Illumination Design


BRO's Illumination System Design tutorial gives participants the knowledge and skills they need to use ASAP and ReflectorCAD to design, model, and analyze general illumination systems.


Course Overview

Learn illumination and optics principles and how those principles are connected with illumination systems, including the design of luminaires, lightpipes, lightguides, headlights, taillights, and display systems. SAE and ECE standards are used in the design process with the use of the External Lighting Test Module (ELTM). Participants will access the BRO Light Source Library for a number of the sources used in the modeling. Theory and analytical methods are presented to provide the participants with the underlying design principles. Participants balance theory with hands-on experience by applying each lesson in a series of demonstrations and practice sessions.

Prerequisites*

  • Completion of BRO's Introductory ASAP Tutorial or equivalent knowledge and experience
  • Ability to build and view elementary systems with surface and edge-based entities
  • Ability to define and trace rays from various sources, and perform power, irradiance, and intensity calculations
  • Ability to comfortably write and run command scripts and macros
  • Basic knowledge of CAD software such as Rhinoceros® will prove useful during the course but is not essential
