Let’s start with the basics: what is a driver?

A driver is something that converts AC input into DC output.  Most electronics today including your cell phone and laptop operate on DC by converting the AC input coming from the wall outlet.

Sneak Peek

First and foremost, Happy New Year!  We hope you had a wonderful holiday season.

In late 2017, we came together to reflect on our performance and our place in the lighting industry.  We discussed and debated trends, listened to what our customers need, and focused on how we will continue to meet and exceed their expectations.

We Want You To Know

“The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.” – Albert Einstein

We are evolving. 

Let’s cut to the chase, without light humans are helpless.

Historically, to distinguish the color quality of a light source, consumers and manufacturers utilize the Color Rendering Index (CRI) measurement which compares the light source spectral output to an ideal reference source. Traditionally the higher the CRI of the light source, the more natural and authentic objects appear under its illumination, but this has been found to not be true for objects being captured through commercial video cameras.

Background

Twenty-five years ago, ENERGY STAR® launched as a voluntary program managed by the United States Environmental Protection Agency (EPA) to “promote energy-efficient products to reduce greenhouse gas emissions."  Today, ENERGY STAR boasts 2.5 billion tons of greenhouse gases reduced and $362 billion dollars saved in energy bills to date.

“The past is a candle at great distance: too close to let you quit, too far to comfort you.” This quote from Amy Bloom’s novel “Away” represents the current battle taking place in the ancient city of Rome, Italy. A fight that is based on the transformation of the city’s street lights from high pressure sodium (HPS) lamps to light emitting diode (LED) technology.

The new Bridgelux Vesta™ Series of LED lighting components will be available for ordering this summer.  This new family is based on products for tunable white applications.  “Tunable white” is a pretty trendy topic in the lighting industry these days, and for most, its meaning is becoming clearer.  But, let’s spend a bit of time to define what we here at Bridgelux are talking about when we say “tunable white,” and what we think its important attributes are.

BACKGROUND

In June 2016, the American Medical Association (AMA) adopted guidance on high intensity street lights, specifically focusing on LEDs and blue light technology.
