Luminous Intensity ஐ எப்படி கணக்கிடுவது

Luminous Intensity என்றால் என்ன?

Luminous flux (lumens) is the total perceived light output. Luminous efficacy (lm/W) measures how efficiently electricity is converted to visible light. LED: 80–120+ lm/W vs incandescent: ~15 lm/W.

சூத்திரம்

Luminous flux (lumens) = Luminous intensity (candelas) × Solid angle (steradians) | 1 lumen ≈ 1 candela × 1 steradian

படிப்படியான வழிகாட்டி

1Lumens = Watts × Efficacy (lm/W)
2Higher lumens = brighter light
3Higher lm/W = more efficient; lower running cost
4800 lumens ≈ old 60W incandescent brightness
