The Difference Between Fluorescent Lamp And LED Lamp

Ever since Edison invented the light bulb, human life has been bright. Now if people leave the light of electric lamp, completely is inconvenient to access at night. The development of the light bulb also started from the simple tungsten filament bulb to the various types of light bulb now. Led lamp is one of the most commonly used light bulbs now, so what is the difference between LED lamp and fluorescent lamp, these are things we need to know, follow me to understand what is the difference between LED lamp and fluorescent lamp.

LED Lamp

Fluorescent Lamp

What differentiates do Led lamp and fluorescent have? Above all, ordinary lamp is fluorescent lamp, its luminous principle is different from LED lamp. Fluorescent lamp luminescence is through the ballast is energized instantaneous high voltage, excitation lamp tube between the two pins discharge, and then excitation phosphor luminescence. This process produces high heat. However, LED luminescence is generated by electron migration inside the semiconductor, and the luminescence process does not produce heat. This is why LEDs are called cold light sources.

Secondly, LED lamp lighting efficiency, high brightness. Now on the market, good LED daylight tube light efficiency can reach more than 130LM, is about twice the light efficiency of fluorescent lamp. In other words, an 18W LED fluorescent lamp can be used as a 36W fluorescent lamp. From the actual lighting effect, 130LM /W 18W LED lamp can be used as 48W fluorescent lamp.

Thirdly, the service life of LED lamp is long. The life of LED can reach more than 50000 hours (without power supply), and the life of fluorescent lamp(without power supply) is just 10000-20000 hours.
