168 TECHNOLOGY / ANNUAL LED ROUND UP
able versions: 4W; 6W, 7W, 9W, 12W and 15W); 15 x 12mm COB (ceramic substrate), particularly suitable for retrofit bulb and spotlight applications. The mini Zenigata uses a unique ceramic substrate for long- term reliability and low thermal resistance for efficient thermal management. Series main features include: • Chip-on-board LED with only two termi nal connections for easy installation;

• CRI options of Ra 80+ and 90+; • Luminous flux (typ.) from 410 lm to 1400lm;
• Luminous efficacy of up to 100lm/W; • Colour variation within a 3 MacAdam ellipse;
• Dimensions: 15 x 12mm; • Standard 10mm LES and ceramic sub strate in all wattage classes;
• Long lifetime: >40,000 hrs depending on operating conditions*;

flux Artist Series product and is designed for applications that require perfect halo- gen-level colour rendering and smooth, continuous dimming to 0.1% (power). The XLM 3000 Artist combines high flux with high colour rendering and is suitable for track, recessed downlight, and wall wash luminaires. As with the rest of the Artist Series Range, colour rendering is accurate across all 15 CIE standard test colours, both pastel and saturated, including the deep red and skin tone references. Ra = 90+ and 95 typical, outperforming other LED solutions, as well as compact fluorescent and compact metal halide sources. XLM Artist Series is available in Correlated Colour Temperatures (CCTs) of 3000K, 3500K, and 4000K. As with all Xicato’s LED modules, the XLM 3000 Artist is colour consistent initially (1 x 2 SDCM) and over life and maintains its light level over time (L70/B50/50,000hrs) Xicato’s new ‘point’ module, shown in figure 18, addresses one of the last bastions of halogen accent lighting - extremely tight beams, with very high luminous intensities (such as from AR111 lamps). With an aper- ture of only 6mm, the new high-luminance XPM enables reflector designs with peak intensities from 7,000cd to 50,000cd, and beam angles of 10° to 3.5°. The new XPM is offered in both 2700K and 3000K CCT. CRI (Ra) is 80 minimum as is CQS (Colour Quality Scale).
MAY 2012 LED Engin: launched ViviLux (figure 19), a family of high-efficiency single-emitters

• Operating temperature range: -30° to +100°C;
• Four colour temperature options.
combined with secondary total internal reflection (TIR) lenses delivering high Lux- on-Target, high CRI and 2 MacAdam Ellipse consistency for directional lighting. It is an extreme power density and high-efficiency solution for retail and commercial light- ing comprisingsingle-package emitter and secondary lens. The powerful, yet compact emitter and lens combinations produce up to twice the centre-beam lux of array-based LEDs with comparable power and reflector optics and lead the industry in terms of ‘lux efficacy’. Under steady-state conditions at 80ºC ambient, ViviLux emitters have luminous efficacy of 85lm/W at 350mA and 1700lm at 700mA. With a CRI of 90 and minimum R9 of 70, ViviLux ensures accurate colour rendition in even the most demanding applications. Furthermore, emitter-to-emitter variations of less than 2 MacAdam Ellipses guaran- tee lighting consistency, both initially and throughout the service life of the emit- ters. ViviLux, which is based on LED Engin’s proven LuxiGen emitter technology, is avail- able in three beam options: 24°/ 35°/45°, providing flexibility and freedom in lighting design. Nichia: released the NVSx219B. This is the second generation of the 219 which offers 290 lumens or 132lm/W at its typical 700mA drive current. This point source, ceramic 3.5x3.5 package is a great fit for a variety of applications calling on a power LED with excellent durability and lifetime Sharp: launched the Mini ZENIGATA line up which includes LEDs between 4 – 15W (avail-
Soraa: launched its VIVID LED MR16 lamp - the first full spectrum LED MR16 lamp with colour quality and rendering superior to both traditional halogen and competi- tor LED lamps with the highest output 95 CRI. With rich saturated colour rendering, and excellent colour stability, Soraa’s VIVID LED MR16 lamp is the lamp of choice for demanding display applications. The VIVID MR16 lamp offers superior light quality, while being 75% more energy efficient than comparable halogen lamps. It is designed to replace standard 40 to 50W MR16 halogen lamps and is available in 2700K and 3000K correlated colour temperatures.
JUNE 2012 Bridgelux & Toshiba: announced that they had achieved the industry’s top class 8” GaN on Silicon LED chip emitting 614mW, <3.1V@350mA in a 1.1mm square chip, just months after they engaged in a joint col- laborative agreement (figure 20). Toshiba Corporation announced that from October 2012 it would start mass produc- tion of white LED on a production line that the company will construct in the 200mm wafer facility at Kaga Toshiba Electronics Corporation, a production base for discrete products in northern Japan. A combination of Bridgelux’s crystal growth and LED chip structure and Toshiba’s ad- vanced silicon process and manufacturing technology were credited with enabling this mass production of high brightness white LEDs. Luminus Devices: announced it had optimised RGB projection chip brightness
