Philips Lumileds Newest Emitter Doubles Lumen Density and Center Beam Candle Power
LIGHTimes News Staff
February 25, 2014...Philips Lumileds has introduced the Luxeon MZ, a new high power emitter. The
company claims it enables tighter beam angles with higher lumen density at a
lower cost than was previously possible. The Luxeon MZ emitter boasts excellent
optical control in a 600-1000 lm package. The Luxeon MZ can power outdoor,
industrial and area lamps as well as spotlights and downlights. The company
notes that designers can qualify their luminaires faster and bring them to
market sooner because of its design compatibility with the Luxeon M emitter.
“With the Luxeon MZ in combination with Luxeon M, designers can
create two solutions with one optic and one PCB, thereby lowering overall
costs. Our customers are already designing platforms with LUXEON M and Luxeon
MZ to create multiple SKUs using less engineering resources,”
explained senior vice president, Emmanuel Dieppedalle.
Philips Lumileds says that in an MR16, the Luxeon MZ can deliver 50,000
candela center beam candle power (CBCP). Whereas, encapsulated emitters only
achieve half that beam intensity with same sized optics. So luminaires such as
flood lamps that require CBCP and formerly required large optics now can
deliver the necessary CBCP with smaller optics and off-the-shelf drivers.
The Luxeon MZ features an undimmed design for smaller beam angles and a
small light emitting surface of 4.2 mm in diameter. It has a forward voltage of
11.2V. The company is offering the emitter family across the full range of CCT
and CRI (70, 80, 90) and CCT (2700-6500K) options.
Philips Lumileds Luxeon Lime LEDs Break 200 lm/W Barrier
LIGHTimes News Staff
February 18, 2014...Philips Lumileds has released its new Luxeon Rebel ES Lime, the company's
latest edition to its Luxeon color portfolio. The company boasts that the Luxeon
Rebel ES Lime has achieved greater than 200 lm/W efficacy. It must be noted
that the company's most efficient green LED is 109 lumens per watt. The
company's Luxeon Rebel ES lime LED, which is actually a yellowish green is
employed in the Philips' hue bulb in which it is combined with the Luxeon Rebel
Red-Orange, and the Luxeon Rebel Royal Blue LEDs to create over 16 million
color options controlled through an iOS (Apple's Opporating System) device.
Philips hue can use color tunable Light Recipes to help set the atmosphere and
mood in the home, office, retail, classroom and hospital environments.
“This really represents a new frontier in lighting, because LUXEON
Rebel ES Lime emitters can be combined with other Rebel color and white
emitters to achieve higher CRI and R9 combinations than any previous generation
emitters or arrays,” said Rahul Bammi, VP of Product Management.
Lime is the highest efficacy LUXEON LED manufactured to date. Therefore it
enables highly efficient color mixing by providing a convenient above-blackbody
color point with optimal standalone efficiency of 200 lm/W at 350 mA and 85°C.
The spectral output of Lime is closely aligned with the wavelength that human
eye cones are most sensitive to, 555 nm.
“We are finding that all our customers are very interested in Lime
due to the outstanding efficiency and flux it brings to every lighting
application,” said Bammi.
In addition to LUXEON Rebel ES, Philips says its Lime technology is offered
in the LUXEON Z format, that measures an unadomed, 2.2 mm2 LED that is 75%
smaller than most high power LEDs. In spotlight and downlight applications, the
LUXEON Z enables tighter packing density and better color mixing control. The
LUXEON Z Lime can be combined with Red and Blue LEDs to achieve a broad
spectrum of saturated colors or tunable white light with high efficacy can be
achieved from 1800-6500K along the blackbody curve.
Notably, because Lime is closer to the blackbody curve than green LEDs, much
less inefficient red is needed to make white light with Lime instead of green,
especially at warmer color temperatures. For instance, color tuning of
2250-2950K can be achieved with an R9>90, CRI>90 and efficacy of 90 lm/W
using LUXEON Z combinations. When using a similar combination of Red, Green and
Blue LEDs to create 3000K white light, the CRI is close to 20.
According to Dave Cosenza, product manager, at Philips Lumileds,
"Lime is a Phosphor Converted Color based on the same technology that is used to create White LEDs. The combination of Lumileds industry leading Royal Blue ‘Pump’ with Lumiramic phosphor technology enables LUXEON Lime to create saturated color at wavelengths which cannot be efficiently made today by semiconductors alone. Because Lime’s color is actually midway between Green and Amber, the spectral power distribution is closely aligned with the wavelengths which our human eyes perceive as most bright."
Sharp Introduces Color Temperature Tunable Mini Tiger Zengata LED
LIGHTimes News Staff
February 18, 2014...The apply named Mini Tiger Zengata LED uses a combination of warm white and cool white LED di together. The warm and cool white LED di form stripes (hence the appropriate name Tiger). The ability to create varying degrees of cold or warm white light are required to create a particular atmosphere, promote a sense of well-being or even boost productivity at work. Certain surface lighting and light strips already have adjustable color temperature solutions using some combination of red, blue, and green or cyan magenta, yellow, amber to create the desired color temperature. Spotlights and downlights are especially difficult to do because the efficiency required usually precludes colored LEDs and spotlights often preclude multiple LED light sources. Sharp claims that its Tiger Zenigata LEDs are the first single point light source with variable color temperature on a substrate.
The tuneable white TigerZENI LED works combining warm white and cool white multi-chip LEDs within a single COB solution, creating a tiger-stripe appearance. A two-channel driver can be used to drive the two colors independently, allowing smooth tuning from warm white (2,700 K) to cool white (5,700 K) by varying their relative drive current. Sharp says that the Tiger Zengata can be tuned through its entire color temperature range while maintaining a lumen output of 2,000 lm. It is possible to maintain the luminous flux whilst tuning the color temperature by choosing appropriate drive currents.
New Cree CXA High-Density LED Arrays Have Unprecedented Lumen Density
LIGHTimes News Staff
February 12, 2014...Durham North Carolina-based Cree Inc., has launched three new LED arrays
with double the light output of existing CXA LED arrays without increasing the
size. According to Cree, the XLamp® CXA2590, CXA1850 and CXA1310 High-Density
LED Arrays have an unprecedented increase in lumen density. Cree asserts that
this new level of lumen density creates new levels of light intensity, enables
the complete replacement of ceramic metal halide (CMH) light sources, expands
the abilities of LED spotlights, and makes possible applications that could not
be addressed by previous LED technologies.
“The beauty of these new high-density LED arrays from Cree is that
they are helping us bring products to the market that currently don’t
exist,” said Mike Wang, vice president, lighting engineering, Edison
Price Lighting, Inc. “Never before have we been able to harness such
a large amount of light in such a small package, which can help us improve our
lighting designs and address a number of applications that we previously could
Cree says that the CXA2590 Array's emission of more than 15,500 lumens from
a 19 mm light source, makes possible luminaires with the same center beam
candlepower (CBCP) and light quality of a 150-watt CMH light source at lower
power, with longer lifetime and better control. Delivering more than 9,000
lumens from a 12 mm light source, the CXA1850 LED Array provides the same CBCP
and light quality as 70-watt CMH while using half the power. Cree notes that
the CXA1310 LED Array delivers more than 2,000 lumens in a 6 mm light source.
According to Cree, this gives lighting manufacturers the opportunity to design
smaller, more efficient track lights, reduce the size of halogen replacements
by half and deliver twice the CBCP of CMH at 30 percent less power.
“Having access to such intense light sources without having to
account for lots of variation in size is a tremendous benefit to our product
design process,” said Seok-Ki Park, CEO, Hwang-Duck Engineering Co.,
LTD. “We have the flexibility to increase our design options while
protecting our investment in ongoing product development.”
Like all CXA LED Arrays, the new arrays are characterized and binned at
85°C, available in ANSI White and EasyWhite® color temperatures (2700K –
6500K), and with CRI options of 70, 80 and 95. Samples of all three new
high-density LED arrays are available now and production quantities are
available with standard lead times.
Samsung Announces More Efficient Chip-on-Board LEDs
LIGHTimes News Staff
January 29, 2014...Samsung Electronics Co., Ltd. based in Seoul, South Korea, announced some new very efficient chip-on-board (COB) LED packages. Samsung’s LC013B, LC026B and LC040B feature a compact light emitting surface (LES) with high light output that is designed for use in high performance LED products. The improved COB type LC series offers a light efficacy of 130lm/W at 3000K CCT (Correlated Color Temperature) and 143lm/W at 5000K with a CRI (Color Rendering Index) over 80. This represents a significant improvement from 120lm/W at 3000K and 129lm/W at 5000K respectively, the light efficacy levels that Samsung has been offering with its LC series since April.
The company reportedly made the efficiency improvements thanks to enhancements in the company's phosphor technology and improvement in its chip fabrication techniques. Samsung’s LC series is also Zhaga-compliant, and therefore convenient in assembling most LED lighting products. This latest LC series is expected to be applied in a wide range of interior LED lighting applications including downlights, spotlights and directional retrofits such as MR/PAR lamps.
The LC Series leverages chromaticity control standard 3-step MacAdam ellipses for high color uniformity and light quality. The packages also boast low thermal resistance and superior heat dissipation. They have successfully completed LM-80 testing, a widely observed test method for lumen maintenance developed by the Illuminating Engineering Society.
The Samsung LC series has added a 3500K version to the 2700K, 3000K, 4000K, and 5000K versions that have been available. Samsung’s latest LC series comes in 13W, 26W and 40W versions depending on the LED product with which the packages are used. The LC013B, LC026B and LC040B with improved light efficacy will be available in the market beginning next month and Samsung says that they will be updated to have a CRI above 90 in the first half of the year.
By 2017, About 50% of Lighting Shipments Will Include Super High Powered LEDs, According to Strategies Unlimited
LIGHTimes News Staff
January 29, 2014...According to Strategies Unlimited (SU), revenues for LEDs in lighting
applications are expected to rise at a compound annual growth rate of 30%. The
company says that by 2017, the revenues will reach a total of $13 billion for
LEDs in lighting applications, which includes both replacement lamps and
luminaires. The chart below shows the market growth for LEDs in Lighting by
major region compared to the Rest of the World (ROW).
The company reports that high brightness (HB)-LEDs saw a "precipitous fall in
prices" over the last several years, which in turn helped reduce the price of
LED lamps and luminaires. However, SU says that this decrease in prices has
been slowing down in recently. According to Philip Smallwood, Research
Director of LEDs and Lighting at Strategies Unlimited, “ASPs of
packaged LEDs are declining at a slower rate than previous years, as super high
power LEDs increase in the market. While prices for all LEDs are decreasing,
the increased penetration of these SHP LEDs (which have a higher price) is
raising the overall ASP for all packaged LEDs.” The graph below
represents the growing market share of Super High Power (>5W) LED packages
in the coming years.
SU says that efficacy improvements are also continuing in the market, with
the average efficacy of commercially available LEDs for lighting applications
increasing to greater than 100 lumens per Watt for 1W packages, and multichip
arrays have reached efficacy as high as 200 lumens per Watt. SU contends that
LED efficacy is no longer the "gating factor" for LED applications, cost is.
The company points out that lighting applications have seen a variety of
different packages used over the last year, including arrays, high CRI, tighter
color bins, directional, multi-directional and high voltage LEDs.
Strategies Unlimited predicts that the growth rate for LED package units and
revenues will both be in double digits for the forecast period. According to
Smallwood, “While growth in the market can be attributed to
improvements in the technology and decreases in its price, the largest
penetration increases seem to be coming from government mandates that either
restrict incumbent lighting technologies or push the usage of LEDs.”
SU notes that one of the largest impacts of these regulations will be seen in
2014 in the United States, as the implementation of the Energy and Independence
Security Act of 2007 is phasing out 60 and 40W incandescent A-lamps.
LED Lighting Market to Grow Over 12-Fold to $25 Billion in 2023, According to Lux Research
SSL Design News Staff
January 28, 2014...The market for light-emitting diode (LED) luminaires, or optimized permanent
light fixtures, will grow more than 12-fold over the next decade, according to
Lux Research. It will grow from $2 billion today to $25 billion in 2023, a
compound annual growth rate (CAGR) of 25%. The growth will be driven by
superior features and falling costs. Lux Research used historical trends as
well as projected average price reductions to build a model that calculates the
adoption rate of LEDs within each end market application -- office, industrial
and street lighting. They found that recessed modular will emerge the largest
LED luminaire market, growing from $1.5 billion in 2013 to $14.5 billion in
2023 by replacing incumbents such as fluorescent.
"As LED packages rapidly fall in cost and improve in efficiency, the
cost structure of LED luminaires will shift, and present opportunities in other
components such as secondary optics and drivers," said Christopher Hwang,
Lux Research associate. "This trend, in turn, influences the rate of
adoption of emerging technologies, such as alternating current (AC) LEDs and
high-CRI LEDs in recessed modular, high-bay and roadway luminaires," he
Lux Research analysts examined the LED industry to identify the largest
opportunities within the luminaire market for investors, technology developers
and component suppliers. Among their findings: Lux Research predicts that LED
package costs will fall over 80% to less than $4/klm on improved efficiency,
increased manufacturing yields and utilization. As a result, the bill of
materials (BOM) of a standard 3,500 lumen recessed modular luminaire will fall
35%, from $85 in 2013 to $55 in 2023.
The company predicts that AC LED-based luminaires will become cost
competitive by 2018, but will provide a technology advantage only in low-power
applications, such as recessed modular luminaires. However, high-CRI luminaires
will remain a niche product, with a 9% cost premium by 2023, finding adoption
in high-occupancy applications.
Lux Research also forecasts that the LED package market will be dwarfed by
opportunities in optics and drivers. The secondary optics market will be the
single biggest growth opportunity in components, growing to $6.9 billion in
2023, while the drivers market will reach $4.9 billion.
SemiLEDs C35 LEDs Power Luminaires in Twenty First Light's Hotel Alpha Project
SSL Design News Staff
January 8, 2014...The tourist hotel complex (THC) Alpha in Moscow recently received a
new facade wall-wash from Twenty First Light ltd, a Russian manufacturer of LED
luminaire solutions. The luminaires are powered by SemiLEDs Corporation, C35
color and warm white LEDs. Twenty First Light developed three types of
saturated purple and warm white spotlights for the project with substantial
product support from SemiLEDs. The luminaires achieve what Twenty First Light
describes as both a powerful visual impact and high reliability for the
distinctive lighting scheme.
"THC Alpha is a high profile landmark in Moscow, and as such, this was a
high-exposure project for Twenty First Light that demanded a solution which
would start out visually appealing, and then stay that way over the life of the
installation," commented Sergey Stakharny, director of Twenty First Light.
"It was very important to us that the LED manufacturer both understood what
we were trying to achieve, and would provide flexible support that minimized
our engineering challenge while streamlining the project and maximized the
reliability of the installed luminaires. SemiLEDs was able to meet those needs,
contributing to the success of this program."
Twenty First Light developing three distinct types of luminaires for the
project including: 40W saturated purple spotlights for the individual balconies
on the building's side, as well as narrow-beam 100W purple, and 70W warm white
spotlights illuminating the building facade for a color-fade effect from bottom
to top. In addition, a series of prototype 150W RGB color-changing spotlights,
also based on SemiLEDs C35 LEDs, were developed to allow on-site testing of
different hue and saturation effects. With the final selection being a
saturated purple, Twenty First Light engineering a static combination of blue
and red LEDs matching the specified and tested shade to optimize the
performance and value of the light combination. The LEDs were surface mounted
on a single aluminum array plate, and supplemented by secondary optics for a
10-degree beam angle. The 100W purple and 70W warm-white spotlights
respectively replaced 400W and 250W high pressure sodium lamps. This resulted
in over 70% energy savings.
"We were very pleased to support Twenty First Light in the development
of these customized luminaires constructed around SemiLEDs C35 family of
LEDs," commented Dr. Ilkan Cokgor, Executive VP of Sales and Marketing for
SemiLEDs. "One big promise of LEDs is to enable the kind of design
flexibility that Twenty First Light devised, allowing the end-specifier to see
a dynamic test luminaire for color selection, and then translating that into a
cost-optimized, and highly reliable production solution set. That flexibility
demands a wide product offering, robust technology, and a manufacturer that has
the ability to interact with the luminaire designers with individualized
support. It's what distinguishes SemiLEDs as both a technology and solutions
