Abstract

PURPOSE:To make a lighting tool clear and easy to discern at the time of mishandling of brake operation by forming a tail lamp into a profile surrounding a stop lamp, and by driving light sources individually for the tail lamp and for the stop lamp. CONSTITUTION:A lighting tool 1 is formed into a stop lamp 3 and a tail lamp 2 formed into a profile surrounding the stop lamp, through a bulkhead 5c, and a tail lamp light source 7a and a stop lamp light source 7b which are individually lighted, are provided for each. Particularly during the night when the tail lamp 2 is lighted, the tail lamp 2 is normally lighted in the profile thus formed, and the stop lamp 3 situated on the inner side of the tail lamp is lighted following the operation of brake, next to the tail lamp. The shape of the lighting surface will be different to a large degree when the lighting tool works as a tail lamp 2 and when it works as a stop lamp 3, besides the difference in brightness.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp in which a tail lamp and a stop lamp are integrated.

[Conventional technology]

FIG. 6 shows an example of a conventional vehicle lamp 91 of this type, in which a tail lamp filament 94a with relatively low power is installed in an integral lamp body formed by a housing 92 and an outer lens 93. A double filament light bulb 94 with a relatively high power stop lamp filament 94b is provided, and each filament 94a
194b, and by forming the integrated lamp body, the entire surface of the outer lens 93 shines brightly when either filament 94a or 194b is lit, so that the tail lamp is not lit at night. In this state, the lighting of the stop lamp filament 94b in addition to the lighting of the stop lamp filament 94b confirms the lighting of the stop lamp as a difference in brightness on the surface of the outer lens 93.

[Problem to be solved by the invention]

However, in the above-mentioned conventional vehicle lamp 91, since the light emitting surface is shared as described above, the discrimination between a tail lamp, a strike lamp, and a planzo lamp depends solely on the difference in lighting brightness. This identification is done by comparing the brightness of the tail lamp according to the viewer's memory with the brightness of the corresponding vehicle lamp 91, thereby determining whether it is currently lit as a tail lamp or a stop lamp. The lack of clear standards for identification can lead to errors in judgment due to lack of attentiveness, for example, which can lead to rear-end collisions and other problems. has become an issue. Furthermore, as the outer lens 93 is shared by the tail lamp and the stop lamp, it is essential to satisfy both functions, which limits the degree of freedom in design, such as changing the lens shape to match the design of the vehicle. It has become a thing.

[! Means for Solving Problem I The present invention provides a vehicle lamp in which a tail lamp and a stop lamp are combined into an integrated lamp, as a specific means for solving the above-mentioned conventional problems. A light source is formed at the periphery of the stop lamp in a contour shape surrounding the stop lamp, and the light sources of the tail lamp and the stop lamp are each driven individually, and one does not serve as the other. The above-mentioned conventional problems are solved by providing a vehicle lamp characterized by:

【Example】

Next, the present invention will be explained in detail based on an embodiment shown in the drawings. What is indicated by the reference numeral 1 in FIG. 1 is a vehicle lamp according to the present invention, which is different from the conventional example in that the vehicle lamp 1 has a tail lamp 2 and a stop lamp 3 combined as one unit. However, according to the present invention, the stop lamp 3 is formed in the center of the vehicle lamp 1, and the tail lamp 2 is formed in a contour shape surrounding the periphery of the stop lamp 3. Incidentally, the stop lamp 3 is provided with a reflex reflector 4 at an appropriate position as required. FIG. 2 shows the structure of the above-mentioned vehicle lamp 1 in more detail, and this vehicle lamp 1 is basically formed of a housing 5, an outer lens 6, and a light source like the conventional example. The housing 5 has a tail lamp chamber 5a corresponding to the tail lamp 2 and a stop lamp chamber 5b corresponding to the stop lamp 3.
The tail lamp chamber 5a and the stop lamp chamber 5b are respectively provided with a tail lamp light source 7a and a stop lamp light source 7b. The stop lamp light source 7b is connected to a tail lamp switch (not shown) of the automobile, and the stop lamp light source 7b is connected to a similar stop lamp switch (not shown), and by turning on the tail lamp switch, the tail lamp light source 7a is turned on. When the stop lamp switch is turned on, only the stop lamp light source 7b is turned on. In this embodiment, both the tail lamp light source 7a and the stop lamp light source 7b are shown as light sources using a plurality of LED light emitting elements 7, but in this case, the tail lamp chamber 5a in particular is the same as described above. Since it is formed into such a contoured shape, it is narrow and irregularly shaped, so it is appropriate to use the LED light emitting element 7, which is small and generates little heat. At the same time, it is preferable to provide a brightness difference between the tail lamp light source 7a and the stop lamp light source 7b, as in the conventional example, in order to comply with related laws and regulations. Further, the outer lens 6 is formed as one surface that covers both the tail lamp chamber 5a and the stop lamp chamber 5b of the housing 5, and has a shape of, for example, a fisheye lens corresponding to each of the plurality of LED light emitting elements 7. A lens cut 6a is applied to the lamp, thereby satisfying the prescribed light distribution characteristics for a tail lamp and a stop lamp. Next, the effects of the vehicle lamp 1 of the present invention having the above-described structure will be explained. According to the present invention, the vehicle lamp 1 is divided into the stop lamp 3 and the contoured tail lamp 2 surrounding it by a partition plate 5c, and the tail lamp light source 7a and the stop lamp light source 7b are individually lit. By arranging the tail lamp 2, especially at night when the tail lamp 2 is turned on, the tail lamp 2 is normally lit in the shape of its contour, and the tail lamp 2 changes according to the brake operation. The stop lamp 3 on the inside lights up in addition to this, so when it is operating as the tail lamp 2 and the stop lamp 3
In addition to the difference in brightness, the shape of the light emitting surface is also significantly different when operating as a light emitting device. What is shown in FIG. 3 is another embodiment of the present invention, in which L is used as the stop lamp light source 7b in the previous embodiment.
A light bulb 8 is used instead of the ED light emitting element 7, and any available light source may be selected except for the tail lamp chamber 5a which is narrow and irregularly shaped. Further, in the previous embodiment, the tail wrap light source 7a was shown as a row of LED light emitting elements 7, but it may also be equipped as shown in the figure, and the point is that it can be optimized by taking into consideration the design aspect or visibility. It's a good thing. What is shown in FIG. 4 is yet another embodiment of the present invention, and in any of the embodiments described above, the outer lens 6 has a portion corresponding to the tail lamp 2 and a portion corresponding to the stop lamp 3 that are distinguished from each other in appearance. Instead, the tail lamp light source 7a and the stop lamp light source 7b were separated by a partition plate 5c provided on the housing 5, so that they were separated by light when turned on. However, in this embodiment, the surface of the outer lens 6 Corresponding to the partition plate 5c, for example, a metal-colored molding 9 is used to visually separate the tail lamps 2 and the stop lamps 3 from each other. To further facilitate confirmation from a viewer. FIG. 5 shows yet another embodiment installed at the rear of a vehicle. Since the tail lamp 2 has a configuration in which the LED light emitting elements 7 are arranged in a line, the tail lamp 2 can be made into any length and shape to match the design of the vehicle. That is, there is an advantage that the degree of freedom in design settings is significantly improved. In addition, what is indicated by the reference numeral 3 in the figure is a stop lamp formed in a portion surrounded by the outline of the tail lamp 2. The entire area of the tail lamp 2 and stop lamp 3 may be lit, or, if required by law, only both sides may be lit. If only both sides are lit, the central part will be a dummy, but the presence of this part will further improve the sense of unity with the vehicle body. Incidentally, since the operation and effect of each of the above-mentioned embodiments is the same as that of the first embodiment, detailed explanation will be omitted here.

【Effect of the invention】

As explained above, according to the present invention, the tail lamp is formed at the periphery of the stop lamp in a contour shape surrounding the stop lamp, and the light sources of the tail lamp and the stop lamp are each driven individually, so that one drives the other one. By using a vehicle light that is not supposed to be used in combination, the tail lamp and stop lamp are lit in different positions, and as a result, when the brakes are operated, there is a difference in brightness as well as area, The difference in shape also serves as a notification of its operation, making it clear and easy to understand, preventing misunderstandings or oversights, and having a positive effect on improving traffic safety by preventing rear-end collisions. be. Further, even for people with color blindness or color blindness, a large change in brightness difference, such as a non-lit part turning on, is easy to judge, and therefore has the effect of improving visibility. Furthermore, the line-shaped contour part that becomes the tail lamp uses an LED light emitting element as a light source, so there is a large degree of freedom in setting the contour shape.
Another benefit is that it is easy to harmonize with the curves and design of the car body.
