The number of the light emitting units 21 may be set according to the light brightness required by the inverter device 100. In some embodiments, the light emitting unit 21 may be a lamp bead electrically connected to the circuit board 20. In this embodiment, three lamp beads are taken as an example.

The second direction Y is perpendicular to the first direction X, and the first to third portions 31 to 33 are disposed along the second direction Y.

Referring to fig. 4 and 6, the sealing member 40 is disposed around the periphery of the light emitting unit 21 and between the first portion 31 and the circuit board 20, and both the first portion 31 and the circuit board 20 are abutted against the sealing member 40. The abutment means that the two components are in contact with each other and there is an abutment force between the two components, that is, there is an abutment force between the seal 40 and the first portion 31, and there is an abutment force between the seal 40 and the circuit board 20.
