[0042] See also Figures 1 to 9 The embodiment of the utility model provides a projection lamp string, including a plurality of projection lamp heads 1, wires 2 connecting the plurality of projection lamp heads 1, a controller 3 for controlling the light emission of the plurality of projection lamp heads 1, and a driving power supply 4 for driving the plurality of projection lamp heads 1 to work. The projection lamp head 1 includes a projection lamp body 11, an adjustment bracket 12, a surface-mounted fixing component 13, a binding fixing component 14, and a ground-inserted fixing component 15. One end of the adjustment bracket 12 is movably connected to one side of the projection lamp body 11 to adjust the illumination angle of the projection lamp body 11. The other end of the adjustment bracket 12 is provided with an assembly part 121. The assembly part 121 can be fixed to the surface-mounted fixing component 13, the binding fixing component 14, or the ground-inserted fixing component 15 according to different user environments. When the surface-mounted fixing component 13 is fixed to the assembly part 121, the surface-mounted installation is realized; when the binding fixing component 14 is fixed to the assembly part 121, the binding installation is realized; when the ground-inserted fixing component 15 is fixed to the assembly part 121, the ground-inserted installation is realized.

[0043] The above-mentioned projection light string is provided with an adjustable assembly part 121 and the matching surface-mounted fixing component 13, the bundling fixing component 14, and the ground-plug fixing component 15. By replacing different fixing components, three different installation methods can be realized, so that the projection light string can be compatible with a variety of installation environments. Whether it is a wall or a column that needs to be surface-mounted, or a scene that needs to be bundled on a railing or a tree, or a lawn or a courtyard that needs to be installed on the ground, the projection light string can respond flexibly, which greatly broadens the use scope and application scenarios of the projection light string products.

[0044] See also Figures 4 to 9 In this embodiment, the projection lamp body 11 includes a face shell 111, a heat sink 112 and a back cover 113 connected in sequence. A light outlet is provided on the face shell 111. A diffusion plate 114 is provided between the face shell 111 and the heat sink 112. A lamp board 115 is provided in the heat sink 112. The lamp board 115 is screwed into the heat sink 112 so that the lamp board 115 does not move. The heat generated by the light source is effectively dissipated through the heat sink 112, thereby ensuring the stable operation and long life of the projection lamp string. Three different light sources are provided on the lamp board 115, including RGB light source, white light source and warm light source. The light source is attached to the lamp board 115 through solder paste. The diversified light source configuration enables the projection lamp string to provide rich color changes and lighting effects according to different usage scenarios and needs. In addition, a reflective cup 116 is provided between the lamp board 115 and the diffusion plate 114, and the surface of the lamp board 115 attached with the light source is close to the reflective cup 116. The reflector cup 116 is conical, with the small diameter surface attached to the light board 115 and the large diameter surface attached to the diffuser 114. The light emitted by the light source is refracted through the conical surface to form a staggered light pattern. The above arrangement enables the projection light string to form a staggered color light pattern after lighting. At the same time, by using the light board 115 with multiple light sources, white light can be lit alone for lighting, and RGB color light can also be lit for festivals, so that the product has a larger market and a wider application space.

One end of the other wire 2 passes through its corresponding waterproof connector 16, the rear cover 113 and is connected to the other wiring terminal of the light board 115. The other ends of the two wires 2 are provided with waterproof female connectors / waterproof male connectors. The waterproof connector 16 has a waterproof function and can prevent moisture from penetrating from the connector. By providing waterproof female connectors / waterproof male connectors on the two wires 2, flexible electrical interface options are provided for the projection lamp head 1. According to actual needs, a waterproof male connector that matches the waterproof female connector can be selected for connection, or vice versa, so that the projection lamp heads 1 or the projection lamp head 1 and other electrical equipment or systems can be compatible and integrated, and can effectively prevent moisture or moisture from invading the connection parts.
