Russian cities gleam with LEDs from OSRAM Opto Semiconductors

Quotes/ Perspectives from LEDinside：

“Due to the nature of LEDs, thermal dissipation is an important requirement; hence, low temperature condition is conducive for extending the lifetime of the LEDs. Therefore, regions with high latitudes and low temperatures are particularly well-suited for LED street lighting fixtures” noted Roger Chu, Research Director at LEDinside.

Chu added, “In addition, with Russia's abundant natural resources, the country’s electricity rates are relatively lower compared to that in other countries. The environmental benefits of installing LED street lights far exceed its energy saving benefits.”

Kemerovo in Siberia is converting to street lighting with LEDs by OSRAM Opto Semiconductors on a broad scale. The city of 520,000 inhabitants on the Trans-Siberian Railway has installed 200 street luminaires made by LLC TD Focus, which are equipped with Golden DRAGON oval Plus LEDs. The city can therefore achieve significant savings in energy costs and CO2 emissions.

Two hundred LLC TD Focus street luminaires of the USS-90 Magistral type with OSRAM Opto Semiconductors’ LED technology have already been installed at various locations in Kemerovo. Another 200 luminaires will also be put up in the neighbouring villages.

Ninety Golden DRAGON oval Plus LED are used per luminaire. These LEDs have been developed specifically for street lighting and meet the special requirements for an efficient lighting solution without light pollution. The Golden DRAGON oval Plus has special directional characteristics based on an integrated, durable silicon lens. The LED light is aimed at the parts of roads or squares that have to be lit.

The range of color temperatures and shades of white that LEDs offer meet the various lighting requirements at individual locations. Light output is on average between 65 to 95lm/W.

Robust, weatherproof and economical
LED street lighting is also well prepared for adverse weather conditions with freezing temperatures, rain, ice and snow: their operating life and radiant power even increase as temperatures fall. Compared with conventional solutions using 150W sodium high-pressure discharge lamps, the USS-90 Magistral streetlamp with a total power consumption of only 105W, requires far less energy. For the local authority, this means savings of more than €20,000 a year. Additionally, the luminaires emit more than 200kg less of CO2 annually. With the LEDs’ durability, they can also reduce their maintenance costs considerably.

But it is not just the energy efficiency compared with conventional lighting solutions that looks impressive – both the even illumination and good quality light improve perception of objects and therefore increase safety. The LEDs’ small size also gives lighting manufacturers greater design opportunities.

Martin Wittmann, marketing manager of solid-state lighting at OSRAM Opto Semiconductors explains: “With their great efficiency, long life and low maintenance, lighting solutions based on LED soon pay for themselves. This protects not only the public households but the environment as well.”
