Bakit Mahalaga ang Luminous Efficacy

Ang Luminous efficacy (lm/W) ay sumusukat kung paano mahusay ang light source na nag-convert ng electrical power sa visible light. Mas mataas na efficacy ay nangangahulugang mas maraming liwanag per watt ng kuryente, na nagreresulta sa mas mababang energy costs at reduced environmental impact. Ang modernong LED technology ay dramatically nagtaas ng efficacy kumpara sa traditional lighting.

Paano Gamitin ang Calculator

I-enter ang kabuuang lumen output at wattage ng iyong light source. Ang calculator ay tutuklasin ang efficacy sa lumens per watt (lm/W) at ihahambing ito laban sa typical values para sa iba't ibang light source types. Ito rin ay magsasagawa ng estimate sa iyong annual energy costs at potential savings mula sa pag-upgrade sa mas efficient na lighting.

Energy Efficiency Tips

  • Ang Premium LEDs ay nakakamit ng 150+ lm/W efficacy, halos 10x mas mahusay kaysa incandescent bulbs
  • Kasama ang driver/ballast losses kapag kinakalkula ang total system efficacy
  • Mas mataas na efficacy ay madalas na may correlation sa better thermal management at longer lifespan
  • Isaalang-alang ang total cost of ownership kasama ang energy costs, hindi lang ang initial purchase price
