Who should study this unit?

The aim of this module is to give engineers/project managers with little or no lighting design experience a better understanding of, and become confident in, the use of design methods for indoor lighting applications. Also to gain knowledge of the standards and guides used in lighting design and to better understand the Lighting designer/lighting specialist's offered solution.

The module contains not only sections on design, but also complimentary sections on lighting control systems as well as information and instruction with regard to lamp technologies.

The objective of this module is to enable informed choices of luminaires, lamps, lighting controls and designs in accordance with the needs of the end users.

Module Overview

• An outline of lighting: design for good lighting, criteria for design, factors affecting good lighting
• Glossary of terms used: design terms, lighting references, luminaire data sheets
• Introduction to lighting calculation methods: Point by Point method, Lumen method, basic design examples
• Energy efficient lighting sources: incandescent and tungsten halogen; fluorescent; high intensity discharge;
• high pressure mercury, metal halide, low and high pressure sodium; LEDs; energy efficiency design
• Lighting controls: basic electrical theory; dimming methods ; switching methods (relays, solid state) ; lighting control protocols and functions; daylight linking; occupancy sensing; time scheduling; load shedding
• Lighting control hardware
• Regulations and standards of lighting control
• Energy appraisal for design choices: design for minimum energy consumption

Learning outcomes:
Following successful completion of the module, users should be able to:

• outline the essential features necessary for an effective lighting design
• Explain the different technical terms used to measure the operational parameters of a lighting design such as: illuminance, luminance, luminous flux, luminous intensity, efficacy etc.
• Explain the operating principles of the main lamp forms for incandescent, low-pressure, high-pressure and solid state (LEDs) lamps, and have a good understanding of their luminous output, their efficacy and their suitability for various lighting tasks.
  (Included within the module is information on both the control equipment necessary to operate the various lamps, but also the control methods that can be used to operate lamps and ensure optical energy usage)
• Design suitable simple lighting schemes to ensure minimum energy consumption by both the point-to-point method of design (where applicable) and the lumen method of design.
