本発明は、車両照明の技術分野に関し、特に、車ランプ光学素子に関する。 The present invention relates to the technical field of vehicle lighting, and more particularly to vehicle lamp optics.

車ランプの技術分野において、車ランプモジュールとは一般的に、プラスチック又はガラス材質のレンズ又はそれらに相当する構造を備えた部品を最終的な出光素子として、自動車の前照灯の照明に用いられる装置を指す。車ランプ光学素子は車ランプモジュールの重要な構成部分であり、光源から出射された光線は車ランプ光学素子を介して出射された後、所望の車ランプパータンを形成することができる。 In the technical field of car lamps, car lamp modules are generally used for the illumination of automobile headlights, with the final light output element being a lens made of plastic or glass or a component with an equivalent structure. Point to the device. The car lamp optical element is an important component of the car lamp module, and the light emitted from the light source can form a desired car lamp pattern after being emitted through the car lamp optical element.

従来技術の車ランプモジュールは、一次光学素子と二次光学素子を有し、所望のパータンを得るように、一次光学素子と二次光学素子に対して二次配光調整を行う必要があり、二次配光調整は、１つの光学素子のみを設けた一次配光調整よりも柔軟であり、これは、２つの光学素子の配光パラメータを調整することで、パータンを調整することができるからであり、調整可能な配光パラメータが多く、例えば、一次光学素子の入光面、出光面、二次光学素子の入光面または出光面を調整することができる。 The prior art car lamp module has a primary optical element and a secondary optical element, and secondary light distribution adjustments need to be made to the primary optical element and the secondary optical element to obtain a desired pattern, The secondary light distribution adjustment is more flexible than the primary light distribution adjustment with only one optical element, because the pattern can be adjusted by adjusting the light distribution parameters of the two optical elements. , and there are many adjustable light distribution parameters, for example, the light entrance surface and the light exit surface of the primary optical element, and the light entrance surface and the light exit surface of the secondary optical element can be adjusted.

２、集光器をロービーム光学素子として使用する場合、ロービームカットオフラインを形成するように、集光器の前方に遮光板を設ける必要があり、これは車ランプモジュールの構造が複雑になり、寸法が大きくなることをもたらす。
３、機能は単一で、ロービーム、ハイビーム、補助ロービームと補助ハイビームのうちの１つの機能しか実現できない。 The prior art has the following drawbacks.
1. In general, a concentrator with multiple concentrating structures is adopted as the primary optical element,
The concentrator extends substantially along the front-back direction, and the lens provided at the tip of the concentrator is used as the secondary optical element, thus increasing the overall size of the lamp module and occupying space. result in more In addition, it is necessary to ensure the accuracy of the relative position between the two optical elements, and high demands are placed on assembly accuracy.
2. When the concentrator is used as a low-beam optical element, it is necessary to install a shading plate in front of the concentrator so as to form a low-beam cutoff line, which complicates the structure of the car lamp module and increases the size. causes the to grow.
3. The function is single, and only one of low beam, high beam, auxiliary low beam and auxiliary high beam can be realized.
