[0009] [Figure 1] 1 is a front view of a vehicle equipped with a vehicle lamp according to an embodiment of the present invention, viewed from the rear side; [Figure 2] 2 is a cross-sectional view of the vehicle lamp taken along line AA shown in FIG. 1. [Figure 3] FIG. 10 is a cross-sectional view showing another example of the configuration of a vehicle lamp. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings used in the following description, the dimensions of the components may be shown at different scales to make them easier to see, and the dimensional ratios of the components may not necessarily be the same as in reality.

[0011] In addition, in the drawings shown below, an XYZ Cartesian coordinate system is set up, with the X-axis direction representing the front-to-rear direction (length direction) of the vehicle, the Y-axis direction representing the left-to-right direction (width direction) of the vehicle, and the Z-axis direction representing the up-to-down direction (height direction) of the vehicle.

[0012] As an embodiment of the present invention, a vehicle lamp 1 shown in Figs. 1 and 2 will be described. 1 is a front view seen from the rear side of a vehicle B equipped with the vehicle lamp 1. FIG 2 is a cross-sectional view of the vehicle lamp 1 taken along line AA shown in FIG ...3 is a front view of the vehicle B equipped with the vehicle lamp 1. FIG 4 is a front view of the vehicle B equipped with the vehicle lamp 1.

[0013] 1, the vehicle lamp 1 of this embodiment includes rear combination lamps RCL mounted on both corners on the rear end side of a vehicle B, and lid lamps LID mounted on both the left and right sides of a back gate or trunk lid of the vehicle B. The rear combination lamps RCL and lid lamps LID are arranged side by side in the width direction of the vehicle B (hereinafter referred to as the "vehicle width direction").

[0014] In this embodiment, the configuration of the vehicle lighting fixture 1 will be explained using as an example the lid lamp LID and rear combination lamp RCL located on the right rear side of the lid lamp LID and rear combination lamp RCL that are arranged symmetrically on the left and right sides at the rear of the vehicle B.

[0015] In the following description, unless otherwise specified, the terms "front," "rear," "left," "right," "upper," and "lower" refer to the respective directions when the vehicle lamp 1 is viewed from the front (rear of vehicle B). Therefore, the respective directions when vehicle B is viewed from the front (forward of vehicle B) are reversed from the front, rear, left, and right directions.

[0016] The vehicle lamp 1 of this embodiment includes a first light-emitting area E1 that emits red light in the lid lamp LID, a second light-emitting area E2 that emits red light in the rear combination lamp RCL, and a third light-emitting area E3 that emits red light between the first light-emitting area E1 and the second light-emitting area E2.

[0017] The first light emitting area E1, the second light emitting area E2, and the third light emitting area E3 function as taillights, and form a continuous light emitting surface E in the vehicle width direction when viewed from the front.

[0018] As shown in Figure 2, the lid lamp LID has a first housing 2A with an open front, a first lamp body 4A consisting of a transparent first outer lens 3A covering the opening of the first housing 2A, and a first light-emitting unit 5A arranged inside the first lamp body 4A.

[0019] The first light-emitting unit 5A has a first light source (not shown) and a first inner lens 6A.

[0020] In the first light-emitting unit 5A, the first light L1 emitted from the first light source enters the first inner lens 6A from one end (base end) side thereof, and is guided toward the other end (tip end) of the first inner lens 6A while being repeatedly reflected inside the first inner lens 6A. The first light L1 is also reflected by a plurality of reflection cutouts (not shown) provided on the back side of the first inner lens 6A and is emitted to the outside from the front side of the first inner lens 6A.

[0021] As a result, in the lid lamp LID, the first light emitting area E1 on the front side of the first outer lens 3A (first lamp body 4A) can be made to emit red light by the first light emitting unit 5A.

[0022] As shown in Figure 2, the rear combination lamp RCL has a second housing 2B with an open front, a second lamp body 4B consisting of a transparent second outer lens 3B covering the opening of the second housing 2B, and a second light-emitting unit 5B arranged inside the second lamp body 4B.

[0023] The second light emitting unit 5B has a second light source (not shown) and a second inner lens 6B.

[0024] In the second light-emitting unit 5B, the second light L2 emitted from the second light source enters the second inner lens 6B from one end (base end) side thereof and is repeatedly reflected inside the second inner lens 6B, while being guided toward the other end (tip end) side thereof. The second light L2 is also reflected by a plurality of reflection cutouts (not shown) provided on the back side of the second inner lens 6B and is emitted to the outside from the front side of the second inner lens 6B.

[0025] As a result, in the rear combination lamp RCL, the second light emitting area E2 on the front side of the second outer lens 3B (second lamp body 4B) can be made to emit red light by the second light emitting unit 5B.

[0026] The first light source and the second light source are light emitting elements such as light emitting diodes (LEDs) that emit red light, etc. The number of the first light source and the second light source is not limited to one, but may be multiple.

[0027] The first inner lens 6A and the second inner lens 6B are made of a light-transmitting material such as a transparent resin such as polycarbonate or acrylic, or glass. Of these, the first inner lens 6A is provided so as to extend from the inner side in the vehicle width direction facing the first light source toward the outer side in the vehicle width direction. On the other hand, the second inner lens 6B is provided so as to extend from the outer side in the vehicle width direction facing the second light source toward the inner side in the vehicle width direction.

[0028] In the vehicle lamp 1 of this embodiment, the first housing 2A and the second housing 2B have portions of their opposing sides, separated by a gap G formed between the first lamp body 4A and the second lamp body 4B, that are made of light-transmitting members 20A, 20B.

[0029] The first housing 2A and the second housing 2B are formed by two-color molding of a resin portion having light transparency that becomes the light-transmitting members 20A, 20B and the other resin portion that does not have light transparency.

[0030] The first lamp body 4A has a configuration in which a light-transmitting member (hereinafter referred to as the "first light-transmitting member") 20A on the first housing 2A side and a first outer lens 3A are butted together and integrated.

[0031] The second light body 4B has a configuration in which a light-transmitting member (hereinafter referred to as the "second light-transmitting member") 20B on the second housing 2B side and a second outer lens 3B are butted together and integrated.

[0032] That is, the butt joint between the first housing 2A and the first outer lens 3A and the butt joint between the second housing 2B and the second outer lens 3B are joined together using a welding method such as laser welding or ultrasonic welding.

[0033] In addition, the first light body 4A and the second light body 4B are light-transmitting at the butt joint between the first light-transmitting member 20A and the first outer lens 3A and at the butt joint between the second light-transmitting member 20B and the second outer lens 3B, respectively.

[0034] The first light-transmitting member 20A has a protruding portion 31 protruding from the rear surface side of the first light body 4A, and a light-guiding and emitting portion 32 located on the tip side of the protruding portion 31.

[0035] The second light-transmitting member 20B has an extension portion 33 that extends from the back side of the second light body 4B to a position opposite the protrusion 31, and a light-guiding incident portion 34 that is located at the tip side of the extension portion 33.

[0036] A third light source 35 that emits a third light L3 toward the first light-transmitting member 20A is disposed inside the first light body 4A.

[0037] The third light source 35 is formed of a light-emitting element such as an LED that emits red light. The number of third light sources is not limited to one, but may be multiple. The third light source 35 is disposed on the circuit board 36 and emits third light L3 toward the rear side of the first light body 4A.

[0038] The circuit board 36 is disposed between the first housing 2A and the first inner lens 6A. A light-shielding member 37 is disposed inside the first lamp body 4A to block light between the circuit board 36 and the first inner lens 6A and between the first inner lens 6A and the first light-transmitting member 20A.

[0039] The first light-transmitting member 20A has an incident portion 38 through which the third light L3 emitted from the third light source 35 enters the inside of the first light-transmitting member 20A. The incident portion 38 is provided to protrude from a position facing the third light source 35 of the first light-transmitting member 20A.

[0040] The incident portion 38 allows the third light L3 emitted from the third light source 35 to enter the inside of the first light-transmitting member 20A. A portion of the third light L3 incident from the incident portion 38 is guided toward the tip side of the protrusion 31 while being repeatedly reflected inside the first light-transmitting member 20A.

[0041] Also, part of the third light L3 incident from the incident portion 38 is repeatedly reflected inside the first light-transmitting member 20A and is guided toward the portion where the first outer lens 3A butts against it.

[0042] The light guiding output section 32 and the light guiding input section 34 face each other across a gap G. This allows the third light L3 emitted from the light guiding output section 32 to the tip side of the protrusion 31 to the outside of the first light-transmitting member 20A to enter the extension section 33 (second light-transmitting member 20B) from the light guiding input section 34.

[0043] The third light L3 incident from the light guide incident portion 34 is repeatedly reflected inside the extension portion 33 (second light-transmitting member 20B) and is guided toward the portion where the extension portion 33 butts against the second outer lens 3B.

[0044] The extension 33 has a plurality of reflection cuts 39 on the rear side at a position corresponding to the third light-emitting area E3. The plurality of reflection cuts 39 need only reflect the third light L3 incident on the rear side of the extension 33 at an angle at which the third light L3 is emitted (transmitted) from the front side of the extension 33 to the outside, and there are no particular limitations on the shape, size, number, etc. of the reflection cuts 39.

[0045] In this embodiment, the multiple reflection cuts 39 are, for example, composed of grooves with an approximately triangular cross section that cut out the back side of the extension portion 33 in a direction perpendicular to the direction in which the extension portion 33 extends (in this embodiment, the up and down direction).

[0046] The third light L3 reflected by the plurality of reflection cuts 39 is emitted to the outside of the extension 33 (second light-transmitting member 20B) from an emission surface 40 provided on the front side of the extension 33. The third light L3 emitted from the emission surface 40 is also emitted from the gap G toward the front side between the first outer lens 3A and the second outer lens 3B.

[0047] As a result, in the vehicle lamp 1 of this embodiment, it is possible to make the third light-emitting area E3 located between the first light-emitting area E1 and the second light-emitting area E2 in the vehicle width direction emit red light.

[0048] In addition, in the vehicle lamp 1 of this embodiment, the third light L3 guided through the butt joint between the first housing 2A and the first outer lens 3A and the butt joint between the second housing 2B and the second outer lens 3B is emitted to the outside from the front side of the first inner lens 6A and the front side of the second inner lens 6B.

[0049] That is, in the vehicle lamp 1 of this embodiment, a portion of the third light L3 guided inside the first light-transmitting member 20A is emitted to the outside from the front side of the first outer lens 3A, and a portion of the third light L3 guided inside the second light-transmitting member 20B is emitted to the outside from the front side of the second outer lens 3B.

[0050] As a result, in the vehicle lamp 1 of this embodiment, it is possible to emit red light between the first light-emitting area E1 and the third light-emitting area E3 in the vehicle width direction, and between the second light-emitting area E2 and the third light-emitting area E3 in the vehicle width direction.

[0051] Therefore, in the vehicle lamp 1 of this embodiment, the first light-emitting area E1 on the lid lamp LID side, the second light-emitting area E2 on the rear combination lamp RCL side, and the third light-emitting area E3 located between the first light-emitting area E1 and the second light-emitting area E2 can be made to emit red light as a single connected light-emitting surface E.

[0052] As described above, in the vehicle lamp 1 of this embodiment, it is possible to improve the appearance of the light emitted between the lid lamp LID and the rear combination lamp RCL.

[0053] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0054] For example, in addition to the above-mentioned configuration, the vehicle lamp 1 is provided with a bezel 51 for blocking light from the back side of the second lamp body 4B, as shown in FIG.

[0055] Furthermore, in the vehicle lighting device 1, the inner end of the bezel 51 in the vehicle width direction is pressed against the weatherstrip 52 attached to the body 101 on the rear combination lamp RCL side of the vehicle B, thereby ensuring watertightness between them. The weatherstrip 52 is a packing that elastically deforms by coming into close contact with the body 102 on the lid lamp LID side of the vehicle B, ensuring airtightness and waterproofness between them.

[0056] On the other hand, in the above-mentioned vehicle lighting fixture 1, a rib 42 protruding from the back side of the second housing 2B is pressed against a gasket 53 attached to the body 103 on the lid lamp LID side of vehicle B, thereby ensuring watertightness therebetween.

[0057] Furthermore, although the above-mentioned vehicle lamp 1 is configured to include the third light source 35, it is also possible to omit the third light source 35, for example, as in the vehicle lamp 1A shown in Figure 3.

[0058] Specifically, in the vehicle lamp 1A shown in FIG. 3, the third light source 35 is omitted, and therefore the incident portion 38 is also omitted.

[0059] The first light-transmitting member 20A has a first incident portion 43 through which a part of the first light L1 that causes the first light-emitting area E1 to emit light is incident therein.

[0060] The first incident portion 43 is provided at a position opposite to the tip of the first inner lens 6A, and allows the first light L1 emitted from the tip of the first inner lens 6A to enter the inside of the first light-transmitting member 20A.

[0061] The first light-transmitting member 20A also has a plurality of inclined first reflecting surfaces 44a, 44b, 44c at a position facing the first incident portion 43 and at each bending position of the extension portion 33.

[0062] As a result, the first light L1 incident from the first incident portion 43 is guided toward the tip side of the protrusion 31 while being repeatedly reflected inside the first light-transmitting member 20A.

[0063] The second light-transmitting member 20B has a second incident portion 45 that allows a portion of the second light L2 that causes the second light-emitting area E2 to emit light to enter the second light-transmitting member 20B. The second incident portion 45 is provided at a position opposite to the tip of the second inner lens 6B, and allows the second light L2 emitted from the tip of the second inner lens 6B to enter the second light-transmitting member 20B.

[0064] The second light-transmitting member 20B also has a plurality of second reflecting surfaces 46a, 46b, 46c that are inclined at a position facing the second incident portion 45 and at each bending position.

[0065] As a result, the second light L2 incident from the second incident portion 45 is guided toward the tip side of the extension portion 33 while repeatedly being reflected inside the extension portion 33 (second light-transmitting member 20B).

[0066] In the vehicle lamp 1A of this embodiment, the first light L1 emitted from the light-guiding exit portion 32a located at the tip side of the protrusion 31 to the outside of the first light-transmitting member 20A enters the inside of the extension portion 33 (the second light-transmitting member 20B) from the light-guiding entrance portion 34a located at the tip side of the extension portion 33.

[0067] Furthermore, the first light L1 incident from the light guide incident portion 34a is repeatedly reflected inside the extension portion 33 (second light-transmitting member 20B) and is guided toward the portion where it butts against the second outer lens 3B.

[0068] On the other hand, the second light L2 emitted from the light guiding exit portion 32b located at the tip side of the extension portion 33 to the outside of the extension portion 33 (second light-transmitting member 20B) enters the inside of the protrusion 31 (second light-transmitting member 20B) from the light guiding entrance portion 34b located at the tip side of the protrusion 31.

[0069] The second light L2 incident from the light guide incident portion 34b is repeatedly reflected inside the first light transmitting member 20A and is guided toward the portion where the first outer lens 3A butts against the first outer lens 3A.

[0070] The first light L1 and the second light L2 reflected by the plurality of reflection cuts 39 are emitted to the outside of the extension 33 (second light-transmitting member 20B) from an exit surface 40 provided on the front side of the extension 33. The first light L1 and the second light L2 emitted from the exit surface 40 are also emitted from the gap G toward the front side between the first outer lens 3A and the second outer lens 3B.

[0071] As a result, in the vehicle lamp 1A of this embodiment, it is possible to cause the third light-emitting area E3 located between the first light-emitting area E1 and the second light-emitting area E2 in the vehicle width direction to emit red light by using the first light L1 that enters the inside of the first light-transmitting member 20A from the first incident portion 43 and the second light L2 that enters the inside of the second light-transmitting member 20B from the second incident portion 45.

[0072] In addition, by using the first light L1 and the second light L2, it is possible to emit red light between the first light-emitting area E1 and the third light-emitting area E3 in the vehicle width direction, and between the second light-emitting area E2 and the third light-emitting area E3 in the vehicle width direction.

[0073] Therefore, in the vehicle lamp 1A of this embodiment, the first light-emitting area E1 on the lid lamp LID side, the second light-emitting area E2 on the rear combination lamp RCL side, and the third light-emitting area E3 located between the first light-emitting area E1 and the second light-emitting area E2 can be made to emit red light as a single connected light-emitting surface E, and the appearance of the light emitted between the lid lamp LID and the rear combination lamp RCL can be improved.

[0074] In the above-described vehicle lamp 1, 1A, for example, the second light emitting area E2 can be made to function as both a tail lamp and a brake lamp by emitting strong red light from the second light emitting area E2 during braking. [Explanation of symbols]
