LED Engin Combines its LZ4-Plus Emitter with Gaggione’s Optics LIGHTimes News Staff
November 26, 2013...LED Engin, Inc., a maker of LEDs emitters based in San Jose, California USA,
has combined its LZ4-Plus emitters and Gaggione 8 to 45-degree zoom optics. LED
The LZ4-Plus are compact, 4-die RGBW emitters for wash lamps and follow spots.
The company claims that they can be driven to 1.5A per die to produce 30%
higher output than rival products. When matched with the Gaggione lenses, the
company asserts that designs of much smaller, lighter and more powerful
products are possible. The resulting entertainment luminaires will provide
bright, smooth, flat, progressive beams with soft yet clearly defined edges
over the full color spectrum,
According to LED Engin driving each die to 1.5A does not compromise the
reliability and operating life of the LEDs because the company’s
proprietary, multi-layer, thermally efficient substrate dissipates heat very
effectively. Each die is individually addressable for what the company says is
precise color control. In addition, the company says that the combination
reportedly enables in-source color mixing without the added complexity and cost
of attaching color filters to lamps. Based on LED Engin's proprietary LuxiGenTM
platform, the compact LZ4 emitters, capped with flat glass primary lenses, can
be used with secondary optics, including zoom lenses and imaging optics.
The die on the LZ4 emitters are mounted close together to create a very
small light source. This maximizes in-source mixing to produce uniform color
across the beam and it enables precisely controlled very narrow beam angles
down to 8 degrees or less. Gaggione claims that its total internal reflection
(TIR) zoom lens is one of the most efficient in the market, maximizing candelas
per lumen (cd/lm) in the beam. Gaggione also offers fixed, high precision TIR
lenses with narrow, medium, wide or elliptical beam angle profiles.
LZ4-Plus emitters are offered in single flux bins per color, reducing the
need to mix multiple bins. The products are being unveiled at LDI, the annual
entertainment lighting show held in Las Vegas, opening today.
LumaGlo Develops Bluetooth-Controlled Smart LED Lighting Strip SSL Design News
November 7, 2013...LumaGlo developed a Bluetooth-enabled, LED strip controller that connects
the a mobile phone wirelessly to the lights, granting the user total control
over their system. The company announced the launch of the product on www.kickstarter.com.
Users can turn on, off, dim, brighten, set timers, or even choose up to 16
million colors, even in real time by dragging their finger along the color
wheel. Each LED is individually addressable, producing dynamic patterns and
color combinations. It comes in a lengths of 1ft, 2ft and 5ft, all of which are
linkable up to 10ft.
LumaGlo asserts that existing LED light strip products on the market were
controlled with a generic remote that only allowed the user to choose a handful
of colors and simple patterns, and every LED had to be the same color. Strips
weren't linkable, and if you wanted a shorter length, it had to be cut,
throwing a part of the investment away.
"With today's technology, we couldn't figure out why those lights were
still being controlled like the dark ages," explained Randy Lathrop,
co-founder. "We knew there was a better way, and we began working to
develop a product that solved all of those problems."
LumaGlo also developed a modular/portable power option. "Users can plug
in a rechargeable battery and transform their installed applications to 'On the
Go' portable uses. LumaGlo can be used to increase visibility, to be seen in
clubs or at raves, decorate a skateboard or bike, or even use at events or
ceremonies," said Ward Ramsdell, co-founder. Other uses include
under-cabinet lighting, accent lighting, hallway illumination, brightening
retail space, and much more.
"What we're most excited about is that we've developed the first
lighting system that is truly universal. It's installable and wearable,"
said Jill Saucedo, Co-founder. "It can be used to decorate with light in
the residential setting, attract customers in commercial spaces or gain
visibility with the 'On the Go' portable options."
Intematix Announces 203 Lumens per Watt Remote Phosphor LED Lighting Module LIGHTimes News Staff
November 5, 2013...Intematix Corporation, a manufacturer of phosphor solutions based in
Fremont, California USA, and Philips Lumileds announced a remote phosphor-based
LED lighting module with a claimed 203 lumens per watt efficacy. Philips and
Intematix say that they believe that this module has the highest level of
efficacy among commercially available LED-based light sources.
"This result is a significant step along our innovation roadmap for
phosphor solutions," said Yi-Qun Li, Chief Technology Officer at
Intematix. "Remote phosphor architectures lower cost, increase efficacy and
improve light quality in many of the consumer, commercial, industrial and
outdoor area lighting applications commonly deploying LED technology
The LED lighting module from Philips uses a commercially available, 26mm
diameter dome shaped remote phosphor from Intematix that converts blue light to
on-the-black-body-line 6000K daylight spectrum and 70CRI with conversion
efficacy of 267 lumens per radiant watt. The design is applicable for round and
linear module configurations and is offered in color temperatures ranging from
2700K to 6000K with CRI values from 70 up to 98.
Philips Lumileds Luxeon T/TX family of royal blue LEDs powers the module,
which reportedly achieves wall plug efficiencies of 76%. By comparison the
Luxeon T Royal Blue LED consumes 700 mA at 3V to produce a minimum output of
950mW and typical of 1040mW. The radiometric power (wall plug efficiency) of
the Luxeon T by itself is 53%.
"We're very proud of this landmark performance of 203 lm/W as this was
achieved using our latest commercially available LED technology and Intematix's
remote phosphor," said Jy Bhardwaj, Senior Vice President of R&D at
Philips Lumileds. "This marquee performance simplifies a wide variety of
thermally constrained applications such as 100W A19 bulbs and high lumen candle
lamps, and enables downlights with the highest efficacy in the
According to Intematix, remote phosphor solutions are capable of delivering
high quality, uniform light and omni-directional light distribution to
applications like replacement lamps, high bay industrial illumination and
linear applications like commercial lighting. Through increasing its efficacy,
remote phosphors can lead to reduced material and operating costs.
Tridonic Introduces an LED Module and Two OLED Modules LIGHTimes News Staff
November 5, 2013...Tridonic has introduced the new Talexxengine Stark New DLE LED module and two new Lureon Rep OLED modules. The TALEXXengine STARK NEW DLE system, is comprised of an LED downlight module and associated converter (dimmable or non-dimmable). Tridonic says it is 80 percent more cost effective and at 140 lm/W, much more efficient than its predecessors. The "Best LED Operation" (BLO) mode strikes the perfect balance between efficiency, lifetime and cost.
The module has color tolerance of a 3-step MacAdam Ellipse and a CRI of greater than 80.
It is available in color temperatures of 3000 K and 4000 K. The larger, 65 mm diameter light emission surface of the LED module leads to lower lumens per mm square and makes it easier to reduce the glare from luminaires. The LED module measures 20 mm high.
The Lureon Rep OLEDs, the 20w5-40-DC and the 20w5-40-DL, have a 4000 K color temperature and operate at greater than 50 lm/W. The OLEDs have a color rendering index greater than 90 and a MacAdam 4 color tolerance. The OLEDs thicknesses are less than 3mm and they can provide up to 12,000 lm/m squared. The 20w5-40-DC has a plug contact, and the 20w5-40-DL has a cable contact. Both operate with a typical forward current of 230mA. It apparently has a lifetime of 15,000 hours when running at 70 percent luminous flux.

Seoul Semiconductor to Sell Acrich2 AC LED Modules in Kit Form SSLDesign News Staff
October 8, 2013...Seoul Semiconductor, announced the globally availability of an Acrich kit.
The company says that the Acrich kit is for customers trying to meet the
special design requests of global lighting manufacturers. The kits consist of
Seoul Semiconductors' Acrich Multi-Junction Technology (MJT) LEDs along with
the Acrich Integrated Circuit (AIC) power controller device. Seoul
semiconductor released the Acrich kit because of a surge in requests from
customers who want to make their own form factors. Seoul notes that most of its
mid- to large-sized lighting customers have their own SMT lines and the ability
to source and handle discrete parts; therefore, they prefer to purchase a parts
kit rather than a module. The company asserts that the kit gives designers
maximum flexibility in designing AC LED modules for their unique fixture
Seoul Semiconductor says that the Acrich kit has a high power factor, low
EMI and low THD and can be driven directly from AC line voltages of 100 to 277
volts, and the AIC is available with a smart dimming function. The company
recently announced a 10W, 140 lm/W downlight module using the Acrich2. The
downlight replaced the AC/DC converter (or ballast or driver) with the Acrich
Marten Willemsen, Vice President of Marketing for Seoul Semiconductor, said,
“We have seen a surge of interest in Acrich recently due to its
performance improvement. The new sales strategy to offer Acrich kits is in
direct response to the requests from customers.” He added,
“For broadening our targets and serving the broader global lighting
market, Seoul Semiconductor is now promoting our products through Acrich kit
sales at new price points.”

September 12, 2013...Seoul Semiconductor has announced that its AC-powered Acrich2 LED modules
are now achieving luminous efficacies of 140lm/W, nearly a 20% upgrade from
previous versions. Seoul Semiconductor's latest Acrich2 product consumes 10W
and can achieve 1,400 lumen in cool white and 1,250 lumen in warm white. The
company contends that it achieves the same level of luminance efficacy that a
DC LED module with 180lm/W LEDs would offer. This increased efficacy saves an
additional 20% of power compared to the older versions. In addition, Seoul says
that new arrangements of the LEDs on the board optimize the light pattern for
specialized solutions such as flush-mount ceiling lights for living rooms,
kitchens and porches.
Seoul claims that Acrich2 is the world’s first module using an
on-board IC and multi-junction technology (MJT) LEDs that can be directly
plugged into the wall without a ballast, driver, or converter. Newer variations
of the Acrich2 family include smart functions such as dimming inputs and surge
