Vishay High-Power UV LED Designed For Long Lifetimes
365nm InGaN LED is an energy-saving replacement for mercury lamps
Vishay Intertechnology has introduced a new device in its VLMU35xx series of ceramic-based, high-power UV LEDs with silicone lenses that features a wavelength in the 365nm range.
Designed to provide a reliable, energy-saving replacement for mercury lamps, the Vishay Semiconductors VLMU3510-365-130 delivers long lifetimes in a 3.45mm by 3.45mm surface-mount package for medical, industrial, and printing applications.
The silicone lens of the VLMU3510-365-130 enables lifetimes up to 25,000h, compared to the typical mercury lamp lifetime of 10,000h. The LED is free of heavy metals and provides increased reliability with its shock resistance and immunity to degradation from frequent on/off switching.
While mercury lamps require complex drive circuits and need two to 15 minutes to warm up, the VLMU3510-365-130 allows for the use of simple low-voltage circuitry and requires no warm-up period.
Built on InGaN technology, the device released today features typical radiant power of 690mW at 500mA and 945mW at 700mA in a wavelength range between 362.5nm and 370nm. The VLMU3510-365-130 offers an emission angle of 130Â° and radiant intensity of 315mW/sr at 700mA.
The LED's specifications make it suitable for UV curing in nail salon, dental, and poster printing applications; blood and counterfeit money detection; and photocatalytic purification. RoHS-compliant, halogen-free, and Vishay Green, the VLMU3510-365-130 is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.
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
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.
