A Energija - Light up the future
Why LED technology?
- 90% of power consumed by ordinary light bulbs is used for heating, rather than to illuminate. This means that mere 10% of energy goes for actual lighting, while LED energy efficiency is up to 85%
- LED lights consume up to 85% less energy than incandescent lights.
- LED light bulbs are much more eco-friendly because they do not contain any toxic gases or fragile glass components.
- LED lights have a long lifespan - 50,000 hours, which is significantly more than traditional incandescent light bulbs, where lifespan is only up to 1,500 hours. With LED lighting, maintenance costs are significantly lower.
- No light pollution: LED light beams at a well-focused angle and does not beam upwards.
- Lighting accounts for more than 20% of total electricity consumption in the world.
Savings and protecting the environment
Light pollution is every form of artificial light which shines outside the areas it is intended to illuminate, especially the light directed above the horizontal. The consequences include sky glow over towns and cities, glare, dazzle, reduced visibility at night and unnecessary energy consumption. In order to avoid those unwanted consequences, it is necessary to gradually do away with old inefficient technologies and replace them with modern energy-efficient ones.
Savings in energy with LED lights compared to Mercury and Sodium lamps is 50 to 80 %. The lifespan of LED lamps when working 10 hours a day is more than 14 years, which is 5 to 10 times more than for Mercury and Sodium lamps. A controlled, directed beam of light provides an even illumination of the street area. Lens-shape prevents the unwanted reflection of light.
Savings and reducing energy consumption
Today everybody is talking about reducing costs, protecting the environment and about advantages of LED lights. If you want to know what it really means to reduce costs and to protect the environment, read on. Our example shows a company with 35 employees. We have calculated the savings and the energy consumption before and after the modernization of lighting. The results are more than obvious.
A Slovenian company (with 35 employees and premises of 3,000 m2)
Energy consumption € / year:
The comparison of costs before and after the modernization shows us the savings made by new lighting. The savings amount to €14,659 annually due to lower consumption only.
Savings in maintenance largely depend on lifetime of light sources and lights with accompanying electronics.
Consumption kWh / year:
In this case, the company will reduce consumption for 149,582 kWh. Energy consumption is definitely a big expense for every company, which can be substantially reduced.
Saving energy and having lower costs are certainly the goals of every company and household. LED lighting is definitely the future of our homes, companies and cities.
Protecting the environment
Every reduction in electricity consumption:
- reduces the negative effect on the environment,
- indirectly reduces CO2 emissions.
Data for Slovenia show that for every consumed kWh of electricity there is 0.55 kg of CO2 emissions. With reduced electricity consumption a company can annually reduce CO2 emissions for 82,270 kg.
How ordinary lights are used ?
DO WE EVER WONDER WHERE ALL THE ''WATTS'' FROM THE BULBS AT OUR APARTMENTS GO?
Incandescent light bulbs are a small fire in disguise, which is proven by a fact that approximately 95% of energy is transformed into heat and only 5% into light. In times of constant development, it is difficult to understand poor efficiency of regular light bulbs which are present almost everywhere. Why did development on such an important matter stagnate for such a long time? We must realize that the use of each light bulb contributed to cutting forests, stemming valleys and building power plants. Due to mere 5% of light, emitted by a regular light bulb, today's environment is very different from what it could be if the light bulbs had a better efficiency.
LED lights have a very long lifespan of 50,000 hours, which accounts for more than 11 years of non-stop lighting. The lifespan of 50,000 hours means at least 70% luminosity, which is declared for LED lights, but the diodes themselves emit light much longer. If we compare LED to regular incandescent light bulbs, with an average lifespan of 1000 hours, we can see that LED diode lasts at least 50 times longer. The energy consumption for LED lights is extremely low compared to regular light bulbs. Of course, these are not the only advantages of LED lights.
