What is the Typical Power Output of a UV LED Modules?
The power output of a UV LED module depends on its chip configuration, wavelength, drive current, optical design, and thermal management. In industrial UV curing and inspection, understanding the difference between electrical input power and optical output is essential for selecting a suitable light source. UV-LED Modules: What is the Power Output What is the typical power output of a UV LED modules? Regarding UV-LED modules, their power output ranges anywhere from 1 watts to 100 watts, and in some cases, even higher. These outputs are influenced by the configuration, application, and module type. There are various forms of expression used for measurement, such as: • Wattage (W) – consumption of electric power • Radiant Flux (mW or W) – optical or emitted power • Irradiance (mW/cm² or W/cm²) – power per area (important for curing or disinfection) Measurement Overview of Radiant Flux and UV LED 1. Radiant Flux Radiant flux can be measured in milliwatts (mW) or Watts (W). It is the output of light. Light output without distance consideration is called Radiant Flux. The measurement is made without considering the distance of the optical power. 2. Irradiance (mW/cm²) The energy detected striking a surface is called irradiance. This ...
