Abstract
A lighting module according to an embodiment of the invention includes: a substrate; a plurality of light emitting devices disposed in N rows (N is an integer of 1 or more) on the substrate; a first resin layer covering the plurality of light emitting devices; a first diffusion layer disposed on the first resin layer and diffusing light emitted from the first resin layer; and a second diffusion layer disposed on the first diffusion layer and diffusing light emitted from the first diffusion layer, wherein the first diffusion layer includes a diffusing agent, and the second diffusion layer includes at least one of a phosphor and ink particles.
Claims20
A lighting module comprising:
- a substrate;
- a plurality of light emitting devices disposed on the substrate in N rows (N is an integer of 1 or more);
- a first resin layer molding the plurality of light emitting devices;
- a first diffusion layer disposed on the first resin layer and diffusing light emitted from the first resin layer;
- and
- a second diffusion layer disposed on the first diffusion layer and diffusing light emitted from the first diffusion layer,
- wherein the first diffusion layer comprises a diffusing agent,
- wherein the second diffusion layer comprises a phosphor,
- an interval between the plurality of light emitting devices is equal to or greater than a thickness of the first resin layer,
- wherein light emitted to an outside through the second diffusion layer has a light uniformity of 90% or more.
A lighting module comprising:
- a substrate;
- a plurality of light emitting devices on the substrate;
- a first resin layer for molding the plurality of light emitting devices;
- and
- a second resin layer comprising ink particles on the first resin layer,
