Top 20 LEDs Magazine news stories of 2012:
A light guide provides omnidirectional light distribution
in 3M's new LED-based lamp that is decidedly different from the typical SSL
approach to the retrofit application.
Strategies Unlimited’s analysts believe that the LED
lighting market is growing nicely, though they expect lower LED prices to keep
a lid on LED-component growth in the foreseeable future. LAURA PETERS and MAURY
WRIGHT report from the Strategies in Light conference.
The MR16 LED lamps face certain transformer and dimmer
compatibility issues. Still, major lamp manufacturers have introduced 50W
halogen equivalents in 8-10W LED lamps and feel the lighting market is ready to
make the switch, reports LAURA PETERS.
The worldwide LED market grew 9.8% to $12.5 billion in
2011, with 44% growth in the lighting sector, according to Strategies
Unlimited, who revealed the top-ten LED suppliers for the year. However, the
outlook remains roughly flat for the next 5 years, peaking in 2013.
Relative to visible LEDs, UV LEDs are a quiet market at
only $30 million, yet recent breakthroughs in radiant power and intensity have
enabled the displacement of mercury-vapor lamps in applications including UV
curing and counterfeit detection, reports LAURA PETERS.
Lightfair will see a number of companies introduce SSL
retrofit lamps that are equivalent of 100W incandescent bulbs and GE and
Philips Lighting announced such products before the exhibits opened.
A recently-released report from McKinsey & Company on
the worldwide lighting industry indicates sizable growth for LED-based
lighting, says LAURA PETERS.
MR16 sockets present a significant retrofit-lamp
opportunity for LEDs, explains KAMAL NAJMI, but installed transformers
complicate the design of a drop-in SSL replacement.
Silicon Valley start-up Soraa is manufacturing LEDs using
a unique GaN-on-GaN process, and has used these to build high-performance MR16
lamps that are its first products.
