Disclosed is an automatically adjustable shadowless operating lamp. The automatically adjustable shadowless operating lamp comprises a telescopic support rod. The telescopic support rod is rotatably connected with a first lighting assembly and a second lighting assembly with a same structure, the second lighting assembly is positioned above the first lighting assembly, and the second lighting assembly moves independently with the first lighting assembly; the first lighting assembly comprises a first adjusting part, the first adjusting part is rotationally connected with the telescopic support rod, and is hinged with an adjusting rod through an adjusting piece, a tail end of the adjusting rod is fixedly connected with a second adjusting part, and the adjusting rod is hinged with an operating lamp through the second adjusting part.

A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adj acent a bottom thereof. The light source may be a light-emitting diode.

A support system for a display device includes a first arm configured to extend from a support surface. A second arm is rotatably connected to the first arm. The second arm has a range of movement relative to the first arm. A tilt head is rotatably connected to the second arm and configured to connect to a display. A first biasing member is positioned in the second arm and configured to provide a first counterbalancing force to the second arm to offset a load of the display. A second biasing member is positioned in the second arm and configured to provide a second counterbalancing force to the second arm to offset the load of the display. A lockout mechanism is configured to disengage the second biasing member and eliminate the second counterbalancing through at least a portion of the range of motion.

A sweeping illumination system illuminates an aquarium with organisms requiring simulated sunlight for survival. The illumination system includes a downward-facing light housing for illuminating a top surface of the aquarium. A support arm is coupled to the light housing and enables the light housing to sweep a pattern across the top surface of the aquarium. The sweep pattern can be semi-circular or semi-elliptical along a plane parallel to the top surface of the aquarium.

A lighting device includes a light permeable body which has an aperture through which light enters the body. A light source is moveable relative to the body to enable the lighting device to adopt selectively one of a first configuration and a second configuration. In the first configuration, the light source is positioned over the aperture so that light emitted by the light source passes through the body before illuminating the room. In the second configuration, the light source is spaced laterally from the aperture so that the room is illuminated directly by light emitted from the light source.

The present invention provides an attachment device for an aircraft landing guidance flashing light and an aircraft landing guidance flashing device that do not require adjustment of the angle of the flashing light at the time of attaching an aircraft landing guidance flashing light to the attachment device for an aircraft landing guidance flashing light. An attachment device for an aircraft landing guidance flashing light includes a pair of attachment arms 11; and a light emitting portion fixing plate 12. The light emitting portion fixing plate 12 detachably fixes an aircraft landing guidance flashing light. The light emitting portion fixing plate 12 is supported by the pair of attachment arms 11 such that an angle of the aircraft landing guidance flashing light is at a predetermined angle in a state where the aircraft landing guidance flashing light is fixed to the light emitting portion fixing plate.
