What is Inrush Current?

As our lighting systems become more efficient, and more complicated, new problems arise from within the circuits themselves.  In the immortal words of James Doohan’s character, Montgomery Scott, “The more they overtake the plumbing, the easier it is to stop up the drain.”  Inrush current is one such problem.  In lighting, the energy-efficient electronic ballast (or in the case of LED lighting, the electronic driver) is boosting efficiency at the cost of compromising older components.  This isn’t a new problem, but the newer ballasts and drivers have made it a bigger problem than it was before, and it’s a problem we’d like to address today.

The Rise of the LED Street Light

4

As LED technology continues to manifest in different facets of our daily lives, one place that they are becoming increasingly more popular are the streets. Traditionally, our streets have been illuminated by high-pressure sodium lamps, which utilize excited sodium particles to produce light. LED street lights have proven to have several benefits over these lamps, including producing more light per watt and sporting longer lifetimes; however, there are some drawbacks to these lights, such as glare. Let’s get a better understanding of LED street lights and how they are quickly becoming the new lights that guide our paths.

The Evolution of Artificial Lighting, Pt. 3

12

In Part 1 we covered the origins of pre-electrical lamps, concluding with the popularization of kerosene lamps in 900 AD. In Part 2 we discussed early 19th century experiments with electrical lighting and the creation of the first practical-use incandescent light bulb. Now in Part 3, we go over 20th century modern lighting and the development of halogen, compact fluorescent, and LED lights. Continue Reading
