Luminous intensity, английский
- The luminous flux per unit solid angle in a specific direction from a point source of light; in practice, an interior source may be considered a point source if the distance exceeds 5 to 10 times the maximum source dimension of the luminaire; in us customary units, expressed in candlepower; in si units, expressed in candelas. luminous-intensity distribution curve a polar plot representing the light intensity as a function of angle about a light source. luminous transmittance 609 luminous-intensity distribution curve luminous paint 1. phosphorescent paint, which, after activation, continues to emit light (even in darkness) for several hours. 2. fluorescent paint, which has a high light reflectivity because it reflects absorbed ultraviolet energy as visible light.
- Measure of a light source’s power output per unit solid angle emitted or reflected from a point, when weighted by the photopic spectral luminous efficiency response curve. luminous intensity is measured in candela. compare luminance.4 lux (lx): si unit of illuminance, equal to one lumen per square meter (1 lx = 1 lm·m–2). m
- Luminous flux per unit solid angle in the direction of interest. measured in candela. compare luminance; radiant intensity. lux (lx): si unit of illuminance, equal to one lumen per square meter (1 lx = 1 lm/m2).
