PROBLEM TO BE SOLVED: To provide a decorative lighting device showing a superior beautiful appearance, enabling a bright lighting to be attained under a low cost.SOLUTION: A vehicular decorative lighting device 10 comprises an outer lens 20 for guiding radiation light of LED in its extending direction and a housing 30 covering a rear surface side of the outer lens 20. The outer lens 20 comprises a rectangular column-like surface protrusion part 25 including a surface 25a acting as a light emission surface and both side surfaces 25b, 25c acting as light reflection surfaces; a rectangular column-like rear protrusion part 26 including a rear surface 26a acting as a light reflection surface and both side surface 26b, 26c; a long-length angle-shaped first connection part 27 having one end part 27a connected to each of the side surfaces 25b, 26b; and a long-length angle-shaped second connecting part 28 having one end part 28a connected to each of the side surfaces 25c, 26c. The housing 30 is attached and fixed to the other end portions 27b, 28b of each of the connecting parts 27, 28 to cover it in a liquid-sealed state. A width t1 of each of both side surfaces 25b, 25c at a vertical sectional view of the outer lens 20 is larger than a width t2 of the surface 25a.SELECTED DRAWING: Figure 2
【課題】美観に優れた明るい照明が可能で低コストな加飾照明装置を提供する。【解決手段】車両用加飾照明装置10は、LEDの放射光を延在方向に導光するアウタレンズ20と、アウタレンズ20の裏面側を覆設するハウジング30とを備える。アウタレンズ20は、光出射面である表面25aと光反射面として作用する両側面25b,25cとを有する四角柱状の表側突出部25と、光反射面として作用する裏面26aおよび両側面26b,26cを有する四角柱状の裏側突出部26と、各側面25b,26bに一端部27aが接続された長尺アングル状の第1接続部27と、各側面25c,26cに一端部28aが接続された長尺アングル状の第2接続部28とを備える。ハウジング30は、各接続部27,28の他端部27b,28bに取付固定されて液密状態に覆う。アウタレンズ20の縦断面にて、両側面25b,25cの幅t1は表面25aの幅t2よりも大きい。【選択図】 図2
