By the way, according to the said structure, it is necessary to provide the colored lens which changed the color for every lens with a different purpose of use. In addition, since a light path from each light source to each lens is formed, the inner space of the lens must be partitioned, so that the internal structure becomes complicated, and the partition creates a clear boundary line on the lens surface. .
In addition, all light sources are limited to specific purposes, for example, you may wish to add turn signal emission to tail light emission or vice versa to improve design effectiveness and visibility. There wasn't. Therefore, the present application aims to solve such a conventional problem.

In order to solve the above-mentioned problem, the invention according to claim 1 relating to a vehicle taillight includes a plurality of light sources including a red light source for taillights and a yellow light source for blinkers in a housing, and a ground glass covering these light sources. In a vehicle taillight with a shaped lens,
The lens is composed of an inner inner lens and an outer outer lens, and the ground glass-like lens is an inner lens.
The plurality of light sources are composed of a plurality of LEDs arranged side by side on a substrate provided in the housing, a red LED that is a red light source for taillights is arranged at the center in the left-right direction, and a yellow for blinkers on the left and right A yellow LED as a light source is arranged, and the inside of the lens is a single space without a partition,
When the red light source and the yellow light source are turned on simultaneously, a gradation that forms a gradation-like surface light emitting portion in which red light and yellow light are mixed at the boundary between the central red light emitting portion and the left and right yellow light emitting portions on the lens It is characterized in that a part is formed.

A second aspect of the present invention is characterized in that, in the first aspect, a smoke-like outer lens is overlapped on the outer side of the ground glass-like inner lens with an interval .

According to a third aspect of the present invention, in the second aspect of the present invention, the inner lens and the outer lens are similar to each other having a substantially triangular shape in a side view .

  According to the first aspect of the present invention, when the red light source and the yellow light source are turned on simultaneously, a gradation-shaped surface light emitting portion in which red light and yellow light are mixed is formed on the lens. Since the boundary of the yellow light emitting part can be eliminated, the entire taillight can be made a novel design light emitting surface, and at the same time, the visibility can be improved. In addition, it can emit light using the light for the turn signal lights and the light for the tail lights at the same time.

In addition, a red light source for taillights is arranged in the center, a yellow light source for blinkers is arranged on the left and right, and the inside of the lens is made into a single space without compartments, so a red light source for taillights and a blinker for blinkers are used. If the yellow light source is selected and turned on, the functions of the taillight and the blinker can be realized, and if they are turned on at the same time, the gradation part is formed by actively mixing light of different colors. Can do. In addition, since a single lens is sufficient and it is not necessary to divide the interior into a plurality of parts, the lens can be of a simple structure.

According to the invention of claim 2 , since the ground glass-like inner lens and the smoke-like outer lens overlapped on the outside thereof are provided, the light is dispersed by the inner lens and the outer lens when the light source is turned on. When the light source is not turned on, the outer lens is smoked so that it is difficult to see the inside and the outer lens becomes the outer appearance portion, so that the outer lens can increase the design effect. . In particular, when used as a rear cowl, the vehicle configuration can be simplified.

The main frame portion 16 protrudes in the left-right direction from the sub-frame portion 17 and the connecting portion 30.

  Hereinafter, the taillight 15 will be described in detail. FIG. 3 is an enlarged side view of the taillight 15 portion. The taillight 15 has a substantially triangular shape in a side view in which the rear end vertex 40 protrudes long backward at an acute angle, and the upper surface 41 and the lower surface 42 are the rear end vertex 40. It is inclined obliquely so as to converge backward.

  As shown in FIG. 2, the tail light 15 also has a triangular shape in which the rear end vertex 40 protrudes rearward, and the left side surface 43 and the right side surface 44 also form slopes that converge toward the rear end vertex 40.

FIG. 4 is a view showing the tail light 15 in the lit state from the rear of the vehicle body, and the light emitting portion is displayed in a lattice hatching or a dotted pattern for convenience. The taillight 15 has a shape with a wide width when viewed from the rear, and has a red light emitting portion 45 at the center, a yellow light emitting portion 46 at both left and right ends, and a gradation portion 47 as a boundary portion thereof as light emitting portions. .
However, this state is a state in which a plurality of light sources are all turned on, and various light emission patterns are formed when a plurality of light sources are selectively turned on. The light emission pattern will be described later. The gradation portion 47 is an intermediate portion in which the color gradually changes from yellow to red toward the red light emitting portion 45 from the yellow light emitting portion 46, and is a color portion in which yellow and red are mixed.

  5 is a cross-sectional view taken along line 5-5 of FIG. 4, and the taillight 15 has a lens structure in which an outer lens 50 and an inner lens 51 are stacked on the inside and the outside. The outer lens 50 and the inner lens 51 have a similar triangular shape when viewed from the side, and overlap each other with a slight gap.

The outer lens 50 is a translucent lens made of glass, resin, or the like, for example, colored in a smoke color. The outer lens 50 is a portion that does not make the internal structure visible when not lit and also serves as a rear cowl.
The inner lens 51 is made of glass, resin, or the like, for example, a milky white and textured lens, and diffuses light. Oite herein, it means a state of processing the surface is roughened and with grain, and includes those such as ground glass.

  A front end portion of the taillight 15 is provided with a housing 52 made of a non-translucent material having a substantially triangular shape convex forward in a side view, and an upper inclined surface 52a overlaps a bottom plate 12a in the rear portion 14 of the seat 12. Yes. Therefore, the housing 52 can be supported on the seat 12 and the taillight 15 can function as a rear cowl. A flange portion 52b formed in the peripheral portion of the housing 52 enters between the front end portions of the outer lens 50 and the inner lens 51 and serves as a spacer for these.

  A substrate 53 is provided inside the housing 52, and a plurality of LEDs are attached as a plurality of light sources 54 here, so that they are turned on when the taillight is turned on, when the stop lamp is turned on, and when the blinker is turned on. The position of the central portion of the substrate 53 in the vertical direction coincides with the height of the rear end vertex 40, and the amount of light is maximized at the farthest position.

  Further, by forming a minute gap between the inner lens 51 and the outer lens 50 and bringing the inner lens 51 closer to the outer lens 50 from the light source 54, the light from the light source 54 is blurred to cover the entire surface of the outer lens 50. It is designed to emit light. In this embodiment, the minute gap between the inner lens 51 and the outer lens 50 is about the length of the light source 54 or less.

  Further, by making the inner lens 51 milky white and textured, for example, the light of the light source can be diffused relatively uniformly throughout the taillight 15, so that when the light source 54 is turned on, the surface of the outer portion of the outer lens 50 is visible. The entire surface emits light so that it can be seen from the rear and the side.

  FIG. 6 is a view showing the light source 54 and the substrate 53 from the rear. The light source 54 is composed of two kinds of small light bulbs, a red light source 54a composed of red LEDs and a yellow light source 54b composed of yellow LEDs. The red light source 54a is arranged at the center of the substrate 53, and the yellow light source 54b is red. The light source 54a is disposed on the left and right sides.

  The number and distribution of the red light sources 54a are set so that the red light source 54 emits red light with the amount of light required as a stop lamp or tail light when viewed from the rear of the tail light 15 when turned on. During braking, the voltage is increased to emit light with high brightness. Similarly, the number and distribution of the yellow light source 54b are set so that either the left or right of the yellow light source 54b blinks and the yellow light is emitted in the amount of light required as a blinker lamp in the rear view of the taillight 15.

  In the figure, for convenience, the red light source 54a is painted black and the yellow light source 54b is displayed white. In addition, reference lines for reference numerals are also attached to only a part. The arrangement, distribution density, and the like of the red light source 54a and the yellow light source 54b can be arbitrarily set as necessary.

  Next, the operation of this embodiment will be described. FIG. 7 is a diagram schematically showing the light emission state of the taillight 15 from the rear of the vehicle body. In FIG. 7, A is when all the light sources are not lit, and the taillight 15 as a whole appears as a smoked outer lens 50 and is recognized as a rear cowl.

B is during independent lighting flasher, by flashing light the right or left a yellow light source, it performs the normal winker display left or right side of the yellow light emitting portion 46 is illuminated flashing yellow. As shown in FIG. 6, since the yellow light source 54b is arranged to be biased to the left and right, a portion whose light emission state is biased to either the left or right side is strongly yellow and emits surface light.

  In this figure, for the sake of convenience, the left and right sides are simultaneously lit, but either the left or right side is blinked. At this time, since the outer lens 50 and the inner lens 51 transmit light not only to the rear side of the vehicle body but also to the side of the vehicle body, they can be recognized from the side of the vehicle body on the blinking side.

  C is a single lighting state of the taillight or the stop lamp. When the red light source is turned on, the entire taillight 15 is lit in red, and the surface light is emitted as a taillight during night driving or a stop lamp during braking. When braking at night, the light source is made to emit light strongly by increasing the luminance W of the red light source. Since the red light source occupies the center in the left-right direction and the amount of light when turned on is set to be relatively large, the entire taillight emits light in red, not only from the rear of the vehicle body but also from the side. Can also recognize the taillight 15 emitting red light.

D is when the red light source and the yellow light source are turned on at the same time, and occurs when the blinker is turned on while the tail lamp is turned on, such as when driving at night, or when the blinker is turned on simultaneously with the brake. At this time, in the center, the red light emitting unit 45 is surface-lit in red with a red light source, and the left and right yellow light emitting units 46 also emit yellow light with a yellow light source and blink.
At the same time, the boundary between the yellow light emitting portion 46 and the red light emitting portion 45 forms a gradation portion 47, and gradually changes from yellow to red from the side toward the center.

  For this reason, unlike the prior art, the red light emitting portion and the yellow light emitting portion are not clearly partitioned, and instead of the conventional clear boundary, a gradation portion 47 in which yellow and red are mixed is formed. 47 can form a remarkable design light emitting portion which has never been seen so far, and can improve visibility. Moreover, since the gradation portion 47 is actively used, it is not necessary to partition the light emitting portions of the red light source 54a and the yellow light source 54b in the tail light 15, and the internal structure of the tail light 15 can be simplified.

  In addition, it can emit light using yellow light for turn signals of different colors and red light for tail lights at the same time. In addition, since the interior is a single space without a partition, if the red light source 54a for the taillight and the yellow light source 54b for the blinker are selected and turned on, the functions of the taillight and the blinker can be realized. If these are lit at the same time, light of different colors is actively mixed to form the gradation portion 47. Therefore, the design of the light source using light sources of different colors, which has never been considered before, is used. It can be used synergistically to improve the visual effect and visibility.

  In addition, the inner lens 51 and the outer lens 50 are not complicated such as having a plurality of different colored portions, but a single structure is sufficient, and it is not necessary to divide the inside into a plurality of parts, so that the lens can be configured with a simple structure. It can be made relatively inexpensive.

  Further, by using the outer lens 50 also as the rear cowl, it is possible to simplify the configuration of the vehicle body and reduce the number of parts, and to improve the visibility from the rear and side as a lighting device.

Note that the outer lens 50 is not always necessary, and may be omitted as appropriate. Further, the light source 54 is not limited to the LED, and various known bulb types can be used.
