DELINEATOR
To provide a delineator superior in visibility from a front part at a lighting portion.SOLUTION: A delineator includes a display housing main body 12, a cover lens portion 14 covering a front face side of the display housing main body 12, and an LED substrate 18 mounted inside of the cover lens portion 14. The LED substrate 18 is provided with a plurality of LEDs 16a, 16b, the cover lens portion 14 is provided with parabolic reflection portions 32a, 32b, the display housing main body 12 is provided with inclined reflection portions 28a, 28b, and further the cover lens portion 14 is provided with transmission lens portions 36a, 36b. The light from the plurality of LEDs 16a, 16b is reflected by the parabolic reflection portions (parabolic reflection faces) 32a, 32b to be parallel light, further reflected forward in a state of the parallel light by the inclined reflection portions (inclined reflection faces) 28a, 28b, and projected via the transmission lens portions 36a, 36b, thus a diffusion angle of the irradiation light is adjusted.SELECTED DRAWING: Figure 4
【課題】点灯部における前方からの視認性が良い視線誘導標を提供すること。【解決手段】表示ハウジング本体１２と、表示ハウジング本体１２の前面側を覆うカバーレンズ部１４と、カバーレンズ部１４の内側に取り付けられたＬＥＤ基板１８とを備えた視線誘導標。ＬＥＤ基板１８には複数のＬＥＤ１６ａ，１６ｂが実装され、カバーレンズ部１４には放物線状反射部３２ａ，３２ｂが設けられ、表示ハウジング本体１２には傾斜反射部２８ａ，２８ｂが設けられ、またカバーレンズ部１４には透過レンズ部３６ａ，３６ｂが設けられている。複数のＬＥＤ１６ａ，１６ｂからの光は、放物線状反射部（放物線状反射面）３２ａ，３２ｂにより平行光となるように反射され、更に傾斜反射部（傾斜反射面）２８ａ，２８ｂより平行光の状態で前方に向けて反射され、透過レンズ部３６ａ，３６ｂを通して投射されることにより照射光の拡散角度が調整される。【選択図】図４
