1. A method for dissipating heat generated from at least one printed circuit board (PCB) received in a housing of a lighting apparatus during operation, the method comprising:
establishing one or more first openings on the at least one PCB; and
establishing one or more second openings on the housing and a plurality of spaced fins extending rearwardly from a rear side of the housing 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 the heat generated from the at least first PCB;
wherein said arranging the plurality of fins on the rear-wall structure and equidistantly spaced apart from each other comprises:
arranging a first set of the plurality of fins extend between an opposite pair of edges of the rear-wall structure; and
arranging a second set of the plurality of fins extend front an outermost fin of the first set of the plurality of fins towards an edge of the rear-wall structure adjacent the outermost fin.
