Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a novel vehicular lamp. Specifically, it is a composite lamp that is equipped with at least two light-emitting surfaces and two light sources and serves two or more functions, such as a tail-and-stop lamp and a turn signal lamp, and each of these functions is fulfilled. The object of the present invention is to provide a new vehicle lamp that can increase visibility by increasing the light emitting area as much as possible.

BACKGROUND ART AND THEIR PROBLEMS FIG. 1 shows an example of a conventional combination lamp for an automobile, which performs the functions of two lamps: a tail and stop lamp and a turn signal lamp.

A is the lamp body, the lamp chamber C for the tail and stop lamp, and the lamp chamber C for the turn signal lamp.
and are partitioned by partition walls d. Light source bulbs e and f are arranged in each of the lamp chambers s and c, and further,
The front surface of each lamp chamber S, C is covered by a lens g, h.

The surface of the lens g shines due to the light emitted from the light bulb e,
The lens h shines due to the light emitted from the light bulb f, and functions as a tail and stop lamp or a turn signal lamp, respectively. By the way, since the turn signal lamp flashes when the car turns left or right, in other cases there is little need for it to occupy a large light emitting area, so the light emitting area of the tail lamp can be reduced accordingly. It is preferable to make it larger because it improves visibility from following vehicles.

Purpose of the Invention The present invention has been made in view of the above-mentioned conventional problems, and includes at least two light-emitting surfaces and two light sources, such as a tail-and-stop lamp and a turn signal lamp. The object of the present invention is to provide a new vehicle light that is a composite light that performs two or more functions, and that can increase visibility by increasing the light emitting area as much as possible when performing each function. do.

Summary of the Invention In order to achieve the above object, a first vehicular lamp of the present invention includes a first light source and a second light source in a lamp chamber defined by a lens and a lamp body, and the entire area of the lens is The vehicle lamp of the present invention is characterized in that when the first light source is turned on, the lens emits light in the same color, and when the second light source is turned on, a part of the lens emits light in a color different from the emitted light color. The second type includes a first light source and a second light source in a lamp chamber defined by a lens and a lamp body, and the entire lens emits light in the same color when the first light source is lit, and the second light source emits light in the same color. an outer lamp part in which a part of the lens emits light in a color different from the emitted light color when the light source is turned on; It is characterized in that the color of the light emitted when the second light source of the outer lamp part is turned on is the same color as that of the inner lamp part.

EXAMPLES Below, details of the vehicle lamp of the present invention will be explained according to illustrated examples.

1 is a lamp body made of synthetic resin, and two light bulbs 2 and 3 are attached to it.

Reference numeral 4 designates an outer lens that covers the front surface of the lamp body 1, which has a wrap-around portion 5 on the side and a flat portion 6 that are integrally formed, and is colorless and transparent.

Reference numeral 7 designates an inner lens 6 disposed inside the wrap-around portion 5 of the outer lens 4, and is colored amber.

Reference numeral 8 denotes an inner lens disposed inside the flat portion 6 of the outer lens 4, which is colorless and transparent.

Reference numerals 9 and 10 are inclined inner lenses arranged to be interposed between the light bulb 2.3 and the inch lens 8, with one end approaching each other at the rear and the other end facing toward the front, that is, the inner lens 8. They are arranged at an angle so that the closest position is the furthest apart. The inclined inner lens 9 is red in color. Also, the other inclined inner lens l
It is said to be amber.

The inner lenses 8.9 and 1O are provided with lens elements for controlling the light emitted from the light bulbs 2 and 3 so that the light is emitted forward from the flat part 6 of the outer lens 4. is formed.

Therefore, in the vehicle lamp 11 as described above, the light bulb 3
When turned on, a part of the light passes through the inner lens 7, passes through the wraparound 8I;5 of the outer lens 4, and is emitted. Therefore, the wrap-around portion 5 of the outer lens 4 shines in an amber color. The remaining light emitted from the light bulb 3 passes through the inclined inner lens 10 and the inner lens 8, passes through the flat part 6 of the outer lens 4, and is emitted. Thus, ') [When the bulb 3 is turned on while the bulb 2 is not lit, the flat part 6 of the outer lens 4 also shines in an amber color. In this way, when only light bulb 3 is lit,
The entire surface of the outer lens 4 will be covered with amber.

Next, when the electric lamp J', J< 3 is turned off and the light bulb 2 is turned on, the light passes through the inclined inner lens 9 and the inner lens 8, passes through the flat part 6 of the outer lens 4, and is emitted. . And the light emitted from this *EJ<2 is
At least when the light passes through the inclined inner lens 9, it is colored red, so the flat portion 6 of the outer lens 4 shines red.

Since the vehicle lights All mentioned above are as described above, when displaying by illuminating the light emitting surface 5.6 with two different colors, for example, amber and red as shown in the example -F, one of the vehicle lights The light emitting surface 6 can be shared, and the limited light emitting surface can be made to function effectively.

In addition, in the above-mentioned wheel lamp 11, the emitted light color of the light emitting surface is described as amber and red, but the emitted light color should be selected appropriately depending on the purpose of use, and is limited to amber and red. It is not something that will be done.

FIGS. 4 and 5 show an example 7 of the second embodiment of the vehicle lamp of the present invention, which is applied as a rear combination lamp of an automobile.

Reference numeral 12 denotes a lamp body made of synthetic resin, which is divided into an outer lamp part 14 and an inner lamp part 15 by a partition wall 13.

Reference numeral 16 denotes an outer lens, which is arranged to cover the entire front surface of the lamp body 12. This outer lens 16 has an outer wraparound 881-. 7, a common plane part 18 extending inside the wrap-around part 17, and a tail-and-stop part 19 extending further inside the common plane part 18.
and are integrally formed from transparent synthetic resin.

Light bulbs 20, 21 and 22 are arranged in the lamp body 12. Bulbs 20 and 21 are placed in the outer lamp section 14, with bulb 1+20 for the turn signal lamp and bulb 21 for the tail and stop lamp.

Light bulb 22 is a tail ant stop lamp It is arranged in the inner lamp part 15.

Reference numeral 23 designates an inner lens for a turn signal lamp disposed inside the wrap-around portion 17 of the outer lens 16, and is colored amber.

24 is the common part inner lens, outer lens 1
It is arranged inside the common plane part 18 of :I! !
It is considered to be color II.

25 is an inner lens for the tail and stop lamp, and the tail and stop part 1 of the outer lens 16
It is placed inside 9 and is colored red. - 26 and 27 are inclined inner lenses arranged at 6° so as to be interposed between the light bulbs 20, 21 and the common inner lens 24, with one end approaching each other at the rear and the other end at the front. , that is, the common part inner lens 24 has 6
They are arranged at an angle so that the closest position is the furthest apart. One inclined inner lens 26 is red in color. Further, the other inclined inner lens 27 is amber colored.

In addition, each light bulb 2 is attached to the inner lenses 24, 26, and 27.
A lens element is formed to control the light emitted from the lenses 0 and 21 so that the light is emitted forward from the common plane portion J8 of the outer lens 16.

Therefore, in the vehicle lamp 28↓ as described above, when the vehicle is traveling straight at night, the light bulbs 21 and 22 are turned on. Then, since the light emitted from the light bulbs 21 and 22 is colored red by the inner lenses 26 and 25,
The common plane part 18 and the tail antrum part 19 of the outer lens 16 are respectively made to shine in red. Incidentally, when the vehicle stops traveling, the light bulbs 21 and 22 emit brighter light than when they function as tail lamps, and therefore, the common plane portion of the outer lens 16 and the tail and stop portion 19 are made to emit red light more intensely.

In this way, when driving straight or stopping, turn on the lights F721 and 22.
The red light strip (light emitting surface that functions as a tail lamp) is enlarged in six directions over the two areas of 9 and 9, making it possible for following vehicles to clearly see the presence of the vehicle's own weight.

Next, when making a right or left turn, or when changing the direction of the vehicle, the light fixture placed on the turning side (the axle light fixture 28 shown is the one that is used when turning right) .

) Turn off the light bulb 21, and turn off the light bulb 20. Then, the light t of the light bulb 20 passes through the inner lens 23 and the inner lens 27, 24, and the outer lens 1
The light is emitted from the wrap-around SR 17 and the flat portion 18 of 6, and therefore the wrap-around SR 17 and the flat portion 18 are made to blink in one color.

In this way, when you want to notify following vehicles etc. that you are turning right (or left), etc., the clustered portion 1 of the outer lens 16
Since a wide area covering two areas, 7 and the flat part 18, flashes in amber color, it is possible to clearly inform the drivers of the following cars that their own troops are moving in a new direction and in the direction of the new line.

In addition, in the description of the Nikki Ichisuke lamp 28, the coloring of the light emitted from the light bulb is expressed by the inner lens 23, 25, 26.
27, but this is just one example of ways to color the light. For example, it can be colored by various means, such as adding h color to the glass bulb of a light bulb or using an appropriate filter. It is possible. Also,
It is not necessary that the electric current in each category is addressed to one piece, but may be a tally if necessary. That is, it is sufficient to arrange as many bulbs as necessary, such as using two light bulbs 20 in the turn signal lamp section. Further, the present invention is not limited to a combination of a tail and stop lamp and a turn signal lamp, and can be applied as a composite lamp in various combinations such as a combination of these and a back lamp.

Effects of the Invention As is clear from the above explanation, the vehicular lamp of the present invention includes a first light source' and a second light source in a lamp chamber defined by a lens and a lamp body, and the entire lens area is The main characteristic of this lens is that when the first light source is turned on, it emits light in the same color, and when the second light source is turned on, a part of the lens emits light in a color that is different from the emitted light color. It is possible to greatly improve visibility by increasing the area of the light emitting surface for each purpose as much as possible.
