A light emitting diode is provided having a LED layer configured to emit pump light having a pump light wavelength from a light emitting surface, the LED layer comprising a plurality of Group III-nitride layers. A container layer is provided on the light emitting surface of the LED layer, the container surface including an opening defining a container volume through the container layer to the light emitting surface of the LED layer. A colour converting layer is provided in the container volume, the colour converting Got layer configured to absorb pump light and emit converted light of a converted light wavelength longer than the pump light wavelength. A lens is provided on the container surface over the opening, the lens having a convex surface on an opposite side of the lens to the colour converting layer. A pump light reflector laminate provided over the convex surface of the lens the pump light reflector laminate having a stop-band configured to reflect the pump light centred on a first wavelength.
