8、t industry in technical standards related matters. The goal of the Program is to take a leading role regarding technology within the entertainment industry by creating recommended practices and standards, monitoring standards issues around the world on behalf of our members, and improving communicat
9、ions and safety within the industry. ESTA works closely with the technical standards efforts of other organizations within our industry, including USITT, and VPLT, as well as representing the interests of members to ANSI, UL, and the NFPA. The Technical Standards Program is accredited by the America
10、n National Standards Institute. The Technical Standards Council (TSC) was established to oversee and coordinate the Technical Standards Program. Made up of individuals experienced in standards-making work from throughout our industry, the Committee approves all projects undertaken and assigns them t
11、o the appropriate working group. The Technical Standards Council employs a Technical Standards Manager to coordinate the work of the Committee and its working groups as well as maintain a standards watch on behalf of members. Working groups include: Control Protocols, Electrical Power, Floors, Fog a
12、nd Smoke, Followspot Position, Photometrics, Rigging, and Stage Lifts. ESTA encourages active participation in the Technical Standards Program. There are several ways to become involved. If you would like to become a member of an existing working group, as have over two hundred people, you must comp
13、lete an application, which is available from the ESTA office. Your application is subject to approval by the working group and you will be required to actively participate in the work of the group. This includes responding to letter ballots and attending meetings. Membership in ESTA is not a require
14、ment. You can also become involved by requesting that the TSC develop a standard or a recommended practice in an area of concern to you. The Photometrics Working Group, which authored this standard, consists of a cross section of entertainment industry professionals representing a diversity of inter
15、ests. ESTA is committed to developing consensus-based standards in an open setting. Future Photometrics Working Group projects will include updating this publication as changes in technology and experience warrant, as well as developing new standards and recommended practices for the benefit of the

The light source is a perfect Planckian
27、 emitter at the designated color temperature. b. The transmission curves of the subtractive color filters are determined by the spectra of the CQS colors as shown in Appendix A2. With those parameters the CE values for 3200 K, 5600 K and 6500 K are tabulated in 4.2.3 of the standard. Continuing the
28、example used in A.3.1, the CE of a 5600 K Planckian locus source is 26.6% and thus the Color Ratio of our luminaire is 90/26.6 = 3.4. This suggests that our test luminaire is 3.4 times more efficacious at producing colored light than a hypothetical Planckian source with subtractive color filters. 20

It is understood that, for some SSL based luminaires, this may not always be possible or appropriate. Rather than
30、 having to use a single, prescribed, testing method, the reporter should make best efforts to report a modulation frequency appropriate to the technology being used. For example, a tester of an LED based luminaire using PWM to control the intensity of the LEDs should report that PWM frequency. If th
31、is frequency varies or a spread spectrum system is used then the range of variation should be reported. Other modulation or control methodologies may require reporting of other parameters. In all cases, it is the frequency of modulation of the output light intensity, not the electrical signals causing that variation, that is to be reported. 2016 ESTA. All rights reserved. page 13
