Introduction

Adding LED lights to anything makes it 5 times better — that's a scientific fact! But when you have LED lights, you have wires and power supplies, all of which are quite annoying. What if you could have LEDs that light up without any wires, soldering, or battery packs? Sounds magical! That's what makes this kit of 10 large wireless LEDs so clever. When paired with a large inductive coil kit, they use electromagnetic fields and inductive coupling to transfer power through the air, lighting up LEDs soldered onto the coil. Each order includes ten red large LED inductors. Compared to the smaller red wireless LEDs, the large ones can operate at greater distances, especially when used with a large coil. Inductive charging is a way to power devices without direct wire connections. Most people have seen inductive charging in rechargeable electric toothbrushes: you may have noticed they charge by being placed in a stand, with no direct plug. These chargers work by splitting a power transformer into two halves — an AC waveform is generated into one coil and coupled to a second coil. In this product, one coil forms the 'primary' of the power charger. Each individual LED then has a smaller coil on its back. When the two are coupled, power transfers from the coil to the LED, causing it to light up. You can have a large number of LEDs, all positioned at different points in three-dimensional space above or below the coil. You can also have them in different orientations, though you will achieve the greatest efficiency/power transfer when the two coils are aligned. You can also position the LEDs slightly outside the main ring, though they won't be as bright as when centered directly over it.
