Note that a configuration in which the outer lens 7 is omitted and the light source 2 is accommodated in a space formed by the light guide member 4 and the housing 3 may be employed.

FIG. 2 is a cross-sectional view showing the main part of the light guide member. FIG. 3 is an enlarged view of a main part when the light guide member is viewed from the light emitting direction.
As shown in FIGS. 2 and 3, the light guide member 4 includes an outer surface (first surface) 31, an inner surface (second surface) 32, a first light emitting unit 5, and a second light emitting unit 6 that face each other. And have. The inner surface 32 is a surface facing the housing 3. Light emitted from the light source 2 and incident on the light guide member 4 is totally reflected by the outer surface 31 and the inner surface 32 to guide the light guide member 4. The outer surface 31 is a surface (light emission surface) that emits light guided through the light guide member 4 to the outside.

  The first light emitting unit 5 emits the light L emitted from the light source 2 and guided through the light guide member 4 from the outer surface 31 as the first emitted light L1. The second light emitting unit 6 emits the light L emitted from the light source 2 and guided in the light guide member 4 from the outer surface 31 as the second emitted light L2.

  The first light emitting portion 5 includes a first cut forming portion 33 that emits the light L guided in the light guide member 4 from the outer surface 31 as the first emitted light L1. The first emitted light L1 forms a first light emission pattern LP1. The first light emission pattern LP1 by the first outgoing light L1 is the same as the pattern of the first cut forming portion 33.

  In a state where the light guide member 4 is viewed in a plan view (hereinafter simply referred to as a plan view) in the surface normal direction of the inner surface 32, the first cut forming portion 33 has a predetermined pattern. Specifically, the first cut forming portion 33 arranged a plurality of patterns in which a plurality of horizontally long hexagonal rings are connected in the first direction (left-right direction in FIG. 3) in the second direction (up-down direction in FIG. 3). Has a shape. Accordingly, the first emitted light L1 is a first light emission in which a plurality of patterns in which a plurality of horizontally long hexagonal rings are connected in the first direction (left-right direction in FIG. 3) are arranged in the second direction (up-down direction in FIG. 3). A pattern LP1 is generated.

In addition, the second light emitting unit 6 includes a second cut forming unit 34 that emits the light L guided through the light guide member 4 from the outer surface 31 as the second emitted light L2. In a state viewed from above, the second cut forming portion 34 has a pattern corresponding to the first cut forming portion 33, that is, the same pattern. Here, the same pattern means a pattern having the same size as well as the shape.
The second emitted light L2 forms a second light emission pattern LP2. The second light emission pattern LP2 by the second emitted light L2 is the same as the pattern of the first cut forming portion 33, that is, the first light emission pattern LP1 by the first emitted light L1.

  The first cut forming portion 33 is provided on the inner surface 32 of the light guide member 4. The first cut forming part 33 is composed of a plurality of first prism cuts (first cuts) 33a. The first prism cut 33 a functions as a prism that reflects a part of light guided through the light guide member 4. The light reflected by the first prism cut 33 a is emitted from the outer surface 31. Therefore, the emitted light from the first cut forming section 33, that is, the first emitted light L1 from the first light emitting section 5 is composed of a plurality of reflected lights from the first prism cut 33a.

  The second cut forming portion 34 is provided on the inner surface 32 of the light guide member 4. The second cut forming part 34 is composed of a plurality of second prism cuts (second cuts) 34a. The second prism cut 34 a functions as a prism that reflects a part of the light guided through the light guide member 4. The light reflected by the second prism cut 34 a is emitted from the outer surface 31. Therefore, the emitted light from the second cut forming section 34, that is, the second emitted light L2 from the second light emitting section 6 is composed of a plurality of reflected lights from the second prism cut 34a.

  In this embodiment, the 1st cut formation part 33 and the 2nd cut formation part 34 are arrange | positioned mutually shifted. Therefore, the first cut forming part 33 and the second cut forming part 34 intersect with each other.

In the intersection area KA, at least one of the first cut forming portion 33 (first prism cut 33a) and the second cut forming portion 34 (second prism cut 34a) is formed. In the present embodiment, only the first prism cut 33a is formed in the intersection area KA. In the intersection area KA, only the reflected light from the first prism cut 33a is emitted.

  According to this configuration, an increase in the amount of light emitted from the intersecting area KA can be suppressed as compared to the case where both the first prism cut 33a and the second prism cut 34a are formed in the intersecting area KA. Therefore, since the intersection area KA can be prevented from being partially brightened, a light emission pattern with less discomfort can be generated.

  Moreover, the brightness | luminance of the 1st emitted light L1 and the 2nd emitted light L2 can be adjusted with the shape or surface density (arrangement pitch) of the 1st prism cut 33a and the 2nd prism cut 34a, for example.

  In the present embodiment, the first prism cut 33a and the second prism cut 34a are, for example, conical cuts. As shown in FIG. 2, the first prism cut 33a and the second prism cut 34a each have an inclined surface 33a1 and an inclined surface 34a1 (hereinafter simply referred to as inclined surfaces 33a1 and 34a1) in a cross-sectional view. In this embodiment, the 1st prism cut 33a and the 2nd prism cut 34a have the same shape except the cut depth mentioned later differing. That is, the inclination angles of the inclined surfaces 33a1 and 34a1 are equal to each other, and the lengths of the inclined surfaces 33a1 and 34a1 are different from each other.

The inclination angle theta ₁ is defined by the angle between the reference surface M1 and the inclined surface 33a1 extending along the inner surface 32 of the light guide member 4, the inclination angle theta ₂ is defined by the angle between the inclined surface 34a1 and the reference surface M1 Is done.

The inclination angles θ ₁ and θ ₂ are set to 45 to 50 °, for example.
In the present embodiment, by setting the inclination angles θ ₁ and θ ₂ to 45 °, the component along the inner surface 32 of the light L guided through the light guide member 4 by the inclined surfaces 33a1 and 34a1 is applied to the outer surface 31. It can reflect in the orthogonal direction. Therefore, the first prism cut 33 a and the second prism cut 34 a of this embodiment effectively function as a prism that favorably emits the reflected light from the outer surface 31 of the light guide member 4.

  The cut shapes of the first prism cut 33a and the second prism cut 34a are not particularly limited as long as the light L guided through the light guide member 4 by total reflection can be refracted and emitted from the outer surface 31. Any shape may be adopted. For example, the cut shape of the first prism cut 33a and the second prism cut 34a may be a triangular pyramid shape or a high pyramid shape having a square shape or more (a quadrangular pyramid shape, a hexagonal pyramid shape, etc.). Further, the cut shape of the first prism cut 33a and the second prism cut 34a may be a pentahedron or a hexahedron having a trapezoidal cross section.

  Moreover, the 1st cut formation part 33 and the 2nd cut formation part 34 may be provided integrally with the inner surface 32, and are separate from the inner surface 32, ie, the 1st cut formation part 33 and the 2nd cut formation part. You may comprise by affixing another translucent member which formed 34 to the inner surface 32 side of the light guide member 4. FIG.

  When the thickness of the light guide member 4 is 2 mm, for example, the depths of the first prism cut 33a and the second prism cut 34a are set to 10 to 200 μm. In the present embodiment, the depth D1 of the first prism cut 33a is set to 30 μm, and the depth D2 of the second prism cut 34a is set to 15 μm.

  That is, in the light guide member 4 of the present embodiment, the depth D1 of the first prism cut 33a is greater than the depth D2 of the second prism cut 34a. Therefore, the inclined surface 33a1 of the first prism cut 33a has a larger area located inside the light guide member 4 than the inclined surface 34a1 of the second prism cut 34a. Therefore, the spot diameter of the reflected light by the first prism cut 33a is larger than the spot diameter of the reflected light by the second prism cut 34a.

FIG. 4 is a top view showing the main part of the light guide member. That is, FIG. 4 is a view of the light guide member 4 viewed from the outer surface 31 side.
As shown in FIG. 4, in the 1st cut formation part 33, the arrangement | sequence pitch P1 which arranges the some 1st prism cut 33a is 0.3 mm. That is, the interval between the adjacent first prism cuts 33a is P1. In the second cut forming section 34, the arrangement pitch P2 for arranging the plurality of second prism cuts 34a is 0.4 mm. That is, the interval between the adjacent second prism cuts 34a is P2.

  In the present embodiment, the arrangement pitch P1 of the first prism cuts 33a is shorter than the arrangement pitch P2 of the second prism cuts 34a. Therefore, the surface density of the first prism cuts 33a in the first cut forming part 33 is larger than the surface density of the second prism cuts 34a in the second cut forming part 34.

  In the vehicular decorative component 1 of the present embodiment, as shown in FIG. 2, the first emitted light L1 is composed of a plurality of reflected lights by the first prism cut 33a, and the second emitted light L2 is the second prism cut 34a. It is comprised by the some reflected light by. That is, the first emitted light L1 emitted from the first cut forming portion 33 is light that has a higher density than the second emitted light L2 emitted from the second cut forming portion 34 and includes a plurality of reflected rays.

  Therefore, in the vehicular decorative component 1 of the present embodiment, the first outgoing light L1 includes reflected light with a large spot diameter at high density, and the second outgoing light L2 includes reflected light with a small spot diameter at low density. Therefore, the luminance of the first light emission pattern LP1 by the first outgoing light L1 is higher than the luminance of the second light emission pattern LP2 by the second outgoing light L2.

  In the following description, the first emitted light L1 having relatively high luminance is referred to as bright pattern light L1, and the second emitted light L2 having relatively lower luminance than the first emitted light L1 is referred to as dark pattern light L2. To.
