Transformers consist of two connected coils that generate electricity. That electricity is how the LED emits light. One coil is connected to the light's power source. The primary coil picks up electricity from the power source, sends it the other coil, andÊthat coil sends electricity to the light itself. The connection between the two coils determines the voltage generatedÊand the LED transformer can increase or decrease the amount of voltage that runs into it. The measure of this change is the turns ratio. ...Read More
