The present invention is directed to an LED strip light conversion system for converting fluorescent strip light fixtures to LED strip light fixtures. The system includes a set of adjustable installation clip members. Each of the adjustable installation clip members includes an L-shaped slide plate and a clip structure that is slidably couple to a bottom portion of the L-shaped slide plate. The LED strip light conversion system also includes an LED strip light unit. The adjustable installation clip members are used to attach and secure the LED strip light unit to existing strip light housing having a range of widths or dimensions.

A lighting fixture includes a frame, one or more LED light sources to emit radiation, control circuitry to receive AC power and control the one or more LED light sources, and a coolant pipe to carry a fluid coolant. The lighting fixture further includes a tube and end caps that together form an enclosed cavity to contain the frame, the LED light sources, and the control circuitry. In example implementations, the tube does not physically contact the frame, the LED light sources, and the control circuitry. The cavity may further contain air, gas, or vacuum that forms a thermal barrier between the tube and the LED light sources to reduce heat dissipation from the LED light sources to the environment. The tube may further enable the lighting fixture to be rotatably and/or translationally adjustable relative to a support structure after installation in a close proximity grow system.

A light tube with anti-electric shock protection function and capable of being supplied with electricity by electrical ballast and alternate-current power supply in working frequency includes two conductive pin assemblies, a bridge rectifier, an anti-electric shock detection control circuit, a direct-current filtering circuit, a bleeder resistor, a buck-boost constant current module, and a rectifier. The direct-current filtering circuit is connected to the anti-electric shock detection control circuit and the bleeder resistor. The direct-current filtering circuit performs a smoothing procedure to a direct-current pulse voltage signal which is rectified by the bridge rectifier, the direct-current filtering circuit generates a false voltage to the anti-electric shock detection control circuit, and the bleeder resistor reduces the false voltage. The rectifier is connected to the bridge rectifier to receive a rectifier circuit, and the electrical ballast inputs the voltage signal to the bridge rectifier.

Disclosed is a grow light system of any of a variety of modular LED light bars. The light bars may emit light that is heavily-weighted in a red wavelength spectrum, particularly suited for fruiting and flowering growth stages of growing plants, or heavily-weighted in a blue wavelength spectrum, particularly suited for beginning growth stages of growing plants, or in a full wavelength spectrum more closely approximating white light, particularly suited for all cycles of plant life, or any of a variety of other useful light output spectra, or combinations thereof. The light bars may be stand-alone components or combined in a modular fashion. The system may also include a green LED exit sign and/or luminaire emitting light in a limited green wavelength spectrum, providing illumination while not adversely affecting plant growth during dark cycles. The light bars may be suspended from an adjustable rectangular frame.

The reflex lamp housing is of enhanced structural strength and improves the lighting effect.

An x-axis curvable LED strip includes an elongated curved channel having a bottom portion and one or more walls extending therefrom; an elongated lens to secure over a top of the elongated curved channel; and a flexible light strip, having a mounting strip to secure to one of the one or more walls of the elongated curved channel; LED lights attached to the mounting strip by an extension such that the LED lights are positioned within the elongated curved channel along the bottom portion; the LED lights emit light through the elongated lens.

A light stack having an elongate body having a length extending from a proximal end to a distal end of the elongate body. A plurality of light emitting diode (LED) arrays adjustably coupled with the elongate body and arranged along the length thereof and a control module coupled with the plurality of LED arrays, wherein the each of the plurality of LED arrays is operable to pivot, thereby forming an angle relative to the elongate body. The control module configured to individually transition each of the plurality of LED arrays between a light emitting condition and a non-light emitting condition. The plurality of LED arrays configured to be adjustable to pivot on an axis at an angle relative to the elongate body.

An overhead electrical infeed system includes an overhead mount surface, an electrical cord coupled to the overhead mount surface, an electrical outlet assembly coupled to a distal end portion of the cord having a proximal end portion mounted to the overhead mount surface and a distal end portion spaced from the proximal end portion. At least a portion of the weight of the electrical outlet assembly is supported by the electrical cord. A retractor is positioned along the electrical cord and is operable to raise the electrical outlet assembly or to retain the electrical outlet assembly at a selected elevation. An electrical outlet is electrically energized by the electrical cord and is mounted to the electrical outlet assembly, to provide users with access to electrical or data signals.

A hydroponic grow assembly including an assembly base and at least one plant structure removably connectable to the assembly base to form a plant wall for growing plants. The plant structure includes a plurality of plant wells opened to a root chamber and the base includes a bottom structure enclosed by a perimeter wall to form an inner cavity of a reservoir tank to supply water to the root chamber of the plant structure. The bottom structure includes a support feature within the inner cavity of the reservoir tank to support the at least one plant structure in an upright position to form the plant wall of the assembly.
