Bridgelux® Now Shipping LED arrays with 130 + lm/W Warm White Efficacy Record 160 lm/W Performance Demonstrated on Existing Platforms
http://www.prnewswire.com/news-releases/bridgelux-now-shipping-led-arrays-with-130--lmw-warm-white-efficacy-300021379.html
LIVERMORE, Calif., Jan. 15, 2015 /PRNewswire/ -- Bridgelux, a leading developer and manufacturer of LED lighting technologies, is now shipping its Vero® and V Series™ LED array products with high performing warm white efficacy of 130 lumens per watt (lm/W) and greater. This enhanced performance delivers up to 10% additional energy savings over previous generations. Further, the company has achieved a record warm white efficacy of greater than 160 lm/W on its existing chip on board platforms. With these efficacy gains, Bridgelux continues its tradition of breakthrough LED chip and packaging technology innovation and helps further accelerate the adoption of solid-state lighting.
LED arrays with an efficacy of 130lm/W not only provide a significant return on investment to end customers, but also help OEMs and manufacturers better compete with product offerings that design in state of the art LED based products. The featured 130 lm/W efficacy is now a standard across all Bridgelux Vero and V Series product form factors (3000K, 80 CRI nominal current). Bridgelux Vero arrays provide designers with a best-in-class light source design, a wide range of premium color options, easy integration and installation, reduced manufacturing costs and the industry's best product warranty for LED light source products. Bridgelux V Series arrays leverage the technology and performance of the Vero products in smaller, cost effective packages.
"Our team is committed to programs that improve LED package efficiencies, while maintaining the dazzling high-level of Bridgelux color and uniformity that our customers have come to rely upon," said Aaron Merrill, Director of Product Marketing at Bridgelux. "With advancements in phosphor and die technology we're already achieving efficacies on our current platform that position Bridgelux to push our efficacy leadership well into the future."
With a strong focus on R&D advancing emerging technologies, Bridgelux is a leading innovator in the ever-expanding market for LED lighting solutions. The company is dedicated to the efficient delivery of differentiated, high performance and cost-effective light source solutions that delight the public with aesthetically pleasing, energy saving LED lighting.

Bridgelux is like a box of chocolates, you never know what you're gonna get. Then Cree carefully bins everything but doesn't mark them so maybe you got the bin you ordered, maybe not.

Binning has always been a glass half full or empty kinda argument. Is it better to have a guarantee of a certain performance level or better for one to select a price/performance level. Is CREE really helping us or helping itself to justify it's all over the charts yields by binning or are they showing us how much control and scrutiny they have over their yields. Industry types have been arguing over the value of binning for a while and ultimately the majority of buyers don't want to know about binning. I myself would just like a guarantee of performance in the real world that doesn't require me to buy or rent expensive equipment to see if I'm actually getting that performance in my light/environment.
But here's an interesting little Bridgelux fact that might blossom into something. All Bridgelux Veros, and LD XNovas but not CREEs, have a UPC code that is supposed to have information about the COB like date of production and QA stuff. I'm wondering has anyone tried to use their smartphone to read this UPC and get the info from Bridgelux? Perhaps there is some info in the Veros that allows us to "bin" them? Like is there some lumen per watt ratings associated with this UPC data? Will reading this UPC code allow us to confirm we have a WW Vero that does 160 lm/W? Hmmmm.

Just scanned the 2D barcode-the one at the rear /on the thermal slug- ,
using my notebook's web cam (I have no smartphone...)
( http://sourceforge.net/projects/zbar/ )
Got this :
QR-Code: 30E10K0LX24eK1T201111416
The bold ones are already known ...
The " 4eK1T201111416 " is unknown info ...
Any ideas ?
I'm going to scan a second one ...
Cheers.

I've scanned two more (different) Vero 29 arrays .
QR-Code: 30E10K0LX24eK1T201141416
QR-Code: 30E10K0LX24eK1T201071416
So,from what it seems ....
30E10K0LX2 is the known data (look at the Data sheet )
4eK ,remains unknown ...
1T20 ,I think by a really rough guess that is the actual version of the array ...
Since it is common on all three arrays I've scanned so far ...
And also it 'matches' this :
( T= " time " ? )
Versions : 1.0 , 1.2 and the new one released 2.0
Other than that, the 1416 ending ,also seems to be the same at all the arrays scanned...

Top side product markings and identification improve installation and inventory management
– Alphanumeric part number to the right of the connector port, part number indicates CCT and CRI
– 2D QR Code laser marked for full traceability back to LED wafer
– Easy to read polarity symbols near the solder pads and connector ports
pd... upss..i forget upload the pdf... sorry... pag8

Thought so myself,also ...
It does not fit ..
2 to 8 digits code only ..
full traceability back to LED wafer ????
Wow !
Probably that " 1416 " might be the wafer S/N ..
The digits in front of " 1416" miught be then the S/N of the diodes cut from this particular wafer ( "1416 " )..
Lots of salt grains,though ...
Cheers.

With the time and codes, I see a COB made in 2010 and one in 2011 (my guess).
I never really took much notice to the barcodes until my last build. It's about time we began investigating its purpose

Hmm..Well...With the time and codes, I see a COB made in 2010 and one in 2011 (my guess).
I never really took much notice to the barcodes until my last build. It's about time we began investigating its purpose
The 'problem'; with your guess,
is that first generation of Vero arrays were manufactured during the year 2012
and distributed to the market during the first quarter of 2013.
So a date of 2011 is out of question ...
Probably ,the Vero series arrays existed only in blueprint designs ,back then ...
Let alone the year 2010 ....
Probably, the Vero series arrays existed only inside someone's mind , back then ...
It can not be older than 2012(manufacture date ) or 2013 (shipping date ) ,I'm afraid...
Cheers.

Goes to show how long I've been in the COB business .
Glad to see you still got it StarSailor.
How's your project/research playing out (the one on dimming lights throughout day)?

H – Designates Array Configuration = L
( Low Density Array ?
Because it is one..
156 dies / ( pi * ((29/2)^2 )= 0.236 die/mm^2
At least compared to "Standard Density " CXA3070 = 132 dies / ( pi * ((23/2)^2 )= 0.317 die/mm^2 )
X2= 2 SDCM

COBS News + Info
The P-Series COBs feature 45x45 mils 3-Pad LED flip chips and high flux density in small LES ranging 9~30mm, supporting 24 to 244 watt power ranges (customized CCT/CRI is available upon request). The high "lumen-per-dollar" and low thermal resistance (0.02°C/W to 0.11°C/W) make these COB solutions ideal for high power luminaires, such as spotlights, down lights, high bay lights, street lights and automotive lighting. The P-Series modules are designed to fit existing and inexpensive mechanical holders, optics, drivers and thermal components for simple and low-cost integration into existing packages.
The P25-12S3P (19mm LES / 122 Watt COB) is available for less than $10.00 (US) in OEM quantities. Evaluation quantities are available for immediate delivery with standard lead times of 4 weeks. For more information about FCO P-Series COBs, please visit Flip Chip Opto at www.fcopto.com.
Flip Chip Opto will demonstrate it’s products at Strategies in Light 2015 in Las Vegas. Please visit us at booth 629 between February 24th and 26th, 2015.
Flip Chip Opto Introduces patented 3-Pad LED Flip Chips for High Power Applications
http://www.ledinside.com/products/2015/1/flip_chip_opto_introduces_patented_3_pad_led_flip_chips_for_high_power_applications
Flip Chip Opto, a LED lighting technology company, announced its new P Series of LED Flip Chip Chip-on-Board (COB) products. These high-performance lighting modules are comprised of patented 3-Pad LED flip chips with a Pillar Metal Core Printed Circuit Board (P-MCPCB) to substantially reduce junction temperatures, thermal decay and light emitting surface (LES). Our innovation enables designers to enhance “Lumen-per-Dollar” performance by driving the modules at substantially higher currents reducing LED chip counts, heatsinks and optics.http://www.ledinside.com/products/2015/1/flip_chip_opto_introduces_patented_3_pad_led_flip_chips_for_high_power_applications
