fényhatékonyság

Fényhatékonyság refers to the efficiency with which a light source converts electrical energy into visible light. It is typically measured in lumens per watt (lm/W). A higher lumen per watt value indicates a more efficient light source, meaning it produces more light output for the same amount of electrical power consumed.

Different types of light sources have varying levels of fényhatékonyság. Incandescent bulbs are known for their low efficiency, with much of the energy lost as heat rather than light. Fluorescent lamps offer better efficiency than incandescents, and compact fluorescent lamps (CFLs) further improved upon this. Light-emitting diodes (LEDs) are currently the most energy-efficient lighting technology available, significantly outperforming traditional options.

Improving fényhatékonyság is a key goal in lighting technology development, as it directly translates to reduced electricity consumption. This has significant implications for energy savings, lower electricity bills, and a reduced environmental impact by decreasing greenhouse gas emissions associated with power generation. When choosing light bulbs, paying attention to their fényhatékonyság rating can lead to substantial long-term benefits.
