Abstract

In a first aspect of the present inventive subject matter, a lighting device includes a substrate, a light-emitting element electrically mounted on the substrate, a frame member including a white-colored resin and surrounding the light-emitting element, and a light-transmitting resin in which the light-emitting element and the frame member are embedded. Also, it is suggested that the frame member further includes a light-shielding member entirely sealed by the white-colored resin.

Claims (52)

1. A lighting device comprising:

a substrate;

a light-emitting element electrically mounted on the substrate;

a frame member comprising a white-colored resin and surrounding the light-emitting element; and

a light-transmitting resin in which the light-emitting element and the frame member are embedded, wherein

the frame member further comprises a light-shielding member, and

the white-colored resin of the frame member comprising a reflective particle entirely seals the light-shielding member.

2. The lighting device according to claim 1 ,

the light-transmitting resin comprises a phosphor.

3. The lighting device according to claim 1 ,

the light-transmitting resin comprises transparent resin.

4. The lighting device according to claim 1 ,

the frame member comprises a sloping surface that faces a peripheral side surface of the light-emitting element.

5. The lighting device according to claim 1 ,

the frame member has a square ring shape in a top plan view.

6. The lighting device according to claim 1 ,

the light-shielding member of the frame member comprises a black-colored resin, and

the white colored resin of the frame member entirely seals the black-colored resin.

7. The lighting device according to claim 1 ,

the light-shielding member of the frame member comprises a metal powder.

8. The lighting device according to claim 1 ,

the light-shielding member of the frame member comprises a graphite powder.

9. The lighting device according to claim 1 ,

the reflective particle included in the white-colored resin of the frame member is titanium oxide particle.

10. The lighting device according to claim 1 ,

the light-shielding member of the frame member comprises a metal frame embedded in the white-colored resin of the frame member.

11. The lighting device according to claim 1 ,

the light-shielding member of the frame member comprises a sloping surface inside the white-colored resin of the frame member.

12. The lighting device according to claim 1 ,

the light-transmitting resin further comprises a first light-transmitting resin and a second light-transmitting resin,

the first light-transmitting resin includes a phosphor and is arranged as a phosphor layer covering an upper surface and a peripheral side surface of the light-emitting element, and

the second light-transmitting resin entirely seals the light-emitting element on the substrate, the frame member on the substrate, and the first light-transmitting resin arranged as the layer covering the upper surface and the peripheral side surface of the light-emitting element.

13. The lighting device according to claim 1 ,

the frame member comprises a silicone resin as a primary material, and the light-transmitting resin comprises a silicone resin as a primary material.

14. A lighting device comprising:

a substrate;

two or more light-emitting elements electrically mounted on the substrate;

a frame member comprising a white-colored resin and two or more openings each in which at least one light-emitting element of the two or more light-emitting elements is arranged; and

a light-transmitting resin in which the light-emitting element and the frame member are embedded, wherein

the frame member further comprises a light-shielding member that is embedded in the white-colored resin of the frame member.

15. The lighting device according to claim 14 ,

the two or more openings of the frame member are aligned in a line.

16. The lighting device according to claim 14 ,

the two or more openings of the frame member are arranged in a shape of grid.

17. The lighting device according to claim 14 ,

the frame member further comprises a sloping surface.

18. A method of manufacturing a lighting device comprising:

electrically mounting a light-emitting element on an upper surface of a substrate;

arranging a frame member, which comprises a light-shielding member embedded in a white-colored resin, on the upper surface of the substrate such that the light-emitting element is positioned in an opening of the frame member; and

entirely sealing the light-emitting element and the frame member on the upper surface of the substrate with a light-transmitting resin.

19. The lighting device according to claim 14 , wherein the light-shielding member is inside the white-colored resin of the frame member.

20. The lighting device according to claim 14 , wherein the light-shielding member comprises a black-colored resin.
