5:00 PM – 6:00 PM CET

Valued for their relatively small lumen package, MP LEDs are uniquely suited for linear and distributed lighting applications such as LED tube lighting and troffers. As their cost proposition and performance improve, MP LEDs started to penetrate retrofit applications (e.g. LED light bulbs), industry (low and high bay lighting) and in retail shops and hospitality segments. Each of these applications have specific needs which can be met with LEDs designed with the end application in mind. An example would be a high efficacy MP LED with good quality of light (min 90 CRI) for use in retail shops. We expect that in the future the lighting market will be served mainly by these ‘application-specific’ LEDs. In this webinar we will take a close look at MP LEDs, the factors that have led to their use in lighting applications and what we can expect in terms of their proposition and usage in the future.

Philips Lumileds Signs Partnership with MechaTronix for LED Thermal Management Solutions

With the launch of the newest generation Philips Lumileds Luxeon Chip-On-Board (COB) LED modules there was an immediate need for a wide range of standard LED coolers. In the cooperation with MechaTronix Philips Lumileds found a practical and easy way to launch a wide range of standard LED coolers fitting mechanically with the various dimensions of the Luxeon COBs and matching the cooling capacities needed for the whole series.

philips-lumileds-luxeon-cob-family

Six passive coolers have been launched, ranging from a diameter of 50mm for the Luxeon COB 1203 and 1204, over a diameter 70mm and 99mm for the COB 1204, 1205 and 1208:

With this passive LED cooler range MechaTronix aimed at spot, track and down light designs from 600 lumen all the way up to 4.500 lumen in a small size extrusion profile. The ModuLED Xtra LED coolers are developed in this way that there is an optimal balance between creating cooling surface and leaving enough intermediate space for free air convection.

In this way MechaTronix was able to reach a ModuLED Xtra cooling performance of 1.02°C/W in a package of only 99mm diameter and a height of 80mm, and keeps the Luxeon 1208 COB running at 4.800 lumen at an ambient temperature of 40° Celsius below a case temperature of 80° Celsius.

For those applications running at an extreme high ambient temperature, two active coolers packages where designed:

The IceLED Xtra active LED coolers are developed in a package for indoor low bay use with an extremely low noise factor, this delivering a cooling performance of 0.46°C/W.

This makes them extremely suitable for spot, track and down light designs in office, shop environments and silent rooms where extra noise has to be avoided

All ModuLED and IceLED coolers are foreseen from direct mounting patterns for the various Philips Lumileds Luxeon COB’s, but also offer Zhaga book 3 mounting holes so designers can use COB LED holders if they require solderless mounting of the COB’s on the coolers

MechaTronix performs thermal compatibility tests on all combinations of the Luxeon LED COB’s with the various standard coolers:

A major point of improvement according Koen Vangorp, General Manager of MechaTronix, is the extreme low internal thermal resistance of the Luxeon COB’s. “Philips Lumileds clearly understood the mission of developing high lumen packages in combination with a low thermal resistance. Maybe it is not so obvious to understand what this means because most LED manufacturers offer an external thermal measurement point and all publish similar numbers for these, but the consequences are enormous. With these low thermal resistances from junction to case Philips Lumileds is able to keep their junctions easily 10 to 15 degrees Kelvin lower than most chip-on-board modules on the market. And that immediately affects the life time of the LED dies in a very positive way. Either designers can take advantage of this by using smaller LED coolers, or just use the same LED coolers like they did before but gain on life time.”

All MechaTronix LED coolers are off-the-shelf available through their worldwide distributor and agent network.

Osram Joins Cree and Philips Lumileds in "Hot-Binning" with Oslon Square

Osram has started hot binning the Oslon Square which reportedly withstands high ambient temperatures particularly well. Osram notes that to ensure that the colors of several LEDs in a luminaire remain uniform even at higher temperatures. They are measured and binned at 85 degrees Celsius (°C), a temperature that comes very close to that encountered in lighting applications within buildings, in everything from spotlights to retrofit light sources. For this reason, Osram contends that measuring and binning at operating temperatures of 85° C is of great significance to customers who further process the light-emitting diodes into luminaires. According to Osram, its OEM customers receive precise information on parameters such as luminous flux or color stability, which they need to optimally define the properties of their products. Osram says it has optimized the heat dissipation of the Oslon Square to allow an increase in the junction temperature.

“With our new conversion technology, we can produce significantly thinner converter layers. The thinner layers better dissipate the heat, thus enabling the higher temperatures in the LED,” says Ivar Tangring, SSL Product Development at Osram Opto Semiconductors. Osram claims that with this heat dissipating structure, Oslon Square can reach a lifetime of considerably more than 50,000 hours even at high temperatures of up to 135° C in the LED.

In addition to longer life, Osram says that the improved temperature behavior leads to higher luminous efficacy in the application. “This luminous efficacy, meaning the ratio of luminous flux to applied electrical power, helps our customers to significantly optimize the price/performance ratio of their luminaire solutions,” Tangring emphasizes. Also, thanks to the higher permitted junction temperatures, fewer large heat sinks are required, the company pointed out

The Oslon Square comes in a color temperature ranging between 2,400 (warm white) and 5,000 Kelvin (cool white). The color rendering index of the LED is over 80 and the luminous flux is an impressive 202 lumens (lm) at 3000K operating at 700mA. This translates to about 100 lm/W at 2.9 V. Currently, Osram says that the new LED is undergoing extensive quality testing including the certification process under the LM-80 long lifetime standard. The results of the 3,000 hour test are expected at the end of the year, those of the 6,000 hour test in spring 2014.

LED hot binning

the-xlamp-mt-g-shown-here-was-the-first-LED-to-be-binned-hot-at-85c

As the name implies, hot binning is binning the LED lamps at a higher temperature than the conventional 25°C. The LED manufacturers who have decided to launch new products binned at an elevated temperature have converged on 85°C as the new conventional binning temperature. Though 85°C, like 25°C before it, is somewhat arbitrary, it has one major advantage it is a lot closer to the typical operating temperature of many solid-state lighting luminaires than 25°C.

Binning at 85°C makes the initial part of the design process slightly easier and more intuitive. For example, if a designer were working on an LED system that needed 1,000 lumens at an 85°C temperature, then he or she could simply select 10 LED lamps with a luminous flux of 100 lumens per LED, binned at 85°C. Thus, hot binning makes it easy to estimate the performance of these LED lamps in this real-world situation. On the other hand, if the LEDs were binned at 25°C, the same 10 LED lamps would need to be binned at 114 lumens each and de-rated per the LEDs mathematical framework (Fig. 3) to arrive at the same 1,000 lumen goal at the system level.

So, the good news is binning at 85°C makes the first-pass math more intuitive. The bad news is you still have to do the same math if your system runs or ever runs at any temperature other than 85°C. Examples of this would be outdoor luminaires (60° to 65°C is much more common) or freezer cases (20° to 25°C is typical) or downlights in insulated ceilings or almost any retrofit bulb (often over 100°C). In each of these cases the value of binning at 85°C is lost and the designer is back to doing the same math from a new mathematical framework where, arbitrarily, 85°C is now set to equal 100%.

Intematix and Philips Lumileds announce 203lm/W module demo

Philips Lumileds Luxeon T/TX LEDs combined with an Intematix remote-phosphor optic deliver light source efficacy of 203 lm/W in an SSL module developed by the duo as a technology demonstration.

intematix-and-philips-lumileds-announce-203-lumens-per-watt-module-demo[/caption]

Intematix has announced that one of its remote-phosphor optics combined with Philips Lumileds Luxeon T/TX LEDs in a technology demonstration has yielded efficacy of 203 lm/W at the light source level. The duo built the module, that at least for now will not be commercially sold, although the remote-phosphor optic and the LEDs used in the demo are readily available from the two companies to developers of solid-state lighting (SSL) products.

The demonstration relied on a rather cool CCT of 6000K that Intematix called a daylight spectrum, and that the company noted is located on the black-body curve, albeit with a CRI of 70. Certainly the cool CCT and relatively low CRI make high efficacy more easily achievable, although the accomplishment is still noteworthy.

“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 today,” said Yi-Qun Li, CTO of Intematix. “This result is a significant step along our innovation roadmap for phosphor solutions.”

Last year we had dueling articles from Cree and Intematix on the merits of remote-phosphor technology. We also had a recent feature in which Xicato asserted the color consistency advantages of remote phosphor.

Of course, the obvious question is why did Intematix and Lumileds decide to make a public announcement about the demonstration in module form, when apparently neither will offer the module for sale. Senior director of strategic marketing Julian Carey said, “Intematix remains a phosphor solutions maker. The module was developed as a technology demonstration to show how much performance can be obtained using remote-phosphor solutions.”

Lumileds certainly welcomed the chance to demonstrate the blue-pump LEDs in the Luxeon T/TX family that deliver wall plug efficiency of 76%. “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 industry,” said Jy Bhardwaj, senior vice president of R&D at Philips Lumileds.

Still, the question remains as to how popular remote-phosphor technology will be going forward despite any efficacy advantage. Lumiled’s parent Philips Lighting has moved away from remote phosphor despite success with designs such as the L Prize lamp. But Intematix does have new optics that have a near-white look in the off state.

“We expect more of our customers to come out with systems that have high performance using our remote phosphor solutions,” added Carey. Lumileds Bhardwaj said, “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.”

Cree, Philips Lumileds, and Luminus Devices extend COB LED technology

Luminus Devices, Philips Lumileds, and Cree have all made recent chip-on-board (COB) LED technology announcements that in aggregate span increased lumen output in both small and large LED packages. The variety of options in chip-on-board LED arrays continues to expand, both in brighter LEDs...

The variety of options in chip-on-board LED arrays continues to expand, both in brighter LEDs with smaller light-emitting surfaces and in larger components with maximum flux output. Luminus Devices, Philips Lumileds, and Cree have all made recent chip-on-board (COB) LED technology announcements that in aggregate span increased lumen output in both small and large LED packages. Cree announced a brighter LED with a 23-mm light-emitting surface (LES) and a new 30-mm part in the CXA family. Lumileds announced a 10% gain in performance across its entire COB line. And Luminus Devices entered the COB segment for the first time with its Xnova family charting a new path to serve general solid-state lighting (SSL) applications.

Cree CXA3590 and CXA3070

cree-cxa3070-LED

Cree has now upgraded its 23-mm family with the CXA3070 LED extending the performance range to 11,000 lm at 85° operating temperature. SSL manufacturers that used the prior CXA3050 LED can drop the new family member into existing designs with little or no change required and deliver higher-performance products. “The high-performance CXA3070 LED array enables us to offer metal-halide replacements that exceed the efficiency and life of the technology they replace,” said David Gershaw, president, RemPhos Technologies LLC. “Cree CXA LED arrays set the industry standard for integrated arrays, providing excellent efficacy, reliability, and light output.” The CXA3590, meanwhile, is Cree’s largest COB LED yet, delivers 16,225 lm, and is designed to replace 250W metal halide (MH) sources. “We are excited that Cree is extending the CXA family because it enables us to address more applications with a single, easy-to-use platform,” said David Lin, general manager, Yah Juang Lighting Technology. “The CXA3590 LEDs allow us to address high-lumen applications with a single LED, a feat which would have taken hundreds of other LEDs to accomplish.”

Lumileds bumps COB performance

philips-lumileds-luxeon-cob-family

Philips Lumileds only entered the COB space back at Lightfair in May offering components with an LES of 9, 13, or 15 mm. “Just one quarter into volume product deliveries, we have increased Luxeon COB performance by +10%, which speaks to the rapid rate at which we upgrade the lumen output and efficacy of our products,” said Eric Senders, product line director at Philips Lumileds. The products now span the range of 1000 to 7000 lm with typical efficacy of 130 lm/W. A 2200-lm 9-mm LED in warm white delivers 2200 lm at 100 lm/W. The company also asserts that its metal-core substrate delivers better thermal performance than competitive products and allows SSL manufacturers to utilize 40% smaller heat sinks.

Luminus enters COB market

luminus-xnova-led-family

Luminus Devices’ entry into the COB arena is somewhat a surprise. The company had previously focused on building larger individual LED die to serve high-lumen-output applications. Indeed, the company contributed a feature article on its round monolithic emitters in March 2013 that essentially questioned the value proposition of COB technology. Luminus has since been acquired by Sanan subsidiary Lightera. The new Xnova LED family is the combined work of Luminus and Lightera, and, according to a company spokesperson, represents “a change in direction for Luminus with regard to general lighting.” Luminus will continue to supply its larger-die LEDs into entertainment, display, medical, ultraviolet (UV), and other specialty applications. The Xnova family is being debuted this week at the Hong Kong Lighting Fair with products spanning the range from 350 to 10,000 lm. Cool white efficacy is 134 lm/W and warm white efficacy is 120 lm/W. CRI ranges from 75 to 95. “The Xnova family enables further adoption of LED technology into mass markets by providing our customers with outstanding technical performance and superior value,” said Decai Sun, chairman and CEO of Luminus. “Leading lighting companies around the globe are already designing their next-generation lighting solutions based on our new technology.”

Philips Lumileds Introduces Luxeon TX - New High-Flux Emitters Transform Directional Luminaires

LUXEON_TX_2

Today Philips Lumileds introduces LUXEON TX emitters, which deliver high luminous flux and maximum efficacy for a variety of directional and omnidirectional lighting applications. “These emitters are truly transformative in that they enable customers to achieve performance metrics — such as a true 50W equivalent MR16 lamp at 2700K that meets ERP/DIM2 requirements — which LEDs simply could not meet previously,” said Kathleen Hartnett, Product Line Director for Emitters at Philips Lumileds.

“We use the term ‘extreme efficacy’ because of the remarkable performance customers can expect from these emitters,” said Hartnett. “For instance, outdoor fixture manufacturers who need 4000K at 70 CRI are taking advantage of the LUXEON TX 360 lm output 1.0A and 85˚C to decrease overall system cost, but have the ability to drive the same part 350mA to deliver 155 lm/W LED efficacy and enable streetlights with a system efficacy of more than 120lm/W.

The LUXEON TX platform is available in a range of CCTs and CRIs to satisfy the most exacting requirements of downlights, high bay and low bay lighting, indoor area lighting, outdoor lighting and replacement lamps. In addition, for improved design flexibility, Philips Lumileds has added a minimum 85 CRI option so designers can further differentiate their product lines.

“Designers have typically had to choose between the lower efficacy associated with a 90 CRI LED or the poorer color rendering associated with an 80 CRI LED. Now LUXEON TX 85 CRI emitters bridge that gap by providing high CRI with increased efficacy in a full CCT range from 2700K to 5000K.”

For applications that require a minimum 90 CRI, LUXEON TX delivers up to 100 lm/W warm white light (3000K CCT, 90 CRI and 700 mA at 85˚C).This level of efficacy at 90 CRI enables superior performance for luminaires that must adhere to increasingly stringent lighting standards such as the CEC’s California Quality LED Lamp Specification.

LUXEON TX

LUXEON TX emitters are illumination grade LEDs designed to deliver high efficacy with high flux density to enable directional and high-lumen applications. With Freedom from Binning and extreme performance, LUXEON TX emitters ensure system color point accuracy and provide lamp and luminaire designers with the flexibility to optimize for the highest possible efficacy or for low system cost, in vast Correlated Color Temperature (CCT) ranges at 70 CRI from 3000K to 6500K, at 80 and 85 CRI from 2700K to 5000K, and at 90 CRI from 2700K to 3000K.

Mid-power LEDs performance in 2013 has been stellar. Mid-power LED has become the mainstream for interior lighting, including retrofit bulbs, remarked Sean Zhou, Asia Regional Marketing Director, Philips Lumileds during the LEDforum Taipei 2013. Large volume of mid-powered LED are applied in downlights and panels.. Indoor lighting applications for downlights and panels is hoped to turn to mid-powered LEDs in the future. The Philips Lumileds flip-chip high voltage currents and small sized packaging can achieve better luminosity (lm/w) and price/performance ratio (lm/$) through. The company plans to introduce flip-chip technology into the mid-power LED market in the future.

It is evident that mid-powered LED product line is drawing most attention from the market this year. Zhou pointed out mid-powered LEDs have become mainstream for interior lighting and is already largely applied in retrofit bulbs, downlights, and panels. Mid-powered LEDs can even be seen applied in outdoor lighting, there are cases of the product being used in street lights now. It is still unclear as to whether mid-power LEDs or high-powered LEDs will become the mainstream because different lighting fields require support from different power products.

Philips Lumileds plans to introduceflip-chip technology to mid-powered LEDs in the future. The first chip-scale-package product LUXEON flip-chip by Philips Lumileds made the package size nearly equal to the size of the chip. Reducing the size of the package is conducive towards increasing flexibility of application designs, and can reach a better luminosity (lm/w) and price/performance ratio (lm/$) performance through high voltage currents and small sized packaging.

The company’s LUXEON flip-chip use of inverted CSP technology can omit the wiring process. This not only allows the product to achieve high voltage and at the same time reduces package size, while increasing package density. Philips Lumileds is optimistic about the flip-chip’s advantages in luminosity efficacy, lm/$, and package size. The company plans to use flip-chip technology in mid-powered LEDs.
