Patent ID: 8476661

Claim:
A light emitting element, comprising: a light emitting diode (LED) chip having an upper surface; and a wavelength-converting layer having a top surface, an opposing bottom surface, and sidewalls extending from the top surface to the bottom surface, the bottom surface being disposed on the upper surface of the LED chip, the wavelength-converting layer configured to convert a wavelength of light emitted from the LED chip, wherein, a total area of the bottom surface is less than or equal to a total area of the upper surface, a total area of a first horizontal cross-section of the wavelength-converting layer, taken between the top and bottom surfaces, is greater than a total area of the upper surface of the LED chip, and the sidewalls comprise protrusions having a rectangular vertical cross-section, or the sidewalls protrude outwardly so as to have a V-shaped vertical cross-section.
