Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The directional terms mentioned in the present invention, such as "upper", "lower", "inner", "outer", etc., are only used to refer to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention. In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0027] like Figures 1 to 3 As shown, the present invention proposes a curtain wall system 100, which includes a curtain wall panel 1, a curtain wall column 2 and a curtain wall beam 3 arranged on one side of the curtain wall panel 1 for supporting the curtain wall panel 1, and at least one luminous decorative device 4 is arranged on the other side of the curtain wall panel 1.

[0028] Specifically, in this embodiment, Figures 3 to 5 As shown, the luminous decorative device 4 includes: a connecting plate group (not shown), a column 6 and a luminous decorative strip 7, the connecting plate group includes two connecting plates 5 longitudinally installed on the curtain wall system 100 and located on the same side of the curtain wall system 100; the column 6 is installed between the two connecting plates 5 in the connecting plate group; one end of the luminous decorative strip 7 is provided with a light-emitting portion 71, the other end of the luminous decorative strip 7 is sleeved on the column 6 and has a different installation angle relative to the column 6, and the luminous decorative strip 7 and the column 6 are connected by an angle fixing member 73 to fix the luminous decorative strip at a preset installation angle.

[0029] Compared with the prior art, the light-emitting decorative device 4 provided by the present invention is provided with a column 6 installed between two connecting plates 5 in the connecting plate group, and one end of the light-emitting decorative strip 7 away from the light-emitting portion 71 is sleeved on the column 6. The light-emitting decorative strip 7 has different installation angles at different installation positions relative to the column 6. After the light-emitting decorative strip 7 is adjusted to a preset installation angle, the light-emitting decorative strip 7 and the column 6 are connected by an angle fixing member 73 to fix the light-emitting decorative strip at the preset installation angle. When the light-emitting decorative device 4 provided with a plurality of light-emitting decorative strips 7 is used to decorate a curtain wall, complex shaping of the curtain wall can be achieved by adjusting the installation angle of the light-emitting decorative strip 7, and the reuse rate of the light-emitting decorative strip 7 is increased, and material waste is reduced.

[0030] In one embodiment, if Figure 4 and Figure 5 As shown, the column 6 is cylindrical, and the outer side surface of the column 6 is provided with a first rough structure, and the connection surface between the luminous decorative strip 7 and the column 6 is cylindrical, and the connection surface between the luminous decorative strip 7 and the column 6 is provided with a second rough structure that matches the first rough structure. When the luminous decorative strip 7 is sleeved on the column 6, it has different installation positions relative to the column 6, and the luminous decorative strip 7 has different installation angles relative to the curtain wall panel 1. The luminous decorative strip 7 installed on the curtain wall system can adjust the installation angle relative to the curtain wall panel 1 in the range of 0° to 180°. When the luminous decorative strip 7 rotates relative to the column 6 under the action of external force, the first rough structure and the second rough structure cooperate to increase the friction between the luminous decorative strip 7 and the column 6, so that when the luminous decorative strip 7 rotates relative to the column 6, it is easier to make fine installation angle adjustments and prevent the luminous decorative strip 7 from falling off the column 6.

[0031] In this embodiment, the first rough structure is a first sawtooth structure 61, and the first sawtooth structure 61 is evenly distributed on the outer surface of the column 6.
