IES Road Report LCS Graph

The LCS Graph tab displays a shaded graphical representation of the Luminaire Classification System zonal luminaire lumens, % lamp lumens or % luminaire lumens. By default, the graph displays % lamp lumens and  is scaled to the maximum LCS percentage for the specific luminaire. Each ring in the polar graph represents a 25% increment of the maximum.

The graphical plot represents a section view looking at the luminaire in elevation. The lower right quadrant of the graph represents the Front - Downlight components (Street Side); the lower left quadrant of the graph represents the Back- Downlight components (House Side) and the upper hemispherical section represents the uplight component. The shaded "pie wedge" inside each zonal section represents the percent of zonal lumens that exists in that specific zone.

When comparing multiple photometric files, it may be useful to set the scale equal to Total Lamp Lumens or a user defined Lumens value instead.

The display Colors, Scale and Display Type may be customized by the user on a temporary basis or permanently in the Settings dialog.

Front - This section specifies the shading colors to be applied to the Front Downlight zones: Low, Medium, High and Very High. By default, green hues are specified.

Back- This section specifies the shading colors to be applied to the Back Downlight zones: Low, Medium, High and Very High. By default, blue hues are specified.

Uplight (Front + Back)- This section specifies the shading colors to be applied to the Front and Back Uplight zones: Low and High. By default, red hues are specified.

Scaling - This section determines the percentage used to scale the graph. By default, the Maximum LCS is applied (18% in the example above); however, the total lamp lumens or a user defined lumen value may be used instead. Note: If the user defined lumens specified are less than the LCS lumens, the wedges displayed may exceed the boundaries of the graph. This option is useful when comparing multiple luminaires side by side.

Display Type - This section determines whether to generate the graph based on % Lamp Lumens, % Luminaire Lumens or Luminaire Lumens. The default selection is Luminaire Lumens. If % Luminaire Lumens or % Lamp Lumens is selected, the graph will look the same, only the values will change.

Note: If user defined lumens are selected as the Scaling basis, the only Display Type allowed is Luminaire Lumens as well.

LCS Values - Below the LCS Graph, the LCS values will be displayed based on the selected Display Type: % Lamp Lumens, % Luminaire Lumens or Luminaire Lumens.
