A light emitting device has a resonant cavity LED (RCLED) ( 1 ) within encapsulation ( 24 ). The encapsulation has a convex spherical surface ( 26 ) forming a lens for emitted light. The diode's cavity ( 14, 15, 16 ) is of a length to provide detuning of 20 nm for an emission wavelength of 650 nm. A relatively flat thermal response is achieved.
