9、NA Design Guide for Application of Luminaire Symbols on Lighting Design Drawings Foreword This Design Guide provides a consistent guideline for creating a symbology for luminaires represented on drawings. It is intended for use by lighting design pro- fessionals, code authorities, contractors, and m

10、anu- facturers to express generalized luminaire types on printed and electronic design drawings. It replaces the previous edition, DG-3-94. However, this Guide is not intended to supersede the definitions and descriptions of the luminaire schedule or written specifications. The changes in this lates

11、t version include clarification on the use of fill in emergency luminaire symbols; the need for a complete project symbol list on every pro- ject; clarification of the meaning of a Horizontal Zero Line, a Directional Arrowhead, and a Directional Aiming Line; insertion point recommendations; sym- bol

12、 list clarifications; and editorial revisions including Annex A. 1.0 OBJECTIVE The objective of this Guide is to offer a set of symbols and modifiers that are standardized for use by the lighting design community in describing luminaires for lighting applications and design work. The intent is not t

13、o prescribe, but rather to describe a basic symbol set and establish certain guidelines that the lighting industry should use to make Computer Aided Design (CAD) application of lighting easier and more under- standable for the user. Through the use of a base symbol set and modifiers, a symbol can be

14、 created for any type of luminaire. The intent is to provide a set of building blocks, rather than a package of symbols that stand alone. Eventual adoption of these symbols as CAD blocks, which each level of the industry can apply to any luminaire, will allow all data pertaining to that luminaire to

15、 be automatically defined and inserted into a CAD lighting design drawing. It is not intended that this Guide replace or supercede a complete project symbol list tailored to the specific project. All projects should have a project-specific symbol list limited to only those symbols actually used on t

16、he project. 2.0 CRITERIA The symbol lists show a Base Luminaire Symbol Set to describe lighting sources and two types of modi- fiers, basic and extended. The base symbol should represent the approximate shape of the luminaire as shown in Figure 1. If information about mounting, optic orientation, or

17、 an emergency designation is desired, the Basic Luminaire Modifiers shown in the symbol list of Figure 2 shall be used. These Basic Modifiers shall 1 IESNA DG-3-00 Luminaire:(drawn to approximate shape and to scaleor large enough for clarity) Luminaire: Strip type(length drawn to scale) Linear sourc

Symbols shown comprise the base luminaire symbol set. be restricted to conveying only mounting, optic

19、orien- tation, or emergency information. If further information or refinements to the description of the luminaire being applied are desired, the Extended Luminaire Symbol Modifiers in the symbol list of Figure 3 should be used. However, there are no conventions or restrictions placed on the use of

20、the Extended Modifiers. If the distinction between recessed and surface mounting is to be shown, then all recessed luminaires shall use the base symbol shape and the single cross hatch line modifier. To identify a luminaire that provides emergency illu- mination, it shall be shown filled in (see the

21、 “emer- gency” portion of Figure 2 and the discussion of emergency luminaires in Section 3.3). The fill shall be as complete as possible without obscuring the modi- fiers (if used). Single-line symbols shall have a filled element added to indicate an emergency application. To establish criteria for

22、roadway luminaires, the base symbol shall be that of a point source and it shall have modifiers consisting of an arm and pole. Symbols for area luminaires having light distributions intended for roadway use may be modified at the discretion of the user to be round, square, rectangular, or cobra-head

23、 style. Many variations of “local standard” symbols are used for roadway projects. Symbols shall be defined clearly in the project symbol list. 3.0 APPLICATION 3.1 Rendering Luminaire Symbols Clearly in Drawings The luminaire symbols in the symbol lists of Figure 1, Figure 2, and Figure 3 should be

24、drawn to scale whenever possible in their appropriate proportions, orientation, and shape (see Figure 4). When a sym- bol drawn to scale is too small to be easily read (when reproduced), the symbol may be enlarged to an appropriate size while maintaining proportion and ori- entation. Luminaire symbo

25、ls shall be drawn in a line weight and/or color to make them stand out on reproduced lighting and electrical drawings. The entire symbol shall be drawn at a consistent line weight. Symbols with double lines shall be drawn with lines sufficiently separated to be recognized as double lines on reproduc

26、ed drawings. A Luminaire Identifier, referring to the luminaire description and type in the luminaire schedule, should accompany each luminaire symbol on a drawing. Identifiers shall be drawn to a legible size either on the symbol or near it, to the lower right whenever possi- ble (see Figure 3). 3.

27、2 Applying Directional and Orientation Modifiers With directional luminaires, the addition of optic orien- tation modifiers should be used when they help to clarify the intended orientation. The orientation modi- fiers are the “Horizontal Zero Line,” the “Directional Arrowhead,” and the “Directional

28、 Aiming Line” (see Figure 2). These modifiers may be omitted if the directional intent is not lost. Care must be exercised to not cause confusion between aiming lines and architectural background elements. The optic orienta- tion modifiers have specific meanings, and the users of these modifiers mus

29、t be aware of the photometry of the luminaire and its intended application. The Horizontal Zero Line indicates the zero degree horizontal plane direction of the luminaires photomet- ric data. It shall be drawn from the photometric center with the length as long as necessary for clarity. It may be co

30、ntained within the symbol, if clear. The Directional Arrowhead indicates the primary lumen orientation of the luminaire hereby defined as the horizontal zone(s) containing the most lumens. Typical application would be for wall washers and luminaires with an asymmetric distribution. Multiple arrowhea

31、ds should be used to indicate multiple zones of maximum lumen output. The Directional Arrowhead may be combined with the Horizontal Zero Line if the zero degree horizontal plane and the pri- mary lumen orientation coincide. The Directional Aiming Line shall be used if the actual aiming point is inte

32、nded to be shown. The Aiming Line shall be drawn from the luminaire pho- tometric center and shall extend to a small filled cir- cle at the aiming point. Directional Aiming Lines are commonly used for outdoor accent lighting or for sports lighting. 3.3 Drawing Exit Signs and Emergency Luminaires Exi

33、t signs shall be drawn as shown with one or two sides filled in indicating a single- or double-faced sign and in which direction the faces are oriented. If it is desired to indicate face arrows, an arrow shall be placed next to either (or both) faces and shall indicate which direction the arrow is p

34、ointing (see Figure 1). 2 IESNA DG-3-003 IESNA DG-3-00 The filled-in portion of emergency luminaires may have to be reduced in order to minimize conflicts with other modifiers such as those for recessed or pendant mount. Optionally, the fill may be done at a 50 percent (or appropriate) screen to all

35、ow the overlapping mod- ifiers to show through. 3.4 Drawing Electrical Symbols; Describing Mounting Height Electrical symbols such as junction boxes, switches, and wiring may be drawn on (or adjacent to) luminaire symbols. The mounting height modifier (see Figure 3) shall be used to indicate the hei

36、ght to the light center of the luminaire (or to the bottom of the luminaire if it is sus- pended). For interior spaces, the height shall be above finished floor (AFF). For exterior areas, the height shall be above finished grade. 4.0 COMPUTER REPRESENTATION When using luminaire symbols with a CAD sy

37、stem, each symbol should be treated as a block, allowing for attributes such as the Luminaire Identifier (dis- cussed in Section 3.1). When using luminaire symbols with lighting design software, the insertion point for the symbol block should correspond to the photometric center. If not inserted at

38、the photometric center, an offset from the insertion point to the photometric center should be electronically incorporated into the symbol structure.4 IESNA DG-3-00 Recessed Wall-mounted Suspended: Pendant, chain, stem, or cable hung Pole-mounted with arm Pole-mounted on top Ground- or floor-mounted
