【 摘 要 】

LED vehicle lighting is developing very fast and it is becoming more and more available. Due to new EU regulations, it is installed in all new cars. They are also selected by the owner of older models of cars. LED revolution has brought not only better visibility, but also allowed to save money and protect environment. In order to support development and quick implementation of new advanced technologies reducing CO2 emission coming from vehicles, EC directive had to be introduced and it enables producers and suppliers to submit applications for approval of innovative technologies contributing to reduction of CO2 emission coming from passenger cars. Therefore, it was necessary to explain criteria for determination of which technologies should be qualified as eco-innovations and based on what rules and calculation methods, the level of reduction of CO2 emission may be determined. Total demand for energy of a vehicle equipped with bulbs (rear lamps) and halogen lamps (headlights) is about 60% of demand for energy for dipped headlights and 14% demand for rear position lights. If we use combination of xenon lamps and LED lamps for configuration of vehicle lighting, demand for energy will be reduced by 39%. If we used only LED lamps, energy consumption would be reduced by 60%. In this article, the authors presented a method of calculation of CO2 savings obtained by application of exterior lighting with LED diodes. Moreover, they presented optimization of energy consumption and savings thanks to application of LED technology and percentage reduction of CO2 emission.
