Abstract

An LED device for use with an AC voltage power source configured such that at least one LED emits light during a positive phase of power provided from an AC power supply and at least one LED emits light during the negative phase of power provided from an AC power supply. The LED device includes a first power connection lead and a second power connection lead, both leads capable of being connected to and receiving power from an AC power supply.

Claims

1. An apparatus comprising:

an LED circuit having at least one LED, wherein the at least one LED is an organic LED;

a data communications circuit having an antenna, wherein the data communication circuit is configured to transmit or receive data signals, and wherein the antenna is configured to transmit or receive alternating signals;

a circuit configured to detect touch via capacitive sensing, the touch being of a person; and

a power supply configured to increase a power supplied to the LED circuit when the circuit detects the touch; and

wherein the apparatus is portable.

2. The apparatus of claim 1, wherein the data communications circuit has no continuous DC conductive path.

3. The apparatus of claim 1, wherein the data communications circuit has a continuous DC conductive path.

4. The apparatus of claim 3, wherein the apparatus is a signal output device.

5. The apparatus of claim 3, wherein the data communications circuit further comprises:

a modem.

6. The apparatus of claim 3 further comprising:

a heat sink.

7. The apparatus of claim 3, wherein the at least one LED is mounted on a glass substrate.

8. A method of operating a portable apparatus, the method comprising:

transmitting or receiving data signals wirelessly;

detecting touch via capacitive sensing, the touch being of a person; and

increasing a level of power to an LED circuit comprising at least one LED in the portable apparatus upon detection of the touch.

9. The method of claim 8 further comprising:

decreasing the level of power to the LED circuit when a user of the portable apparatus controls a switch.

10. The method of claim 9, wherein the switch is a dimmer switch.

11. The apparatus of claim 9, wherein the switch is a 3-way switch.

12. An apparatus comprising:

an LED circuit having at least one LED;

a data communications circuit having an antenna, wherein the data communication circuit is configured to transmit or receive data signals, and wherein the antenna is configured to transmit or receive alternating signals;

a switch configured to control the at least one LED circuit; and

a power supply configured to decrease or turn off power to the LED circuit when a user of the apparatus controls the switch; and
