An LED column-type street lamp(3) is set up in vertical direction to the ground while having more than two LED bars. A pillar(11) of the cylindrical shape comprises a hollow interior and a annular stepped portion formed in the upper inner cylindrical surface which sets the pillar in vertical direction to the ground. A base plate is arranged between the pillar and the ground to fix the pillar to the ground in vertical direction. A reinforcing support(15) is adhered to the outer circumference of pillar and top of the base plate.</p> |
