Photopia Advanced Tutorial – Designing a Linear Fluorescent Reflector with the Parametric Optical Design Tools
This project will create an open 4-lamp T8 fluorescent luminaire with a reflector that produces a medium wide beam with a spacing criterion (S.C.) between 1.3 and 1.5. S.C. is the ratio of the spacing to the mounting height at which the illuminance half way between two luminaires equals the value directly underneath the luminaire. It therefore indicates […]
Photopia Advanced Tutorial – Designing a Linear Fluorescent Reflector with the Parametric Optical Design Tools
the Parametric Optical Design Tools This design utilizes a feature in the PODT module to link together 2D profiles to create 3D surfaces beyond the revolved and extruded surfaces of the basic tools. In order to get the most from this tutorial, it is best if you are already familiar with the basic concepts of the PODT […]
Photopia Advanced Tutorial – Designing a Medium Flood Beam with an LED Source
This tutorial demonstrates designing a reflector around an LED to create a medium flood beam, and using an anisotropic material. It is a good idea to complete the beginner tutorials before attempting this advanced tutorial, since many of the more basic functions and concepts are not explained in this tutorial. Import the Lamp 1. Start a new […]
Photopia Advanced Tutorial – Designing a Wall Wash Reflector with a Fluorescent Source
This tutorial demonstrates the design theory of an asymmetric wall wash reflector. The goal is to create a reflector within realistic size constraints that achieves a smooth illuminance onto a wall. It is a good idea to complete the beginner tutorials before attempting this advanced tutorial, since many of the more basic functions and concepts are not explained […]
Photopia Advanced Tutorial – Analyze a Skylight Using the Sun & Sky Dome Models
Photopia includes sun and sky dome “lamp” models for use in modeling daylight collection devices. These models are based on the IESNA RP-21 daylight equations that model the absolute illuminance from the sun (solar disk) at various altitude angles and the sky for various sky conditions and solar altitude angles. The sky domes include variable luminance values […]
Photopia Advanced Tutorial – Designing Type V LED Roadway Lenses
This tutorial demonstrates the design process for a smooth roadway lens designed around an LED source, to be arrayed in a roadway luminaire. The LED’s are to be arrayed 20mm x 20mm, with 60 LED’s total. The tutorial covers both round and square Type V IES classification designs, and briefly explains how other types can also be created […]
Photopia Advanced Tutorial – Design an Extruded Lens
This tutorial demonstrates designing an extruded lens around a fluorescent source by utilizing Photopia’s Parametric Lens Design Tool. It is a good idea to complete the beginner tutorials before attempting this advanced tutorial, since many of the more basic functions and concepts are not explained in this tutorial. The lens design parameters for this tutorial will be […]
Photopia Advanced Tutorial – Imaging an Optic
This tutorial demonstrates imaging a strip of LED’s to “look” back into the optic and see how the optic would appear, rather than analyzing output. In many situations, the aesthetics of a light fixture is important in addition to its output. Using an imaging lens onto an illuminance plane, we can see what the light fixture looks […]
Photopia Advanced Tutorial – Designing a Collimator for an LED Source
This tutorial demonstrates importing an LED with integrated optics and designing a collimator lens around it, utilizing both the reflector and lens design tools. It is a good idea to complete the beginner tutorials before attempting this advanced tutorial, since many of the more basic functions and concepts are not explained in this tutorial. The collimator design parameters […]
