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

Introduction to the causes of damage to LED lamp beads and protection methods White LED lamp beads are voltage-sensitive devices. In actual work, the current is 20mA as the upper l

In the PCBA processing industry, due to the small size of SMD LEDs, low power consumption, long service life, high brightness, environmental protection, sturdiness and durability,

The invention of blue LED (light emitting diode), which has been considered difficult to achieve for many years, gave birth to energy-saving and long-lived lighting fixtures and di
