Vehicle light body structure

The invention relates to a lamp body structure of a vehicle, which mainly relates to a lamp body which can have both light-transmitting warning and two levels of light shape.

The lamp body used in the conventional vehicle is mainly provided with a lens in front of the illuminant, and the light can be transmitted through the lens when the illuminant is emitted, and can illuminate the front of the lens to have illuminating and warning effects, but the foregoing structure can generally only output. Corresponding to the light shape generated by the position of the illuminant via the lens, there is no light shape change function.

US Pat. No. 7,248,874 discloses a tunnel light-shaped headlight, and has a two-way mirror with a total reflection surface behind the lampshade, and an annular piece is arranged on the inner edge of the lampshade corresponding to the front side of the two-way mirror, and the number of the annular sheet is distributed. The illuminant further comprises a one-way mirror arranged in parallel with the two-way mirror in front of the corresponding ring of the lamp cover, and the unidirectional mirror partially transparent front surface and partially transparent rear surface, and the illuminant emits light to and from the two-way mirror and the single Reflected between the mirrors and viewed from the outside of the one-way mirror to provide a continuous rearward tunneling pattern.

Although the foregoing structure can generate a hierarchical light shape to have different light shape effects, the light emitted by the illuminant cannot be transmitted by the one-way mirror, and thus the brightness warning effect is poor, and the light shape is matched with the illuminant. The arrangement is arranged in a distinct point-like hierarchy with no obvious missing highlights.

It is an object of the present invention to provide a vehicle light body that can have a light warning and a gradation light shape.
