PROBLEM TO BE SOLVED: To cause a light-emitting component for vehicle including a curved plate-shaped transmission body to uniformly emit light.SOLUTION: A light-emitting ornament 1 installed in a vehicle includes as a light-emitting region 10a: a light source unit 20 which has a lamp 21 being a point-like light source and a planar light guide body 22 having an emission surface 22a emitting the light from the lamp 21 and emits the light toward the front side of the light-emitting region 10a; and a curved plate-shaped ornament 10 which makes the light emitted from the light source unit 20 transmit therethrough at the front position of the light source unit 20. The ornament 10 includes a portion having a different interval from the light guide body 22. The light-emitting ornament 1 further includes a surface luminance adjustment unit 22d which adjusts the luminance of the outer surface of the ornament 10 according to the magnitude of the interval between the ornament 10 and the light guide body 22.SELECTED DRAWING: Figure 2
【課題】曲板形状の透過体を備える車両用発光部品を均一に発光させる。【解決手段】車両に設置される発光オーナメント1は、点状光源であるランプ21とランプ21からの光を出射する出射面22aを備えた平板状の導光体22とを有して発光領域10aの前方に向けて光を照射する光源ユニット20と、光源ユニット20の前方位置にて光源ユニット20から出射された光を透過させる曲板状のオーナメント10と、を発光領域10aとして備える。オーナメント10は、導光体22との間隔が異なる部位を有する。そして、発光オーナメント1は、オーナメント10と導光体22との間隔の大きさに応じてオーナメントの10外表面の輝度を調整する表面輝度調整部22dを更に有する。【選択図】図2
