The first driving device may be coupled to the reflective medium, the fixing column may pass through the second through-hole into the reflective medium, and the at least one first incoherent light source may be connected to the fixing column.

Provided are a structured light projector that generates and projects structured light, and an electronic apparatus including the structured light projector. The structured light projector includes an illuminator configured to emit light, a pattern mask configured to form structured light by partially transmitting and partially blocking incident light from the illuminator based on a pattern of the pattern mask, and a lens configured to project the structured light. The illuminator includes a plurality of illumination areas respectively facing a plurality of areas of the pattern mask, wherein intensities of lights respectively emitted by the plurality of illumination areas are different from one other.

A structured light projector includes a light source configured to emit light, a structured light pattern mask configured to receive the light emitted by the light source and including a first region configured to generate a first structured light having a first polarization and a second region configured to generate a second structured light having a second polarization that is different from the first polarization, and a polarization multiplexing deflector configured to deflect the first structured light and the second structured light generated by the structured light pattern mask, to different directions, respectively.

A ceiling fan with a ceiling projection function includes a ceiling fan body and a ceiling fan housing. The ceiling fan body includes a plurality of blades, a motor that drives the blades to rotate, and a hanging rod. The ceiling fan housing is provided with a pattern hole unit and a light-emitting unit. The pattern hole unit has at least one pattern hole. The pattern hole of the pattern hole unit passes through the ceiling fan housing. The light-emitting unit has at least one light-emitting member. When in use, the light-emitting member of the light-emitting unit projects a light beam passing through the pattern hole of the pattern hole unit to project a pattern of the pattern hole of the pattern hole unit outside the ceiling fan housing and above the blades.

A structured light projector includes a light source configured to emit light, a structured light pattern mask configured to receive the light emitted by the light source and including a first region configured to generate a first structured light having a first polarization and a second region configured to generate a second structured light having a second polarization that is different from the first polarization, and a polarization multiplexing deflector configured to deflect the first structured light and the second structured light generated by the structured light pattern mask, to different directions, respectively.

The present disclosure discloses a projection lamp. The projection lamp includes a light-emitting assembly including at least one first non-coherent light source, a light-reflection medium, a first condensing lens, a driving device, a driving gear, and a driven gear. An inner wall surface of the light-reflection medium is formed by mutually connecting a plurality of irregular light reflection surfaces; the first non-coherent light source is arranged in the light-reflection medium; the first condensing lens is arranged above the light-reflection medium; the driving gear is connected to the driving device; and the driven gear is arranged on the light-reflection medium and is engaged with the driving gear to drive the light-reflection medium to rotate. The technical solution of the present disclosure effectively improves the diversity of the light effect of the projection lamp.

The present invention relates to a snowflake projection lamp, including a housing, a concatemer optical lens arranged at the front end of the housing, a main control board and a projection component arranged in the housing, and a rotating shaft component connected to the lower end of the housing, where the front end of the housing is provided with an opening, the inner side of the opening is provided with a first surrounding wall, the concatemer optical lens includes a mounting base and a lens group, a first groove is internally provided with a sealing ring, and the concatemer optical lens is pressed on the first surrounding wall of the housing through the sealing ring; Lamplight of a high-brightness light source component passes through a film driven by a motor component to project multiple dynamic spots with different sizes and snowflake patterns in a designated region.

A projection lamp with a dual projection function, including a base. The base is provided with a first light-emitting element and a first projection film. Emitted light of the first light-emitting element can pass through the first projection film to be projected outward. The base is provided with a slide projection unit, which includes a light-emitting assembly and a second projection film. Emitted light of the light-emitting assembly can pass through the second projection film to be projected outward. The emitted light of the first light-emitting element passes through the first projection film to be projected outward to form a projection pattern corresponding to the first projection film, and at the same time, the emitted light of the light-emitting assembly passes through the second projection film to form the projection of the slide.

A light-and-shadow decoration includes a main decorative object, an omnidirectional rotation mechanism, and an electrical control unit. The main decorative object includes a three-dimensional structure and has one side that is provided with a retaining seat. The omnidirectional rotation mechanism includes a support axle, a rotation base, and a projector. The support axle has two ends each provided with a universal-joint ball. The rotation base and the projector are respectively connected to the two ends of the support axle. The projector has one side on which a lighting cover is mounted. The electrical control unit includes a power supply portion and at least one light-emitting element. Light from the light-emitting element transmits through the lighting cover to project to the outside. As such, the omnidirectional rotation mechanism enables rotation of the light source relative to the main decorative object and the support axle for adjusting a projection direction thereof.
