NettetLysutbytte (lm/W) Dette er hvor mye lys du får sammenholdt med energien som brukes. Glødelamper hadde et lysutbytte på litt under 15 lumen/watt. Halogenpærer ligger 30 til 40 prosent høyere. Utviklingen av LED nærmer seg nå 100 lumen/watt, slik at dette er langt mer effektivt for belysning enn tradisjonelle lyskilder. NettetLuminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt in the International System of Units (SI). Depending on context, the power can be either the radiant flux of the source's output, or it can be the total power (electric power, chemical energy, or others) … henry belin du pont https://cakesbysal.com

NettetLumens per watt (lm/W) refers to the energy efficiency of lighting: how much visible light you get for a given amount of electricity. For example, a traditional 60 watt incandescent bulb in the US produces 860 lumens. By dividing 860 by 60 watts you can calculate that for each watt of power it uses, the bulb gives out 14.3 lm/W. Each NettetNowadays we see LEDs with 300 lumen per watt luminous efficacy. Maybe in the laboratory. Right now commercially available white LEDs are about 200 lm/w. 400 lm/w is the practical upper theoretical limit. US DOE estimated over 250 lm/w by 2025.
