    • There is provided headphones that include a pair of left and right earcups, an audio signal processing unit contained in the earcups, a headband connecting the left and right earcups respectively through a hanger, and a cord to supply a signal to the audio signal processing unit. In the headphones, a connection portion between the hanger and the headband is configured as an extension and contraction unit having a multistage structure including a small-diameter hollow member able to be taken in and out of a large-diameter hollow member, a part of the cord contained in the extension and contraction unit is spirally wound so as to be extended and contracted, nodes are placed respectively between the headband and the extension and contraction unit and between the hanger and the extension and contraction unit, and the respective nodes have a through-hole allowing penetration of the cord.

    • Lamp piece units in a parabolic pillar type capable of forming a luminous intensity distribution pattern prolonged sideways are formed as side irradiating lamp piece units. Thereby, a portion of diffused and reflected light from reflectors of the respective side irradiating lamp piece units is prevented from being blocked by other lamp piece constituting members, even when a surface shape of a vehicular headlamp is flexed to the rear side. Further, although the respective side irradiating lamp piece units are constituted by the lamp piece units of the parabolic pillar type having an angular outer shape as a whole, a large depth space for arranging the units is dispensed with.
    • 能够形成横向延伸的发光强度分布图案的抛物柱型的灯片单元被形成为侧面照射灯片单元。 因此,即使当车辆用前照灯的表面形状向后方弯曲时,也能够防止来自各侧面照明灯具单元的反射器的漫反射光的一部分被其他灯具构成构件阻挡。 此外,尽管各侧照射灯片单元由具有整体角形外形的抛物柱型灯件单元构成,但是省略了用于布置该单元的大的深度空间。

    • A vehicular headlamp including a lighting fixture unit that emits white light in upper beam irradiation and emits infrared light in lower beam irradiation. The lighting fixture unit includes: a light source part including a first semiconductor light-emitting element as a white light source and a second semiconductor light-emitting element as an infrared light source; an optical member for irradiating in forward direction the light from each semiconductor light-emitting element; and an optical axis adjusting unit for changing in a vertical plane the direction of optical axis related to the first and second semiconductor light-emitting elements.
    • 一种车辆前照灯,包括照明装置单元,其在上光束照射中发射白光并在较低光束照射中发射红外光。 照明器具包括:包括作为白光源的第一半导体发光元件和作为红外光源的第二半导体发光元件的光源部; 光学构件,用于向前照射来自每个半导体发光元件的光; 以及光轴调整单元,用于在垂直平面中改变与第一和第二半导体发光元件相关的光轴的方向。
