OrusAdvanced road lighting withinnovative Flat Beam ® technologyfor low-level mounting

Low height lighting needsAs engineers and specifiersknow, there are a numberof cases where conventionallanterns do not providethe best solution to roadlighting problems.Mounting heights may berestricted by structures or localregulations; obtrusive light maybe an issue; or maintenance mayhave to be completed quickly –for example, to reduce operators’exposure to fast-moving traffic,or where downtime for servicehas to be reduced to the absoluteminimum. In situations such asthese, conventional lighting isoften deficient.Thorn has applied its legendaryexpertise to addressing theseissues and the result is Orus, thefirst luminaire with Flat Beam ®technology. Designed to satisfystandard lighting criteria in a lowheight format, it offers engineersan exciting new resource inroad lighting.Innovation is often driven byobservation of the world aroundus – and Orus is a primeexample of this2

Introducing OrusA new road lighting luminairewith a special bi-directionaloptic, resulting in a unique lightdistribution; excellent uniformitywith no glare; low energy andabove all a mounting heightof 0.9mAs well as the usual Thornbenefits of low energyconsumption, sustainability andeasy maintenance, Orus usesFlat Beam ® technology to exceedrequirement levels at mountingheights of 0.9m. Where the useof columns or other structures isan issue, Orus delivers optimisedperformance without glare forroad users, in an attractivepackage with a choice ofmounting options.Furthermore Orus deliversquality in a lighting installationthrough three distinct attributes:Performance, Efficiency andComfort (PEC).Performance: Visual EffectivenessHigh Utilisation Factor> Good task luminanceSmaller burner lamps> Good task visibilityEfficiency: Minimising the use of energy70W maximum wattage> Use less energyElectronic control gear> Longer LifeComfort: People satisfaction and stimulationStreet/road optic> Selective ambienceOptic design> Glare free lightLower height> Visual Guidance3

Flat Beam ® ConceptFlat Beam ® technology addresses two issues unique tolow-level mounting:8m - 15m• By positioning the optical light engine below the driver’s eye line,it reduces the risk of direct glare• Thorn research on road surfaces of all types ensures that Orusdelivers optimum luminanceThe optical system offers a very sharp and controlled light distributionwhile optimising the efficiency of the lamp. The use of ceramic metalhalide lamps with small burners, between 35W and 70W, is the bestchoice in terms of light control, driver comfort and power consumption.Because Orus is a radical departure from standard luminaires,its characteristics are equally innovative:• It projects light transversally to the road (up to 11m) in a single-sidedarrangement• The optimised mounting height is 0.9m to ensure that no direct lightenters the vehicle• Optimum spacing is between 8m and 15mWith conventional luminaires, the ratio of spacing to mounting heightis between 3.5 and 5; with Orus the figure is between 10 and 18.Taking the ratio of lit width to mounting height, conventional luminairesproduce a figure between 0.8 and 1.2; with Orus the figure isbetween 8 and 13.Orus delivers uncompromised excellence. When observing roadsurfaces lit at ‘grazing’ incidence it can be seen that drivers perceivehigher levels of road lighting because the peak of the reflected beamis roughly in the direction of the eye. This does not mean higher glarebecause light distribution is sharply reduced – practically nil whenOrus is installed at optimum height. In fact, the Orus beam angle canreach 88° to the vertical where as standard luminaires are restricted to85°. This additional 3° underpin the exceptional performance of FlatBeam ® technology, which gives road users the benefits of increasedperceived ‘brightness’ and visibility.0.90mConventional Installation8m8m0,90m8m8m8mNew concept0,90m8m85°10m24m24m24m24mFlat Beam ® technology is aproduct of extensive Thorn researchinvolving optical design, theoreticaland simulated photometry androad testing of prototypesIt improves the optical efficiency of luminaires at reduced mountingheights, ensuring uniform light distribution with minimal glare.Primarily created for road lighting, the Flat Beam ® concept satisfies themost demanding standards for safety, helping drivers to:• Detect static or moving obstacles on the carriageway• Confirm the road configuration comfortably• Perceive the entire road surface and any issues at all speeds4

Conventional Installation85°Light incident rayFlat beam lightingReflection areaReflected rayReflected rayWe have extensively tested Flat Beam ® technology for glare, luminanceand flicker. A comprehensive Research and Development programmehas surveyed Flat Beam ® performance with a representative rangeof road surfaces in different weather and lighting conditions. The testprogramme included comparisons of the system against referenceluminaires in traffic-intensive conditions.The Research and Development team’s findings, show that forcarriageway luminance of about 1.5cd/m 2 , Orus luminaires deliverbetween 227 and 3507cd/m 2 while dipped car headlights emitbetween 4521 and 46770cd/m 2 . This means that Orus is a tenth thebrightness of car headlights, hence no glare.Because Orus luminaires can be installed with spacing between8m and 15m, this flexibility allows the eyes to adjust dependenton speed, meaning that the flicker effect is maintained below 4Hzand in most cases less than 2.5Hz, keeping driver discomfort to anacceptable minimum.88°Dipped car headlightsOrus fittings5

ApplicationsThe system can be used wheretraditional road lighting usingcolumns or façade mounting isnot feasible, for reasons such as:• Ease of access• Extreme weather• Structural fragility• Maintenance difficulties• In the vicinity of airfields orother sensitive areas• Risk of obtrusive light• Other environmental orresource issuesOrus is not simply an idealsolution in such applications,it may even be the only solution.Yet it still conforms to – andmay even exceed – industrystandards and other operatingrequirements:• The unique flat beam of lightproduced by Orus can help toreduce light ‘leakage’ whilestill providing comfortablelighting for all road users• Orus places light exactly whereit is required• Orus combines optimumperformance and energyefficiency with safe andeasy installationRN 202 - Ville de NICE © Photo J.

8mOrus ‘Road‘ optic10m8mOrus ‘Street‘ optic10mOrus can be specified for use onroads with or without pedestriantraffic. Without pedestrians,the optical design directs lightentirely onto the road. Wherepedestrians are present, Orusis available with an alternativeoptical design which createsa ‘circle’ of light around theluminaire, enabling drivers todetect a pedestrian’s entire body.This option also allows for facialrecognition by other pedestrians.ClassicOrusOrus is also an excellent solutionwhere obtrusive light has to bereduced. For example, it can bespecified in certain residentialareas, or in areas where thesurrounding buildings areilluminated and road lightingshould therefore be unobtrusive.The Flat Beam ® technology usedin Orus also makes the systemsuitable for use in parks andgardens. Here the luminaires canspread light at low level withoutdistracting attention from otherilluminated features.7

The Orus RangeRoad safetyOrus ensures better hazard andpedestrian visibility as well asimproved driver comfort. Thisunique luminaire combinesluminance and uniformity withlimited glare, revealing obstaclesand road surface irregularities. Atthe same time the low mountingheight acts as a good optical andvisual guide to the road layout.Durability blockOrus is constructed from highquality materials and engineeredfor low maintenance and a longoperating life. Metal componentsare either die-cast aluminiumor stainless steel, and thevisor is made from strong, UVstabilised and scratch protectedpolycarbonate. To withstandthe additional rigours of itslow mounting height, the entireOrus structure incorporatesan IK10/40 joules rating todefend it against harsh roadusage as well as vandalism.Tamper-resistant screwscombine protection with easymaintenance. Both optic andgear comply with IP66.Easy installation andmaintenanceIn areas where access is hard ormaintenance time is restricted,Orus is the perfect solution. Itis light, easy to handle, and isdelivered complete and ready toinstall in one box.VersatilityThe lighting head can be top orside mounted or suspended,enabling Orus to be integratedinto most existing infrastructures.As standard the system comeswith stirrup or bollard, but othermounting options can be developed.Energy savingWith a range of lamp optionsfrom 35 to 70W, Orus simplydelivers high performance withlow energy consumption. The useof electronic ballast enhancesthese energy savings and alsoincreases lamp life expectancy.Environmentally friendlyAll parts of Orus can berecycled, and its very preciselight distribution minimises ‘spill’and obtrusive light.Orus offers a number of benefitswhich make it suitable for localauthorities, engineers andlighting designers alike8

Calculations show that TI isconsiderably below 10% while,luminance and uniformity exceedrelevant standards.The system is designed with aspecific lamp burner cap sothat direct light cannot reachthe eyes of a driver or the rearmirrors of a car when installed atcompulsory height of 0.9m. In acomplete installation, Orus offersdrivers a unique ‘guidance’ effectwhich tracks the contours of theroad, ahead and behind.Orus can be installed eithersingle-sided, with luminairespacing between 8 and 15m, oron both sides of the road withthe same spacing. In the latterconfiguration it will cover roadsup to 20m wide, giving amplecoverage for roads with multiplelanes including cycle lanes andcentral reservations.Light output from Orus luminairesis surprisingly resistant toobstruction by queues of traffic.Tests have shown that there isno occultation nor distractingshadows, while light emitted fromthe system is distributed aheadof, behind and beneath vehicles.It is also reflected by the roadsurface. Spacing options between8 and 15m also reduce any‘pools’ of darkness, while lightingfrom vehicles further maintainslighting levels.Orus luminaires mix perfectlywith classic column mountedsystems. Because they usewhite light they can be used tohighlight sections of the highwaywhere care is required, as in ahazard black spot or area ofrestricted speed.The wide choice of lamps – from35 to 70W HIT-CE G12, or60W HIT-CE PGZ12 Cosmowhite– gives planners ample scope toadjust Orus to any project.9
