Apparatus and methods for a hydroponics system with enhanced heat transfer are presented herein. By arranging the flow hydroponics system to have a series flow pattern via tubes and hydroponic pans, heat may be transferred from heat producing elements. The heat producing elements, including light emitting diodes (LEDs), may be thermally attached to the pans. The recycled heat can be transferred to the series circulating water supply for providing nutrient rich minerals at the roots of plants. Additionally, the heat can be transferred via the pans and without the need for costly fans or specialized heat sinks. In this way more space can be availed for the production of plants while recycling energy in the form of transferred heat.

A system for heat and light management for indoor horticulture is described. More particularly, a system including light sources, a light distribution chamber, and circulating water is described.

A lighting device (30) and a method of manufacturing such a lighting device are provided. The lighting device comprises a sheet assembly (7), which comprises a substrate (1) being at least partly light transmissive, a plurality of light sources (5) coupled to the substrate. At least a portion of the sheet assembly (7) is fixed in a rolled-up arrangement so as to form a roll (12), whereby the light sources (5) in the portion of the sheet assembly (7) are arranged to emit light at least partly inwards in the roll and/or at least partly towards at least one end (31) of the roll. The present invention is advantageous in that it provides enhanced lumen density output, which makes the lighting device useful for high brightness applications, such as head lights and fluid purification.

A system, apparatus, and method for thermal regulation in a tiered rack growth system. A contact heat exchange converter is provided to remove thermal energy of a light fixture for the tiered rack growth system. A contact thermal exchange cavity defined in the contact heat exchange converter is dimensioned to cooperatively receive an arcuate thermal sink of the light fixture. A circulation conduit communicates a dense medium coolant to remove thermal energy carried by a thermal mass of the contact heat exchange converter.

An underwater pendant light installation within a wall of a water feature has an installation tube in a niche tube having a facia section at the terminus of the niche tube. One terminus of the niche tube in communication with the water feature and having a water inlet coupled to a water gap section. An at least one underwater pendant or accent light having a housing, a lens body, an electronics section, an at least one heat sink, and one or more LEDs is mounted within the niche tube. The underwater pendant or accent light being coupled in a watertight fashion to a power source through the watertight coupling and being contained within the niche tube such that the water gap section surrounds at least in part the housing and permits water from the water feature to circulate in contact the housing but not penetrate into the watertight electrical connection.

A light trolley system for vertical-plane growing that maximizes the coverage area, quality of light, and useable growing area is provided. The light trolley system comprises a support structure and a first C rail secured to the support structure. The first C rail has a first end and a second end. A first brace is mounted to the first C rail and a first light trolley secured to the first brace. The first light trolley has at least one bar light mounted within a light manifold. The first brace supports and stabilizes the first light trolley. The combined first brace and first light trolley is moveable along the first C rail between the first end and the second end of the first C rail allowing the first light trolley to be moved to various locations increasing labor efficiency in the growing area.
