LED Engin's new 7mm LED emitter boosts output by 250% to 1300 lumens
LED Engin has launched the LZ9 LuxiGen emitter, a new family of devices that deliver 2.5 times the lumens of existing LZ4 products within the same 7mm x 7mm footprint. The LZ9 emitter more than doubles the Lux on Target, making it suited for directional lighting fixtures such as the spot, accent and downlighting used in retail and commercial applications. LED Engin also offers a family of secondary total internal reflection (TIR) lenses in Spot, Narrow Flood and Flood beams compatible with the new LZ9-series. The LuxiGen single emitter/ single lens combination, available in colour temperatures ranging from 2700K Warm White to 6500K Cool White, provides the equivalent performance of a 75W PAR20 or PAR30 halogen source. In addition to the standard CRI 80 product, the LZ9-series is the first LuxiGen series to be introduced with a CRI 90 option for applications that demand the highest levels of colour rendering. CCT binning of 3 MacAdam Ellipses is also available as a standard option for uniform colour emitter to emitter. With 1350 lumens at 3000K and 1600 lumens at 6500K colour temperatures, the LZ9
emitter incorporates 9 die in a compact, 3 x 3 series-parallel configuration, package and, like the rest of the LuxiGen platform, uses a patented multi-layer ceramic substrate engineered to minimise stress on the die. The substrate has low thermal resistance to lower the junction temperature of the die for consistent performance over the service life of the product. The LZ9 emitter and TIR lens combination leads the industry in terms of 'lux efficacy' or lux/Watt performance, a term that is more accurate than lumens/Watt to describe the usable light delivered in downlighting applications.

Notebook and All-in-One PCs set to drive touch screen growth
Notebook and all-in-one PCs are helping to drive total touch screen module revenue with the market set to be worth $16 billion in 2012, and the doubling to $31.9 billion by 2018, according to new research from the NPD DisplaySearch. Touch screens used in small/medium sized devices, such as smart phones and tablet PCs, are all also helping to grow the overall market. Tablet PCs are the fastest growing application for touch, with 2011 shipments tripling to 79.6 million units. Growth continues to be strong, and NPD DisplaySearch expects that more than 130 million touch screens will be shipped for tablet PCs in 2012, and over 190 million in 2013. Revenues for touch screens in tablet PCs are expected to grow by more than $3 billion in 2013.
“Over the next few years, demand for thin, lightweight, and lower-cost touch devices will drive strong touch screen growth in display applications,” noted Jennifer Colegrove, PhD, Vice President of Emerging Display Technologies at NPD DisplaySearch. Touch penetration is forecast to increase dramatically in larger size (>10”) devices, such as convertible/hybrid notebook PCs. A number of Ultrabook mobile PCs (promoted by Intel) will adopt touch screens by the end of this year and , in addition, Microsoft Windows 8 has touch functionality designed in. Its release, scheduled for release later this year, is expected to accelerate touch screen adoption in PCs.
Low-watt LEDs set size and efficiency benchmark
Marl International, the UK distributor for Citizen discrete LED components, has launched its new low wattage LED range which combines an ultra-compact size with enhanced levels of efficiency and uniformity for linear and other array applications.
The new range includes the 0.06W CLL801, the 0.1W CLL611 and the 0.2W CLL130 series LED die, offered for assembly as LED-on-Board devices. All three families are suitable for use in arrays where low heat output and exceptional uniformity of brightness are required. Marl is able to supply the die as discrete components, or offer them fully assembled on PCB’s or aluminium clad boards to meet individual

According to NPD DisplaySearch the touch screen penetration rate in notebook PCs is set to jump fourfold, from 2% in 2011 to approximately 8% in 2013.
Over the next few years, adoption by all-in- one PCs and automobile monitors are expected to be leading contributors to touch screen market growth. Touch technologies with high transmittance, low power consumption, multi- touch, or gesture recognition will benefit the most from these applications.
Touch technology evolving Projected capacitive growth has been explosive since being popularized by Apple in 2007, and many tablet PCs manufacturers have adopted it. This technology became the top touch solution in 2010 in terms of revenue. Due to the pressure to reduce cost and materials, conventional add- on type projected capacitive touch is evolving in three directions: sensor-on-cover, on-cell, and in- cell.
Supply of sensor-on-cover (SOC) touch technology is rapidly ramping up, with more than 20 suppliers in 2012. Shipments of SOC touch modules are expected to grow more than seven-fold from 2011 to 2013, and revenues are forecast to surpass $2.8 billion in 2013. NPD DisplaySearch forecasts that SOC will surpass add-on type projected capacitive touch and become the leading touch technology in 2015 in terms of revenue.
electrical and environmental protection requirements.
Believed to be one of the most compact
discrete LED devices currently on the market, the Citizen 0.06W CLL801 is just 1.6mm x 0.8mm x 0.9mm, but despite its size can deliver up to 6.5 lumens from a forward current of 20mA at 3.2V, giving an efficiency of up to 102 lumens per watt for the 5000K colour temperature Ra80 device. Colour temperatures of 4000K, 3500K, 3000K and 2700K are also available and a 6500K version is planned. Marl is also abler to offer the Citizen 0.1W CLL611 and the 0.2W CLL130 series LED die, with the same range of colour temperatures as the CLL801 above. Aimed at linear fluorescent light replacements, the 0.2W LED die offers efficiency up to 139 lumens per Watt from a package of just 2.0mm x 1.6mm x 0.75mm. The 0.1W device is slightly smaller, at 2.0mm x 0.8mm x 0.9mm and offers an efficiency of up to 127 lumens per Watt.
