Abstract
The lighting industry is driven to provide light sources and lighting
systems that, when properly applied, will produce a suitable
luminous environment in which to perform a specified task. Tasks
may include everything from office work, manufacturing and
inspection to viewing priceless art objects, selecting the right chair
for your living room, and deciding which produce item to select for
tonight's dinner. While energy efficiency is a major consideration
in any new lighting system design, the sacrifice of lighting quality
may cost more in terms of lost productivity and user dissatisfaction
than can ever be saved on that monthly energy bill.
During the past several years, many new light sources have been
developed and introduced. These product introductions have not
been limited to anyone lamp type, but instead may be found in filament,
fluorescent and high intensity discharge lamp families. Manufacturers of light sources have two basic goals for new product
development. These goals are high efficiency lighting and improved
color rendering properties. High efficiency lighting may take the
form of either increasing lamp efficiency (lumens of light delivered
per watt of power consumed) or decreasing lamp size, thus making
a more easily controlled light source that places light where it is
needed. The manufacturer's second goal is to produce lamps that
render colors accurately while maintaining high efficiency. This
paper will discuss new introductions in light sources and lighting
systems and how they may impact the design of luminous environments
of the future.
