The utility model discloses a projecting device for generating a light effect of a galactic starry sky, including: a light-emitting assembly including at least one first incoherent light source and at least one first condensing lens, the first condensing lens being arranged on an illuminating surface of the first incoherent light source; a film assembly including a film sheet provided with a galactic starry sky pattern, the film sheet being arranged on the other side of the first condensing lens relative to the first incoherent light source; and an imaging assembly including at least three lenses, the three lenses being an imaging lens, an adjusting lens, and a wide-angle lens arranged sequentially in a projection direction of the film sheet, respectively. The technical solution of the utility model effectively improves practicality of the projecting device by setting a plurality of functional lenses.

A projection lamp and a lamp holder include a housing defining a projection port, a lampshade covered on the projection port of the housing, and a projection lamp assembly. Light is emitted from the projection port. The projection lamp assembly includes at least two light sources and a first corrugated sheet. Patterns are provided on the first corrugated sheet. The at least two light sources are configured to emit the light. The light passes through the first corrugated sheet and the lampshade to emit out. Projection brightness of the at least two light sources is great and the first corrugated sheet is replaceable. A projected image is replaced by replacing a pattern-changing gear in tan inserting groove. Light strips are arranged on an outer wall of the projection lamp to create a visual atmosphere effect.

An integrated-lighting-module may have a driver cap, a heat sink module, a LED light chip, an optical reflector, and a holder/trim. The driver cap may be configured to hold a driver within the driver cap to power the LED light chip. The driver cap may attach to a top of the heat sink module. The heat sink module may be finned at various locations. The holder may attach to the heat sink module with the optical reflector and the LED light chip disposed between elements of the holder and elements of the heat sink module. Trim, such as MR16 sized trim, a lamp, and/or a lens holder, may attach to bottom flanges of the holder. The integrated-lighting-module may be adjusted without interfering with the trim. The holder may be trim in some embodiments.

The present disclosure discloses an intelligent wearing device with LED lamps and relates to the technical field of outdoor wearing. The intelligent wearing device includes a knitted hat body, a fixed leather ring and a main housing, wherein a heat radiation plate is transversely fixed inside the main housing, an aluminum substrate is fixed to the obverse side of the heat radiation plate, white-light LED lamps are fixed to middle positions of the obverse side of the aluminum substrate, and an intelligent electrical control system and a lamplight adjusting apparatus are mounted in the main housing. According to the present disclosure, the irradiation range of lamplight may be adjusted by a lamplight focal length adjusting mechanism, so that the irradiation effect is effectivelyimproved; and the irradiation height of the lamplight may be adjusted by a lamplight height adjusting mechanism.

An illumination device includes a light source unit that emits light, a first optical unit that lets the light enter and changes a divergence angle of the entered light, a second optical unit including an image light formation unit that lets the light with the changed divergence angle enter and emits light including image light having image information, and a drive unit that moves the first optical unit and the second optical unit.

A variable-focus lighting device and a variable-focus lighting system have one light source and are used to adjust the position and focus of light that is emitted, among various positions in an interior space. An installation space on an interior roof is reduced and manufacturing costs are reduced.

A downlight apparatus has a rotatable base, a light module and a front cover. The light is rotatable in a spherical rotating space defined by the rotatable base. There is a stop structure for keeping the light module staying at rotating angle with respect to the rotatable base when there is no external force applying on the light module.

A lighting fixture includes a light source holder, a pair of position adjustors, and an outer shell. The light source holder holds a light source. The position adjustors are arranged to face each other and interpose the light source holder between themselves and supports the light source holder to allow the light source holder to rotate around a first virtual axis defined as a virtual axis passing through the position adjustors. The outer shell has an opening in which the light source holder and the position adjustors are arranged and supports the position adjustors to allow the position adjustors to rotate around a second virtual axis defined by a normal to an opening plane of the opening. The first virtual axis intersects with the second virtual axis and is located either within or behind the opening plane.
