Photobiological Safety Training Workshop

Photobiological Safety Training Workshop

Workshop 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 optial radiation directive, a well defined legal framework is now in place.

The workshop has been designed to provide an overview of photobiology, how standards are implemented, to what they apply and the impact of legislation upon business.

Who Should Attend?

This workshop 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.

Your Tutor

Leslie Lyons has a wealth of experience in optical radiation measurements, having been involved in the development of photobiological safety standards. Leslie serves on the BSI technical committees EPL/76 «Optical radiation safety and laser equipment» & CH/172/6 «Ophthalmic instruments». He also serves on IEC TC 76 «Optical radiation safety and laser equipment» & IEC TC 34 WG6 «Photobiological safety».

Workshop Syllabus

The training will be presented remotely via Microsoft Teams
 
 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.
  
§ 1.0Theory 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.
§ 2.0Practical 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.
