Assemblies, systems and methods for balanced suspension of luminaires are provided. In some embodiments a luminaire mounting and suspension assembly is provided comprising a mounting unit and a plurality of suspension units. Each suspension unit comprises a housing coupled to the mounting unit and a yoke pivotally coupled to the housing at a pivot point. The yoke comprises a pair of cable grippers, each cable gripper positioned on opposing sides of the pivot point and configured to grip a suspension cable for suspending a luminaire, wherein an axis of the pivot point is perpendicular to axes of the suspension cables and whereby free rotation of the yoke about the pivot point evenly balances tension between the suspension cables. In some embodiments a luminaire system is provided comprising a mounting and suspension assembly and a luminaire suspended by the assembly. In some embodiments a method of suspending a luminaire is provided comprising providing and suspending a luminaire system and employing the system to evenly balance tension between pairs of suspension cables.

A plant growing lamp includes a lighting unit and a hanging unit. The lighting unit includes a control box and a sliding part, and the hanging unit includes connection lines and a rope ratchets. Cables such as the rope ratchets and the connection lines can be roughly pulled straightly and fully by weight of the lighting unit. The rope ratchets can be pulled to adjust a distance between the lighting unit and the hanger, so as to change an interval between a lamp of the lighting unit and the plants under the lighting unit, thereby appropriately adjusting light intensity for plant growth to prevent from burning the plants.

A fixing mechanism comprises a casing, a plurality of clamping members, and a biasing member respectively configured in the casing. The casing includes an inner surface and surrounds an accommodating space, and the accommodating space has a large-diameter end and a small-diameter end. The plurality of clamping members are configured in the accommodating space, and each clamping member has an outer surface facing the inner surface. A cross section of the outer surface along the axial direction is arc-shaped and the outer surface of the clamping member contacts with the inner surface of the casing partially. The clamping members can be pushed toward the large-diameter end of the accommodating space to separate the clamping members from each other, so that the wire can move between the clamping members. The biasing member is disposed in the accommodating space and located on one side of the large-diameter end. The biasing member can push the clamping members toward the small-diameter end of the accommodating space to make the clamping members close to each other to clamp the wire. Therefore, the contact area and friction force between the clamping members and the inner surface of the casing can be reduced, and the convenience of the operation can be improved. The invention also provides a lamp using the fixing mechanism.
