Claims

[Claims for Utility Model Registration] Parabolic reflecting surfaces with different focal lengths are combined in multiple stages via stepped portions to form a reflecting mirror, the front is covered with a lens, and the reflecting mirror reflects the light from the bulb. In a vehicle lamp that reflects parallel to the axis, the rear end of the next parabolic reflective surface is located on an extension line connecting the bulb and the front end of the parabolic reflective surface, and The step part is located behind the extension line, and an additional reflective surface is formed on the step part to emit light parallel to the optical axis from the outside in parallel to the optical axis. Vehicle lighting.
