Abstract

A light emitting apparatus includes a mount substrate; two or more light emitting devices mounted on the mount substrate such that adjacent light emitting devices face each other at lateral surfaces thereof; a light transparent member positioned on upper surfaces of the light emitting devices, the light transparent member having a plate shape and being positioned to receive incident light emitted from the light emitting devices; and a covering member. In a plan view, the light transparent member is larger than each of the light emitting devices. The covering member contains a light reflective material and covers at least a lateral surface of the light transparent member.

Claims (23)

1. A light emitting apparatus comprising: a mount substrate;

two or more light emitting devices mounted on the mount substrate such that adjacent light emitting devices face each other at lateral surfaces thereof;

a light transparent member positioned on upper surfaces of the light emitting devices, the light transparent member having a plate shape and being positioned to receive incident light emitted from the light emitting devices; and

a covering member,

wherein, in a plan view, the light transparent member is larger than each of the light emitting devices, and

wherein the covering member contains a light reflective material and covers at least a lateral surface of the light transparent member.

2. The light emitting apparatus according to claim 1 , wherein, in a plan view, an entirety of each light emitting device is positioned within a periphery of the light transparent member.

3. The light emitting apparatus according to claim 1 , wherein, in a plan view, the light transparent member is larger than two of the light emitting devices.

4. The light emitting apparatus according to claim 1 , wherein each of the light emitting devices is attached to the light transparent member via an adhesive material.

5. The light emitting apparatus according to claim 1 , wherein the light transparent member is made of a resin, a glass, or a ceramic.

6. The light emitting apparatus according to claim 1 , wherein the light transparent member has an uneven surface.

7. The light emitting apparatus according to claim 1 , wherein the light transparent member comprises a plurality of wavelength conversion members adapted to convert a wavelength of at least a part of the light emitted from the light emitting devices to a different wavelength.

8. The light emitting apparatus according to claim 7 , wherein the plurality of wavelength conversion members are adapted to convert said at least a part of the light emitted from the light emitting devices into light in yellow to red ranges.

9. The light emitting apparatus according to claim 1 ,

wherein the light transparent member has a light emission surface and a light receiving surface, and

wherein an upper surface of the covering member is substantially coplanar with the light emission surface of the light transparent member.

10. The light emitting apparatus according to claim 1 ,

wherein the light transparent member has a light emission surface and a light receiving surface, and

wherein an upper surface of the covering member is retracted from the light emission surface of the light transparent member toward the light receiving surface of the light transparent member.

11. The light emitting apparatus according to claim 1 , wherein the covering member is black.

12. The light emitting apparatus according to claim 1 , further comprising a protection device.

13. The light emitting apparatus according to claim 1 , wherein the light emitting device is mounted on the mount substrate in a flip-chip manner.

14. The light emitting apparatus according to claim 1 , wherein the mount substrate is made of ceramic.
