Light-Emitting-Diodes (LEDs) are like small bulbs which are famous not because of ‘Diode' part of their action but because they can emit light. One small diode varies between the sizes of 3mm to 8mm across; with such small size, the light they emit is significant but not enough to perform daily tasks in. Therefore a number of diodes are attached on a reflective panel together and then lit; collectively they emit light which is adequate for everyday chores. LEDs are not filament based bulbs, unlike incandescent light bulbs and florescent tube lights. Owing to their filament-less nature, LEDs can bear more electrical shocks and physical shocks which add to their durability. LEDs are very energy efficient product. They consume much lesser amount of electric power to emit same e amount of light as incandescent bulbs and florescent tubes, therefore LED based light sources are good for your pocket since they knock off a significant amount of cash from the electricity bill.
As mentioned in the previous paragraph, LEDs are placed on reflective modules to emit a powerful light beam. These panels can be made into different shapes and sizes as required by the customer. Due to variable panels there are a few shapes that have become popular because of their convenience and their function such as LED Modules and LED Tubes.
LEDs are also incorporated into many decorative devices and their light alone is also used to create special effects in an area. There are products such as LED Bars and LED Flex that are famous for décor.
LED Flex is a thin tube which contains small LEDs at specific intervals in a line. The tube is translucent therefore LEDs cannot be seen and hence the light emitted from the tube id fairly equal from every angle. When lit, an LED Flex looks just like a Neon Light. Owing to this fact, LED Flex has started to replace Neon lights for many reasons. LED Flex is a very flexible tube therefore it can be bent and turned to make almost any shape without breaking, this is the reason why LED Flex is mainly being used for designing signs. LED Flex is also waterproof; hence it is used to decorate many water bodies such as fountains at parks and swimming pools for a pool party. LED Flex can bear a lot of physical pressure and can with stand a lot of temperature difference as well; therefore they are perfect for outdoor rough and tough environment. This is the reason LED flex are used as signaling device when partially embedded in the ground at areas like airports.
Light-Emitting-Diodes are preferred also because they can provide light for about 50,000 hours so LED devices do not need to be replaced very often unlike incandescent bulbs and florescent lamps. Florescent tube lights contain heavy metal such as mercury vapors and poisonous phosphates which are not good for the environment. LEDs do not contain any such dangerous material and hence it is eco-friendly. Due to their efficiency, LDEs are also preferred by places option for an energy conservation program.
