    • A vehicle lamp includes a plurality of light sources, and a light guide plate configured to emit light to the front side of the lamp from a second surface facing a first surface by internally reflecting light, which is emitted from the respective light sources, by a plurality of reflective elements formed on the first surface after causing the light to enter the light guide plate from a rear end face of the light guide plate. The light guide plate is curved to the first surface and gradually becomes thinner toward the front side. The reflective elements are disposed at a predetermined interval in a longitudinal direction and extend in a direction crossing the longitudinal direction.
    • 车灯包括多个光源,以及导光板,被配置为通过内部反射从各个光源射出的光,从相对于光源射出的光从与第一表面相对的第二表面向灯的前侧发光 多个反射元件在使导光板从导光板的后端面进入导光板之后,形成在第一面上。 导光板向第一表面弯曲并朝向前侧逐渐变薄。 反射元件沿纵向方向以预定间隔设置并且在与纵向相交的方向上延伸。

    • A vehicular lamp including, within its lamp chamber, a reflector 14, a led 20 disposed behind the reflector 14 and a mushroom-shaped light guide 30 that extends coaxially with the led 20 and guides light emitted from the led 20 to the reflector 14. The light guide 30 has an umbrella portion 40 at its front end and a plane of incidence 33, which guides light from the led 20 into the light guide 30, at its rear end. The umbrella portion 40 has a first light emitting surface 42 for emitting light guided into the light guide 30 in the forward direction, reflection surfaces 44 and 46 for internally reflecting the guided light in the rearward direction and radially outward direction, and a second light emitting surface 48 for emitting the internally reflected light toward the reflector 14.
    • 一种车灯,在其灯室内包括反射器14,设置在反射器14后面的LED20和与LED20同轴地延伸的蘑菇状导光体30,并将从LED 20发射的光引导到反射器14。 光导30在其前端具有伞形部分40,并且在其后端具有将来自LED20的光引导到光导30中的入射面33。 伞部40具有第一发光面42,用于向前方向射出导向光导30的光,反射面44,46,用于向后方向和径向向外方向反射引导光;第二发光面42, 表面48用于向反射器14发射内部反射光。

    • A vehicular lamp includes: a light-emitting element arranged face forward; and a translucent member arranged to cover the light-emitting element from its front side. The member has a horizontally oblong shape in a front view, and includes: a direct light control portion located near the optical axis and directly emitting light forward from a front surface of the member; reflected light control portions located both sides of the direct light control portion and internally reflecting the entered light on a rear surface of the member to form substantially parallel light directed forward and emitting the light forward from the front surface; and a curved-surface light incident area formed on the rear surface to allow light from the light-emitting element to enter as substantially parallel light with respect to a cross section parallel to the axis and a longitudinal direction of the member in the direction perpendicular to the cross section.
    • 一种车灯包括:向前排列的发光元件; 以及设置成从其前侧覆盖发光元件的半透明构件。 该构件在前视图中具有水平长方形形状,并且包括:位于光轴附近并直接从构件的前表面向前发光的直射光控制部; 反射光控制部分位于直接光控制部分的两侧,并将入射的光内部反射到该部件的后表面上,以形成朝向前方的大致平行的光并从前表面向前发射光; 以及形成在后表面上的曲面光入射区域,以允许来自发光元件的光线相对于平行于该轴线的横截面和沿垂直于该方向的方向的该纵向方向进入基本上平行的光 横截面。
