    摘要： Illumination device (10) for a vehicle headlamp, the illumination device comprising:
    - at least one light guide (100) comprising a light input section (110) and a light output section (120),
    - a light radiation body (200) comprising a free surface (220), wherein the light coupling out of the at least one light guide (100) can be coupled into the light radiation body (200) via the free surface (220),
    wherein light from at least one light source (50) can be radiated in front of the illumination device (10) via the light radiation body (200), wherein the illumination device (10) comprises a bundling device (300) configured to bundle and direct the light, which is coupled out from the light output section (120) of the at least one light guide (100), onto the free surface (220) of the light radiation body (200), so that light which is coupled out of the light output section (120) of the at least one light guide (100) and would not reach the free surface (220) due to a smaller width (W) of the free surface (220) compared to a diameter (D) of the light output section (120) of the at least one light guide (100), is deflected onto the free surface (220).

    摘要： The present invention discloses a general traffic headlight, including LEDs, a free-form surface convergence system located in front of the LEDs, a baffle located in front of the free-form surface convergence system, and a free-form surface outer lens located in front of the baffle. The free-form surface convergence system includes a collimator and a free-form surface; and all light rays are shot into the distance in parallel along an optical axis by the collimator, and the free-form surface at a light-emitting window is employed to design a light shape that meets the regulatory requirements. A structure of the headlight in this design is mainly composed of the collimator, the free-form surface, and the free-form surface outer lens. All the light rays are shot into the distance in parallel along the optical axis by the collimator, and the free-form surface at the light-emitting window is employed to design the light shape that meets the regulatory requirements. The LEDs are adopted as light sources. The light emitted by the LEDs forms parallel light through the collimator, and is then scattered and deflected via the free-form surface outer lens so as to meet the relevant regulatory requirements and regulations, thus achieving the effects of illuminating the road surface and preventing glare at the same time.

    摘要： An automotive lamp includes a first lamp unit, a second lamp unit, and a third lamp unit. The first lamp unit illuminates a first region PA1 having its longitudinal direction in the horizontal direction and having its upper edge defining a horizontal cutoff line CL1 in the low-beam mode and the high-beam mode. The second lamp unit illuminates a second region PB1 having its longitudinal direction in an oblique direction inclined with respect to the horizontal direction and having its upper edge defining an oblique cutoff line CL2 in the low-beam mode and the high-beam mode. The third lamp unit illuminates a third region PC1 having its longitudinal direction in an oblique direction inclined with respect to the horizontal direction and having its lower edge parallel to the oblique cutoff line CL2.
