The fixtures may be independently addressable. The fixtures may be magnetically supported by a fixture support. A brace may join two or more fixture supports without reducing space available to support fixtures. The brace may join a fixture support to a fixture support accessory. An accessory may include a variable-angle junction. The fixture may include articulating joints for controlling the direction of a beam. The fixture may include a lens having an electrically controllable beam spread angle. The fixture may be stowable in the fixture support. The fixture may be slidable along a cord to adjust a height of the fixture. The fixture may include an extendable ring. The system may coordinate motions of the fixtures to follow a target. The fixture may include an elongated board. The elongated board may include a non-polar power socket.

The (LED or-and Laser) light source for bulb or light device such as garden light that has at least one of or more than one optics-lens, and light device has one top cover having shape of flat or ½ ball, ⅔ ball, sphere, dome shape for top cover. Foe laser light source incorporate with flat top protective lens and laser film or grating film to enlarge or created plurality of image, lighted patterns. For LED light source can has project assembly which is a built-in or add-on or assembled inside of said light device. Further can incorporated flexible bendable arms to change position, direction, orientation of (LED or-and Laser) light beam. The said Light device also can offer near-by and far-away illumination, or-and lighted image, pattern projection with desired light effects by rotating optic-lens or LED(s). It also can get desired effects while LED(s) controlled by IC or circuitry making LED(s) for color changing or on-off on desired time, duration, cycles. The light device further can have more than one function selected from USB charger, power failure, RF remote control, Infra-red controller, blue-tooth, wifi, internet, App software, motion sensor and wireless with multiple-way communication. Also, light device may have rechargeable circuit, batteries or rechargeable battery, USB ports for the (LED or-and Laser)-bulb be charged or supply other device current.

Provided is a projection device and projection system that includes a first light source which emits a first light beam, a diffraction part on which first predetermined pattern is provided, and the diffraction part diffracts at least a part of the first light beam emitted from the first light source to form first pattern corresponding to the first predetermined pattern, and a reflection part on which one or more second predetermined patterns are provided, the reflection part reflects a second light beam incident thereon to form second pattern corresponding to the one or more second predetermined patterns, and one of the first pattern and the second pattern forms projection pattern or both of the first pattern and the second pattern are superposed to form projection pattern.

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 interference lens and a projection ambient lamp are provided. The interference lens includes: an interference sheet with a first surface and a second surface opposite to the first surface, the first surface being a rough surface; and a reflective film provided at the interference sheet; wherein light is reflected by the reflective film to form an interference pattern. The projection ambient lamp includes the foregoing interference lens, a light source and a focusing lens; light emitted from the light source passes through the interference lens and is reflected by the reflective film to form an interference pattern, which is focused by the focusing lens and projected on a medium. The present disclosure realizes simplification of the structure by providing a reflective film at the interference lens, hence utilization of light energy is higher, power consumption is lower, manufacturing cost is lower, and projection effect is better.
