What are the reasons why the LED illuminated letter string does not display characters clearly

In outdoor advertisements or shopping mall signs, we often see many LED illuminated string lights. These strings can attract consumers' attention. However, friends all know that this kind of product is a consumable and is prone to problems after being used for a period of time. On the street, we can see many strings breaking. Moreover, the font displayed is not so obvious. What are the fundamental reasons for this situation? We will further explain it to you in the following text.

What exactly causes the LED illuminated letter string to have a flickering effect? Under normal circumstances, the internal voltage of the LED illuminated letter should be within the rated range when it is working. However, due to a period of use, the internal resistance of the bulb has changed, but the voltage in the bus remains constant This leads to inconsistent voltage and current allocated to each small LED, resulting in some areas being bright while others are dark. Generally speaking, for such situations, they should be resolved by changing and connecting them in series.

If there is a problem with the LED illuminated letter light string, you can contact the manufacturer immediately. This way, you can get more comprehensive guidance. In fact, you should take better care of the product in daily life and avoid frequently turning it on, as this will affect the lifespan of the LED bulb. To ensure the more stable operation of this product, more effort should be put into installation. Generally speaking, when problems occur with the bulbs through parallel connection, it is easier to replace them separately without affecting the overall performance.
