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.

Abstract: A light emitting device includes: a frame having an opening; at least one light emitting diode (LED) disposed on the frame; a reflector disposed on the frame; and a reflective protrusion projecting from the reflector, wherein light emitted from at least one light emitting diode is reflected by the reflector through the opening, wherein the vertical axis of the reflective protrusion is perpendicular to a plane formed by extending the upper surface of the frame, wherein the upper surface of the frame contacts the reflector, and wherein a distance between two LEDs with one LED placed therebetween is greater than a distance between one LED and the reflector. Because a light source is disposed on the frame of the light emitting device, it is possible to easily exchange the light source of the light emitting diode by removing and attaching the frame without disassembling the entire lighting device.
