LED application fields
Light Emitting Diode (LED) Due to its advantages such as high efficiency, energy saving, long life, shock resistance, and quick response, light emitting diodes have replaced incandescent lamps from the beginning, and their colors also cover the entire spectrum from red to blue. have a wide range of applications. Here are some common LED applications:
Lighting: As a high-efficiency and energy-saving lighting source, LED is widely used in indoor lighting and outdoor lighting. LED bulbs, LED tubes, LED downlights, LED spotlights, etc. have become substitutes for traditional lighting products.
Landscape lamp beads
Display screen: LED display screens are widely used in indoor and outdoor billboards, large-screen TVs, stage backgrounds, stadiums and other places. The LED display has the characteristics of high brightness, high contrast, wide viewing angle and rich colors.
Automotive lighting: LEDs are widely used in the field of automotive lighting, including car lights, brake lights, turn signals, dashboard backlights, and interior lighting. LED has fast response, high brightness and low power consumption, which improves driving safety.
Car LED lamp beads
Backlight: LEDs are used as backlights for liquid crystal displays (LCDs). LED backlight has high brightness, high efficiency and uniform light distribution, and is used for the display of notebook computers, TVs, mobile phones and other equipment
Home appliances and electronic products: LEDs are widely used in various home appliances and electronic products, such as TV remote controls and screens. Electronic clocks, camera flashes, cell phone screens, video game consoles, etc.

Light Emitting Diode
There are many welding methods for LED lamp beads on the chip, and the following is one of the commonly used methods for reference. First, use an electric soldering iron to heat some soldering tin on the positive and negative electrode pads of the lamp bead (the soldering tin must not be too much, otherwise, the positive and negative electrode pads will be connected once heated with a hot-air gun), then use a hot-air gun to heat the positive and negative electrode pads at the same time, after the tin melts, use tweezers to place the positive and negative electrodes of the lamp bead on the corresponding pad.
LED is the light emitting diode, which is a semiconductor solid light emitting device that converts electric energy into light energy. Its core is the PN junction. In addition to the forward conduction, reverse cut-off and breakdown characteristics of the general PN junction, it also has the light emitting characteristics under certain conditions. Its structure mainly includes the following parts: lead, bracket, encapsulation glue, bonding wire, LED chip, solid crystal glue and phosphor. The discoloration failure of LED lamp bead is closely related to its material, structure, packaging process and service conditions. The following will analyze the causes of its discoloration through specific cases.
LED lamp beads are also called light emitting diodes. It has a wide range of applications. Its luminous colors include red light, emerald green light, yellow green light, yellow light, purple light, blue light, white light and orange light. The above is monochromatic light. It can also be made into two or three colors.
The gold wire used to package LED lamp beads contains more than 99.99% gold. It is produced by drawing gold from this material. In addition to 99.99% gold, this gold also contains less than 1% other trace elements. One of the core components of LED lamp bead packaging is gold wire, which is the bridge connecting the luminous chip and the welding point, and plays a decisive role in the service life of LED lamp bead. So how to identify the purity of gold thread?
