When I was a kid growing up in Los Angeles, I never saw a ceiling fan in my friends’ homes. We called them “swamp coolers,” and they appeared as props in movies that were set in the deep South or in Casablanca.

While I never saw a real one as a kid, ceiling fans date back to the late 1800’s, when they were originally powered by water. In 1882, Philip Diehl, the German-American inventor of the motor for Singer sewing machines, adapted his sewing machine motor for the ceiling fan. Electric ceiling fans grew in popularity and were quite commonplace in both America and abroad by the 1920’s. Movies from the 20’s often feature them in restaurants and hotel lobbies.

Between the 1930’s and 1950’s in the U.S., however, the fans went out of vogue. Thus, my lack of experience with them as a child (which dates me as a Baby Boomer!) However, with the oil shortages of the 1970s, we started to wake up to the cost of electricity, and the fans experienced a revival. Since the 1970’s their popularity has gone up and down, but has been in uptrend since about 2000, when energy conservation again became a priority.

Most new buildings are now using a variety of electrical and electronic equipment. As such, the contractors have to design a wiring schematic that will deliver power to a wide and diverse range of devices that include traditional and modern electrical loads.  The wiring must also provide a means of supplying power to the monitoring and control devices such as wireless sensors, thermostats, automatic light controls, thermostats, the IoT, and other web-based technologies.

The electrical requirements will vary from one building to another and may include a combination of the following components:

The type and use of a building structure influences the type of wiring to use. And the building owner and electrical contractor should consider current and future power requirements when determining the size of conductors, raceways, protective gear and other necessities.

Electrical motors are wonderful devices that are used in a myriad of ways, making things easier in our daily lives as well as a wide range of industrial applications. When these gadgets fail, work often grinds to a halt till they’re back up and running, and the reasons for electrical motor failure can range from the commonplace to the bizarre.

While the list of possible causes can go on forever, we’ll take a look at some of the most common ones here:

Exposure to high heat is a top culprit for all kinds of equipment failure, and ranks as the number one reason for motor malfunctions and deterioration. Optimal running temperatures extend motor life, which is why they should be your first priority.

In fact, most of the other possible reasons for electrical motor malfunctions also lead to the generation of extra heat. A rise of even a few degrees can cause trouble over time, and if motor windings are exposed to an extra 10° C of heat, the life of their insulation drops by half!

The term “light box” can mean a few different things, but from a lighting perspective it typically refers to a backlit display panel. Light boxes are most commonly used for advertisements or other commercial displays. You’ve probably seen them in trade show booths, restaurants, airports, nightclubs, offices, hotels, museum exhibits, and retail shops. That’s right, light boxes are everywhere.

One of the most common uses for light boxes is the commercial advertisement. You see these in large spaces like terminals or outdoors at bus stops. They capture the attention of passers-by and create lasting impressions. The light box pictured below is one of the biggest I’ve ever seen.

One of the most obvious places you’ll see light boxes are along the walls inside and outside of movie theaters. Sometimes lines of light boxes stretch incredible distances, advertising all the movies being shown in large theaters.

In fact, light boxes can be a fun addition to any home and can be used for as many purposes as you can imagine. Sure, you could illuminate a movie poster of your daughter’s favorite movie. But you could also make a custom sign saying whatever you want. I really like the light box below, created at home for home.
