| 发明名称 | Vehicle lamp | ||
| 摘要 | A vehicle lamp includes a semiconductor light source disposed on an optical axis of the vehicle lamp, a reflector having a plurality of reflective surfaces radially divided about the optical axis and boundary portions formed between two of the reflective surfaces adjacent to each other, and a lens cap that covers the front side of the light source. The lens cap includes a side lens portion that projects laterally emitted light from the light source toward the reflector. The laterally emitted light makes an angle with the optical axis that is at least a predetermined angle. The side lens portion is divided into at least two lens elements in a circumferential direction around the optical axis, and refracts the laterally emitted light so that the laterally emitted light avoids the boundary portions. | ||

| 主权项 | 1. A vehicle lamp comprising: a semiconductor light source disposed on an optical axis of the vehicle lamp; a reflector comprising a plurality of reflective surfaces radially divided about the optical axis and boundary portions formed between two of the reflective surfaces adjacent to each other; and a lens cap that covers the front side of the light source, wherein the lens cap comprises a side lens portion that projects laterally emitted light from the light source toward the reflector, wherein the laterally emitted light makes an angle with the optical axis that is at least a predetermined angle, and wherein the side lens portion is divided into at least two lens elements in a circumferential direction around the optical axis, and refracts the laterally emitted light so that the laterally emitted light avoids the boundary portions. | ||
