Lextar To Debut `White Chip` LED

The III-nitride based module is claimed to have an efficiency of 200 lumens per Watt
Lextar Electronics, a vertically integrated LED company, has announced the packaging-free 'White Chip' to demonstrate its new achievement in LED technology.

The new White Chip LED will make its debut at "Light + Building Frankfurt 2014," which is taking place until April 4th.

It is being demonstrated in various LED lamps, including the 50-watt halogen equivalent GU10 LED spot lamp, point-light candle lamp, and omni-directional LED tube.

Lextar's new White Chip technology involves substrate-free flip chip and phosphor molding process, and can be fabricated by current SMT equipment.  These features can simplify the manufacturing process significantly.

The firm's device is a chip scale die without packaging process, featuring high lumen densities, high lumen output, wide beam angle, and can be packaged closer therefore simplify optical lens design.

Lextar's White Chip can be applied to lighting products especially small sized lamps such as spot or candle lamps.  It can also be applied to backlighting, helping reduce the thickness of direct-lit backlight modules.

When used in GU10 spot lamp, this White Chip can achieve high lumen output and high lumen intensity, reaching up to 2500cd at a 25 degree beam angle; with a CRI 90 performance, making it a replacement for a 50 Watt halogen lamp.

The White Chip also gives its point-light candle lamp identically glowing effects to the starlight indoors.

Moreover, the light tube equipped with White Chip and COG (Chip on Glass) technology, on the other hand, allows 3600 illumination reaching an efficiency of 200 lumens per Watt.

"Since LED companies have been eager to attempt simplified manufacturing process at reduced costs in these few years, flip chip and several packaging-free LED products are getting more popular," says Reg Tsai, Director of Technology R&D Division of Lextar.

Thanks to its vertical integration, Lextar provides products and services through different stages from upstream chip to finished lighting products.

The company expects to move this newly launched White Chip into market during Q2 this year.

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.
