Samuli Siitonen, CTO,Nanocomp: “Flexible and Ultra Thin Light Guide Film Technologies for Displays and General Lighting”
Bio: Dr. Samuli Siitonen is Chief Technology Officer at Nanocomp Oy Ltd. Mr. Siitonen joined the Nanocomp team in 2001. He received his Ph.D. in diffractive optics for light guide applications at the University of Eastern Finland. He applies wide-ranging knowledge gained from experimental research and industry-related cooperation in multiple areas of manufacturing technology in field of nano- and micro-optics. He is responsible for Nanocomp’s research, technology, and product development activities.
Abtract: Lower energy consumption, longer lifetime, smaller size and greater reliability of lighting and display applications are features which can be implemented by using modern LED and nano- and micro-optics. Typically, if illumination is created by LEDs, a powerful light in-coupling and out-coupling from light guide surfaces are necessary in lighting modification. Micro structured features enable power-efficiency and cost-efficiency solutions for display illumination. Nanocomp’s technology offers a wide range of customized design, fabrication and replication solutions in the field of uniform light diffusion. Nanocomp has developed an ultra thin light guide film for small and medium-sized LCD backlights and reflective displays by excellent color and clarity with invisible micro-structures. While being ultra-thin, the LGF offers superior efficiency and excellent uniformity. The exceptional thinness and efficiency are enabled by Nanocomp´s the special double-sided micro-imprinting technology used for the light out-coupling. A full mass production capability of roll-to-roll (R2R) ultraviolet (UV) embossing, provides the entire supply chain from design to production of polymer film type light guide films. UV-R2R embossing process is a highly accurate and cost effective way to replicate large quantities of thin light guide films.
Dr. Veli Heikkinen, R&D Director, Flexbright: “High-Capacity Manufacturing of Customised LED Foils for Large-Area Display and Architectural Lighting Applications”
Bio: Dr. Veli Heikkinen has worked in the R&D of photonic modules and optical instrumentation for 30 years. Since 2006, he has developed hardware for LED-based lighting applications.

Abstract: Flexbright is a contract manufacturer and technology partner specialized in the roll-to-roll (R2R) assembly of LED lighting hardware. Our custom-designed products use flexible, transparent and low-weight plastic substrates together with components in SMD, CSP (chip scale package) or chip form. LED foils can include integrated sensors (ambient light, humidity, …), printed solar cells, batteries and wireless communications enabling Internet-of-Things platform and Smart Lighting features: dimming, occupancy sensing, human centric lighting, spectral tuning, visible light communications. Currently the main applications fields are architectural lighting and RGB displays for automotive use.
Markku Laatikainen, CEO, Valtavalo: “Why should you choose a LED tube light instead of an integrated LED fixture”
Bio: Mr. Markku Laatikainen is the CEO and co-founder of Valtavalo Ltd., a Finnish Company, specialised in developing, manufacturing and supplying energy-efficient and environmentally friendly LED lighting solutions. He has previously worked in the fields of ICT and education, i.a. as an IT Manager and a Managing Director. By leading Valtavalo since 2008, Laatikainen has put a great effort in opening and establishing LED tube market in Finland.
Abstract: There is no simple and all around answer to the question since even lighting market analysts have conflicting views on the future of the LED tube and integrated LED technologies. In my presentation I will consider the subject from the cost perspective, encompassing the initial investment and lifecycle costs, and from the perspective of practical use. If big light corporations do not consider LED tubes a profitable product segment, does it mean that there are no markets for them, or that the products are a poor choice for the end customer, compared to the integrated LED lights that the big corporations wish to promote? I strongly believe that there is a reason to dig more deep into this matter.
