ングである。Next, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and 2 is a composite signal lamp for a vehicle (hereinafter, simply referred to as a lamp).
As shown in the front view in FIG. 2, the first light emitting surface of the first lamp 20
The second light emitting surface 31 of the second lamp 30 is shaped to cut into 21,
As a result, the first light emitting surface 21 is divided into the main light emitting surface 21a and the
1b is the same as that of the conventional example, but according to the present invention, the auxiliary light emitting surface 21b also emits light. In the following, the present invention will be described in more detail.The first lamp 20 includes a first light emitting surface 21, that is, a front lens, an inner lens 22, a first light source 23, and a light guide plate 24. It is supposed to function as a tail light / brake light. At the same time, on the back surface of the second light emitting surface 31 provided in the first light emitting surface 21, a reflecting mirror 32 and a second light source 33 are disposed to constitute a second lamp 30, and the second lamp 30 is formed. The lamp 30 functions as, for example, a direction indicator lamp. Here, the light guide plate 24 is formed using a transparent member such as a resin, and a condensing portion 24a that faces the first light source 23 and introduces the light of the first light source 23 into the light guide plate 24. A light guide 24b for transmitting light to the sub-light emitting surface 21b bypassing the back surface of the reflecting mirror 32, and a reflection cut 24d for emitting light from the light guide 24b toward the sub-light emitting surface 21b are provided. Each of the light emitting portions 24c is formed. The operation and effect of the lamp 1 of the present invention having the above-described configuration will be described below. First, the first lamp 20 and the second lamp 30 are structurally integrated, Are independent of each other, and can be freely turned on and off independently for each purpose. Here, when the first lamp 20 is turned on, the light from the light source 23 guided by the light guide plate 24 is
b also becomes brilliant, and is not recognized as a different shape between day and night. 3 and 4 show a second embodiment of the present invention. The previous embodiment bypasses the back surface of the second lamp 30 and the light source of the light source 23 of the first lamp 20. While the light was transmitted to the auxiliary light emitting surface 21b, in this embodiment, the second lamp was used.
30 is to bypass the upper and lower side surfaces 21c. To explain the operation and effect of such a configuration, if the second lamp 30 is designed in a shape in which the second lamp 30 is embedded in the integrated first lamp 20 as shown in the figure, If the upper and lower side surfaces 21c of the second lamp 30 are not caused to emit light at the same time as the sub-light emitting surface 21b at the time of lighting at night, the sense of unity is lost and a sense of incongruity is caused. Therefore, the light guide plate 24 is provided on the upper and lower side surfaces 21c.
And the reflection cuts 24d are also provided in the upper and lower side surfaces 21c, so that all of the visible light-emitting surfaces of the first lamp 20 can be made to shine. FIG. 5 shows a third embodiment of the present invention. In each of the previous embodiments, the reflecting mirror 32 provided only for the second lamp 30 and the secondary light emission of the first lamp 20 are shown. Focusing on the fact that both the light guide plate 24 provided only for the surface 21b and the light guide plate 24 were provided extremely close in position, the two light guide plates 24 and the light guide plate 24 were integrated into a light guide plate. The reflector 41 is a member such as a transparent resin, the concave surface 41a of which is the second lamp 30.
Along with forming the reflector, the light collector 41b is formed toward the first light source 23 of the first lamp 20, and at the same time, the light emitting part 41c facing the sub light emitting surface 21b is formed. Naturally, the light emitting section 41c is also provided with a reflection cut 41d. The concave surface 41 of the light guide reflecting mirror 41 formed as described above
On the inner surface of a, a reflection film 42 is formed by means of, for example, aluminum vapor deposition, whereby all the light from the second light source 33 is reflected toward the second light emitting surface 31, and the first lamp 20
Thus, interference such as crosstalk does not occur. Here, if the light source 23 of the first lamp 20 is turned on, the light incident from the light condensing portion 41b reaches the light emitting portion 41c via the concave surface 41a and irradiates the sub light emitting surface 21b. Also, the interference with the second lamp 30 does not occur due to the function of the reflection film 42. Note that the parts described above are the same as those of the previous embodiment in this embodiment, and a detailed description thereof will be omitted. In addition, what is indicated by reference numeral 5 in the drawing is a housing of the lamp 1.

提供できる効果も併せてそうするものとなる。As described above, according to the present invention, a configuration in which the light of the light source provided on the main light emitting surface side of the first lamp is transmitted to the sub light emitting surface by the light guide plate bypassing the back surface or the back surface of the second lamp. By doing so, it is possible to turn on the auxiliary light emitting surface, and at night, that is, a place where no light is emitted at the time of lighting, and it is viewed as if the shape is different from that at daytime, that is, at the time of non-lighting, and it is possible to prevent discomfort At the same time, the visibility of the lamp from the side is improved, and the safety is improved. In addition, since the light guide plate also serves as the reflector of the second lamp, there is no need to prepare a separate light guide plate, and the number of parts can be reduced to approximately the same as that of the conventional lamp, and the cost increase is minimal. In addition to this, the effect of being able to provide a lamp with excellent performance at low cost is also achieved.
