3mm led direct plug lamp bead size
3mm led direct plug lamp bead size
The sizes of direct plug-in LEDs are divided into two pins: 2mm, 3mm, 4mm, 5mm, 8mm and 10mm. Small-sized lamp beads can be easily separated according to the size of the lamp beads. We have 3mm LED direct plug-in columns. 3mm plug-in lamp beads refer to the diameter of 3mm, its model is 3mm light-emitting diode, and its height is 5mm. It is divided into edged and edgeless.
The colors of the colloid include transparent, foggy, red, yellow, green, and blue lights. The specific wavelength can be customized according to your needs. Its wavelength is 600-635.
Luminous colors include: red, green, blue, yellow, two-color, three-color. Various light color effects can be customized
How many watts does a 3mm led plug-in lamp bead have?
Specifications: The general current is 20ma 0.06W and the working voltage is between 1.8-3.5v. Luminous flux: 100-120 lumens, color temperature: white light 6000-7000K.
The shapes of 3mmled direct plug-in lamp beads include: straw hat, round head, steel helmet head, high colloid, etc.
The main applications of 3mm plug-in lamp beads are: 3C electronics, industrial control panels, lighting, automotive electronics, and medical care.
According to your specific needs and lamp bead application scenarios. Further matching and options for your lamp beads, providing one-time solutions, providing customers with better selection and sales, and better reducing selection costs.
In general: Hailongxing Optoelectronics believes that as long as the customer's needs are clear and the application is relatively clear, the lamp beads specifically require better materials and better packaging types. In fact, it depends on the customer's product application needs. . Be people-oriented, not product-oriented, provide better solutions and more detailed services,
Each LED lamp bead manufacturer needs to manage its own customer base and whether it can provide better products and services in the long term. Putting quality first, making mid-to-high-end lamp beads, and enhancing the brand's core competitiveness are the future of Hilongxing Optoelectronics' development. Hailongxing has been focusing on the research and development, production and sales of light-emitting diodes for 17 years. We provide you with free testing and selection services to reduce costs and increase efficiency for win-win cooperation. Develop together
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?
