VTT And Lumichip Invest In LED Firm LightTherm

The firms will unite to simplify and develop more cost-effective methods in LED lamp manufacture
VTT Ventures and Lumichip are jointly investing in Finnish LED technology company LightTherm.

LightTherm uses its innovative materials and heat management solutions to introduce novel design and manufacturing capabilities for LEDs.

LightTherm's electro-thermo-mechanical technologies provide higher light output, leaner sizing and lighter weight in its products for the LED replacement lamp and luminaire industry.

The estimated global market for LED lamps is over US$20 billion, with more than 1 billion units due for manufacture in 2013. LED technology still faces some challenges, particularly where high light output is required from small compact light units.

The major difficulty with LEDs is the heat sensitivity of used components and materials. Overheating can shorten the lifespan and efficiency of the LED, while light output falls below product optimal specification as temperatures rise.

VTT Technical Research Centre of Finland produces high-level technology solutions and innovation services for its customers. VTT Ventures Ltd supports companies exploiting new technology, from business plan through to funding.

LightTherm Ltd is VTT’s new spin-off company, whose innovative LED interconnection solution can yield better thermal characteristics and cooler semiconductor junction temperatures. This capacity for better thermal efficiency management will have a major impact on the lifetime of LEDs. Combined with new materials for lamp body production, substantial cost savings can be achieved through reduced materials, manufacturing simplicity and total production automation.

“The high thermal management efficiency of this technology enables significantly higher light output – for example from replacement spots – than is currently available anywhere in the LED market," says Juha Rantala, Chairman of Lumichip Ltd.

“LightTherm materials, device construction and manufacturing processes give flexibility in design, and will enable the manufacture of entirely new lighting applications for both consumer and industrial luminaires. We believe this will change completely the way in which LED products are manufactured in the future," adds Rantala.

LightTherm's technologies are based on years of development, characterisation and lifetime tests carried out at VTT Technology Research Centre of Finland, which provides high-end technology solutions and innovation services. “We are pleased to co-operate with a partner such as Lumichip to take this very innovative and promising technology to the industrialisation and commercialisation phase," says Antti Sinisalo, CEO of VTT Ventures Ltd.

LightTherm's founding team consists of Petri Nyman, Ville Moilanen and Kimmo Jokelainen. CEO and co-founder Petri Nyman has extensive experience in start-ups, as well as in the management of growth companies. Co-founders Ville Moilanen and Kimmo Jokelainen have a research background with VTT and have been instrumental in developing the core innovations behind this new technology.

VTT Technical Research Centre of Finland is the largest multi-technological applied research organisation in Northern Europe. VTT provides high-end technology solutions and innovation services. The mission of VTT Ventures Ltd is to extract value from VTT technology by developing the international growth potential of VTT-based high-tech companies.

VTT Ventures, together with its public and private innovation partners, provides entrepreneurs with professional business development support to facilitate the spin-off process, from business planning through to funding. VTT Ventures co-invests in its spin-offs with private investors. The goal of VTT Ventures is to stimulate innovation in Finland and to receive a return on its pre-seed and seed capital investments.

Lumichip is a provider of customised LED lighting components. Lumichip designs, manufactures and markets proprietary LED components and specialised COB devices, and offers custom designs and manufacturing services for high power LED light engines, special luminaires and multi-wavelength modules for lighting and industrial applications. The development and manufacturing operations in Asia and Europe provide customisation and service support for its worldwide client base.

LightTherm is an ODM designer and manufacturer of thermally highly efficient LED structures, components and designs. LightTherm’s patent pending technologies enable the use of new materials in LED luminaires and LED engine components, resulting in greater design and manufacturing freedom and high quality light and lumen output from all its designs. LightTherm operates with customers and partners globally.

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.
