Everlight Adds High-voltage Packaged LEDs to Portfolio
LIGHTimes News Staff
July 29, 2014...Everlight Electronics has introduced the XI3030HV family of packaged LEDs.
The XI3030HV family serves as a high-voltage addition to the company's standard
XI3030 line. The company packages both the XI3030HV and the XI3030 line in a
3×3-mm plastic packages. The product family ranges from mid- and high-power
segments to some models that operate in excess of 1W. The company asserts that
the new high-voltage LEDs can simplify the design of the LED driver electronics
and reduce solid-state lighting (SSL) system costs.
High-voltage LEDs combine multiple emitters/junctions in series or several
parallel strings of a number of LEDs in series. Some packaged LEDs connect
separate chips that are packaged together with bond wires. Others make the
electrical connection to multiple emitters on one monolithic chip that forms
separate emitters at the end of the LED manufacturing process.
The higher-voltage input can provide several advantages. The lower
difference in line-to-LED voltage reduces the component count in drivers and
can increase energy efficiency. Everlight says that its XI high-voltage LEDs
deliver efficacy of 120 lm/W at 3000K CCT, very good but not top-level
performance at the warm end of the color spectrum. The LEDs have a minimum 80
CRI and a 115-lm maximum flux output.
So far Everlight has just 3000 hours of test data on the brand new products.
However, the company said LM-80 testing is in progress. Everlight has begun an
initiative that follows a recent trend in LEDs, producing particular packaged
LEDs for specific applications in terms of voltage input levels, package
features, and optical performance. Everlight calls the initiative "The Right
LED for the Right Application." The company said it plans to provide custom
versions of the high-voltage arrays at any voltage that customers require.

July 9, 2014...Philips Lumileds launched its proprietary CrispWhite Technology, which the
company says makes colors appear saturated, and whites appear vivid and bright.
Luxeon CoB arrays with CrispWhite Technology are designed to create more
inviting and attractive displays with retail downlights and spotlights.
Lumileds points out that proper lighting is essential for the perception and
evaluation of goods and is also an important component of branding, promoting
and presenting merchandise and creating an inviting space for shoppers.
According to Lumileds, the company's CrispWhite Technology, acts like daylight,
giving all colors, including the white, the best saturation.
“CrispWhite delivers the light quality that retailers have been
seeking for some time,” said Eric Senders, product line director,
Philips Lumileds. “Shop owners have told us that CDM sources do a
fine job of rendering warm colors but they would like to save energy and take
advantage of the longer lifetime of LEDs.”
The new CrispWhite LEDs are said to maintain high CRI and bring out the
white color in merchandise. According to the company, the CrispWhite LEDs like
CDM lamps have a second peak in the blue spectrum for optimal illumination of
retail displays. Luxeon CoB arrays with CrispWhite Technology come in lumen
packages ranging from 800 lumens for MR16 and PAR lamps, up to 7000 lumens to
replace 70W and 100W ceramic discharge metal halide solutions.

LIGHTimes News Staff
July 1, 2014...LED chip suppliers Epistar Corp and Formosa Epitaxy Inc reported that the
companies plan to merge through a share-swap later this year, according to
Times. The companies expect the merger to improve their operating
efficiency and competitiveness in the global market.
Epistar, Taiwan's biggest LED chipmaker, indicated that the company plans to
issue more than 170 million common shares in exchange for 586.16 million ForEpi
shares based on a share-swap ratio of 3.448. The share swap is scheduled to
take effect on Dec. 30, according to the companies. Once the transaction is
completed, ForEpi will become a wholly owned subsidiary of Epistar. The merged
entity will hold more than NT$11 billion (US$368 million) in paid-in capital
and have a total of 6,700 employees.
In a filing with the Taiwan Stock Exchange the companies noted that the
merger would expand Epistar's business scale, integrate Epistar and
ForEpi’s resources, and lower their management costs. Based on
Epistar’s closing share price of NT$74 Monday and ForEpi’s
NT$18.25, Epistar is offering to purchase the ForEpi shares at a price that is
17.6 percent higher than Monday's closing price. The deal is still subject to
approval by the two companies’ shareholders at their respective meetings
on Sept. 1.
According to market research firm TrendForce Corp., Epistar has 385 metal
organic chemical vapor deposition (MOCVD) machines for producing LED chips.
Along with ForEpi’s 103 MOCVD units, Epistar will reportedly have nearly
500 MOCVD systems by the end of the year.
Streetlights to Power Demand for High-Power LED Shipments Through 2017, according to NPD DisplaySearch
SSL Design News Staff
June 26, 2014...Shipments of high-power LED chips used in streetlights, direct
backlit LCD displays, spotlights, and other applications that
require higher brightness are expected to grow at a compound annual
growth rate (CAGR) of 13% between 2014 and 2017, According to NPD
Display Search. The NPD DisplaySearch forecasts that
demand for high-power LEDs will increase from
18.5 billion in 2014 to 27 billion in 2017. Streetlights
are projected to have a 28% share of total high-power LED shipments
in 2014. Streetlights are closely followed by TV backlights and
spotlights with 27% each; however, streetlights are expected to
dominate the high-power LED market in 2017 (41%), followed by
spotlights (21%) and TV backlights (15%).
“The LED lighting source makes up a small part of the total
material costs, and that is driving growth in high-power LED
shipments,” said to Steven Sher, LED research analyst at NPD
DisplaySearch. “While prices for high-power LEDs are higher than
prices for typical LEDs, these lighting systems are still
affordable, and demand for energy-efficient, brighter lighting
continues to grow, as energy costs rise.”
NPD DisplaySearch notes that high power LEDs now use ceramic
substrates instead of the polyphthalamide material formerly used in
the manufacturing process. to improve thermal conductivity. The
company also points out that glass lenses have replaced silicone
lenses to reduce humidity.
“Effectively managing the thermal issue is very important for
high-power LED applications, because it influences the reliability
of the technology,” according to Sher.
“High-power LED boasts excellent sell-through, and we expect to
see an increased penetration rate in the general lighting and
display application category this year,” Sher said. “Only
a few big LED component makers will continue to dominate the
market, however, including Philips Lumileds, Osram, and Cree.”

Cree Debuts XM-L2 with 38 Percent Performance Improvement Over XM-L
LIGHTimes News Staff
May 29, 2014...Cree, Inc. has introduced the new XLamp® XM-L2 EasyWhite® LED. The
multi-chip, packaged LED provides over 1,100 lumens from a 5mm x 5mm package.
The XM-L2 enables 38 percent more light output and efficacy in the same
footprint as the EasyWhite XM-L. The XM-L2 can serve as a drop-in upgrade to
the first-generation XM-L EasyWhite LED.
“The new XLamp® XM-L2 EasyWhite® LED offers greater optical
control and an immediate performance boost to our existing designs using the
XM-L EasyWhite LED,” said Tom Tang, Chairman, Tons Lightology Inc.
“Having a drop-in replacement eliminates the need to redesign
existing products, which lowers costs and helps speed our time to
Cree developed the XM-L2 to be a single component for compact lighting
designs. The XM-L2 EasyWhite LED reportedly emulates the appearance and matches
the color consistency of halogen lamps. The XM-L2 EasyWhite LED provides 4-step
and 2-step MacAdam ellipse bins for the best color consistency, which museum,
retail, residential, and hospitality applications require.
“We were the first to introduce an LED optimized for 50-watt
halogen performance with the XLamp® MT-G EasyWhite® LED. Now with the XM-L2
EasyWhite LED, Cree delivers the same amount of light with the best color
consistency in a package that’s 70 percent smaller, reducing the system
cost for LEDs in halogen replacement applications,” said Paul
Thieken, director of marketing, LED Components, Cree, Inc.
Cree characterizes the XM-L2 at 85°C, and it is available with forward
voltage configurations of 6V or 12V with 80 and 90 minimum CRI options and
color temperatures ranging from 5000K to 2700K. Cree points out that the XM-L2
EasyWhite LED is a “successor” to the XM-L EasyWhite LED.
Therefore, EnergyStar® qualification requires just 3,000 hours of LM-80 data,
which is half the testing time that the DOE usually needs.
XM-L2 Easy White takes advantage of same improvements that we used to improve the performance of the XLamp XP-E with the XLamp XP-E2. It'sa combination of all three basics: brighter chips, more efficient and reliable phosphors, and better packaging technology. The performance jump was large because we are continually researching brighter LED technology
and have made improvements ever since the EP- E2 announcement last year," Paul Scheidt said.
