Epistar Unveils Photoelectric Efficient 850nm LED

The infrared III-arsenide based chip is claimed to have set new records in the LED industry
Lots of forward-looking technologies have been well developed and now applied to LED chip production.

These include novel transparent conductive thin films, compound mirror structures, and new EPI structure designs for reducing the absorption of light.

These innovation technologies will raise the light extraction efficiency and LED performance.

Recently, Epistar Lab made an amazing improvement on the infrared products and believes it has set new records in the LED industry.

According to the latest data depicted in the graph below, the infrared product SFPN42 (chip size 1 x 1mm² ) achieved wall plug efficiency of 75 percent with an operating current of 40mA and of greater than 70 percent at 350mA; the power even exceeds 1W and has reached 1027mW with the operating current of 1A.

Such an impressed efficiency development has made LED chips more energy saving and eco friendly.

Now the infrared products are mostly adopted in the security monitor, smart touch panel and wireless communication systems. In the future, Epistar wants to use these products in other high potential markets to keep the competitive strength of its customers.


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.
