Abstract:
(EN) A projection lens (20) comprises a first incident face (22a) which corresponds to a first focal point (F1) and a second incident face (22b) which corresponds to a second focal point (F2). The light output from a first light source (30) is incident upon the first incident face (22a) and passes through the projection lens (20). A second light source (70), which is turned on when the first light source (30) is switched off, is provided at a position, between the first light source (30) and the projection lens (20), through which light output from the first light source (30) reaching the first incident face (22a) does not pass. The light output from the second light source (70) is incident upon the second incident face (22b) and passes through the projection lens (20).
(FR) Une lentille de projection (20) comprend une première face incidente (22a) qui correspond à un premier point focal (F1) et une seconde face incidente (22b) qui correspond à un second point focal (F2). La sortie de lumière provenant d'une première source de lumière (30) est incidente sur la première face incidente (22a) et passe à travers la lentille de projection (20). Une seconde source de lumière (70), qui est allumée lorsque la première source de lumière (30) est éteinte, est prévue à une position, entre la première source de lumière (30) et la lentille de projection (20), à travers laquelle la lumière délivrée en sortie par la première source de lumière (30) atteignant la première face incidente (22a) ne passe pas. La sortie de lumière depuis la seconde source de lumière (70) est incidente sur la seconde face incidente (22b) et passe à travers la lentille de projection (20).
(JA)  投射レンズ20は、第1焦点F1に対応する第1入射面22a、および第2焦点F2に対応する第2入射面22bを有する。第1光源30から出射された光は、第1入射面22aに入射して投射レンズ20を通過する。第1光源30の消灯時に点灯される第2光源70は、第1光源30と投射レンズ20の間における、第1光源30から出射されて第1入射面22aに至る光が通過しない位置に配置される。第2光源70から出射された光は、第2入射面22bに入射して投射レンズ20を通過する。
