Chances are, there is a LED product near you at this moment, and maybe you are using a LED monitor while reading this report. LED-based products are all around as, and LED lighting products increase in their numbers every day, and there will be more and more LED lighting products as time passes by. The reason for the increase in LED lighting products is the many advantages they provide, so let’s take a closer look on what these are.
Why use LEDs?
LED lighting products have numerous advantages when compared to their alternatives, but let’s first explain how LED lighting products work. They are made of light-emitting diodes (LEDs) which are sources of illumination, and the light is emitted by solid state electroluminescence – they produce light with less generation of heat and the energy dissipation is largely reduced too. LED lighting products come in various shapes and sizes, depending on their use, which can be commercial, for lighting of shopping centers, for industrial usage for factories or warehouses, or architectural for decorative and general lighting.
What are the advantages?
The most important advantage of LED lighting products is their long life. They last a few cycles longer than a normal light bulb or fluorescent lamps. They can also emit light of the color you need without color filters, they can be very small (even smaller than 2mm), and their response time is very quick. LED lighting products usually don’t fail abruptly like other lighting sources, but by dimming over time – so if you notice your LED light shinning less bright, you will probably have to replace it soon. Light and fluorescent bulbs are rather sensitive to shock and can easily be destroyed while LED lighting products are more sturdy and resistant to outer shock, so they can’t be destroyed that easily.
How about disadvantages?
Of course, as no product is perfect, so the LED lighting products also have their flaws, the biggest being their price – they are more expensive than other lighting products. One big problem is their functioning on low temperatures; other lighting sources generate more heat, and this heat, while usually being a disadvantage, helps melting the snow and ice from the source, but when LED lighting products are exposed to ice and snow, they don’t generate enough heat to melt them, which results in lesser to no visibility, as they can’t melt the snow that covered them. One more problem with LED lighting products is their dependence on polarity – they will glow only with the correct polarity, while other kind of lighting products don’t depend on the polarity. Also, if they are used to light up cities, the light pollution might be greater than with sodium vapor lamps because LED lights are a white light source. Overall, the LED based lighting has many advantages and can be used for various appliances, from Christmas decoration lights to decorating of your home or garden, to lighting up shopping centers and factories, even whole cities, although they are not the first choice for the latter.
