[0040] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0041] Such as figure 1 Shown, a kind of automobile headlight reflector design method, comprises the following steps:
[0042] (1) The car light is a complete lighting system. In order to meet a certain illuminance value, the traditional vehicle uses a parabola as a reflector, and the filament is located near the focus of the parabola. The design of the free-form surface lamp basically adopts this principle; Such as image 3 As shown, the basic reflective surface is established in the X, Y, Z three-dimensional coordinate system. The basic reflective surface is a paraboloid, and the focus of the paraboloid is f. According to the principle of the paraboloid, since the light emitted from the focus is emitted in parallel through the paraboloid, The position of the light source is set at coordinates (0, 0, 15mm);
[0043](2) According to the light dist...
