LED Lighting Technology


LED lighting is not the technology of the future, but the technology of today. LED lights are the most environmentally friendly lighting solution available. Energy efficient LED lighting creates less carbon emissions, which helps our environment as well as saving you money.

The LED (Light-Emitting Diode) is a semiconductor light source, which emitted light is almost entirely concentrated in the visible light spectrum, the so called the luminous efficiency of high power LEDs exceeds  >100Lm /Watt and will continuously be improved during the coming years. LED lights are made of silicon and have an expected live time between 50 000 and 100 000 hours. No poisoned materials are used to manufacture LEDs and after its live time no special treatments are necessary to waste them. The street and park lights designed by TellCo Europe Sagl are mainly realized by using high power LED systems.

Solar electrical energy is the most popular planet's most direct and most clean energy, Solar energy as a massive renewable energy, every day of radiation reached the Earth's surface is approximately equal to 2.5 millions of barrels of oil, it can be said to be inexhaustible. Nowadays, alternative energy sources have become very important, due to the fact, that more than 170 countries have signed and rectified the Kyoto Protocol, which imposes national caps on emissions. On average, this cap requires over the time 2008 to 2012 that countries have to reduce their emissions by 5.2% below their 1990 baseline.

The TellCo Europe Sagl street and park lighting systems are using Mono-Crystalline solar modules, which have the highest efficiency. To improve the electrical energy generation, which may be important for certain locations and/or a high required output power the solar modules are manufactured with the Double Layer Techniques, the so called TellCo Europe Sagl High Performance solar modules.

Solar Modules in combination with LED Lights respond to the future requirement of energy saving and CO2 reduction. R.Fiedler Owner of TellCo Europe Sagl, Switzerland



- Efficiency:
LEDs emit more light per watt than incandescent light bulbs.
- Color: LEDs can emit light of an intended color without using any color filters as traditional lighting methods
- Lifetime:  more than 50,000 hours
- Cost-effective: more than 50,000 hours
- Low heat radiation 
- More than 70% energy saving 
- Increases the Quality of Life & Security
- Light for remote areas and portable generators: 
because of the low power requirement for LEDs, using solar panels becomes more practical and less expensive than running an electric line or using a generator for lighting in remote or off-grid areas. LED light bulbs are also ideal for use with small portable generators which homeowners use for backup power in emergencies.

Energy consumption

One kilowatt-hour of electricity will cause 1.34 pounds (610 g) of CO2 emission. Assuming the average light bulb is on for 10 hours a day, one 40-watt incandescent bulb will cause 196 pounds (89 kg) of CO2 emission per year. The 6-watt LED equivalent will only cause 30 pounds (14 kg) of CO2 over the same time span. A building’s carbon footprint from lighting can be reduced by 85% by exchanging all incandescent bulbs for new LEDs.

Economically sustainable

LED light bulbs could be a cost-effective option for lighting a home or office space because of their very long lifetimes. Consumer use of LEDs as a replacement for conventional lighting system is currently hampered by the high cost and low efficiency of available products.
