Exposing semiconductor chip to aqueous environments typically induces rapid galvanic corrosion, electrolysis, and catastrophic short-circuiting. Therefore, special protective solutions like bulky hermetic seals, quartz windows, or robust encapsulation, while necessary, often introduce significant thermal resistance and optical losses. According to Elphoton, the W2C® technology circumvents these limitations by fundamentally addressing the failure mechanisms at the electrode level. Through a proprietary electrode design and passivation strategy, the company has solved the...

UVC-LED technology is being highlighted as a key technology to replace conventional mercury lamps in the fields of water, air, and surface sterilization. Its importance became even more pronounced during the COVID-19 pandemic. However, when applying UVC-LEDs to real-world applications in the engineering field, we have consistently faced a critical technical hurdle. That hurdle is 'Reliability.' The primary applications for UVC-LEDs—such as water purifiers, HVAC (Heating, Ventilation, and Air Conditioning) systems, and home appliances&mdas...
