Is the light source of the light box and the led screen the same?

The light source of the light box and the LED screen is not the same. Light boxes usually use LED beads as their lighting source, but these beads are used to provide uniform backlight or direct lighting, such as in advertising light boxes, LED strips or scattered light sources are used to illuminate the advertising screen, making it clearly visible in a variety of light conditions. The LED screen, the full name of the light-emitting diode electronic display, is composed of many individually controlled LED pixels, each pixel can independently light up and display color, so as to display dynamic images and videos, which is essentially different from the static backlight lighting of the light box. The light source of the LED screen is designed to display digital content with high brightness, high resolution and rich color characteristics, suitable for playing dynamic visual information. Therefore, although both use LED technology, their application, luminous principle and purpose are very different.

Is the light source life of LED screen and light box the same?

Although both LED screens and light boxes use LED as a light source, their light source life may be different, mainly depending on the specific design, use environment and maintenance.

The light source life of LED screens is usually long, and the LED pixels of high-quality LED displays can reach a service life of 50,000 to 100,000 hours, or even longer. These screens are designed to work continuously for long periods of time, and modern LED technology focuses on energy efficiency and durability, so their light sources have a long life under ideal conditions.

The LED light source in the light box, such as the lamp strip or point light source, also has a fairly long life, generally between 30,000 and 50,000 hours, but because the light box may be used to display still images, its switching frequency may not be as frequent as the LED screen, which may have a positive impact on the light source life. However, the backlight design of the light box may make the LED use more concentrated in some areas, affecting the local life.

The actual life will also be affected by the use of the environment, such as temperature, humidity, voltage stability, etc. Good thermal design and regular maintenance can extend the service life of both light sources. In general, although both take advantage of the long life characteristics of LED, the LED screen may pay more attention to high stability and long life due to different technical requirements and use scenarios.
