When the water absorption expansion strip 103 absorbs water and expands, water vapor enters the joint of the water absorption expansion strip 103 and the elastic sealing ring 10, so that the viscosity of the water absorption expansion strip 103 and the elastic sealing ring 10 is weakened, and subsequently, if the water absorption expansion strip 103 needs to be replaced, the water absorption expansion strip 103 can be directly pulled away from the elastic sealing ring 10, and the replaced water absorption expansion strip is adhered to the elastic sealing ring 10 again, so that when the limiting block 72 passes through the inner ring of the elastic sealing ring 10, the water absorption expansion strip 103 is firmly connected with the elastic sealing ring 10, and when the water absorption expansion strip 103 needs to be replaced, the water absorption expansion strip 103 can be conveniently pulled away from the elastic sealing ring 10 for replacement.

Referring to fig. 9, 10 and 11, the through hole 712 is opened at the end of the rotation rod 71 far away from the limit block 72, and a plurality of air vents 713 are opened on the side wall, and the plurality of air vents 713 are arranged along the circumferential direction of the rotation rod 71 at intervals and are all communicated with the through hole 712. The sidewall of the stopper 72 is opened with a connection hole 721, and the heat dissipation chamber 91 is connected to the through hole 712 through the connection hole 721. By utilizing the connecting hole 721 and the through hole 712, the heat dissipation cavity 91 of the flexible heat conduction strip 9 is matched, so that the heat dissipation cavity 91 is communicated with the external environment, the closed ends at the two ends of the flexible heat conduction strip 9 and the elastic sealing ring 10 are assisted, the heat dissipation cavity 91 forms a sealed heat dissipation passage relative to the shell cavity 12, and the heat dissipation efficiency of the lighting device is improved while the sealing performance of the lighting device is considered.

The implementation principle of the embodiment 3 is as follows: rotatory dwang 71, stopper 72 pass through the inner circle of elastic seal ring 10, then separate flexibility heat conduction strip 9 with the bottom of LED lamp plate 3 top from deformation groove 21, leave the clearance between the bottom of messenger LED lamp plate 3 and deformation groove 21 to the fluid that supplies in the heat dissipation chamber 91 passes through. External fluid passes through hole 712 to through connecting hole 721, enter into in the heat dissipation chamber 91, then flow to external environment through connecting hole 721 and through-hole 712 flow direction again, and the external environment is taken away from with the heat of LED lamp plate 3 to this realization is giving consideration to lighting device sealing performance, improves lighting device's radiating efficiency.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
