[0027] The present utility model provides a lamp arm assembly 100, aiming to be compatible with the installation of lamp poles of at least two calibers, reduce the installation cost, and improve the installation and maintenance efficiency.

[0028] Please refer to Figure 1 and Figure 2 In one embodiment, the lamp arm assembly 100 includes a lamp support arm 1. The lamp support arm 1 is provided with at least two mounting cavities that have different cross-sections, different radial dimensions, penetrate through the same end of the lamp support arm and are coaxially arranged, and are used for installing lamp poles of at least two caliber sizes.

[0029] Specifically, the lamp support arm 1 is a tubular structure with one end (i.e., the end for assembling the lamp pole) open. At least two coaxially arranged mounting cavities are defined inside it. The mounting cavities are located in two different cross-sections and have different radial dimensions. The bottom wall of the mounting cavity with a smaller radial dimension is located on the side of the bottom wall of the mounting cavity with a larger radial dimension away from the open end of the lamp support arm. The side wall of the mounting cavity with a smaller radial dimension is located inside the side wall of the mounting cavity with a larger radial dimension. The radial dimensions of different mounting cavities are adapted to the radial dimensions of lamp poles of different caliber sizes. With such a setting, the mounting cavities with different radial dimensions can be adapted to install lamp poles of different caliber sizes, and the versatility of the lamp arm assembly is relatively high.

[0030] The lamp arm assembly 100 provided by the present utility model can be compatible with the installation of lamp poles of at least two calibers, has relatively high versatility, effectively reduces the installation cost, and improves the installation and maintenance efficiency.

[0031] It should be noted that the number of mounting cavities provided can be determined according to the radial dimension of the lamp support arm 1, specifically depending on the actual situation. Here, taking the setting of two mounting cavities as an example, the lamp arm assembly 100 provided by the present utility model will be described in detail.

[0032] Please refer to Figure 1 and Figure 2 In a specific embodiment, the lamp support arm 1 includes a connected support portion 11 and a fixing portion 12.
