ABSTRACT:
The device includes a blue light emitting region having a first light emitting part and a yellow light emitting region having a second light emitting part and a wavelength converting member arranged to absorb light from the second light emitting part and to convert the wavelength thereof to emit yellow light. The second light emitting part has a higher output than that of the first light emitting part. With this arrangement, output of the yellow light can be increased, so that the device can be used in an image reading apparatus with a high sensitivity.
