The international standards of LED lamp beads include the following aspects:

Luminous flux: The luminous flux of LED lamp beads must comply with international standards, such as ISO 21118, CIE 127, etc.
Color: The color of LED lamp beads must comply with international standards, such as ISO 21118, CIE 127, etc.
Color coordinates: The color coordinates of LED lamp beads must comply with international standards, such as ISO 21118, CIE 127, etc.
Color rendering: The color rendering of LED lamp beads must meet international standards, such as ISO 21118, CIE 127, etc.
Lifespan: The lifespan of LED lamp beads must meet international standards, such as ISO 21118, CIE 127, etc.
Actual requirements may vary from application to application, for example, for automotive lighting applications, higher brightness, wider angle and longer life are required; while for decorative lighting applications, higher color quality and longer life are required. Long dimming depth.

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.

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.

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?
