Solid State Lighting Project

About the Project

The Science and Technology Council has identified a need for an unbiased investigation of solid state lighting (SSL) technologies, which includes LED emitters, for motion picture production. Issues with SSL have been identified regarding its ability to supplement and integrate with existing lighting technologies such as tungsten, fluorescent, HMI, and Xenon that are currently used in the production of motion pictures. The primary purpose of this investigation is to provide the industry with data needed to properly evaluate the impact of using SSL, as well as to provide a framework for the evaluation of future light emitting technologies as they are developed. The Council’s current efforts are focused on providing the motion picture industry with accurate and previously unpublished radiometric and photometric measurements (e.g., spectral power distribution, radiant flux, luminous flux, etc.) typical of various LED light sources currently in use.

How Long has the Academy Been Concerned with Lighting?

Since the Academy's inception. The first technical report ever published by the Academy was on a new invention – incandescent lighting. “Academy Reports - No. 1 - Incandescent Illumination” dated 1928, was written one year after the founding of the Academy. This 80-page report laid the cornerstone of incandescent lighting in motion pictures. It is a rigorous study encompassing all the relevant issues, including the contemporary economic advantages over alternatives such as arc lights. One fascinating aspect of the study was the emphasis on color rendering, which was entirely in the context of the black-and-white film era.

Project Objectives

The Solid State Lighting Project deliverables will include:

  • Radiometric and photometric measurements of emitter technologies
  • Comparisons between solid state emitters' radiometric and photometric measurements with the radiometric and photometric measurements typical of existing light sources
  • Comparisons of solid state light sources and existing light sources on colorimetry as well as tolerances for the evolving lighting technologies' integration with existing light sources and acquisition technologies
  • Develop a reporting framework for consistent comparisons between light sources

Parameters to be assessed:

Many of the parameters provided by the manufacturers for solid state lighting fixtures are typically not independently verified. The fixtures will be measured to provide the following information to the motion picture industry:

  • The technology currently in use (e.g., high power LEDs, tricolor LEDs, multicolor LEDs, mixed technology)
  • Intended use (e.g., flood, fill, spot)
  • Light output (radiant flux, luminous flux)
  • Power consumed (watts)
  • Available electronic adjustments (e.g., color temperature)
  • Spectral power distribution
