been towards low-profile units that can be hidden or designed
into the architecture so that the delivered light is the attraction,
not the fixture itself.”
Based on their small size and inherent controllability, LEDs
lend themselves perfectly to these designs.
For the consumer market, the continued trend will be
toward commoditization of LED-based lamps with more traditional aesthetics.
Campbell expects the commercial/industrial sector “to
begin looking for more future-proof designs where additional
functionality can be added at a later date, though this could
require some level of design for replaceable/interchangeable
drivers and light engines.
“Most users don’t want the bulky heatsink designs and optic
glare of many LED-based products available today,” he said.
Optical assembly is another major trend in fixture design.
In the past, reflectors and simple lensing were used to
diffuse the original source for visual comfort and optical performance. Now, a combination of compact total internal reflection
optics and extruded profile lensing are used to increase distribution and visual comfort in interior spaces. The result of these
technological advances is an opportunity for sophisticated performance enhancements and cost savings.
Lighting controls are another factor advancing fixture
design across all market segments.
“In the residential sector, it’s the rise of the ‘connected
home’ through [Internet of Things] platforms—e.g., the abil-
ity for consumers to control the security, HVAC, lighting and
entertainment functions within the home in an interconnected
way that allows for creation of a custom experience based on
personal preferences,” Veltri said. “In the commercial space,
it’s a trend toward low-voltage power and control, which sim-
plifies fixture design and installation, but, at the same time,
gives rise to deeper data analytics and greater control over the
building envelope. And in retail, it’s the opportunity for a dif-
ferent type of interaction between lighting and the consumer
through enhancement of color and connectedness but also
through the ability to understand consumer preferences on
a deeper level.”
Benya believes LED technology enables a range of high-
quality luminaires in the commercial sector, but that the cost
rises with some lighting systems—such as direct/indirect linear
pendant fixtures—and that reality currently stands as one of the
biggest obstacles to widespread adoption.
“Otherwise, LED has conquered the downlight, wall wash,
troffer and industrial lighting markets, but mostly with prod-
ucts that aren’t much different than their fluorescent and HID
ancestors,” Benya said. “For LEDs to make a complete trans-
formation of commercial lighting, we need new concepts that
embody much better glare control than the majority of com-
mercial LED lighting today, especially high-bay lighting.”
Benya believes the residential lighting market remains
“The replaceable LED lamp is successfully challenging
dedicated LED fixtures for a lot of the market and I believe
that energy codes will soon change to permit standard, screw-
