3mm blue-haired blue in-line LED, 3mm blue-haired blue plug-in lamp beads
3mm blue-haired blue lamp bead "LED lamp bead is a semiconductor device, also known as f3LED lamp bead. It is a blue LED (light-emitting diode) lamp bead with a diameter of 3 mm. Blue colloid, the color temperature of the product band is: 455-475NM , can emit blue light. Using silver-plated iron, gold wire, environmentally friendly high-temperature resistant glue, it is often used in indicator lights, display screens, lighting and other applications. Hailongxing Optoelectronics is a manufacturer of led light-emitting diodes.
3mm blue hair blue classification: round head, flat head, bump, straw hat, etc.
The shape is a round head, 3MM round head with brim lamp beads, and no brim lamp beads. Long and short feet. The lamp pins are mainly selected according to the scene. His colloid colors are: red, yellow, blue, mist, transparent, green, etc. Luminous brightness: 400-600MCD, working life of 5000 hours with long service life.

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?
