Acrylic plastics are among the most important of the new materials being used by lighting engineers in the construction of fittings.
Available in many varieties, their optical, thermal, and mechanical properties are reviewed and related to the use of the material in lighting equipment.
Fabrication methods for moulding and shaping the material must be adapted to its characteristics, and details are given of the more widely used techniques, including shaping, high pressure moulding, machining, and jointing.
The developing use of the material in selected fields of lighting practice is outlined, and fittings typical of modern practice described.
