Abstract:
The lighting device disclosed at an embodiment of the invention comprises: a reflective member; a resin layer disposed on the reflective member; a light emitting device disposed to correspond to one side surface of the resin layer; and a light wavelength conversion layer disposed on one surface of the resin layer. The light wavelength conversion layer includes a main phosphor pattern disposed in a long axis direction of the resin layer, the main phosphor pattern includes a first unit-phosphor pattern disposed in a first region and a second unit-phosphor pattern disposed in a second region, the first region may be located closer to the light emitting device than the second region, and a width of the first unit-phosphor pattern may be less than a width of the second unit-phosphor pattern.
