Accelerating Advanced Digital Lighting Through a Controls Ecosystem

Kiran Laxman, Senior Manager, Strategy Development
Legrand

The LED evolution is driving a host of new advanced digital lighting applications from high CRI, tunable white to the emerging area of Human Centric Lighting (HCL). While we are still in the early stages of HCL, we are seeing signs of early adoption as color control and task tuning emerge as specification requirements especially in areas such as healthcare, education, and retail. More research is coming out, and we are already anticipating significant demand for this type of lighting, to enhance user experiences in spaces where people live, learn, work and heal.

The LEDs They Are a-Changin’

Dr Giles Humpston, Applications Manager
Cambridge Nanotherm

LEDs have been around a surprisingly long time. Science project curiosities appeared in the swinging 60′s, and then a decade later the first mass-produced and affordable devices became commercially available. Monochrome LEDs are now manufactured in wavelengths that span the deep UV to far infrared, and the power of white LEDs is beginning to resemble an artificial sun. These accomplishments have been achieved by impressive innovations in LED semiconductor physics and optics. Continue reading

Health Benefits of LED Lighting Contribute to Quality Senior Assisted Living at BioStar Lighting’s Project The Piper

Research has shown that LED lighting has positive effects on health including reducing headaches, nausea, Alzheimer’s disease and related dementias, mood disorders, stress, vision loss and eye disorders. In addition to the energy savings, the health benefits make LEDs the ideal choice for healthcare and senior living facilities. Continue reading

LEDS, Light, Smoke and Sound

Giles Humpston, Applications Manager
Cambridge Nanotherm

LEDs and tungsten filament bulbs have two things in common. First, they convert electricity into light.  While neither technology is particularly good at this task, LEDs do at least manage to achieve around 40 percent electrical-to-optical conversion efficiency compared with about 5 percent for a traditional Edison light. In both cases the energy wasted appears as heat. Filament bulbs shed the heat by radiation and convection, while for LEDs the heat is removed by conduction through to a heat sink. Continue reading

Three Ways to Drive LEDs in an Increasingly Colorful World

Paul Golata, Mouser Electronics

In the era of low-power LEDs – when these electroluminescent chips could deliver little more than the glimmer from a glow worm – red LEDs dominated. We used them as status indicators in electrical and electronic equipment, sometimes employing a string of them to indicate relative levels. As materials science and the design LEDs and their substrates progressed, we found ways to create different color LEDs, to dissipate heat from the chips more effectively and to drive the devices to ever-higher power levels.

Promoting Adhesion of Conformable Coatings to Multi-Component PCBs

Jeff Elliott, Technical Writer

Exposure to water, dust, oil, chemicals, movement and extreme temperature changes can damage circuitry.  This problem is exacerbated for multi-component printed circuit boards (PCBs) found in outdoor devices that must withstand a wide range of weather conditions for decades with little or no degradation in performance. Vulnerable devices include environmental sensors, broadcast equipment, power supplies, billboards/signs, automotive components, solar panels and outdoor lighting. Continue reading

Recipe for IoT – Empowered Computers, Lots of Sensors, Lots of Data and Management of Human Factor Concerns

David Bay, Corporate Engineer
OSRAM SYLVANIA Inc.

Given the relative immature status of RFID and internet technologies in 1999, I commend Mr. Ashton for recognizing the importance of such technologies as well as his identification of use cases enabled by their simultaneous use. Continue reading
