[0012] An embodiment of a vehicle lamp embodying the present disclosure will be described below with reference to the drawings. In the following description, the outer cover 5 side is the front side (near side) of the lamp, and the housing 6 side is the rear side (rear side) of the lamp. In addition, in the vehicle lamp 1 of the present disclosure and the conventional vehicle lamp 11, the same components are denoted by the same reference numerals and described.

[0013] 1 and 2 is used as a tail lamp 1-1, a stop lamp 1-2, and a turn signal lamp 1-3. In addition, the vehicle lamp 1 of the present disclosure can also be used as a headlamp or the like.

[0014] The vehicle lamp 1 includes a light source 2 such as an LED, a light guide 3 that guides light from the light source 2, an inner lens 4 that adjusts the light L from the light guide 3, an outer cover 5 that transmits the light L from the light source 2 that has passed through the inner lens 4 to the outside of the lamp, and a housing 6. The inner lens 4, the outer cover 5, and the housing 6 can be made of a resin material such as polycarbonate.

[0015] The light guide 3 includes a first light guide 3-1, a second light guide 3-2, and a third light guide 3-3. The first and third light guides 3-1 and 3-3 are formed in a cylindrical shape and are provided so as to extend in the width direction of the lamp. The second light guide 3-2 has a cylindrical portion 31 formed in a cylindrical shape and a strip portion 32 formed in a strip shape along the cylindrical portion 31, and the cylindrical portion 31 and the strip portion 32 are provided so as to extend in the width direction of the lamp.

[0016] The light source 2 includes a first light source 2-1, a second light source 2-2, a third light source 2-3, and a fourth light source 2-4. As shown in Fig. 1(b), the first light source 2-1 faces the incident portion 3-1a of the first light guide 3-1, the second light source 2-2 faces the incident portion 31a of the cylindrical portion 31 of the second light guide 3-2, the third light source 2-3 faces the incident portion 32a of the strip portion 32 of the second light guide 3-2, and the fourth light source 2-4 faces the incident portion 3-3a of the third light guide 3-3. The first, second, and third light guides 3-1, 3-2, and 3-3 are each provided with a step 33 that emits light L toward the outside of the lamp.

[0017] The tail lamp 1-1 is composed of a first light source 2-1, a first light guide 3-1, a second light source 2-2, and a cylindrical portion 31 of the second light guide 3-2. The stop lamp 1-2 is composed of a first light source 2-1, a first light guide 3-1, a second light source 2-2, a cylindrical portion 31 of the second light guide 3-2, a third light source 2-3, and a strip portion 32 of the second light guide 3-2. The turn signal lamp 1-3 is composed of a fourth light source 2-4 and a third light guide 3-3.

[0018] When the tail lamp 1-1 is turned on, the first and second light sources 2-1 and 2-2 are turned on, and the light L from the first and second light sources 2-1 and 2-2 is emitted from the cylindrical portion 31 of the first light guide 3-1 and the second light guide 3-2. When the stop lamp 1-2 is turned on, the first, second and third light sources 2-1, 2-2 and 2-3 are turned on, and the light L from the first and second light sources 2-1 and 2-2 is emitted from the cylindrical portion 31 and the band portion 32 of the first light guide 3-1 and the second light guide 3-2. When the turn signal lamp 1-3 is turned on, the fourth light source 2-4 is turned on, and the light L from the fourth light source 2-4 is emitted from the third light guide 3-3.

[0019] The outer cover 5 includes a first cover portion 51 made of a translucent material and a second cover portion 52 made of an opaque material. The color of the first cover portion 51 can be selected from red, brown, yellow, colorless, etc. The color of the second cover portion 52 can be selected from black, etc. The first cover portion 51 and the second cover portion 52 can also be formed by integral molding.

[0020] The first cover part 51 has a window part 53 that allows light L from the light source 2 that has passed through the inner lens 4 to pass outside the lamp, a leg part 56 that penetrates the inner lens 4, and a connection part 55 that connects the edge of the window part 53 to the leg part 56.

[0021] The second cover part 52 has a frame part 54 that covers at least a part of the edge of the window part 53. Here, the second cover part 52 is provided with a seal leg 58 around its periphery. The seal leg 58 is fitted into a seal leg receiving part 61 of the housing 6 to seal the periphery of the housing 6 and the outer cover 5, thereby forming a waterproof lamp chamber 7 inside both of them. Inside the lamp chamber 7, the light source 2, the light guide 3, and the inner lens 4 are arranged.

[0022] As shown in FIG. 3, an inclined surface 51a is formed on the back surface of the connection portion 55 to attenuate the leaked light L' from the light source 2 (light L from the first, second, and third light sources 2-1, 2-2, and 2-3 and the first and second light guides 3-1 and 3-2) that is emitted to the outside of the lamp through the leg portion 56. Here, the inclined surface 51a attenuates the leaked light L' from the back side of the inside of the lamp by changing the direction of the light L from the inside of the lamp toward the outside of the lamp (see FIG. 4(b)). In addition, the inclined surface 51a acts to make the front side of the inside of the lamp more visible than the back side when the lamp is turned off (see FIG. 6(b)). For this reason, it is preferable to adjust the surface angle θ of the inclined surface 51a from the horizontal plane according to the distance from the outside of the lamp to the fastening portion 57. Specifically, the surface angle θ can be made smaller as the fastening portion 57 is located further back inside the lamp. On the other hand, it is preferable to make the surface angle θ larger as the fastening portion 57 is located closer to the front side inside the lamp.

[0023] The inner lens 4 is made of a light-transmitting material, and the surface of the inner lens 4 is textured to make the lamp emit light evenly. The inner lens 4 has a protrusion 43 that is pressed against the back side of the outer cover 5, a fastening hole 41 that receives the leg portion 56 of the outer cover 5, and a thick portion 42 that thickens so as to protrude toward the back side of the connection portion 55 of the outer cover 5.

[0024] To fasten the inner lens 4 to the outer cover 5, a method can be adopted in which the convex portion 43 of the outer cover 5 is pressed against the back surface of the outer cover 5, the legs 56 are inserted into the fastening holes 41 of the inner lens 4, and the fastening portions 57 at the tips of the legs 56 are crimped. It is also possible to provide the fastening portions 57 with a lance shape and engage them with the edges of the fastening holes 41.

[0025] In the conventional configuration, as shown by the dashed line in Fig. 3, the connection portion 55 of the first cover portion 51 is formed with an R-shape that wraps around the corner portion 54a of the frame portion 54. On the other hand, in the configuration of the present disclosure, an inclined surface 51a is provided by cutting out a part of the R-shape. Also, in the conventional configuration, the inner lens 4 is provided with a substantially constant thickness at a position offset from the rear surface of the first cover portion 51 of the outer cover 5. On the other hand, in the configuration of the present disclosure, a thick portion 42 that protrudes toward the rear surface of the first cover portion 51 is provided.

[0026] Next, the operation of the vehicle lamp 1 configured as above when the tail lamp 1-1 and / or the stop lamp 1-2 are turned on / off will be described with reference to Figs.

[0027] As shown in Fig. 4(a), in the conventional vehicle lamp 11, when the tail lamp 1-1 and / or the stop lamp 1-2 are turned on, light L is emitted from the first and second light guides 3-1 and 3-2 and enters the fastening portion 57. The light L that enters the fastening portion 57 leaks (L') to the outside of the lamp through the window portion 53 of the outer cover 5. Therefore, as shown in Fig. 5(a), the fastening portion 57 is visually recognized as a point light.

[0028] On the other hand, as shown in FIG. 4(b), in the vehicle lamp 1 of the present disclosure, when the tail lamp 1-1 and / or the stop lamp 1-2 are turned on, light L is emitted from the first and second light guides 3-1 and 3-2 and enters the fastening portion 57. Here, the inclined surface 51a acts to attenuate the leaking light L' from the fastening portion 57. Therefore, as shown in FIG. 5(b), the leaking light L' from the window portion 53 of the outer cover 5 to the outside of the lamp is attenuated, and the point light of the fastening portion 57 becomes difficult to visually recognize. In addition, a part of the light emitted from the fastening portion 57 is attenuated by the thick portion 42 of the inner lens 4, so that the point light can be further difficult to visually recognize.

[0029] As shown in FIG. 6(a), in a conventional vehicle lamp 11, when the tail lamp 1-1 and / or the stop lamp 1-2 are turned off, the inside of the lamp can be seen through the window portion 53 via the path indicated by the dashed arrow, and therefore, as shown in FIG. 7(a), the fastening portion 57 can be seen from the outside of the lamp.

[0030] On the other hand, as shown in Fig. 6(b), in the vehicle lamp 1 of the present disclosure, even if the tail lamp 1-1 and / or the stop lamp 1-2 are turned off, the inside of the lamp can be seen through the window portion 53 along the path indicated by the dashed arrow, and therefore, as shown in Fig. 7(b), the fastening portion 57 is not visible from outside the lamp, and the back surface of the second cover portion 52 is visible from outside the lamp chamber. Also, the fastening portion 57 is shielded from the outside of the lamp by the textured thick portion 42, which further prevents the inside from being seen.

[0031] Therefore, according to the vehicle lamp 1 of this embodiment, it is possible to suppress spot lighting of the fastening portion 57 when the lamp is turned on, and to make the fastening portion 57 less visible from the outside when the lamp is turned off.

[0032] The present disclosure is not limited to the above-described embodiment, and the shape and configuration of each part can be appropriately modified without departing from the spirit of the present disclosure. [Explanation of symbols]
