DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on the embodiments shown in the drawings. The reference numeral 1 in FIG. 1 is a vehicular lamp according to the present invention. As in the conventional example, the light bulb 2 and the LED 3 are provided side by side. It is to be noted that the use of the two kinds of light sources together is for the purpose of improving the reliability, and for example, even when a disconnection occurs on the light bulb 2 side, the LED 3 having a substantially semi-permanent life is turned on. And the vehicle lamp 1 does not completely lose its function.

Here, in the present invention, the LED 3 is also attached to the lens 4. At this time, the lens 4 is made colorless and transparent and the case portion of the LED 3 which is one light source. 3a is also colorless and transparent, and the case portion 3a is attached so as to project to the irradiation direction side, that is, to the outside.

At this time, the lens 4 to which the LED is attached is the outermost one except the one that does not perform an optical action, such as the cover lens 5 provided to match the shape of the vehicle body, and therefore, The case 3a of the LED 3 is in a state in which it can be viewed from the outside of the vehicular lamp 1.

Further, the other light source, which is the light source 2, is provided with a reflecting mirror 6 having a paraboloid of revolution, and the light from the light bulb 2 is made to enter the lens 4 as parallel rays. At this time, the light bulb 2 is provided with a filter 7 having a cap shape and the like, and the light from the light bulb 2 is adjusted to have the same color as the light emitted from the LED 3.

The case 3a of the LED 3 is provided at a position of the lens 4 other than the position where the LED 3 is attached.
Since the dummy portion 4a having the same shape as the above is provided, and the dummy portion 4a is provided so as to project toward the outside of the lens 4, the vehicular lamp 1
The case portion 3 of the LED 3 when viewed from the outside
It is made difficult to distinguish from a. still,
At this time, the case portion 3a and the dummy portion 4 of the LED 3 are
"a" is arranged with an appropriate arrangement so as to match the design of the automobile, for example.

In addition, the dummy portion 4a of the lens 4
An opaque film 4b is formed at a position other than where is provided by either aluminum vapor deposition or coating with an opaque paint from either surface (in this embodiment, the back surface side of the lens 4 is shown as an example. For an example of the case of applying to the front side, refer to FIG. 2), and the opacity processing is performed, so that the light from the light bulb 2 entering the lens 4 is for the vehicle only from the dummy portion 4a. The light is emitted to the outside of the lamp 1.

In the above description, the reflecting mirror 6 is used as means for making the light from the light bulb 2 incident on the lens 4 as parallel rays, and the filter 7 is used as means for coloring the light. However, this is made into parallel rays by using the inner lens 8 having the Fresnel lens cut 8a as shown in FIG. 2, and at the same time, the inner lens 8 is colored in an appropriate color such as red or amber. The light of the light bulb 2 may be colored with.

Next, the operation of the present invention having the above structure,
To explain the effect, in a state where the vehicular lamp 1 is not turned on, the lens 4 surface and the case portion 3a are formed as colorless and transparent, so that they are viewed as the color of the opaque coating 4b. Thus, for example, by setting the opaque coating 4b to the body color or the like, it is possible to improve the compatibility with the automobile design.

When the LED 3 is turned on, the case portion 3a of the LED 3 and the dummy portion 4a emit light of the same color, which functions as a tail light, a direction indicator light, and the like, and the case portion 3a and the dummy portion 4a. Since and have the same shape, it is not recognized that they emit light from different light sources, that is, they all look like a vehicle lamp 1 that is composed of LEDs 3, It will prevent the viewer from feeling uncomfortable.

FIG. 3 shows another embodiment of the present invention. In all the previous embodiments, the light from the light bulb 2 is made to enter the dummy portion 4a of the lens 4 as parallel rays. On the other hand, in this embodiment, the reflecting mirror 5 or the second inner lens 9 in which a light-converging cut 9a is provided in the light flux which is a parallel light beam from the inner lens 8 is provided.

Here, the condensing cuts 9a are formed so as to correspond to the respective dummy parts 4a in a one-to-one correspondence with each other, and further, for example, have a convex lens shape to converge the parallel light rays. It is assumed that the light is incident on the dummy part 4a in the above manner. With this configuration, the brightness of the dummy part 4a when the light bulb 2 is turned on can be freely adjusted by changing the aperture D of the light collecting cut 9a. As a result, the brightness of the LED 3 can be matched.

In implementing the present invention, the light source of the light bulb 2 and the LED 3 are separated, and when the light bulb 2 is turned on, for example, it functions as a taillight with relatively low illuminance.
When the ED3 is turned on, one lens surface may be used so as to function as a braking light with relatively high illuminance,
Alternatively, the light bulb 2 portion and the LED 3 portion may be provided separately in position, the emission colors may be changed, and one may be used as a direction indicator light and the other as a tail light.

[0018]

As described above, according to the present invention, light from a light bulb is incident on the optically outermost one of the lenses from the back side, and the LED has a case portion protruding outward. By providing a dummy part that is mounted so as to have the same shape as the case part of the LED from the lens surface and projects to the outside, and the opaque processing is performed excluding the dummy part, when not lighting, The lens surface has a uniform appearance due to the outer shape formed by the case portion and the dummy portion which are formed to have substantially the same shape on the lens surface, and the opaque processing described above. A sense of alignment can also be obtained.

Further, even when the light is turned on, only the case portion and the dummy portion having substantially the same shape shine due to the shape of the lens surface having the above-described configuration and the opaque treatment, and all the LEDs are LEDs. As a result, the viewer is made to see as if it is configured, and it is possible to prevent the viewer from feeling uncomfortable and to exert an extremely excellent effect in improving the design of this type of vehicular lamp.
