Description

  The present invention relates to a vehicular lamp that widens the radiation angle of light from a light source by a plurality of reflecting surfaces.

  Vehicle lamps such as tail lamps and stop lamps are required to emit light over a relatively large area. Conventionally, as a method corresponding to such a requirement, a method of arranging a large number of light sources so as to obtain a desired light distribution characteristic or a method of increasing the distance between the light sources and the light emitting surface has been adopted. However, in these methods, increasing the number of light sources consumes a lot of power, resulting in poor efficiency, increasing the number of parts and increasing the cost, increasing the size of the lamp and requiring a lot of space for installation, etc. There was a problem.

  In order to deal with such problems, for example, a vehicular lamp that converts light from a light source having a relatively narrow radiation angle into a wide radiation angle by combining a hyperboloidal reflection surface and a parabolic reflection surface has been proposed. (For example, refer to Patent Document 1).

  As shown in FIG. 13, the vehicle tool described in Patent Document 1 includes a light source 2, a first reflecting surface 3, and a second reflecting surface 4. The first reflecting surface 3 is a rotating hyperboloid having a horizontal axis X as a rotation axis in a hyperbola, and the second reflecting surface 4 is a rotating paraboloid having the same horizontal axis X as a rotation axis. The optical axis is also a horizontal axis X.

  The light source 2 is installed at the first focal point f1, which is one of the two focal points of the first reflecting surface 3. At this time, the optical axis of the light source 2 coincides with the horizontal axis of the hyperbola, and the light emission direction is directed to the hyperbola side. Since the hyperboloid of the first reflecting surface 3 is a convex surface facing the light source 2, the light emitted from the light source 2 has the same directionality as that when the light source exists at the second focal point f2, so that the radiation angle is expanded. Reflected.

  The second reflecting surface 4 is formed as a rotating paraboloid having the second focal point f2 as the focal point f3, and faces the first reflecting surface 3. In the second reflecting surface 4 formed as a paraboloid of revolution, the light from the first reflecting surface 3 is parallel to the front of the lamp as light having the same characteristics as that emitted from the second focal point f2. reflect.
