Lux Lumens and Watts per square meter

Click For Summary
SUMMARY

The discussion focuses on converting lux, a measure of illumination, to watts per square meter, which quantifies radiant energy. It is established that this conversion varies by wavelength, necessitating a specific conversion factor for accurate results. Participants suggest consulting the Illuminating Engineering Society of North America (IESNA) for authoritative guidance and potential conversion tables that detail these relationships across different wavelengths.

PREREQUISITES
  • Understanding of photometry and illumination concepts
  • Familiarity with the IESNA standards and publications
  • Knowledge of light wavelengths and their effects on measurement
  • Basic principles of energy and radiant flux
NEXT STEPS
  • Research IESNA guidelines on light measurement and conversion factors
  • Explore the relationship between lux and watts per square meter for various light sources
  • Investigate the creation and use of conversion tables for different wavelengths
  • Learn about photometric and radiometric measurements in lighting design
USEFUL FOR

This discussion is beneficial for lighting designers, engineers, and researchers involved in photometry, as well as anyone needing to convert illumination measurements for practical applications in lighting technology.

Homework Statement


I am looking for a conversion factor that will ultimately get me from units of lux (illumination) which is a weighted scale of light intensity, to watts per square meter, which is not weighted.


Homework Equations


None availiable


The Attempt at a Solution


I am informed that the conversion is different for each wavelength of light, so there may be a conversion table with a list of wavelengths?
