[0011] As a further improvement of this utility model, the inner ring of the double ball bearing is interference-fitted with the shaft body, and the outer ring is tightly connected to the inner wall of the through hole, ensuring smooth rotation of the shaft body and structural stability.

[0012] As a further improvement of this utility model, the arc design of the arc groove is adapted to the lighting angle adjustment range to meet the conventional lighting angle adjustment requirements, such as adjustment within the range of 0-90 degrees.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting a rotation adjustment component, the crank handle drives the rotating shaft to rotate, thereby adjusting the lighting angle of the lamp housing and lighting component. After adjustment, tightening the fastening nut will fix the connecting screw in the arc groove, thereby stabilizing and fixing the lighting angle. The operation is convenient and the fixing effect is good, which solves the problems of inconvenient lighting angle adjustment and easy deviation of the existing lamps.

[0015] 2. In this utility model, by setting the lamp housing as an aluminum alloy housing and opening heat dissipation grooves on the inner side wall of the lamp housing, the heat dissipation area is increased.
