the circuit of the driving module 3 passes through the lamp holder 2 and is connected with the light source device 12.

The working principle is as follows: when the irradiation position is adjusted, the driving module 3 drives the light source device 12 to emit light, then the heat dissipation cylinder 11 of the lamp body 1 is swung to make the roughly specified position of the light irradiation, then the face cover 132 of the end cover 13 is rotated, the face cover 132 drives the first lens 131 to rotate, and the angle of the light emitted by the light source device 12 entering the first lens 131 for refraction is changed due to the rotation of the first lens 131, so the angle of the light emitted from the light outlet of the heat dissipation cylinder 11 is changed accordingly. Thus, the operator can adjust the light emitted from the lamp body 1 to a predetermined position only by rotating the face cover 132.

From the above description, the beneficial effects of the present invention are: the surface cover 132 is rotatably installed at the light outlet of the heat radiating cylinder 11, and a first lens 131 for refracting the light emitted from the light source device 12 is additionally provided in the surface cover 132. By rotating the surface cover 132, the surface cover 132 drives the first lens 131 to rotate, so that the light emitting angle of the first lens 131 can be adjusted, and the irradiation position can be adjusted in a small scale.

Referring to fig. 3, further, a groove 1321 is disposed on an inner wall of the surface cover 132, and a protrusion 1311 matched with the groove 1321 is disposed on an edge of the first lens 131.

As can be seen from the above description, the first lens 131 can drive the first lens 131 to rotate more smoothly when the front cover 132 is rotated by placing the protrusion 1311 in the recess 1321.

Meanwhile, the light source device 12 can shield the clamping groove 111 after being installed in the heat dissipation cylinder 11, and the clamping groove 111 is a groove formed along the circumferential direction of the inner wall of the heat dissipation cylinder 11, so that the clamp 1322 can be directly inserted into the light outlet of the heat dissipation cylinder 11 to be clamped with the clamping groove 111 when the end cover 13 is assembled, and a clamping point does not need to be found.

Referring to fig. 5, the light source device 12 further includes a heat dissipation plate 121, a COB light source 122, a COB holder 123, and a second lens 124;
