Parameters of the IESNA LM-63 Viewer

From General tab, you can set general information about the luminaire.

From Tilt tab, you can set information about lamp position and its influence.

• If selecting None, tilt has no influence on the lamp output.

• If selecting Include, the lamp output varies as a function of the luminaire tilt angle.

  You can Add Tilt Angle or Delete Tilt Angle .

  In the Lamp to luminaire geometry box, you can select the lamp position in the luminaire.

From Miscellaneous tab, you can set photometric parameters about the luminaire.

• In Number of Lamps box, you can type the number of lamps value in the luminaire.

• In Lumen per lamp box, you can type the power value of the lamp.

  This value is obtained from the manufacturer's technical data. It does not represent the lumens emitted by the test lamp.

• In Candela Multiplier box, you can type the multiplying factor to be applied to all Candela values in the photometric data file.

• In Input Watts box, you can type the consumption value of the lamp.

• In Ballast factor box, you can type the Ballast factor value.

• In Futur Use / Ballast lamp photometric factor box, you can type the future use of the Ballast lamp photometric factor value.

• In the Photometry Type box, you can read the photometric type.

  Type C is most of the time used for architecture and roadway. The polar axis coincide with the vertical axis of the luminaire, and the 0-180° plane contains the luminaire major axis, the length. Type B is used for adjustable outdoor area and sports lighting luminaire. The polar axis of the luminaire coincide with the minor axis, the width of the luminaire, and the 0-180 degree photometric plane coincides with the vertical axis of the luminaire. Type A, not yet available, is used for automotive headlights. The polar axis coincide with the major axis, the length of the luminaire., and the 0-180 photometric plane coincide with the vertical axis of the luminaire.

From Dimensions tab, you can set parameters about luminaire dimensions.

Negative and null parameters give information about the shape.

• In Luminous dimensions box, you can change luminous opening dimensions. In Width box, you can type the distance value in feet across the luminous opening of the luminaire as measured along the 90-270 axis. In Length box, you can type the distance value across the luminous opening of the luminaire as measured along the 0-180 axis. In Height box, you can type the distance value across the luminous opening of the luminaire as measured along the vertical axis.

• In Units box, you can select Feet to use English units or Meters to use metric units.

• In Luminous Shape box, you can read codes about luminous opening shapes (IESNA LM-63-95):

From Symmetry tab, you can read parameters about luminaire symmetry.

It is possible to choose symmetry properties when creating a new IES file.

From Data tab, you can set intensity data given in Candela for each sample.

You can Add Vertical Angle , Add Horizontal Angle , Delete Vertical Angle , Delete Horizontal Angle .

In Result tab, you can read maximum values for IES files.

Global Maximum is given with its position and Local Maximum for a given horizontal angle. The IESNA LM-63 viewer gives you its position. Measured Flux is the result of all measured data. It is the equivalent of the total flux from the XMP.

From Luminance tab, you can change luminance values in cd/m² or cd/ft² for each sample.

From Edition tab, you can change options for printing the photometric report.
