Projection lamp

A projection lamp, comprising a head which comprises:

• a first shell assembly, comprising an opaque bottom shell and a transparent mask connected to the opaque bottom shell, the transparent mask comprising a central region and a peripheral region surrounding the central region;
• a projection assembly arranged in the first shell assembly, comprising an optical lens, an optical element, a light source and a driving source for driving the optical element to move, the optical lens comprising a central region and a peripheral region surrounding the central region, the optical element being positioned to direct light from the light source to the optical lens when the light source is powered;
• and
• a light shielding member, at least part of which is disposed between the peripheral region of the transparent mask and the peripheral region of the optical lens, the light shielding member having a first opening in a middle portion thereof so that the central region of the optical lens is aligned with the central region of the transparent mask, wherein the light from the light source only passes through the first opening of the light shielding member to emit out from the transparent mask after passing through the optical lens.
