Linear lighting systems and processes

A linear lighting system, comprising:

• a tray being extended along elongation directions and having a base forming a bottom interior surface of the tray, a first sidewall including an angled reflective face and extending upward from the base towards an emission aperture of the linear lighting system, and a second sidewall including a further angled reflective face and extending upward from the base towards the emission aperture of the linear lighting system, the second sidewall being spaced apart across the base from the first sidewall;
• a circuit board being located on the first sidewall in the tray, and another circuit board being located on the second sidewall in the tray;
• a plurality of light emitting diodes (LEDs) being located on the circuit board and mutually spaced apart on the first sidewall along the elongation directions of the tray and being positioned for light emissions in directions facing toward the second sidewall, and another plurality of light emitting diodes (LEDs) being located on the another circuit board and mutually spaced apart on the second sidewall along the elongation directions of the tray and being positioned for further light emissions in directions facing toward the first sidewall;
• wherein the further angled reflective face of the second sidewall is positioned for reflecting light emissions from the plurality of the LEDs toward the emission aperture;
• and
• wherein the angled reflective face of the first sidewall is positioned for reflecting further light emissions from the another plurality of the LEDs toward the emission aperture.
