Abstract: 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.

Abstract: Disclosed are a light emitting assembly and a light emitting device. The light emitting device includes a first light emitting element, a first light transmission portion and a driving portion, The first light emitting element emits a first light beam. The driving portion can drive the first light emitting element or the first light transmission portion, such that a position relationship between the first light emitting element and the first light transmission portion is switchable between a first state and a second state. In the first state, the first light beam passing through the first light transmission portion presents a first pattern; in the second state, the first light beam passing through the first light transmission portion presents a second pattern which is different from the first pattern.
