A device and method for altering biochrome ratios in plant leaves is provided. The device and method generally include a light source; and means of directing the light source to deliver an altering spectrum to a group of cells. The altering spectrum alters the biochrome content of a group of cells to produce a contrasting color that creates a desired pattern on a leaf. The device may include a first light source that emits a main growth spectrum, a second light source that emits an altering spectrum; and means of directing the first and second light source to a group of cells, wherein the altering spectrum alters the biochrome content of a group of cells to create a desired pattern on a leaf. Methods of altering the biochrome ratio in a group of cells on a leaf generally involve aligning a surface of a leaf with a light source, activating the light source to produce an altering spectrum, and directing the altering spectrum towards the leaf to create a pattern, wherein cells of the leaf exposed to the altering spectrum exhibit a desired pattern.

The present disclosure provides advantageous lighting systems that can be installed on parallel rows of horizontal supports. The lighting systems can be configured to have a single electrical feedthrough on one end of the lamp that can also act as a mating feature between the lamp and supports. More particularly, the present disclosure provides improved lighting systems that are fixtureless, waterproof, customizable, and easy to install/remove.

A split funnel is provided that includes a top opening that has a first closed inner perimeter and a bottom opening distal from the top opening. The split funnel includes first and second portions that are linked by a bearing structure. The split funnel can be opened and closed along two seams which run from a top opening of the funnel to a bottom opening of the funnel. Methods of using the funnel are also provided.

A growing system is provided that includes a rotomolded chassis that defines (i) an 'interior' where plants are/may be located, and (ii) an 'exterior' that at least partially defines a perimeter around the interior. The chassis generally includes stacking elements which allow one chassis to be stacked one upon the other. The disclosed growing system also generally includes (i) means for delivering liquid into the chassis, (ii) means for draining liquid from the chassis, and (iii) means for supporting plants that is conducive to their growing within the chassis.

Disclosed is an LED lamp system designed to fit into a fluorescent lamp fixture and to utilize a fluorescent lamp power supply contained in the fixture and receiving power from AC mains. The LED lamp system includes an LED driver which comprises a power factor corrected driver circuit for achieving a power factor of at least about 0.8. The LED driver further comprises a current control circuit, responsive to the presence of a three-wire magnetic ballast in the fluorescent lamp power supply, for increasing the LED operating current above the nominal rated LED operating current and to a level sufficient to achieve power factor of the LED driver of at least about 0.8.

An elongated LED lamp suitable for replacing a fluorescent lamp in a lamp fixture comprises a chassis having a first chassis end with two electrodes adapted to be respectively coupled to two electrodes in the lamp fixture supplying AC power, and a second chassis end. A light source depends from the chassis. A power regulating circuit is mounted to the chassis and is coupled to the two electrodes for providing DC power to the first light source. A first light collector conditions the light it collects light from the first light source for TIR propagation within a side-light distribution arrangement. An elongated side-light distribution portion depends from the chassis and receives light exiting the first light collector. Light-extraction structure extract light from the side of the first portion, along a length of the first portion, in a different direction from the direction of light received from the first light collector.

Disclosed is a method of making solar collector assemblies for photovoltaic conversion. The method comprises providing a mold for receiving encapsulant, the mold having serially arranged, alternating peaks and valleys. A respective PV solar cell is placed into each of a series of the valleys such that the light-receiving surfaces of the PV solar cells face upwards. Uncured encapsulant is delivered into the mold and onto the light-receiving surfaces, and from the light-receiving surfaces to a level at least as high as the peaks so as to form, above the light-receiving surfaces, optical concentrators for concentrating light received by the optical concentrators and directing the light to the light-receiving surfaces. The encapsulant is then cured.

An elongated LED lighting arrangement comprises an elongated light pipe with homogeneous optical material between first and second ends. In an exemplary embodiment, an LED provides blue light to the light pipe via a first dichroic mirror tuned to pass blue light. Down-converting means on sidewall of the light pipe, tuned to receive blue light, absorbs blue light from the LED and to emit lower-energy light outside of the light pipe at respectively higher wavelengths. Light-extracting means on the sidewall extract from the light pipe some blue light without changing the wavelengths of the foregoing light. Light from the down-converting means and the light-extracting means are combined to provide a composite color. The first dichroic mirror receives some light emitted by the down-converting means and reflects back into the light pipe more than 80 percent of the light received by the mirror.

Elongated LED lighting arrangement

Elongated lighting system comprises an elongated light pipe having first and second ends, with light supplied to those ends by at least one light source, via first and second light couplers that condition light to increase reflections within the light pipe. Light-extraction structure on the light pipe extracts light from the side of the pipe. An indentation in the light pipe has a depth and has surfaces oriented with respect to the pipe so as (1) to redirect light from the first light source that reaches the indentation after passing once through a plane adjacent the indentation, back through the plane and towards the first end; and (2) to sufficiently increase the average angular distribution of light reflected from the indentation and passing back through the plane as would cause at least 50 percent more reflections of the foregoing light within the pipe in the absence of the light-extraction structure.

Disclosed is a method of making an arrangement for collecting or emitting light. A flexible sheet of material serves as substrate for a plurality of light collecting or emitting devices mounted in spaced relation on the sheet. The sheet has thereon electrical leads for interconnection to each device. For each device, a respective light coupler is formed by (1) forming a plurality of reflectors on the sheet around the intended periphery of the respective device, by applying reflective material to selected areas of the sheet; (2) forming cut lines around selected edges of the plurality of reflectors; (3) forming fold lines associated with the reflectors; and (4) folding the reflectors and attached substrate away from the substrate portion on which the device is mounted, to form a coupler whose interior is reflective and that is substantially closed around a main axis of light propagation into or from the respective device.

Method of making an arrangement for collecting or emitting light

An LED lighting arrangement comprising at least one LED, for producing light is disclosed. A power supply provides power for the at least one LED. At least one control circuit is coupled to the at least one LED in a way that directly or indirectly uses, to power the at least one control circuit, one or more forward voltage drops across the at least one LED. Beneficially, one or more additional control circuits can be added without redesign of the power supply for the at least one LED.
