<strong>ROVASI</strong> DOWNLIGHTS PERFECT WHITELuminaires have to be capable of meeting lighting needs effici<strong>en</strong>tly and effectivelyresponding to the characteristics of the activity to be done in a specific area, theoccupants and the architecture of the place. Proper lighting can <strong>en</strong>hance taskperformance, improve the appearance of an area and have positive psychologicaleffects on users.However, it is oft<strong>en</strong> frequ<strong>en</strong>t that the action performed in a place and also the peoplemay change along the day; this will involve consequ<strong>en</strong>t modifications in illumination.Nowadays flexible lighting is always indisp<strong>en</strong>sable.<strong>ROVASI</strong> LED DOWNLIGHTS Perfect White is the ideal solution as they are easilyadaptable; they permit to modify not only the int<strong>en</strong>sity but also the white colourtemperature of the light achieving this required flexibility.Differ<strong>en</strong>t colour temperatures can beselected according the office schedule.<strong>ROVASI</strong> LED DOWNLIGHTS Perfect White show their str<strong>en</strong>gths in differ<strong>en</strong>tspaces and for differ<strong>en</strong>t purposes:· Work places/offices: increases productivity. Differ<strong>en</strong>t colour temperatures orint<strong>en</strong>sity can be selected according to the office schedule, the weather, the day light,the necessary att<strong>en</strong>tiv<strong>en</strong>ess in the activity and so on.· Hotel / hall: provides comfortable and relaxing ambiance in hotel/hospital/buildinglobbies combining it with the day light or the weather.· Confer<strong>en</strong>ce rooms/ auditoriums: facilitates optical separation from one activityto the next one. It is possible to associate the g<strong>en</strong>eral lighting to the show (classicmusic recital versus modern music concert).· Restaurants: adapts the lighting according to the food served, the area of therestaurant (kitch<strong>en</strong>/bar/waiting area/tables…), the meal (breakfast, lunch, dinner),guest profile, aim of the meal (family celebration, business meeting,…)· Multipurpose spaces: It helps to create flexible areas and sc<strong>en</strong>es, e.g. aerobicversus meditational or relax activities.· Museums: correctly r<strong>en</strong>ders colours. This is especially important in spaces wher<strong>en</strong>atural colour r<strong>en</strong>dering is a priority.· Retail: lighting in shops and stores is strategically important and decisive indetermining the perceived quality of products and materials. Good lighting makes itpossible to highlight products, making them visible. It also <strong>en</strong>courages people to buyand flows the customers if required.About the operational of this lighting solution, the luminaire is equipped with a LEDmodule and a driver. The driver can be controlled through a pushbutton or can becontrolled with DALI, in this case it is possible to memorize differ<strong>en</strong>t sc<strong>en</strong>es.LED DOWNLIGHTS Perfect White are available in following product ranges :NUCLEONS, ATOMIC, FOCUS, EFFECT, QUADRATIC, BSM, BSQ, V20, VSTAR,PLANE, SEAL, BSM SEAL.Lighting in shops is strategically important indetermining the perceived quality of products.94 GENERAL INFORMATIONThe combination of LED module and LED converter allows:· DALI system synchronisation.· DSI system synchronisation (if a conv<strong>en</strong>tional pushbutton is attached, it ispossible to control both the colour temperature and the light colour).· Switch DIM: through a pushbutton, you can regulate the light int<strong>en</strong>sity.· Colour temperature: through a pushbutton or through control via DALI it ispossible to change the colour temperature from 2700K to 6500K white. There are8 standard positions.· Colour Switch: through a pushbutton or through control via DALI it is possible tochange the colour in 8 pre-fixed positions, specifically for food shops:

The coordinates should always be inside the triangleindicated in this Planckian curve. As further away is the coordinate of thePlanckian curve, as much could defer the lum<strong>en</strong> level obtained.It is possible to memorize until 8 differ<strong>en</strong>t sc<strong>en</strong>es, so 8 coordinates.Other main characteristics important to empashize:· High colour r<strong>en</strong>dering index CRI > 90, excell<strong>en</strong>t colour r<strong>en</strong>dering.· Dimming range 15 to 100 %· Constant luminous flux about colour temperature· Dimming curve adapted to the s<strong>en</strong>sitivity of the eye· Standardized lum<strong>en</strong> packages for precise lighting planning.· High life time 50,000 hours at L70 (tc=65°C). Their long life significantly reducesmaint<strong>en</strong>ance and repair costs.· High system effici<strong>en</strong>cy of up to 65 lm/W at tp=65°C. High-quality light and optimumeffici<strong>en</strong>cy are no longer mutually exclusive. Reduce <strong>en</strong>ergy consumption by up to 40perc<strong>en</strong>t against conv<strong>en</strong>tional light sources.· The high effici<strong>en</strong>cy results not only in <strong>en</strong>ergy savings but also to a reduction in thethermal load. This means that smaller heat sinks can be used and more compactluminaires can be designed.Technical features:· LED chips manufactured by Lumitech.· Technology: COB (Chip on Board) over PCB (Printed Circuit Board).· The colour temperature changing is achieved through the combination of 3 LED chips: RED, GREEN and BLUE.GENERAL INFORMATION95
