TEXTBOOK CASE

摘要

Road lighting is a specialised and fairly complex field of lighting. There are many practitioners, but not so many who have a real grasp of some of the finer points relating to visual performance and visual comfort. This is a really comprehensive book dealing with every aspect of the subject well. It is a very theoretical, research-driven text that deals with the facts, but which does not offer so much in the way of personal opinions and recommendations. This may be because the author has been involved in the writing of many of the relevant CIE standards. From a UK perspective, it is good to see that a lot of the research from Peter Raynham, Steve Fotios, Teresa Goodman and so on has been recognised. It is, however, disappointing that there are a number of omissions, in particular references to our British Standard BS5489-1: 2013 as well as to the numerous ILP reports which are essential tools for the UK road lighting professional. In particular the guidance on the use of mesopic vision in PLG-03 Lighting for subsidiary roads would have been a useful addition to the references.
