Preferably, the number of the first mounting portions 23 is at least two, and the at least two first mounting portions 23 are disposed in one-to-one opposition to the at least two reflecting surfaces 14. After the plurality of first light source assemblies 30 are respectively mounted on the first mounting portions 23, each first light source assembly 30 has a reflecting surface 14 for reflecting the light emitted by the first light source assembly, so that the light of the whole lamp is more uniform, the light and shade difference is eliminated, and the glare problem of the whole lamp is improved.

Preferably, as shown in fig. 5, the inner surfaces of the second ends 222 of the two side plates 22 are provided with first grooves, the two first grooves are disposed opposite to each other, and the two first grooves enclose the plugging space 26. The plugging space 26 may be used for installing a light distribution plate, and the light distribution plate may be a diffusion plate or a prism plate or both. Because the second mounting portion 24 is disposed on the inner surface of the second main housing 21, after the light distribution plate is mounted in the plugging space 26, the light distribution plate is disposed opposite to the second mounting portion 24, and after the second light source assembly 40 is mounted on the second mounting portion 24, the second light source assembly 40 is disposed opposite to the light distribution plate, and the light distribution plate mounted in the plugging space 26 can perform overall light distribution on light emitted by the second light source assembly 40, and meanwhile, materials of the light distribution plate can be saved. In this embodiment, the first groove is formed on the side plate 22 for installing the light distribution plate, so that the installation portion is not required to be additionally arranged on the light outlet 15 of the first housing 10 to install the light distribution plate, which is beneficial to reducing the height of the lamp housing, so that the requirement of the lamp housing of this embodiment on the installation environment height can be reduced.

When the second light source assembly 40 is mounted on the second mounting portion 24, both mounting holes 121 are located on the light emitting side of the second light source assembly 40. After the two ends of the light distribution plate are respectively inserted into the two mounting holes 121, the light distribution plate distributes light to the second light source assembly 40. Because the two ends of the light distribution plate are respectively connected with the two mounting holes 121, no gap exists between the light distribution plate and the first shell 10, so that the light distribution plate is beneficial to more comprehensively distributing light to the second light source assembly 40, the uniformity of light rays of the whole lamp is improved, and the glare problem is better improved.
In addition, the existing light distribution plate is generally provided with a flanging, the lamp housing is correspondingly provided with a flanging, and the flanging of the light distribution plate is matched with the flanging of the lamp housing, so that the light distribution plate is connected with the lamp housing.

Preferably, as shown in fig. 6, the outer surface of the first housing 10 is provided with a mounting groove 17, and the mounting groove 17 is provided at the junction of two adjacent reflecting surfaces 14. The adjacent reflecting surfaces 14 are easy to form grooves at the connection positions, and the grooves are convenient to form the mounting grooves 17, so that the mounting grooves 17 can be used for mounting the power supply assembly 80. The power supply assembly 80 is installed without additionally providing an installation space, thereby being beneficial to reducing the volume of the lamp housing and the height of the lamp housing, and being capable of reducing the requirement of the lamp housing of the embodiment on the height of the installation environment.
