    摘要： A stack unit is provided for a signal indicator lamp including a plurality of such stack units stacked in a stacking direction. The stack unit includes an outer member, an inner member provided in a first internal space of the outer member, a support portion provided on the outer member, a board held in a second internal space of the inner member, and a first connector and a second connector for external electrical connection. The support portion supports the inner member so that the inner member is rotatable relative to the outer member about a rotation axis extending in the stacking direction and immovable relative to the outer member in the stacking direction. The first connector is provided at one end of the board with respect to the stacking direction, and the second connector is provided at an other end of the board.

    摘要： A lens component disperses light from a source having a distribution characteristic in which luminosity becomes smaller according to distance from the optical axis. The component includes an incidence portion at a source position struck by light from the source and guiding portions branching from the incidence portion and extending radially from the source position. Each guiding portion includes a basal end portion joined to the incidence portion, emission end portion emitting light away from the source, and reflection surface guiding light that struck the basal end portion while performing internal reflection. The incidence portion and guiding portions form a light distribution structure arranged so that a ratio of luminosity in a direction making a predetermined angle with the optical axis with respect to luminosity in the axial direction in light emitted from the structure is larger than a corresponding ratio in the source's distribution characteristic.
