Does LED Lighting Benefit From Less or More SKUs
... One big advantage to LED lighting is its ability to adjust the emission source from full to pretty low with few inherent challenges. That opens the door to a whole new paradigm in 'sizing the light'. In the simplest case, instead of having to specify different maximum lumen outputs,... Read the editorial...

Dialog Semiconductor and Sengled Lighting Partner for Development Of Ledotron-Compliant Smart Lighting Solutions SSLighting Design News Staff
November 21, 2013...Dialog Semiconductor plc a provider of integrated power management, AC/DC,
solid state lighting and short-range wireless technologies, announced a
strategic collaboration with Sengled, a global LED lighting company. Sengled
will serve as Dialog’s first partner for the commercialization of
Dialog’s smarteXite platform. smarteXite integrates the digital dimming
standard – Ledotron™ that is supported by Osram. The collaboration
between Dialog and Sengled includes the exchange of R&D data, joint
development of new product concepts and prototype bulbs, common system level
tests and qualification processes for new smart lighting solutions. Sengled
will create LED lighting solutions using ICs from the smarteXite platform.
“Smart lighting is one of the most important growth segments in
LED lighting, with digital dimming and wireless control as the next major steps
in creating innovative products,” said Johnson Shen, Founder and
President of Sengled. “With Dialog’s smarteXite family of LED
driver products, we can accelerate our innovation cycles and create new
lighting experiences for our customers.”
“We were looking for a fast moving, innovative technology partner
with a global presence. With Sengled, we gain one of the emerging players in
solid state lighting, and a partner that shares our vision and energy for this
market. We are excited to enter into this partnership with the clear target to
make smart lighting real,” Mark Tyndall, VP corporate development
& strategy and GM power conversion business group at Dialog Semiconductor
According to Dialog Semiconductor, the iW6401, the inaugural smarteXite
product, will be the world’s first LED driver IC to support the new
Ledotron dimming standard. Dialog says Ledotron overcomes the limitations and
system performance degradation associated with traditional phase cut dimmers.
The iW6401 is configured via a comprehensive design wizard which programs the
device and generates an optimized bill of materials and component
specification. Dimmers and lamps sold with the Ledotron logo are guaranteed to
operate at full performance regardless of the model and manufacturer.
“With Ledotron we have created a digital dimmer for a digital
light source, which resolves all compatibility and performance issues known
from traditional dimmers. Beyond being retrofit, Ledotron makes LED lighting
future-fit and smart-fit,” said Alexander Burgbacher, CEO of INSTA.
“The adoption of Ledotron in LED lighting is gaining momentum, as the
integration into lamps is made easier with the adoption of the iW6401, the
first in a range of smarteXite products from Dialog.”
In a typical Ledotron configuration, the maximum number of devices that can
be connected to the dimmer is only limited by the peak power of the dimmer. The
communication between the dimmer and lamps is done via baseband data modulation
around the zero crossings of the AC mains voltage. Dialog contends that
lighting systems based on the Ledotron standard are extremely easy to install
and use, and greatly extend the control over LED retrofit lamps by offering
addressing, color control and tunable white features. Volume production for the
iW6401 is expected in the first half of 2014.
DOE Publishes New CALiPER Report on Subjective Evaluation of LED PAR38 Lamps SSLDesign News Staff
November 8, 2013...The U.S. Departement of Energy has published a CALiPER report about the
subjective evaluation of PAR 38 lamps. The report is the first in a series of
four special investigations designed to extend the findings of CALiPER
Application Summary Report 20: LED PAR38 Lamps, which was published late last
year. The new report, CALiPER Report 20.1: Subjective Evaluation of Beam
Quality, Shadow Quality, and Color Quality for LED PAR38 Lamps, focuses on a
subset of the lamps from Report 20, which were separately assessed by members
of the Illuminating Engineering Society of North America. The report is
available online at http://apps1.eere.energy.gov/buildings/publications/pdfs/ssl/caliper_20.1_par38.pdf.
Lighting quality is not easily quantified, and while measurements such as CRI are a
start, as the DOE points out, CRI does not reveal smoothness or color
consistency of a beam. The report states, "Unfortunately, many of these
facets of lighting quality are not easily quantified using readily available
metrics. Thus, it can be difficult for manufacturers to make improvements and
for consumers to differentiate products. Subjective, comparative evaluations
can help to identify product attributes that lead to better lighting quality,
as well as what attributes specifiers consider desirable. "
Researchers at the Pacific Northwest National Laboratory constructed a
demonstration mock-up at their facility in Fairfield, Oregon to learn more
about lighting preferences. Members of the local IES chapter were invited to
view the 26 differen lamps, and were asked to complete a questionnaire that
focused on beam quality, shadow quality, and color quality.
According to the report, "A total of 26 lamps were installed and aimed
at a wall covered with off-white paint typical of a basic commercial space. The
lamps were aimed at pushpins placed in the wall, which were spaced
approximately 10 inches on center to match the spacing of the lamps."
The report describes the demonstration configurations for beam quality,
shadow quality, and color quality. "Each performance attribute had a different
demonstration configuration: beam quality was evaluated with lamps aimed at a
blank wall; shadow quality was evaluated using a series of synthetic flowers
positioned in a vase about 12 inches from the wall; and color quality was
evaluated using an X-Rite Color Checker Classic Card, fabric samples, and a
board with Rosco Scenic Paint."
The results revealed that many of the LED-based lamps compared favorably to
halogen benchmarks in all attributes considered. Some preferences emerged in
the rankings. LED lamps using a single-emitter design were generally preferred
for their beam quality and shadow quality. Conversely, poor color consistency
within the beam, and stray light outside the main beam pattern, were the
attributes most likely to be noted by the observers as negative features.
LED lamps with narrow-spot distributions were generally viewed as having
less-acceptable beam quality than their narrow-flood or flood counterparts,
although there was substantial variation in perceived quality within any of the
groups. Shadow quality was the most universally agreed upon by evaluators with
single emitter B6 lamps generally giving the best shadow quality followed by
diffused B1 lamps. For color quality, the observers generally preferred 3000 K
LED lamps over 2700 K LED lamps.
Noteably, the ranking of color quality did not always match the rank-order
according to the product's color rendering index (CRI). So CRI by itself was
not a perfect measurement of subjective color quality. The report notes that
the effect of CCT and Duv on color appearance should not be overlooked in favor
of choosing a product based solely on CRI—especially when the CRI is
above a minimum threshold (e.g., 80). In the future, the adoption of new
color-quality metrics should help manufacturers design better products and
specifiers choose better products.
The DOE reports that LED PAR38 lamps still have room for improvement in even
the best performing lamps. Another conclusion that the report made was that
because of substantial variability in both LED PAR 38 lamps and halogen lamps,
buyers will have to make careful purchases. The report points out that some of
the factors to consider before choosing a lamp include: electronic
compatibility with control equipment, dimming performance, form factor,
The report points out that lumen depreciation and color shift of 40 lamps is
currently being monitored for an extended period of time using the Lumen
Maintenance Test Apparatus (LMTA) at PNNL.
Smart Vision Lights Lab Qualified as Certification Facility for International Safety Standards LIGHTimes News Staff
September 26, 2013...Smart Vision Lights of Muskegon, Missouri USA, a company known for
manufacturing of machine vision lights, was recently qualified as a Level IV
LED testing and certification facility by Intertek, a leading international
provider of testing, inspection, and certification services under Interteks
SATELLITE Data Acceptance Program. The new Level IV LED light testing and
certification lab means that all Smart Vision Lights LED light sources are
tested and documented to meet international light performance and safety
standards, including IEC-62471, Photobiological Safety of Lamps and Lamp
Systems. Smart Vision Lights says its customers are already enjoying the
benefits of buying LED lights that are tested to the IEC-62471 standard.
"Cognex products needed to have a UL certification, and in order to
obtain this, UL required Cognex to have our products IEC-62471/RP27
certified," explained Nathan Caughel, product marketing specialist at
Cognex Corporation. "Smart Vision Lights provided this certification,
further demonstrating their value as a lighting supplier in the machine vision
The company points out that all lights sold in Canada, the European Union,
and Asia are required to be tested to the IEC-62471 standard to protect workers
from injuries and blindness caused by exposure to ultraviolet (UV), visible,
and infrared/thermal electromagnetic radiation. In fact, the company says that
if a manufacturer applies a CE or CCC mark to an LED light for sale in Europe
and China, respectively, without supporting documentation of IEC-62471
compliance, the equipment can be recalled and prohibited from sale.
Furthermore, the manufacturer can also be liable for fines and other damages.
Although the U.S. does not require IEC-62471 compliance today, UL regularly
requires IEC-62471-compliant LED lights for systems that could be sold in
Canada or other non-U.S. markets.
According to David Spaulding, President of Smart Vision Lights, compliance
with IEC-62471 is becoming a hot button for light manufacturers, particularly
advanced light manufacturers in machine vision and industrial automation
industries. Spaulding says It takes considerable investment for a company to
qualify as an Intertek light-testing laboratory under the SATELLITE Data
Spaulding said, "Our customers can be confident that their systems,
products, and investment containing Smart Vision Lights products are fully
compliant with international standards and safe for sale across all global
markets. Interteks SATELLITE Data Acceptance Program integrates speed,
flexibility, and cost-effectiveness into the product development process by
accepting internal laboratory test data of qualifying customers."
Smart Vision Lights LED testing lab includes a new Gooch & Housego
Spectroradiometric system consisting of an OL 750-M-D double monochromator with
integrating sphere, including germanium, lead sulfide, and silicon
high-sensitivity detectors for performing highly accurate optical radiation
measurements. This allows the company to independently measure and validate
IEC-62471 data including radiance and irradiance of optical radiation from
200nm through 3000nm wavelengths. The entire lab will regularly undergo
periodic Intertek audits to maintain its Level IV status.
