DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail based on embodiments shown in the drawings.
[0007]
FIG. 1 is a cross-sectional view showing a first embodiment of an automotive signal lamp 1 according to the present invention. The automotive signal lamp 1 has a parabolic reflecting surface 2a such as a rotating parabolic surface formed on the inner surface. A reflecting mirror 2 having an opening on the front surface, a light source 3 having a filament (emission center) 3a disposed at a substantially focal position F1 of the reflecting surface 2a of the reflecting mirror 2, and the light source 3 in the reflecting mirror 2 The holding socket 4 and a clear outer lens 5 covering the front opening of the reflecting mirror 2 are configured to reflect the light from the light source 3 as a substantially parallel light beam in the irradiation direction. At this time, the outer lens 5 is provided with a lens cut 5a in the shape of, for example, a fish-eye lens, and the parallel light beam reflected by the reflecting surface 2a is appropriately diffused to obtain a light distribution characteristic as an automobile signal lamp. The points up to this point are the same as those of the conventional example.
[0008]
Here, in the present invention, the reflecting surface of the reflecting mirror 2 includes a first reflecting surface 2a having the light source 3 as a substantially focal position, and a second reflecting surface 2b having a portion of the socket 4 as a substantially focal position. In addition, the socket 4 is colored in a color other than the functional color of the automobile signal lamp 1.
[0009]
The functional color as the signal lamp 1 for an automobile is, for example, red for a tail lamp or a stop lamp, and amber for a turn signal lamp. The bulb is covered with a functional color coloring cap so that the functional color is emitted when the light source 3 is turned on. Note that the light source 3 may be an LED (light emitting diode), a neon tube, or the like, in addition to a light bulb having a filament at the illustrated light emission center 3a.
[0010]
Further, the socket 4 is formed of a color other than the functional color, for example, a resin colored blue if the functional color is red, or is formed by coating the surface of the socket 4 with a color other than the functional color. The second reflecting surface 2b having a part of which is substantially the focal position F2 is combined with the first reflecting surface 2a, for example, and arranged in the reflecting mirror 2 alternately as shown in the figure. It is.
[0011]
As an example of the combination of the first reflecting surface 2a and the second reflecting surface 2b of the reflecting mirror 2, as shown in FIG. 2, for example, they are alternately arranged in the vertical stripe shape of (a), or the checkered pattern of (b) There are examples such as alternately arranged in a pattern, alternately arranged in concentric circles in (c), and alternately arranged in horizontal stripes in (d). These are merely examples of the combination of the first reflection surface 2a and the second reflection surface 2b, and may be a random combination that is appropriately distributed and arranged instead of such a regular arrangement.
[0012]
Further, since the socket 4 is a member for holding the light source 3, if the focal position F2 of the second reflecting surface 2b is set to a position very close to the light source 3 above the socket 4, the reflecting surface in the reflecting mirror 2 is All may be only the second reflecting surface 2b.
[0013]
In addition, the second reflecting surface 2b of the reflecting mirror 2 has been described as having a part of the socket 4 colored in a color other than the functional color as an automotive signal lamp as a substantially focal position. The reflective surface may be directly colored to a color other than the functional color by coating or the like. In this case, a plurality of locations on the first reflective surface 2a may be colored to form the second reflective surface 2b.
[0014]
By configuring as described above, when the automotive signal lamp 1 is turned on, the light from the light source 3 is irradiated forward as a substantially parallel light beam by the first reflecting surface 2a, and functions as the original automotive signal lamp 1. When the light is emitted in a non-lighting state, the second reflective surface 2b having a part of the socket 4 colored other than the functional color as a focal position causes the second reflective surface 2b to color the socket 4 other than the functional color. It is displayed on the screen to make pedestrians and drivers ahead recognize it. As a result, responsiveness and recognizability to drivers and pedestrians of other vehicles due to the color change (contrast) between the original functional color when the automotive signal lamp is lit and the color other than the functional color projected on the reflective surface when not illuminated. Can be enhanced.
[0015]
【The invention's effect】
