By adjusting the relative position of the lampshade 4 and the inner cylinder 21, the distance between the illuminant 26 and the transparent mirror 5 is adjusted, thereby controlling the size of the light spot and the irradiation range of the light after passing through the convex lens. When the distance between the illuminant 26 and the transparent mirror 5 becomes farther and farther, the light through the convex lens is focused into a smaller light spot to irradiate a small range. When the distance between the illuminant 26 and the transparent mirror 5 becomes closer and closer, the light through the convex lens gradually diverges to form a floodlight spot, which can illuminate a larger range of areas. In use, the light source can be adjusted quickly and easily according to needs, and the handle 7 installed above the outer shell 1 is convenient for carrying when in use.

[0047] In this embodiment, the light emitting body 26 is specifically a CREE LED lamp.
