LED STREETLIGHT LAMP HEAD

摘要

PURPOSE: An LED street light lamp-head is provided to form a compact structure by improving heat dissipation efficiency for a high power lamp with high output, and to be equipped safely on a street light pole by a connection part and a wire. CONSTITUTION: A LED street light lamp-head(100) comprises a housing(110), a PCB substrate(130), a heat sink(120), a glass(150), a glass cover(152), and an LED driver. The housing includes a linking groove which is connected to a horizontal strut of a street light pole. The housing is formed in a hollow shape through a center. The heat sink is settled at an upper side of the housing. Several joint grooves for tightening the PCB substrate are formed on the central part of a seating surface. The PCB substrate(130) is linked to the seating surface of the heat sink, accommodates an LED package at one side , and forms a pattern to supply power to the LED package.
