[0026] The light-emitting subunit includes a housing 11, an input wire assembly 12, an output wire assembly, a first light source board, and a second light source board. The input wire assembly 12 and the housing 11 are integrally formed into a whole 1 by injection molding. The housing 11 has a groove 121 for installing the output wire assembly 5 on the side away from the input wire assembly 12. A sealing ring 4 is provided between the output wire assembly 5 and the bottom of the groove 121. The output wire assembly 5 has a mounting hole 51 for a bolt 6 to pass through. After the bolt 6 passes through the mounting hole 51, the output wire assembly 5 and the sealing ring 4 are press-fitted together.
