When installing the LED injection molding module, you will encounter various problems, which can be summarized as the following problems. details as follows:

(1), the thickness of the box

The thickness of the box should be between 4cm and 12cm, which can ensure the uniformity of light and the best brightness. When choosing acrylic sheets, pay attention to uniform thickness and good light transmission effect.

(2), the arrangement of modules

Generally, we recommend that customers arrange injection molding LED modules with a horizontal spacing of 3cm and a vertical spacing of 3cm (module-to-module distance). If the light box is too far away, there will be dark areas or black shifts when it is bright.

Light box (length X width) ≈ 120 pieces/square meter

Chinese characters (character height X character width) ≈ 80 blocks/square meter

English characters (character height X character width) ≈ 60 blocks/square meter

Stroke width is 5cm, 1 line/stroke

Stroke width is 10cm, 2 lines/stroke

The distance between the module and the font edge is recommended to be 4-6CM

In actual operation, it should be adjusted according to the height of the box and the material of the panel to achieve the desired effect. In order to ensure the uniformity of luminous intensity, when installing and arranging the LED injection molding modules, attention should be paid to the uniform and reasonable distribution of the luminous modules.

Precautions

1. The number of modules connected in series at the power port should not exceed 20, otherwise the tail module will decrease in brightness due to voltage attenuation, and the formation of a loop can avoid the occurrence of attenuation.

2. When the LED injection molding module without waterproof treatment is installed in the font or box, rainwater should be prevented from entering the font or box.

3. The spacing of injection molding modules can be adjusted according to the brightness requirements, and the distribution of points per square meter is best controlled between 40 and 70 groups.

3. When the power cord is connected to the box, it must first be connected to the corresponding four or three groups of injection molding modules through a quarter or three-point line. After the power cord enters the box, a large knot should be tied to prevent it from being pulled off by the force outside.
