And ‘it born Marina. The wireless LED lamp. Thanks to Futura Electronics, Electronics IN and Open-Electronics, we were able to achieve this prototype of 3D printed LED lamp with a wooden base.
The contest, organized by Open-Electronics is giving away a wireless power kit with which to build the prototype. We modeled the lamp and printed 3D structure. The base of wooden recharge has been laser-cut. Inside the base there is a rechargeable battery and a switch. The experience of use of the lamp is amazing. Just bring it closer to the base and see it illuminate the environment. The print is totally non-toxic material. The consumer is really very low, since the high-brightness, low-power LEDs.
The wireless power kit supplied by Future Electronics and IDT, Würth Elektronik, Open-Electronics, has multiple uses, such as battery chargers, or power supply. We are very happy to have discovered this interesting kit, and surely we will use to create other prototypes.
The lamp operation is very simple. Simply place the lamp base, powered by batteries, to see the LED light up, and change its brightness according to the position. The lamp is very light, because without a battery or power supplies. The centerpiece of the electronic project is in the power base. The electrical connections are simple. The emission circuit is connected to the battery through a switch, and the receipt is inserted into the structure of the lamp connected to a 3W LED.
The wireless kit consists of two modules. The transmitter and the receiver. The first based on the integrated P9038 can be powered with a constant power supply 5V 2A. When the connection between the two modules is established, and shirt the passage of energy, the LED on the transmitter module will light green indicating the correct coupling.
For our project we used the VIN and GND pins on the wireless transmitter module, connecting them to the battery, and pin and OUT and GND on the receiver module by connecting to the led.
