The present disclosure discloses a lamp for projecting a nebula and a starry sky comprising a housing, a light source assembly, a laser assembly, a rotating assembly, a control board, a base seat, and a power source port. The light source assembly and the laser assembly are disposed in the housing and penetrate through the housing, and the rotating assembly and the control board are disposed in the housing. The rotating assembly is configured to drive a rotating optical sheet and a diffraction sheet to rotate. The light source assembly comprises a light source board, a light reflecting cup, the rotating optical sheet, and a lens assembly having a frosted surface with an array of protrusions. The light source board, the light reflecting cup, the rotating optical sheet, and the lens assembly are successively disposed along a path in which light rays emitted by the light source board move.

An atmosphere starry sky light for festival entertainment is provided. The constellation unit is configured to switch patterns of twelve constellations and perform projection display on the patterns of the twelve constellations. The starry sky unit is configured to project a starry sky background. The background unit is configured to project patterns of aurora, clouds, and ripples. The planetary unit is configured to switch patterns of a planet, and to project and display a planetary image. The constellation unit, the planetary unit, the starry sky unit and the background unit form a panoramic image of the cosmic starry sky by superimposing and combining.

A projection device for projecting images on a surface of the device includes an outer housing having a front translucent screen, a projection module frame mounted on an inner surface of the outer housing, and a projection roller frame supported by the projection module frame. The projection roller frame includes first and second spaced apart rollers rotatable respectively on two opposite cylindrical ends integrally formed on a lampshade. A cylindrical projection film is held between the first and second rollers. A light source is mounted inside the lampshade so that an image formed on the projection film can be projected on the front translucent screen by the light source. The device further includes a gear mechanism for driving the rollers, a position-limiting mechanism, and a speaker.

A projection structure that occupies a small space and performs dynamic projection includes a first support, a lens assembly, a film portion, a light source, a motor, a control portion, and a second support, wherein the light source, the film portion, and the lens assembly form a projection light path, the film portion being driven by the motor to rotate. The lens assembly includes at least one lens, and the at least one lens is accommodated in the first support, the control portion being configured to control the motor and/or the light source. The second support is configured to support the first support, wherein the first support and second support are respectively configured to form a first space and a second space of the film portion.

A projection toy includes a top housing. A bottom housing is fixedly mounted at a top end of the top housing. A projection mechanism is fixedly mounted between the top housing and the bottom housing. A light-emitting diode (LED) lamp panel is fixedly mounted on one side of the projection mechanism between the top housing and the bottom housing. An end, away from the LED lamp panel, of the projection mechanism is clamped in a limiting enclosure. The limiting enclosure is fixedly mounted at one end of a first cover. A second cover is fixedly connected to the first cover. A decorative cover is fixedly mounted on the second cover. The first cover is fixedly mounted at one end of the top housing and one end of the bottom housing on a side away from the decorative cover.
