20140203939 | CONTROL AND MONITORING OF LIGHT-EMITTING-DIODE (LED) BULBS - A smart light-emitting-diode (LED) bulb includes apparatus enabling the bulb to be turned ON, OFF, or dimmed without the use of a wall switch. Such apparatus may include circuitry responsive to rotating the LED portion of the bulb, circuitry responsive to touching or tapping on the bulb, or a Bluetooth or WiFi interconnection enabling the bulb to be controlled using a smartphone or other device executing a bulb-control application. Other apparatus may include a microphone enabling the bulb to be controlled with a voice, sound or music. In other embodiments, apparatus enabling the bulb to be turned ON, OFF, or dimmed may include a power line communication (PLC) interface enabling the bulb or bulbs to be controlled via the Internet. A camera or image sensor may be provided enabling the bulb to be gesture-controlled. A system may include a plurality of smart LED light bulbs. | 07-24-2014 |
20130193861 | LIGHT EMITTING DIODE CIRCUITS FOR GENERAL LIGHTING - Improved circuits minimize, or eliminate, energy losses in the supply of energy to control LEDs. Diodes and a capacitor reduce or eliminate LED blinking, and create smooth and continuous, infinitely variable dimming. The components are added to supply power to each LED during the half of the AC cycle where it would normally be turned off. A first added diode allows an added capacitor to charge during the half cycle that the original diode is turned on, but does not allow the other half cycle to discharge the added capacitor. When the added capacitor is charged enough to turn on the original diode, it stays on throughout the AC cycle. The same relationship exists between the second added diode, the added capacitor and the second original diode. Zener diodes protect the LEDs from voltage surges/spikes by shunting current around LEDs when the voltage exceeds the Zener diode's breakdown voltage. | 08-01-2013 |
