    • A rear wall portion is at least partially disposed rearward of an LED chip. The rear wall portion forwardly reflects a light irradiated from the LED chip. A circumferential wall portion forwardly extends from the rear wall portion and extends circumferentially about an axis extending in a back-and-forth direction. A protruding portion forwardly protrudes from the rear wall portion while being disposed radially inward of the circumferential wall portion. A rib portion extends in a radial direction of the circumferential wall portion and is connected to the protruding portion and the circumferential wall portion. A housing includes a board mount space in which the LED board is disposed. The board mount space includes a first space and a second space. The first space is produced inside the protruding portion. The second space is produced inside the rib portion and communicates with the first space.
    • 后壁部分至少部分地设置在LED芯片的后方。 后壁部分向前反射从LED芯片照射的光。 周壁部分从后壁部分向前延伸并围绕沿前后方向延伸的轴线周向延伸。 突出部分从后壁部向前突出,同时布置在周壁部的径向内侧。 肋部分沿周壁部分的径向延伸并连接到突出部分和周壁部分。 壳体包括其中设置LED板的板安装空间。 板安装空间包括第一空间和第二空间。 第一空间在突出部分内产生。 第二空间在肋部内产生并与第一空间连通。
