The lifespan of LED advertising screens is affected by many factors. The factors that determine the lifespan of LED advertising screens mainly include the performance of LED light source devices, the quality of supporting components, the production process, and the working environment of the display screen.
- Impact of LED light source device performance:
LED lamp beads are the most critical component of the LED advertising screen, and their performance indicators directly affect the life of the advertising screen. 8 effects of LED lamp beads on LED display screens. Key indicators include:
Attenuation characteristics: The attenuation characteristics of LED light source devices determine the change of light source intensity over time.
Water vapor penetration characteristics: Good waterproof performance can prevent water vapor from penetrating and extend the life of LED lamp beads.
Anti-UV performance: Good anti-UV performance can prevent UV damage to LEDs.
- Impact of supporting parts:
The supporting components used in LED advertising screens include circuit boards, plastic casings, switching power supplies, connectors, casings, etc. Quality problems in any component may lead to a reduction in the life of the advertising screen. Therefore, the life of the advertising screen is restricted by the key components with the shortest life. What are the supporting equipment for LED display screens?
- The impact of production technology on products:
The production process of LED advertising screens directly affects its anti-fatigue performance. Inferior three-proof processing technology may cause cracks on the protective surface of the circuit board, thereby reducing the protective performance. Good production technology can improve the anti-fatigue performance of advertising screens and extend their life.
- Influence of the display working environment:
The working environment of LED advertising screens is an important factor affecting the lifespan. Different working conditions will cause the advertising screen to age at different rates. The temperature difference indoors is small and there is no influence from rain, snow and ultraviolet rays; while the temperature difference outdoors is large, coupled with wind, sun and rain, the harsh environment will aggravate the aging of the display screen. What is the difference between indoor LED display and outdoor LED display?
- Lifespan of LED lamp beads:
The life of LED lamp beads is usually defined as the time when the luminous intensity decays to 50% of the initial value. Although LEDs have a long life, due to differences in working conditions in actual use, the life may not reach the theoretical value. The life of the LED lamp beads determines the life of the advertising screen, but it does not mean that the life of the LED lamp beads is equal to the life of the advertising screen. The life span of the advertising screen should be many times that of the LED lamp beads, especially when the LED lamp beads operate at low current, the life span can be longer.
Therefore, maintaining the life of the advertising screen requires comprehensive consideration of the above factors and taking effective maintenance measures and a reasonable use environment to extend the service life of the LED advertising screen.
