Welding method of LED lamp beads
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 beads change color? These six reasons are worth noting
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.
Common types and application fields of LED lamp beads
There are many kinds of LED light sources. Different LED lights have slight differences in the lamp beads used in their internal structures. Today, I will make a comprehensive and systematic scientific introduction to the common types of LED lamp beads for your reference.
LED lamp bead spectrum
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.
Full analysis of LED lamp bead structure
The LED lamp beads are mainly composed of five materials: bracket, silver glue, chip, gold wire and epoxy resin.
How to identify whether LED lamp beads are pure gold
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?
Holiday Notice of Hailongxing Optoelectronics Mid Autumn Festival
Welcome the Mid Autumn Festival to celebrate the National Day and the Mid Autumn Festival. The Mid Autumn Festival is coming. According to the actual situation of the company, the Mid Autumn Festival holiday arrangements of Hailongxing Optoelectronics Co., Ltd. are as follows:; The Mid Autumn Festival is a two-day holiday from September 20, 2021 (Monday) to September 21, 2021 (Tuesday). Work normally on September 22, 2021 (Wednesday). Please pay attention to protection during holidays. The epidemic situation is often not cut to the end, and protection cannot be less. The bright moon in the middle of the sky brightens the world. All good things are good, and people are reunited when the moon is full. Hailongxing Optoelectronics would like to send our best wishes to you and your family on the occasion of the Mid Autumn Festival: Happy Mid Autumn Festival and all the best!
Practice tells you the difference between 365nm and 395nm purple light beads
It is believed that many people are familiar with the purple flashlight, and the functions of 365nm and 395nm lamp beads are different. To put it simply: The light emitted at 365nm basically contains no purple, which does not affect the judgment. The purple color at 395nm is very strong, which sometimes affects the judgment. The fluorescence at 365nm is generally much stronger than that at 395nm; The fluorescence effect at 395nm is weaker than that at 365nm. 365nm can emit some fluorescence that cannot be emitted at 395nm, such as the fluorescence on the back of people people coins
The beauty of high lamp body lamp beads to the whole product
As long as the high lamp body lamp bead is applied to the electrical indicator, each electronic product lacks the indicator, which makes the product appear relatively simple, mainly because it cannot show the working process.
LED purple light has certain effect on sterilization
Long wave ultraviolet with a wavelength of 380~320nm is referred to as UVA, medium wave ultraviolet with a wavelength of 320~280nm is referred to as UVB, and short wave ultraviolet with a wavelength shorter than 280nm is referred to as UVC.
How much do you know about led beads
With the gradual development of LED lighting, LED has gradually replaced some traditional light source products in public places such as lighting engineering assistance. In 2009, LED began to popularize in developed countries. LED lamps have quickly become the new favorite of the market in the commercial application places where the electricity cost is high and the use time is long. As the use of LED lighting fixtures, LED market development is divided into several stages.

How to identify whether LED lamp beads are pure gold wire
The purity of gold wire used for packaging LED lamp beads is more than 99.99% gold. The gold wire made of this material is produced by wire drawing process. In addition to 99.99% gold, this gold also contains less than 1% of other trace elements. One of the core components of LED bead packaging is the gold wire, which is the bridge connecting the light-emitting chip and the welding point, and plays a decisive role in the service life of LED bead. So how to identify the purity of gold thread?
