Kurzfassung

A German innovative company has developed and produced high-power LED-applications and lamps. They invented a very efficient and modular power-LED streetlight. It has the advantage to be compatible with nearly all current and prospective high-power LEDs. They are searching for licensees across Europe for manufacturing (especially aluminium die casting) and joint research activities to improve power supply and illumination efficiency.

Details

The municipalities of the cities and communes are confronted with many different problems with their street-lighting today, because the actual used techniques are inefficient, expensive and harmful to the environment.

These high-power-LED-based streetlights can solve the described problems of the municipalities by saving energy and operating costs. The well known light emitting diode (LED) is today a new source of light. LEDs are no longer only status lights for machines. They are already able to reach 100lm/W. And this will not be the end of their abilities. In future the LED will become more and more efficient with a higher light-output.

The streetlight uses 64 high-power LEDs of the newest generation. Most of the street lighting standards can be achieved by the high-power LED streetlight.

Additionally, it only needs a low amount of energy and has a lifetime about 70,000 hours.

Another benefit of the LED technique is that only a small band of light is emitted. There are no infrared or ultraviolet emissions. This will save many different types of insects, because many insects feel attracted by these types of light radiation. Humans do not see infrared or ultraviolet light, so it is inefficient for a light source for humans to emit these wavelengths.

The lifetime of LEDs is very long, up to ten times longer than the lifetime of incandescent lamps. This fact will not only save money, it also reduces the waste of materials and the recycling of hazardous gases and substances.

All outcome of the project and all measurements are certified by a University.

Innovative Aspects:
This power-LED streetlight is more effective and much brighter than the most conventional streetlights with bulbs or fluorescent tubes. The last measurements showed that 70 lm/W for the whole streetlight can smoothly be achieved. This is a very high value if you imagine that sodium metal vapor streetlights have an efficiency between 40 lm/W and 60 lm/W.

The most competitive products have an inefficient thermal-management. The whole electrical system is in interaction with the thermal behavior of the LEDs. The thermal-management is the basic thing to get a high efficiency and a long lifetime for the LED. The company’s patented case has a thermal barrier between the LED-drivers and the LEDs. This system minimizes the interaction of these two systems and guarantees a temperature difference of a minimum of 10 degrees Celsius between the LEDs and the drivers.

By using only high-quality components for the streetlight, the company is able to reach the LED lifetime of 70,000 hours for the whole streetlight. They also developed a new, high-efficient LED-driver for this streetlight with an overall efficiency higher than 90%.

Another major advantage of the streetlight is the failure save mechanisms. The LEDs have a failure save of 1:64. And even if 16 LEDs will fail, the streetlight is still conform to the lighting-standard. The drivers have a failure save of 1:4. Both values together provide the streetlight with an overall failure save of 1:34.
