What role does lighting planning play in showrooms? What lighting options are available in open-plan offices? How can an intelligent building automation system be implemented in the hotel or catering sector? These and many other questions about the trends in lighting and building management are addressed in individual exhibition “cubes”. Consultants from Osram and Siemens will also be on hand in four specialist forums to provide detailed information on the basics of LED technology, lighting planning with LEDs, lighting control, and intelligent build- Bildnachweis Alle Bilder: Osram benefits these bring the user in terms of light quality, energy efficiency and optical appearance, the „Building KnowLEDge Tour 2011“ also addresses the topics of convenience, safety and security, and cost-efficiency through the use of intelligent building technology.

When LEDs are combined with an intelligent lighting control system based on a Digital Addressable Lighting Interface (DALI), the user benefits from a greater level of convenience and saves energy, since the lighting is controlled according to need. Today, around 40 percent of the total U On the path to „Green Building“ Buildings are responsible for 40 percent of Europe’s final energy consumption. That is 10 percent more than the energy consumption of the entire transportation sector. The potential energy savings are high: heating, hot water, and lighting are responsible for around 65 percent of the final energy required by office buildings, for example. Dramatically reducing the energy consumption of new and existing buildings requires innovative heating systems, insulation measures, intelligent cooling and ventilation systems, and a practical energy management system. E-Installation | 02-2011 5 Bildnachweis Cover story New lighting solutions thanks to LEDs: an “illuminated mirror” Interesting facts about LEDs Light-emitting diodes (LEDs) have been in use in a variety of different application areas for over 30 years: from industrial systems and consumer electronics through to the transportation sector, where they are used in signaling systems and for interior and exterior vehicle lighting. Since the light yield of white LEDs today ranges from 40 to 100 lm/W (efficiency dependent on the color temperature and color reproduction), their use in general lighting applications is becoming increasingly common. Emergency and safety lighting and orientation and identification lights in particular are areas in which these LEDs have come into widespread use. Innovative LEDs deliver numerous technological advantages: from low power consumption and an extremely long service life, extremely small dimensions and high shock and vibration resistance through to low input power and (virtually) no heat dissipation. The user benefits from creative design options thanks to the variety of colors available, the compact dimensions and flexibility of the modules, a high level of economic benefits thanks to the low power consumption, long service life and low maintenance requirements, as well as from their extremely high reliability, even under harsh ambient conditions.
