Abstract
Official abstract text for this publication.
A vehicular apparatus includes: a housing that is configured to be attached to a vehicle; and a first light source and a second light source that are provided in the housing to emit light having main wavelengths in mutually different wavelength ranges. The first light source emits light having a main wavelength in 490 nm-498 nm while the vehicle is being automatically driven.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicular apparatus comprising: a housing that is configured to be attached to a vehicle; and first and second lamp units that are provided in the housing and include first and second light sources respectively, that emit light having main wavelengths in mutually different wavelength ranges, wherein the first lamp unit is a lamp unit for alerting that the vehicle is being automatically driven when the vehicle is being automatically driven and emits light having a main wavelength in 490 nm-498 nm while the vehicle is being automatically driven, and wherein the second lamp unit is a turn signal lamp, a light emission region formed by light emitted from the first lamp unit and a light emission region formed by light emitted from the second lamp unit extend in the same direction. 2. The vehicular apparatus according to claim 1 , wherein the first light source and the second light source are mounted on the same substrate. 3. The vehicular apparatus according to claim 1 , wherein the first light source and the second light source are respectively mounted on first and second substrates provided to sandwich a heat dissipating member. 4. The vehicular apparatus according to claim 1 , wherein each of the first and second lamp units further includes first and second light conductors for controlling light from the first and second light sources, respectively. 5. The vehicular apparatus according to claim 4 , wherein the first light conductor and the second light conductor are arranged in alignment with each other. 6. The vehicular apparatus according to claim 5 , wherein the first light conductor and the second light conductor are arranged in alignment with each other in a horizontal direction, and light output from the second light conductor is transmitted through the first light conductor and output outside the vehicular apparatus, and the first light conductor and the second light conductor are formed such that light from the first light conductor and light from the second light conductor are not mixed. 7. The vehicular apparatus according to claim 4 , wherein the first light conductor and the second light conductor are adjacent to each other and are formed such that extensions from respective output surfaces are smoothly continuous with each other. 8. The vehicular apparatus according to claim 1 , wherein the first lamp unit and the second lamp unit further include a single light conductor for controlling light from the first light source and the second light source. 9. The vehicular apparatus according to claim 1 , wherein the light emission region formed by light emitted from the first lamp unit and the light emission region formed by the light emitted from the second lamp unit extend parallel to each other. 10. The vehicular apparatus according to claim 1 , wherein the light emission region formed by the light emitted from the first lamp unit and the light emission region formed by light emitted from the second lamp unit present a continuous linear or belt-like region.
