Reflection-type headlamp module, headlamp module, headlamp and vehicle
A reflection-type headlamp module, comprising a light source, a light-converging element, a reflecting element and a lens, wherein the light-converging element is suitable for converging light rays emitted by the light source and projecting the light rays; and the reflecting element is arranged on a light-emergent light path of the light-converging element, and is suitable for reflecting, to the lens, the light rays emitted by the light source and projecting the light rays via the lens to form an illuminating light pattern. The reflecting element of the headlamp module changes the propagation direction of light rays, so that the front and rear diameter of the module is greatly reduced. In addition, high-beam light and low-beam light can be switched quickly and noiselessly, preventing the influence of a high-beam light path and a low-beam light path on each other. Further disclosed are a headlamp and a vehicle using the headlamp.
1. A headlamp module, comprising a reflection-type headlamp module and a light shielding plate, the headlamp module being a high-beam and low-beam integrated headlamp module that achieves a low-beam function and a high-beam function, the reflection-type headlamp module, comprising:
a light source;
a light-converging element;
a reflecting element; and
a lens;
the light-converging element being suitable for converging the light rays emitted by the light source and projecting the light rays, wherein:
the reflecting element is arranged on an emergent light path of the light-converging element so as to be suitable for reflecting the light rays emitted by the light source to the lens;
the light is projected by the lens to form an illuminating light pattern;
the light source comprises a low-beam light source and a high-beam light source;
the light-converging element comprises a low-beam condensing element and a high-beam condensing element, wherein the low-beam condensing element is suitable for converging the light rays emitted by the low-beam light source and projecting the light rays;
the light shielding plate is arranged on a projection light path of the low-beam condensing element so as to perform light beam distribution on the light rays emitted by the low-beam light source;
the high-beam condensing element is suitable for converging the light rays emitted by the high-beam light source and projecting the light rays;
the reflecting element is a reflecting mirror arranged on projection light paths of the low-beam condensing element and the high-beam condensing element so as to reflect the light rays emitted by the low-beam light source and/or the high-beam light source to the lens, wherein the light is projected by the lens to form an illuminating light pattern;
the low-beam condensing element is a low-beam reflecting cup that is shaped like a curved surface with a first focus and a second focus, the high-beam condensing element is a high-beam reflecting cup, the high-beam reflecting cup is shaped like a curved surface with a first focus and a second focus;
the lens comprises a low-beam region and a high-beam region, wherein the low-beam region and the high-beam region have different foci;
the second focus of the low-beam reflecting cup and a focus of the low-beam region are symmetrically arranged relative to the reflecting surface of the reflecting element; and
the second focus of the high-beam reflecting cup and a focus of the high-beam region are symmetrically arranged relative to the reflecting surface of the reflecting element.
2. The headlamp module according to claim 1 , wherein the low-beam light source is located at the first focus of the low-beam reflecting cup, and the light shielding plate is located in a second focus region of the low-beam reflecting cup; and/or
the high-beam light source is located at the first focus of the high-beam reflecting cup.
