Maintenance Economics: How LEDs Improve the Bottom Line for Commercial and Industrial Users
By Tracy Earles, VP, Marketing and Sales, Albeo Technologies

It’s not just about the kilowatts. Most people are now aware of one key benefit of LED lighting - its efficiency. LED lighting long ago surpassed incandescent efficiency and is now approaching and even surpassing the efficiency of linear fluorescent and metal halide. However, there are many other benefits to LEDs including lasting five to 10 times longer than fluorescents, consuming less energy while on, are fully dimmable, contain no hazardous mercury, are nearly unbreakable, are free of annoying flicker and buzz and are safer, operating on low voltage DC, with no glass or vacuum.

Infrared Ostar Lighting LEDs Provide Compact, Powerful and Efficient Radiance
With six powerful thin-film chips and a hemispherical lens, the new Infrared Ostar Lighting LED from Osram Opto Semiconductors produces 3.5 W of optical output power at an operating current of 1 A. The beam angle and radiant intensity can be varied with standard secondary optics which are readily available on the market. The hexagonal honeycomb shape of this high-power component enables multiple IR LEDs to be combined to form a large space-saving matrix so that the output power can be increased many times. Major applications for the IR OSTAR Lighting LED include industrial lighting for camera-based surveillance systems such as CCTV and intelligent transportation systems (ITS).

The IR Ostar Lighting LED is available in two wavelengths. At 850 nm, the SFH4750 is an optimized union of maximum spectral sensitivity for CCD and CMOS cameras with suppressed visibility for the human eye. The SFH4751 is a version with a wavelength of 940 nm, to which the human eye is almost insensitive. This model is used in applications where visibility of the light source must be eliminated. “We were able to bring the infrared Ostar Lighting quickly to market because of the synergies among the various technologies at the product development stage,” said Harry Feltges, Marketing Manager for Infrared Components at Osram Opto Semiconductors. “The package is the same as our popular white Ostar Lighting, so our customers can take advantage of the shared thermal and mechanical designs.”

With their high optical output, both versions of the IR Ostar Lighting LED are good choices for industrial lighting illumination units for CCTV systems. These systems are used to improve public safety on the streets, at railway stations, at airports and in schools, and also to protect museum exhibits against theft. These IR LEDs have a very long lifetime, even in pulsed mode applications. They are, therefore, suitable as light sources for intelligent transportation systems such as traffic monitoring, toll systems and automatic number plate recognition (ANTR).

Leadis Technology Launches New LED Driver Family With 40V-Integrated Synchronous Rectifier
Leadis Technology, Inc., an analog and mixed-signal semiconductor developer of LED drivers, and Touch ICs for mobile consumer electronic devices, has announced sample availability of the LDS8710, an innovative inductor-based, high-efficiency LED Driver that eliminates the expensive external Schottky diode normally used in the rectification loop. The LDS8710 is the first in a family of drivers that includes the LDS8716 and LDS8714. The LDS8710/16/14 drive up to 10, six and four LEDs in series, respectively, from a single-cell Lithium-Ion battery.

The LDS8710 family is well suited for applications such as Smart Phones, Portable Multimedia Devices, Personal Navigation Systems and Digital Photo Frames where battery life, display size, resolution and brightness are critical.

Each device in the family features a patent-pending, integrated synchronous rectifier which eliminates the external Schottky diode and the need for complicated and costly isolation FETs. This reduces the bill of material and footprint of the display sub-system, and simplifies the design-in process and time to market of the end product.

The LDS8710 drives up to 10 LEDs with factory-preset maximum LED current values of 20, 25 or 30 mA with 1 percent accuracy. This eliminates the need for an external sense resistor and further simplifies the system. Since the LDS8710 family operates at a fixed switching frequency, small low profile passive components (10 to 22 µH inductors and 0.1 µF high voltage ceramic capacitors) can be used, which further reduces the system's bill of material and allows for a thin backlight unit profile. Moreover, the use of the 40 V rated integrated synchronous rectifier makes the efficiency dependent upon only one external component parameter: the inductor DCR. This further simplifies the system design, while simultaneously achieving greater than 83 percent efficiency.

"We are pleased to bring to the market the first LED Driver family featuring our patent-pending integrated synchronous rectifier. This novel architecture has been thought out with one main goal in mind: simplify our customers' design experience and accelerate their time-to-market," said Donato Montanari, vice president at Leadis. "By reducing the number of external components, allowing customers to pre-select maximum current ratings, implementing robust protection (over voltage, under voltage, over temperature and over current) and offering wide PWM dimming frequencies (100 Hz to 10K Hz), every feature of the LDS8710 family is meant to improve our customer's time-to-market and reduce their bill of material."

Tyco Electronics Adds Wire-To-Board Capability to LED Connector Line
Tyco Electronics has introduced new wire-to-board plug connectors and board-to-board connectors to its family of hermaphroditic blade and receptacle connectors. The connectors are designed to make connecting of aluminum-clad printed circuit boards, commonly used for LED lighting applications that include lighting controls and LED light modules, faster and easier.

The new plug connectors use tin-plated brass crimp-snap contacts for 18 to 22 AWG (0.3 to 0.9 mm2) stranded wire and a 94V-0-rated thermoplastic housing. The plug connector mates with board-mount connectors and features positive latching for a secure connection.

“As LED lighting continues to expand dramatically, manufacturers are looking at solutions to lower the costs of assembling and maintaining lighting systems,” said Alexander Hunt III, product manager. “With the new series of hermaphroditic blade and receptacle connectors adding wire-to-board capabilities, customers now have a complete end-to-end solution for fast, flexible connecting of lighting modules.”

The low-profile surface-mount board connector uses a hermaphroditic blade and receptacle design to allow LED printed circuit board strips to join with more flexibility than traditional post-and-receptacle headers. Connections can be made by sliding the two boards together horizontally or vertically. The unique capability to slide the two boards together vertically makes replacement of a board in mid-strip easier by lifting up the strip to be replaced and lowering in the new one.

The same board-mount connector is used for both board-to-board and wire-to-board connectivity. The hermaphroditic design results in only one board-mount part needing to be inventoried and simplifies design by using the same footprint on both ends of the strip. Contacts are supplied in reeled form for processing by high-speed terminating equipment.

Connectors are available in 2, 4, or 6 positions. They are rated to 6 amps and 125 VAC/VDC, with an operating temperature range from -40°C to 105°C. They are UL/cUL recognized in File No. E28476.

AIXTRON and Semileds Report First Success with UHB Blue LEDs on 6-Inch Sapphire Wafers
A collaboration between AIXTRON and Semileds has resulted in the successful fabrication of GaN-based blue LED chips on 6-inch sapphire wafers. Not only were optical results encouraging but also the process is sufficiently close to production compatibility that the company should soon be able to reap the rewards from larger wafers.

The 6-inch sapphire wafer process is based on MOCVD and a series of follow-on device fabrication steps through to final test. Specifically, the LED structure was deposited on a 1,000 µm thick 6-inch sapphire substrate using an AIX 2800G4 HT MOCVD reactor in the 6 by 6-inch configuration.

Dr. Chuong Tran, president and COO of Semileds, said, “Brightness and efficiency are encouraging even though we are only a small step away from our existing and mature 4-inch sapphire process. Judging from the uniformity of the 18,000 1 by 1 mm Vertical LED on Metal Alloy chips from one single wafer, we can clearly see the yield advantage of this larger wafer MOCVD process. One of the contributing factors to yield enhancement is the significantly reduced edge area compared to the area equivalent of nine 2-inch wafers.”

Dr. Christian Geng, general manager Greater China of AIXTRON, said, “The process obviously works from A to Z. I expect that once the price of a 6-inch substrate becomes competitive many of our customers will convert their AIX 2800G4 HT systems from 42 by 2-inch to 6 by 6-inch configuration since it merely requires the exchange of the so-called Satellite Disks.”

C-Series Solid-State High-Bay Luminaire Breaks the $50 per Kilo-Lumen Price Barrier at 79 Lumens per Watt
Albeo’s C-Series High-Bay has surpassed the next critical step in price and performance for large scale industrial-commercial deployment. ITL Laboratory independently verified to LM-79 standards Albeo’s HB-B644-011C0-R5 performance: 25,650 lumens with an efficacy of 78.8 lm/W and power factor of 0.99 at 5,000 K CCT. The C-Series High-Bay has won both the DOE’s 2008 NGL “market ready” award and Colorado’s “2008 Sustainable Medal of Honor” award. Priced at better than $50 per kilo-lumen in quantities of 250 units or greater, the combined energy and maintenance savings enable customers to achieve pay-back in 1 to 3 years.

The C-Series white-LED general lighting platform is available in linear, dual linear, low bay and high-bay configurations. Options include motion sensors, focusing and “batwing” optics, 120/240/270 VAC inputs, and 3K/4K/5K/6K color temperatures with CRIs ranging from 75 to 92. Applications include warehouses, garages, schools, manufacturing facilities, big-box retail outlets, cold-storage facilities, and other general lighting.

Built for reliability and lifetime, the C-Series High-Bay, combines toroidal transformers (the most reliable power conversion technology) with Albeo’s TEMPR thermal management system to minimize LED junction temperature and maximize lifetime, light output and efficiency. “Our best-in-class thermal, mechanical, electrical, and optical designs allow us to deliver well over 25,000 lumens with an efficacy of nearly 80 lm/W,” said Paul Winker, Product Line manager, Albeo Technologies. “Putting fluorescent or high intensity discharge bulbs in hard to reach places is unproductive now that our LED High-Bay fixture can outperform them.”

Universities Join Cree LED University Program
Cree, Inc. has announced that the University of Miami and the University of Alaska Anchorage have joined the LED University program.

The University of Miami is installing new LED pole lights to improve walkway illumination on the main campus and retrofitting LED lighting at various interior locations.

Twenty BetaLED LEDway fixtures now illuminate walkways on the main campus in Coral Gables, providing much-improved visibility and safety. In addition, the university is evaluating LED lighting for interior applications such as conference rooms, hallways and classrooms. LED lighting pilot installations are saving as much as 70 percent on energy used for lighting conference rooms and hallways.

UAA began converting lighting applications to LEDs five years ago, starting with signage, specialty lighting, aisle lighting in lecture halls and theater stairway lighting. The university recently completed a parking lot pilot with seven fixtures from BetaLED, and is evaluating 14 BetaLED(TM) fixtures for parking garages and covered walkways. UAA is reducing its energy consumption for the parking lot and garage by approximately 60 percent, as compared with the high-intensity discharge (HID) lights that were replaced. The university is also evaluating LED lighting for recessed lighting in stairwells and mechanical rooms, walkway bollards and parking lot lights for the new Health Science Building.

"Today we are celebrating Earth Day at UAA and we're excited about expanding our LED installations for even greater energy and maintenance cost savings," said Chris Turletes, UAA vice chancellor, facilities and campus services.
"We're achieving better visibility and significant energy savings, and anticipate significantly reduced maintenance costs for the life of the LED fixtures, which can be 25 years. We are standardizing on LED lighting in the applications where we can achieve these dramatic benefits."

"Lighting at UAA is a major focus for visibility and safety, especially during Anchorage's long winter nights," said Deb Lovig, LED programs manager at Cree. "UAA joins a prestigious group of progressive institutions that are promoting and deploying LED lighting as each works toward increasing energy savings, protecting the environment, reducing maintenance costs and providing better light quality."

ilumisys Partners with National Center for Manufacturing Sciences for Department of Energy Solid-State Lighting Program
ilumisys, Inc., developer and producer of next-generation solid-state lighting technology, has entered a partnership with the National Center for Manufacturing Sciences (NCMS) in conjunction with a Department of Energy grant for product life cycle design for solid-state lighting.

The purpose of the DOE grant of more than $590,000 to the National Center for Manufacturing Sciences is to develop a sustainable design and manufacturing strategy that addresses product use, recycling and disposal scenarios for LED-based lighting.

“NCMS has been successfully commercializing and standardizing innovative technology for decades,” said Rick Jarman, president and CEO of NCMS. “This partnership with ilumisys will strengthen the growing solid-state lighting industry both in Michigan and nationwide.”

In conjunction with ilumisys, NCMS plans to build collaborations for applied research and development activities involving the implementation of sustainable design practices into LED lighting products. Support activities include program technical and management services, including leveraging other programs within the DOE to complement existing efforts.

“Many companies are beginning to design and manufacture solid-state lighting, but there is no acknowledged set of best practices for lamp and luminaire design,” said Dave Simon, president of ilumisys. “This partnership, which addresses not just the complete end-use product but also the recycling and disposal issues, is a huge step for LED lighting.”

“We are going to take a very systems-level approach to help guide product decisions such as material selection, fastening methods, and manufacturing methods to help ensure that finished products using LED technology have a truly beneficial effect on carbon footprint and other environmental issues,” Simon added.

In addition to providing an energy efficient alternative, the ilumisys products are mercury-free. The 500 million to 600 million fluorescent tubes discarded annually in the United States introduce an estimated two to four tons of mercury to the environment, despite industry and government efforts to limit mercury content and encourage recycling.

ilumisys, formed in 2007, is a spinoff of Altair, a global software and technology company that has a growing presence in the energy market. With the backing of Altair, its majority owner, ilumisys has a deep and substantial investment in research and development that includes more than 30 patent applications filed to date.
