CANCELLED - The Light Year Public Lecture Series - The Light from Lighthouses: Past, Present and Future

10th March 2014, 18:15 to 19:15, Kingsley Barrett Room, Calman Learning Centre, Durham University, South Road, Mr Malcolm Nicholson, Trinity House


This lecture will chart the development of light sources used within lighthouse lenses. Setting the scene with how light interacts with the eye and a brief description of the units involved, the lectures starts with the Paraffin Vapour Burner (PVB) and how the lenses were focussed at the Chance Bros. Factory in Birmingham. Introducing the electric light source and the British Standard Lighthouse Lamps the lecture will move on to how the Trinity House engineers worked with lens makers to achieve longer ranges with smaller lenses. Moving on to modern light sources and the challenges of installing and measuring lighthouse light intensities the lecture closes with the very latest developments in LED technology and their use in classical lighthouse lenses.
