Workshop: Photobiological Safety of Lamps and Lighting

Light: the fuel of life

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.

The Tutor

Leslie Lyons, Technical Support Manager at Bentham Instruments Ltd, Reading UK, has an MPhys degree and has worked in optics and photonics for over twelve years.  Highly experienced in his field, Lyons has been actively involved in photobiological safety standards development and is a member of BSI and IEC committees TC76, "Optical Radiation and Laser Safety" and BSI CH/172/6, "Opthalmic instruments" and sits on the photobiological safety panel of IEC TC34.
