LED Tube otherwise known as light emitting diodes are a semi conductor source of light. LED tubes are used as a source of light and are used in all sorts of appliances and electronic devices. They can be seen in lamps, televisions, laptop screens, computer screens, automotive lights, traffic signals, large displays for advertising and what not. LED tubes have gained massive popularity over the years from when it was introduced back in 1962. LED tubes are used in all sorts of devices that use light to operate, so no matter how common your appliance or device may be, if it omits lights or uses it, you can be sure that there is an LED tube in it. The most basic and conventional forms of LED omitted low intensity red light. But with the advancement on technology and improvement in the design and functionality aspect of LED tubes they are now available is various colors that have stronger brightness than the conventional version. LED tubes are used in many appliances of diverse nature such as in calculators, head lights, brake lamps, indicators, iPods, mobile phones and even mp3 players. Due to its compact size, durability, narrow wavelength and fast switching, LED tubes are also used in most DVD players and radios.
When it comes to comparing LED tubes with the previous light creating sources used, LED tubes have many advantages. For starters, it consumer less energy and power which is very important in our present times, where resources are scarce, also it is very small in size and can be used even in the smallest of appliances. It has greater durability and reliability and hence has a greater life span so it does not have to be replaced time and again. It has increased robustness and strength and is able to provide appliances with the brightest of lights. The very first commercial use of LED light was in car neon indicators and large displays that were used for advertising. Then LED Flood Lights were installed in laboratory and hospital equipment. At that time LED tubes were very expensive and could only be used in such devices. However, as its availability increased, prices dropped and LED tubes were installed in all of the electronic devices and household appliances. LED tubes are even used in radios, calculators, watches, telephones and everything you see around you. It is amazing how such a great invention can become so common and so readily available. May be that is what is so good about great inventions, they benefit the masses. With work being done of these LED tubes they are now available in many wavelengths and colors. You can get LED tubes in red, blue, orange, yellow, green, purple, violet and ultraviolet. Since these LED tubes are available in primary colors, they can be used to make any color they want which increases its application. Moreover, there are different types of LED Downlights you need to choose from and each has different functions and qualities. The basic types of LED tubes present are miniature, mid range and custom designed LEDs.
