Abstract

A light emitting component includes a light emitting unit, a molding compound and a wavelength converting layer. The light emitting unit has a forward light emitting surface. The molding compound covers the light emitting unit. The wavelength converting layer is disposed above the molding compound. The wavelength converting layer has a first surface and a second surface opposite to the first surface, wherein the first surface is located between the forward light emitting surface and the second surface, and at least one of the first and second surfaces is non-planar.

Claims

1. A light emitting component comprising:

a light emitting unit having a forward light emitting surface;

a molding compound covering the light emitting unit; and

a wavelength converting layer disposed above the molding compound, the wavelength converting layer having a first surface and a second surface opposite to the first surface, the first surface being located between the forward light emitting surface and the second surface, at least one of the first and second surfaces being non-planar.

2. The light emitting component of claim 1, wherein the first surface contacts the molding compound and is non-planar.

3. The light emitting component of claim 2, wherein the second surface is non-planar.

4. The light emitting component of claim 2, further comprising a light transmissible member disposed on the wavelength converting layer, wherein the second surface contacts the light transmissible member and is planar.

5. The light emitting component of claim 1, further comprising a light transmissible member disposed between the molding compound and the wavelength converting layer, wherein the first surface contacts the light transmissible member and is planar, and the second surface is non-planar.

6. The light emitting component of claim 1, wherein the wavelength converting layer is capable of deforming when a mechanical force is exerted on the wavelength converting layer.

7. The light emitting component of claim 1, further comprising a reflective layer disposed on a side light emitting surface of the light emitting unit around the forward light emitting surface.

8. The light emitting component of claim 7, wherein a vertical height of the reflective layer is larger than or equal to a vertical height of the side light emitting surface of the light emitting unite.

9. The light emitting component of claim 7, wherein a side surface of the reflective layer and a side surface of the wavelength converting layer are coplanar.

10. The light emitting component of claim 7, wherein a material of the reflective layer comprises a polymer material, a metal oxide material, a metal material or a combination thereof.
