A light with retractable sleeve comprises housing, a retractable sleeve disposed inside the housing, and a light body embedded in a front end of the retractable sleeve and protruding out of the housing; the retractable, sleeve comprising an inner sleeve, an outer sleeve disposed outside the inner sleeve, and a connector; the inner sleeve having a gear rack; the outer sleeve having thereon a button corresponding to the gear rack; the button being attached on the gear rack via a resilient element to prevent the outer sleeve from undesirably moving out of the inner sleeve along the axial direction; the outer sleeve and the inner sleeve can be extended with each other, so that the outer sleeve is extended out of the housing, thereby facilitating the light body installed thereon, the structure is simple and easy to use.

A multi-branch conductive rotary mechanism with low cost includes a main body and a rotating shell configured to axially rotate with respect to the main body. A drive motor and a rotating connector are arranged inside the main body, and the rotating connector is driven by the drive motor to synchronously rotate. The rotating connector is connected to the rotating shell, and the rotating connector is configured to drive the rotating shell to synchronously rotate. The multi-branch conductive rotary mechanism further includes at least one external connector arranged on an outside of the rotating shell, and a projection lamp assembly. The at least one external connector is configured to be connected to external functional components. The projection lamp assembly is arranged on an inside or an outside of the main body.

An attachment system for attachment to a signaling device includes an attachment member. The attachment member is formed of a ring-shape made of an elastic material and includes an annular base and at least one fin. The annular base includes an external peripheral edge and a central orifice defining an internal peripheral edge. The annular base also includes an annular lower face and an annular upper face. The fin projects from the external peripheral edge of the annular base. The attachment member is movable between a rest configuration in which the annular base is planar and extends in a main plane to allow insertion and positioning on the signaling device at a selected position, and a deformed configuration in which the annular base is non-planar in a deformed state in order to be able to match a peripheral area of the signaling device.

The present invention relates to a flower-structured, dynamic, decorative lamp, at least three the sliding arms are hinged at the pivot section of the sliding support through a restricting member in the form of being separated by an angle from each other, and that in the case of simulating the opening of petal structure, the sliding arms can change the angle made with the limiting rest by the movement of the sliding rod connected to the sliding support in the direction of its own axis. One end of the sliding rod is connected to the sleeving section of the sliding support and the other end is connected to a damper device or a power transmission device that drives the sliding rod pass through the center of the limiting rest to move the sliding support.

A light fitting system has a light fitting for recessed mounting of a luminaire in a substrate such as a ceiling, which fitting comprises a luminaire support and a base for receiving the luminaire support and in relation to which base the luminaire support may be manipulated or moved or directed, and a tool for manipulating the luminaire support. The luminaire support and the luminaire support tool are configured for cooperative inter-engagement whereby the tool may be releasably inter-engaged with the luminaire support to enable manipulation of the luminaire support in relation to the base providing the advantage of a readily adaptable or manipulated luminaire support angularly adjustable or removable by means of the luminaire support tool thereby enabling adjustment and/or removal and replacement of a luminaire from a base without dismantling the fitting from the substrate into which it is mounted.

An LED downlight assembly accommodates square and round trims and its components may be removed irrespective of the presence of mudded in round or square mud plates. The assembly also includes a collar that can be fitted to ceiling of varying thicknesses.
