An adjustable hanging element is provided herein for suspended light fixtures which allows for adjustment of a point of contact for suspension both upon initial installation and while installed, without the need for taking the fixture down.

An LED cove light system having a wall piece mounted to a back surface of a cove, the wall piece having a top edge which is at the same height as a top surface of a front wall of the cove. A light fixture component is removably attachable at an angle to the wall piece and carries one or more LEDs positioned to project light from the cove out into an adjacent space of a room.

A light fixture assembly configured to direct light outwardly and downwardly, while precluding the directing of light upwardly. The light fixture assembly comprises a housing, an LED light and a reflector. The LED light includes a mounting surface and a light emitting member. The mounting surface is coupled to the housing, and in particular on an inside surface of the upper side wall, with the light being directed in at least a downward direction. The reflector includes a second portion which is positioned within the inner cavity and below the LED light. The second portion is angled at least at 45° relative to a horizontal axis in an operational configuration. The reflector directs light imparted by the light emitting member in at least one of a downward and an outward direction, while precluding the directing of light imparted by the light emitting member in an upward direction.

An LED cove light system having a wall piece mounted to a back surface of a cove, the wall piece having a top edge which is at the same height as a top surface of a front wall of the cove. A light fixture component is removably attachable at an angle to the wall piece and carries one or more LEDs positioned to project light from the cove out into an adjacent space of a room.

A night light includes a fixed part, a rotatable part and a shaft connecting the rotatable part and the fixed part and allowing the rotatable part to rotate relative to the fixed part. The fixed part includes two pins configured for electrically connecting with an external power socket, and two elastic elements fixed to top ends of the two pins, respectively. The rotatable part includes two concentric annular conductive members exposed at a lower end of the rotatable part. The two elastic elements provide upward elastic support to the two concentric annular conductive members, respectively, such that the elastic elements can constantly contact and press the two concentric annular conductive members when the rotatable part rotates relative to the fixed part.

A universal light mounting box for retrofit is described. The retrofit light mounting box attaches to a junction box and receives electrical power from the junction box cables. The mounting box includes a canopy housing and a camera housing to provide wireless communication of both audio and video capabilities for the area around the junction box while also providing controlled power to a light fixture which is attached to the mounting box. A depending camera housing provides both audio and video signals which can be transmitted from the retrofit canopy housing electronics to a user's device.

A Light device having built-in digital data means is powered by an unlimited power source for a lamp-holder, LED bulb, or light device connected to unlimited power source by prongs or a base that or conductive wires can be inserted into a socket that would otherwise receiving a bulb. The device may take the form of a webcam having auto tracking added one of plurality functions to make different products and functions and retractable prongs that plug directly into a wall outlet or insert into existing lamp base or incorporate conductive wire to make electric connection at least one of built-in camera, storage unit, wireless kits, Bluetooth kits, motion sensor, light device.

A method of installing a light fixture base to a surface is disclosed that employs an elongated tool that engages a mounting screw in rough alignment with an axis of the elongated member. The mounting screw and elongated tool are inserted through a mounting hole in the base and moved upward through thermal insulation in the base. The elongated tool is then manipulated while viewing both a tip end of the mounting screw and a threaded hole in a mounting bracket attached to a junction box so as to attach the mounting screw to the mounting bracket. The elongated tool then serves as a guide while sliding the base upward along the elongated tool so as to rapidly attach the base to a mounting screw in the mounting bracket.

In the soil cultivation system equipped with a solar panel, the space between ridges of a plurality of frame units supporting the solar panels is coupled with a roof member, furthermore, the perimeter surface thereof is integrally covered with a cover unit. In this way, a cultivation house in which the frame units are used as support columns is established. Then, in the solar panels, light transmitting regions are provided, a transmissive member is used as the roof member and thus agricultural plants are cultivated by light passing through the light transmitting regions and the roof member. Furthermore, the cultivation of the agricultural plants is performed in cultivation tanks in which a soil is put, and an appropriate cultivation nutrient solution is supplied through a supply means. In this way, the cultivation environment of the agricultural plants is managed, and thus the agricultural plants can be efficiently cultivated while the burden of an operator is reduced.

A method of mounting an electrically powered device having power receiving contacts and a ground contact on a display comprising a mounting wall comprising: mounting one or more power delivery members on the rear surface of the mounting wall; housing the power receiving and ground contact of an electrically powered device in a housing that prevents electrically conductive manual engagement or contact, inserting the housed power receiving and ground contacts of the electrically powered device through one of the series of apertures in the mounting wall to power and mount the device.
