Lighting apparatus

1. A lighting apparatus comprising:

a control module supplying power;

a heat sink receiving the control module;

a light source mounted on the heat sink and connected to the control module; and

a communication module including a substrate on which an antenna device is disposed,

wherein a connection terminal is provided on the substrate,

wherein an insertion hole is formed in the heat sink and the substrate extends by passing through the insertion hole such that the connection terminal is inserted into the heat sink and the antenna device protrudes from the heat sink, and

wherein the control module comprises a coupling terminal to receive the connection terminal for connecting the communication module to the control module.

2. The lighting apparatus of claim 1 , wherein the antenna device is spaced apart from the heat sink.

3. The lighting apparatus of claim 1 , wherein the substrate comprises:

a connection region on which the connection terminal is disposed; and

an antenna region on which the antenna device is disposed.

4. The lighting apparatus of claim 3 , wherein the communication module further comprises a driving device connecting the connection terminal to the antenna device and driving the antenna device.

5. The lighting apparatus of claim 1 , wherein the communication module further comprises a protective cover covering the substrate to receive the antenna device, and exposing the connection terminal.

6. The lighting apparatus of claim 4 , wherein the substrate further comprises a ground part disposed at the connection region and spaced apart from the connection terminal while making contact with the antenna device through the driving device.

7. The lighting apparatus of claim 4 , wherein the substrate further comprises a driving region interposed between the connection region and the antenna region, the driving device being disposed on the driving region.

8. The lighting apparatus of claim 5 , wherein the protective cover comprises:

a first protective cover inserted into the heat sink; and

a second protective cover coupled with the heat sink and protruding from the heat sink.

9. The lighting apparatus of claim 2 , wherein a spacing distance between the heat sink and the antenna device is 1 mm or more.

10. The lighting apparatus of claim 1 , wherein the control module further comprises a feeding terminal connected to the light source.

11. A lighting apparatus comprising:

a control module supplying power;

a heat sink receiving the control module;

a light source mounted on the heat sink to emit light according to the power; and

a communication module receiving a signal for controlling the control module,

wherein the communication module comprises:

a substrate;

a connection terminal disposed on the substrate, inserted into the heat sink, and connected to the control module; and

an antenna device disposed on the substrate and protruding from the heat sink to be spaced apart from the heat sink,

wherein an insertion hole is formed in the heat sink and the substrate extends by passing through the insertion hole such that the connection terminal is inserted into the heat sink and the antenna device protrudes from the heat sink, and

wherein the control module comprises a coupling terminal to receive the connection terminal for connecting the communication module to the control module.

12. The lighting apparatus of claim 11 , wherein the communication module further comprises a driving device connecting the connection terminal to the antenna device and driving the antenna device.

13. The lighting apparatus of claim 12 , wherein the communication module further comprises a ground part spaced apart from the connection terminal, and making contact with the antenna device through the driving device.

14. The lighting apparatus of claim 13 , wherein the substrate comprises:

a connection region on which the connection terminal and the ground part are disposed;

an antenna region on which the antenna device is disposed;

a driving region on which the driving device is disposed between the connection region and the antenna region.

15. The lighting apparatus of claim 14 , wherein the communication module comprises:

a first protective cover surrounding the driving region; and

a second protective cover coupled with the heat sink, and protruding from the heat sink.

16. The lighting apparatus of claim 11 , wherein the control module further comprises:

a feeding terminal connected to the light source.
