Photobiological Safety of Lamps, LEDs & Lighting Workshop

Photobiological Safety

Course Overview

The reappraisal of the place of LEDs in safety standards has had a significant impact on the process of bringing to market products containing LEDs or any other non-laser source of optical radiation, whether the emission of light be the primary purpose of the product or not. From CE marking to consideration of employee safety under the auspices of the EU artificial optical radiation directive, a well defined legal framework is now in place. The course has been designed to provide an overview of photobiology, how standards such as EN 62471 are implemented, to what they apply and the impact of legislation upon business.

Who Should Attend?

This course is aimed at those working for manufacturers of lamps, luminaires (or any product containing non-coherent sources of optical radiation), laboratory managers, laboratory engineers, regulatory affairs managers, quality managers and any individuals who are keen to learn how photobiological safety standards may affect their business.

New for 2018

For 2018, we've scheduled the Photobiological Safety training module as the third day following our two day Photometry and Light Measurement Training module. This means that delegates can (if they wish) attend the Light Measurement Training on days 1 & 2, which serves as a foundation for the Photobiological Safety Training held on the third day.

Course Syllabus

Photobiological Safety – Theory & Practical Measurements

This eight hour module reviews the hazards to our skin and eyes from artificial optical radiation as well as the legal framework that applies to employers and manufacturers of lighting products. The measurements and calculations required by EN 62471 to assess the photobiological hazard associated with a light source will be presented and the steps required to assign the product to one of the four “risk groups” reviewed.

Theory of Photobiological Safety

  • The optical and thermal hazards that light from 200-3000nm presents to our skin and eyes.
  • The legal framework for photobiological safety as it applies to employers and to manufacturers of lighting products.
  • Simplified analysis for white LED-based luminaires – the blue light hazard.

Practical Measurements for Photobiological Safety Calculations

  • Spectroradiometric measurements of irradiance and radiance.
  • Applying the EN 62471 hazard weighting functions.
  • Special test conditions for GLS sources.
  • Special test conditions for recessed light sources – sources used with lenses or reflectors – and the need to establish the apparent source size and location.
  • Calculation of the EN 62471 risk group.
  • Labelling and supporting documentation requirements for the four risk groups.
  • Testing the “worst case” light output.
