However, in such vehicle lighting equipment, if each light emitting diode unit is made to emit light at the same time,
There was an inconvenience that the colors were mixed together and the clarity of the displayed colors was reduced. Therefore, the back cover is usually provided with a partition wall either integrally or separately.
The light chamber is divided into sections for each light emitting diode unit, but in this case, if the partition wall is integrated with the back cover, manufacturing the mold for the back cover will be troublesome and increase the cost, and if it is formed separately from the back cover, the assembly will be difficult. Another problem arises in that the attachment work is troublesome.

It is securely fixed to the front surface of the back cover 2 via adhesive or the like. A bent portion 3A that is bent along the side of the vehicle body, similar to the bent portion 2A of the back cover 2, is integrally provided at the side end of the front lens 3 on the side of the vehicle body, thereby forming a wraparound lens. ing. The front lens 3 has a large number of light transmitting parts 10 provided at predetermined intervals in the vertical and horizontal directions by masking its surface with a light shielding film 9 of the same color as the vehicle body color. The remaining portion constitutes a light-impermeable portion by the light-shielding film 9, and a group of small lenses consisting of a large number of convex lenses 11 are densely formed on the inner surface.

It is formed of a transparent resin material into a substantially L-shape, and its end is attached to the inner surface of the end of the front lens 3 with a set screw 1.
It is fixed by 2.

スタンプ法等によつて形成されている。 Here, the light emitting diode 6 is divided into two light emitting diode units by using light emitting diodes of different colors, for example, red and yellow. By illuminating the region on the side of the vehicle body including 3A in red, this region constitutes a taillight, and by illuminating the region on the center side of the vehicle body of the front lens 3 in yellow with the other unit, this region serves as a direction indicator. It makes up the light. The light transmitting portion 10 is formed with a predetermined pitch P 1 , P 2 for each region, but the boundary A between the regions is set slightly larger than the pitch P 1 , P 2 of the light transmitting portion 10 .

a and 16b are respectively inserted into the lead wire insertion holes of the circuit board 7 interposed between the diode holding member 5 and the back cover 2, and are soldered by the immersion soldering method. connected to the electrical circuit. In this case, the circuit is configured such that the red light emitting diode unit corresponding to the area emits brighter light than normal by switching the resistance during braking, and the yellow light emitting diode unit corresponding to the area does not normally light up. First, the circuit is configured to blink during the direction change operation.

薄型化できる。 Although it is possible to use a printed circuit board made of general glass epoxy resin or Bakelite as the circuit board 7, it is preferable to use a so-called flexible printed circuit board made of a flexible sheet-like synthetic resin. By doing so, it is desirable to use the flexible substrate itself to absorb manufacturing errors of the light emitting diode 6, assembly errors, manufacturing errors of the small hole 13, etc., and make it easier to insert the light emitting diode into the small hole 13. At the same time, each light emitting diode 6 is
Since the diode is pressed against the peripheral surface of the small hole 13, it is possible to prevent the diode from wobbling, and since it is thinner than a general substrate, the thickness of the lamp can be made even thinner.

す。 In the combination lamp 1 having such a configuration, when the light emitting diodes 6 corresponding to the regions are made to emit light all at once, red light is emitted, and the light transmitting portions 10 of the regions exhibit a red color. On the other hand, when the light emitting diode unit corresponding to the area is blinked by a direction change operation, it emits yellow light when turned on, so that the light transmitting portion 10 of the area appears yellow.

がつて、発光ダイオード６A1，６A2の光は有効
に利用されて損失が少なく、各光透過部１０ａ，
１０ｂを明るく照明する。 Here, if we focus on a certain light emitting diode, for example, the light emitting diode 6A 2 in the second row on the area side counting from the border A, part of the light a 1 passes through the front lens 3 as shown in FIG. The other part of the light a2 is guided into the diode holding member 5, reflected at its critical surface, and then emitted directly to the outside from the light transmitting portion 10b corresponding to the diode.
The light is emitted from the light transmitting section 10a corresponding to the adjacent light emitting diode 6A1 . Similarly, a part of the light b 1 emitted from the light emitting diode 6A 1 is guided into the diode holding member 5 and reflected at its critical surface, and then exits from the holding member 5 and passes through the light emitting diode 6.
The light is transmitted through the light transmitting portion 10b corresponding to A2 . Therefore, the light from the light emitting diodes 6A 1 and 6A 2 is effectively used with little loss, and the light from the light transmitting parts 10a,
10b is brightly illuminated.

ることはない。 Furthermore, a part of the light from the light emitting diode 6A1 guided into the diode holding member 5 also travels to the area side.
A portion of this light hits the light absorption layer 15 and is absorbed, so that the area is not illuminated in red. Similarly, a part of the light emitted from the light emitting diode 6B1 on the side of the area adjacent to the light absorption layer 15 also passes through the inside of the diode holding member 5 toward the area side, but it hits the light absorption layer 15 and is absorbed. Therefore, it does not illuminate the area.

め、領域と領域を明確に仕切る。 Therefore, even if the light emitting diode units on the area side and the light emitting diode units on the area side emit light at the same time, the emitted light colors do not mix with each other near the boundary A, and clear illumination can be achieved. Further, since the boundary part A becomes a band-shaped dark part, it clearly separates one area from another.

In this embodiment, a reflecting part 20 made of a spherical surface whose focal point is the light emitting source of the light emitting diode 6, for example, is provided at the opening on the front lens 3 side of the small hole 13 formed in the diode holding member 5.
0, the light emitted from the light emitting diode 6 is reflected in the direction of the front lens 3 to effectively illuminate the light transmitting section 10, and a light absorbing layer is provided on the front and back surfaces of the diode holding member 5 corresponding to the boundary A between the regions. 1
5A and 15B are formed to further enhance the light absorption effect.

Each area can be illuminated even brighter, and the lighting effect can be improved.

By doing so, it is possible to prevent light leaking from the reflection section 20 to the surface side of the diode holding member 5 from being absorbed by the light absorption layer 15.

As explained above, in the vehicle lamp according to the present invention, a diode holding member that commonly holds at least two light emitting diode units of different luminescent colors is formed of a light guide, and the surface of the holding member holds adjacent diode units. Since the light absorbing layer is formed in the portion corresponding to the boundary, different emitted light colors do not interfere with each other at the boundary, and a clear multicolor display can be performed. Further, since there is no need to provide a partition wall as in the conventional case, it is possible to provide a light fixture with a simple structure, easy manufacturing and assembly work, and low cost.
