The difference between LED self-flashing lamp beads and IC controlled LED lamp beads
LED self-flashing lamp beads and IC-controlled LED lamp beads play different roles in the field of LED lighting. They have significant differences in principles, functions and applications. This article will compare the two from many aspects. 1. Principle and working method LED self-flashing lamp beads: These LED lamp beads have a simple circuit integrated inside them to periodically cut off and turn on the current. This causes the LED to flash at certain intervals, creating simulated flames, candles, etc. IC controlled LED lamp beads: These LED lamp beads achieve more precise lighting control by connecting to an integrated circuit (IC). The IC can adjust parameters such as LED brightness, color, and flashing patterns to achieve complex lighting effects. 2. Functions and effects LED self-flash beads: mainly used to generate basic periodic flashing effects. Due to its restrictive nature, it is mainly suitable for creating a specific atmosphere or decorative effect. IC controlled LED lamp beads: have richer functions and can achieve various colors, gradients, flashing frequencies, music response and other effects. Therefore, they can adapt to a wider range of lighting needs, including creative lighting, stage performances and more. 3. Application areas
LED self-flashing lamp beads: often used in decorative lighting, holiday lighting, interior decoration, etc., can add some interest to the scene. IC controlled LED lamp beads: widely used in stage lighting, commercial displays, building exterior decoration, etc., can create a variety of visual effects according to the needs of different scenes. 4. Flexibility and programmability LED self-flashing lamp beads: Their flashing patterns are usually preset, making it difficult to adjust or program changes in real time. IC controlled LED lamp beads: Due to the integrated programmable IC, the brightness, color, mode, etc. can be dynamically adjusted as needed, thereby achieving a more flexible and personalized effect. LED self-flashing lamp beads are mainly suitable for simple atmosphere creation, while IC-controlled LED lamp beads can provide more diverse, precise and creative lighting effects. Which type of LED lamp beads to choose should depend on the required lighting effect, application scenario and budget.

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?
