Embodiment 1

[0020] Example 1, a plastic downlight structure, refer to figure 1 and image 3 . The downlight of the present invention includes a plastic lamp housing 1, a lamp board 2 installed in the lamp housing 1, LED lamp beads 3 and lead wires 4 welded on the lamp board, and the astigmatism covering the light outlet of the lamp housing 1 plate 5. The lamp housing 1 has a circular bottom wall 11 and a cylindrical side wall 12 surrounding the bottom wall 11 . Several positioning columns 13 are arranged on the bottom wall 11 , and wire outlet holes 14 are arranged on the side wall 11 . The lamp board 2 is provided with a plurality of positioning holes 21 corresponding to the positioning columns 13 . refer to Figure 4b . The positioning post 13 is inserted into the positioning hole 21 , and the upper end of the positioning post 13 is provided with an anti-off portion 131 that prevents the lamp panel 2 from sliding out. The positioning column 13 and the positioning hole 21 are arra...

Embodiment 2

[0023] Embodiment 2, a metal downlight structure. refer to figure 2 . The difference between embodiment 2 and embodiment 1 is that the lamp housing 1 is made of metal material, and the bottom wall 11 of the lamp housing 1 is provided with several installation holes 15 . refer to Figure 6b The positioning column 13 is a T-shaped plastic part made independently, including a column body 130 and a column head 132 arranged at one end of the column body 130 with a diameter larger than that of the installation hole 15 . The column body 130 passes through the installation hole 15 of the bottom wall 11 and the positioning hole 21 of the lamp panel 2 sequentially from the outside of the lamp housing. The column head 132 is clamped on the outer side of the bottom wall 11 of the lamp housing, and the anti-loosening part 131 is clamped on the lamp board 2 , and the two clamp and fix the lamp board 2 on the bottom wall 11 of the lamp housing.

Embodiment 3

[0026] Embodiment 3, a metal downlight structure. refer to figure 1 , image 3 and Figure 8b . The difference between Embodiment 3 and Embodiment 1 is that the lamp housing is made of metal material, and the positioning column 13 is a stretched part integrally formed with the bottom wall 11 by partial punching from the outside to the inside of the bottom wall 11 of the lamp housing. structure, the anti-loosening portion 131 is a thick and deformed structure formed by stamping the top end of the positioning post 13 .

[0027] The manufacturing method of the metal downlight described in Embodiment 3 includes the manufacturing process of the lamp housing, the manufacturing process of the lamp panel and the assembly process of the lamp panel. The manufacturing process of the lamp housing includes using a stamping process to manufacture a metal lamp housing, and at the same time stretching the bottom wall 11 of the lamp housing from the outside to the inside to form a position...

Abstract

A manufacturing method of a down lamp comprises a lamp shell manufacturing process, a lamp panel manufacturing process and a lamp panel assembling process, and the lamp shell manufacturing process comprises the steps that a metal lamp shell with a bottom wall and side walls is manufactured through a stamping process, and a plurality of positioning columns are arranged on the bottom wall of the lamp shell; the lamp panel manufacturing process comprises the steps that positioning holes corresponding to the positioning columns are formed in a lamp panel; the lamp panel assembling technology comprises the steps that the positioning columns are sleeved with the positioning holes of the lamp panel, then the top ends of the positioning columns deform, and anti-disengaging parts for preventing the lamp panel from disengaging are formed. The positioning columns are arranged on the bottom wall of the lamp panel, the positioning holes matched with the positioning columns are formed in the lamp panel, the lamp panel is sleeved with the positioning columns through the positioning holes to be assembled and positioned, the anti-falling parts are formed at the top ends of the positioning columns to fix the lamp panel, the positioning columns achieve the functions of positioning and fixing the lamp panel at the same time, and the lamp panel fixing structure has the advantages of being convenient to position, simple in fixing structure and high in practicability. Manual operation is less, assembling efficiency is high, and automatic production is facilitated.

Description

technical field [0001] The invention relates to a lamp, in particular to a method for manufacturing a downlight. Background technique [0002] The structure of the existing downlight includes a lamp housing, a lamp board is installed in the lamp housing, LED lamp beads and lead wires are welded on the lamp board, and outlet holes are arranged on the side wall of the lamp housing. The bottom of the lamp housing is provided with several positioning posts and threaded holes, and the lamp panel is provided with several positioning holes corresponding to the positioning posts. Align the position with the outlet hole so that the lead wire can pass through the outlet hole, and then manually screw the screw through the lamp plate into the threaded hole at the bottom of the lamp housing. Therefore, the existing downlights have the disadvantages of complex installation and positioning, low work efficiency and unfavorable automatic production. Contents of the invention [0003] In ...
