First, the difference between LED fluorescent tubes and fluorescent tubes
1. Ordinary tubes are fluorescent lamps, and the light-emitting principle is different from that of LED tubes. Fluorescent lamps emit light when the ballast is energized to generate high voltage instantly, which excites the discharge between two pins inside the lamp tube, and then excites the phosphor to emit light. This process produces high heat. LED light-emitting is the electron migration inside the semiconductor, which produces light, and the light-emitting process does not generate heat. This is why LEDs are called cold light sources.
2. The LED tube has high luminous efficiency and high brightness. Now the best LED fluorescent tubes on the market have a light efficiency of more than 130, which is about twice that of fluorescent lights. That is to say, 18W LED fluorescent lamps can be used as 36W fluorescent lamps. From the actual lighting effect, 18W LED lamp with 130lm/W can be used as 48W fluorescent lamp.
3. The LED lamp has a long service life. The life of LED can reach more than 50,000 hours (excluding power supply), and the life of fluorescent tube (excluding power supply) is 10,000-20,000 hours.
Second, the advantages of LED fluorescent tubes
1. Environmentally friendly lamps
Traditional fluorescent lamps The tube contains a large amount of mercury vapor, and if the mercury vapor is broken, it will volatilize into the atmosphere, causing pollution. However, LED lamps do not use mercury at all, and LED products do not contain harmful substances such as lead, and the shell can be recycled without damaging the environment. LED tubes are recognized as the green lighting of the 21st century.
2. Less heat generation
Traditional lamps use tungsten filaments to emit light, which will generate a lot of heat, while LED lamps have a luminous efficiency of 140LM/W , The light conversion rate is high, the surface temperature of the product is below 60 ℃, no ultraviolet rays are generated, and the documents and clothes will not fade.
3. No noise
LED lamps do not produce noise, which is a good choice for the occasions where precision electronic instruments are used. Suitable for libraries, offices and other occasions.
4. Eye protection
The traditional fluorescent lamp uses alternating current, so it will produce 100-120 strobes per second. The LED tube works with LED constant current, which directly converts the alternating current into direct current, which effectively reduces the LED light decay, starts quickly, has no flicker, and protects the eyes.
5. No mosquito troubles
The LED tube does not produce ultraviolet light, infrared light and other radiation, does not contain mercury and other harmful substances, and generates less heat. Therefore, there will not be many mosquitoes around the light source like traditional lamps. The interior will become more clean and tidy.
6. Wide voltage range
The traditional fluorescent lamp is lit by the high voltage released by the rectifier, and cannot be lit when the voltage is reduced. And LED lamps can be lit within a certain range of voltage (such as AC 85-265V).
7. Power saving and long lifespan
The power consumption of LED lamps is less than one third of that of traditional fluorescent lamps, and the lifespan is also 10 times that of traditional fluorescent lamps. The brightness is basically the same as that of traditional fluorescent lamps. The normal service life is more than 30,000 hours, and the power saving is as high as 70%. It can be used for a long time without replacement, which reduces labor costs and is more suitable for occasions that are difficult to replace.
8, firm and reliable
The LED light body itself is made of epoxy resin instead of traditional glass, which is more firm and reliable, even if it is hit on the floor The LEDs are also not easily damaged and can be used with confidence.
9. Good versatility
The appearance and size of LED lamps are the same as traditional fluorescent lamps, and can replace traditional lamps.
10. Rich colors
Make full use of the advantages of the rich colors of LEDs to make lamps of various luminous colors.
