For example, the light strings can be arranged into various required shapes, such as various Chinese characters, English characters, various specific graphics, etc., and by controlling the timing of the respective lamp body units 100 in the multiple light strings, a dynamic flashing effect can be achieved, thereby enhancing the atmosphere of festivals or event venues. In addition, different lamp body units 100 can also display different colors, thereby forming a colorful and gorgeous lighting effect.

[0026] When the light source 30 provided inside the spherical lamp housing 10 emits light, the light passes through the spherical surface of the spherical lamp housing 10 and is emitted from multiple different angles and directions, so that users can see the glowing spherical lamp housing 10 from all directions and angles. In addition, due to the adoption of the spherical lamp housing 10, correspondingly, a flexible or flexible printed circuit board 32 needs to be adopted to adapt to this curved surface shape, so as to install the circuit board 32 on the inner surface of the spherical lamp housing 10 by means of the flexible characteristics.

[0027] Generally speaking, due to the adoption of the spherical lamp housing, and a light source is provided inside the spherical lamp housing, the light source has a flexible printed circuit board, and a light-emitting unit is provided on the flexible printed circuit board. Therefore, by virtue of the specific three-dimensional shape of the lamp housing, the light emitted by the light source can be emitted from the surface of the spherical lamp housing at multiple angles, so that a single lamp body unit can produce a three-dimensional lighting effect, so that users can observe the lamp body unit with the same brightness from various different angles.

[0028] In the above embodiment, the preferred setting manner of the light-emitting unit is: a top wall 322 is formed on the flexible printed circuit board 32, and a side wall 324 is formed by bending along the edge of the top wall 322, and the light-emitting unit 34 is provided on the top wall 322 and / or the side wall 324.
