Abstract: A modular lighting fixture for controlled environment agriculture includes an elongate body with first and second connectors at opposite ends, and end plates having opposite low voltage charges. The fixture includes a beam removably coupled to the end plates via electrically conductive fasteners, with LED strips mounted to the beam and in wired electrical communication with the electrically conductive fasteners. A first power source powers the LED strips through the end plates, while a separate second power source operates a stroboscopic light source. The system enables easy LED strip interchangeability, adjustable beam angles for optimized light distribution, and dimming capabilities through a primary voltage circuit. The stroboscopic light source provides high-intensity illumination across an extensive spectrum range while operating at a reduced wattage.

Abstract: A lighting system in which a housing is provided to support a curved lamp tube and includes a curved base plate to conform with the curve of the lamp tube. Two corners members are connected to the base plate and are curved to conform to the curve of the base plate, and two side walls are respectively connected to the two corner members and are curved to conform to the curve of the corner members. A support plate is supported by the side walls and curved to conform to the curve of the base plate for supporting the lamp tube.
