LED light bulbs have a longer life than traditional incandescent light bulbs and require less energy. They come in a variety of shapes, offer a variety of sheens, and come in different base widths to match almost any light fixture. On today’s market, many manufactures can provide a wide selection of LED light bulbs to help create the lighting effect your desire, for example: LED projection light, LED bay light, and LED street light etc.
Every light fixture benefits from a well-chosen light bulb. And the bulb offer both practical and aesthetic advantages over other lights. On today’s market, you always have many options. Why LEDs are so popular in these days? This is because they have so many advantages. In addition to energy efficient, LEDs are durable and shockproof unlike glass bulb lamp types. More importantly, they are eco-friendly.
In above, we have talk about the advantages of LED. What is LED? An LED (light-emitting diode) is a two-lead semiconductor light source. It is often small in area and integrated optical components may be used to shape its radiation pattern. The LED consists of a chip of semiconducting material doped with impurities to create a p-n junction. As in other diodes, current flows easily from the p-side, or anode, to the n-side, or cathode, but not in the reverse direction.
The first commercially usable LEDs were developed in the 1960’s by combining three primary elements: gallium, arsenic and phosphorus to obtain a 655nm red light source. As LED technology progressed through the 1970’s, additional colors and wavelengths became available. In a word, LEDs have gone from infancy to adolescence and are experiencing some of the most rapid market growth of their lifetime. Today, there is a myriad of applications for LED, for example: indication lights on devices, small and large lamps, traffic lights, large video screens, sings, and street lighting.
