Hello everyone, this afternoon a customer asked me if there is a specification sheet for 5mmled light-emitting diodes and a specification book for F5 round head lamp beads available?
Common light-emitting colors of 5mmled light-emitting diodes: red, green, white, green, yellow, orange, neutral white, warm white, positive white, cold white, and other light systems
The colloidal colors of F5 indicator light beads include: transparent, foggy, red, blue, green, yellow, and other colloidal colors
5mmled LED is a general conventional lamp bead, and its shape can be customized: straw hat, square, round head, ellipse, etc
Next, let's talk about the common basic parameters of circular lamp beads:
Working current 2.4-3.2V, power 0.06, luminous flux 10, Color index 80-90, specific 5mmled lamp beads have three parameters: monochrome, bicolor and tricolor
F5 round head lamp bead specification book. You can consult Hailongxing Optoelectronics for specific information. With 20 years of industry experience, we provide you with free testing and sampling, and provide the specification book

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?
