Abstract
An LED lamp that includes a piezoelectric fan or synthetic jet to cool component of the lamp is disclosed.
Claims31
A lamp system comprising:
- a housing;
- a plurality of LEDs;
- a heat sink connected to the housing and in thermal communication with the plurality of LEDs;
- a flexible blade connected to the housing and having a free end spaced from a surface of the heat sink, the blade being moveable to generate a fluid current to cool the heat sink;
- an electronic actuator operatively associated with the blade for providing a force to oscillate the blade;
- and
- circuitry connected to the LEDs and the electronic actuator, the circuitry configured to receive source power from a source to deliver a first power to the electronic actuator and a second power to the plurality of LEDs.
4 more elements
A lamp comprising:
- a frame;
- a support connected to the frame and including circuitry;
- a plurality of LEDs attached to the support for receiving power from the circuitry, the LEDs being arranged to generate a beam pattern;
- a heat sink contacting the support, wherein the LEDs transfer heat into the heat sink;
- and
- a flexible blade arranged with respect to the heat sink for oscillatory movement where the blade does not interrupt the beam pattern that is generated by the plurality of LEDs;
- and
- an electronic actuator operatively associated with the blade for causing back and forth movement of the blade.
5 more elements
A lamp comprising:
- an enclosure including a translucent portion;
- an electrical connector attached to the enclosure, the connector being configured to electrically connect to an external power source;
- an LED disposed in the enclosure and in electrical communication with the electrical connector;
- a blade disposed in the enclosure and arranged to move back and forth to generate a current to cool the LED;
- and
- a electronic actuator in electrical communication with the electrical connector and operatively associated with the blade for inducing back and forth movement of the blade.
