A light emitting module (), adapted to produce white output light having an emission peak in the wavelength range from 400 to 440 nm, comprises: ⋅—at least one first light emitting element () adapted to emit light having an emission peak in a first wavelength range from 440 to 460 nm; ⋅—at least one wavelength converting material () arranged to receive light emitted by said first light emitting element, and being capable of emitting light having an emission peak in the green to red wavelength range; and ⋅—at least one second light emitting element () adapted to emit light having an emission peak in a second wavelength range from 400 to 440 nm. The module according to the invention provides white light of acceptable color rendering with a 'crisp white' effect.
