Abstract

A method according to embodiments of the invention includes disposing a support layer on a surface of a wavelength converting ceramic wafer. The wavelength converting ceramic wafer and the support layer are diced to form wavelength converting members. A wavelength converting member is attached to a light emitting device. After attaching the wavelength converting member to the light emitting device, the support layer is removed.

Claims (6)

1 . A device comprising:

a light emitting device; and

a wavelength converting ceramic disposed in a path of light emitted by the light emitting device, wherein the wavelength converting ceramic has a thickness between 10 μm and 100 μm.

2 . The device of claim 1 wherein the wavelength converting ceramic has a thickness between 50 μm and 70 μm.

3 . The device of claim 1 further comprising a reflective material disposed around the light emitting device, wherein a top surface of the reflective material is at the same height as a top surface of the wavelength converting ceramic.

4 . The device of claim 1 wherein the wavelength converting ceramic is a preformed member, formed separately from the light emitting device.
