A few days ago, Vishay Intertechnology, Inc. (NYSE stock market code: VSH) announced that two new types of ceramic/quartz base materials UVC (short-wave ultraviolet) light-emitting diode --- VLMU35CR40-275-120 and VLMU35CR41-275-12020 , Electronic and Consumer Electronics Application. Vishay Semiconductors Vlmu35CR40-275-120 and VLMU35CR41-275-120 light light intensity is higher than the previous generation solution, while reducing costs, suitable for efficient disinfection, and has a longer service life.

The device released a few days ago is under 250 mA conditions. The typical light power is 37 mW, and the cost performance of MW/$ is higher than the low -power light -emitting diode 30 %, which is better than the previous generation solution 12 times. In addition, VLMU35CR41-275-120 is under 250 mA conditions, the minimum lighting power is 30 mW, which is equivalent to the light intensity at the condition of close-up competitive devices.

The wavelength range of light emitting diode is 265 nm to 280 nm, and the typical wavelength is 274 nm. It is not only suitable for direct disinfection of surface, air and static water, but also compared with the 280nm solution, VLMU35CR40-275-120 and VLMU35CR41-275-120 increased disinfection efficiency by 20% by 20% Essence The device adopts 3.45 mm x 3.45 mm x 1.7 mm small surface packaging with excellent heat dissipation performance. It is equipped with ceramic substrate and quartz window, 250 mA, and 27,000 hours under the conditions of 25 ° C.

VLMU35CR40-275-120 and VLMU35CR41-275-120 are based on ALGAN technology and are specifically used to replace low-pressure UVC mercury lamps, especially suitable for small and compact designs of devices. Typical terminal products include earplugs, toothbrushes, water bottles, refrigerators, air purifiers, door handles, medical devices, coffee machines, automatic cash machines, toilet seats, vacuum vacuum cleaners and other disinfection devices.

Device DC positive current reaches 300 mA, the forward voltage is as low as 5.2 V, and the emitter angle is ± 60 °. VLMU35CR40-275-120 and VLMU35CR41-275-120 meet ROHS and Vishay Green Standards, halogen-free, suitable for reinventing welding technology, and the humid sensitivity level reaches the J-STD-020 standard 3.

The new UVC light -emitting diode can now provide samples and mass production, and the supply cycle is 16 weeks.
