In the present invention, in forming the paraboloid, a rotation paraboloid obtained by rotating the axis passing through the focal point and orthogonal to the central axis, that is, the long axis X of the first reflecting surface 3 is adopted. Therefore, the light that is reflected by the first reflecting surface 3 and converges on the second focal point f2, after being reflected by the second reflecting surface 4,
The light is emitted as a disc shape that is orthogonal to the irradiation direction of the vehicle lamp 1.

で開く角度として設定されている。The reflected light from the second reflecting surface 4 radiated in the form of a disk has a thickness corresponding to the thickness of the second reflecting surface 4 in the irradiation direction. It is the third reflecting surface 5 that reflects the light emitted in the disk shape again toward the irradiation direction of the vehicular lamp 1. Therefore, the third reflecting surface 5 is basically in the irradiation direction. The angle is set to open at 45 °.

面側には光は到達しないものとなる。The arrangement of the second reflecting surface 4 and the third reflecting surface 5 on the substrate portion 6 will be described with reference to FIG. 1. The reflected light from the second reflecting surface 4 is a thin plate. In addition, since the light is generated radially, when the third reflecting surface 5 is provided in the reflected light, the light does not reach the back side of the third reflecting surface 5.

Therefore, when integrally forming the substrate portion 6 with the second reflecting surface 4 and the third reflecting surface 5, the entire body is formed of a transparent member, and aluminum is vacuum-deposited selectively on a portion where a reflecting function is required. The reflective film 6b may be formed by performing the above.

Therefore, a novel lighting state can be obtained as compared with the conventional vehicular lamp. In actual implementation, the lens cut 6a,
The fourth reflecting surface 7 may be provided as necessary, and it is also possible to select only one of them when providing it.

ものである。FIG. 3 shows another embodiment of the vehicular lamp 1 according to the present invention as a main part. In the previous embodiment, the second reflecting surface 4 is formed as a mirror surface having a reflecting film 6b. However, in this embodiment, the surface of the substrate 6 on the irradiation side is projected in a shape corresponding to the second reflecting surface 14,
By utilizing the difference between the refractive index of the member on which is formed and the refractive index of the atmosphere, internal reflection is generated inside the member on the high refraction side, that is, at the second reflection surface 14, thereby eliminating the need for the reflection film 6b.
