| description | PROBLEM TO BE SOLVED: To restrict deterioration of outer appearance and irradiate light from an opening part formed at a vehicle body while improving a light utilization efficiency.SOLUTION: A vehicular lighting unit 1 is installed at a vehicle to irradiate light from an opening part H formed at a bumper B. The lighting unit comprises LED 4 arranged at a rear part of the opening part H and having a forward-directed optical axis Ax and an inner lens 5 arranged between LED 4 and the opening part H. The inner lens 5 is formed in such a way that a length L in a forward or rearward direction is longer than a thickness T of the opening part H along its width direction and at the same time the lens 5 has a lens main body part 51 arranged on the optical axis Ax of LED 4 while its front end surface 51b being near the opening part H, and a tapered part 521 extending out of the rear edge part of the lens main body part 51 so as to cover the side part of LED 4 in a thickness direction of the lens main body part 51.
【課題】見栄えの悪化を抑制するとともに光利用率を向上させつつ、車体に形成された開口部から光を照射させる。【解決手段】車両用灯具１は、車両に搭載され、バンパーＢに形成された開口部Ｈから光を照射させるものであり、開口部Ｈの後方に配置されるとともに、前方向きの光軸Ａｘを有するＬＥＤ４と、ＬＥＤ４と開口部Ｈとの間に配置されたインナーレンズ５とを備える。インナーレンズ５は、開口部Ｈの幅方向に沿った厚さＴよりも前後方向の長さＬが長尺に形成されるとともに、前端面５１ｂを開口部Ｈに近接させつつＬＥＤ４の光軸Ａｘ上に配置されたレンズ本体部５１と、レンズ本体部５１の厚さ方向におけるＬＥＤ４の側方を覆うように、レンズ本体部５１の後縁部から延出するテーパー部５２１とを有する。【選択図】図４ |
