Abstract
The lighting device disclosed in the embodiment of the invention includes a substrate; a plurality of light emitting devices disposed on the substrate and emitting light in at least a first direction; a resin layer sealing the plurality of light emitting devices; and an optical member disposed on the resin layer, wherein the resin layer may include a first light blocking portion integrally formed with the resin layer and having a transmittance lower than that of the resin layer on an emission-side region of each of the plurality of light emitting devices.
Claims20
A lighting device comprising:
- a substrate;
- a plurality of light emitting devices disposed on the substrate and emitting light in a first direction;
- a resin layer sealing the plurality of light emitting devices;
- first light blocking portions disposed on an upper surface of the resin layer;
- and
- an optical member disposed on the upper surface of the resin layer and upper surfaces of the first light blocking portions,
- wherein each of the first light blocking portion has a pattern,
- wherein at least a portion of the first light blocking portions overlaps at least one of the light emitting devices in a thickness direction of the substrate,
- wherein an emission surface of each of the light emitting devices is one side, faces a side surface of the resin layer, and emits light with a highest intensity toward the side surface of the resin layer,
- wherein an upper surface and other sides except for the emission surface of each of the light emitting device are provided with a reflective material and are in direct contact with the resin layer, and
- wherein each of the first light blocking portions has a first region having a first thickness from the upper surface of the resin layer and a second region having a second thickness thinner than the first thickness from the upper surface of the resin layer.
A lighting device comprising:
- a substrate;
- a plurality of light emitting devices disposed on the substrate and emitting light in a side direction;
- a resin layer sealing the plurality of light emitting devices;
- a first light blocking portion disposed on an upper surface of the resin layer;
- and
- an optical member disposed on the upper surface of the resin layer and an upper surface of the first light blocking portion,
- wherein the first light blocking portion has a pattern,
- wherein at least one of the pattern overlaps each of the light emitting devices in a thickness direction of the substrate,
- wherein the first light blocking portion has a first portion that overlaps at least one of the light emitting devices in a vertical direction and a second portion that does not overlap each of the light emitting devices in the vertical direction,
- wherein the thickness direction of the substrate is the vertical direction,
- wherein an emission surface of each of the light emitting devices is one side, faces a side surface of the resin layer, and emits light with a highest intensity toward the side surface of the resin layer,
- wherein an upper surface and other sides except for the emission surface of each of the light emitting device are provided with a reflective material and are in direct contact with the resin layer, and
- wherein the first light blocking portion has a first region having a first thickness from the upper surface of the resin layer and a second region having a second thickness thinner than the first thickness from the upper surface of the resin layer.
