Technical parameters of f3 red hair red lamp bead 3mm round head lamp bead
First of all, let's talk about what is f3mm round head LED light emitting diode. F3 round head lamp bead is another common light emitting diode. Compared with F5 round head lamp bead, its diameter is slightly smaller at 3mm. Suitable for applications with limited space or strict size requirements. Good luminous effect: 3mm round head LED can provide bright and uniform luminous effect, and is often used in indication and display applications. Low power consumption: One of the characteristics of LED technology is low power consumption, and F3 round head lamp beads also have low energy consumption.
3mm LED technical parameters and specifications
Size: F3 (diameter is 3mm)
Luminous color: F3 round head lamp beads can provide a variety of luminous color options, including red (red LED), green (green LED), blue (blue LED), yellow (yellow LED), white (white LED) wait.
Brightness: Brightness is usually expressed in terms of brightness level or luminous flux in lumens (lm).
Working voltage: The typical working voltage of F3 round head lamp beads is usually between 2V and 3.6V, depending on the type and specification of the LED lamp bead.
Operating Current: The typical operating current range is usually between 5mA and 20mA.
Angle of view: Angle of view refers to the range of light emitted from the lamp bead, usually expressed in degrees. Common viewing angles include 120 degrees, 140 degrees, etc.
Luminous Efficiency: Luminous efficacy indicates the light output produced per unit of power, usually expressed in lumens per watt (lm/W).
Lifespan: The lifespan of F3 round head lamp beads is usually measured in hours, and the specific lifespan depends on factors such as use conditions and quality
Electronic equipment: F3 round head lamp beads are widely used in indicator lights, switch button indicators, electronic clocks, remote controls, etc. in electronic equipment.
Car lighting: F3 round head lamp beads are often used in car interior lighting, such as dashboard lights, button lights, etc.
Home appliances and electronic products: F3 round head lamp beads are commonly used in display screens and indicators in household appliances and electronic products, such as TVs, refrigerators, washing machines, stereos, etc.
Lighting field: Although the brightness of F3 round lamp beads is relatively low, there is still room for application in some low-power lighting applications, such as small night lights and decorative lamps.

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?
