handbook is that of a general lighting textbook
for students. “While there are many good lighting
textbooks around, there is no book that brings all of
this information together in a single place,” explains
Raynham.
Light and vision
The handbook is divided into three main sections –
fundamentals, technology, and lighting applications.
The contents page provides detailed sub-sections for
each of the three, so that a particular requirement can
be easily found.
Fundamentals focuses on information about light
and vision. This section covers photometry and
explains the terminology commonly used in lighting
design. As such, it will be a valuable resource for
those who are involved in basic lighting designs
using software to carry out calculations without
necessarily understanding the terminology used in
the software.
