Light emitting device including a filter and a protective layer
A method according to embodiments of the invention includes providing a plurality of LEDs attached to a mount. A filter is attached to at least one of the plurality of LEDs. A protective layer is formed over the filter. A reflective layer is formed over the mount. A portion of the reflective layer disposed over the protective layer is removed.
1. A structure, comprising:
a plurality of LEDs attached to a mount;
a plurality of wavelength converting layers disposed over the LEDs;
a plurality of transparent layers disposed over the wavelength converting layers;
a reflective material disposed in areas between neighboring LEDs; and
a top surface of the structure comprising the transparent layers over the LEDs and the reflective material over the areas between the neighboring LEDs, the top surface of the structure being substantially planar.
2. The structure of claim 1 , wherein top surfaces of the transparent layers are roughened, textured, or patterned.
3. The structure of claim 1 , wherein the reflective material is in direct contact with side surfaces of the neighboring LEDs.
4. The structure of claim 1 , wherein each wavelength converting layer and each transparent layer have a substantially same width as a top surface of each LED.
5. The structure of claim 4 , wherein the reflective material is in direct contact with sidewalls of neighboring transparent layers disposed over the neighboring LEDs.
6. The structure of claim 4 , wherein the reflective material is in direct contact with sidewall of neighboring transparent layers disposed over the neighboring LEDs.
7. The structure of claim 4 , wherein top surfaces of the transparent layers are roughened, textured, or patterned.
8. The structure of claim 4 , wherein the reflective material is in direct contact with side surfaces of the neighboring LEDs.
9. The structure of claim 4 , wherein the reflective material is in direct contact with the mount.
10. The structure of claim 1 , wherein the reflective material is in direct contact with portions of the wavelength converting layers and the mount.
