[0017] The present invention will be further described below in conjunction with the drawings and embodiments.

[0018] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] As Figures 1 to 3 shown, this embodiment discloses a lamp string unit, which includes a lamp post and an upper cover 2 installed at the upper end of the lamp post. A light-emitting component 3 is installed inside the upper cover 2. The lamp post is at least divided into two cylinders from the outside to the inside. There are at least two groups of light sources on the light-emitting component 3. Each cylinder of the lamp post corresponds to each group of light sources on the light-emitting component 3 one by one. Each cylinder forms a light area. Each group of light sources is independently controlled, so that the lighting fixture realizes the effect of zoned light control, can be colored arbitrarily, has multiple lighting modes, and is fashionable and beautiful.

[0020] The lamp post is preferably a transparent lamp post and is made of materials such as acrylic and glass. The lamp post can also be semi-transparent. The lamp post is a multi-layer cylinder structure, and the light emission is more uniform.

[0021] In this embodiment, the lamp post is divided into three layers from the outside to the inside. The lamp post includes an outer cylinder 8, an intermediate cylinder 7, and an inner cylinder 6. The outer cylinder 8 has an inner hole with an opening facing the upper cover 2, and this inner hole is a blind hole. The intermediate cylinder 7 is placed in the inner hole of the outer cylinder 8, and the inner cylinder 6 is placed inside the intermediate cylinder 7. In this embodiment, the inner hole of the intermediate cylinder 7 is a through hole. The bottom surface of the intermediate cylinder 7 contacts the bottom surface of the inner hole of the outer cylinder 8 for positioning, and the bottom surface of the inner cylinder 6 also contacts the bottom surface of the inner hole of the outer cylinder 8 for positioning. The inner hole of the outer cylinder 8 being a blind hole is beneficial for moisture prevention.

[0022] The light-emitting component 3 is provided with three groups of light sources, and the three groups of light sources respectively face the outer cylinder 8, the intermediate cylinder 7, and the inner cylinder 6. The three groups of light sources are independently controlled, so as to have multiple light-emitting modes. In other embodiments, the lamp post is not limited to the three-layer structure of this embodiment, and two layers or more than three layers are also possible. The diameter of the inner hole of the outer cylinder 8 decreases from top to bottom, which is convenient for the intermediate cylinder 7 to be inserted therein. Similarly, the diameter of the inner hole of the intermediate cylinder 7 decreases from top to bottom, which is convenient for the inner cylinder 6 to be inserted therein.

[0023] The shapes of the outer cylinder 8, the intermediate cylinder 7, and the inner cylinder 6 are not limited. For example, the outer cylinder 8 can be square, circular, or other shapes, and the intermediate cylinder 7 and the inner cylinder 6 can also be square, circular, or other shapes. The shapes of the three can be the same or different.

[0024] The upper end of the outer cylinder 8 is provided with an external thread, and the inner wall of the upper cover 2 is provided with an internal thread. The outer cylinder 8 and the upper cover 2 are connected by threads. The connection method between the outer cylinder 8 and the upper cover 2 is not limited to this. For example, it can also adopt snap connection 41, screw connection, welding, gluing, etc.

[0025] A sealing ring 5 for closing the gap between the outer cylinder 8 and the upper cover 2 is provided between the outer cylinder 8 and the upper cover 2. When the outer cylinder 8 and the upper cover 2 are screwed tightly, the sealing ring 5 is tightly pressed by both of them. The sealing ring 5 is used for moisture prevention.

[0026] A diffuser 4 is further provided inside the upper cover 2 below the light-emitting component 3. The diffuser 4 covers the light source on the light-emitting component 3. The light-emitting component 3 includes a circuit board and light sources such as LED lamp beads mounted on the circuit board. The light source is mounted on the side of the circuit board close to the lamp post. The diffuser 4 is provided with a snap 41, and a slot 31 is provided at the corresponding position of the light-emitting component 3. The diffuser 4 is connected to the light-emitting component 3 through the cooperation of the snap 41 and the slot 31. The snap 41 is convenient and fast, and no tools are required. The connection method between the diffuser 4 and the light-emitting component 3 is not limited to this. For example, it can also be connected by screws.

[0027] A lamp head 1 for connecting a power cord is sleeved outside the upper cover 2. Both ends of the lamp head 1 can be connected to the power cord, so that multiple lamp string units can be connected in series.
