Taiwan–TSLC Corporation, leading manufacturer of LED components and OEM/ODM service provider, announced sampling of its ultraviolet C (UVC) product lines. TSLC provides high power and ultra high density UVC LEDs ranging from single chip to multiple chip packages, targeting to provide sterilization and aseptic markets with high power options greater than 500mW.
Currently, market available UVC package technologies involve the LED chips protected in a glass or quartz glass protected air cavity. This is the not most efficient optical design. The differences in refractive index between the semiconductor layer, air and optical material (ie glass or quartz glass) causes UV radiation to be trapped within the chip and the cavity. TSLC’s new UVC LED product series uses a high refractive index material, high UVC transmissible, to increase the light extraction by about 35%. TSLC’s UVC series consists of LED packages of variable footprints and power consumption. The product lineup includes single, 4- (four) and 10 (ten)-chip packages.
“The 10-chip package was specifically designed with options for customization.” TH Lin, the Vice President of Sales and Marketing Department of TSLC Corporation, explained, “This is a 3.6 by 10.0 millimeter emitter of which we could put as many as ten UVC chips with minimal chip pitch to enable optimized light density. The package provides a solution for industrial applications where high UVC radiation is needed.” The LEDs’ small footprint and flexibility was another intentional design concept. Mr. Lin further explains, “The emitter was designed to incorporate ten UVC LED chips, but the package allows for customization in chip count from 2-10 chips. This emitter is surface mountable and can be easily modularized to needed beam shape.”
Due to the increasing demand in UVC light sources, TSLC is also providing design and manufacturing services for customers that are looking for customized UVC modules. The company has the ability to customized emitter and/or chip-on-board solutions. TLSC will also provide or assist our customers with assist with electrical, thermal, and optical designs at the module and system levels to enable our customers’ applications.
