An embodiment may include a lighting device comprising: a substrate; a light emitting device disposed on the substrate; a resin layer disposed on the light emitting device and covering the light emitting device; a diffusion layer disposed on the resin layer; an optical pattern disposed between the lower surface of the diffusion layer and the resin layer; and a cover layer surrounding the optical pattern, wherein the cover layer comprises a release agent.

Lighting device

A lighting device disclosed in an embodiment of the invention includes: a first substrate; a first light emitting device disposed on the first substrate; a resin layer disposed on the first substrate; a second substrate disposed on the resin layer; and a second light emitting device disposed on the second substrate and disposed in the resin layer. The resin layer may include a first surface from which light emitted from the first and second light emitting devices is emitted, and the first surface of the resin layer may include a plurality of convex portions and a plurality of concave portions.

Lighting module, lighting device and lamp

A lighting device disclosed in an embodiment of the invention includes a substrate; a light emitting device disposed on the substrate; a resin layer sealing the light emitting device on the substrate; and a diffusion layer or a reflective substrate disposed on the resin layer, wherein the resin layer includes an oligomer, a monomer, and an additive, wherein the monomer includes IBOA (Iso-bornyl Acrylate), two or more dilution monomers and glycidyl methacrylate (GMA), the additive includes a photoinitiator and an amine-based light stabilizer, and in the oligomer and the monomer, the content of glycidyl methacrylate is 10 to 15%, and the resin layer may be a curable transparent resin cured by ultraviolet light.

Optical resin and lighting device having same

In the present invention, there is provided a lighting device including: a light source module including at least one light source and a light guide member that buries the light source; a shielding module accommodating the light source module therein, the shielding module having an opening region and a shielding region, which are provided above the light guide member; and a diffusion member disposed in the light guide member.

Lighting apparatus and vehicular lamp comprising the same

Provided is a lighting device, comprising: a light source module comprising: at least one light source disposed on a printed circuit board; and a resin layer disposed on the printed circuit board so that the light source is embedded; a light reflection member formed on at least any one of one side surface and another side surface of the resin layer; and a diffusion plate having an upper surface which is in contact with an upper part of the light source module, and a side wall which is integrally formed with the upper surface and formed to extend in a lower side direction and which is adhered to the light reflection member, whereby flexibility of the product itself can be secured, and durability and reliability of the product can be also improved.

Provided is a lighting device, comprising: a light source module comprising: at least one light source disposed on a printed circuit board; and a resin layer disposed on the printed circuit board so that the light source is embedded; an indirect light emission unit which is formed in at least any one of one side and another side of the light source module and which reflects light irradiated from the light source; and a diffusion plate having an upper surface which is in contact with an upper part of the light source module, and a side wall which is integrally formed with the upper surface and formed to extend in a lower side direction and which is adhered onto an outer side surface of the indirect light emission unit, whereby flexibility of the product itself can be secured, and durability and reliability thereof can be also improved.
