However, it can be understood that the reflecting plate 4 and the condenser lens 5 can also be fixed in other non-detachable ways in the imaging outer cylinder 1 .

Referring to FIG. 2 and FIG. 11 , the spotlight further includes a ventilated rear cover 7 threadedly connected to the lower end of the imaging outer cylinder 1 for heat dissipation. The ventilation rear cover 7 is provided with a plurality of ventilation holes 71 , and the ventilation holes 71 are arranged in a vortex shape. More preferably, in other embodiments, a cooling fan (not shown) may also be installed at the lower end of the heat sink 2 to further enhance the cooling effect.
