Abstract:
A light emitting device comprising:a light generator responsive to an excitation signal for emitting first light in a wavelength range having a first peak wavelength;a curved wavelength selective reflector that is spaced apart from the light generator by a predetermined distance, said wavelength selective reflector being substantially transmissive with respect to said first light that is propagating in a first direction away from said light generator, said wavelength selective reflector having a curved shape and being positioned to at least partially surround said light generator, said wavelength selective reflector being substantially reflective with respect to second light in a wavelength range having a second peak wavelength that is propagating in a second direction toward said light generator; anda wavelength converter fixed at a side of said wavelength selective reflector opposite to said light generator to receive said first light propagating from said wavelength selective reflector in said first direction, said wavelength converter being responsive to said first light to generate said second light having said second peak wavelength.
