Description

Technical Field

[0001] The utility model relates to the technical field of lamp structures, in particular to an LED downlight structure. Background Art

[0002] The structure of LED downlight is mainly composed of driving power supply, light source chip, heat sink, lens and reflector cup, lampshade and other accessories. These parts work together to enable LED downlight to provide efficient lighting while maintaining good heat dissipation performance and light control. It is suitable for various indoor spaces, such as bedrooms, living rooms and bathrooms. Through different combinations of reflectors and lampshades, a variety of light effects can be achieved to create different atmospheres.

[0003] Once the light source of a downlight is damaged, the entire downlight can only be replaced. To replace the entire downlight, it is necessary to remove and reconnect the power line connected to the power grid. The steps for disassembly and assembly of LED light sources are complicated, which leads to the problem of disassembly and assembly being unchanged. Utility Model Content

Pulling the pull hole downward drives the triangular block, the vertical rod and the limit block to move downward, and drives the rubber card block to move out of the positioning groove, thereby releasing the fixation of the triangular block, and then releasing the fixation of the LED light source, so that it can be replaced. The LED light source is placed above multiple groups of triangular blocks, and the triangular blocks are pushed upward to drive the rubber card block into the positioning groove, so that the LED light source can be connected with the driving block.

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] Example 1

[0024] like Figure 1-4 As shown, the utility model provides an LED downlight structure, including a shell mechanism 2, a disassembly mechanism 1 is arranged inside the shell mechanism 2, a dustproof mechanism 3 is fixedly connected to the top of the shell mechanism 2, the disassembly mechanism 1 includes a driving block 11, a driving power source is arranged inside the driving block 11, a hollow limiting rod 12 is fixedly connected to the bottom of the driving block 11, a positioning groove 13 is symmetrically provided inside the hollow limiting rod 12, a limiting block 14 is slidably connected inside the hollow limiting rod 12, a vertical rod 15 is fixedly connected to the bottom of the limiting block 14, a triangular block 16 is fixedly connected to one side of the vertical rod 15, a pulling hole 17 is provided on the triangular block 16, a spring 18 is symmetrically arranged on the limiting block 14, one end of the spring 18 is fixedly connected to a rubber block 19, the rubber block 19 is fixedly connected to the surface of the limiting block 14, and the rubber block 19 is movably connected in the positioning groove 13, an LED light source 10 is arranged at the bottom of the driving block 11, and a handle 101 is fixedly connected to the upper surface of the driving block 11;

[0025] Specifically, when the LED light source 10 needs to be replaced, the handle 101 is rotated to drive the driving block 11, the hollow limiting rod 12 and the LED light source 10 to rotate synchronously, and the driving block 11 and the LED light source 10 are taken out of the lampshade 21. Then, the pulling hole 17 is pulled downward to drive the triangular block 16, the vertical rod 15 and the limiting block 14 to move downward, and then the rubber block 19 is moved out of the positioning groove 13, thereby releasing the fixation of the triangular block 16, so that the triangular block 16 is separated from the LED light source 10, and the LED light source 10 can be removed for replacement. Place the new LED light source 10 on top of the multiple sets of triangular blocks 16, push the triangular blocks 16 upward, drive the rubber block 19 to move synchronously, and make the rubber block 19 enter the positioning groove 13. After the pressure on the spring 18 disappears, an outward elastic force is applied to the rubber block 19, thereby improving the fit between the rubber block 19 and the positioning groove 13. Then, turn the handle 101 to drive the drive block 11 to rotate in the opposite direction, so that the drive block 11 is fixed inside the lampshade 21, and then the LED light source 10 can be installed, achieving the effect of convenient disassembly and assembly.

[0026] Example 2

[0027] like Figure 1-4 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the housing mechanism 2 includes a lampshade 21, a heat sink 22 is provided on the lampshade 21, a reflector 23 is provided inside the lampshade 21, and the driving block 11 is threadedly connected to the lampshade 21;

[0028] Specifically, the lampshade 21 is located outside the LED light source 10, and plays a role in protecting the LED light source 10, preventing debris from directly damaging the LED light source 10. At the same time, the lampshade 21 has an aesthetic effect, wrapping the internal parts to make the downlight look more beautiful. The heat generated inside the downlight when it is in use can be discharged outward through the heat sink 22, thereby preventing the internal temperature of the downlight from being too high. The reflector 23 can effectively concentrate and guide light, reduce light loss, and thus improve the utilization rate of light energy.

[0029] Example 3

[0030] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the dustproof mechanism 3 includes an upper cover plate 31, the upper cover plate 31 is fixedly connected to the top of the lampshade 21, a slide groove 32 is provided on the upper cover plate 31, a T-shaped rod 33 is fixedly connected to the upper cover plate 31, a connecting frame 34 is rotatably connected to the T-shaped rod 33, a dustproof net 35 is arranged inside the connecting frame 34, a slider 36 is fixedly connected to the bottom of the connecting frame 34, a threaded hole 37 is provided in the connecting frame 34, the slider 36 and the slide groove 32, and a positioning bolt 38 is threadedly connected inside the threaded hole 37;

[0031] Specifically, after the installation inside the downlight is completed, rotate the connecting frame 34 and the dust-proof net 35 to the right with the T-shaped rod 33 as the center, so that the slider 36 moves along the chute 32. When the dust-proof net 35 is located at the hollow of the center of the upper cover plate 31, stop rotating the connecting frame 34. Then, screw the positioning bolt 38 into the plurality of threaded holes 37, thereby connecting the connecting frame 34 and the slider 36 to the upper cover plate 31, and then cooperating with the T-shaped rod 33 to fix the dust-proof net 35, thus preventing dust from entering the inside of the downlight during use. Unscrew the positioning bolt 38 and slide the slider 36 to the left, then the connecting frame 34 and the dust-proof net 35 can be driven to move away from the hollow of the upper cover plate 31, and thus the replacement of the LED light source 10 is not affected.

[0032] Next, the working principle of the structure of this LED downlight will be specifically described.

[0033] As Figure 1-4 shown, place the LED light source 10 above the multiple triangular blocks 16, push the triangular blocks 16 upward, drive the rubber clamping blocks 19 to move synchronously, so that the rubber clamping blocks 19 enter the positioning grooves 13. After the pressure on the spring 18 disappears, an outward elastic force is applied to the rubber clamping blocks 19, thereby improving the fitting degree between the rubber clamping blocks 19 and the positioning grooves 13. Then, rotate the handle 101 to drive the driving block 11 to rotate in the reverse direction, so that the driving block 11 is fixed inside the lamp shade 21, and thus the LED light source 10 can be installed, making the LED light source 10 located inside the lamp shade 21.

When the dust-proof net 35 is located at the hollow of the center of the upper cover plate 31, stop rotating the connecting frame 34. Then, screw the positioning bolt 38 into the plurality of threaded holes 37, thereby connecting the connecting frame 34 and the slider 36 to the upper cover plate 31, and then cooperating with the T-shaped rod 33 to fix the dust-proof net 35, thus preventing dust from entering the inside of the downlight during use.

[0034] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
