The light in nature is not the same, and the perceptible color of an object depends on the light source that illuminates it. The human brain can "correct" these color changes very

Eutectic welding is also called low melting point alloy welding. The basic feature of eutectic alloys is that two different metals can form alloys in a certain weight ratio at temp

Let's start with the concept of eutectic. The two fixed-component alloys, when melted into the liquid state, directly crystallize into two solid solutions with different components

The silicone grease applied on the LED lamp is actually different from the silicone grease on the CPU radiator. LED lights are generally used for a long time, especially for some o

At present, there are two kinds of circuit boards for LED lamps, one is aluminum substrate, and the other is glass soldering board. Next, I will analyze the difference between the

On October 7, the 2014 Nobel Prize in Physics was awarded to Akasaki Yuki, Amano Hiroshi and Nakamura Shuji. They successfully cultivated gallium nitride crystals for manufacturing

If you want LED lamp beads to play the best performance, not only need to start from the design, but also the chemical reactions that occur around the LED lamp bead products are al

The pure gold wire is drawn from a material with a gold purity of 99.99% or more, which contains trace elements such as Ag/Cu/Si/Ca/Mg. The silver thread is drawn from a material w

Gold wire, silver wire, alloy wire, and copper wire refer to the wires that connect the electrical connection between the LED chip (also known as the chip) and the external pins. O
