UGR . DARK LIGHT.Glare is the objective reduction of visual performance and/or thesubjective alteration of vision caused by the appearance of highluminances or high luminance contrasts in the field of vision.Direct glare is glare caused by luminaires or a light source (theSun, for example).The International Commission on Illumination (CIE) defines glareas “visual conditions in which there is excessive contrast oran inappropriate distribution of light sources that disturbs theobserver or limits the ability to distinguish details and objects”.Such factors as eye adaptation or the angle between the pointat which a task is being performed and the illuminating lightsource has a significant impact on the experience of glare.The quantitative method for measuring direct glare is calledthe Unified Glare Rating. The unified glare rating (UGR) is ameasurement of the light within a specific environment, asrecommended by the International Commission on Illumination.The lower the UGR, the fewer glares is present.Another tool that can be used to assess direct glare is calledthe Söllner Diagram. The upper area of the diagram indicatesthe classification - according to the CIE and the DIN - for use inselecting the degree of glare permitted for a certain installation.Using the table of average illuminance for the installation, thedesired average value is selected by moving down the diagramto locate the luminance limit line.The diagram also indicates the luminance curve of the luminaire:if it sits to the left of the “dark” limit point, the luminairecorresponds to the type of glare required; on the other hand,the luminaire is glaring if its luminance curve intersects or sitscompletely to the right of the diagram.One decisive feature to assess the quality of a luminaire is thecontrol it has over glare and the level to which it keeps glareto a minimum. This means that luminaires can be designedfor the specific purpose of drastically reducing the chance ofglare. Such luminaires will have very low UGR values and theirluminance line on the Söllner Diagram will always sit to the leftof the dark limit curve.One of the philosophies upheld by the Technical Department atROVASI is to always develop quality luminaires that are energyefficient and visually comfortable.Parameters used for UGR calculation:Room reflectance: working plane (0.2) , walls (0.5), ceiling (0.7).Room dimensions: H=3m, x=4H=12m and Y=4H=12m.Luminaires spacing : 0.60m.COLOUR TEMPERATUREThe colour temperature measures how warm or cold the lightemitted by the lamp is.Low colour temperatures are related to warm colours (red) whilehigh colour temperatures are related to cold colours (blue). Thecolour temperature is closely related to the visualcomfort of aspace.The catalogue offers several possibilities in terms of colourtemperature, ranging from 2700K, 3000K or 4000K. In addition,some luminaires include modules and drivers that allow colourtemperature regulation (2700K-6500K). This way, the spacecan be illuminated according to different uses, or depending onpeople’s emotional needs.All LED modules above 6000K must comply with the UNE-EN 62471-2009 regulation for photobiological protection. Allmodules used by ROVASI comply with this regulation.CRI, Colour Rendering IndexThe CRI measures the ability of a lamp source to accuratelyreproduce all colours when compared with an ideal lightsource. Low CRI ratings will result in a low quality of the coloursreproduced. The human eye is adapted to natural light. Thesunlight CRI is 100, so light fittings close to this level will bring abetter visual comfort.This is an important index to be taken into account whendesigning the lighting of a space. The bigger the CRI index,the better the light quality. That is why ROVASI has taken intoaccount this parameter when designing its LED luminaires. Ahigh percentage of our LED fixtures is available in a CRI of 90.The regulations require a minimum CRI of 80 for interior use.98 GENERAL INFORMATION
LOR and Lm/WThe Light Output Ratio (LOR) is the ratio that describes theluminous flux of a luminaire regarding the luminous flux of thelamp that is built in. The LOR index is an indication of the lightenergy lost by light fittings. When making the lighting calculationsfor a specific space, it is very important to take into account thereal LOR index of the luminaire, and not the lamp output.Whenever a lamp is fitted in a luminaire, there is always adecrease in the final output obtained. That is why the use ofthe isolated lamp output is a source of erroneous results. LORor lm/watt of the whole luminaire is the correct parameter thatshould be used.ROVASI LED luminaires have been designed to give high LORvalues. Consequently, a high lumen level is obtained per wattconsumed, allowing high energy savings during the long lifetimeof the luminaires in the projects in which efficient ROVASIluminaires are used. The LOR data given cover the wholesystem (luminaire + driver).ROVASI LED luminaires are designed to provide a high outputthroughThe use of high quality modules.An accurate design of reflectors.An accurate choice of heat dissipation system.The use of high quality materials.PROTECTION INDEXIKLevel of shock resistance (according to CEI EN 50102).The IK rating classifies the level of protection that electrical appliances provide against mechanic impacts from outside. It is definedby standard IEC 62262.The degree of mechanical protection is identified by a code that consists of the letters IK followed by two digits.Code Impact Energy Test00 Non-protected01 Impact energy: 0,15 joules Resistant against an impact from an object of 200 grams thrown from a distance of 7,5cm.02 Impact energy: 0,20 joules Resistant against an impact from an object of 200 grams thrown from a distance of 10cm.03 Impact energy: 0,35 joules Resistant against an impact from an object of 200 grams thrown from a distance of 17,5cm.04 Impact energy: 0,50 joules Resistant against an impact from an object of 200 grams thrown from a distance of 25cm.05 Impact energy: 0,70 joules Resistant against an impact from an object of 200 grams thrown from a distance of 35cm.06 Impact energy: 1,00 joules Resistant against an impact from an object of 500 grams thrown from a distance of 20cm.07 Impact energy: 2,00 joules Resistant against an impact from an object of 500 grams thrown from a distance of 40cm.08 Impact energy: 5,00 joules Resistant against an impact from an object of 1,7 Kg thrown from a distance of 29,5cm.09 Impact energy: 10,00 joules Resistant against an impact from an object of 5 Kg thrown from a distance of 20cm.GENERAL INFORMATION99
