3.45mm). GE Lighting: launched the high lumen Infusion M4500 Series (figure 25) as a new addition to its innovative range of Infusion LED modules. When combined with high efficiency optics, it allows for a genuine replacement of 50W and 70W HID with a true replication of performance and light output. The Infusion M4500 Series plays a key role as it delivers the highest lumen package of all the products within the Infu- sion range up to 4500 lumens using a 50W module. Further benefits include varying colour temperatures which include: 2700K, 3000K and 4000K, in addition to >80 and >90 CRI options.
OCTOBER 2012 Cree: announced commercial availability of XLamp XB-D color LEDs and XLamp XM-L multi-colour LEDs. The high-performance colour LEDs provide lighting manufacturers with discrete and multi-colour LED options to more cost-effectively address a wider spectrum of applications such as architec- tural, vehicle and display lighting. XLamp XB-D colour LEDs deliver up to 1416mW for royal blue, 92 lumens for blue, 198 lumens for green, 210 lumens for red and 261 lumens for red-orange, all at 1A in the 2.45mm x 2.45mm footprint. XLamp XM-L colour LEDs deliver up to 89 lumens for royal blue, 214 lumens for green, 229 lumens for red and 272 lumens for white at 1A in the 5mm x 5mm footprint. Cree also joined the LED array fraternity by introducing its CXA LED arrays that deliver system-level performance ranging from 500 to 5000 lumens and up to 146 LEDlm/W, enabling applications ranging from LED replacement lamps to commercial down- lights. For example, the CXA1512 LED array can deliver over 1900 lumens at 120lm/W in a very small 9mm optical source size. Other LED arrays may come close to this level of performance, but not in this small a form factor. The CXA1512’s small size is critical for enabling low system cost in a wide range of lighting applications, from narrow-beam spotlights to wide-area lights. GE Lighting: introduced the Infusion Narrow

Punch Modular (NPM) system (figure 26) a new LED light source which, when combined with GE’s new innovative optical system, creates a narrow light beam angle for track mounted, recessed accent lighting and spot- lighting. When run at its maximum power of 25W, the Infusion NPM system delivers a peak intensity of up to 30,000 candela, in a narrow 10 degree beam of high quality light. Osram: The Duris E5 from Osram provides the perfect LED for homogenous distribu- tion of light in panel lights. With a colour temperature of 4000K and a CRI of 85, the LEDs generate a light colour which is similar to daylight – an aspect which is particularly important in office and retail lighting. The Duris E5 are among the most efficient LEDs on the market in their performance class (mid-power), achieving 110lm/W (at 4000K and 120mA). Philips Lumileds: introduced the Luxeon Rebel Plus, delivering a 15 percent perfor- mance upgrade over earlier versions of the product. Designed with an industry-stan- dard 4530 package and a 2.55mm dome, the Rebel Plus is optimised for maximum light output and is available in a range of CCTs from 2700K-5000K
NOVEMBER 2012 PhotonStar: previewed their ‘Pastel’ ver- sion of the technology due for release in 2013. This uses the same active feedback technology as the other ChromaWhite ver- sions providing high CRI over Ra90 whilst on planckian, but offers pastel colour possibili- ties as well. Sharp: introduced the new Tiger ZENIGATA LED array which is the first tuneable-white

high power chip-on-board (COB) LED, having four terminal connections for easy installation. The Tiger LED array offers the ability to tune along the blackbody curve from 2700K to 5700K whilst maintaining a 2,000lm output. With a circular light-emit- ting surface (LES) having a diameter of 17mm it is possible to provide simultaneous emission of warm and cold white light to achieve natural white. It offers a CRI of up to 92 in cold white and up to 94 in warm white tones with a typical luminous flux of 2,000lm and typical lumi- nous efficacy of 83lm/W in just 25W and a 24 x 20 x 1.8mm package. The Tiger array provides high-quality light across the entire colour temperature spec- trum and from a single point light source with no multiple shadows, no colour shad- ows and no differences in colour. The tuneable white LED works by combining warm white and cool white multi-chip LEDs within a single COB solution, creating a ti- ger-stripe appearance as shown in figure 27. A two-channel driver can be used to drive the two colours independently, allowing smooth tuning from warm white (2700K) to cool white (5700K) by varying their relative drive current. It is possible to tune through this entire range while maintaining a lumen output of 2,000lm.

Final Observations from the industry What to expect in 2013... Paul Scheidt, Product Marketing Manager, Cree, LED Components believes: “In the next year, the lighting industry is going to realise that LEDs aren’t just the ideal light source for certain niche applica- tions, but they can be the ideal light source for all lighting applications. As an LED com- pany, we have been saying this for years, but 2013 will be the year that the message is finally accepted. 2013 will be the year that the general public becomes much more aware of the benefits of LED lighting. People know LEDs in the context of Christmas lights, TVs and refrigerators. Now LEDs are starting to light up their roads, their stores, and even a few of their homes. Better LED lighting products
