Approximately 5 years after Luminus Phatlight were used in Samsung rear projectors, there is finally progress in front projectors
The big question: Round or Square Luminus LED designs?
The round design (pictured below) is Luminus latest technology. However Zombie's picture shows the older square LED's in the Panasonic.
Since green is 59% of the total lumens, replacing that color with a more efficient laser make sense.
Perhaps Luminus only developed the 30% more efficient round LEDs because they were losing market share to lasers.
Round LEDs Press Release
Frankfurt, Germany, Light + Building, April 19, 2012 ―Luminus Devices, Inc.,
announced today it will be releasing a family of round LEDs
that will accelerate the
adoption of solid-state technology by displacing conventional light sources in high
brightness lighting applications.
“Optical architectures of high power entertainment fixtures are frequently defined by a
circular aperture, so using a traditional square LED was like putting a square peg into a
round hole,” said Don McDaniel, Global Marketing Director for Entertainment Lighting
at Luminus. “Our new round LED increases system-level efficiency by as much as 30%,
enabling our customers to use a single LED to replace a 250W HID lamp.”
Other markets and applications that will benefit from Luminus’ round LED technology
include medical, machine vision, portable and retail spot lighting. “There are obvious
benefits to fiber coupled lighting systems,” explained Chuck DeMilo, Global Director of
Product Marketing, Lighting Business Group, at Luminus. “The fiber is round, the optic
is round, but the LED has always been square – it was an optical mismatch. This has
now been resolved with the round LED breakthrough that will enable us to replace the
300W Xenon lamp in an application like endoscopy.”
According to Luminus President and CEO Keith T.S. Ward, “We made a decision to
invest significantly in R&D and operational infrastructure to revolutionize LED lighting
– making the round LED concept a reality. The importance of this innovation can’t be
overstated, and our customers are extremely excited.”
