In the past few weeks, we’ve concentrated on the significant benefits that an LED retrofit can deliver to commercial facilities and the details of how our energy audit and retrofit product management work. In this week’s article, we will return to the reasons that LED light bulbs can deliver great savings.
We’ll start with a review of what LED light bulbs are. The first steps of the discovery of the light-emitting diodes (LED) are, according to History of Lighting, were in 1907 by a British scientist at Marconi Labs. Several significant leaps forward, and we have the modern LED bulbs that the first commercially viable LED bulbs were manufactured in 1994.
How it Works
How it Works
The diodes are a type of semiconductor, just like in your phone or your computer. When electricity passes through these semiconductors, they emit light. With small changes, the light can be green, blue, amber, orange, or red. You’ll notice that white is not on that list of colors. To get white, one of the colors has to be converted to blue, and then phosphor is added, and the light turns white. An LED light bulb is actually a collection of small diodes. This quality makes it easy to make very small wattage light bulbs and larger light bulbs, the number of diodes just needs to be adjusted.
Their electric source needs are different from a regular light bulb that operates on 120 or 277 volts. Instead, they need a direct current that delivers a low voltage, and this requires the presence of what is called a driver. Additionally, there is another part of the bulb that is called the optics. This controls how the light exits the bulb. The type of optic determines of the light is a narrow beam or provides a wide, general light.
Advantages of LED
- LED bulbs are four to five times as efficient as incandescent bulbs and also more efficient than fluorescent or HID lighting.
- LED light bulbs last 10–20 times longer than incandescent bulbs.
- These bulbs are also more reliable in extreme temperatures. LED light bulbs will turn on with full light in extreme colds, which, for example, incandescent bulbs lights can’t do.
- LED lights are also dimmable, which adds an element of flexibility that other bulbs do not have.
- The bulbs of an LED light bulb is not made of glass, so it is impact-resistant, adding more longevity to already impressively long-lived bulbs.
- If you are concerned about the environment, LED bulbs are for you! They do not release UV or infrared radiation and contain no mercury as compact fluorescent bulbs do.
- Using LED lights to reduce electricity bills, carbon footprints, and maintenance costs since they do not have to be replaced as frequently.
- LED lights are great for many uses, from exterior landscaping lighting to office buildings, and sports arenas.
- The level of control that people have over the light that LED technology is perhaps the most noteworthy advantage. LED light can be cool or warm, is dimmable, comes in several colors, and the beams can be either compact or diffuse.
