The gradual development of LED lamp beads
The gradual development of LED has gradually replaced some traditional light source products in public places such as lighting engineering assistance. In 2009, LED began to enter the mainstream lighting market in developed countries. In commercial applications where electricity costs are high and usage time is long, LED lighting fixtures have quickly become a new favorite in the market. As the use of LED lighting fixtures, the development of the LED market is divided into several stages.
The first stage is the practical model stage of LED lighting fixtures.
On the basis of the previous stage, the market has gained some recognition and acceptance of LED lighting products. The environmental protection, small size, high reliability and other characteristics of LED lamps are gradually becoming prominent. A series of products developed as a result that are completely different from traditional light source applications will become popular. The lighting industry will have a larger and broader development space. Light sources are no longer just for lighting purposes, their versatility makes them more suitable for every detail of people's work and life. Each manufacturer is competing for design application advantages.
The second stage is the intelligent control stage of LED lighting fixtures.
With the development of new technologies such as the Internet of Things, LED, as a Semiconductor industry, will also take this high-speed train to play its high controllability characteristics. From homes to office buildings, from roads to tunnels, from cars to walking, from auxiliary lighting to main lighting, LED lighting systems with intelligent control will bring higher levels of service to humanity. The LED lighting industry will also go through the process of producing products, designing products, and providing overall solutions.
The third stage is the acceptance stage of LED lamp replacement.
This stage refers to the early development of LED lamps, which mainly reflect their high light efficiency (low energy consumption) and long lifespan. Due to the high selling price, it is mainly in the commercial photography market at this stage. Customers have a process of acceptance, starting with the transition and acceptance of usage habits and appearance. In the same usage as traditional light sources, LED lamps exhibit characteristics such as power saving and longevity, making it easy for the market to accept their relatively high prices. Especially in commercial settings. All manufacturers are competing for quality and price advantages.

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?
