LED source, a comparative analysis on lighting efficiency

Reduce volume of wasting resources and the usage of hazardous substances are main factors when is established a lighting solution, including new and old buildings. Increased productivity and reducing operating expenses for modernizing the office buildings should be done respecting also the rules of environmental protection. Regarding energy consumption, lighting allows significant savings that can be obtained if we create efficient lighting systems energy. The energy efficiency of lighting systems follows three main directions: making light sources with more efficient light; implementation of auxiliary equipment with high efficiency and low noise transmitted in the mains power supply and having a suitable management of lighting systems. Carrying out a system of LED lighting can achieve an economy of minimum 80% of the energy consumption, as compared to traditional lighting solutions. Choosing a suitable light source is the most important role in providing energy performance of the system of lighting.
