Title:
Heat dissipation lamp device
Document Type and Number:
Japanese Patent JP6068888
Kind Code:
B2
Abstract:
The present invention provides an electric turbine axial fan (200), which is rainproof and installed at the top portion of sealed heat dissipation lamp housing (101) of a high power lamp, so when the electric turbine axial fan (200) is operated, the airflow passes through the top portion of lamp housing of the sealed heat dissipation lamp housing (101) and is concentrated towards the center, then leaded to upwardly enter an axial airflow inlet port formed at the bottom of the electric turbine axial fan (200), thereby being exhausted to the surroundings through radially-arranged exhaust blades (207), thus a cooling effect by the external cooling airflow can be provided to the top portion of a high power lamp, which is relatively hotter; when external wind power drives the turbine axial fan, the loading of electric motor can be lowered so as to reduce the electric power outputted by the electric motor.
