1. A lighting device, comprising:
a light source module; and
a sensor emitting and receiving signals to detect objects and spaced apart from the light source module,
wherein the light source module includes:
a substrate of which a lower surface is spaced apart from the sensor, such that the signals from the sensor are transmitted through the substrate and are received to the sensor through the substrate;
a plurality of light sources mounted on an upper surface of the substrate;
a resin layer disposed on the upper surface of the substrate to cover the plurality of light sources; and
a reflective layer disposed between the substrate and the resin layer, and having a plurality of reflective patterns on an upper surface of the substrate.
