With LED technology, it can be implemented very specific lighting requirements. Because the fact-based modern light sources represent a gain for the lighting design of indoor and outdoor spaces represent to its compact dimensions, the energy efficiency and the architectural integration provides LED lighting enormous creative possibilities.
Through its optical efficiency, LEDs are more energy efficient than traditional light sources and by ongoing development doubles the efficiency of the LEDs every two years. With the advent of LED lighting technology to industry, households and communities reduce your energy consumption is already strong. By concentrators and reflectors, scientists succeeded in the light of the LEDs to bundle such that LED light sources can be used as car headlights and streetlights.
Pros and cons of LED technology in street lighting
The advantages of LED technology in the use of municipal street lighting are obvious:
- Long life
- Compact and thus variable designs
- Very high luminance
Nevertheless, there are also disadvantages:
- Challenging thermal management
- Still low light yield (40-110 lm / watt) (Updated 11/2007)
- High cost
- Yet limited lifetime, depending on the colour of light (white LED to 20,000 hours as of 6/2007)
- Light colour variation in production (different colour vision in several lights in a street)
The development of LED technology operates very intense. Therefore, it is expected that the properties of these lamps will improve very quickly and problems to be overcome.
Patented LED light source (LANZ-LED 50) come to relieve the situation, as and to keep our environment by polluting substances (mercury, lead, noble gases, etc.). In addition, it is possible almost completely and a maximize energy efficiency to reduce CO2 emissions and save on energy costs.
Intelligent Light Sources
Because LED lighting systems are controlled better let them called intelligent light sources implementer.
Street lighting, for example, reduced-energy powered and booted in the presence of people or vehicles to full brightness are.
