It is composed of

The housing 91 is provided with a direction indicator 90
a, is divided by a partition so as to include three lamp chambers of a tail light / brake light part 90b and a backward light part 90c, and is formed in a substantially box shape with an open front surface, and is integrally formed of, for example, ABS resin. I have. The lens cover 92 and / or the inner lens 95 are provided with a lens cut for diffusing light from the light source 93 and the reflecting mirror 94 so as to satisfy predetermined orientation characteristics. Lens cover 92
Is bonded to the open front surface of the housing 91 to hermetically fix the lamp chamber. The inner lens 95 is provided on the back of the lens cover 92, and separates the light rooms 90a, 90 from each other.
0b and 90c are made of materials of different colors of amber, red and white, and are formed by means of multicolor molding using acrylic resin, for example. An incandescent light bulb is used as the light source 93. The light source 93 is inserted into an opening (not shown) provided in the center of the reflecting mirror 94 from the rear side of the reflecting mirror 94 and fixed. The reflecting mirror 94 has, for example, a paraboloid of revolution having a focus on the light source 93, reflects light emitted from the light source 93 as parallel light, and illuminates the rear of the vehicle body through the lens cover 92.

As shown in FIG. 10, the inner lens 95 is provided with transparent portions 96 and non-transparent portions 97 provided in a stripe shape in the horizontal direction on the irradiation direction side, that is, on the lens cover 92 side. The transmitting portion 97 is coated with a coating film 97a having, for example, a vehicle color. A lens cut 98 is formed coaxially with the transmission part 96 at a position corresponding to the transmission part 96 on the light source side of the inner lens 95. In the lens cut, a so-called flute cut, which is a semi-cylindrical convex cut having a vertical cross section formed at a position corresponding to the transmitting portion 96 and formed in a convex shape, is formed in a stripe shape, and the light source light L incident on the inner lens 95 is formed. Is the transmission part 9

However, in the lamp using the inner lens provided with the coating film described above, the color of the coating film is not viewed unless external light such as daytime enters. When there is little external light incident on the inner lens at night or the like, a uniform impression is lacking. Further, for the above-described reasons, the light emitting surfaces of all the lamps give a similar impression, and there is a demand for a signal lamp for vehicles having a light emitting surface that gives a new impression.

[0008] In view of the above, it is an object of the present invention to provide a vehicular lamp that gives a new impression of having an inner lens provided with a light emitting portion.

[0009]

According to an aspect of the present invention, there is provided a housing, a main light source disposed in the housing, and a lens covering the light source and mounted on an open side of the housing. In a vehicle lamp including a cover and an inner lens disposed on the rear side of the lens cover, the inner lens includes a light transmitting unit and a light emitting unit that uses a light source different from the main light source as a light source. The invention is achieved by a vehicle lamp.

According to this aspect, it is possible to provide a vehicular lamp that emits light also from the inner lens, and can give a novel impression.

The above object is also achieved by another embodiment of the present invention. That is, (2) the vehicular lamp according to (1), wherein the light emitting section is a planar light emitting element light source.

According to this aspect, the inner lens light-emitting portion can be further turned on using the power supply of the vehicle, and at that time, control can be performed with much lower noise than when an inverter or the like for AC driving is used.

The above object is also achieved by the following mode. (4) The composite lighting device for a vehicle according to (1), wherein the light emitting portion is a light emission surface that reflects and / or refracts and emits light from an auxiliary light source provided on a side of the inner lens. According to this aspect, since the light emitting portion can be obtained without providing the self-light emitting element light source on the inner lens surface, an unexpected portion shines when the vehicle lamp is viewed, giving a novel impression. I can do it.

(5) On the main light source side surface of the inner lens, a plurality of light transmitting portions and light emitting portions are alternately arranged in a stripe shape, and on the lens cover side surface, the light emitting portion passes through the inner lens. The object described above is also achieved by the vehicle lamp according to any one of (1) to (4), wherein a lens element for reducing the amount of external light reaching the lens is provided. According to this aspect, when observing the vehicle lamp from the outside, the lens element makes it difficult to directly visually recognize the light emitting section, so that the presence of the light emitting section is weakened, and a portion that does not feel much presence emits light. A vehicular lamp that gives an impression can be provided.

[0014] Further, the above objects are (6) a housing having a plurality of lamp chambers, a main light source disposed in the lamp chamber, a lens cover covering the light sources and mounted on an open side of the housing, and a lens cover. And an inner lens disposed on the back side of the vehicle, wherein the housing has two light rooms arranged side by side, each of which has a main light source, and an inner light source emitted from the main light source.

And an inner lens 5 disposed between the light source and the light source. The light source corresponding to the direction indicator lamp unit 10a is an amber light source 3A covered with an amber color filter.
The light source corresponding to the tail light / brake light unit 10b is a red light source 3R coated with a red filter.
The light source corresponding to 0c is a white light source 3W that emits white light.

The housing 1 is made of ABS resin or the like, and is provided with three lamp chambers separated by partition walls. In each lamp room, for example, a reflecting mirror 4 composed of a paraboloid of revolution or a composite reflecting surface composed of a plurality of reflecting areas and a light source 3 (3A, 3R,
3W) are provided, and the light emitted from the light source 3 is radiated forward as substantially parallel light. The reflecting mirror 4 and the housing 1 may be integrated with each other by forming a reflecting surface on the inner surface of the housing 1. A mounting groove 1a for fixing the inner lens 5 and the lens cover 2 is formed around the open front surface of the housing 1, and the inner lens 5 and the lens cover 2 are fixed in the groove by means such as welding or bonding. I do. In the embodiment of the present invention, the lens cover 2 is made of a transparent acrylic resin,
A lens cut (not shown) is formed on the inner surface of the inner lens 5 side so as to satisfy desired alignment characteristics.

The above configuration is substantially the same as that of the conventional rear combination lamp, but the configuration of the rear combination lamp 10 according to the embodiment of the present invention is different in the following points.

That is, a light emitting section 6 is provided on the surface of the inner lens 5 on the light source 3 side as shown in FIG. FIG.
, The inner lens 5 includes a base 7 made of a transparent material.
And a plurality of light emitting portions 6 arranged in a stripe shape on the surface of the base 7 on the light source 3 side, and a light transmitting portion 8 is formed between the plurality of light emitting portions 6. The base 7 can be made of a light-transmitting material, for example, a resin material such as acrylic or polycarbonate, or a glass base, but it is preferable to use a lightweight resin material having high earthquake resistance. The light emitting section 6 is provided with a self-luminous element light source having a light emitting section for irradiating light while diffusing in a planar shape on the base 7 such that the light emitting surface is on the base 7 side.
When arranging, for example, a plurality of self-luminous element light sources are arranged in a stripe shape such that the light emitting surface of the light emitting element light source is substantially parallel to the road surface.
As the light emitting element light source, for example, an EL element light source using an inorganic compound light emitting layer or an organic compound light emitting layer can be used.

FIG. 3 shows an example of an organic EL element (organic electroluminescent element) light source using a light emitting material made of an organic compound as the EL element light source. The organic EL element light source 20 is, for example, provided with an organic EL element 21 on the surface of the above-described base 7, covers the same with a sealing substrate 22, and adhesively fixes the periphery with a sealant 27 to isolate it from the external atmosphere. . Further, it is preferable that a desiccant 28 is provided between the organic EL element 21 and the sealing substrate 22, for example, on the inner surface of the sealing substrate 22, to adsorb moisture or the like in the sealing space.

The organic EL element 21 is formed by sequentially laminating an anode layer 23 made of an ITO translucent electrode, an organic EL layer 24, and a cathode layer 25 made of a low work function electrode material, for example, by a vapor deposition method. . Further, a sealing layer 26 covering the organic EL element 21 is formed as necessary by, for example, laminating an inorganic compound film and an organic compound film.
As the anode layer 23, nickel, gold, platinum, palladium, alloys thereof, metals having a large work function such as tin oxide and copper iodide, alloys and compounds thereof, and conductive polymers such as polypyrrole are also used. However, a transparent ITO electrode having a large work function is preferably used. As the cathode layer 25, it is preferable to use a metal material having a small work function (low work function metal material) capable of improving electron injection efficiency in order to make the material excellent in electron injection. Aluminum, magnesium, magnesium indium alloy, magnesium Aluminum alloy, magnesium silver alloy, aluminum lithium alloy and the like are preferably used. An electrode having a laminated structure in which an aluminum layer is provided on a thin layer of Li or LiF or the like can also be used.

The organic EL layer 24 contains an organic material capable of obtaining desired light emission from the organic EL layer 24 by applying a current between the two electrodes. For example, in order from the anode layer 23 side,
A two-layer structure of a hole injection / transport layer and an organic light emitting layer, or a three-layer structure further provided with an electron transport layer having a function of facilitating injection of electrons from the cathode layer 25 on the organic light emitting layer, A multi-layered structure or a single-layered structure including a hole injection layer / a hole transport layer / a light emitting layer / an electron transport layer, a hole injection layer / a hole transport layer / a light emitting layer, and a hole transport layer / a light emitting layer / an electron transport layer. Organic E
PEDOT (Poly (3,4) ethylenedio
(xythiophene) It is also possible to use various structures such as a single-layer organic layer via a buffer layer. As the hole transport layer, for example, an aromatic amine derivative ditolyl-diphenyl-biphenyl-diamine (TPD)
And bis (ditolylaminophenyl) cyclohexane (T
For example, tris (8-quinolinolato) aluminum complex (Alq) or the like can be used for the organic light emitting layer of PAC, and the emission wavelength can be changed by adding a dopant to the light emitting layer.

By appropriately adjusting the combination and film thickness of these layers, the organic EL devices currently in practical use can be used.
The light emitting voltage of about 3V of the element may be changed to the light emitting voltage of the power supply voltage of the vehicle such as 12V. For example, 200
Organic EL layer 2 having a thickness of about 0 Å
4 differs depending on the combination of materials used for the organic EL layer 24, but if it is set to about 6000 to 8000 angstroms, the light emitting voltage of about 3V can be changed to the light emitting voltage of 10V or more. Therefore, the lighting can be easily performed by DC drive or pulse drive without generating electromagnetic noise unlike an inverter or the like, and the lighting can be performed at low cost and with minimal adverse effects on other electronic devices mounted on the vehicle. Could be able to.

The vehicular lamp according to the embodiment of the present invention is configured as described above. When the light sources 3A, 3R, and 3W provided in the lamp chambers 10a, 10b, and 10c of the rear combination lamp 10 are turned on, light L emitted from these main light sources emits amber light corresponding to the lamp chambers. Red light and white light that pass through the base 7 and the light transmitting portion 8 of the inner lens 5 and are controlled by the lens cover 2 to have a predetermined light distribution characteristic to illuminate the front of the lamp to perform the function of each lamp chamber. Becomes

When the light source 3 is not illuminated, the light emitting section 6 provided in a stripe shape through the lens cover 2 and the inner lens 5 is viewed. In this state, when the light emitting unit 6 is turned on, light from the light emitting unit 6 is transmitted to the lens cover 2.
And emits light forward of the lamp. When the illuminance of the light emitting unit 6 is made darker than the lighting state of the light source 3, the emission color of the light emitting unit 6 can be visually recognized when viewed from the outside, substantially without substantially illuminating the front of the lamp. Even at night or the like, the appearance of the entire lamp becomes substantially unified by the emission color of the light emitting unit 6 and appeals to a third party. When the light source 3 is turned off, the light emitting unit 6 of the inner lens 5 is turned off.
Also, when the light is not lit, the color of the light emitting portion 6 is visually recognized by the external light, and is appealed to a third party as a substantially uniform appearance color of the entire lamp similarly to the lighting state of the light emitting portion 6. At this time, the color perceived by a third party watching the lamp is the color of the light emitting unit itself that has passed through the lens cover 2 and the inner lens 5 and reflected by the light emitting unit 6.

The light emitting section 6 can be turned on while the light source 3 is turned on, but in this case, the light emission color of the function of each lamp room is not affected. For example, when the light source 3 emits red light by turning on the light source 3, the light-emitting portion 6 emits light of a color that is visually recognized as red, or the light-emitting portion 6 emits light of a different color that is recognized as red as a whole lamp. In addition, although the self-light emitting element light source is directly provided on the base 7 of the inner lens 5 as the light emitting unit 6, the self light emitting element light source manufactured separately may be fixed on the base 7, The light emitting surface may be provided so as to face the side opposite to the base 7. Further, the brightness of the lamp when the light emitting unit 6 is turned on is darker than the brightness (illuminance) of the lamp when the light source 3 which is the main light source is turned on.
It is practically preferable to make only the vicinity of the lamp bright.

FIGS. 4 and 5 show a rear combination lamp 30 and an inner lens 3 of another embodiment.
5 is shown. In the following description, portions having the same functions as those of the above embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The rear combination lamp 30 includes a lens cover 2 having a lens cut so as to satisfy a predetermined standard, and three lamp chambers of a direction indicating light unit 30a, a tail light / brake light unit 30b, and a backward light unit 30c. Substantially box-shaped housing 1 in which the lens cover 2 is attached to an open front surface which is divided by a partition wall.
And a light source 3 disposed in each of the above three lamp rooms;
It comprises a reflecting mirror 4 having a focus on the light source, and an inner lens 35 disposed between the lens cover 2 and the light source 3. A color cap 31A of amber color covers the light source 3 corresponding to the direction indicating lamp unit 30a.
The light source 3 corresponding to the tail light / brake light unit 30b is also provided with a red color cap 31R on the reflector 4.

The inner lens 35 includes a light-transmitting base 37, a plurality of light-emitting portions 36 arranged on the light source 3 side surface of the base 37 in the form of stripes or dots with the light-emitting surface facing the lens cover, and a plurality of light-emitting portions 36. It comprises a light-transmitting portion 38 provided between the light-emitting portions 36, and a lens element 32 is formed on the opposite surface. 5A and 5B show a specific example of the inner lens 35 provided with a lens element. FIG. 5A shows a case in which a convex lens element 32 is formed on the surface of the base 37 on the lens cover 2 side, and FIG. A lens film 33 in which a convex lens element 32 is provided on the surface of the lens cover 2, and a lens film 33 in which a concave lens element 32 and a flat portion 34 are formed on the surface of the substrate 37 on the lens cover 2 side. An example is shown in which a third lens element 39 is attached to the light source 3 side of the base 37 and the convex second lens element 39 is also provided.

In the inner lens 35 shown in FIG. 5A, the lens element 32 is formed in a semi-cylindrical or hemispherical shape, and the light emitting section 36 is disposed at a position corresponding to the space between the plurality of convex lens elements 32. The external light OL that has passed through the lens cover 2 is refracted by the lens element 32 and proceeds toward the light source 3 so that the amount of external light reaching the light emitting unit 36 is reduced.
Thus, when both the light source 3 and the light emitting unit 36 are not turned on, the absolute amount of external light incident and reflected by the light emitting unit 36 can be reduced. Therefore, it is possible to provide a vehicular lamp that makes it difficult to recognize the presence of the light emitting unit 36 when visually recognized from the outside. Also in the inner lens 35 of FIG. 5B, the lens film 33 on which the lens element 32 is formed is adhered to the base 37 so that the relative positional relationship between the lens element 32 and the light emitting section 36 is the same as that of FIG. Has the same effect. In the inner lens 35 shown in FIG. 5C, a lens film 33 having a concave lens element 32 and a flat portion 34 is attached to the surface of the base 37 on the lens cover 2 side, and corresponds to the optical axis of the concave lens element 32. The light emitting section 36 is disposed on the light source side surface of the base 37 at the position where the light emitting section 36 is located.
Accordingly, even when external light OL enters when both the light source 3 and the light emitting unit 36 are not turned on, the light directed toward the light emitting unit 36 is refracted by the concave lens element 32, and the absolute light amount reaching the light emitting unit Is reduced. Therefore, it is possible to reduce the amount of light reflected by the light emitting unit 36 as in (a) and (b). Further, a second lens element 39 is also formed on the light transmitting portion 38 between the light emitting portions 36, and the light L emitted from the light source 3 is mainly emitted through the flat portion 34.

In this embodiment according to the present invention, the inner lens 35 having the light emitting section 36 is provided with a lens element which makes it harder for external light to reach than when no lens cut is provided. When the light emitting unit 36 is not turned on, the light emitting unit 36 is hardly viewed. Further, when the light-emitting unit 36 is lit, the light of the light-emitting unit 36 emitted from a part that is not observed by the viewer gives a novel impression that the light is suddenly viewed, and a substantially uniform impression as a whole of the lamp. To a third party.

FIG. 6 shows an example of another embodiment according to the present invention. In the vehicle lamp 40 of this embodiment,
In the above-described embodiment, the light-emitting portion provided on the inner lens is disposed on the opposite surface on the base 47, and the light-emitting surface is located inside the lamp chamber 40a. That is, in the inner lens 45, the light emitting section 46 is connected to the lens cover 2 of the base 47.
The light emitting surface faces the light source 3 on the side surface. In this embodiment, since the light emitting unit 46 irradiates light to the light source 3 side, when the light emitting unit 46 is turned on, the light room 40a and the reflecting mirror 4 are illuminated, and the light is reflected by the reflecting mirror 4 and the lamp is turned on. The entire interior of the room 40a is illuminated with the color of the light emitted by the light emitting section 46, so that a sense of unity of the entire lamp can be enhanced. Also,
For example, when the lighting color of the light emitting unit 46 is red and the lighting color of the light source 3 is white, when the light source 3 is turned on, the light source 3 emits white light to function as a backward light, and when the light emitting unit 46 is turned on. It is also possible to illuminate the entire lamp in red and to function as a taillight. In this case, the illuminance when the light source 3 is turned on and the illuminance when the light emitting unit 46 is turned on are set to brightness according to the respective functions.

FIG. 7 shows an example of an inner lens portion used in still another embodiment according to the present invention. In the vehicle lamp of the present embodiment, unlike the above-described embodiment, the light emitting portion of the inner lens is different from that of the above embodiment. It does not consist of a self-luminous element light source, but has a light emitting surface for emitting light from a separately provided light source. That is, the auxiliary light source 51 and the auxiliary reflecting mirror 52 are provided below the inner lens 55, and the light emitting unit 56 is provided as a light emitting surface for irradiating the light emitted from the auxiliary light source 51 to the lamp room of the vehicle lamp or to the front of the lamp. I have.

The auxiliary light source 51 is, for example, a cold cathode discharge tube, LE
Light is emitted from the side of the inner lens 55 to the inside of the inner lens 55 using a light source such as a D element or an EL element that can be reduced in size. The auxiliary reflecting mirror 52 has a parabolic cross section having a focus on the auxiliary light source 51, and guides the light emitted from the auxiliary light source 51 into the base 57 with high efficiency. The base 57 is formed of a light-transmitting resin material such as acrylic,
As shown in FIG. 7B, a difference in thickness is provided between the side where the auxiliary light source 51 is provided and a position away from the auxiliary light source, and light from the auxiliary light source 51 emitted into the base 57 guides the inside of the base. To do it. A plurality of light emitting portions 56 are formed on at least one side of the surface to perform light emission processing such as roughening diffusion processing and emit the auxiliary light source light guided inside the inner lens to the outside. I do. The light emitting unit 56 is not limited to the diffusion process, and may be a light emitting surface using refraction / reflection.

In the vehicular lamp using such an inner lens 55, when the auxiliary light source 51 is turned on, the light emitted from the light emitting portion 56 serving as the light emitting surface is observed, and the above embodiment is used. In the same way as above, the lamp as a whole is appealed to a third party with a substantially uniform impression.
Also, the example in which the light from the auxiliary light source 51 is guided into the inner lens 55 has been described. For example, an auxiliary light source is provided at a position P above the base 57 in FIG. Irradiation from the side, the light emitting unit may be a reflecting surface.

Although the above-described embodiment is a preferred specific example of the present invention, various technically preferable limitations are given. However, the scope of the present invention is not limited to these embodiments. Absent. Although the description has been given of the example of the rear combination lamp, various applications such as a vehicle width light, a vehicle lamp provided in a side turn lamp, a rear garnish, and the like are also included in the present invention.
