PURPOSE: A passive radiator and a radiation device for a street light are provided to increase an effective heat dissipation area by arranging a plurality of heat radiation cross sections on a heat radiation base plate with a matrix shape. CONSTITUTION: An upstanding plate is attached to a heat radiation base plate(3) with soldering. When the heat radiation base plate is mounted, the upstanding plate has a first angle based on the upstanding plate. A heat absorbing cross section(12) is arranged in one side of the heat radiation base plate. A heating component is mounted on the heat absorbing cross section. Radiation fins(4) are attached to the surface of the upstanding plate with the soldering. When the heat radiation base plate is mounted, the radiation fins have a second angel based on the horizontal surface. |
