Claim of US Patent No. 10,211,374

1. A device comprising:a light emitting device comprising a substrate and a semiconductor structure comprising a light emitting layer;
a first reflective layer contacting and conforming to side surfaces of the substrate and semiconductor structure to laterally surround the light emitting device;
a wavelength converting element disposed over the light emitting device, the wavelength converting element having a top surface and sidewalls, the top surface of the wavelength converting element being higher than the top surface of the first reflective layer; and
a second reflective layer disposed adjacent a first sidewall of the wavelength converting element, but not over the top surface or a second sidewall of the wavelength converting element, such that the majority of light exits the top surface of the wavelength converting element and a majority of light impinging on the second reflective layer is reflected back into the wavelength converting element.
