Abstract
A lamp device applied to a vehicle may include a flow change generation device which accelerates an air flow in a space around a heat sink dissipating the heat due to the radiation of the light of a light source of an optical module to form the flow enhancing heat-dissipation efficiency of the heat sink, and generates the flow by the shake due to any one of an inertia force of a vehicle, a magnetic force, and a combination of the inertial force of the vehicle and the magnetic force, enhancing heat-dissipation efficiency by the heat dissipation using a change in the flow around a heat source together with the heat dissipation due to the heat sink.
Claims19
A lamp apparatus comprising:
- an optical module having a light source of radiating light;
- a heat sink for dissipating a heat caused by the light source, by an air flow;
- and
- a flow change generation device generating a flowage of a fluid by a flowage movement of the fluid due to an inertia force of a vehicle, and dispersing the heat into the air flow;
- and
- an electromagnet, wherein the flow change generation device causes the flowage movement by a magnetic force of the electromagnet by supplying a power from a power source to the electromagnet.
