CPC F21S 41/285 (2018.01) [F21S 41/176 (2018.01); F21S 41/24 (2018.01); F21S 43/16 (2018.01)] | 19 Claims |
1. A lamp for a vehicle comprising:
at least one light source that generates a first light distribution including a first light component emitted in a first wavelength region;
a wavelength converter that converts the first light distribution into a second light distribution, wherein the wavelength converter includes a wavelength converting material that is excited by the first light component and generates a second light component emitted in a second wavelength region, such that the second light distribution includes the first light component and the second light component mixed at predetermined ratios; and
an optical module disposed in front of the wavelength converter to absorb at least a portion of the first light component emitted from the wavelength converter such that the lamp emits light substantially in the second wavelength region,
wherein the first light component is a blue light having a peak wavelength of about 400 nm to about 480 nm, and the second light component is a red light having a peak wavelength of about 620 nm to about 670 nm,
wherein a fraction of the first light component included in the second light distribution is about 18%, and
wherein a thickness of the wavelength converter is equal to or less than 400 μm.
