Arc modular light devices, systems, and methods

#Embodiments disclosed herein relate generally to light fixtures, and in particular to LED light fixtures.

#Recent decades have seen an accelerating shift toward the use of light-emitting diodes (LEDs) in light fixtures. Compared to other forms of electrical light, such as fluorescent and incandescent lighting, LEDs are extremely energy efficient, reducing electrical bills and reducing the environmental impact of energy used for lighting. LEDs also have much longer useful lifespans than most other forms of electrical lighting, especially when compared to lighting suitable for indoor use. In the past LEDs also had certain disadvantages, such as the tendency to emit light in narrow ranges of wavelengths, often seeming monochromatic, and difficulty matching the luminous power of incandescent and fluorescent lights. As the use of LEDs has expanded, firms across the globe have raced to improve LEDs, shoring up many of their traditional weaknesses. LEDs that produce more lumens and LEDs that produce broader spectra of light have become increasingly ubiquitous and inexpensive. Nonetheless, where a high luminous output, a broad spectrum of wavelengths, or both are desired, LEDs still cannot match competing technologies. For instance, indoor horticulture using artificial light requires high-intensity light with a broad range of wavelengths as a substitute for the sunlight plants naturally crave. Currently available LED fixtures often fail to achieve those requirements, forcing indoor horticulturalists to select less energy-efficient options.

#According to one aspect, a modular lighting fixture includes a housing having a front panel, the front panel having a radius of curvature, and a plurality of LED modules disposed adjacent the front panel. Each of the LED modules includes a heat sink, an LED source mounted to the heat sink, and a lens disposed over the LED source, the lens capable of refracting light emitted by the LED source into a desired distribution pattern. The plurality of LED modules produce a concentrated illuminated area at a pre-determined distance from the front panel as determined by the radius of curvature of the front panel. The heat sink of each LED module may have an internal volume defined by a closed end, a sidewall, and an open end, and the LED source may be mounted within the volume and positioned to emit light toward the open end.

#The disclosed embodiments and other features, advantages, and disclosures contained herein, and the matter of attaining them, will become apparent and the present disclosure will be better understood by reference to the following description of various exemplary embodiments of the present disclosure taken in conjunction with the accompanying drawings, wherein:

#FIG. 1 shows an isometric view of an embodiment of an arc modular LED light fixture according to the present disclosure;

#FIG. 2 shows a cut-away plan view of an embodiment of an arc modular LED light fixture according to the present disclosure.

#An overview of the features, functions and/or configurations of the components depicted in the various figures will now be presented. It should be appreciated that not all of the features of the components of the figures are necessarily described. Some of these non-discussed features, such as various couplers, etc., as well as discussed features are inherent from the figures themselves. Other non-discussed features may be inherent in component geometry and/or configuration.

#The present application discloses various embodiments of an arc-shaped modular light emitting diode (“LED”) light fixture and methods for using and constructing the same. According to one aspect of the present disclosure, an arc modular fixture array having a plurality of LED modules, suitable for horticulture, aquaculture, and general area light is disclosed. For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of this disclosure is thereby intended.

#FIG. 1 shows an arc modular LED light fixture 100 according to at least one embodiment of the present disclosure. As shown in FIG. 1, the fixture 100 may include a housing 10 having a back panel 14 and a front panel 12 joined together by one or more side panels 16. The front panel 12 may have a curved or arced shape in profile that defines a substantially uniform radius of curvature between the side panels 16. The back panel 14 may be similarly arced in profile, though the radius of the back panel 14 need not be identical to the radius of the front panel 12. In some embodiments, the back panel 14 may be substantially flat. The housing 10 may include one or more vents 18 formed therethrough to enable the flow of ambient air into, through, and out of the housing 10.
