Photometry Training Workshop

Training Workshop: Radiometry, Photometry & Colorimetry

There are those who say that the science of measuring light is something of a dark art. We would respectfully disagree! From knowing your nits from your lumens, Pro-Lite’s Light Measurement & Photometry Training Workshop equips you with the knowledge to understand and express the performance of your products, and share specifications clearly and concisely throughout your supply chain. The full syllabus is detailed below.

Currently delivered remotely using the Microsoft Teams video conferencing platform, our 1 day workshop has been designed for both engineering and technical marketing personnel working with lighting and display products across many industries, including the architectural and street lighting, avionics, transportation and automotive sectors.

In addition to the standard workshop, Pro-Lite is happy to deliver customised training tailored to a client’s individual needs. This can be presented online, at Pro-Lite or at the client’s own facility. Examples of customised training we have presented include modules on the photometry of vehicle lighting, on retail lighting and on vehicle displays and interior lighting. Please contact Pro-lite to discuss your requirements.

The photometry workshop can be combined with our 1 day workshop on photobiological safety – click here for details.

Times: 09:00 – 17:00

Location: Online (via Teams)

Workshop Tutors: Robert Yeo, Russell Bailey, Leslie Lyons

Fee:

1.0      Basic concepts

  • The electromagnetic spectrum, human vision system, how LEDs work, reflectance and transmittance

 

2.0      Photopic vision & photometry

  • Understand how we perceive light – the photopic response of the eye and how our perception varies at low levels of light
  • Measurement metrics – luminous flux, luminous intensity, illuminance and luminance

 

3.0      Radiometry

  • Overview of radiometry – radiometric units, how these are analogous to the equivalent photometric units, applications (horticultural lighting, blue light and UV)

 

4.0      Tristimulus theory & colorimetry

  • Understand how we perceive colour – how human vision is based on the relative amounts of red, green and blue light that we see
  • Learn how to express the colour of a light source – chromaticity (colour space) diagrams, chromaticity coordinates (xy, uv, u’v’) and the “simplified” colour metrics of correlated colour temperature (CCT in Kelvin) and dominant wavelength

 

5.0      Measurement Equipment

  • Learn about the types of equipment used as well as the practicalities of measuring the amount and colour of light:
  • Integrating spheres for total flux measurements
  • Photometers for measuring illuminance and luminous intensity
  • Spot & imaging photometers for measuring the brightness of displays and signs
  • Measuring beam patterns using imaging photometers via projected illuminance measurements
  • Colorimeters for measuring colour and colour temperature of light sources
  • Spectroradiometers – being a more accurate type of photometer or colorimeter, as well as recording colour rendering
  • Goniophotometers for measuring the intensity or luminance of a light source or display as function of angle, and how to compute view angles and generate standard photometric files in .ies and .ldt formats Issues with measuring LEDs – be aware of the potential pitfalls

 

6.0      Special Topics

  • Display metrology – Luminance, Luminance uniformity, Contrast ratio and View angle
  • Flicker – what it is, how is it caused, why it’s a problem and how to measure it
  • Colour rendering – what it is, how it is measured and the differences between the latest IES TM-30-15 colour rendering metric and the original CIE 13.3 system, and how it levels the playing field for LED lighting
  • Photobiological safety – now that photobiological safety assessment in accordance with BS EN 62471 is a requirement of the updated luminaire standard BS EN 60598, we’ll revisit how to make photobiological safety measurements and to determine the appropriate risk group for your product
