Patent ID: 8529099

Claim:
A heat dissipating lamp device, comprising: a lamp housing ( 101 ); a heat dissipation structure ( 102 or 1020 ); an electric turbine axial fan ( 200 ) driven by an electric motor ( 202 ) and installed on a top portion of the heat dissipation lamp housing ( 101 ), so that when the electric turbine axial fan ( 200 ) is operated, airflow is concentrated from an outside of the top portion of the lamp housing ( 101 ), which is relatively hotter, towards a center of the lamp housing ( 101 ), and guided to upwardly enter an axial airflow inlet port ( 208 ) formed at a bottom of the electric turbine axial fan ( 200 ), thereby being exhausted to surroundings of the lamp device through radially-arranged exhaust blades ( 207 ), wherein: the lamp housing ( 101 ) is constituted by a bowl-shaped structure reversely disposed, and configured by a heat conductive member or non-heat conductive member, a top center of the lamp housing ( 101 ) and the heat dissipation structure ( 102 or 1020 ) being formed in a round shape or conical shape and having vertical radial blades integrally formed or assembled with each other, a bottom of the heat dissipation structure ( 102 or 1020 ) allows a lamp to be installed, and the lamp housing ( 101 ) being formed with an annular arc-shape airflow guide surface ( 103 ) along a periphery of the heat dissipation structure ( 102 or 1020 ); and electric turbine axial fan ( 200 ) is constituted by a turbine driven by a built-in electric motor ( 202 ) and having radially-arranged exhaust blades ( 207 ), a bottom of a static part of electric motor being installed on a top portion ( 104 ) of the heat dissipation structure ( 102 or 1020 ) and spaced by a heat insulation member ( 204 ), a rotation shaft ( 206 ) of a rotary part of electric motor being upwardly extended for serving as a core shaft for driving the turbine having the radially-arranged exhaust blades ( 207 ), the bottom of the electric turbine axial fan ( 200 ) being formed with the axial fluid inlet port ( 208 ) for enabling the fluid passing the annular arc-shaped airflow guide surface ( 103 ) of the lamp housing ( 101 ) to pass through the periphery of the top of the heat dissipation structure ( 102 or 1020 ) and then be exhausted to the surroundings through the radially-arranged exhaust blades ( 207 ), and the top of electric turbine axial fan ( 200 ) being provided with a sealed top cover ( 209 ) for providing protection to the electric motor ( 202 ).
