The Basic Principles and Main Features of LED

Light-Emitting Diode(LED)is composed by the compound(gallium (Ga), arsenic (As)and phosphorus (P), nitrogen (N) compounds etc.) semiconductor material of the photovoltaic element, the core is a PN junction.

The principles are: when the forward voltage electrons from the N-region into the P region and holes from the P region into the N region,
part of the minority carriers into the area of the other side of the compound and shine with the majority carrier.


The color of the light is determined by the nature of the material of the PN junction.


The main features: low power consumption,high brightness, environmental friendly, long-life, small-size and so on.

As Xiamen G&H is a professional LED Components manufacturer, our products have RoHS certification and meet all environmental regulations and other rsequirements.
