High-power LED street lamp with weak light error and method for manufacturing it

摘要

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