The difference between three color inline lamp beads and two color inline lamp beads
Hello everyone, I am the editor of Hailongxing Lamp Beads Factory. Yesterday afternoon, a customer asked me if the length of the two color straight in lamp beads is the same as that of the three color straight in lamp beads? What is the difference between them?
Three color LED direct insertion lamp beads are generally co negative or co positive, with three colors added and four intersecting together
Dual color LED plug-in lamp beads, usually co negative or co positive, with two colors added and three legs together
The three color inline LED is mainly used in backlight modules, signal indicator lights, automotive ambient lights, smart furniture, digital accessories and other products. Today we have a 3mm round head three color common female round head straight in LED as a column
Dual color LED light beads with both yin and yang, usually red and blue, red and green, and red and emerald green, are mainly used in automotive interiors and on smart home indicator light beads
Dual color lamp beads have the characteristics of energy conservation, high brightness, long lifespan, and low attenuation. Today, we have taken 3mm dual color co cathode co anode direct insertion lamp beads as an example
The length of the three color co yin co yang direct insertion lamp beads and the two color direct insertion lamp beads are similar, mainly determined by their brackets. LED lamp bead brackets are generally universal, and in design, a more universal bracket length is generally used
The long ones are generally 29mm, while the short ones are around 27mm25mm
In practical applications, after the assembly of our plugins, the excess length is usually cut off to ensure the normal trial use of the product structure
Today, we will share the management of dual color direct plug-in LED light beads and three color plug-in light beads. We hope it will be useful to you. If you want to buy light beads, please contact Hailongxing and we will solve it for you 24 hours a day. If you still need to know about LED chip mounted light beads, direct plug-in LED high-power LEDs, you can leave us a message

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?
