Patent attributes
A projection lamp is provided, which includes a first shell assembly, a projection assembly and a light shielding member. The first shell assembly includes a transparent mask. The projection assembly includes an optical lens, an optical element, a light source and a driving source for driving the optical element to move. The optical element is positioned to direct light from the light source to the optical lens when the light source is powered. At least part of the light shielding member is disposed between the peripheral region of the transparent mask and the peripheral region of the optical lens. The light shielding member has a first opening, and 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.
