The Benefits and Disadvantages of LED Lighting
The benefits of LED Lighting are numerous. For one, they can be dimmed. For another, they are a perfect choice for high-intensity discharge lamps, which require a long time to restart after cycling. And they can even be dimmed via pulse-width modulation, which lowers forward current. This effect is similar to that of flickering lights, but LEDs can also be used to produce ghost images.
LEDs are cheap, and have many uses. Low-output LEDs are often used in temporary applications such as glowsticks, throwies, or photonic textile. Some even end up in LED art! But it doesn't end there. While the benefits of LED lighting are obvious, there are also disadvantages to LEDs. For example, some LEDs emit more heat than others. So you need to carefully consider the type of light you need when purchasing a kit.
LEDs also last a long time. LED bulbs are now rated for 50,000 hours of operation, which is more than five times longer than the average compact fluorescent lamp. And if used six hours a day, an LED bulb can last up to 23 years. That's enough time for five presidential elections, home remodeling, and an entire generation! The lifespan of LED bulbs varies based on usage. A fixture that is only on a few hours a day can last for 20 years. A fixture that stays on all night would be quickly exhausted. Typically, a new LED fixture starts to dim when it reaches 70 percent of its initial light output.
As with any electrical system, LEDs require the right connection to operate properly. Unlike traditional lamps, LEDs have no filaments to heat up and do not burn. The LEDs' two terminals (the anode and cathode) are connected to a battery through wire filaments. These wires contain two semiconductor materials that are different in composition and electronic properties. The negative semiconductor material contains electrons, while the positive one has holes.
A key factor in choosing LEDs is current consumption. Current consumption is an important factor for measuring the brightness and efficiency of LEDs. High-power LEDs can draw up to 3000mA of current. LEDs also require a driver. Depending on their current requirements, LEDs can be very expensive and can cause a significant energy savings. The Philips Master LED range has in-built circuitry and will work with most transformers, but you will need a separate LED driver for your lighting system.
Single-color LEDs have a narrow band of wavelengths. Blue LEDs emit light in the visible spectrum. LEDs with shorter wavelengths need higher operating voltages. Blue LEDs have an active region of InGaN quantum wells surrounded by thicker layers of GaN, which is called the cladding layer. The relative In/Ga content in the InGa quantum wells controls the emission of light. There are many different colors of LEDs.
LED bulbs last for two to four times as long as traditional lighting sources. In fact, quality LEDs can last for up to 50,000 hours, which is more than double the lifetime of a typical incandescent bulb. The lifespan of LEDs is usually measured in lumens, which is equivalent to the amount of energy that an incandescent bulb consumes. A standard 60W incandescent bulb produces 800 lumens of light.
