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 connection terminal inserted into the heat sink and connected to the control module, and an antenna device protruding from the heat sink;

wherein the communication module comprises:

a substrate on which the connection terminal and the antenna device are disposed; and

a driving device connecting the connection terminal to the antenna device and driving the antenna device;

wherein the substrate comprises:

a connection region on which the connection terminal is disposed:

an antenna region n which the antenna device is disposed; and

a driving region interposed between the connection region and the antenna region, wherein the driving device is disposed on the driving region.

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 communication module further comprises a protective cover covering the substrate to receive the antenna device, and exposing the connection terminal.

4. The lighting apparatus of claim 1 , 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.

5. The lighting apparatus of claim 3 , 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.

6. The lighting apparatus of claim 1 , wherein the control module comprises a coupling terminal coupled with and connected with the connection terminal.

7. The lighting apparatus of claim 1 , wherein an insertion hole is formed in the heat sink and the substrate extends by passing through the insertion hole.

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

9. The lighting apparatus of claim 6 , wherein the control module further comprises a feeding terminal connected to the light source.

10. 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 the communication module comprises:

a driving device connecting the connection terminal to the antenna device and driving the antenna device; and

a ground part spaced apart from the connection terminal, the ground part making contact with the antenna device through the driving device.

11. The lighting apparatus of claim 10 , 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.

12. The lighting apparatus of claim 11 , wherein the communication module comprises:

a first protective cover surrounding the driving region; and

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

13. The lighting apparatus of claim 10 , wherein an insertion hole is formed in the heat sink and the substrate extends by passing through the insertion hole.

14. The lighting apparatus of claim 10 , wherein the control module comprises:

a coupling terminal coupled with and connected with the connection terminal; and

a feeding terminal connected to the light source.
