What are the advantages and disadvantages of fluorescent lamps?
Fluorescent lamp is also called fluorescent lamp. It is a low-pressure arc discharge light source. It uses low-pressure mercury vapor to release ultraviolet rays after being energized, so that the fluorescent powder emits visible light. We don’t need to understand them very well. They are relatively common nowadays. One of the lamps, but there are still many people who don’t know much about it. So what are the advantages and disadvantages of fluorescent lamps? Now, benwei will explain it for everyone, let's take a look.
What are the advantages and disadvantages of fluorescent lamps?
Compared with incandescent lamps, fluorescent lamps are more energy-efficient, have a longer life span, a more variable appearance, more colorful colors, and better applicability. However, the price of incandescent lamps will be more expensive than fluorescent lamps, and the actual light efficiency of incandescent lamps is far from theoretical.
1. LED fluorescent lamp, energy saving and environmental protection
The traditional fluorescent lamp contains a large amount of mercury vapor, if it is broken, the mercury vapor will volatilize into the atmosphere. However, LED fluorescent lamps do not use mercury at all, and LED products do not contain lead, which protects the environment. LED fluorescent lamps are recognized as green lighting in the 21st century.
2. Efficient conversion, reduce heat generation
Traditional lamps generate a lot of heat energy, while LED lamps convert all electrical energy into light energy without causing energy waste. Moreover, the documents and clothes will not fade.
3. Quiet and comfortable, no noise
LED lamps do not produce noise and are the best choice for occasions where precision electronic instruments are used. Suitable for occasions such as libraries and offices.
4. Soft light, protect eyes
The traditional fluorescent lamp uses alternating current, so it will produce 100-120 strobes per second. LED lamps directly convert alternating current to direct current without flickering and protect the eyes.
5. No ultraviolet rays, no mosquitoes
LED lamps do not produce ultraviolet rays, so they do not have a lot of mosquitoes around the lamp source like traditional lamps. The interior will become cleaner, sanitary and tidy.
6. The voltage is adjustable from 80V to 245V
The traditional fluorescent lamp is lit by the high voltage released by the rectifier, and cannot be lit when the voltage drops. The LED lamps can be lit within a certain range of voltage, and the brightness can be adjusted.
7. Save energy and have a longer lifespan
The power consumption of the LED fluorescent lamp is less than one-third of that of the traditional fluorescent lamp, and the lifespan is 10 times that of the traditional fluorescent lamp. It can be used for a long time without replacement, reducing labor costs. It is more suitable for occasions that are difficult to replace.
8. Strong and reliable, long-term use.
The LED lamp 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. Compared with ordinary fluorescent lamps, LED fluorescent lamps need no ballast, no starter, and no flicker.
10 Maintenance-free, frequent switching will not cause any damage.
11. Safe and stable quality, can withstand 4kv high voltage, low heat dissipation, can work at low temperature -30℃ and high temperature 55℃.
12. There will be no impact on the surrounding environment. There are no ultraviolet and infrared rays, no harmful materials such as mercury to protect the eyes, and no noise.
13. Good vibration resistance and easy to transport.
In addition, the world currently advocates energy saving and emission reduction. As a new type of energy-saving and environmentally friendly green light source products, LED fluorescent lamps will definitely replace traditional lamps in the future.

However, compared with ordinary fluorescent lamps, LED fluorescent lamps have the following disadvantages: they are expensive, and there is still a big gap between the luminous efficiency that can be generally achieved and the theoretical luminous efficiency, and there is still a big gap between the actual service life and theoretical life that can be achieved at present , And there is a certain amount of heat, and the light attenuation can be greatly reduced.
However, relatively speaking, LED fluorescent lamps have incomparable advantages over traditional fluorescent lamps. Not only are they highly efficient and energy-saving, they are also known as "longevity lamps", but they also have good applicability, small size, and are suitable for decoration. Low-carbon and environmentally friendly, no harmful qualities, can be recycled after disposal, brilliant colors, pure luminous colors, narrow spectral range, and using the principle of red, green and blue RGB three primary colors, under the control of computer technology, it can be mixed and matched at will Colors, light colors vary widely.
At present, most of the LED T-tube lamps on the market use semi-plastic and semi-aluminum shell materials, which are mainly composed of aluminum alloy and PC cover. Recently, in order to further reduce the cost, some manufacturers use glass materials to make the LED T tube lamp shell. The cost is only 50% of the cost of traditional semi-plastic and semi-aluminum LED T8 tube lights.
The cost of the glass tube LED fluorescent lamp meets the desire of many consumers to be "cheaper", but from the perspective of industry experts, in addition to being fragile, glass tube has a fatal weakness that can only be used for Retail market with low quality requirements.
The fatal shortcoming of glass tube LED fluorescent lamp is thermal management. Industry experts said that heat dissipation is a big problem facing glass tubes. He commented: “Take the 1.2m T8 tube as an example, the PC+aluminum design can really reach 18W, 120PCS 2835 LED. The lumen can be very high, and the stability is also very good. If you use glass tubes, as on the market now Yes, because of the fear of poor heat dissipation, it is often made with either insufficient power or very low lumen, or the warranty period is only one year. All of this is because if the glass tube is made of the same specification as aluminum, the lamp life will be obvious affected."
