Abstract
Official abstract text for this publication.
A vehicle lamp emits red light from a second light emitting area by lighting a tail/accessory lamp while emitting red light from a first light emitting area during a lighting of a tail lamp. Meanwhile, the vehicle lamp lights out the tail/accessory lamp while emitting orange light from the second light emitting area during a lighting (flickering) of a turn lamp.
First claim
Opening claim text (preview).
What is claimed is: 1 . A vehicle lamp comprising: a first light source that emits a first colored light; a second light source that emits a second colored light having the same color as the first colored light; a third light source that emits a third colored light having a different color from the first colored light; a first light emitting section including a first light emitting area that emits light using the first colored light; a second light emitting section including a second light emitting area that emits light using the second colored light or the third colored light; and a lighting controller that controls lighting of the first light source, the second light source and the third light source, wherein the lighting controller performs control so that the second light source is turned on while the first source is turned on and so that the second light source is turned off while the third light source is turned on. 2 . The vehicle lamp according to claim 1 , wherein the vehicle lamp is disposed at both corner sections of a rear end side of the vehicle, the first colored light and the second colored light are red light, and the third colored light is orange light, and the lighting controller performs control of flickering the third light source while the third light source is turned on. 3 . The vehicle lamp according to claim 2 , wherein the lighting controller performs control of strengthening emission of the first light source upon braking of the vehicle compared to the emission while the first light source is normally turned on. 4 . The vehicle lamp according to claim 1 , wherein an intermediate member that is disposed between the first light emitting section and the second light emitting section and that includes a shielding area which shields a space between the first light emitting area and the second light emitting area is provided. 5 . The vehicle lamp according to claim 4 , wherein the intermediate member has a reflector structure in which a surface facing the first light emitting section and a surface facing the second light emitting section are constituted by reflection surfaces. 6 . The vehicle lamp according to claim 4 , wherein the first light emitting area, the shielding area and the second light emitting area are disposed to be arranged concentrically. 7 . The vehicle lamp according to claim 4 , wherein the intermediate member is disposed on an inner side of the first light emitting section and the second light emitting section is disposed on an inner side of the intermediate member.
