Claim of US Patent No. 10,334,686

1. A light emitting module for illuminating an object, the light emitting module comprising:a first light emitting element comprising a first light emitter and a first luminescent element, the first light emitting element configured to emit a first light having a color point of white light, the first light emitter configured to emit a first blue light that is at least partially converted by the first luminescent element to a light of another color, wherein the first light represents a combination of the at least partially converted first blue light and any unconverted first blue light;
a second light emitting element configured to emit a peak of second blue light, the peak of second blue light having a peak wavelength in a range from 440 nanometer to 470 nanometer and having a spectral width that is smaller than 70 nanometers, the spectral width being expressed as a full width half maximum value, and the peak of second blue light being combined with the first light to form crispy white light having a light emission spectrum having more blue light in the range from 440 nanometer to 470 nanometer than the white light, such that when the light emitting module illuminates the object, an effect of using brighteners in the object is realized.
