Gardco
Fascia Wash : The Fascia Wash is a wall mounted
luminaire designed to light large wall surfaces
as evenly as possible with as wide a spacing as
possible. The luminaire offers an alternative to
floodlighting which requires luminaires mounted
away from the building. A barrel style Fresnel lens
was used in conjunction with internal reflector
optics to produce the desired performance. The luminaire
stands only 14" off of the wall surface yet achieves
a mounting height of 20' and a spacing of 40'.

Genesis Horn Strobe Fire Alarm : LTI designed
a patented reflector/refractor optical system using
a white diffuse reflector that enabled a completely
new product to be designed with a priority put on
the product's appearance. This product is the first
to transform the utilitarian devices which have
historically populated this industry into a component
which compliments architecture. The unique optical
system not only allowed for a lower profile product
it also produced a better light pattern allowing
it to be safely seen from more viewing angles than
other devices on the market.

Type
III and Type V Glass Refractor Design : Two
new glass refractors were designed for an outdoor
lighting manufacturer to add to their existing range
of optical systems. The new refractors needed to
provide improved spacing performance over competitive
products based on illuminance and roadway luminance
criteria. To design the new refractors, LTI developed
specialized refractor design tools so that various
prism configurations could be quickly created and
analyzed in Photopia. The optimization of such a
complex part would not have been possible without
the ability to automatically generate the prism
profiles for the inner and outer surfaces.
LED
Headlamp Design : A new reflector was designed
for a hybrid halogen / LED headlamp design
for the leading
outdoor equipment manufacturer Black Diamond.
The design improves upon previous products
by using a double faceted reflector to produce
an artifact free medium flood beam pattern.
The round beam shape is maintained despite
a portion of the reflector being cutout to
accommodate up to 4 LEDs.

Type
III and Type V Roadway Cutoff Reflectors : Two
new reflectors were designed for an outdoor lighting
manufacturer to add to their existing range of optical
systems. The new reflectors needed to provide an
IES Cutoff distribution while matching or improving
upon the spacing performance of their existing products
based on illuminance, roadway luminance and veiling
luminance criteria. The new reflectors provided
this as well as improvements in the appearance of
the light pattern and the overall amount of light
on the roadway. The designs were optimized to provide
the best performance with the smallest number of
assembled parts ensuring that the manufacturing
costs were minimized.
LED
Refractor Design : New refractor designs were
created to maximize visibility for LED-based mobile
signage. Special design characteristics were added
to protect lens elements from the environment and
implement a smooth exterior lens face to minimize
the collection of debris. This new design exceeded
all previous performance marks.
