A cove lighting system includes a plurality of cove extrusions and a plurality of mounting brackets. Each cove extrusion is a single extrusion defining a cove channel and mounting features. The mounting brackets are attached to the wall and the cove extrusions are hung from the mounting brackets with the mounting features. The cove extrusions are hung immediately adjacent to each other to define a continuous cove channel to receive one or more power boxes, and one or more luminaires.

The present invention may comprise a corner mounted bracket for an indirect lighting fixture, mounted flush against vertical walls in a building. The bracket may engage a mounting bracket along an edge. The bracket may have a transverse cross-section in a trapezoidal shape. The bracket may be attached to a vertical wall with screw fasteners. An engagement edge of the bracket may interface with a hook or other structure to engage with a structure to be hung, suspended, or otherwise supported. The bracket may be used in conjunction with a lighting fixture, shelving, or other structures for hanging or supporting securely on vertical walls.

An intermediate connector is provided for coupling to a set of illuminating modules. The intermediate connector has a set of connector arms, wherein each arm has an end that projects over a length from a body of the intermediate connector; a shape to fit into an opening of a corresponding illuminating module to provide, when the arm is seated in the illuminating module, both an electrical connection and a mechanical connection to the corresponding illuminating module; and an external wall with a taper along the length, wherein the end has a cross sectional area, including an areal quantity attributable to thickness of the external wall, that is smaller than a cross sectional area of the opening of the corresponding illuminating module.

A rapid and simple LED display light box includes a base, a support rod and a top supporting element. One end of the support rod can be fixed to the base while the other end thereof is connected to the top supporting element. An LED light bar can be arranged on the base and/or the top supporting element. The LED light bar can be lightened by a storage battery system under the places without power facilities. The light source with the LED light bar supports multiple mounting modes and can meet requirements of various brightness. The structure is firm, assembly is rapid, and collection is simple.

The present invention discloses an optical device (100) and a lighting device for illuminating two intersecting surfaces (S1, S2). The optical device (100) comprises a first light guiding structure (120) for redirecting light from a light source (200) into a first direction and a second light guiding structure (130) for redirecting light from the light source (200) into a second direction different from the first direction, wherein the optical device (100) is arranged to prevent light from the light source (200) from being redirected in a direction between the first and second directions. By positioning the lighting device (100) at the intersection of two surfaces (S1, S2) such as can be found in a step, or at a corner of a wall, or at a corner inside a closet, or on the intersection area of ceilings, the two intersecting surfaces can be illuminated at the same time with comfortable light distribution, using a simple structure that can be easily installed.

A corner lamp includes a lamp base, a light source module set on the lamp base, a first optical element set above the light source module, and an interconnection interface, the lamp base includes at least one corner section, the light source module is set on the outer wall of the corner section and extends along the corner direction; the present invention also discloses an interconnection lighting system; the corner lamp and interconnection lighting system of the present invention, the corner lamp itself can emit light, solving the problem of dark areas in the corner interconnection in the prior art.
