The luminous principle of fluorescent lamp is to activate the mercury vapor in the tube by high voltage, so that the fluorescent powder on the lamp wall emits visible light. Fluorescent tubes generally include brackets, electronic ballasts, lamp bodies, plugs and other components. Although compared with incandescent lamps, fluorescent tubes are bright, energy-saving and have a longer service life, they also have some shortcomings, such as fragility, heavy pollution and stroboscopic, so they are gradually replaced by new light source LED tubes, and LED tubes are becoming the mainstream.

1. 1 About LED tubes

Led tubes are also called LED tubes, LED fluorescent tubes and LED fluorescent tubes. They use LED light source as light source. LED is a kind of semiconductor that can convert electric energy into visible light. It is different from incandescent tungsten filament and fluorescent powder of energy-saving lamps. Instead, it uses electric field to emit light and directly converts electric energy into light! Therefore, the light efficiency is higher and more energy-saving. In addition, it also has the advantages of pure light color, adjustable brightness and color temperature, no red and ultraviolet radiation, no mosquito attraction, no pollution, no stroboscopic and long service life. In addition, the appearance, size and interface of LED tubes are the same as those of traditional fluorescent tubes, so they are rapidly replacing fluorescent energy-saving lamps.

1.2 size

T5 and T8 tubes are commonly used, and their main differences are different diameters and different powers. The diameter of T5 tube is 16mm, the diameter of T8 tube is 25.4mm, and the common lengths are 0.3m, 0.6m, 0.9m,1.2m..

LED lamps, in addition to the previous split lamps, are also integrated lamps with lamp brackets due to the advantages of LED light sources, such as T5 and T8 integrated lamps, which can even be seamlessly connected with connectors! This is unimaginable for fluorescent tubes!

In addition to these types, LED tubes with acousto-optic control, human body induction, radar induction and other types have been born, which are more widely used and have better development prospects.

1.3 material technology and structure

As shown in the figure below, you can see the structure of LED tubes!

The LED lamp tube is mainly composed of seven departments: power supply, two-end interfaces, bracket, mask, fixing parts, LED light source and electrical contacts. The quality of LED tubes is mostly determined by workmanship and materials.

1.4 installation

The installation of LED tubes is very simple, because the diameter and interface are the same as those of traditional fluorescent tubes. Therefore, when installing, remove the original fluorescent tube and replace it with LED tube, and remove the ballast and upconverter, so that 220V AC mains can be directly added to both ends of the LED tube.

If the bracket lamp tube is integrated, connect the connecting wire directly! Lamp tubes can be connected by connectors to form a light band! What's more gratifying is that the connectable lamp tube without dark area has been born now!

1.5 application place

Lamps and lanterns are widely used, such as:

Houses, offices, conference rooms, office buildings, factories, etc.

Hospitals, schools, classrooms, libraries, government agencies and other public buildings and places.

Commercial lighting places, such as service halls, shopping malls, supermarkets, restaurants, bars, hotels, clubs, exhibition halls, etc.

Waiting hall, underground garage, subway, station, etc.

Gas station, chemical plant, granary and other dangerous spaces (explosion-proof)

1.6 About light colors

A remarkable advantage of LED is that it can realize a variety of light colors! LED tubes can also be white, warm white, natural white and other light colors, or cool, or white and elegant, or comfortable and warm.
