costs in the conventional lighting sector over the coming years in an effort to retain profitability. To this end, it will be raising charges in the second half of 2014 from EUR 100 million to approximately EUR 170 million.
VI Systems gets US patent for 40G VCSEL technology
Patent also applies to visible and infrared LEDs
VI Systems GmbH, a developer and producer of optical devices for data transmission, has received a US patent covering the material composition of optoelectronic devices including VI Systems’ 40 Gbit/s vertical cavity surface emitting laser (VCSEL).
The patent ‘Optoelectronic Device with a Wide Bandgap and Method of Making Same’, protects the company’s proprietary concept of ultra high- speed vertical VCSELs. The invention relates to semiconductor light emitting devices for visible and infra-red spectral ranges, and can therefore also be applied to LEDs targeting the bright red, orange, yellow, or green spectral ranges.
VI Systems’ offers engineering samples of its 40 Gbit/s VCSEL at 850nm wavelength as bare die chips or as fibre coupled test modules.
Philips accelerates lighting
business changes Intensified focus on LED systems
Philips is accelerating the drive to LEDs, the group said today in its second quarter and semi-annual results 2014. The move follows the company’s announcement a few weeks ago to combine its LED and automotive lighting businesses in a stand-alone company.
The firm’s LED-based sales grew 43 percent in Q2 and now represent 36 percent of total Lighting sales, compared to 25 percent in Q2 2013. There was a 13 percent decline in conventional lighting sales in the quarter.
Along with the increased focus on LED, Philips will pull forward plans to scale down production and cut

“In Lighting, we are intensifying our focus on connected LED lighting systems and services, LED luminaires, and LED lamps for the professional and consumer markets,” said Frans van Houten, CEO. “Our decision to combine the Lumileds and Automotive lighting businesses into a stand-alone company within Philips will allow it to extend its leading portfolio of digital lighting components and achieve robust growth, serving even more customers in the industry, as well as Philips Lighting.”
Nichia to commercialise laser diodes for Automotive Head- Up Displays
New blue and green laser diodes to replace LEDs
Nichia Corporation, headquartered in Tokushima, in Japan, plans to commercialise blue and green semiconductor laser diode models specifically designed for automotive Head-Up Display (HUD) systems.
LEDs are currently the most common light sources for automotive HUD systems. By replacing LEDs with semiconductor laser diodes, Nichia says it will be possible to achieve a larger head-up display field of view, lower energy consumption, higher contrast, and an extended range of reproducible colours
Nichia plans to start shipping test samples from October 2014 and mass production from October 2015.
