[0039] The following combines Figures 1 to 5 to illustrate the embodiments of the present utility model.

[0040] The thin chandelier assembly in this embodiment includes:

[0041] An aluminum profile main body 1, with an installation groove provided on the lower side. The top wall of the installation groove is provided with a first counterbore 102, the upper end of the first counterbore 102 penetrates through, and a plurality of heat dissipation channels 101 are formed in the aluminum profile main body 1. One end of the heat dissipation channel 101 communicates with the installation groove, and the other end communicates with the lateral side wall of the aluminum profile main body 1;

[0042] An LED lamp 2, which is locked in the installation groove by a first screw 6 provided at the first counterbore 102. The LED lamp 2 includes a light emitting surface 21 facing outside the installation groove; in this embodiment, circuit elements such as capacitors and inductors on the lamp board of the LED lamp 2 are hidden, and the bottom plate of the lamp board is locked on the aluminum profile main body 1 by a first screw 6 passing through the first counterbore 102.

[0043] The light guide bar 3 covers the side of the LED lamp 2 facing outside the installation groove, and the light guide bar 3 is snap-connected to the installation groove.

[0044] By providing a heat dissipation channel 101 communicating with the installation groove on the aluminum profile body 1, when the LED lamp 2 is working, the heat generated can be dissipated not only through the aluminum profile body 1 to the outside, but also through the heat dissipation channel 101. This improves the heat dissipation capacity of the thin chandelier assembly. When the thin chandelier assembly is designed with a relatively thin thickness, reducing the internal space of the thin chandelier assembly, the heat dissipation of the LED lamp 2 can still be ensured. Thus, a thin chandelier assembly with a smaller thickness and capable of continuous and reliable operation can be designed.

[0045] The aluminum profile body 1 is formed by splicing a first split body 11 and a second split body 12. The first split body 11 is provided with a first heat dissipation groove, and the second split body 12 is provided with a second heat dissipation groove. The first heat dissipation groove and the second heat dissipation groove are spliced to form the heat dissipation channel 101. The aluminum profile body 1 being set as a structure formed by splicing the first split body 11 and the second split body 12 can simply form the heat dissipation channel 101. In addition, the shape design of the heat dissipation channel 101 has a relatively large degree of freedom.

[0046] In order to increase the heat dissipation area, the heat dissipation channel 101 is in a serpentine shape. The serpentine heat dissipation channel 101 increases the contact area between the hot air and the aluminum profile body 1, which is beneficial to improving the heat exchange efficiency between the hot air and the aluminum profile body 1, and dissipating heat through the outer wall of the aluminum profile body 1.

[0047] In order to reduce the light leakage phenomenon, a light extinction structure is provided in the heat dissipation channel 101. Setting a light extinction structure in the heat dissipation channel 101 can reduce the escape of the light of the LED lamp 2 through the heat dissipation channel 101, thus causing the problem of light leakage in the thin chandelier assembly.

[0048] Specifically, the heat dissipation channel 101 includes a plurality of corners 1011, and the light extinction structure is provided at the corners. The light extinction structure includes a first arc-shaped wall 1012 and a second arc-shaped wall 1013. The first arc-shaped wall 1012 and the second arc-shaped wall 1013 are respectively formed by the outer concave of the two side wall surfaces of the corner. The first arc-shaped wall 1012 and the second arc-shaped wall 1013 are in a wedge shape. By providing the first arc-shaped wall 1012 and the second arc-shaped wall 1013 at the corner to form a light extinction structure in a wedge shape, when the light falls on the first arc-shaped wall 1012 and the second arc-shaped wall 1013, it needs to be reflected multiple times to escape, effectively reducing the light intensity.

[0049] The thin chandelier assembly further includes a first gasket 4 and a second gasket 5. The first gasket 4 and the second gasket 5 are respectively pressed into the left end and the right end of the installation groove. Both ends of the light guide bar 3 are respectively abutted against the first gasket 4 and the second gasket 5. The first gasket 4 and the second gasket 5 are both soft gaskets. In the thin chandelier assembly of this embodiment, the installation groove is an elongated groove, and there are likely to be certain dimensional errors during processing. The first gasket 4 and the second gasket 5 are filled on both sides of the installation groove to form a soft limit on the inner side of the installation groove. When the light guide bar 3 is pressed into the installation groove, it is easier to keep it tightly pressed in the installation groove.

[0050] The thin chandelier assembly further includes a chandelier base 9 and a connecting suspension wire 8. One end of the connecting suspension wire 8 is connected to the chandelier base 9, and the other end of the connecting suspension wire 8 is fixedly connected to the aluminum profile body 1. The chandelier base 9 is installed on the ceiling. The chandelier base 9 suspends the aluminum profile body 1 in the air through the connecting suspension wire 8, and a top light source is formed through the light guide bar 3 below the aluminum profile body 1 for lighting.

[0051] A first pin 111 is provided on the first split body 11, and a positioning hole 121 is provided on the second split body 12. The first pin 111 is inserted into the positioning hole 121. The first pin 111 is designed on the first split body 11, and the positioning hole 121 is provided on the second split body 12. When the first split body 11 and the second split body 12 are assembled, positioning can be performed by inserting the first pin 111 into the positioning hole 121, thereby improving the assembly accuracy.

[0052] A screw hole 1111 is provided on the first pin 111. The positioning hole 121 penetrates through the second split body 12. The positioning hole 121 is a counterbore. A second screw is provided at the positioning hole 121. The second screw passes through the positioning hole 121 and is threadedly connected to the screw hole 1111.

[0053] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments.
