Projection device for generating meteor lighting effect and projection lamp for generating meteor lighting effect

A projection lamp for generating a meteor lighting effect, comprising:

• a housing, wherein the housing is provided with a first light-emitting hole;
• a first incoherent light source, wherein the first incoherent light source is arranged in the housing, and the first incoherent light source emits light toward the first light-emitting hole;
• a first optical path plate, wherein the first optical path plate is arranged in the housing, the first optical path plate partially covers an irradiation surface of the first incoherent light source, and at least one strip-shaped light-transmitting hole is formed in the first optical path plate from a central axis of the first optical path plate toward an outer side direction of the first optical path plate;
• a second optical path plate, wherein the second optical path plate is mounted on the housing, the second optical path plate is arranged on a side of the first optical path plate that faces away from the first incoherent light source, at least one strip-shaped light-transmitting area is arranged at a position that is on the second optical path plate and that corresponds to the irradiation surface of the first incoherent light source, and the light-transmitting area is arranged to intersect with a projection of the light-transmitting hole on a horizontal plane;
• and
• a driving assembly, wherein the driving assembly is arranged in the housing, the driving assembly is in driving connection with the first optical path plate to drive the first optical path plate to rotate;
• wherein the second optical path plate is provided with a plurality of light-transmitting areas, and the plurality of light-transmitting areas are arranged non-parallel to each other.
