Difference Between Copper Brackets And Iron Brackets

What are the differences between LED copper brackets and iron brackets?

What is an LED bracket:

 The LED bracket is formed by injecting PPA on the conductive metal surface to carry the LED chip and glue.The plating is generally a copper-silvered bracket.

The role of silver is to facilitate the light emission of the LED and the bonding with the LED gold wire, thereby making The LED chip and the LED bracket pins are

connected to form a loop, thereby causing the LED to emit light.

The function of LED bracket:

1. Carrying LED chips
2. Conductive effect
3. Diary function
4. Protect the internal structure of LED lamp beads

So what are the differences between LED copper brackets and iron brackets?

First, let’s take a look at the electrical conductivity and thermal conductivity of copper and iron:

We know that a major factor that affects LED life is the junction temperature of the LED lamp bead. The

higher the LED junction temperature, the shorter the life of the LED lamp bead. Correspondingly, the lower

the LED junction temperature, the longer the life of the LED lamp bead.

We know that a major factor that affects LED life is the junction temperature of the LED lamp bead. The

higher the LED junction temperature, the shorter the life of the LED lamp bead. Correspondingly, the lower

the LED junction temperature, the longer the life of the LED lamp bead.

In addition to the heat dissipation area, what affects the LED junction temperature is the resistivity of the LED

bracket and the thermal conductivity of the LED. The lower the resistivity of the LED, the higher the electro

optical conversion efficiency of the LED, the smaller the heat generation, the higher the thermal conductivity

of the LED, and the temperature difference between the interior of the LED and the radiator. The smaller it is,

the smaller the heat dissipation performance. We can see from the above table that the resistivity of the LED

iron bracket is 5.8 times that of the LED copper bracket, and the thermal conductivity of the LED copper

bracket is 5 times that of the LED iron bracket!

It can be seen that the life of LED lamp beads with copper brackets will be much longer than that of LED

lamp beads with iron brackets. At the same time, a major factor affecting the LED lamp death rate is the

ductility of the bracket. We know the ductility of copper. The ductility is many times better than that of iron,

which is enough to ensure that the retention rate of LED lamp beads with copper brackets is much higher

than that of iron brackets when subjected to cold and heat shocks!

Finally, there is another fatal flaw of the iron bracket, which is that it is easy to rust. When the iron rusts, the

silver-plated layer of the LED bracket will fall off, causing the LED lamp beads to break and die.

Summary: Copper brackets are much better than Iron brackets as hearafter

Better conductivity:

The conductivity of copper is also higher than that of iron, which makes the energy loss of LED lights with

copper brackets smaller during the current transmission process, improves the use efficiency of electrical

energy, and may also have an impact on the luminous efficiency of the lamp beads. promoted.

Higher reliability:

Since copper has better thermal stability and corrosion resistance, LED lights with copper brackets are more

resistant to the influence of various environmental factors, reducing damage caused by temperature changes

and corrosion, improving the overall LED screen reliability.

Longer service life:

Because copper has better thermal stretchability and metal fatigue, LED lamps with copper brackets have a

longer service life during the continuous switching process. Better thermal and electrical conductivity as well

as higher reliability help reduce the loss and failure rate of lamp beads, thereby extending the service life of

the entire display.
