Ask an Engineer for Griswold-Style Display

On December 15, 2020 in All, IoT, Lighting, Maker by Charles Byers

With a bit of clever design and construction, it is possible to create a very striking snowflake pattern generator as part of a holiday light display. Here are four implementation ideas for a homemade device that will surely be the coolest front yard ornament on your block.

Keeping the Lights On: ESD and Thermal Protection for LED Lighting Systems

On January 29, 2019 in All, Circuit Protection, Lighting by TDK

There are several factors that can affect solid-state lighting including stress, packaging-related, and component-related issues. Discover the key threats that affect the reliability of LED lighting systems.

LEDs and Wireless Tech Combine to Build Intelligent Lighting

On January 3, 2018 in All, IoT, Lighting by Steven Keeping

Both LED lighting and low-power wireless technology have been decades in gestation. Although originally developed for different applications, the two technologies have converged to revolutionize lighting applications that provide more than just illumination.

Here Comes the Sun

On November 7, 2016 in All, Lighting by Mark Patrick

A team of engineers in Germany is addressing the challenge of getting enough light with a new, app-controlled intelligent lamp. The HEAVN One is a desk lamp, a daylight lamp and a room illuminator, all in one. It takes the well-established idea of the health benefits of light, and expands it in three different ways.

Feeling Blue? Human Health in Light of LED Streetlights

On July 12, 2016 in Lighting by Paul Golata

White LEDs used in street lighting may consist of packaged combinations of Red, Green, and Blue LEDs, but more often than not employ blue LEDs, which are built generally from indium gallium nitride (InGaN) and have a yttrium-aluminum-garnet (YAG) (Y3Al5O12) phosphor coating placed on their emitter or emitter’s optic. From the base color of blue light, white light can be realized and utilized for white LED streetlights. But does this blue light found in LED streetlights make humans experience any negative impacts?

LED Headlights…Coming Soon the Masses!

On February 18, 2016 in Lighting by Barry Manz

As High Intensity Discharge (HID, xenon) and LED technologies are the only truly modern vehicle light sources, unless you own a luxury vehicle chances are you (like me) are missing out actually being able to see well into the night. The difference between what these two technologies and 50-year-old quartz-halogen bulbs deliver is like night and day. Fortunately, thanks to the dramatic advances and reduced cost of high-brightness LEDs, high-performance forward lighting is now about to be available to the rest of us.

Misty Beginnings for LED Lighting

On February 10, 2016 in Lighting by Steven Keeping

There is little debate that LED lighting has hit the mainstream with the technology projected to achieve a market share of 84% in the general illumination market by 2030 (saving the equivalent of the total energy consumed by nearly 24 million U.S. homes compared to today’s inefficient lighting, according to the U.S. Department of Energy). But like many emerging technologies, LED lighting has taken a long time to actually emerge – much longer than you might think.

Journal of a Newbie Maker

On August 28, 2015 in All by Colin Carter

I’ll cut right to the chase here: I’m not an engineer. By education, I’m a technical writer. By pastime, I’m a musician, homebrewer, reader, cyclist, record collector, house cleaner, and animal lover. In the past couple of years, I’ve added the mantle of maker. Or tinkerer. Or DIYer. Whatever you want to call it, I built a circuit from a handful of components — and it works! You may remember your first successful build and your sense of accomplishment. Here’s my story.

King of the Road

On July 9, 2014 in Lighting by Paul Golata

Recently a major LED lighting supplier, OSRAM, announced that the 2015 Ford F-150 will be the first truck to feature a full LED forward lighting system. A key performance and styling differentiator, the innovative LED lighting system is comprised of a low beam, high beam, light driver module, turn module, and park module.

Bike Night Light Brite

On May 12, 2014 in Lighting by Paul Golata

Do you recall growing up as a kid and playing with Lite-Brights? I can remember it almost like it was yesterday. It came with that ubiquitous patterned picture to make a clown face and a sail boat. The fun came from completing the build out the pattern and then flipping the off the light switch and seeing everything glow, lighting up the darkness.
