English term or phrase: LUMINESCENCE CONVERSION
In an LED, a solid-state crystal is induced to emit light by passing an electric current through it. The type of crystals used have two sections or regions: a region with a surplus of electrons (n-type semiconductor) and a section with a deficit of electrons (p-type semiconductor). When a direct voltage is applied, electrons flow across the junction between the two regions, generating light in the process.
The light thus created has a narrow-band emission spectrum which differs according to the semiconductor material used. White LEDs can be created by additive colour mixing or by luminescence conversion. Their colour temperatures are between 4,000 and 7,000 Kelvin and colour rendering index Ra around 70.
