Flip Chip Opto Debuts Three-pad LED flip Chips
LIGHTimes News Staff
January 29, 2015...Flip Chip Opto of Fremont, California USA,, announced its new P Series of
LED Chip-on-Board (COB) products. The lighting modules are comprised of the
company's patented 3-Pad LED flip chips with what the company calls a Pillar
Metal Core Printed Circuit Board (P-MCPCB) to significantly reduce junction
temperatures, thermal decay and light emitting surface (LES).
According to the company, the innovation allows designers to improve
“Lumen-per-Dollar” performance by enabling the driving of the
modules at substantially higher currents, thereby reducing LED chip counts,
heatsinks and optics.
The P-Series chips measure 45x45 mils and feature high flux density in small
LES ranging from 9~30mm, supporting 24 to 244 watt power ranges (with
customized CCT/CRI available upon request). The high "lumen-per-dollar" and low
thermal resistance (0.02°C/W to 0.11°C/W) reportedly make the P-Series COB
solutions perfect for high power luminaires, including spotlights, high bays,
down lights, street lights, and automotive lighting. The company designed the
modules to fit existing and inexpensive mechanical holders, optics, drivers,
and thermal components for integration into existing packages.
The P25-12S3P (19mm LES / 122 Watt COB) is available for under $10.00 (US)
in OEM quantities. Evaluation quantities are available for immediate delivery
with standard lead times of 4 weeks. Flip Chip Opto will demonstrate its
products at Strategies in Light 2015, February 24th and 26th, 2015 in Las
Netherlands Health Council Advises More Research into LED Lighting Health Effects
LIGHTimes News Staff
January 29, 2015...The Netherlands Health Council warns that blue LED light can cause health
issues, according to an article
in NLTimes. LEDs are increasingly common for backlighting of
smartphones and tablets, and they are being more widely used in new LED-based
lighting. The Health Council released an investigatory and advisory report
which stated that a person's biological clock “controls numerous
physiological and behavioral processes”. The report notes that this
biological clock “…operates autonomously, but may be affected
due to external factors. One of the most important factors is
The researchers discovered that that people are interfering with their
melatonin (sleep hormone) production and thus reversing their biological clocks
through exposure to bluish LED light in the evenings. Other recent studies have
had similar findings.
The report notes that the short term effects of evening exposure to blue
wavelengths of light is a shorter period of sleep, reduced attention, and an
increased risk of accidents.
The report, which seems to make egregious leaps in medical supposition, says
that potential long-term effects of blue LED light exposure (presumably related
to the reduced melatonin production, and sleep deprivation) could include the
development of cardiovascular disease, obesity, mental disorders, and
The council contends that consumers must be warned about these risks. The
council calls for research and development into products that emit less blue
light and further research into the health effects of LED light.

Urban Barns Announces Update on LED Research and Development at McGill University
LIGHTimes News Staff
January 29, 2015...Urban Barns Foods Inc., a Montreal, Canada-based food producer dedicated to
growing fresh vegetables year-round, has updated shareholders on its research
and development activities at McGill University￼. The Biomass Production
Laboratory at McGill University, with support from Urban Barns, is paving the
way for research in urban agriculture. Recent innovations with LEDs has brought
about this new area of research of using LED lighting as a plant energy source.
LED lighting systems can control wavelengths emitted. This allows for research
on the impact of different spectral wavelength combinations on plant growth and
development. Compared to conventional lighting techniques when growing
tomatoes, an arrangement of lights with red and blue wavelengths has
significantly increased growth, improved morphology, and suppressed plant
Last February, Dr. Lefsrud with support from an industry partner, Urban
Barns, was awarded a NSERC research grant to develop improved LED lighting
systems for their indoor Cubic Farming facility. The Cubic Farming method
rotates troughs on which various species are grown while controlling
temperature, humidity, irrigation, and lighting.
According to Dr. Lefsrud, results reveal significantly faster growth with
LEDs than with conventional lighting systems. "Once implemented at a large
scale, this project has the potential to provide high yields of nutritious,
sustainable, fresh and locally grown food year-round, regardless of regional
climate," Dr. Lefsrud stated.
Researchers at McGill University's Macdonald Campus's Bioresource
Engineering Department have published numerous scientific papers about the
effects of LED lighting. The research examined the concentration of
β-carotene and other phytochemicals in plant's growth cycles, and they
determined how plant production of these antioxidants may be increased using
LEDs. Specifically, the research focused on the impact of red, blue and amber
LEDs to increase production and nutritional values.
Dr Lefsrud noted, "We have been very surprised by the increase in
anthocyanin levels in lettuce with small changes in the ratio of red, blue and
amber LEDs." However as Dr Lefsrud explains, "Not all plants exhibit the
same response to these LED wavelengths and research is continuing in the
Urban Barns facility located in Mirabel, Quebec opened in June 2014, after
benefiting from Biomass Production Laboratory expertise. Urban Barns
subsequently began selling pesticide and GMO-free lettuce to clients in Quebec
and Ontario. A Cubic Farming research unit has been assembled on the McGill
University's MacDonald campus help measure the photosynthetic efficiency of
horticultural plants and further develop LED technology￼ to maximize
growth and plant production.
COB LED Market to Nearly Triple from 2014 through 2020, According to Strategies Unlimited
LIGHTimes News Staff
January 27, 2015...Strategies Unlimited latest report about the COB LED market predicts that
the market for COB LEDs will grow from $1.54 billion in 2014 to 4.35 billion in
2020. The research firm also predicts that the COB LED market will grow by 40
percent in 2015 compared to 2014.
The company contends that the long term growth in the COB LED market is
mainly due to the increased penetration of COB luminaires and lamps into some
specific lighting applications, such as spotlights and downlights.
Martin Shih, annalist at Strategies Unlimited noted,"With better light
distribution and design flexibility, we expect a significant growth for COB,
especially in directional lighting applications."
Shih points out that COB LEDs are wide-area emitters, making them perfect
for applications such as high bays, downlights, spotlights, and street
Shih says that in certain applications, heat management and government
regulations are the primary impediments to driving demand. One such initiative
that could slow the penetration rate is the “Dark-Sky Movement,”
which seeks to reduce light pollution.
While LED lighting is known to be the main driver of the COB LED market
growth, the company says that LED packagers must catch the growth of the COB
market by application and by region to explore the market opportunities.
Because the market for COBs is poised to see growth, the company forecasts that
the markets for some specific applications will have 11%~28% CAGRs from 2015 to
2020. According Strategies Unlimited, COBs will eventually dominate the market
in some lighting applications.
China LED Chip Production to Soon Exceed Taiwan's for First Time
January 27, 2015...China's production value of LED chips is expected to exceed Taiwan's for the
first time in 2015 or 2016, according to a Digitimes article that cited
Taiwan industry sources. The article noted that while some China-based LED
chipmakers withdrew from the market, larger ones including HC SemiTek, San'an
Optoelectronics, Aucksun, and Suzhou Nanojoin Photonics used government
subsidies to expand production capacities.
The subsidies specifically went into adding MOCVD systems in 2014. About 155
to 170 MOCVD systems were added for additional LED production in China in 2014.
In total China currently has 1172 MOCVD systems. More than 250 MOCVD systems
are expected to be added for LED production in 2015. Most will go into
producing 4-inch LED epitaxial wafers.
With the addition of 155-170 MOCVD sets in 2014, there are 1,172 sets in
total in China currently, according to the article. In 2015, more than 250
MOCVD sets, mostly for making 4-inch LED epitaxial wafers, are expected to be
added, the industry sources noted.
China-based LED chip makers including subsidiaries established by
Taiwan-based LED chip producers reportedly boosted LED chip production by about
40% in 2014 to about US$1.95-2.24 billion. The total production value of LED
chips from china is expected to grow by 35% in 2015.

Hubbell Lighting Introduces LED Fixtures for Horticulture
LIGHTimes News Staff
January 27, 2015...Hubbell Lighting of Greenville, South Carolina, launched an LED fixture
specifically designed to deliver nearly 100% usable light for plant growth with
virtually no wasted energy. The product from the company's Industrial Lighting
division is called NutriLED. The company says that NutriLED provides spectrally
tuned light to optimize growth and germination for virtually any indoor
Hubbell points to recent studies showing increased growth rates and yields
from growers utilizing LED lighting. According to Hubbell, plants only absorb
the blue wavelength and red wavelength portions of light, not utilizing any of
the other wavelengths. NutriLED reportedly creates an ideal blend of red and
blue wavelengths and light intensities for chlorophyll absorption. Hubbell says
that this ideal light combination means virtually no wasted goes into producing
spectrums of light that don't benefit plant growth. According to the company,
NutriLED provides up to 88% energy savings compared to non-LED grow lights and
delivers enormous maintenance savings and greatly minimizes waste.
An additional benefit of the NutriLED lighting is the tremendous reduction
in radiant heat from conventional lighting, which can lead to a 50% reduction
in water usage and can also lead to a complete elimination of supplemental HVAC
cooling loads for some applications.
The NutriLED allows for multiple mounting configurations running linearly or
parallel and to light plants from virtually any angle. Additionally, the
NutriLED’s unique optical design offers controlled, uniform illumination
with a 60-degree beam spread that yields a 1:1 spacing ratio.
