Osram’s Golden DRAGON oval Plus LEDs illuminate Russian cities 

Situated on the Trans-Siberian Railway, the Russian city of Kemerovo (which has 520,000 inhabitants) is converting to LED street lighting on a broad scale after installing 200 luminaires made by LLC TD Focus, equipped with Golden DRAGON oval Plus LEDs made by Osram Opto Semiconductors GmbH of Regensburg, Germany.

The USS-90 Magistral street luminaires have already been installed at various locations in Kemerovo. Another 200 will also be put up in the neighbouring village of Neftebazy and in Leninsk-Kusnetsky.

Each luminaire uses 90 Golden DRAGON oval Plus LEDs, which have been developed specifically for street lighting and meet the special requirements for energy-efficient lighting without light pollution. The Golden DRAGON oval Plus has special directional characteristics based on an integrated, durable silicon lens. Emitted light is only aimed at parts of roads or squares that have to be lit.

Osram Opto says that the range of color temperatures and shades of white that the LEDs offer meet the various lighting requirements at individual locations. From cold white (5000–6500K) to neutral or warm white (2700–5000K), the right solution is available for every application, the firm claims. Light output on average has luminous efficiency of 65–95lm/W.

Osram Opto says that LED street lighting also suits adverse weather conditions with freezing temperatures, rain, ice and snow, since their operating life and radiant power increase as temperatures fall. Compared with conventional solutions using 150W sodium high-pressure discharge lamps, the USS-90 Magistral streetlamp has total power consumption of just 105W, requiring far less energy. For the local authority this can save more than €20,000 annually (as well as more than 200kg in CO2). The LEDs’ durability can also reduce maintenance costs considerably.

Both the even illumination and good light quality improve perception of objects and therefore increase safety, says Osram Opto. The LEDs’ small size also gives lighting manufacturers greater design opportunities.

“With their great efficiency, long life and low maintenance, lighting solutions based on LED soon pay for themselves,” says Martin Wittmann, Osram Opto’s marketing manager of solid-state lighting.
