Luminous efficacy [lm/W] presented in these figures is derived from the ratio: K:
Luminous efficacy = (measured inside illu- mination)[lx]/(measured external solar
radiation) [W/m2]. The given external solar radiation is composed of the direct ...

This principally occurs outside visible wavelengths, so the remaining direct
radiation has a higher luminous efficacy. Direct luminous efficacy therefore: •
decreases with increasing atmospheric aerosol content and hence with
atmospheric ...

Solar Radiation and Daylight Models
A simple, yet robust model is the use of a single, averaged value of luminous
efficacy, a technique that has been adopted by several authors (Littlefair, 1985).
An average value of between 93 and 115 1m/W is quoted for beam luminous ...

For example, a 100 W incandescent lamp that supplies 1700 lm has an efficacy
of 1700 lm / 100 W= 17 lm/W. It is necessary to consider ballast losses in an
efficacy value, which can add 20% or more to the total losses. The luminous
efficacy of ...

2.4.3 Luminous efficacy Luminous efficacy is used to determine the effectiveness
of radiative or electrical power in producing visible light. The term “efficacy” must
not be confused with “efficiency.” Efficiency is a dimensionless constant ...
