The types of the first housing 12 and the second housing 11 may be set according to actual use requirements, and it is only necessary to ensure that light emitted from the light emitting element 21 disposed in the accommodating cavity can be emitted through at least one of the first housing 12 and the second housing 11. Preferably, the first casing 12 of the present embodiment is a transparent lampshade; the second housing 11 is a heat dissipation case. Further, the light emitting elements 21 are disposed on a side of the light source plate 2 facing the transparent lamp housing.
To help accelerate the flow rate of air flowing through the second housing 11, the present embodiment preferably sets the maximum longitudinal width of the cross section of the lamp housing 1 to be greater than the maximum transverse width. Because the fishing lamp installed on the fishing boat is greatly affected by wind power, the first shell 12 with the arc-shaped outer surface faces to one side of the sea surface, the first shell 12 can cut off fluid acting on the first shell, and because the second flow guide surface 22 is tangent to the first shell 12, the maximum longitudinal width of the cross section of the lamp shell 1 is larger than the maximum transverse width, the cut air can flow through the first shell 12 and the second flow guide surface 22 at an accelerated speed, the surface heat dissipation of the lamp can be accelerated, and the reliability and the service life of the lamp are improved.
