Abstract:
A light emitting device having first, second and third dimensions that are orthogonal may include a light emitting semiconductor device configured to emit light via a first surface in a plane formed by the first and second dimensions. The light emitting device may further include a wavelength converting structure disposed on the first surface of the light emitting semiconductor device, the wavelength converting structure extending beyond the light emitting semiconductor device in the first dimension and the light emitting semiconductor device extending beyond the wavelength converting structure in the second dimension. The light emitting device may further include one or more optical extraction features in at least one gap formed by the wavelength converting structure extending beyond the light emitting semiconductor structure in the first dimension and/or formed by the light emitting semiconductor structure extending beyond the wavelength converting structure in the second dimension.
