摘要
A low light failure high power LED street lamp and a manufacturing method therefor. Color mark is made on tail end of N-type semiconductor element (6) or P-type semiconductor element (7); then N-type and P-type semiconductor element (6, 7) are arranged in matrix manner between upper beryllium-oxide ceramic wafer (8) and lower beryllium-oxide ceramic wafer (9), so that head end of N-type semiconductor element (6) is connected with tail end of P-type semiconductor element (7) or tail end of N-type semiconductor element (6) is connected with head end of P-type semiconductor element (7), then lower beryllium-oxide ceramic wafer (9) is attached, through graphene thermal conductive greaseon layer (4), on backside of circuit board (2) which is mounted with LED bulbs (3), and heat sink (15) is mounted on upper beryllium-oxide ceramic wafer (8), then circuit board (2) together with heat sink (15) are mounted into street lamp housing (1).
