Iluminación

Acerca de Illuminance Conversion

Illuminance measures el/la amount of light falling on un/una surface—el/la total luminous flux per unidad area. It tells tu como well-lit un/una surface es, regardless of que color eso es o como mucho eso reflects. This distinction es importante: un/una black surface y white surface under el/la mismo lamp have identical illuminance, pero muy diferente luminance (perceived brightness). Illuminance es que un/una light metro measures y que lighting engineers specify cuando designing spaces—eso's el/la starting point for ensuring adequate visibility y visual comfort.

El/La SI unidad es lux (lx), equal un/una one lumen per square metro. Illuminance follows el/la inverse square law: doubling distance desde un/una point source reduces illuminance un/una one-quarter. Illuminance standards define minimum lighting levels for safety, productivity, y comfort in diferente environments—offices typically requerir 300-500 lux, while surgical operating rooms necesitar 10,000-100,000 lux. Building codes, occupational health regulations, y energy codes todo referencia illuminance requirements.

Our converter handles todo estandar illuminance unidades usado in lighting design, photometry, y regulatory compliance.

Common Illuminance Conversions

Illuminance Unidad Reference

Lux (lx) – El/La SI unidad of illuminance, equal un/una one lumen per square metro. El/La worldwide estandar for lighting specifications y recommendations. Typical indoor valores: home living room 50-200 lux, office workspace 300-500 lux, detailed assembly trabajar 750-1000 lux, surgical operating tabla 10,000+ lux. Outdoor: overcast dia ~1000 lux, direct sunlight 30,000-100,000 lux. Photography light metros read in lux o EV (related by EV = log₂(lux/2.5)).

Foot-candle (fc) – El/La US customary unidad, defined as one lumen per square pie. 1 fc ≈ 10.764 lux. Remains prevalent in American lighting industry, building codes (IESNA), y HVAC specifications. US workplace standards often specify pie-candles: general office 30-50 fc, detailed trabajar 50-100 fc. Converting mentally: divide lux by 10 for approximate pie-candles.

Phot (ph) – El/La CGS unidad of illuminance. 1 phot = 10,000 lux = 1 lumen/cm². Too large for la mayoria practico aplicaciones—even direct sunlight es solo aproximadamente 10 phots. Occasionally encountered in older cientifico literature y high-intensity aplicaciones like solar concentrators.

Nox – Un/Una unidad for muy low light levels, defined as 1 millilux (0.001 lux). Used in astronomy, night vision research, y scotopic (rod-mediated) vision studies. Full moonlight proporciona aproximadamente 250 nox; starlight aproximadamente 0.1 nox. El/La threshold of human vision es aproximadamente 0.01 nox.

Meter-candle – Un/Una older term equivalent un/una lux (1 metro-candle = 1 lux). El/La name emphasizes el/la relationship: illuminance desde 1 candela at 1 metro distance. Rarely usado in modern literature pero may appear in historical documents.
