Functional road lighting

27.10.2016 | Products

Until recently, there has been little that local governments could do to reduce the cost of road lighting. It is an absolute essential element in keeping road users safe at any hour of the day, and ensuring the smooth flow of traffic in both residential and highway environments, but such a demanding role means expensive upkeep. Maintenance can be slow and dangerous; individual lamps are usually serviced on-site, and the physical components of traditional lamps such as high intensity discharge (HID) do not follow a set of standards. Most road lighting also only offers one level of brightness no matter the conditions, which can result in higher energy usage. LED lighting systems offer local governments an alternative to traditional lighting; one that is low energy, meets international regulation for brightness, and offers a simple and low cost interoperable maintenance system for quick and easy replacements and general upkeep.

The latest LED lighting systems offer a high power and high brightness alternative to traditional outdoor street lamps, such as high intensity discharge (HID). They also compete on long-term cost benefits, including long lifecycles under challenging conditions, and easy maintenance with interchangeable components for quick repairs and replacement of parts.

Unlike indoor applications, it is imperative that functional road lighting can withstand the variable conditions that come with outdoor installations. LEDs such as the Oslon SSL, Oslon Square and Duris P have the advantage over traditional HID lighting because their lifecycle is not affected by the negative impacts of UV rays, chemicals and the corrosive effects of weather and pollution. Both units use ceramic substrate, which has superior thermal performance and anti-corrosion characteristics over long periods of time.

Decorative street lighting

Like all public sector organisations, town planners within local governments are under increasing pressure to reduce cost wherever necessary. At the same time, they must also ensure durability and sustainability while reducing the carbon footprint of any new investments. With something as visible to the public as decorative street lighting, lighting must meet requirements for aesthetic values and serve its purpose to improve the look of local town centres and points of interest. It must also support the adaptive capabilities of the human eye and have a high colour rendering index (CRI) above 70 so that it is pleasant to observe. And as with all designs versus their functions, it must be robust and durable, and able to meet the challenges of external environments, including UV, chemical and corrosion. This is why increasingly, LED lighting systems are being chosen for street lighting applications.

Osram Opto Semiconductors’ outdoor LED lighting portfolio all fulfill lumen and colour maintenance requirements, ensuring a long and issue-free lifecycle when used in decorative street lighting applications. The OSLON SSL white and color portfolio with the ceramic based package and its superior corrosion robustness addresses perfectly the needs for long lifetime applications.

Consumer Outdoor

Luminaire makers have long been restricted by the inflexibility of traditional lamps when it came to consumer applications. With the consumer market preferring form over function, and unit price over long-term cost benefits, manufacturers have a challenging balance to strike in order to maintain demand and profitability. The emergence of the latest LED lighting systems for outdoor consumer applications has opened up a new opportunity in design freedom, while retaining all the benefits that LEDs have to offer in terms of durability, energy saving qualities and maintenance effort.

Lifetime is less of an issue for consumer outdoor applications, since consumers tend to make purchasing decisions based more on shelf unit price than long-term cost benefits. This enables manufacturers to reduce the cost of components and choose a more relaxed reliability, such as that offered by the Duris S LED family. Thanks to the high-quality epoxy package and silver leadframe, the new Duris S Outdoor versions deliver outstanding performance even in the harshest weather conditions. Their different footprints mean that the LEDs can meet an extremely wide range of customer requirements. The compact dimensions, high light output and narrow beam angles enable lighting designers to select the right products based on the specific requirements, giving them even more freedom than ever.

In view of the high-quality materials and robust silicones used, the Outdoor versions in the Duris S family have a life of more than 50.000 hours and are exceptionally resistant to corrosion. Like all the members of the Duris S series, the new LEDs offer impressive efficiency, optimum light output and excellent light color. The Outdoor versions can be applied in parking lot illumination, security lights as well as in garden and bollard lighting
