Many commonly-occurring lighting applications are mounted on a tall pole. Some are cantilevered, others are pole-top.
- For cantilevered fixtures, omit the pole, and focus the analysis just on the fixture:
- For post-top applications, include part of the pole, but cut it approximately to a length three times height of the fixture:
Geometry
- Construct an enclosure around the light, and center it horizontally within the enclosure. The size of the enclosure should be based on the size of the device, as shown below.
- The side view is shown on the left; the front view is shown on the right:
Note: Air enters from the bottom and exits through the top. For more about the ideal flow profile and troubleshooting...
Boundary Conditions
- To define openings at the top and bottom, assign Static Gage Pressure = 0 to both surfaces
- Bottom face (inlet): Static Temperature = ambient temperature
- Heat loading is specific to the lighting type. Click for LED. Click for fluorescent.
