Abstract
The light emitting device has a light emitting element 101, and translucent material 102 that passes incident light from the light emitting element 101 and emits that light to the outside. The sides of the translucent material 102 perimeter are inclined surfaces 107 that become wider from the upper surface to the lower surface. The area of the lower surface of the translucent material 102 is formed larger than the area of the upper surface of the light emitting element 101. The lower surface of the translucent material 102 and the upper surface of the light emitting element 101 are joined together, and the part of the lower surface of the translucent material 102 that is not joined with the light emitting element 101 and the inclined surfaces 101 are covered by light reflecting resin 103.
Claims20
A light emitting device comprising:
- a light emitting element with an upper surface that is a light emitting surface;
- a translucent material with an upper surface and a lower surface, where light from the light emitting element is incident on the lower surface and light is emitted to an area outside the light emitting device through the upper surface;
- and
- a light reflecting resin that covers at least one part of the translucent material,
- wherein the translucent material includes a covered region that is covered with the reflecting resin and a non-covered region that is exposed to the area outside the light emitting device, wherein an area of the non-covered region on the upper surface of the translucent material is smaller than an area of the lower surface of the translucent material,
- wherein the area of the lower surface of the translucent material is larger than an area of the upper surface of the light emitting element,
- wherein the lower surface of the translucent material is joined to the upper surface of the light emitting element, and
- wherein a region of the lower surface of the translucent material that is not joined to the upper surface of the light emitting element is covered with the light reflecting resin.
