Referring to Fig. 1, Fig. 1 is a flowchart of the manufacturing process of the LED light source in the embodiment. The LED light source manufacturing process in this embodiment includes the following steps:

S1, obtaining a stent 1; the stent 1 has a receiving cavity 11;

S2, fixing the monochromatic light source chip 2 in the accommodation cavity 11 of the bracket 1;

S3, performing crystal solidification on the monochromatic light source chip 2;

S4, the bracket 1 is plastic-sealed in the plastic-seal cavity 31 of the mold 3. After plastic-seal, a lens 4 is formed on the accommodation cavity 11 of the bracket 1, and the lens 4 covers the monochromatic light source chip 2; the plastic-seal cavity 31 shapes the shape of the lens 4, so that The monochromatic light source chip 2 will be asymmetrically distributed around the central axis of the monochromatic light source chip 2 after the lens 4 has been shaped;

S5, obtaining an LED light source.

The lens 4 covering the monochromatic light source chip 2 is plastic-molded through the plastic sealing cavity 31, so that the lens 4 is better shaped, so that the monochromatic light source chip 2 will be shaped like the monochromatic light source chip 2 after the lens 4 is molded. The central axis is asymmetrically distributed. The prepared LED light source forms an LED display screen. After the LED display screen is installed perpendicular to the ground, the shaped lens 4 can make the light emitted by the monochromatic light source chip 2 tilt downward, which is more suitable for people who look up at a low place. This makes the displayed image clearer and the effect better when the viewer looks up.

2 to 4 together, FIG. 2 is a schematic structural diagram of the LED light source in the embodiment, FIG. 3 is a cross-sectional view of FIG. 2 in the embodiment, and FIG. 4 is an exploded view of the LED light source in the embodiment. In step S1, the number of accommodating cavities 11 on the bracket 1 is multiple, and the multiple accommodating cavities 11 are arranged in a line. When the number of accommodating cavities 11 on the bracket 1 is three, the three accommodating cavities 11 form a "product" Font arrangement; a plurality of monochromatic light source chips 2 are respectively arranged in a plurality of accommodating cavities 11 . The single-color light source chips 2 are separately accommodated in the plurality of accommodating cavities 11 , which can avoid interference between light sources of different colors, and can make the displayed image clearer when applied to a display screen. Preferably, a step 13 is formed on the side wall of the upper end of the bracket 1 , and the setting of the step 13 facilitates the synchronous formation of the sealing structure 43 when the lens 4 is molded into the accommodating cavity 11 .

In step S2, the monochromatic light source chip 2 is fixed in the housing cavity 11 of the bracket 1, and two methods can be adopted. One is to install the monochromatic light source chip 2 in the housing cavity 11 of the bracket 1, and realize the monochromatic light source chip 2 through wires. The electrical connection between the color light source chip 2 and the bracket 1 ; The above-mentioned forward rotation and inversion can adopt the existing technology, which will not be repeated here.

In step S3, the crystal-bonding process for the monochromatic light source chip 2 may also use an existing crystal-bonding process, which will not be repeated here.

Referring again to FIG. 5 , FIG. 5 is a schematic diagram of the plastic sealing process of the bracket in the plastic sealing cavity of the mold in the embodiment. In step S4, the bracket 1 is plastic-sealed in the plastic-seal cavity 31 of the mold 3, including the following sub-steps:

S41, the mold 3 is opened;

S42, putting the bracket 1 into the plastic cavity 31 of the mould;

S43, the mold 3 is clamped;

S44, inject glue into the plastic sealing cavity 31; the injected glue forms a lens 4 on the accommodation cavity 11 of the bracket 1, and the lens 4 covers the monochromatic light source chip 2;

S45, the mold 3 is opened;

S46, taking out the plastic-encapsulated bracket 1 .

In step S41, the mold 3 is divided into an upper mold 32 and a lower mold 33, wherein the shape of the lower mold cavity 331 of the lower mold 33 is adapted to the shape of the lower end of the bracket 1, so that the lower end of the bracket 1 can be placed on the lower mold correspondingly. 33 of the lower mold cavity 331, the upper mold cavity 321 of the upper mold 32 is adapted to the lens 4 to be shaped, so that the shape of the upper mold cavity 321 of the lens 4 is shaped, and the shaped lens 4 can make the monochromatic light source After the chip 2 has been shaped, the lens 4 will be distributed asymmetrically with the central axis of the monochromatic light source chip 2.

The cross-sectional area of the part above the surface of the receiving chamber 11 becomes gradually smaller. In this way, taking the central axis of the monochromatic light source chip 2 as the line of symmetry, the lens 4 forms curved surfaces with different shapes and different surface curvatures on the opposite side of the central axis of the monochromatic light source chip 2, and the light emitted by the monochromatic light source chip 2 passes through Different curved surfaces have different emission angles, and finally form the light that is distributed asymmetrically with the central axis of the monochromatic light source chip 2, so that the light of the monochromatic light source chip 2 is more concentrated on one side of the central axis. When the light source is installed vertically on the ground, the light of the LED light source can be inclined downward. When this type of LED light source is assembled to form a display screen, it is more suitable for people who are at a low place to look up.

In step S45, after the lens 4 is shaped successfully, the upper mold 32 and the lower mold 33 are opened. Then in step S46, the bracket 1 after the molded lens 4 is removed from the mold. Actions such as mold opening, mold closing, glue injection, and mold demoulding in the above steps S41 to S46 can refer to existing processes, and will not be repeated here.

Preferably, in step S44, while the injected glue forms the lens 4 on the housing chamber 11 of the bracket 1, the injected glue also covers the upper end of the bracket 1, so that an integrally formed seal is formed between the lens 4 and the bracket 1 structure43. Specifically, a step 13 is formed on the side wall of the upper end of the bracket 1 , which will be filled in the stepped space synchronously during glue injection. When the lens 4 is formed, a sealing structure between the lens 4 and the bracket 1 will be formed here. Through the design of the sealing structure 43, the protection of the LED light source is enhanced, and the weather resistance and outdoor service life of the LED light source are increased.

Preferably, in step S41 , the mold 3 is opened, and before that, it also includes: S40 , dispensing glue on the accommodation cavity 11 of the bracket 1 , and the injected glue is in the accommodation cavity 11 and covers the monochromatic light source chip 2 . That is, before step S44 is executed, glue is dispensed into the chamber 11 of the bracket 1 by dispensing glue, and the monochromatic light source chip 2 is covered in the chamber 11, so that when step S44 is executed, the monochromatic light source chip 2 can be firstly covered. The color light source chip 2 forms a protection to prevent air bubbles from being generated inside the accommodating cavity 11 when step S44 is performed.

In step S5, an LED light source is obtained. The bracket 1 of the plastic-encapsulated lens 4 is loaded with a control chip to realize that the electrical connection test is qualified.
