An LED chip is a light-producing semiconductor device that may or may not be incorporated into a light emitting diode (LED).
The chip is manufactured onto a heat-conducting material and then covered by a glass or plastic lens.
An LED chip is so small, you could fit almost six LED chips on the tip of a baby’s fingernail. The amount of light that is produced by these little conductors is really amazing. They are only getting smaller and brighter and engineers are constantly working on making them last even longer.
