driver is required. No extra costs, no addi- tional installation time and space needed. (Fig 8) Seoul Semiconductor: announces the new MJT 4040 package using Multi Junc- tion Technology to bring performance and size advantages to the LED outdoor and streetlight markets. The MJT 4040 uses multi-junction technology that allows multiple LED junctions to be combined in a single chip thereby increasing the operating voltage and concentrating more light output within a given area. Operating at a nominal 64 Volts and 20mA, the device can reach output levels of 200 lumens and efficacies as high as 140lm/Watt (5000K CCT). Street- lights using the MJT 4040 device combined with the companies Acrich2 technology allows operation on AC current without a driver, which usually weighs around 2~3kg, and allows design of light-weight LED streetlights. This allows the end user to use the existing streetlight pole infrastructure as well as its functionality (such as exist- ing wiring), which reduces the retrofitting cost drastically. Additionally, reliability is increased due to reduced component count and the elimination of electrolytic condens- ers commonly found in traditional ballasts and drivers. Tridonic: launches the new OLED lighting module range, LUREON REP, which achieves a luminous flux of more than 100 lumens, at dimensions of 99 x 99 mm². In addition, LUREON REP achieves a system efficiency of over 50lm/W in neutral white, which is much higher than that achieved by compa- rable products on the market. The square OLED module is offered with a colour temperature of 4000K, featuring extremely high levels of luminous emittance (up to 12,000 lm/m²) and luminance (4,000 cd/m²). (Fig 9)


APRIL 2013 LEDEngin: announces its most compact and efficient tunable CRI 90 white LED for black body dimming from 3000K to 1800K. The

LuxiTune light engine is the first to deliver warm colour dimming in a compact single emitter, maintaining color quality and 3 SDCM consistency over dimming range and service life. Luminous flux is 1100 lumens, equivalent to a 60W halogen lamp. Lumi- nous efficacy is 63 lumens per watt. At full intensity, colour rendering index (CRI) is 90 and LuxiTune maintains a CRI average of 85 and R9 red content of 70 as it dims. With a diameter of 50mm, LuxiTune makes it quick and easy to create a compact lighting fixture that works with standard 0-10V dim- mers or via a DMX interface. (Fig 10) Osram: launches the Ostar Stage LEDs of- fering up to 48 million candelas per square meter (Mcd/m²) and tuneable colour tones from cold white to warm white. Combined with their extremely low-profile design and glass cover with its anti-reflective coating, the Ostar Stage LED provides the basis for compact spotlights with an extremely narrow beam. This LED is ideal for use in moving head spotlights on stage, for booth lighting at trade fairs and for architectural lighting. The special feature of the new LED is its tuneable white light colour. Two warm- white and two cold-white chips, arranged diagonally in the package, not only enable colours to be mixed perfectly at compo- nent level but also allow all white tones between colour temperatures of 2700K (warm white) and 10,000K (cold white) to be produced with appropriate control. The LED achieves a high colour rendering index of 94 for warm white and 74 for cold white. In continuous operation (DC) the chips can handle an operating current of up to 900mA. This gives maximum values of 390lm in cold white (10,000K, and 210 lm in warm white (2700K,. At a typical value of 1.8 K/W the thermal resistance is very low and heat removal is therefore no problem at all. (Fig 11) Osram launched the the new Duris in three versions with different chip surfaces and therefore three different brightness levels.

The ideal application for the first version is wherever a large amount of light has to be emitted from a small surface area, for example in downlights and LED retrofits. At 3000K and a CRI of 80 it achieves very high brightness of 97lm and an efficacy of more than 100lm/W at an operating current of 150 milliamps (mA). Its optimized forward voltage of around six volts means that effi- cient driver solutions can be used that have a beneficial effect on the cost-effectiveness of the overall system. The second version is designed for high efficacy, achieving 125lm/W at 65mA with 24 lm at 3000 K. It is therefore designed for use in panel luminaires and linear retrofits in which individual light points should not be visible and low energy consumption is an important consideration. For these applications there is an alterna- tive in the shape of version three, which has only a slightly lower efficacy and is designed for optimum system costs. It achieves an efficacy of 113lm/W with a brightness of 28 lm – also at 3000 K. In addition to the three white Duris P5 emit- ters Osram launched five coloured versions including “deep blue” (450 nm), “blue” (470 nm), “true green” (528 nm), “yellow” (590 nm) and “red” (615 to 625 nm). At the heart of the different colours are state- of-the-art chip technologies from Osram, based on either the InGaN (Indium Gallium Nitrite) material system or InGaAlP (Indium Gallium Aluminum Phosphite) depending on the wavelength. Low forward voltages and optimized light extraction result in high luminous efficacies for all types. The “deep blue” version, for example, delivers a light output of 140 mW (at 100mA and 25 ºC), corresponding to a typical efficiency of 48 percent. (Fig 12) Philips: expands the Fortimo LED LLM Gen 3 outdoor luminaire range with a 6000lm module, bringing a lumen package suitable for replacing 50W and 70W high-pressure sodium lamps. The higher lumen package delivers efficient, high-quality diffuse
