BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to a light trolley system and, more particularly, the invention relates to a light trolley system for vertical-plane growing that maximizes the coverage and quality of the light and enables the space to be useable.

2. Description of the Prior Art

High intensity indoor growing environments have unique lighting needs that are not always met by traditional lighting form-factors.

Developing these form factors requires not only new lighting designs, but new designs for mounting lighting and utilizing these lights in a way that maximizes light use efficiencies within the farm.

Vertical-plane growing is no exception, and requires light fixture systems that both hang the lights in a way that maximizes the coverage and quality of the light, but also enables the space to be useable, i.e., allows workers to move lights out of the way when necessary to work on the plants. SUMMARY

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated in FIGS. 1 - 14, the present invention is a light trolley system, indicated generally at 10, for vertical-plane growing in growing towers 12 and the like that maximizes the coverage and quality of the light and enables the space to be useable. The purpose of the light trolley system 10 of the present invention is to allow hanging of bar-type horticultural lights or light trolleys 14 allowing the lights to be water cooled and allowing the lights to be moved out of the way using the light trolley system 10 so that labor can be more efficiently used in the growing area.

The light trolley system 10 of the present invention includes a modular support structure 16 having a plurality of vertical support members 18 and a plurality of horizontal support members 20. Preferably, the modular support structure 16 includes four spaced vertical support members 18 with a horizontal support members 20 connected to the end and extending between adjacent vertical support members 18. Each of the vertical support members 18 and the horizontal support members 20 can include a plurality of support sections 22, either separate or telescoping, that can be added or subtracted from the modular support structure 16 thereby adjusting the vertical and/or horizontal size of the modular support structure 16. A ball detent 24 or other releasable locking means, such as friction, latches, etc., can releasably secure the support sections 22 together that form the vertical support members 18 and the horizontal support members 20 of the support structure 16. In addition, the light trolley system 10 of the present invention includes a pair of C rails 26 suspended and secured between two opposing horizontal support members 20 of the support structure 16. The C rails 26 are preferably surrounded by a C rail bracket 28 to support the C rails from the support structure 16 and to protect the C rails 26 from dirt, debris, moisture, damage, etc.

The light trolley system 10 of the present invention further includes at least one brace 30 mounted to the C rails 26 and includes a connection mechanism 32 allowing the brace 30 to travel along the length of the C rails 26. The brace 30 supports and stabilizes the light trolley 14 and the brace 30 is preferably formed in a square containing structural triangles to provide added rigidity between the light trolleys 14 and while moving the light trolleys 14 along the C rails 26. The square of the brace 30 may be composed of separate parts connected to form one part or as one solid part. It should be noted that the brace 30 is desired, but optional, in that the light trolleys 14 can be connected directly to the C rails 26 without the use of the brace 30.

The connection mechanism 32 of the light trolley system 10 of the present invention can have bearings, wheels, or other features allowing smooth and easy travel of the light trolleys 14 along the C rails 26.

Basically, as mentioned, the brace 30 is designed and constructed to stabilize the light trolleys 14 and inhibit the light trolleys 14 from locking up in the C rails 26 when a user attempts to move the light trolleys 14 along the C rails 26 by grabbing or otherwise manipulating the light trolleys 14 from a far edge of the light trolleys 14. To ensure the braces 30 and the light trolleys 14 of the light trolley system 10 of the present invention are not pushed beyond the C rail 26 limits, at least one stopper 34 are placed at measured locations along each C rail 26. The stoppers 34 include, but are not limited to, a small bump in the rails or a magnet allowing the user to position the braces 30 and the light trolley 14 into operating position for optimal lighting of the grow towers 12, as will be described further below.

As mentioned above, the light trolley system 10 of the present invention preferably includes the light trolley 14 mounted directly or indirectly to each brace 30. The light trolley 14 includes a plurality of bar lights 36 mounted within a light manifold 38. Hanging adjustable pipe clamps 40 connect the light manifold 38 of the light trolley 14 to each brace 30. The light manifold 38 is preferably constructed of rigid tubing having an intake port 42 and output port 44. Each of the intake port 42 and the output port 44 have a flexible tubing connector for joining the rigid pipes of the light manifold 38 of the light trolley 14 to flexible tubing thereby allowing light trolleys 14 to maintain mobility. The flexible tubing allows water to be introduced into light manifold 38 of the light trolley 14 to cool the bar lights 36 and allows mobility of the suspended bar lights 36 and the entire light trolley 14. Thus, the hanging adjustable pipe clamps 40 allow the water cooled bar lights 36 to be hung by their irrigation 38, if desired, as will be described below.

For lights that are not water cooled, the brace 30 of the light trolley system 10 of the present invention can be connected to a platform which supports the light bars 36. Power supplies 46 used to operate the lights may also be mounted to the brace 30 or mounted directly to the modular support structure 16.

Using the light trolley system 10 of the present invention, the bar lights 36 can hang from their frame/body, i.e., the light manifold 38, or by a support platform, or by irrigation connecting the bar lights 36 together in water-cooled systems. In addition, by using light trolleys 14, workers can walk into the growing environment, and push the lighting trolleys 14, out of the way in whichever direction they choose. This allows the growing space to stay open and easy to work in, and allows for tighter aisle widths in order to pack more production into a smaller space without sacrificing access to the racks for workers. The light trolley system 10 is designed to allow coolant to continue flowing through the bar lights regardless of their location relative to the growing racks or towers 12. Movement of light trolleys 14 of the light trolley system 10 of the present invention is initiated by pushing directly on the light trolleys 14, moving the light trolleys 14 by a handle attached to the light trolleys 14, or by a motorized or manual pulley system. The light trolley system 10 of the present invention allows bar-type lights 36, whether water cooled or air cooled, to be hung vertically in a growing environment and effectively moved out of the way. It simplifies the growing environment and human activities in that environment. The light trolley system 10 of the present invention allows a user to hang bar lights 36 in a vertical fashion. This apparatus will allow not only vertical light orientation, but also allow the bar lights 36 to be moved effectively out of the way of greenhouse workers, doing something that no other lighting suspension system allows. In vertical farming markets, as well as high-intensity inter-lighting scenarios, this orientation and setup can be extremely useful to producers, especially as they adopt vertical plane production techniques.

The light trolley system 10 of the present invention is designed to hold two rows of growing towers 12, i.e., the growing plane. The growing towers 12 are placed in the middle of the light trolley system 10 or placed on either side of the light trolley system 10 to take advantage of the double sided lights. The light trolleys 14 can move perpendicular to the growing plane (FIG. 1) and parallel and horizontally with the growing plane (FIG.

12). Typically, the light trolley system 10 for parallel movement of lights, the light trolley system 10 is larger since for the parallel configuration, the lights stay more out of the way on a larger light trolley system 10 that covers multiple growing towers a row.
