ILLUMINATION DEVICE FOR MOTOR VEHICLE PROJECTION LAMP

To provide an improved illumination device.SOLUTION: An illumination device for a motor vehicle projection lamp for producing a light distribution (50) for dipped light. The light distribution (50) for dipped light has a uniform light distribution in a region (51) below an intersection HV up to at least -3° along a vertical line V-V. The illumination device includes: light emitting means (100) for emitting light; a restrictor (200) having a restriction edge (200a), the restrictor (200) including a first restriction portion (210) and a second restriction portion (220) which are connected by a connection portion (230); and a projection optics system (300) configured so as to image the light distribution (50) for dipped light in the direction of a main emission direction (X). The connection portion (230) has a deflection surface (240). The deflection surface (240) extends along a flat plane having a plane vector (A), in which the plane vector (A) forms a first angle (W1) of 1° to 3° with respect to a first axis (y) and forms a second angle (W2) of 1° to 3° with respect to the main emission direction (X).SELECTED DRAWING: Figure 3 【課題】改善された照明装置の提供。【解決手段】減光ライト用光分布（５０）の生成のための自動車投光器用照明装置。減光ライト用光分布（５０）は交点ＨＶの下方の領域（５１）に垂直線Ｖ－Ｖに沿って少なくとも－３°まで均一な光分布を有する。照明装置は、光を放射するための発光手段（１００）、絞りエッジ（２００ａ）を有する絞り（２００）、但し絞り（２００）は結合部分（２３０）によって結合されている第１絞り部分（２１０）及び第２絞り部分（２２０）を含む、及び、減光ライト用光分布（５０）を主放射方向（Ｘ）の方向において結像するよう構成された投影光学系（３００）、を含む。結合部分（２３０）は偏向面（２４０）を有し、偏向面（２４０）は面ベクトル（Ａ）を有する平坦な面に沿って延在し、面ベクトル（Ａ）は、第１軸（ｙ）に対し１°～３°の第１角（Ｗ１）を形成し、かつ、主放射方向（Ｘ）に対し１°～３°の第２角（Ｗ２）を形成する。【選択図】図３
