Product News I Sub-Assemblies Sharp presents new 10W LED arrays
Sharp has unveiled a new range of 10W LED arrays based on recent technical advances made in LED production, which have improved the efficiency by up to 47%. This second generation of 10W arrays has four distinguishing features according to the company: they are compact, lightweight, economical and significantly brighter than before. Sharp has retained the dimensions of 15 x 12 x 1.6 millimetres unchanged, along with an aluminium ceramic plate as carrier material. The flat surface of the ceramic plate and the soldering points already in place make it possible to attach the modules to a suitable heat sink, without too much effort or additional connecting material, thereby achieving efficient heat dissipation.
Depending on the module, the new types
offer a light output of up to 900 lumens, a luminous efficacy of up to 106 lm/W in standard operation, high CRI values of 82 and a long service life of 40,000 operating hours at an operating temperature of up to 90°C. The new generation is specified for use with a forward voltage of 17.7 V and a forward current of 480 mA. But the arrays can also be operated using a current of up to 800 mA, whereby values of up to 1300 lm can be reached. With the shades
"Natural White", "Warm White", and "Pure White", the colour
temperatures of the new white light LED arrays are in the range of 3,000 to 5,000 Kelvin. The
extensive range of LED
lighting arrays allows Sharp to provide numerous marketable solutions for the use of LEDs as light sources for lamps and lighting fixtures. The luminous Mini Zeni LED modules from Sharp are suitable for numerous applications, e.g. spot lighting and for use in LED retrofit lamps, etc. Initial samples are available in the colour temperatures of 3000 and 4000K and they can now be ordered from Sharp and distribution partners across Europe.

Next generation of lighting-class LEDs from Cree
Cree has introduced the XLamp XB-D LED, the first LED based on an innovative new technology platform. According to the company the XLamp XB-D LED will help to usher in a new era of price-performance for lighting-class LEDs. This LED can help to simplify designs, ultimately removing a key barrier to widespread LED implementation - the up-front system cost. The XB-D LED is capable of delivering twice the lumens-per-dollar of other LEDs, and offers the industry’s smallest lighting-class footprint of 2.5 mm x 2.5 mm. The XB-D LED is 48 percent smaller than the XLamp XP package and is suitable for lighting applications where high lumen density and compact light sources are required. The innovations behind this next generation of lighting-class LEDs can enable significantly lower prices for LED lighting products by using up to three times fewer LEDs, three times fewer optics and substantially smaller circuit boards than current designs. According to Mike Watson, Cree senior
director of marketing, LED components, “With this new platform Cree has fundamentally redefined the price-performance paradigm for our components customers. It’s not enough to
just
make LEDs brighter - it’s also about improving product
payback and market acceptance of LED lighting.”
Leveraging Cree’s proven silicon carbide technology, the XB-D LED delivers up to 139 lumens and 136 lumens per watt in cool white (6000K) or up to 107 lumens and 105 lumens per watt in warm white (3000K), both at 350 mA and 85°C.
These XB-D LEDs are also compatible with most existing XP family secondary optics, which can speed the optical design process and create direct cost savings for existing XP family-based designs.

www.cree.com EBV launches light laboratory to aid customers analysing their lighting projects
EBV Elektronik has become one of the first companies in the European semiconductor distribution industry to offer its customers access to a light laboratory. The facility will enable them to perform all the relevant photometric and radiometric light measurements in accordance with specifications from the Commission Internationale de l'Eclairage, the international commission on light. From using spectroradiometers and goniophotometers to thermal imagers, the complete spectrum of
products from individual LEDs right up to the complete luminaires are covered by the EBVLightLab.
Many luminaire manufacturers are looking to
move from conventional filament and (C)FL lamps to LED lighting, but don’t have the necessary design expertise nor the expensive measuring equipment, according to EBV. As a result, starting in February 2012, EBV
Elektronik will offer its customers a new service at its headquarters in Poing, near Munich. The new
E-tec
light laboratory known as EBVLightLab will allow customers to perform radiometric and photometric measurements across the entire light chain: from measurements on individual LEDs or LED modules and comparative measurements of light sources (e.g. light bulbs versus CFL or LED solutions) right up to the complete measurement of entire luminaires. This will give even smaller companies access to exclusive, high-precision measuring technology.
EBV will also hold training and customer
seminars in the new EBVLightLab. In these seminars, EBV will discuss the differences, advantages and disadvantages of the various light sources and give tips on optimum implementation of luminaires adapted to the relevant application. The LightLab has already proven its worth in training the company’s own FAE team. In the medium term, EBV also intends to develop dedicated reference designs for LED lighting.
