As shown in fig. 1 and 2, the lighting fixture of the present application includes a support column 1, a light source module 4 respectively disposed on the support column 1, and a cover 6 covering the outside of the light source module 4. The support column 1 includes a top end 11, a bottom end 12, and a side wall 13 between the top and bottom ends 11, 12. The light source module 4 is disposed outside the side wall 13, the light source module 4 includes a substrate 41 and a plurality of rows of light sources 42 disposed on the substrate 41, the plurality of rows of light sources 42 are disposed along the circumference of the supporting column 1, and each row of light sources 42 extends along the direction from the top end 11 to the bottom end 12 of the supporting column 1 to form side light emission facing the mask 6. As shown in fig. 10, the maximum light exit surface 422 of each row of light sources 42 on the face mask 6 at least intersects with the projection of the center line 421 of the adjacent row of light sources 42 on the face mask 6.

Through the arrangement of the mode, the lighting lamp can form uniform side light emission as required, the light-emitting pattern of the lighting lamp is increased, and therefore the use requirement can be better met.

To achieve the above objects, the components of the lighting fixture can be arranged in various ways, and the following describes the structure of each component in detail by taking specific embodiments as examples.

The light source module 4 can be disposed in various ways, in a first example, as shown in fig. 5-7, the substrate 41 is substantially planar, and after the substrate 41 is mounted on the supporting column 1, the substrate 41 extends along the direction from the top end 11 to the bottom end 12 of the supporting column 1. The length of the substrate 41 may be slightly smaller than that of the support column 1, and after the substrate 41 is mounted on the support column 1, the top end of the substrate 41 is flush with the top end 11 of the support column 1, and the bottom end of the substrate 41 is offset from the bottom end 12 of the support column 1, so that the bottom of the support column 1 reserves the mounting space of the base 8.
