A storage system is disclosed where goods can be stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of rails (e.g., tracks) on which load handling devices can run. To take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked. The framework may be provided with one or more of the following exemplary services: power, power control, heating, lighting, cooling, sensors, and data logging devices. The provision of these services within the framework rather than across the system as a whole, can allow for flexibility in storage whilst reducing cost and inefficiency.

An assimilation lamp device (101; 800) for stimulating plant and crop growth comprises: a central lamp unit (10), comprising a body (14) and one or more LEDs (12) mounted to the bottom surface of the body, wherein the body acts as a heat sink for the heat generated by the LEDs. The device further comprises air stream generating means (42) for generating a downward air stream (43; 341), and heat transfer and exchange means for transferring heat from the body to the air stream, so that heat from the LEDs is used to increase the temperature of said downward air stream and is eventually used to warm the environment of the plants. A device controller (850) has a set point input (859) and generates control signals for the LEDs and the air stream generating means in conformity with an input signal received at its set point input.

Activation of a far-red light device with a far-red light frequency that promotes the conversion of inactive Pfr to active Pr in short-day plants prior to a dark period.

A bundle beam UV LED ultraviolet light sweeping method includes: activating electrical power to input into a PCB to light up a bundle beam UV LED ultraviolet light bead and driving a motor to cause a polygonal multiple-reflective-surface aluminum mirror to rotate, ultraviolet light from the UV LED being projected toward the reflective surface, and reflected by the reflective surface to change light direction for successive back-and-forth home-position-returning sweeping, the light converting from lines into sectorial shapes that are connected to form a large ultraviolet light operation region. The device includes a rotating device having a motor of which a spindle is mounted with a polygonal multiple-reflective-surface aluminum mirror; an UV LED bundle beam light source assembly having a bundle beam UV LED ultraviolet light bead fixed on a PCB; and a fixing base having a main body and a plurality of mounting braces.

Systems and methods disclosed herein include a method of illuminating plants in an indoor farming environment, including illuminating one or more plants using one or more lighting fixtures at a light intensity of approximately 1500 μmol/m.sup.2/s during a daytime period, wherein each lighting fixtures comprises one or more LEDs, determining whether a daytime temperature of the indoor farming environment is within a daytime temperature range, adjusting the daytime temperature to be within the daytime temperature range in response to determining that the daytime temperature of the indoor farming environment is outside of the daytime temperature range, determining whether a daytime humidity of the indoor farming environment is within a daytime humidity range, and adjusting the daytime humidity to be within the daytime humidity range in response to determining that the daytime humidity of the indoor farming environment is outside of the daytime humidity range.

The present invention provides a method for promoting plant growth, a plant lamp and application thereof. The method at least includes providing an artificial light source for a growing plant. The light source includes a red light with a peak wavelength of 680-695 nm and a light wave half-width lower than 35 nm; or the light source includes a blue light with a peak wavelength of 410-440 nm and a light wave half-width lower than 35 nm. The plant lamp provides the light source for promoting plant growth. By using the light source in the present invention to irradiate the plant, plant growth is significantly promoted.

A Light-Emitting Diode (LED) system for facilitating the growth of a plant includes at least one LED array having one or more LEDs for emitting colored light spectra absorbable by a plant, a light detector for detecting light reflected from the plant, and a LED light driver electrically coupled to the at least one LED array and the light detector. The LED light driver receives electrical power from a power source and drives the at least one LED array using the received electrical power; receives from the light detector a signal indicative of the reflected light spectra, and controls the at least one LED array to adjust at least one of the intensities and the spectra of the light emitted from the at least one LED array, based on the received signal.

The present invention relates to the technical field of lighting for plant, and in particular, provides a multi-reflection panel lamp. The multi-reflection panel lamp includes a fixing frame, a plurality of panel lamps, and a plurality of reflectors. The plurality of panel lamps are embedded in the fixing frame parallel to each other. The reflectors and the panel lamps are parallelly disposed on the fixing frame. Compared to other panel lamps, in the present invention, reflectors are disposed between panel lamps to reflect, a plurality of times by using a multi-refraction mechanism of the reflectors of the panel lamps, rays of light emitted by the panel lamps, so that plants are irradiated with the rays of light at various angles, thereby improving lighting intensity and uniformity and ensuring normal growth of the plants.
