PACKAGED LEDS
Kyocera debuts violet-based white
and color packaged LEDs, lights
Japanese façade
Kyocera has announced a major
building-façade lighting project in Kyoto, Japan, and at the
same time revealed the first
major commercial use of its vio-let-emitter-based LED technology that had previously only
been discussed in research and
development (R&D) terms. The
Wacoal Holdings building façade can be bathed in white or dynamic
RGB light — hues that Kyocera said are suggestive of Kyoto. The
packaged LEDs, meanwhile, use a violet emitter with RGB phosphor mixes, with the exact mix determining whether white or
color light is realized.
In terms of producing a high-power white LED, the Kyocera technology appears to parallel the violet pump and phos-
AUTOMOTIVE LIGHTING
Osram announces LED
and laser products for
automotive applications
Osram Opto Semiconductors used the fall Electronica
trade fair as a venue to launch some new automo-tive-targeted LED and laser-based components. The
surface-mount device (SMD), four-channel laser
demonstrated at the show is a prototype product
intended for LIDAR (light detection and ranging)
applications and such systems will be critical in
the evolution of autonomous or self-driving autos.
Meanwhile, the company continues to evolve its
LED headlamp product portfolio, announcing the
commercial availability of the three-to five-emitter
Oslon Black Flat S SMD LEDs with each LED in the
package being individually controllable.
LIDAR technology is being used in many different applications, as we described in a feature article focused on LED-based LIDAR systems
MONUMENT LIGHTING
Landmark Niagara Falls
get dynamic RGBW
LED lighting upgrade
The Niagara Falls Illumination Board has unveiled a new
LED-based dynamic lighting system using red, green, blue,
and white (RGBW) luminaires or projectors that makes the
famed falls even more spectacular at night. The twin cities of Niagara Falls, Ontario, Canada and Niagara Falls, N Y
collaborated on the $4 million solid-state lighting (SSL)
project that was undertaken by a consortium of lighting
specialist and contracting firms including Ecco Electric
Ltd, Salex Inc, Mulvey & Banani Lighting Inc, Sceneworks,
and Stanley Electric.
The Niagara Falls were previously lit by xenon sources
with the light projected from the Illumination Tower located
in Queen Victoria Park on the Canadian side of the river.
There were also a few fixtures in a bunker in the river gorge
used to illuminate one side of the American Falls. That system had been in place for some 20 years.
The Illumination Board issued an RFP back in 2014 globally, seeking suppliers that could replace the 21 fixtures in
the existing system on a one-for-one basis and increase the
white-light level on the falls from 5 fc to 2–3 times that level.
At least 30 companies/teams responded initially and seven
moved to a finalist stage before the winners were selected.
Salex president Nick Puopolo led the process of retrofitting the system with LED lighting, bringing a proposal to
the Niagara Falls Illumination Board along with Ecco Electric and ultimately participating in bringing the idea to fruition. Salex is a lighting and controls sales agency and Ecco
is an electrical contractor.
