Abstract

Provided is a lighting apparatus and a method for controlling the same using a mobile device. A lighting system may include a mobile terminal, a hub configured to communicate with the mobile terminal, and an LED lamp configured to communicate with the hub. The mobile terminal may be configured to display an image captured or focused using a camera at the mobile terminal. The mobile terminal may transfer to the hub information corresponding to a selection of a region of the image. The hub may provide a wireless signal corresponding to the information received from the mobile terminal for changing a color of light emitted by the LED lamp. The LED lamp may be controlled based on the ZigBee communication protocol.

Claims

1. A lighting system comprising:

a mobile terminal;

a hub configured to communicate with the mobile terminal; and

an LED lamp configured to communicate with the hub, wherein

the mobile terminal is configured to display an image captured or focused using a camera at the mobile terminal, and transfers to the hub information corresponding to a selection of a region of the image, and

the hub provides a wireless signal corresponding to the information received from the mobile terminal for changing a color of light emitted by the LED lamp.

2. The lighting system of claim 1, wherein the information transferred to the hub includes information for changing a brightness or color temperature of the light emitted by the LED lamp.

3. The lighting system of claim 1, wherein the information corresponds to a level of a prescribed color based on the selected region of the image.

4. The lighting system of claim 1, wherein the information is based on a mosaic, gradation, or color percentage of the selected region of the image.

5. The lighting system of claim 1, wherein the wireless signal is a control signal based on the ZigBee protocol.

6. The lighting system of claim 1, wherein the information transferred to the hub is a control signal based on the ZigBee protocol.

7. The lighting system of claim 1, wherein the mobile terminal is configured to communicate with the hub according to the TCP/IP protocol.

8. The lighting system of claim 1, wherein the hub is configured to communicate with the lighting apparatus according to the ZigBee protocol.

9. The lighting system of claim 1, wherein the mobile terminal is configured to communicate with the lighting apparatus according to the ZigBee protocol.

10. The lighting system of claim 1, wherein the mobile terminal is a smart phone.

11. An LED bulb comprising:

a lens;

at least one LED provided on a substrate;

a heat sink configured to dissipate heat generated by the LEDs;

a wireless communication module; and

a controller configured to control a color of light emitted by the LEDs,

wherein the controller receives through the wireless communication module information corresponding to a selection of a region of an image captured or focused using a camera at the mobile device, and controls the LEDs to emit a color based on the received information.

12. The LED bulb of claim 11, wherein the information corresponds to a level of a prescribed color based on the selected region of the image.

13. The LED bulb of claim 11, wherein the information is based on a mosaic, gradation, or color percentage of the selected region of the image.

14. The LED bulb of claim 11, wherein the controller receives the information from a hub configured to communicate with the mobile device.

15. The LED bulb of claim 11, wherein the information is a control signal to the LEDs.

16. The LED bulb of claim 15, wherein the control signal generated at a hub configured to communicate with the mobile device.

17. The LED bulb of claim 15, wherein the control signal is received from the mobile device.

18. The LED bulb of claim 15, wherein the control signal is received according to the ZigBee protocol.

19. The LED bulb of claim 11, wherein the plurality of LEDs include a red LED, green LED, and a blue LED, and wherein the information is a control signal that controls each of the red LED, the green LED, and the blue LED.

20. The LED bulb of claim 11, wherein the LED bulb is an omnidirectional bulb.
