Good offices lighting design enables the occupants to perform their work efficiently without strain or fatigue. Common for all room types A dim lighting level on the floors can be compensated by a perception of brightness by illuminating the walls e. g. by wall-washers – this will define the whole space and helps with alertness. …
A strong learning environment relies on good lighting. Our eyesight is so resilient that lighting design for schools are hardly aware of the handicap imposed by poor lighting but this might result in slower reading, little understanding of what we read and diminished concentration. Generally, if regular maintenance, cleaning and replacements of the lighting system …
LEDs can be combined in any shape to produce highly efficient illumination. Individual LEDs can be dimmed, resulting in a dynamic control of light, colour and distribution. Well-designed LED illumination systems can achieve fantastic lighting effects both for the eye, the mood and the mind. Therefore, LED lighting provides many opportunities for Museums and Exhibition …

Smart lamps and luminaires combine technology breakthroughs in wireless communications and LEDs.Some of the smart features are: • Colour tuning, dimming, on/off and gradually changing/adjusting the lighting over time• Connectivity for activation of services, security monitoring and data delivery• Monitoring of energy consumption or customer visits/movements plus data storage• Signal boosting/extension• Built-in presence detector that …
High-quality LEDs can maintain their light output for tens of thousands of hours. The built-in electronic driver,however, may show a sudden failure so the led bulb lifetime of the whole lighting system has to be considered. The LED lamp lifetime is defined as the period during which a given fraction of the total number of …
Colour rendering defines the ability of a white light source to render object colours accurately. It is expressed by the general color rendering index (CRI) with values from 0 to 100, where 100 is the best (100 is provided by daylighting). Excellent color rendering index is achieved by lamps with a CRI above 90 which …
Glare appears in the case of very high luminance or large luminance contrast often due to lack of shielding from a window, reflection or from direct sight of the LED light sources in the luminaire. Normally, the eye adapts to any lighting situation, but if the lighting of the object or its background is too …
