190 Technical information LEDs in RIBAG lamps Quality RIBAG only uses LED components from manufacturers that are global leaders in efficiency and lighting quality. We generally use LEDs with consistent quality parame- ters for the entire product range. This means that lighting quality is always at the same high level, a great advantage for the user. Selection Specific tolerances result from the production of white LEDs.These tolerances are reflected in the colour location deviation, the preservation of luminous flux, and forward bias. RIBAG uses the above-mentioned criteria to select LEDs and, in doing so, provides the best possible quality for the customer. The LEDs used by RIBAG show an excellent colour tolerance of 3 SDCM (Standard Deviation of Colour Matching). Colour rendering (CRI) Colour rendering refers to a light source’s ability to repro- duce light as naturally as possible. A value of 100 corre- lates with accordance to a reference,though not automat- ically with an authentic colour impression in general. For this reason, we recommend a holistic approach to light quality that includes added criteria such as light colour, light level, light direction, etc., in addition to colour ren- dering. RIBAG uses a CRI target value of 85 for diffuse em- anating lamp and a CRI target value of 95 for all targeted emanating lamps as standard. Lifespan LEDs have a very low failure rate and,thereby,produce light for an extremely long period of time.The total failure of an LED is very rare. Early as the lamp’s development phase, RIBAG pays attention to reliable thermal management in order to reach a maximum LED lifespan. RIBAG usually specifies the lamps with L80/B10 100,000h,meaning that up to 100,000 hours,90%of the LEDs have at least 80%of the original luminous flux. High-voltage LEDs (AC) LED lamps fitted with high-voltage LEDs (AC) can be run directly with the standard voltage of 230 volts. The high-voltage LEDs used by RIBAG can be run directly with the existing 3-wire house installation and dimmed using a LED phase dimmer. High-voltage LED lamps by RIBAG met European EMC and Flicker regulations according to EN 6100. Additional references as well as an overview of compatibility with recommended dimmers can be found at www.ribag.com/dim. Controlling RIBAG lamps DALI DALI (Digital Addressable Lighting Interface) is the profes- sional, non-proprietary interface standard for dimmable electronic control gear. They are controlled with a 5-wire building installation via DALI lighting control or a DALI sys- tem. Every DALI lamp/control gear is individually digital and, therefore, individually addressable and can belong to multiple control groups. DALI is usually the interface standard for integration into superordinate building au- tomation systems. DALI L PE N DA– DA+ L PE N DA– DA+ S1 S2 S3 Z1 Z2 Z3 Z4 Gateway DALI Bus
