Alternatively, referring to fig. 1, fig. 11 and fig. 12, the number of the light bar assemblies 3 may be 2, 3, 4 or 5. Optionally, when the number of the light bar assemblies 3 is odd, the middle of the light bar assembly 3 in the middle may be connected to the bottom plate of the power box 1 by screws, so as to enhance the structural strength of the lamp.

Alternatively, the end frame 2 may be formed by bending a coated plate or a powder spraying plate, the end cover 5 may also be formed by bending a coated plate or a powder spraying plate, the box body 11 may be formed by bending a coated plate or a powder spraying plate, and the cover body 12 may be formed by bending a coated plate or a powder spraying plate. Therefore, the appearance quality of the lamp can be guaranteed, and yellowing or rusting can be avoided.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
