Light-emitting diode (LED) headlamp for motorcycle

Abstract

The invention discloses a light-emitting diode (LED) headlamp for a motorcycle. According to the LED headlamp, a middle bulge, a left bulge and a right bulge are arranged on the bottom surface of a passing light inner lens of a passing light source assembly; the surface of the middle bulge is provided with an arc surface which has the curvature radius of 0-110mm; the middle bulge has a luminous angle within the range from -0.9 degree to 0.9 degree; one surface of the left bulge is an arc surface, and the other surface of the left bulge is a vertical plane; the arc surface has the curvature radius of 214-517mm; the left bulge has a luminous angle within the range of -1 degree to -0.9 degree; one surface of the right bulge is an arc surface, and the other surface of the right bulge is a vertical plane; the arc surface has the curvature radius of 214-618mm; and the right bulge has a luminous angle of 0.9-2.0 degrees. After light rays pass through the passing light inner lens, a passing light type with an obvious dividing line can be obtained, the large-angle light rays can be effectively utilized, and the utilization rate of luminous flux is effectively improved, so that the light irradiation distance and width are obviously increased, and a blind area is prevented from occurring in a passing light irradiation area.
一种摩托车LED前照灯,近光光源组件的近光内透镜底面设有中间凸起、左凸起和右凸起;中间凸起表面呈弧面,其曲率半径为0~110mm,中间凸起的发光角度为-0.9°~0.9°;左凸起的其中一面为弧面,另一面为竖直面,弧面的曲率半径为214~517mm,左凸起的发光角度为-1°~-0.9°;右凸起的其中一面为弧面,另一面为竖直面,弧面的曲率半径为214~618mm,右凸起的发光角度为0.9°~2.0°。本发明光线通过近光内透镜后,可得到具有明显明暗截止线的近光光型,能够有效的将大角度的光线利用起来,光通量的利用率得到有效提高,使灯光的照射距离、宽度明显增大,同时防止近光照射区域出现盲区。
