When selecting materials for the production of light boxes, appropriate materials should be selected according to the use environment, uses and specific requirements of customers. Light boxes can be divided into ultra-thin light boxes, cloth light boxes, card cloth light boxes, acrylic light boxes, rolling light boxes, electronic light boxes, EL light boxes, etc. .

The card cloth light box is favored by more and more consumers because of its high picture definition, easy operation to replace the canvas, and beautiful appearance. The card cloth light box is mainly composed of aluminum profile frame, LED light bar, light box backplane, power supply and canvas, etc. The following materials are introduced separately:

1. Aluminum profile frame: Aluminum profile frame is an indispensable material for making card cloth light boxes. According to the thickness, the commonly used ones are 4.5cm, 5cm, 6.5cm, 7cm, 8cm, 10cm, 12cm and so on.

Kabu light boxes are mostly used in indoor environments, such as shopping malls, mobile phone stores, cinemas, exhibition halls and other places. Among them, light boxes with a thickness of 5cm and 8cm are the most widely used. It can be customized according to different requirements for the size of the light box, the size is flexible, and the installation is very simple, so it is also the best choice for indoor light boxes.

2. LED light bar: LED light bar can be said to be the core of the card cloth light box and the most important part of the card cloth light box. The LED light bar used according to the thickness of the light box and the different requirements for the brightness of the light box is different. different.

For example, a card cloth light box with a thickness of 4cm-8cm, because the light box itself is relatively thin, it is suitable to use a diffuse reflection light bar, because the light beam angle of this light bar is 170°, which can effectively ensure the uniformity of the picture without shadows, and maximize the savings cost;

For the card cloth light box with a thickness of more than 8cm, 2835 or 5730 rolling shutter lights are suitable. The LED rolling shutter light bar has high brightness, uniform light emission, flexible size, simple installation and convenient maintenance, and is suitable for most light boxes.

3. Power supply (transformer): The LED light strips used in the card cloth light box are generally 12V/24V safe voltage, and cannot be directly connected to 220V, so a transformer is required. If it is 12V, use a 12V transformer, and 24V To use a 24V transformer, it should be noted that the power that the power supply can carry can only be about 80% of the rated power. For example, a power supply with a power of 400W can carry about 320W of power.

4. Kabu light box backplane: The material of the Kabu light box backplane is also divided into several types:

There are PVC boards (this product is made of polyvinyl chloride resin and stabilizer and other accessories after calendering and lamination, with high-quality anti-corrosion, insulation, temperature resistance and impact resistance, high strength, convenient secondary processing );

MDF (also known as fiberboard, which is a man-made board made of wood fiber or other plant fibers and applied with urea-formaldehyde resin or adhesive, with stable performance);

Aluminum-plastic panel (the chemically treated coated aluminum panel is the surface material, polyethylene plastic is used as the core material, and the composite material is processed on the special aluminum-plastic panel production equipment, with excellent fire resistance).

When choosing the back panel of the card cloth light box, you should choose the appropriate back panel according to the use environment of the light box. If it is directly installed on the wall, it can be installed without the back panel, and it can be directly hung on the wall, which is easy to operate and saves costs.

5. Card cloth light box screen: There are two main types of pictures used for card cloth light box:

Pearl cloth (pearl canvas, also known as waterproof non-woven fabric, belongs to inkjet photo cloth, is a textile coated fabric, the material is tightly woven, light in weight, soft to the touch, soft light effect is very good and non-reflective, UV inkjet effect is excellent, Good strength, strong anti-ultraviolet performance, bright colors, B1 class flame retardant, it is an excellent choice for making card cloth light box canvas).

UV soft film (soft film is made of special polyvinyl chloride material, 0.18

-0.2mm, weighs about 180~320 grams per square meter, and its fire rating is B1. The UV soft film is formed by one or more cuttings and completed by high-frequency welding). The price of pearl cloth is slightly higher than that of the UV soft film, which can be selected according to the actual situation.

The above is the introduction of the material for making the card cloth light box.
