These days, more and more homeowners are making the switch to LED lighting for their homes. Not only does LED technology offer a nice, white light, it is exceptionally energy-efficient, so homeowners can save a lot of money over the years. LED lighting doesn’t need to be replaced frequently like incandescent lightbulbs, and you can expect most LED bulbs to last at least 15 to 20 years, or even longer. Let’s take a look at LED’s, what they are, and the various types of LED lights available.
What is an LED?
LED stands for light-emitting diode, and it is a type of electronic source of light. This type of lighting is a lot different from traditional incandescent and halogen lighting, in several ways. To begin with, they are going to last a lot longer than traditional lightbulbs, they consume a lot less energy, and they don’t emit very much heat. In fact, they are actually cool to the touch.
LED bulbs are a lot more durable than the incandescent light bulbs you are used to. If you drop one, it is not going to shatter into a million tiny pieces. These lights do not have any glass tubes or filaments, which also makes them safer than traditional bulbs, because they contain no lead or mercury. They are made to fit most light fittings, including B22, E27, GU10, and MR16.
How much Power do LED Bulbs Use?
One of the best things about LED bulbs is that they use about 90 percent less energy than incandescent and halogen bulbs that are of equal brightness. LED lights are much more efficient when it comes to converting electricity (measured in watts) into light (measured in lumens). So, an LED bulb that is 4 watts is comparable to a 50-watt halogen bulb.
How Long do LED Bulbs Last?
Depending on the bulb, an LED bulb can last as long as 50,000 hours. This is because of the thermal management. Heat is removed via heat sinks, which helps to increase the lifespan of the bulb as it slows down the depreciation of lumens. The technology is constantly evolving, so soon it won’t be uncommon to see bulbs that can last for 100,000 hours or longer.
Types of LED Lights
When it comes to types of LED lights, you have several options to choose from. Most lights can easily be replaced with LED bulbs, without the need for any special adapters, so you can use your existing fittings with no problems. LED lights are available in standard GLS, candle bulbs, golf ball bulbs, reflector bulbs, spotlights, and tube lighting.
- Miniature LED Lights – The first LED lights we are going to discuss are miniature LED Lights. You will find these in most of the smaller devices that you use every day, including televisions and mobile phones. These are made with pre-defined sizes and shapes that are standard so they are compatible with a variety of circuit boards.
- High Powered LED Lights – You can thank the latest in semiconductor technology for this type of LED lighting. These lights have a very high output, and can produce a lot of high intensity light. These lights come in a variety of sizes and shapes. They are often used in LED strips that are used to light rooms and walls. These are lights that are mounted onto a circuit board that is highly flexible. Often, they come with adhesive stickers on the rear side of the strip so they can be stuck right on to a variety of surfaces, and the lights are often used for decorative purposes. One thing to note about high powered LED light is that it has a much higher heat dissipation than other types of LED lighting, and they must be mounted with a cooling system that has a heat sink.
- Application Specific LED (AS-LED) – This type of LED light is generally made for a specific use or application, such as public displays, multi-colored LED lights, and digital billboards. If it is to be a bi-colored light, two separate diodes are mounted on one frame. There are two pins, with one being common, and this can be anode or cathode. In the case of tri-colored LED lights, there are two diodes on one frame, with three pins. There is also the RGB LED (red, green, and blue) which has a number of uses.
- SMD LED (Surface Mounted Device) – This is considered to be the next generation of LED lighting, and many bulbs now have SMD chips. Why? Because these chips make the LED lights a lot brighter than older styles of LED lights. With this type of LED lighting, the LED is soldered right onto the PCB, so it doesn’t take up nearly as much space, and there is a much better thermal connection.
- COB LED (Chip on Board) – This is the latest in LED technology, and it involves using chips that usually have nine or more diodes. These lights have no casing, so the LED light is much denser than SMD LED light. You will enjoy a consistent beam of light that is very controlled, and there are no visible light points for better optics. This technology gives a much better ratio of lumens per watts, and it offers the best optimal cooling, which means that these lights are going to last even longer than regular LED lights.
Whether you are looking to light up your home or office, or even want holiday or party lights that are going to last for several decades, LED technology is definitely something that you need to learn more about. LED bulbs tend to work better than traditional bulbs, and they are going to last for several years. In the case of holiday lighting, it can last for several decades, so you likely will never have to go out and buy another set. If you want to save money on your energy bills and have lighting that is better in quality and safer than incandescent bulbs, check out all of the benefits that LED bulbs have to offer.
