Preferably, it is contacted for face between the driving power and the fan, between the fan and the heat-dissipating aluminium plate It is contacted for face.

Preferably, the positioning hook and card slot for preventing relatively rotating are additionally provided between the rotation outer shroud and the shell.

The utility model advantageous effect：

1, focal length can be adjusted, and the intensity and angle of light are adjusted with this so that the extensive angle of light can be at 10 °~100 ° Between change, using flexible；

2, compact-sized, lamp body is smaller；

3, structure installation is reasonable, and internal parts all use screw positioning to fix, and do not shake, and is face between parts Contact, firm stable after installation；

4, good heat dissipation extends the service life of lamps and lanterns.
