Since COVID-19 pandemic in the world, UVC LED demand is raising. ProLight launched high power 100mW UVC LED and 1000mW UVC module for water Sterilization or air purify.

Currently, there are three main stream packaging technology used for UVC LED: 1. Organic packaging 2. Half inorganic packaging 3. Inorganic packaging. Due to the fact that UVC light will cause severe damage to the adhesive material within the LED package, therefore we have seen low reliability from LED products using organic packaging material in the market. More researches have been done and we came to realize that the key to better reliability is to improve the air tightness in packaging. In a half inorganic packaging, the glass lens is sealed onto the substrate by glue to form an enclosure in the package. But if the enclosure degrade overtime, there is the possibility that moisture will get inside the package and causing degradation in LED chip and the substrate, hence affecting the overall performance and reliability. Therefore, high quality UVC LED have now adopted the inorganic packaging approach. The main reason is that inorganic packaging material does not degrade from UV light, which means that there is minimal light degradation and also have little impact from moisture and heat stress overtime. This not only can maintain high performance of UVC LED, but improve the overall reliability.

ProLight UVC LED adopts exclusive Nano-quartz coating technology with inorganic packaging. Nano-quartz coating technology can protect chip from water vapor, humidity and air to improve reliability. UVC penetration rate is not blocked by Nano-quartz coating, it can maintain more than 99% penetration. ProLight UVC module with Nano-quartz coating tech to deliver 1000mW radiometric power output, which can be used for water Sterilization or air purify.

	Part No	Test Current @ Vf (typ.)	Radiometric Power
	PBLM-3CLU-TDA36A0C (265-280 nm)	600 mA @ 120V	1020 mW

Otherwise, ProLight adopts Germany high purity quartz, its high transmittance of UV light covers wavelength ranges from UVA to UVC, which is most suited for UV output. With narrow viewing angle (48° /60°) to deliver more focused power.

Inorganic packaging technology is a highlight for dome lens of ProLight UVC LED series. If it is not real inorganic packaging, the lens will be loosened under UVC irradiation, then loss of function.

This exclusive inorganic technology with Germany quartz lens can output higher radiometric power and high reliability.
