In this lamp module, the light source is disposed at the first focal point of the reflector a, the light shielding portion c is disposed at the second focal point of the reflector a, and the lens focal point is disposed at the second focal point of the reflector a, so that the relative positions of the optical elements in the entire lamp optical system are uniquely determined and are applicable only to one arrangement of the space inside the lamp.
With the development of vehicles and lamp technologies, the variety of lamp designs is limited by the space within the lamp, but since the relative positional relationship between the optical elements of the integrated optical system is uniquely determined, the desired light shape cannot be obtained if the relative position between the optical elements is changed again according to the space within the lamp. Therefore, the integrated optical system has low versatility, is not favorable for model arrangement and/or cannot meet space layout, and usually needs to meet structural requirements by sacrificing the vehicle lamp model requirements.
In addition, because functions such as head-light, fog lamp have irradiation angle requirement after the loading, so all need adjust luminance, current car light generally all adopts car light system overall adjustment for adjust the space demand big, optical system quality is great, and required support intensity and governing system also need be higher, and have the risk of vibration back illumination direction skew.
