital Load Cell Weight Sensor,load cell 5kg GALOCE (XI'AN) M&C TECHNOLOGY CO., LTD. , https://www.galoce-meas.com
Digital Load Cell is our new arrival load cells , digital output RS232 or RS485 , It made of aluminum alloy material, have 5kg, 10kg, 30kg , 40kg capacity and we recommend the max platform of it is 250×350mm.C4 high accuracy load cell, used for electronic counting scales, smart shelves, etc which needs high quality weighing condition.
