Getting the most out of LED sources
As the usage of LED lighting widens and its immense potential becomes more generally
recognized, the lighting industry needs to pay growing attention to the needs of
the end user and the quality of the visual environment.
The lighting industry has gradually developed, adopting widely accepted standards.
By adhering to these standards, the industry has guaranteed that users and their
environments are provided with the optimal solutions to ensure their physiological
and mental wellbeing.
The rapid development, however, of LED solutions and other advanced luminaires requires
that those designing and providing future lighting solutions pay much more attention
to the actual needs of the final consumer. Whether it is a municipality, which requires
outdoor lighting solutions or a developer who is building an office building and
is looking for interior lighting solutions, they should guarantee that they meets
the users' needs.
As the LED industry is still young and has not yet developed the appropriate standards,
there is a growing need to ensure that the use of LED lighting does not hinder visual
performance or cause visual discomfort.
LED is an excellent lighting source, but in order to maximize its advantages it
is necessary to use it properly and to integrate it with the right optical system.
The LED must be installed in the correct fixture to guarantee proper heat dissipation
and light distribution to create the optimum lighting environment.
It should also be noted that there are serious differences in the quality of different
LED solutions. Some low-cost LED lightning solutions don't last long and others
don't generate the required energy savings. In some of the cheaper LEDs sold in
the market, the light quality tends to deteriorate in a relatively short time.
Designing the right lighting environment can substantially improve worker productivity,
while a problematic lighting environment will yield the exact opposite.
Users of LED lighting installations should ensure that they will have the right
color rendering and unified glare rating (UGR) in order to guarantee that users
benefit from a visual environment that is specifically designed for their specific
