The present disclosure is directed to projection devices that can project patterned light of different colors. In one implementation, the projection device can include a housing, within which reside multiple components. These components can include light emitting diodes (LEDs), a parabolic mirror reflector, a sinusoidal lenticular diffuser, and multiple spatial filters. The multiple LEDs can be provided in at least two distinct colors. The parabolic mirror reflector can be arranged to collimate light received from the multiple LEDs. The sinusoidal lenticular diffuser can be positioned at an output of the parabolic mirror reflector and arranged to diffuse the collimated light. The spatial filters can be arranged to diffuse the diffused and collimated light received from the sinusoidal lenticular diffuser. An imaging lens can be coupled to the housing and arranged to magnify the diffused light received from the spatial filters and display a cloud-like effect on a first surface.

An illumination device includes a plurality of light sources arranged in at least a first group of light sources having one or more light sources and a second group of light sources having one or more light sources and further includes one or more light collectors, each being arranged for collecting light from one or more light sources from the first group of light sources and for converting the collected light into one or more light beams. The first and second groups of light sources are each individually controllable. The first and second groups of light sources are both arranged for emitting light from a space on one side of the one or more light collectors. The illumination device is arranged so that light emitted from the second group of light sources through the one or more light collectors defines a pattern comprising one or more elongated elements.

The invention discloses a new type of music starry sky projection lamp, comprising a casing, a projection component provided in the casing, and a thumb wheel component; the projection component comprises a swinging transparent water pattern cover, a swinging arm, a fixing plate, a projection lamp bead, and a motor; the thumb wheel component comprises a thumb wheel device body, a thumb wheel lamp bead, a thumb wheel pattern plate, a plano-convex condenser, a biconvex lens, and a pattern plate positioning device. The invention is provided with a swinging transparent water pattern cover, pattern pieces, and a variety of pattern imaging transparent covers, so that the irradiated light is imaged as water pattern or cloud and fog, the irradiated light is imaged into a beautiful pattern, and the projected pattern can be switched by rotating the thumb wheel pattern plate, and can simulate different and various starry sky projection effects.

The present invention relates to a lighting device for creating a light beam comprising a light source and an optical element positioned along an optical axis (80) between said light source and an outlet for said light beam wherein said optical element comprises an at least partially transparent or translucent effects wheel (1), said effects wheel (1) being movable between a first active position in which the effects wheel (1) is positioned along said optical axis (80) and a second inactive position, in which the effects wheel (1) is positioned outside said optical axis (80), and actuation means suitable for moving the effects wheel (1) in a back-and-forth movement between its first active position and its second inactive position.

A flat-type effect module includes a first flat motor and an effect wheel assembly. The first flat motor has a first stator to generate a magnetic field when energized, and a first rotor arranged outside the first stator in a sleeving mode. The effect wheel assembly is fixed to the first rotor, and the effect wheel assembly includes a wheel body for generating a light effect which is provided with effect areas for intercepting a light beam to change the color and/or shape thereof. According to the present invention, no rotating shaft, such as the traditional rotating shaft motor has, exists on the first flat motor, the effect wheel assembly in the present invention is directly fixed to the first rotor, so that the height of the rotating shaft can be reduced and more effect elements can be arranged.

A decorative water lamp with an aroma diffuser structure includes: a water lamp body, having a transparent, three-dimensional shape and being an enclosed space, where the enclosed space is filled with a flowable liquid; a base, connected to and disposed at a bottom of the water lamp body, where an electronic control unit is disposed inside the base; and an incense holder, connected to the base and used for placing an incense body. In the present invention, the incense holder is disposed on one side of the base, to avoid occupying internal space of the base, to make the internal structure of the base simple and proper, and facilitate the deployment of the electronic control unit, a light-emitting component, a magnetic rotating shaft, and a power member.
