Training aim

To give an introduction to the participants to basic lighting terms and how these interact with the lighting design process and the lamps on the market at the moment.

Learning objectives

  • To understand the difference between luminance and illuminance and  its importance in lighting design and evaulation.
  • To distinguish between the colour parameters of colour temperature and colour rendering and identify how these relate to the light electromagnetic spectrum and lighting design.
  • To be able to evaluate all the current lamps available at the moment. To assess how these interact with luminance/illuminance and colour criteria and to match suitable lamps with particular applications.

Course outline

Firstly, brightness criteria of luminous flux, efficacy, luminous intensity, illuminance and luminance are all explained. The lighting spectrum is introduced and  the colour concepts of colour temperature and colour rendering explained.

All the lamps available at the moment are then introduced and demonstrated as they are being discussed.

Finally there is a general introduction into how the emphasis in lighting design is changing  from illuminance to luminance and why.
