Abstract

Disclosed is a lighting apparatus. The lighting apparatus includes: 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. Since the lighting apparatus can be controlled in a wireless scheme, a user of the lighting apparatus can easily control the lighting apparatus.

Claims
