Solid-State Lighting 2015
By Dan Jacobs, Product Engineer • OPTEK Technology

The lighting industry is in a state of flux. Change will mean obsolescence for many lighting technologies of today, including the majority of solutions currently being developed that use today’s best LEDs. Current state-of-the-art solid-state lighting will be insufficient for future demands. Rather than look at LEDs as a technology that need not be replaced, today’s designers must consider that aspects of these products will certainly be outmoded tomorrow, particularly the LEDs themselves. The components and solutions from 2003 are no longer efficient or innovative enough. It will be no less true for 2009 products in 2015. The changing criteria for LED lighting will greatly impact the implementation of LEDs in the next decade.

Case Study: Tokyo Park Lighting
Legendary Cherry Blossoms Shine LED-Bright with Assistance from Future Lighting Solutions
Every spring, hundreds of thousands of Tokyo residents flock to Chidorigafuchi Park to witness more than 200 cherry trees exploding with baby pink blossoms. For years, the trees were illuminated at night with halogen lamps that not only consumed excessive energy but also damaged the flowers with heat and ultraviolet rays. In 2009, many of the existing lights were replaced with more energy-efficient, flower-friendly solid-state floodlights built with Luxeon K2 with TFFC (Thin Film Flip Chip) LEDs from Philips Lumileds. Nagasaki-based lighting manufacturer INEX Corp. developed the new LED luminaires with engineering support from Luxeon supplier Future Lighting Solutions, reducing energy use and carbon emissions by more than 90 percent while simultaneously advancing Tokyo’s efforts to become a low-carbon city.

‘Sakura’ Season
The Japanese custom of viewing cherry blossoms, known locally as sakura, dates back to before the eighth century. Sakura bloom all over Japan from mid-January to early May, typically flowering in Tokyo in late March or early April. Visitors to Chidorigafuchi Park during the one or two week-long cherry blossom season are treated to vast expanses of flowering trees that can be seen from land as well as from boats traversing the moat that used to be part of the Imperial Palace grounds.

Lighting the trees at night is essential to support the tradition of after-dark flower viewing parties as well as to take full advantage of the short-lived season, but the existing halogen lighting failed to fit with energy-saving initiatives launched by Tokyo governor Shintaro Ishihara to conserve natural resources and fight global warming. When park officials decided to climb on the ‘green’ bandwagon by switching to LED floodlights, they were unable to find an off -the-shelf product that met their requirements. That’s when they turned to INEX.

Building a Better Floodlight
The park needed several different outdoor solid-state luminaires with light outputs as high as 2,800 lumens. Fixtures would be placed either on the ground or on a stone wall to light the trees from below. INEX developed the basic board design but sought outside expertise on several engineering issues related to thermal management. The company also wanted to explore their LED product options because of dissatisfaction over color inconsistencies in a previous project that utilized non-Luxeon light sources.

“We knew we had to drive whatever LED we chose at a high current to hit the park’s target brightness levels, but we didn’t have time for extensive prototyping. We also needed to find an LED that would support that level of current and a way to ensure color consistency from LED to LED,” said Youichi Oda, president of INEX. “Future had the tools, expertise and narrow color bin selection to help.”

Future engineers solved the prototyping problem with Future’s proprietary QLED thermal simulation software, enabling rapid modeling of heat distribution as well as luminous flux without lengthy trial-and-error design cycles. Future also recommended the use of Luxeon K2 with TFFC LEDs because of their ability to be driven at 1,000 mA and thereby produce the required light output.

The color challenge was addressed with Future’s binning program, which offers 19 color bins for cool white Luxeon LEDs to ensure color uniformity within each shipment as well as from order to order. Future was able to guarantee a supply of LEDs from several cool white color bins that met the project’s specific requirements, giving INEX assurance that the color of their new floodlights would not vary perceptibly.

90 Percent Energy Savings
In early 2009, the collaboration between the two companies culminated in INEX’s SKY HIGHBEAM-X, a family of floodlights that utilizes Luxeon K2 with TFFC LEDs along with custom-designed heat sinks, optics and drivers. The fixtures are available in both 7- and 14-LED models, with special weatherproofing measures devised to protect the fixtures from rain and dust.

The finished floodlights were installed in Chidorigafuchi Park between March 27 and April 10 to coincide with the annual cherry blossom festival.

The fixtures are illuminated for 4.5 hours every night during the annual hanami (flower viewing) season.
The transition to solid-state lighting is saving the park an estimated 90 percent in energy usage and related costs for each replaced fixture, shrinking per-unit consumption from 150 to 15 kilowatt-hours. It is also reducing carbon dioxide emissions for all floodlights involved in the replacement program from 4.2 to 0.2 metric tons during the cherry blossom festival alone, helping the park do its part to combat global climate change.

In addition, moving from halogen to LED floodlights with a far cooler beam and lower UV levels will help keep the cherry blossoms in peak bloom for as long as possible, maximizing park usage as well as the viewing pleasure of local residents. Saving energy and saving the flowers: that’s a big return on the park’s LED lighting investment.

At the same time, the SKY HIGHBEAM-X has become a staple of the INEX product line, offering high performance and an expected 40,000-hour or longer bulb life along with a low carbon footprint. The development work was inspired by cherry blossoms, but for INEX it is destined to bear fruit over and over – like the cherry trees themselves.

The reception building of Osram Opto Semiconductors in Regensburg (Germany).

Reception Building Lit Entirely with LED Technology
The newly constructed reception building at Osram Opto Semiconductors’ head office in Regensburg (Germany) showcases the various lighting capabilities of LEDs. All areas of the building, including the workspace, visitor’s area, decorative effects and outdoor lighting are lit using LEDs. In contrast to conventional solutions, LEDs make innovative lighting designs possible while being energy efficient too, as the used white LEDs save up to 35 percent energy.

Osram Opto Semiconductors’ reception building is one of the first buildings in Germany to be lit inside and out exclusively by LED technology. More than 4,500 white and colored LEDs provide the accent and general lighting throughout the entire structure. New LED systems were used as they offer designers an array of color options with a high light output. The slim packaging saves space and provides unlimited versatility in application options.

The wall of light provides all the lighting for the visitor area. With various lighting scenarios the 17 by 17 meter area produces various degrees of brightness and moods.

The reception building showcases Osram Opto Semiconductors every-day LED applications and is especially unique as the building has almost no visible lamps or light switches. Exemplified is how white and colored LEDs are not only able to create a special atmosphere via accent and effects lighting, but also how LEDs illuminate rooms and workspaces in an energy-efficient way.

35 Percent Energy Saving
Many of the LEDs used in the reception area are dimmable, the brightness can be adjusted between five and 100 percent, enabling people to regulate the light used. Also in effort to preserve energy, occupancy and daylight sensors were installed in the restrooms to ensure light is not used when not necessary.  With these energy-saving methods, in addition to the overall energy-efficiency of LEDs, a savings of 35 percent with white LED lighting is achieved compared to traditional lighting solutions. Another advantage of LEDs is that with a life of more than 50,000 hours they are extremely durable and virtually maintenance-free.

Workspaces can also be lit ergonomically with LEDs, by backlighting monitors, for example. Apart from this, color LEDs can also achieve interesting effects, as shown here on the screen.

Design Versatility
The design versatility of LED applications enables the absence of ceiling lights in the visitor reception area. Instead, a 17 by 17 meter wall of light, consisting of a highly elastic and translucent foil, 0.4 mm thick, provides the space with variable light options. In the panel’s frame there are LED strips (LI-EX profiles), which emit light sideways, parallel to the wall. The profiles of luminaire manufacturer LI-EX on the upper and

lower screen frames are fitted with warm and cold white Golden Dragon Plus LEDs, the profiles on the right and left with colored Golden Dragon RGB LEDs. This innovative design dynamically lights the wall using a full color scale, including warm to cool white light, through moving color transitions. The transitions are controlled using Traxon’s touch-wheel.

Red, green and blue LED strips were installed behind a 4 by 4 meter glass area of the visitor counter for a decorative display. Behind the counter the LEDs backlight the workspace to provide the room with an ergonomic and fatigue-free working environment. White Power TopLEDs were used for the mirror and ceiling lighting in the restrooms, as well as for accent lighting on door frames. Outside LEDs illuminate the pathway and handrail.

“Illuminating the building with LEDs all-round proves that the LED technology has left its niche,” said Artur Grösbrink, project manager at Osram Opto Semiconductors. “The technology can be used in any area of professional lighting and is also eminently suited for showcasing rooms and buildings. Decorative effects are just as feasible as stimulating workspace or atmospheric room lighting.”

Enfis Introduces the Innovate Series of Ultra-Bright White LED Arrays

As are all Enfis LED products, the Innovate series of LED arrays are fully compliant with the EU’s RoHS Directive restricting hazardous substances.

White LED Driver with Dynamic Backlight Control Reduces Power Consumption of Portable Displays
National Semiconductor Corp. has introduced a small white LED driver with dynamic display backlight control. The LM3530, a member of National's PowerWise  energy-efficient product family, drives up to 11 high-current LEDs in series, illuminating larger displays in portable media devices such as smartphones. The LM3530 is offered in a 12-bump micro SMD package measuring 1.615 mm by 1.215 mm by 0.425 mm.

Today's increased multimedia content in portable devices is fueling the trend towards larger displays and longer video playback, which require more power. National's LM3530 LED driver employs sophisticated ambient light-sensing algorithms and content-adjustable backlighting to optimize the display, realizing up to a 55 percent power saving over the common practice of driving the backlight at a constant brightness.
In a pair of tests, National compared the energy consumption of a backlight illuminating a 3.5 inch iPod touch display with and without National's LM3530 LED driver.

The evaluation was conducted using typical multimedia downloadable material, in this case an episode from a television series and a trailer from a popular movie. Results showed the LM3530 achieved a power savings of 43 percent and 55 percent, respectively, over traditional backlighting. The predominately darker picture in the movie trailer garnered further power savings because the backlight was reduced more frequently for dark images.

National's LM3530 current-mode boost converter can supply up to 29.5 mA of power to 11 white LEDs from a single-cell Lithium-Ion battery. A wide degree of programmability via an I2C compatible interface enables the designer to adjust for lighting effects such as fading, external ambient conditions and lighting level, as well as brightness and image performance.
The LM3530's programmable ambient light response along with a separate pulse-width modulation (PWM) dimming input enable the backlight LED driver to intelligently determine lighting requirements and select between various dimming options, optimizing the light output for the given conditions. Logarithm and linear LED brightness mapping provides flicker-free dimming. A fixed-frequency, 500 kHz boost converter provides high efficiency over the LED current range.

The LM3530 brings power savings to the serial implementation of large display backlighting. For parallel charge pumps, National will offer a product with a similar feature set in October 2009.

Available now, National's LM3530 is priced at $1.99 in 1,000-unit quantities.

Nexxus Releases New LED Lamp Line with True Dimming Capabilities
Nexxus Lighting has introducedArray, the new LED lamp line with true dimming capabilities.

Luxeon Rebel Hot/Cold Factor Improves Solid State Lighting Efficiency and Simplifies Thermal Design
Philips Lumileds recent breakthrough implemented in the latest Luxeon Rebel LEDs for illumination applications improves efficacy and light output performance at luminaire operating temperatures. Hot / Cold Factor compares the light output of the LED at 100°C Tj and at 25°C Tj, which is how LEDs are specified on a datasheet. LEDs in a luminaire are operated at very high junction temperatures, often between 80°C and 110°C. As temperature increases, light output and efficacy decrease. With a Hot / Cold Factor of 0.93, the Luxeon Rebel LEDs deliver more light and improved efficacy. Typical Hot / Cold Factors range from 0.80 to 0.85 at junction temperatures of 100°C. Maximizing this factor is critical as companies design solid-state lighting solutions that are intended to meet Energy Star requirements.

“Hot / Cold Factor is one of the clear differentiators between LEDs,” said Rudi Hechfellner, director of Technical Solutions.  “A high HC Factor can simplify the thermal system design and lower the cost per lumen in the final application.”

Hot / Cold Factor charts for all LUXEON Rebel LEDs are available from the datasheets published at www.philipslumileds.com.

Luxeon Rebel Becomes First ‘UL Recognized’ DC Power LED, Simplifying UL Certification and Speeding Time to Market for New Solid State Lighting
Faster, simpler listing of new solid state lighting applications by Underwriters Laboratories (UL) has just become a reality with UL recognition of Philips Lumileds’ Luxeon Rebel LEDs – the first high power DC LEDs to earn UL Recognized certification. The recognition will speed time to market by making it possible to obtain UL Listed status for new luminaires built with Luxeon Rebel without requiring a full in-system LED component investigation. The certification will also facilitate Energy Star acceptance, since luminaires must be UL Listed in order to be eligible for the Energy Star label.

In addition, being UL Recognized will help bring increased efficiency to LED applications, such as street lights, by facilitating the use of Class 1 power supplies.  The Luxeon Rebel lens meets the requirements to be considered an electrical enclosure under UL standards, eliminating the need for a full UL investigation that in the past has discouraged the use of more efficient Class 1 power sources.

UL approval is a de facto requirement for lighting products in the US because it is required by key parties including municipalities, government agencies, architects and insurance companies.

“Most solid state lighting manufacturers that sell products in the US require UL listing. Until now, the process has been very confusing,” said Rudi Hechfellner, director of Applications at Philips Lumileds.  “By using Luxeon Rebel, engineers can rely on clear direction from UL, shorten UL review cycles, and avoid unexpected issues that might arise in the luminaire certification process.”

Luxeon Rebel LEDs can now be found in UL’s Online Certifications Directory.  They are compliant with UL OOI 8750, the interim standard for certifying LED light sources for use in lighting products.  More information can be found at http://ulstandardsinfonet.ul.com/outscope/outscope.asp?fn=8750.html.
