LED lights
How do LED lights work?

LED lights work when a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This is how LED lights work.

What energy transfers occur in a LED light bulb?

The energy transfers that occur in a LED light bulb is electrical energy that transfers into light energy and heat energy.

How does it allow efficient energy transfer?

LED operates by having a small amount of input electrical energy and releases more than twice that energy in ultraviolet light. This means more than 200% efficient energy transfer is allowed.
