What are the advantages and disadvantages of LED tubes？
First, the advantages of LED tubes:
1. Environmentally friendly lamps: traditional fluorescent tubes contain a large amount of mercury vapor. If the mercury vapor is broken, it will volatilize into the atmosphere, causing pollution, but LED tubes do not use mercury at all, and LED products do not contain harmful lead such as lead. Substances and shells can also be recycled without damaging the environment. LED tubes are recognized as green lighting in the 21st century.
2. Less heat generation: traditional lamps use tungsten filaments to emit light, which will generate a lot of heat energy, while LED tubes have a luminous efficiency of 140LM/W, high light conversion rate, product surface temperature below 60 °C, and no ultraviolet rays are generated. , the clothes will not fade.
3. No noise: LED tubes do not produce noise, which is the best choice for occasions using precision electronic instruments, suitable for libraries, offices and other occasions.
4. Eye protection: The traditional fluorescent lamp uses alternating current, so it will generate 100-120 stroboscopic times per second. The LED tube uses LED constant current to work, which directly converts alternating current into direct current, effectively reducing LED light decay. Quick start, no flicker, eye protection.
5. No mosquito troubles: LED tubes do not produce ultraviolet light, infrared light and other radiation, do not contain mercury and other harmful substances, and generate less heat, so there will not be many mosquitoes around the light source like traditional lamps, and indoors will Become more clean and tidy.
6. Wide voltage range: traditional fluorescent lamps are lit by the high voltage released by the rectifier, and cannot be lit when the voltage decreases, while LED tubes can be lit within a certain range of voltage.
7. Power saving and long life: The power consumption of LED tubes is less than one third of that of traditional fluorescent lamps, and the lifespan is also 10 times that of traditional fluorescent lamps, which is basically the same as the brightness of traditional fluorescent lamps. Up to more than 70%, it can be used for a long time without replacement, reducing labor costs, and is more suitable for occasions that are difficult to replace.
8. Sturdy and reliable: The LED tube body itself is made of epoxy resin instead of traditional glass, which is more sturdy and reliable. Even if it is hit on the floor, the LED will not be easily damaged and can be used with confidence.
9. Good versatility: LED tubes have the same appearance and size as traditional fluorescent lamps, and can replace traditional lamps.
10. Rich colors: Make full use of the advantages of rich LED colors to make lamps of various luminous colors.
Second, the shortcomings of LED tubes:
1. The problem of heat dissipation is always the biggest problem of LED products, and the impact of overheating on LEDs is fatal. However, with the development and maturity of LED technology, after the LED light efficiency is improved, the heat dissipation problem will be gradually solved.
2. The price is high. Now the LED manufacturing cost is high and the application is relatively small. It is mainly used in urban lighting projects and decoration projects in China. However, the prices of LED products in the upper, middle and lower reaches are also reduced rapidly, and they will be widely used in the future. , will also reduce the cost due to the scale effect.
3. The problem of power supply. Now LED tubes can only use low-voltage direct current, so it is necessary to have a power supply that converts alternating current into direct current, but the power supply is the short board of LED tubes, because the normal service life of the power supply is about 2000 hours, and the price It is more expensive, but now some people have started to use LED chips directly with alternating current, and they have also achieved certain results. Although their products have not been officially announced as successful in research and development, I believe that in the near future, humans will soon be able to use direct alternating current. LED products.
