==VEHICLE LIGHT-EMITTING DEVICE AND VEHICLE LIGHTING DEVICE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18467677 titled 'VEHICLE LIGHT-EMITTING DEVICE AND VEHICLE LIGHTING DEVICE

==Simplified Explanation==

The vehicle light-emitting device described in the abstract includes a light-emitting element with a peak emission wavelength between 400 nm and 510 nm, as well as a fluorescent member with two phosphors that emit light in different wavelength ranges when excited by the light emitted by the light-emitting element. The device emits light within a specific region in a CIE1931 chromaticity diagram.
