How LED UV 3W Works

LED UV 3W operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in UV LEDs is usually a combination of gallium nitride (GaN), silicon carbide (SiC), or aluminum gallium nitride (AlGaN). These materials are capable of emitting UV light when an electric current is applied. The UV light emitted by LED UV 3W is highly efficient and has a narrow bandwidth, which makes it ideal for specific applications that require precise control over the UV wavelength. The efficiency of UV LEDs is measured in lumens per watt (LPW), and LED UV 3W can achieve LPW values of up to 60 lumens per watt.
