A frequent pain point for engineers is the unexpected "dimming" of UVC devices. Often, the LED chip is functional, but the organic packaging materials have failed due to high photon energy (4.4 to 4.8 eV).
-
The Yellowing Effect: UVC radiation breaks carbon-silicon bonds in organic silicones, causing rapid yellowing and reduced light extraction.
-
Hermetic Solution: All-Inorganic Hermetic Packaging uses a ceramic base, metal-to-glass Kovar seals, and quartz windows.
-
Long-Term Reliability: Eliminating organics ensures the optical path remains 100% transparent, enabling L70 lifetimes to exceed 10,000 hours.
