Everlight IRLEDs Power Remote Controls And Touch Panels

The 8.0 mW/sr@20 mA version can match or exceed 5mm IR diodes. This allows extended battery lifetime of handheld devices, or increased panel sizes
Everlight Electronics, a player in the global LED industry with three decades of experience in optoelectronics, has expanded its line of ‘invisible’ light sources.

The two new Surface Mount (SMD) infrared LEDs (IRLEDs), the IR26-71C and the IR26-61C, are suited for use in remote control applications.

The two IR26-71C models are 940 nm side-view devices that feature superior mechanical (height) and optical (radiant intensity and viewing angle) characteristics which make them ideal for use in remote controls as well as touch panels.

A height of just 1.2 mm allows the target devices to be as slim as possible, even when implemented into portables like mobile phones and tablets. With a radiant intensity of 5 mW/sr and 8 mW/sr or more at 20mA, they are claimed to outperform most SMD IRLEDs on the market.

The 8.0 mW/sr@20 mA version can match or exceed 5mm IR diodes. This allows either lower driving currents, to extend the battery lifetime of handheld devices, or increased panel sizes which lengthens the transmission distance of remote controls. A viewing angle of 50° ensures that the remote control does not need to be directly pointed towards the receiving device, but instead works in a wide operating range.

Based on a similar package design, Everlight is offering the IR26-61C IRLED series with a narrower viewing angle of 20° and the PT26-71B phototransistor series. These are both matching pairs designated for small-middle (5 - 32") size optical touch panel applications. Due to the same low height of 1.2 mm, the slit for the touch panel’s optical frame can be kept very small, thus allowing the device to be slimmer and have a higher quality appearance.

Samples are available upon request and are now in mass production.


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.
