LED in the limelight
Curtains up for Zelion H modules, the next generation of efficient special effect lighting
Until recently, professionals tended to use halogen lights for lighting production of spectacular stage shows or buildings; now, though, OSRAM Zelion H offers a particularly energy-efficient, durable and robust alternative. Compact, available in light colours white, red, blue and green and with two different reflectors (6° and 10°), this module with its flexi ble applications impresses with its very high axial luminous intensity, achieved with the aid of four highly efficient light diodes in combination with an optimised reflector design. These LED modules are suitable for a wide range of different applications and are easy to integrate into different luminaires. Extensive optical and thermal simulations and tests throughout the development process, including some in the airfield sector, have made OSRAM Zelion H an adaptable light source suitable for a wide range of applications. It will continue to perform even when conditions turn somewhat rougher, for example as the result of vibrations during a concert.
Energy-efficiency and reduced maintenance requirements
Energy efficiency is a particular hallmark of Zelion H LED systems. With a light intensity of 2000cd per Watt, which equals a 75 per cent energy reduction in comparison to a halogen solution (500 cd/W). Additionally one 48W halogen lamp (24 kcd) can be replaced by only four LEDs with a total of 19W (38 kcd) which results in further saving potentials.
There is no need for coloured filters required for conventional lamps, as the LEDs used in Zelion H systems emit coloured light. In addition to energy savings, these systems also make another significant contribution toward lower operating costs: considerable savings can be achieved in the maintenance in difficult to reach areas (such as high ceilings), because Zelion H modules can be used continuously for up to three years. In terms of durability, they are also far superior to other lamps: The service life of a halogen lamp is approx. 3000 hours, that of an LED solution to at least 25,000 hours.
OSRAM (Munich, Germany) is part of the Industry Sector of Siemens and one of the two leading lighting manufacturers in the world. Sales for OSRAM worldwide totalled to €4.0 billion in fiscal year 2009, 88 percent of which came from outside Germany.
OSRAM is a high-tech company in the lighting industry. Over 66 percent of sales come from energy-efficient products. This global player employs more than 39,000 people worldwide, supplies customers in some 150 countries and has 46 production facilities in 17 countries (September 30). www.osram.com
