Title
(EN) MICRO VEHICLE LAMP MODULE AND REFLECTING STRUCTURE
(FR) MICRO-MODULE DE LAMPE DE VÉHICULE ET STRUCTURE RÉFLÉCHISSANTE

Abstract
(EN)
A vehicle lamp module and a reflecting structure thereof. The vehicle lamp module comprises a reflector (2) and a lens (3), the front end of the reflector (2) being provided with a reflector interconnecting piece (21), and the rear end of the lends (3) being provided with a lens interconnecting piece (31). The reflector interconnecting piece (21) is cooperatively connected with the lens interconnecting piece (31) such that the reflector (2) is relatively fixed with the lens (3). The reflector (2) comprises a first reflecting surface (2a), a second reflecting surface (2b) and a third reflecting surface (2c). The vehicle lamp module further comprises a fourth reflecting surface (2d). The first reflecting surface (2a) is used for forming a central area (A) light shape, the second reflecting surface (2b) is used for forming a widened area (B) light shape, the third reflecting surface (2c) and the fourth reflecting surface (2d) are used for together forming a III area (C) light shape. The fourth reflecting surface (2d) and the reflector (2) form an integral structure. The reflecting structure comprises a reflector (2) and a cut-off line structure (8). The cut-off line structure (8) is used for forming a cutoff line (E) of the light shape; the cut-off line structure (8) and the reflector (2) form an integral structure. High optical system accuracy is thus obtained.

L'invention concerne un module de lampe de véhicule et une structure réfléchissante associée. Le module de lampe de véhicule comprend un réflecteur (2) et une lentille (3), l'extrémité avant du réflecteur (2) étant pourvue d'une pièce de liaison de réflecteur (21), et l'extrémité arrière de la lentille (3) étant pourvue d'une pièce de liaison de lentille (31). La pièce de liaison de réflecteur (21) est reliée en coopération avec la pièce de liaison de lentille (31) de telle sorte que le réflecteur (2) est relativement fixé à la lentille (3). Le réflecteur (2) comprend une première surface réfléchissante (2a), une deuxième surface réfléchissante (2b) et une troisième surface réfléchissante (2c). Le module de lampe de véhicule comprend en outre une quatrième surface réfléchissante (2d). La première surface réfléchissante (2a) sert à former une forme de lumière de zone centrale (A), la deuxième surface réfléchissante (2b) sert à former une forme de lumière de zone élargie (B), et la troisième surface réfléchissante (2c) et la quatrième surface réfléchissante (2d) servent à former ensemble une forme de lumière de zone III (C). La quatrième surface réfléchissante (2d) et le réflecteur (2) forment une structure solidaire. La structure réfléchissante comprend un réflecteur (2) et une structure de ligne de coupure (8). La structure de ligne de coupure (8) sert à former une ligne de coupure (E) de la forme de la lumière ; la structure de ligne de coupure (8) et le réflecteur (2) forment une structure solidaire. Une haute précision du système optique est ainsi obtenue.
