Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] See Figs. 1 to 4 As shown, a multi-head chandelier with a lamp arm connection includes a ceiling plate 1, a lamp post 2 fixed in the middle of the bottom surface of the ceiling plate, a circular lamp holder 3 fixed at the bottom end of the lamp post, a power supply 4, a main light source board 5 and a light-transmitting lamp cover 6 fixed on the bottom surface of the circular lamp holder, and a plurality of mounting holes 7 fixed on the top surface of the circular lamp holder. In this embodiment, the lamp post can be a fixed-length lamp post or a telescopic lamp post with adjustable extension. Both are conventional structures in the prior art and are simply applied. The power supply and the main light source board are also structures in the prior art, so they are not described in detail.

[0031] In this embodiment, a plurality of lamp arms 8 are also provided, and a lamp structure 9 is fixed to the end of each lamp arm. One end of each lamp arm is fixed in a mounting hole by a screw. The lamp arm is an arc-shaped lamp arm or a wavy lamp arm. Furthermore, a through hole is provided inside the lamp arm for threading and connecting electrical wires.

[0032] In this embodiment, the lamp structure includes a hollow cylinder 91, an upper light source holder 92, an upper light source 93, an upper lampshade 94, a lower light source holder 95, a lower light source 96, and a lower light guide lampshade 97. In practical applications, the height of the hollow cylinder can be set as needed, while the upper light source holder has a funnel-shaped structure. The upper and lower light sources can be monochromatic or multicolor light sources, and the upper lampshade is made of glass or acrylic. The lower light source holder is a flat lamp holder or a spherical lamp holder. In this embodiment, the wires of the upper and lower light sources are connected to the power supply inside the circular lamp holder through the hollow cylinder and the lamp arm.

[0033] During assembly, the upper and lower light source bases are fixed to the top and bottom of the hollow cylinder, respectively. The upper light source is fixed to the top surface of the upper light source base, and the upper lampshade is connected to the top surface of the upper light source base. The light source from the upper light source base shines upward through the upper lampshade. The lower light source is fixed to the bottom surface of the lower light source base, and the top of the lower light guide lampshade is fixed to the bottom surface of the lower light source base. The light from the lower light source shines outward through the lower light guide lampshade. The end of the lamp arm can be rotatably inserted through the middle of the hollow cylinder. Through this structure, the upper light source base and upper light source can be inspected and maintained independently, as can the lower light source base and lower light guide lampshade. Furthermore, the angle of the hollow cylinder on the lamp arm can be adjusted as needed to achieve different angle illumination requirements.

[0034] In this embodiment, the lower light guide lampshade includes a light guide component 971, a first half-lampshade 972, and a second half-lampshade 973. The light guide component is a conventional material light guide component of the prior art, mainly used for guiding light. Furthermore, the light guide component includes a bottom hemispherical light guide component and a frustum-shaped upper light guide component integrally formed on the top of the bottom hemispherical light guide component. The top surface of the frustum-shaped upper light guide component is attached to the bottom surface of the lower light source base and fixed with screws. The first and second half-lampshades are fastened or glued together, and their combined shape is the same as the shape of the light guide component. The light guide component is located within the space formed by the combination of the first and second half-lampshades. Its design is aesthetically pleasing, and because the lower light guide lampshade includes a bottom hemispherical light guide component and a frustum-shaped upper light guide component integrally formed on the top of the bottom hemispherical light guide component, light will irradiate outwards from different positions of the light guide component during illumination, which helps to improve the uniformity and effectiveness of the irradiated light and enhances the lighting efficiency, thereby improving both the decorative effect and the lighting performance.

[0035] In this embodiment, the diameter of the upper lampshade matches the diameter of the top end of the light guide.

[0036] In practical applications, a circular hole is provided in the middle of the side wall of the hollow cylinder; an externally threaded protrusion 10 is provided at the end of the lamp arm; the externally threaded protrusion passes through the circular hole and is locked in place by a nut 11 after the installation angle is determined. This structure facilitates the connection and installation positioning of the hollow cylinder and the lamp arm end, and also allows for angle adjustment as needed. When adjusting the angle, the externally threaded protrusion is passed through the hollow cylinder, and the hollow cylinder is rotated by the corresponding angle centered on the externally threaded protrusion. Then, the nut is used to lock the end of the externally threaded protrusion, thus clamping and positioning the hollow cylinder, meeting the needs of different applications.

[0037] This utility model has positive effects: Its structure is rationally designed. A circular lamp holder is fixed to the bottom of the lamp post. A power supply, a main light source board, and a light-transmitting lampshade are fixed to the bottom surface of the circular lamp holder. A lamp arm is fixed to the circular lamp holder, and a lamp fixture structure is fixed to the end of the lamp arm. The lamp fixture structure includes a hollow cylinder, an upper light source holder, an upper light source, an upper lampshade, a lower light source holder, a lower light source, and a lower light guide lampshade. It can not only illuminate downwards through the main light source board but also provide illumination through the lower light source and the lower light guide lampshade. Furthermore, because the light guide component in the lower light guide lampshade includes… It includes a bottom hemispherical light guide and an integrally formed frustum-shaped upper light guide at the top of the bottom hemispherical light guide. When the light is guided, it will shine outward from different positions of the light guide, which helps to improve the uniformity and effectiveness of the illumination. The lower light guide lampshade can enhance the lighting decoration effect, and the upper light source and upper lampshade can also shine upward, improving the decorative illumination effect and meeting the needs of different situations. It also greatly enhances the overall decorative aesthetics, while facilitating the individual disassembly and maintenance of the lamp structure, reducing disassembly and maintenance costs.

[0038] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
