LEDs with a holder on the block are semiconductor components that are designed to convert the current passing through them into light radiation. Such light emitting diodes are manufactured in various versions (cases) for installation on certain blocks.
The principle of operation of LEDs with a holder is as follows: with the direct passage of charges through pn junctions of a pair of electric current carriers (holes and electrons), they break, while photons are emitted, and the electrons themselves go to neighboring energy levels.
LEDs come in a variety of shapes and colors.
