A lighting system has at least one luminaire having a connection portion, and has a fastening device, with a housing; an electrical contact-making connection, which can be detachably inserted into a supply connection of the luminaire, which supply connection is formed in the connection portion; at least one retaining pin, which has a securing portion, wherein the retaining pin, in a fitted state of the fastening device, extends through a slot formed in the connection portion of the luminaire, and the securing portion of the retaining pin is engaged behind a region of the connection portion that defines the slot; and a fastening portion for fastening a retaining cord and/or for connecting the terminals of an electrical supply cable.

An illumination device with a projector includes a base, a shade having a side-surface shade surrounding an outer circumferential side of the base, an upper-surface shade disposed above the base, and a lower-surface shade disposed below the base, a projector which is installed on the base, and projects image light toward the side-surface shade, and an illumination unit for illuminating the upper-surface shade and the lower-surface shade from inside the shade. The side-surface shade is provided with a mirror surface part for reflecting light which shines on the side-surface shade from the outside. The mirror surface part is provided with an image light transmission part which the image light enters. The image light transmission part is a semi-transmissive mirror. Therefore, the image light can be projected via the semi-transmissive mirror, but a projection opening of the projector is not seen from the outside.

The present invention relates to lighting fixtures which are mounted into architectural finished surfaces such as ceilings, walls and floors, and is applicable to new installations as well as the renovation of existing surface-mounted fixtures. One embodiment relates to a modular lighting device for retro-fitting to an existing lamp housing which is flush mounted or countersunk into an opening of a ceiling or interior surface of a building, the modular lighting device comprising a lamp-fitting configured for receiving a light source and configured for attachment to the existing lamp housing, and reflector for reflecting and/or modifying light from the light source, the reflector comprising a narrow top section configured for attachment to said lamp-fitting, and a wider bottom section for covering said opening.

The invention discloses a rotatable lamp hanger, including a fixed seat and a rotatable seat rotatably connected to the fixed seat, wherein a lamp is disposed on the rotatable seat, and the fixed seat or the rotatable seat is provided with a mounting cavity, in which a drive unit is disposed; and further including a power supply that supplies power to the drive unit and the lamp, wherein when the drive unit works, the lamp is rotated under the drive of the rotatable seat that is driven by the drive unit. In this way, with the design of the rotatable lamp hanger, the technical problem of low ornamental value of a ceiling lamp at rest in the prior art is solved.

The present disclosure discloses a lighting lamp including a casing, a heat dissipating plate, heat dissipating fins, a light source plate, a power supply and a light transmitting member. The heat dissipating plate is spaced from the casing to form an annular passage. The heat dissipating fins are spaced along a circumference of a back side of the heat dissipating plate. A portion of each heat dissipating fin is located within the annular passage. The light source plate and the light transmitting member are located on a front side of the heat dissipating plate in sequence. The power supply is located above the back side of the heat dissipating plate. Heat generated by the light source plate and the power supply is conducted to the annular passage and is then carried away by air flow in the annular passage. The lighting lamp has high structural strength and high heat dissipation efficiency.

An insulated electric cord (102) comprises an elongate covering arrangement (12) and at least two elongate electrical conductors (14, 16) held within the covering arrangement (12). The insulated electric cord (102) further comprises an elongate load bearing member (20) held within the covering arrangement (12). The insulated electric cord (102) further comprises an elongate flexible cutting member (22) held within the covering arrangement (12). The elongate electrical conductors (14, 16), the elongate load bearing member (20), and the elongate flexible cutting member (22) extend longitudinally through the covering arrangement (12). The elongate flexible cutting member (22) extends through the covering arrangement (12) adjacent the elongate load bearing member (20). The cutting member (22) is capable of cutting the covering arrangement (12), thereby allowing a portion of the load bearing member (20) to be extracted from the covering arrangement (12).

The invention relates to a lighting assembly (1), comprising an extendible mast (2) constructed and arranged so as to be configurable between a coiled form and an extended form, wherein when extended the mast is resiliently biased in the form of an elongate tube having a slit along its length and wherein when coiled the mast is wound about an axis extending transversely to the longitudinal extent of the mast; and, a lighting element (6) supported by the mast and extending along at least a portion of the mast.
