Abstract
An LED light assembly includes a housing, an LED disposed in the housing, a heat dissipating structure and a fluid current generator. The LED is in thermal communication with the heat dissipating structure and includes a flow path surface. The fluid current generator is disposed in the housing to create a current over the flow path surface.
Claims42
An LED light assembly comprising:
- a housing;
- an LED disposed in said housing;
- a heat dissipating structure in thermal communication with said LED;
- a fluid current generator disposed in said housing for creating a current over said heat dissipating structure, wherein said fluid current generator includes a piezoelectric material.

An LED light assembly comprising:
- a housing;
- an LED disposed in said housing;
- a heat sink disposed in said housing, said LED being mounted to said heat sink and in thermal communication with said heat sink;
- and
- a synthetic jet actuator disposed in said housing for generating a current of fluid over said heat sink to cool said LED.
2 more elements
An LED light assembly comprising:
- a heat sink;
- a support mounted to said heat sink;
- an LED mounted to said support, said LED conducting heat through said support and into said heat sink;
- and

2 more elements
An LED light assembly comprising:
- a housing;
- an LED disposed in said housing;
- a fluid current generator disposed with respect to said LED for creating a fluid current to cool said LED, wherein said fluid current generator includes a piezoelectric material, a first flexible side plate and a second flexible side plate, the first flexible side plate and the second flexible side plate connected by a flexible hinge.
An LED light assembly comprising:
- a housing;
- an LED disposed in said housing;
- and
- a synthetic jet actuator disposed in said housing for generating a current of fluid to cool said LED, the synthetic jet comprising a body having an fluid cavity and at least two movable elements for increasing and reducing the volume of the fluid cavity to generate the current of fluid.
