Light emitting device
A light emitting device includes a substrate, a plurality of light sources, a light reflecting member and a resin member. The substrate defines a through hole. The light reflecting member includes a wall part having a first surface and a second surface. The first surface defines a plurality of surrounding parts respectively surrounding each of the light sources individually or two or more of the light sources in groups. The second surface defines a hollow part. The resin member is disposed inside the hollow part. The hollow part defines a first opening on a substrate side of the wall part. The through hole defines a second opening positioned inner than the first opening. The resin member is continuously in contact with the second surface and the upper surface of the substrate in a region between a peripheral edge of the second opening and a peripheral edge of the first opening.
1. A light emitting device comprising:
a substrate defining a through hole penetrating through the substrate in a thickness direction;
a plurality of light sources disposed on the substrate;
a light reflecting member disposed on the substrate and including a wall part having
a first surface defining a plurality of surrounding parts respectively surrounding each of the light sources individually or two or more of the light sources in groups, and
a second surface on an opposite side of the first surface and defining a hollow part; and
a resin member disposed inside the hollow part, wherein
the hollow part defines a first opening on a substrate side of the wall part,
the through hole defines a second opening at an upper surface of the substrate, the second opening being positioned inner than the first opening in the top view, and
the resin member is continuously in contact with the second surface of the wall part defining the hollow part and the upper surface of the substrate in a region between a peripheral edge of the second opening and a peripheral edge of the first opening.
2. The light emitting device according to claim 1 , wherein
the through hole is connected to the hollow part.
3. The light emitting device according to claim 1 , wherein
the resin member extends along the upper surface of the substrate from the peripheral edge of the second opening in the top view.
4. The light emitting device according to claim 1 , wherein
the light reflecting member includes a bottom surface part disposed on the substrate.
5. The light emitting device according to claim 1 , wherein
the resin member is configured to reflect light emitted from the light sources.
6. The light emitting device according to claim 1 , wherein
the resin member is configured to absorb light emitted from the light sources.
7. The light emitting device according to claim 1 , further comprising
a member disposed above the light reflecting member, wherein
a top part of the wall part of the light reflecting member is in contact with the member disposed above the light reflecting member.
8. The light emitting device according to claim 1 , wherein
the light sources are arranged at intervals in a range of 5 mm to 25 mm.
9. The light emitting device according to claim 1 , wherein
the surrounding parts of the wall part are arranged at intervals in a range of 5 mm to 25 mm.
