Abstract:
(EN) A high-efficiency vehicle light-emitting diode (LED) headlight and a light distribution method. The headlight comprises a parabolic reflective bowl (2), and a group of semi-elliptical reflective bowls (3) that evenly surrounds the parabolic reflective bowl (2) by using the same as the center; an LED (1) is arranged at the focal point of the parabolic reflective bowl (2), and LEDs (1) are arranged at first focal points of the semi-elliptical reflective bowls (3); second focal points of the semi-elliptical reflective bowls (3) coincide at a point and are located on the symmetric central axis of the parabolic reflective bowl (2), while a light blocking plate (4) is arranged at the second focal points of the semi-elliptical reflective bowls (3), the light blocking plate (4) being placed at the rear focal point of an aspheric lens (5).
(FR) L'invention concerne un phare de véhicule à diode électroluminescente (DEL) à haut rendement et un procédé de distribution de lumière. Le phare comprend un bol réfléchissant parabolique (2) et un groupe de bols réfléchissants semi-elliptiques (3) qui entoure uniformément le bol réfléchissant parabolique (2) en utilisant ce dernier comme centre ; une DEL (1) est agencée au niveau du foyer du bol réfléchissant parabolique (2) et des DEL (1) sont agencées au niveau de premiers foyers des bols réfléchissants semi-elliptiques (3) ; des seconds foyers des bols réfléchissants semi-elliptiques (3) coïncident en un point et sont situés sur l'axe central symétrique du bol réfléchissant parabolique (2), tandis qu'une plaque de blocage de lumière (4) est agencée au niveau des seconds foyers des bols réfléchissants semi-elliptiques (3), la plaque de blocage de lumière (4) étant placée au niveau du foyer arrière d'une lentille asphérique (5).
(ZH) 高效汽车LED前照灯及配光方法。前照灯组成包括一个抛物线型反光碗(2),以所述的抛物线型反光碗(2)为中心,均匀围绕着一组半椭圆反光碗(3),抛物线型反光碗(2)的焦点处设置有LED(1),半椭圆反光碗(3)的第一焦点处设置有LED(1),所有半椭圆反光碗(3)的第二焦点重合在一点并处于抛物线型反光碗(2)的对称中轴线上,半椭圆反光碗(3)的第二焦点处设置有挡光板(4),所述的挡光板(4)放在非球面透镜(5)的后焦点处。
