实际应用场景

中国的《建筑照明设计标准》(GB 50034)规定了各类场所的照度标准:办公室300-500 lx、教室300 lx、商场500 lx、医院200 lx。在摄影中,一个专业影棚的照度约为1,000-2,000 lx,摄影师需要根据照度调整光圈和快门速度。夏季正午阳光直射可达100,000 lx,而月光只有约0.5 lx。室内植物补光:多肉植物需要10,000-20,000 lx,绿萝等耐阴植物5,000 lx即可。亮度的单位换算中,1 fc(foot-candle)= 10.76 lx,进口照度计常同时显示两个单位。文物保护中,书籍和画作的照度限制在50 lx以内。消防应急照明的照度要求:疏散通道不低于0.5 lx。LED灯具参数中,流明(lm)表示光通量,照度(lx)表示单位面积的光通量。智能家居传感器中的光照传感器返回lx值,用于自动窗帘控制。日光温室中,光照强度影响作物光合作用效率,农民根据lux调整遮阳网。

Quick Answer: 照度 Converter

Convert 照度 instantly — enter any value and get all units at once. Common illuminance conversions include lux to foot-candles (1 lx = 0. Illuminance conversion is used in photography and cinematography, workplace lighting compliance (OSHA/EN standards), greenhouse planning, stage lighting design, and architecture.

How the 照度 Converter Works

Our illuminance converter converts between lux, foot-candles, phots, and related units using exact conversion factors. Enter a value in any unit and see instant results in all supported illuminance measures.

Formula & Sources

Lux is SI (lm/m²). 1 foot-candle = 1 lumen/ft² = 10.7639 lux. Phot = 10,000 lux (CGS). Based on CIE photometry.

Worked Example

Example: 500 lux office = 46.45 foot-candles. Photography: 1000 lux → EV ~6 at ISO 100.

Common 照度 Conversions

Common illuminance conversions include lux to foot-candles (1 lx = 0.0929 fc), foot-candles to lux (1 fc = 10.764 lx), and lux to phot (1 phot = 10,000 lx). Typical office lighting is 300-500 lx, while direct sunlight exceeds 100,000 lx.

When to Use 照度 Conversion

Illuminance conversion is used in photography and cinematography, workplace lighting compliance (OSHA/EN standards), greenhouse planning, stage lighting design, and architecture.

Accuracy & Common Mistakes

All factors are stored unrounded and computed in double precision. We avoid cumulative rounding by converting via a base unit. Always verify critical results with a second source for safety-critical tasks.

Frequently Asked Questions
