New phosphors with up to 50% improved energy efficiency

Through earlier announced partner agreements with developers and producers of
phosphors and intelligent materials, LightLab Sweden AB has, during the first
half of 2014, got access to a new generation of phosphors offering significantly
improved energy efficiency.

“We have measured improvements between 20% and 50% for red, green and blue
phosphors, compared to our 2013 recipes, and we are currently in the process of
introducing these improved materials into our reference design light powder”,
says Jonas Tirén, VP R&D. “There is also significant potential for further
phosphor improvements, something that LightLab and our partners will continue to
work on during the second half of this year”, Jonas Tirén continues.

Before the resulting improvement on integrated lamp level can be realized,
measured and presented, the new phosphors require adaptation of the currently
used light powder coating process. This is currently being done with our
partners while simultaneously developing further improved phosphor materials.

“We continue to improve the performance of the critical material system with the
goal to achieve 60lm/w during 2014” says Jan-Erik Lennefalk, CEO LightLab.
