Claim:
1. A lighting apparatus comprising: a light source configured to emit light; a controller configured to control operation of the light source in response to an external control signal; a non-contact sensor configured to detect a non-contact signal; and a communication interface configured to communicatively connect the lighting apparatus to a wireless network to receive the external control signal from a remote apparatus via the wireless network, wherein the controller turns the light source on/off or changes at least one of a color temperature, chroma, or brightness of the light emitted from the light source in response to the external control signal, wherein the light source comprises: wherein the one or more light emitting devices comprise a phosphor, a first conductive semiconductor layer, an active layer, a second conductive semiconductor layer, a second electrode layer, an insulating layer, and a first electrode layer that are sequentially stacked, wherein the first electrode layer comprises one or more contacts that are electrically insulated from the second conductive semiconductor layer and the active layer and that extend from a surface of the first electrode layer to a portion of the first conductive semiconductor layer in order to be electrically connected to the first conductive semiconductor layer, and the phosphor generates a white light having a color temperature in a range from 1500° K to 20000°, and wherein the communication interface comprises:
