WebApr 18, 2024 · With LEDs, the peak wavelength is variable and depends on the individual LEDs used when the UV lamp is manufactured. To make sure that an LED UV-A lamp produces fluorescence in penetrants and magnetic particle materials, the LEDs must have a peak wavelength within the range 360-370 nm. WebIn the case of GaN-based LEDs, there are two competing causes for wavelength shifts, current injection level, and junction temperature. The injection level effect causes the peak wavelength to shift to shorter wavelengths at higher currents. The temperature effect causes the peak wavelength to shift to longer wavelengths at higher temperatures.
