[0027] An annular dial 5 is provided on the outer side of both ends of the bracket 1, and an annularly distributed scale protrusion 6 representing the angle value is provided on the outer side of the dial 5. A pointer 20 (concave or convex) pointing to the dial 5 is provided on the outer shell. The pointer 20 is in the shape of an arrow and points to the center of the dial 5, indicating the rotation angle of the outer shell, that is, the irradiation angle of the floodlight. A fastener 7 is provided in the dial 5, and the fastener 7 passes through the bracket 1 and is connected to the outer shell. The fastener 7 is a hexagon socket screw.
[0028] The inner side of the scale plate 5 is provided with a positioning protrusion 8 embedded in the bracket 1, and the positioning protrusion 8 is used to prevent the scale plate 5 from rotating with the rotation of the housing.
[0029] Three mounting holes 9 are provided on the bottom plate of the bracket 1 .
[0030] The housing includes a rear cover 10 and a front cover 11. The front side of the rear cover 10 is open. The driver 4 is fixed in the rear cover 10. The front cover 11 is tubular.
