Difference between fluorescent lamp and LED lamp
2023-02-08
1. Luminous principle
Ordinary lamp is a fluorescent lamp, light-emitting principle and LED tube is not the same. Fluorescent lamp light is the ballast power instant to generate high voltage, stimulate the discharge between the two pins inside the lamp, and then stimulate the phosphor light, this process produces high heat. LED luminescence is the electron migration inside the semiconductor, resulting in luminescence, and the luminescence process does not generate heat.
(2) Heat generated
The traditional fluorescent tube will produce a lot of heat energy, and the LED fluorescent lamp is all converted into light energy, will not cause the waste of energy.
3. Service life
The life of the LED can reach more than 50000 hours (without power supply), and the service life of the fluorescent tube (without power supply) is 10000 to 20000 hours.
4. Light efficiency
LED tube has high luminous efficiency and high brightness. Now on the market good LED fluorescent tube light efficiency can reach more than 130, is about twice the fluorescent light efficiency. In other words, the 18W LED fluorescent lamp can be used as a 36W fluorescent lamp. From the actual lighting effect, the 130lm/W 18W LED lamp can be used as a 48W fluorescent lamp.
