Bridgelux has announced the Outdoor Lighting
Module (OLM) LED-based product family meant to accelerate the
development cycle for manufacturers working on outdoor-lighting
products. Bridgelux said that the weather-tight module with integrated
optics can reduce solid-state lighting (SSL) development time by three
to six months and cut $100,000 in R&D expenses.
With the OLM, Bridgelux is targeting roadway, parking, industrial,
and other outdoor applications. Each module integrates two Bridgelux
Vero Series chip-on-board (COB) LEDs with a custom-designed optic
covering each LED. The company will offer six versions of the OLM with
flux output ranging from 2000 lm to more than 4000 lm and a choice of
4000K or 5000K CCTs. Product developers can combine as many as three of
the OLMs in a single fixture design enabling the six base models to
support luminaire designs that can replace 70W to 250W HID lighting.
The OLM is not Bridgelux's first foray into outdoor modules. Back in early 2012, Bridgelux developed a module based on one of its LED arrays in a large discrete package
and supplied the product along with exclusive partner Chevron Energy
Solutions to retrofit projects. Bridgelux said that since the retired
design still serves in a number of projects although the exclusive
relationship with Chevron is over. Moreover, a spokesperson said, "The
knowledge gained from that previous experience was invaluable in the
development of the new Bridgelux OLM Series, which will be available
through broad distribution."
Modules in general can accelerate the SSL development process by
handling the LED integrations, mitigating thermal issues, and in this
case including optics that can form the desired beam patterns. For
outdoor lighting, however, the fact that the OLM is also IP-66 rated
against water and dust ingress takes considerable burden off the
development team that needs to ensure reliable operation in harsh
conditions. Brad Bullington, Bridgelux's CEO, said, "We are now
introducing the industry's most advanced and sophisticated LED
sub-system for outdoor applications."
The OLM is based on a Vero 10 LED that enables system efficacy
ranging from 96-124 lm/W. A COB LED is a compromise in an
outdoor-lighting design. Without question a carefully-crafted luminaire
that uses small LEDs and total internal reflection (TIR) lenses can
deliver more precise beam patterns. That said, we expect more outdoor
lighting products to use COBs because they are much simpler to design
into luminaires and provide performance that is suitable in many
applications. The Bridgelux design uses the combination of a reflector
and diffuser lens to control the beam. For more information about beam
patterns see "SSL luminaires must deliver reliable beam patterns in outdoor applications."
Bridgelux said that the modules will be available beginning in June
for customer shipments. The subsystems range from 14W to 40W in power
consumption. Bridgelux is rating the modules for minimum 50,000-hr
lifetime.
