The controller keeps on monitoring the application requirement in a continuous control loop. It then commands the inverter to produce the required voltage and frequency to meet the application requirements. To do this, the controller, comprised of a microprocessor, takes the input signal from the sensor and compares this with a reference signal. It then generates the appropriate control signal for the inverter to vary its output power.

In a typical application, the controller will monitor process parameters such as pressure, flow rate, temperature or liquid level. For example, an oxygen sensor in a boiler provides a signal to adjust the speed of the fan and control the amount of oxygen in the boiler system.

Today’s drives, using microprocessors, semiconductor power switches, and SMDs are now smaller, compact, cheaper, more reliable and efficient. A typical drive will also include a filter to suppress harmonics generated when converting the DC to AC voltage.

In the past several years, the technology behind our lights has grown tremendously. Although incandescent bulbs were the standard for a number of years, more energy efficient alternatives like Compact Fluorescents (CFL) and Light Emitting Diodes (LED) have become more readily available, affordable and very popular. Because people have been looking for ways to reduce their electrical bills, and lower their overall impact on the environment, LED lighting has become a particularly popular alternative as it has become easier to find. This has resulted in LED lighting companies to manufacture and distribute more LED lights than in the past.

Should You Switch?

The reasons to switch to LEDs are numerous for both homeowners and small businesses. One of the biggest draws to LED lights is its lifespan. Most LED lights will burn for somewhere around 100,000 hours. This translates into roughly 11 years. Whenever you are dealing with this type of lifespan, you will probably end up calling an electrician in Los Angeles to come change out the light fixture before you ever have to change the bulb. LEDs not only last longer, but they also use much less electricity than both incandescent and CFL bulbs. They also produce less heat, resulting in a long-lasting, low-energy, low temperature operation.

Are They Expensive?

One of the few negatives that LED bulbs have is that they have a higher up-front cost than many other options. Although they boast the longer life span, reduced energy consumption and low heat, LED lighting is still more expensive than CFL and Incandescent bulbs. For this reason, many people choose other types of bulbs over them.  Those that go with the LEDs typically find out that they will pay for themselves through reduced energy usage. As always, don’t hesitate to contact The Electric Connection with any questions about LEDs, light fixtures or any other electrical topics. We’re always glad to help.

Luxurious lighting styles are in the eye of the beholder. It can be an over-the-top glamorous chandelier with ornate details to a simple and clean glass globe lighting pendant with a singular, classic antique bulb. Whatever luxury lighting means to you, it can be attained without breaking the bank if you carefully shop and compare.

Traditional Luxury

The foyer might be a best place to start your luxury lighting quest, as it’s where you greet your guests. Consider large-in-scale pendants, which make a statement in what could otherwise be a plain space.

The Socorro lighting collection by Sea Gull Lighting is influenced by a classic, barbed Quatrefoil shape. Its rustic look is created by both Cerused Oak and Stardust finishes. Pictured here is the six-light foyer pendant.

Modern Luxury

As many homeowners use their kitchen as a central gathering place, here, too, presents an opportunity to showcase your idea of luxury lighting. Imagine family and friends clustered around a kitchen island, where a carefully placed pendant—or two or three—could become a conversation piece. Here, these stunning, modern Lexi three-light pendants from Feiss draw the eye upward to its textured crystals floating within a laser cut frame. A White Shantung silk shade sits within the crystal drum while a glass diffuser softens the light.

Contemporary Luxury

You might think an opulent chandelier or a cluster of colorful pendants are expensive, but there are many affordable versions that will still add a “wow” factor.  If your dining room is used for special occasions, you might consider something bold. The Carondelet four-light chandelier from Sea Gull Lighting features a cascade of faceted, linear glass crystals delivering the ultimate sparkle. Hanging them in a pair is an affordable way to make a luxurious and indelible impact.

Glamorous Luxury

With the eggplant color paint, plush silver rug and other modern furnishings, this living room is the perfect backdrop for the Marquise Collection by Feiss. Designed to follow the cut of a marquise diamond, the lighting collection has a delicate, exposed metal frame adorned with a silver leaf application—then it’s finished with a string of hand-applied beading to capture the light. Shown here are the Marquise three-light pendant and one-light wall sconce.

Hollywood Regency Luxury

The Hollywood Regency style is very popular, as it harkens back to era when heroes such as Greta Garbo and Douglas Fairbanks graced the Silver Screen, and the nation’s total wealth more than doubled. Note how the Burdeen sconces by Feiss flanking the window and soaking tub enhance this spa-like look with their glass etched backplates and three candelabra lights. There’s also a one-light Burdeen sconce that’s even more affordable.

Mountain Luxe

Mountain Luxe design could be easily defined as mountain lodge meets high rise penthouse—creating a perfect place to nestle by the fireplace while sipping a hot toddy. The unusual coupling of dark and light fashioned into a lovely round silhouette in this six-light Colorado Springs semi-flush ceiling fixture by Feiss embodies Mountain Luxe with its clear glass crystals floating in metal rings, which are then threaded onto a chain and strung into its drum shade.

PRO TIP: Be it traditional to transitional or contemporary to modern, to achieve the luxury look you want in your home seek out affordably-priced, high quality looks that emulate more expensive designs. Think “Get the Look” feature stories that run in magazines such as Glamour where high priced clothing is compared to low priced clothing with the same aesthetic. It works!
