Less energy, more light quality – Russian cities gleam with LEDs from OSRAM Opto Semiconductors

“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 village of Neftebazy and in Leninsk-Kusnetsky.

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 a special directional characteristics based on an integrated, durable silicon lens. The LED light is only aimed at the parts of roads or squares that have to be lit.

The range of color temperatures and shades of white that light-emitting diodes offer meet the various lighting requirements at individual locations. From cold white (5,000 to 6,500K) to neutral or warm white (2,700 to 5,000K) the right solution is available for every application. Light output is on average between efficient 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. Plus, 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 balance 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.”"

Indeed, the energy savings from using energy efficient light bulbs are quite noticeable, but what about the lighting fixtures themselves? Is it important to use proper lighting fixtures to house these energy efficient light bulbs? Absolutely! In fact, I’d argue proper lighting fixtures take precedent over energy efficient light bulbs. Why? Simple. If a light lacks shielding, then a light will leak into the sky. This phenomenon is known as light pollution. Regrettably, light pollution litters much of the night sky around the globe, due to poor lighting principles. Shielding directs the light downward where it’s needed. In addition, when the light is focused downward, it becomes more concentrated, ergo a smaller light bulb would perceptibly emit more light. High wattage bulbs, for the most part, would be unnecessary. Incorporating motion sensors with high efficiently light bulbs and shielded lighting principles, would further reduce not only our electrical footprint, but also the ‘criminal-footprint’. Studies have indicated that motion-sensorsed fixtures deter crime better than excessive, constant light. From an environmental, an economic and a fiancial standpoint, the choice should be obvious. Shielded lighting fixtures + energy efficient light bulbs + motion sensors = an efficient, environmentally conscious solution to a 100% solvable problem. Here at Starry Night Lights, we take pride in the fact that all our products are 100% shielded. Guaranteed. Reading this post is the first step towards a brighter future.

Let there be night!
