Philips LED Luminaires - Manual (Page 2)

Architectural lighting plays a central role in the way people feel
about their living environment. Employed imaginatively, it can
create a poetry of daily life by elevating the mundane and banal
through a reinterpretation of everyday city objects and buildings.
Thanks to Philips Lighting’s ability to generate
new experiences and emotions, we can help shape
an inclusive, socially dynamic city. A place where
people can feel part of a shared beauty that
transcends their daily existence and links them to
each other, to their past, and to an enlightened
quality of life.
More and more, the expression of a town or city’s
architecture will come from its lighting rather than
from its structure. If buildings are the monumental
canvases on which lighting designers paint their
artistic vision of urban renewal, then light has
helped to deliver their most telling brushstrokes.
And now Philips is expanding the palette with
a host of light-emitting diode ( L E D ) lighting
solutions, a new concept based on cutting-edge
L E D technology that will enable lighting designers
to realize beauty with light, turning their vision
into reality. Opening up a virtually infinite range
of effects, Philips L E D luminaires are versatile
enough to allow light to fill or underline, graze or
pinpoint, mark or blend. With a choice of up to five
colors, including white, they give free rein to the
architect’s and designer’s creativity.
How it works
The basic structure of a L E D consists of a dye or a
light-emitting semiconductor material, a lead frame
in which the dye is placed, and the encapsulation
epoxy that surrounds and protects the dye.
The semiconductor crystal, which is laboratory-
grown, emits light initiated by a forward current
within the L E D . The light color varies depending
on the nature and composition of the crystal used.
Performance levels are continuing to rise
dramatically. New packages are increasing the
cooling efficiency for the dye, thus permitting
higher current levels and hence higher light output.
