When a ray strikes a refractor surface from the "outside" from the air, for example , it is partially reflected and refracted according to Fresnel's Equations and Snell's Law of Refraction, respectively. Light is also absorbed within the material according to the path length within the material and the material's extinction coefficient.

Once rays have entered into a refractor material such as glass, Photopia searches for intersections with other refractor surfaces on all refractor layers in the model. Once an intersection is found, the ray is either partially internally reflected and partially refracted out or it is Totally Internally Reflected TIR back into the material, depending on the incidence angle.

Clear lenses can be modeled with either Transmissive or Refractive surfaces. Transmissive surfaces will result in a faster analysis. If the lens is curved, then only the inside surface of the true lens shape should be modeled if making it a Transmissive surface.

If the curvature and thickness of the clear lens are such that there might be some refractive effects, then it should be modeled as a Refractor using its true geometry and thickness. For example, a flat sheet of translucent white plastic can be rotated within the plane of the material and the scattering of the incident light will be unaffected. If a material such as a plastic lens with extruded linear prisms was rotated there would be a significant difference between the scattered light patterns.

The effects of the prisms on the light are different depending on whether the light strikes the prisms from within a plane that is parallel, perpendicular or some other orientation to them. Such materials are referred to as anisotropic. A perforated material is isotropic if it has round holes in a regular pattern, but it would be anisotropic of it contained linear slots. When a CAD model is constructed as a solid, every part has a thickness.

Thus, if a prismatic lens or white diffuser material is drawn as a solid, it will be constructed with the thickness of the physical part. When this model is exported to Photopia via a STL file it imports as a mesh of polygons that cover the surface of the original solid model.

If a transmissive material is assigned to the mesh that models this lens, then a ray will encounter 2 surfaces when passing through the material model.

To avoid this problem, we have made special versions of the transmissive materials where the second surface is ignored in such a case. These are the Solid Model versions of the transmissive materials and they should be used when the CAD model was constructed as a solid model.

Note however, that the Solid Model versions of the materials only produce the proper effect if all of the surfaces of the lens model are oriented so that their "front" side is facing to the outside of the part.

Thus, if the part is on a layer with a color of white, then the part should be rendered as white from all points of view when viewed in the Show Surface Orientation model in Photopia. This is important because the way that the Solid Model materials work is to have the reaction on the "back" side of the material be perfectly transmissive.

So when the ray encounters the second surface of a lens model, it strikes the "back" side and is allowed to pass directly through with no losses or scattering.

One significant consequence of this is that it prohibits or at least limits the use of materials with different properties on each side. But in the case of Solid Model materials, the "back" side must be set to be perfectly clear, so this flexibility is lost. This is why all of the Solid Model materials in the library are for materials that are the same or mostly the same on both sides. If you have a need for another material to be made into a Solid Model material, then contact us about making a new material for you.

It is possible to make Solid Model materials for materials that are different on each side as long as light is only incident onto one side of the lens in the luminaire model. This is for materials which scatter light within their volume, usually via pigment or diffusion particles. These are a special class of Refractive materials, and as such require the General Refractor Module or Photopia Premium.

Volumetric scattering can also be used along with spectral material properties to model phosphor particles suspended in a clear material. Photopia uses a specific XML formatted file for defining the material properties.

Photopia accounts for the extinction coefficient within the clear base material, the scattering coefficient likelihood to scatter , the absorption of the scatter reaction, as well as the distribution and energy conversion of the scatter reaction. Full details are provided in this Volumetric Scattering Documentation.

With Photopia , we introduced the ability to set spectral properties for materials. For spectral materials to function, a raytrace must be set as an SPD raytrace. You must also have appropriate. Each spectral material must have a. This is an XML based file that tells Photopia what files contain the data for the given material. The file lists a scale value and then the name of an spdmatrix file for each incident angle.

The format is the same for reflective or transmissive materials. This file can describe something as simple as a paint color or color filter, or it can describe the complex behavior of a phosphor or other wavelength conversion material. Since Photopia is a probabilistic based raytracing program, the results get more accurate as more rays are traced. The number of rays that are required to obtain accurate results depends on the level of "resolution" you have specified, in other words, the level of detail in the results.

You can view the results such as the candela polar plot and the illuminance plane shaded plot and watch as they vary around their final values with each update as the raytrace proceeds. The least detailed result is the luminaire efficiency LOR. This is a single number that represents how many lumens exit the luminaire compared to how many lumens were generated by the lamps. The exact direction of the exiting lumens is not critical when determining the efficiency. Thus, you can see that the efficiency changes very little after the first update of the results during the raytrace.

The candela distribution requires much more detail to be resolved since Photopia needs to determine exactly how many lumens belong in all of the angular zones of the distribution.

The more angles that are specified in the distribution, the smaller the angular zones and thus the more rays it takes to determine the correct proportions of lumens in all zones. The most level of detail is generally required for the illuminance planes.

Whereas the angular zones in the candela distribution might be separated by 2. With this general understanding, we make the following recommendations for the Raytrace and Photometric Output settings.

Keep in mind that these are only general recommendations and you can vary these values as long as you understand the consequences. This options can be left off for most other lamp types. All other raytrace settings can generally be left at their default values. This allows the use of Photopia for a wide range of applications from general lighting to agriculture and radiant heating. Set this to the units you wish to see for your input and output. This is an XML format file, using a pre-release version of a future IES file format that has been expanded to support luminaire color data.

The data in this file can most easily be viewed by opening it in Excel, using a reference style sheet file that tells Excel how to format the data. The style sheet file is named "iesxToText. Put a copy of this file in the same folder as your IESX file. At the "Import XML The first row in the spreadsheet will include the column labels. If you chose the "Power distribution raytrace" option in Photopia, then the full spectral values will be listed for each angle in the beam at the nm resolution you specified.

Select the Options button on the file dialog and use the following settings:. When importing into Photopia you can use the Shift and Ctrl keys to select the entire range of parts you want to import. Photopia will assign layer names for each part using the filenames. Inside of Photopia, select the reflector that you want to export.

On the left side of the screen there is a section titled "Exporting Curve Profile. Name the drawing, and select DXF from the drop down menu. Select any plane. Select the DXF file that you just exported from Photopia. You can then select Next for the Layer Mapping screen. Then select finish. AutoCAD and later versions work such that using the DXFIN command opens a new drawing window instead of importing the geometry directly into the open drawing.

The following lists two ways to import lamp models into your existing drawing:. With Photopia 3. Photopia includes the same meshing options that are available in AutoCAD plus some additional options.

If you have the Triangulation Setting Style set to "Use the Facet Resolution for triangulation settings," then change the Facet Resolution setting to whatever value you require. If you choose "Use triangulation settings" as the Triangulation Setting Style, then you can set the following 3 parameters listed in the dialog to meet your requirements.

Before Photopia 3. This command was widely used to convert solids within AutoCAD to faces. Follow these directions to install and use the command:. However, since Photopia V3. Photopia includes the same meshing options that were previously available in AutoCAD plus some additional options.

AutoCAD has a command line interface similar to Photopia. The following are some basic tools in AutoCAD, with their command alias in square brackets. There are 2 options for importing models from Inventor into Photopia. The first option is preferred. The NURBS surfaces can then be easily converted to polygon meshed based models for use in Photopia, but before they are converted make sure that the parts in the model that use different material finishes are separated onto different layers.

In this case, you must define a new layer for each part with a different surface finish and then move the parts to their appropriate layer. The steps for this are listed below:. Rhino contains some very good facilities for creating meshed surface models or polygon based surface models from NURBS surfaces or solids.

The easiest method is to convert them at the time the DXF file is written. Photopia 2. Exporting from the assembly is preferred since the assembly drawing includes the information that shows how each part is translated with respect to each other. These relationships are retained when the parts are exported from the assembly model. Solid Edge does not, however, allow STL parts to be exported from the assembly model.

Therefore, each part needs to be exported from the individual part files. The coordinates of each part are therefore relative to their own coordinate systems.

If each part uses an origin 0,0,0 set to some arbitrary reference point on that part, then the parts will not import into Photopia with their correct relative positions. For a lighting fixture, the most logical common origin is the center of the lamp, or lamps, if there are several.

If this convention is used, then all parts will import into Photopia in their proper relative positions. The following directions were taken from Creo Parametric Directions may vary for other versions, but will be similar. You can find some general instructions for how to export STL files from the following web site: www. If your model is built from solids bodies , then you can save the parts to STL files.

Each part of your assembly needs to be exported to its own STL file. This is because Photopia will put each STL file onto is own layer and materials are assigned to each layer in Photopia. Select the option to save to an STL file from the File menu. We recommend the following export options:. If there is an equivalent method for creating meshes, then that is preferred by Photopia. You need to separate different parts onto different levels because Photopia assigns luminaire materials on a per "layer" basis.

The following information may be helpful to those using Microstation to create 3D models for Photopia. To convert the parametric solids from Mechanical Desktop into polyface meshes, which Photopia accepts, follow these steps:. Having the correct Photometric Settings is critical to obtaining accurate results from Photopia.

When you send a product for testing, the laboratory often determines the correct photometric angles, but when you are running Photopia it is something you must always be aware of.
