NEWS & TECHNOLOGY OPTOELECTRONICS EETimes Europe: Highly inte- grated – does this mean that you integrate the driver circuitry onto the led chip? M. zeiler: Yes, for instance. this is one option. also the connecting technology is designed to be as slim as possible. We always have solutions that are different. In ad- dition, we have many promising contacts with large oeMs which are interested in our technology. If you look at the details, in the high-volume retrofit market it even makes sense to run a production in europe – if you have a high degree of automation. EETimes Europe: Where are your manufacturing locations? M. zeiler: everything but the chips are produced in St. Petersburg. In dortmund we have R&d and a pilot production. our high volume Slim, cost effective processes and leading solid-state IP are the two main pillars of Optogan’s production is here in landshut technology strategy. where we can use existing infra- structure (from lFoundry), clean rooms etc. We can rent the ing is a “dead spot” on our R&d map. infrastructure with an option for further enlargement, ideal for mass production.

In these concepts, complete solutions with tiered lighting business, yes. this could happen in a time frame of drivers and heat sinks play a major role. In addition, we see a three to five years while it took some 25 years for the CFL to trend to ever-higher integration. the customers are increasingly gain significant market share in conventional lighting. But one looking for reduced component count through higher integra- should not expect a complete changeover. In certain market tion. segments such as automotive or laptop display backlighting, leds conquered the markets very quickly. In general lighting, EETimes Europe: Is the ability to control dimming a factor in the this won’t happen at the same speed. the established lighting market acceptance? companies do not move that fast. this is a clash of the cultures – conventional lighting and the fast-moving semiconductor M. zeiler: Yes – for example in the markets for home lighting industry. where dimming is a popular feature for retrofit lamps. We also see an increasing interest for dimming in industrial applications: EETimes Europe: Which market segments do you expect to it enables users to dim down the lighting in storage halls as long grow the fastest?
