The goal of the Program is to take a leading r

8、ole 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 communications and safety within the industry. ESTA works closely with the technical standards efforts of o

9、ther organizations within our industry, including USITT and VPLT, as well as representing the interests of ESTA members to ANSI, UL, and the NFPA. The Technical Standards Program is accredited by the American National Standards Institute.The Technical Standards Council (TSC) was established to overs

10、ee and coordinate the Technical Standards Program. Made up of individuals experienced in standards-making work from throughout our industry, the Council approves all projects undertaken and assigns them to the appropriate working group. The Technical Standards Council employs a Technical Standards M

11、anager to coordinate the work of the Council and its working groups as well as maintain a “Standards Watch” on behalf of members. Working groups include Camera Cranes, Control Protocols, Electrical Power, Floors, Fog and Smoke, Followspot Position, Photometrics, Rigging, and Stage Lifts.ESTA encoura

12、ges 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 four hundred people, you must complete an application which is available from the ESTA office. Your application is s

13、ubject 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 requirement. You can also become involved by requesting that the TSC develop a standard or

14、 a recommended practice in an area of concern to you.The Followspot Positon Working Group, which authored this Standard, consists of a cross section of entertainment industry professionals representing a diversity of interests.

31、 of public assembly1 Introduction1.1 PurposeThe purpose of this document is to offer guidance and to make recommendations for the placement and arrangement of permanent followspot positions in places of public assembly. Information in this document is not intended to conflict with any federal, state

32、 or local codes, statutes, ordinances or regulations, or to replace competent professional advice.1.2 Scope This document makes recommendations for the operational and functional aspects of permanent followspot positions within places of public assembly, including the determination of their location

33、 within the venue, their physical space requirements, and the safety considerations associated with their use. The scope of this document includes accessibility and environmental concerns, but only to the extent that these concerns relate to (a) the location and configuration of followspot positions

34、, (b) the working environment created by these areas during their intended use, and (c) the working environment created during other activities incidental to their intended use.Temporary followspot positions are not included in the scope of this document.2 Definitions2.1 followspot: A manually opera

35、ted spotlight intended specifically for illuminating moving objects or performers.2.2 followspot position: A purpose-designed, permanently located space or platform, specifically intended for one or more followspots.2.2.1 followspot booth: A followspot position that is an enclosed room or space spec

36、ifically intended for the placement, use, and operation of followspots. 2.2.2 followspot platform: A followspot position that is an open-sided platform specifically intended for the placement, use, and operation of followspots. 2.3 obstruction: Any interference to the movement of the followspot, its

37、 operator, or any interference in the path of the followspot light beam, between the intended followspot position and the performance area, whether predictable or not. Examples of physical obstructions include building structural framing elements and any equipment attached to the building structural

38、 framing elements. 2.4 pan angle: The included angle formed by the followspots horizontal limits of movement, measured at the followspots beam centerline. 2.5 qualified lighting specialist: A person who by possession of a recognized degree or certificate of professional standing, or who by extensive

39、 knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to live event lighting using followspots.2.6 railing: Any barrier that is intended to function as an OSHA or building code compliant guardrail 2016 ESTA page 1ANSI E1.28 2011 (R2016)

40、, Guidance on planning followspot positions in places of public assembly2.7 Special-Purpose Industrial Occupancy: An industrial occupancy in which ordinary and low hazard industrial operations are conducted in buildings designed for, and suitable only for, particular types of operations, characteriz

41、ed by a relatively low density of employee population, with much of the area occupied by machinery or equipment.2.8 throw distance: The line-of-sight distance from the front of the followspot to its intended target when the target is at its farthest point from the followspot.2.9 tilt angle: The incl

42、uded angle formed by the followspots vertical limits of movement, measured at the followspots beam centerline. 3 Type ClassificationsThe recommended criteria for followspot positions are determined by the venue size and its intended function (i.e., the programming). In general, followspots that must

43、 light a stage that is a long distance awaywill be physically larger and require more power than followspots lighting a stage that is closer. Also, if the general level of illumination on the stage is high, the followspots will need to be larger and use more power than they would if the general ligh

44、t level were lower. The following type listing should be modified tosuit the particular situation and is only a rough guide. For example, if the throw distance used in the type listing suggests a type 2, but the stage is expected to be brilliantly illuminated, perhaps type 3 should be used for the d

45、esign criteria.3.1 Type 1 positionA followspot position where the throw distance from the followspot position to the stage is up to 80 feet (24.4 m). 3.2 Type 2 position A followspot position where the throw distance from the followspot position to the stage is 80 to 150 feet (24.4 to 45.7 m)3.3 Typ

46、e 3 position A followspot position where the throw distance from the followspot position to the stage is over 150 feet (45.7 m).4 Space and Location The intent of this section is to provide technical guidelines for permanent followspot positions.4.1 Location Followspot positions require clear lines

47、of sight from the fixture light source and from the operators eye to all locations within the venue that the followspot is intended to illuminate. The horizontal and vertical angleof incidence between the beam of light to the performer or object to be illuminated is a critical design decision in det

48、ermining the location and layout of the followspot position. The specific criteria vary from venue to venue and may change for individual followspot positions within a single venue.Lighting in a performance venue is an artistic endeavor. There are many suitable geometric relationships between the lo

49、cation of the followspot position and the target. However, there are some general recommendations that apply to a great many venues. 2016 ESTA page 2ANSI E1.28 2011 (R2016), Guidance on planning followspot positions in places of public assembly4.1.1 Tilt anglesFollowspot positions should be located to provide tilt angles as follows:In theatres and similar venues, the downward tilt angle should be within the range of 25 degrees to 55 de
