PURPOSE: A fountain lamp is provided to improve heat discharge performance by forming a first circuit board and a second circuit board with thermal conductive metal. CONSTITUTION: A fountain lamp includes a first circuit board(10) and an upper board(20). A plurality of light emitting units(30) are mounted on the first circuit board. The upper board is arranged on the first circuit board. The upper board reflects the light emitted from the light emitting units. The upper board includes a board body(21), a plurality of penetration holes(22), and a second circuit board. The second circuit board is bonded in the lower surface of the board body and is electrically connected to the first circuit board. The second circuit board drives the light emitting units. The first and second circuit boards are made of thermal conductive metal. |
