Abstract
A lighting device may include a base, a housing, a driver circuit, an optic, a thermally-conductive fluid, a LED filament structure, and a fluid flow generator. The base may have an electrical contact. The housing may be attached to the base at a first end and have an internal cavity. The driver circuit may be positioned within the internal cavity and may be in electrical communication with the electrical contact. The optic may be attached to a second end of the housing and have an inner surface which may define an optical chamber. The thermally-conductive fluid may be positioned within the optical chamber. The LED filament structure may be positioned within the optical chamber and may be in electrical communication with the driver circuit. The fluid flow generator may be positioned in fluid communication with the optical chamber and may be in electrical communication with the driver circuit.
