Nowadays, LED lights are widely used, and more and more people are using LED lights. But why so many people are using LED lights? Do you know? And why LED lights are more widely used than ordinary lights? Let’s talk about the following.
We generally talk about ordinary light bulbs, referring to incandescent light bulbs. It is the type that has been in existence since Thomas Edison patented his invention in 1879. the basic structure of an LED lamp is a piece of electroluminescent semiconductor material placed on a shelf with leads, and then sealed around with epoxy resin to protect the internal core.
So what is the difference between LED lights and ordinary lights?
First, their light-emitting principle is different. LED light-emitting is the migration of electrons within the semiconductor, A light source is produced, and the process of emitting light does not generate heat. It is the reason why LED is called a cold light source. Ordinary lamps are fluorescent lamps, the light-emitting principle and LED lamps are not the same. Fluorescent lamp light is the ballast energized by an instantaneous generation of high voltage, excites the internal discharge between the two pins of the lamp, and then excites the phosphor light. This process generates high heat. This process produces high heat ordinary lights rely on current flow through the filament to make it heat up into high-temperature discharge light.
Second, environmentally friendly lamps. Traditional fluorescent lamps contain a large amount of mercury vapour. If broken mercury vapour. It will volatilize into the atmosphere, producing harmful substances. LED fluorescent lamps are recognized as the green lighting of the 21st century.
Third, efficient conversion reduces heat. Traditional lamps and lanterns will produce a lot of heat, while LED lamps and lanterns are all converted into light energy and will not form a waste of energy. And the document, clothing will not produce the fading phenomenon.
Fourth, no noise. LED lamps and lanterns do not produce noise on the use of fine electronic instruments for the best choice. Suitable for libraries, offices, and other places.
Fifth, mild lamp to maintain the eyes. Traditional fluorescent lamps use alternating current, so every second will produce 100-120 times the strobe. LED lamps and lanterns are the direct conversion of alternating current to direct current, will not work a flicker phenomenon, to maintain the eyes.
Sixth, no ultraviolet light, and no mosquitoes. LED lamps and lanterns do not produce ultraviolet light, so there will not be like traditional lamps and lanterns. There are many mosquitoes around the light source. The Indoor will become clean and hygienic.
Seventh, the voltage can be adjusted to 80V-245V. Usual fluorescent lamps are released through the rectifier at high voltage to light up when the voltage is lowered and can not be lit. LEDs, on the other hand, light up within a range of voltages and adjust the brightness.
Eighth, save energy and longer life. LED fluorescent lamp power consumption is less than one-third of the traditional fluorescent lamp life and is also ten times the classical fluorescent lamp. And can be used for a long time without changing, reducing labour costs. The same light effect of LED and usual light source used in a 2000-meter bridge, LED guardrail lamp electricity consumption of about 10 degrees per hour, conventional light source about 80 degrees, can save eight times the cost. More suitable for hard change the place.
Ninth, consolidate reliable, lasting use. LED lights detailed themselves using epoxy resin rather than the traditional glass, more consolidated and reliable, even if smashed on the floor LED will not just damage, can rest assured that the use.
This comparison down, LED lights than ordinary lights long life, stable performance. The environmental requirements are not high ten years to replace the LED lights once it saves electricity and avoids the pain of frequent light changes. An LED light source is the use of DC drive ultra-low-power devices, shock-resistant, shock-resistant, no thermal radiation, safe, stable, reliable, no need to consider heat dissipation; light body dexterity, easy installation; novel style, excellent craftsmanship. Both labour-saving and labour-saving. However, although the LED light source has low energy consumption and long life, its relatively high cost and the power supply requirements are relatively high (requiring constant current and brightness by the current control). But the now is too high it is easy to burn LED, so use with care.
