Have you seen the ribs and dark spots on the light box? This is the problem of the light source of the light box. What light source was used for the light box in the past? The commonly used light source on the light box is the fluorescent tube t4/t5/t8. If the thickness of the light box is large, such as more than 25cm, T8 fluorescent tube can be used. Use T4 or T5. Due to more and more problems in the use of light boxes, fluorescent tubes are gradually replaced by LED light bars. At present, the most widely used lighting sources in the field of light box lighting are LED side light sources and LED backlight sources.

Why not use t4/t5/t8 fluorescent tubes as the light source for light box lighting:

(1) The installation process of fluorescent tubes is more troublesome

When the fluorescent tube is used for the installation of the light box, the lamps need to be fixed one by one, and the spacing between the lamps should be relatively densely distributed. If the spacing is too large, there will be problems such as ribs and insufficient brightness. Small, it will increase the cost of materials and labor costs of installation, and if there is a problem in the subsequent use process, maintenance and replacement are also more troublesome.

(2) Short life, serious light decay after long-term use, frequent replacement is required

Generally, the life of t4/t5/t8 fluorescent tube is about 10,000 hours. Long-term use will cause the ends of the lamp to turn black, resulting in a decrease in the brightness of the lamp and serious light decay, and the fluorescent lamp cannot be started frequently. , which is equivalent to burning for two hours. Because every time it is started, the two cathodes will be impacted by a high-voltage pulse, which will increase the consumption of electron-emitting materials on the cathodes. When the electron-emitting materials on the filament are exhausted, the lamp tube will be scrapped. Replace with new fluorescent tubes.

(3) High energy consumption and easy damage

The power consumption of fluorescent tubes is two-thirds higher than that of LED strips, and at the same brightness, 9W LED strips save more than 50% of power than 18W traditional fluorescent lamps. Moreover, the lamp body of the fluorescent tube itself is made of traditional glass material, which is a fragile product. During the installation process, special care should be taken to handle it with care, as it will cause damage if you are not careful.

The above is a description of the disadvantages of fluorescent tubes.
