High-performance high-power LED lighting systems and methods thereof

A lighting apparatus comprising:

• at least a first printed circuit board (PCB) comprising one or more first openings;
• and
• a housing receiving the at least first PCB therein;
• wherein the housing comprises a rear-wall structure on a rear side of the at least first PCB, the rear-wall structure comprising one or more second openings and a plurality of spaced fins extending rearwardly from the rear side of the rear-wall structure and extending continuously from one side of the one or more second openings over the one or more second openings to an opposite side of the one or more second openings such that the one or more first openings, the one or more second openings, and spaces between the plurality of spaced fins form a straight air path through the at least first PCB for dissipating heat generated from the at least first PCB;
• and
• wherein a first set of the plurality of fins extend between an opposite pair of edges of the rear-wall structure and over the one or more second openings;
• and wherein a second set of the plurality of fins extend from an outermost fin of the first set of the plurality of fins towards an edge of the rear-wall structure adjacent the outermost fin.

A lighting apparatus comprising:

• a housing;
• and
• at least one printed circuit board (PCB) received in the housing;
• wherein the at least one PCB comprises one or more first openings and one or more light-emitting components distributed on a front side thereof about the one or more first openings;
• wherein the housing comprises a rear-wall structure on a rear side of the at least one PCB, the rear-wall structure comprising one or more second openings and a plurality of spaced fins extending rearwardly from the rear side of the rear-wall structure and extending continuously from one side of the one or more second openings over the one or more second openings to an opposite side of the one or more second openings such that the one or more first openings, the one or more second openings, and spaces between the plurality of spaced fins form a straight air path through the at least first PCB for dissipating heat generated from the at least first PCB;
• and
• wherein a first set of the plurality of fins extend between an opposite pair of edges of the rear-wall structure and over the one or more second openings;
• and wherein a second set of the plurality of fins extend from an outermost fin of the first set of the plurality of fins towards an edge of the rear-wall structure adjacent the outermost fin.
