An optical system for assisting image positioning. The system comprises a light source (1), and further comprises a dot pattern or an interface beam-splitting pattern which is arranged on a light-emergent light path of the light source (1) and generates an interface beam-splitting projection light ray for indicating a text or an image after being projected by emergent light of the light source (1). By means of a combination of a light source (1) and a dot pattern or an interface beam-splitting pattern, a word line, a cross line, or the other patterns which can generate a beam-splitting interface can be projected. Furthermore, by virtue of a DOE moulding lens, of which an emergent face is a spherical face or an aspherical face, a specific linear light beam or the other patterns which can generate the beam-splitting interface are generated.

The disclosure discloses a lamp and a lamp assembly. The lamp has a splicing structure and a connecting side, the splicing structure is arranged on the connecting side, the splicing structure includes a first clamping groove and a second clamping groove extending in a same direction, and a notch of the first clamping groove and a notch of the second clamping groove face in opposite directions. Two lamps can be spliced through a lamp connecting module to form a lamp assembly. The lamp connecting module includes a first lamp connector and a second lamp connector, each first lamp connector can be clamped with two first clamping grooves of the two lamps at the same time, each second lamp connector can be clamped with two second clamping grooves of the two lamps at the same time, and the first lamp connector is detachably fixed with the second lamp connector.

A ceiling structure includes a suspended framework having a plurality of main runners and a plurality of cross runners interconnected to define an array of tile receiving openings, each of the plurality of main runners and the plurality of cross runners including a tile mating surface facing downward to define a mounting frame at each respective tile receiving opening, and a plurality of ceiling tiles positioned within the array of tile receiving openings, each of the plurality of ceiling tiles having a main body. The main body of the ceiling tile includes a base having a periphery, a plurality of magnets positioned at the periphery and sized and shaped to magnetically couple the ceiling tile within a respective one of the tile receiving openings, and a plurality of baffles coupled to the base, each baffle being spaced apart from the other. Related methods, systems, and ceiling tiles are also provided.

A decoration is disclosed, which includes: a light source emitting light in at least two directions; a transmission member having an eyeball pattern; and a projection member; the light emitted by the light source in at least two directions passes through the transmission member, and projects the eyeball pattern onto at least two positions on the projection member. Another disclosed decoration includes: two sets of light sources, each set of light sources emitting light in at least two directions; two transmission members, each transmission member having an eyeball pattern; and two projection members; the light emitted by each set of the light sources in at least two directions passes through the transmission member, and projects the eyeball pattern onto at least two positions on the projection member. The decoration has simple structure and diverse functions, and produces a visual effect of moving eyeballs by means of projection for decoration applications.

Embodiments of the present invention relate to a lighting apparatus capable of providing three-dimensional effects at the same time as the surface emission of light sources by using a half-mirror member for reflecting and transmitting parts of light. In particular, by adopting the half-mirror member for transmitting a part of and reflecting another part of light emitted from a surface-emitting light source module, the present invention allows the implementation of a mirror-like image when the light is off, and allows the implementation of a light image providing various three-dimensional effects when the light is on.
