Are LED tubes not as good as ordinary fluorescent lamps?

Summary: The parameters of led day lamps are far superior to ordinary fluorescent lamps. The question is how you choose. Don't be greedy for cheap. Choose the products of regular manufacturers, you can use them at ease. At present, many users don't know much about the actual use effect of LED tubes, so they should check relevant information. Don't be misled by wrong public opinion. It is undeniable that because some bad manufacturers produce low-quality LED tubes, the parameters are not ideal, they do not meet the requirements, and the lifespan is still very short. This greatly destroys the brilliant image of LED tubes and affects consumers' desire to buy. This is not normal. The market should step up efforts to crack down on counterfeit and shoddy products, let qualified products become popular, and return genuine LED tubes to fairness.

Are LED tubes really inferior to ordinary fluorescent lamps? Let’s take a look at the principle of luminescence and it’s clear at a glance

First, the working principle of fluorescent lamps

A large number of electrons emitted when the filament is heated move from the low-potential end to the high-potential end at a great speed under the action of the high voltage at both ends of the lamp tube. In the process of acceleration, it collides with argon molecules in the tube, causing them to rapidly ionize. Argon ionization generates heat, and the heat causes mercury to generate vapor, and then the mercury vapor is also ionized and emits strong ultraviolet rays. Under the excitation of ultraviolet rays, the phosphor in the tube wall emits almost white visible light. When the fluorescent lamp is normally lighted, only a low current is allowed to pass through the two ends of the lamp, so the voltage applied to the lamp is slightly lower than the power supply voltage, but the fluorescent lamp needs a higher voltage breakdown when it starts to work, so a town is added to the circuit. The current device can not only generate a higher voltage when starting, but also stabilize the current when the fluorescent lamp is working.

Second, the working principle of led tubes

The principle is to use LED semiconductor chips to emit light, and the structure is more complicated than that of fluorescent lamps. There is a housing + LED lamp board + LED driving power supply, and auxiliary circuits such as ballasts are no longer needed.

The working process is that the high voltage 220v is rectified and filtered by the LED constant current source. It becomes a DC voltage to work, and the current is constant. The lamp beads on the LED lamp panel are supplied to work at the rated current. The LED lamp panel has a string And requirements. So this kind of light is stable, there will be no AC flicker, the power conversion rate is as high as 90%, and it has the characteristics of low heat generation, high light efficiency, long life, environmental protection, and energy saving. Its advantages are far higher than fluorescent lamps.

It can be seen that fluorescent lamps and LED tubes have different light-emitting principles, resulting in different lifespans and different prices. The comparison of many factors can see that its benefits are obvious.
