The Impact of Excessive Current on LED Advertising Screens

We all know that there are many methods to increase the brightness of LED advertising screens, such as selecting more energy-efficient LED chips, higher efficiency power supplies, and changing the current of LED advertising screens. However, excessive current can also affect the lifespan of LED advertising screens. Today, with LED advertising screen manufacturer China Ddon Visual, let's take a look at the impacts of excessive current on LED advertising screens:

1、Overheating and Failure: Excessive current can lead to overheating of LED screen components (LED lamps), which can result in the failure and shortened lifespan of the LED lamps. The normal operating temperature range for LED lamps is usually limited, and exceeding this range can cause damage.

2、Instability of Brightness and Colors: High current may cause brightness and color instability of the LED lamps on the advertising screen. The brightness and color of LED lamps are typically controlled by current, and excessive current may lead to brightness levels beyond the required range, resulting in color distortion or inconsistency.

3、Increased Energy Consumption: Excessive current will increase the energy consumption of the LED advertising screen, which can raise operational costs and reduce energy efficiency.

4、Shortened Lifespan: The lifespan of LED lamps is usually estimated based on their designed current. Excessive current can significantly reduce the lifespan of LED lamps, requiring more frequent replacements and increasing maintenance costs.

5、Safety Risks: High current can lead to circuit overload, which can pose electrical fire or other safety risks.

It's clear that excessive current affects LED advertising screens by causing overheating failures, instability in color and brightness, increased energy consumption, significantly shortened lifespan, and potential safety hazards. To ensure the longevity and proper operation of LED advertising screens, it's essential to find appropriate control methods rather than achieving it by increasing the current. Additionally, the power supply and control systems for LED advertising screens need to be designed and installed according to relevant standards and regulations to ensure safe and reliable operation of the product. The above information outlines the impact of excessive current on LED advertising screens, and we hope this article is helpful.
