Introduction of manufacturing method and technical principle of LED light string

On some outdoor billboards or signboards, we often find many led light strings dotted with rich colors, which can make unpredictable effects according to different times and achieve the advantages of beauty and practicality. So, what's special about this LED string compared with ordinary lamps? What are the specific production methods? Interested friends can refer to the following to understand the production methods and skills of led light strings, in addition to the popular science materials of technical principles.

First, the technical principle of LED light string

There is an integrated chip oscillator circuit inside the LED, and its appearance is no different from that of the general LED. As long as the power is turned on, the two colors will light up in turn, 1 sec 1 change. I bought a 5MM red and blue flash. From the appearance, it is a series, but it is not necessarily a series.

LED light string:

Light-emitting diode is called led for short. Made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc.

When electrons recombine with holes, they can emit visible light, so they can be used to make light-emitting diodes. Used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light and gallium nitride diodes emit blue light. Because of its chemical properties, it can be divided into organic light-emitting diode and inorganic light-emitting diode LED.

Second, the manufacturing methods and skills of led light string:

Attention must be paid to the positive and negative poles of LED light string in the manufacturing process to ensure correct connection. Its production is composed of monochromatic light strings.

1. Monochrome light string production? Including monochrome optical string plug-in and wiring, very simple. When inserting, just insert the light string into the corresponding hole, and then connect it in a certain order when wiring. At the same time, pay attention to the positive and negative poles of all light strings and try to ensure them together. Connect the positive electrodes together, and then lead out the positive electrode wire. Similarly, connect the negative electrodes together and lead out the negative wire.

2.LED string? After the test, all light strings should be lit, and various connections should be tied separately and kept fixed. Then, the wiring part should be marked with waterproof glue, thus completing the production of LED light string.

The above examples are popular materials about the manufacturing methods, attention skills and technical principles of led light strings, from which we can know that these products are mainly used in some advertising fields, such as outdoor billboards or signboards of some businesses, and colored led light strings are often used. In addition, they can also achieve the effect of beautiful decoration in some festivals. Further, we can find that it is relatively simple to make led light strings by ourselves, as long as we master the principle and understand relevant aspects.
