A dock light apparatus comprises a light fixture and an elongated arm including an axially straight portion coupled to an axially curved portion having a rigid bend. The straight portion is configured to mount to a wall and the curved portion is configured to support the light fixture.

Systems and methods for collapsible lighting fixtures are disclosed. In aspects, a horticultural luminaire 100 has first and second light fixtures 110, 120 coupled in movable relation between storage and deployed positions by a coupling element 130 applying a retarding torque. Coupling element can be coupling shaft 250 providing friction, or friction hinge cartridge 260. In aspects, hinge 130 has ledge surfaces 218, 228 adjacent rotational hinge faces 216, 226 and extending transverse the rotational plane. In aspects, a horticultural luminaire has an articulated cableway extending through hinge 130 coupling light fixtures 110, 120 and guiding a cable entering from the exterior into cable passageways in light fixtures 110, 120, thereby lessening a cable pinch point during rotation and deployment.

A light shaping article includes a solid optic having a cross-sectional profile including an input interface; a convex output surface opposite the input interface; a concave first side surface extending between the input interface and the convex output surface; and a second side surface opposite the concave first side surface extending from between input interface to the convex output surface. The concave first side surface and the convex output surface are configured such that, when the solid optic receives input light having an input angular range in a plane of the cross-sectional profile, the solid optic guides the light to and emits the light from the output surface in an output angular range in the plane. A prevalent propagation direction of output light in the output angular range is tilted toward the second side surface relative to a prevalent propagation direction of input light in the input angular range.

A desk lamp including a base, a bracket, a lamp body, a flexible touch screen, and a control device that controls the desk lamp to work in a working mode including a first mode and a second mode. When the desk lamp is in the first mode, the control device controls the flexible touch screen to sense a first distance touch. When the desk lamp is in the second mode, the control device controls the flexible touch screen to sense a second distance touch. The desk lamp has the first mode and the second mode. The desk lamp may be controlled to work in a corresponding working mode as needed by sensing the first and second distance touches using the flexible touch screen, and by responding to the sensing signal using the control device.

A grow light for stimulating plant growth is presented herein. The grow light includes a plurality of primary light modules with LEDs fixedly mounted to a support assembly and spaced a distance away from a plant canopy, and one or more secondary light modules movably or pivotally mounted to an end of one or more of the primary light modules. A positioning assembly is disposed interconnected light modules for manually or automatically movably disposing the secondary light modules into different angular positions relative to the plant. A height adjustment assembly is also include to movably position the light assembly, such as the plurality of primary light modules or the secondary light modules in a vertical direction. Additional features can be included, such as positioning sensors, environmental sensors, CO2 delivery systems, water cooling systems, ground wire interconnections, and light frequency control.
