On the basis of the first structure of this embodiment, a lampshade 1 is added to the structure; the lampshade 1 has the same or similar structure compared with the second structure of Embodiment I, and so the lampshade 1 of this second structure of the second embodiment will not be described in detail here. It should be noted that, in this embodiment, depending on different shade bodies 11 for the lampshade 1 (as shown in FIGS. 15-18), the process steps of installing the lampshade 1 or the second lampholder body 216 will be slightly different, which will be explained in detail later. The difference between different shade bodies 11 mainly lies in a relationship between a maximum diameter of the shade body 11 and a diameter of the second opening 212.


In view of this, the production process of this structure is different from that of the first structure of Embodiment I only in that:


When the maximum diameter of the shade body 11 is less than the diameter of the second opening 212, the shade body 11 can pass through the second opening 212 along a direction from the first opening 211 to the second opening 212; with reference to FIGS. 15 to 16, step S3 will therefore comprise the following steps:


S31, forming a lampshade 1 by injection molding, wherein a shade body 11, an installation part 12, and an inner cavity 13 are simultaneously formed while forming the lampshade 1, and a second flange 121 is formed on the installation part 12;

    • S32, passing the two leads 4 through the channel 23 of the lampholder 21 in the first lampholder body 215 along a direction from the first opening 211 to the second opening 212, wherein part of the leads 4 extends out of the first lampholder body 215;
    • S33, electrically connecting the leads 4 extended out of the first lampholder body 215 in step S32 with the two poles of the LED 3 by welding;
    • S34, installing the LED 3 welded with the leads 4 in step S33 into the inner cavity 13, pressing the LED 3 welded with the leads 4 in the inner cavity 13 so that the first flange 31 of the LED 3 is in interference fit with an inner wall of the installation part 12;
    • or installing the LED 3 welded with the leads 4 in step S33 into the inner cavity 13, pressing the LED 3 welded with the leads 4 so that the first flange 31 of the LED 3 abuts against an end surface of the installation part 12;
    • S35, installing the lampshade 1 installed with the LED 3 and the leads 4 in the second lampholder body 216, pressing the lampshade 1 into the second opening 212 so that the second flange 121 abuts against the limiting platform 213;
    • S36, pressing the second lampholder body 216 against the first lampholder body 215, and connecting the first lampholder body 215 and the second lampholder body 216 by buckling.


When the maximum diameter of the shade body 11 is greater than the diameter of the second opening 212, the shade body 11 cannot pass through the second opening 212 along a direction from the first opening 211 to the second opening 212. In this case, with reference to FIGS. 17-18, step S3 comprises the following steps:

    • S31, forming a lampshade 1 by injection molding, wherein a shade body 11, an installation part 12, and an inner cavity 13 are simultaneously formed while forming the lampshade 1, and a second flange 121 is formed on the installation part 12;

Therefore, the installation part 12 can be deformed and pressed into the second opening 212;
    • S35, placing the LED 3 and the leads 4, which are welded to each other, into the second lampholder body 216, and further pressing the LED 3 and the leads into the inner cavity 13 so that the first flange 31 of the LED 3 is in interference fit with an inner wall of the installation part 12;
    • or placing the LED 3 and the leads 4, which are welded to each other, into the second lampholder body 216, and further pressing the LED 3 and the leads into the inner cavity 13 so that the first flange 31 of the LED 3 abuts against an end surface of the installation part 12;
    • S36, pressing the second lampholder body 216 against the first lampholder body 215, and connecting the first lampholder body 215 and the second lampholder body 216 by buckling.
