What is the CIE?

The International Commission on Illumination, also known as the CIE from its French title, Commission Internationale de l´Eclairage, is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting, color and vision, and image technology.

With strong technical, scientific and cultural foundations, the CIE is an independent, non-profit organization based in Vienna, Austria, that serves member countries on a voluntary basis. Since its inception in 1913, the CIE has been a professional organization, accepted as representing the best authority on the subject and is recognized by the International Organization for Standardization (ISO) as an international standardization body.

The CIE provides a unique bridge between fundamental research and application. The technical activities of CIE are carried out under the responsibility of six Divisions each covering one sector of light and lighting. Each Division establishes Technical Committees (TCs) to carry out the technical program of the Division. The Technical Committees collectively incorporate a broad international base of scientific knowledge, and together with the lighting application community forge solutions to the problems encountered by our members.

CIE Divisions

Division 1 —Vision and Color

Division 2 —Physical Measurement of Light and Radiation

Division 3 —Interior Environment and Lighting Design

Division 4 —Transportation and Exterior Applications

Division 6 —Photobiology and Photochemistry

Division 8 — Image Technology

What is the United States National Committee (USNC)?

The actual members of the CIE are the national committees of the member countries. There are more than 35 member countries from all six populated continents. The USNC represents the United States in the CIE international organization. USNC has the official US vote on matters relating to the CIE and appoints official US members, and alternate members, to the CIE Divisions. USNC’s mission is to promote the proactive participation of its members in governance, technical, and standards activities of the CIE. 

Who makes up the USNC?

The USNC is made up of individual voluntary members. As an organization, the USNC acts as the intermediary between the CIE and these individual members for the review of proposed CIE international standards.

What does the USNC do?

The USNC regularly conducts symposia and workshops held in conjunction with the annual meeting. Additionally, it maintains liaison and technical interaction with constituent societies, corporate, government and other organizational members so that these can benefit from the work of the Technical Committees, particularly reports and standards produced. The USNC is a source of information on technical expertise in various areas of lighting. The USNC sees that US industry and government interests are represented in the development of technical reports and standards.
