LED light strips are widely used in various advertising light boxes and other lighting places because of their long life, easy installation, safety and power saving. Among the reliability parameters of LED light box light bar, life is the most representative parameter. Therefore, the service life of LED light box light bars has become one of the most concerned issues in the industry. Whether it is for LED light box light bar manufacturers or users, it is necessary to understand the factors that affect the life of LED light box light bars. This article mainly briefly introduces several important factors that affect the life of LED light box light bars.

There are three main factors that affect the life of LED light box light bar:

1. The quality of lamp beads is the main factor that determines the life of LED strips

The quality of the lamp bead directly affects the service life of the LED light bar, so the lamp bead is very important for the LED light bar, and the lamp bead is composed of a variety of materials, and the quality of each material is also different, such as The brackets are divided into pure copper brackets, iron brackets, and aluminum brackets. The heat dissipation of pure copper brackets is of course better than that of iron brackets and aluminum brackets; the silicone material of the package and the gold wire connected internally are also very particular. Different brands of silicone The materials vary greatly, and the connecting wires are also divided into gold wires and gold-plated wires. Therefore, the quality of the lamp beads is inseparable from the quality of the raw materials used. A good and stable LED lamp bead must be the most stable combination of various materials.

The theoretical life of LED lamp beads can reach more than 100,000 hours. On the premise that the lamp beads are made of regular materials and the process packaging is guaranteed, the effective light decay life of LED lamp beads can reach 50,000 hours. However, due to improper competition in the market, some packaging factories choose inferior raw materials in order to reduce costs, which greatly affects the service life of LED strips.

2. The service life of the LED light box light bar is closely related to the heat dissipation of the aluminum substrate

The heat dissipation performance of the aluminum substrate directly affects a series of common problems such as the stability of the material structure of the LED light bar and whether the light decay is serious. Therefore, the heat dissipation performance directly affects the quality of the LED light bar. Even if the lamp beads are selected well, if the heat dissipation cannot keep up, the light attenuation of the LED strip will be serious. Therefore, whether to choose a high thermal conductivity aluminum substrate also plays a very important role in the life of the LED light bar.

3. The drive current of the LED light box light bar is greater than the rated current, causing serious light attenuation

The lower the driving current of the LED light box light bar, the smaller the heat and the lower the brightness. Therefore, some manufacturers will increase the driving current in order to pursue high brightness, and some even exceed the rated value that the LED lamp beads can withstand. Therefore, the LED lamp bead is overloaded, and the heat of the LED light box light bar increases linearly, which eventually causes the LED lamp bead to be unable to withstand the high load.
