Devices Provide Energy-Saving Replacement for Mercury Lamps in Medical, Industrial, and Printing Applications

Vishay Intertechnology has introduced the first two devices in a new series of ceramic-based, high-power UV LEDs with silicone lenses. Designed, the company says, as energy-saving replacements for mercury lamps. The Vishay Semiconductors VLMU3500-385-060 and VLMU3500-385-120 claim to deliver exceptionally long lifetimes in compact 3.5 mm by 3.5 mm surface-mount packages for medical, industrial, and printing applications.

The environmentally friendly UV LEDs are free of heavy metals and provide increased reliability with their shock resistance and immunity to degradation from frequent on/off switching. The VLMU3500-385-060 and VLMU3500-385-120 allow for the use of simple low-voltage circuitry and require no warm-up period.

Built on InGaN technology, the devices released feature typical radiant power of 780 mW at 500 mA and 1037 mW at 700 mA in a wavelength range between 380 nm and 390 nm. The devices provide radiant intensity of 730 mW/sr and 390 mW/sr at 700 mA, respectively.

Samples of the new UV LEDs are available immediately. Production quantities are available with lead times of six to eight weeks.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
