With the increasing demand for advertising light boxes, LED backlights (rolling shutter lights) have become an important light source for advertising light boxes. Traditional fluorescent tubes have inherent technical defects such as short life, poor protection, and easy damage. They cannot effectively meet lighting needs such as light box advertisements, shopping mall window advertisements, and platform advertisements. With the advantages of convenient installation and maintenance, it has become an irreplaceable high-quality light source in the advertising light box industry.

With the upgrading and improvement of advertising light box light bars, light box light bars have also been subdivided into two types of mainstream light sources, LED side light sources and LED backlight sources. Currently, these two types of light sources are most commonly used in advertising light boxes.

1. LED backlight (roller shutter light)

(1) User groups of rolling shutter lights

Large-scale advertising media companies (high-quality advertising space billboards, pedestrian streets in core business districts), large-scale well-known brand owners, enterprises (specialized store brands, brand image propaganda boards), etc.

(2) Different applications of rolling shutter light strips

If the thickness of the advertising light box is less than 8cm, it is recommended to use a diffuse reflection light bar. This kind of light bar has a lens and has a large light-emitting angle, so it can appropriately reduce the number of light bars arranged and the cost.

If the thickness of the advertising light box is 8cm or more, it is recommended to use ordinary rolling shutter light strips. The characteristics of rolling shutter light strips are that the size and spacing can be adjusted flexibly and arbitrarily to find a suitable light strip spacing to achieve the best light box lighting effect. .

(3) Lighting and installation of roller shutter light bars

The lighting of the roller shutter light bar should be adjusted according to the thickness and size of the light box. In order to avoid the ribs pattern when laying the lights, it is necessary to pay attention to the spacing of the light bar not greater than the thickness of the light box.

When installing the roller shutter light bar, pay attention to the positive and negative wiring. Generally, the gray line represents the positive pole, and the white line represents the negative pole; the positive and negative poles are connected to the DC output end of the power supply. , just replace it; in addition, the rolling shutter light bar is generally a low-voltage light bar, so be careful not to connect to the 220V end of the power supply, once the wrong connection, it will cause the lamp to burn.
