This diffusion step 29 efficiently diffuses and reflects the irradiation light from the rear vehicle irradiated from the rear of the vehicle.

このような車両用灯具１０は、不図示のブレーキペダルが操作されることで、ＬＥＤ１５が発光し、この発光光がインナーレンズ１８の光学制御部２１により拡散制御される。そして、ＬＥＤ１５の発光光は、前面カバー１２に向けて進行され、前面カバー１２を透過して車両後方に向けて照射される。   In such a vehicular lamp 10, when a brake pedal (not shown) is operated, the LED 15 emits light, and this emitted light is diffusion-controlled by the optical control unit 21 of the inner lens 18. Then, the light emitted from the LED 15 travels toward the front cover 12, passes through the front cover 12, and is emitted toward the rear of the vehicle.

車両用灯具１０は、車両後方から光が照射された際に、インナーレンズ１８のダミー部２２の裏面側の拡散ステップ２９により、後方車両からの光を効率良く拡散・反射させることができる。また、ダミー部２２により、外部から電子部品１６および電子部品側バスバー２０が見えないように遮蔽することができる。   The vehicle lamp 10 can efficiently diffuse and reflect the light from the rear vehicle by the diffusion step 29 on the back side of the dummy portion 22 of the inner lens 18 when the light is irradiated from the rear of the vehicle. Further, the dummy part 22 can shield the electronic component 16 and the electronic component-side bus bar 20 from the outside.

次に、図６〜図９を参照して、本実施形態に係る車両用灯具１０に適用される透光部材の変形例について説明する。   Next, with reference to FIGS. 6-9, the modification of the translucent member applied to the vehicle lamp 10 which concerns on this embodiment is demonstrated.

As shown in FIG. 6, in the inner lens 31 of this modification, a reflective layer 32 is formed on the electronic component 16 side that is the back surface of the dummy portion 22 by painting or vapor deposition. The reflection layer 32 efficiently diffuses and reflects the irradiation light from the rear vehicle irradiated from the rear of the vehicle. The reflective layer 32 can shield the electronic component 16 and the electronic component-side bus bar 20 from the outside.

（第２変形例）
図７に示すように、本変形例のインナーレンズ３３は、透明に成形した光学制御部３４と、不透明や濃いクリア色に成形したダミー部３５と、を２色成形している。ダミー部３５は反射機能を有していないが、電子部品１６側に配置されることにより、外部から電子部品１６および電子部品側バスバー２０が見えないように遮蔽することができる。 (Second modification)
As shown in FIG. 7, the inner lens 33 of the present modification is formed in two colors: an optical control unit 34 molded in a transparent manner and a dummy unit 35 molded in an opaque or dark clear color. Although the dummy part 35 does not have a reflecting function, it can be shielded so that the electronic component 16 and the electronic component-side bus bar 20 cannot be seen from the outside by being arranged on the electronic component 16 side.

（第３変形例）
図８に示すように、本変形例のインナーレンズ３６は、ダミー部３７となる部位にシート状の遮蔽部材３８がモールド成形されている。この遮蔽部材３８は反射機能を有していないが、電子部品１６側に配置されることにより、外部から電子部品１６および電子部品側バスバー２０が見えないように遮蔽することができる。 (Third Modification)
As shown in FIG. 8, in the inner lens 36 of this modification, a sheet-like shielding member 38 is molded at a site that becomes the dummy portion 37. Although this shielding member 38 does not have a reflecting function, it can be shielded so that the electronic component 16 and the electronic component-side bus bar 20 cannot be seen from the outside by being arranged on the electronic component 16 side.

（第４変形例）
図９に示すように、本変形例のインナーレンズ３９は、灯室１３内に組み込まれるエクステンション部材４０の一部に光学制御部材４１が一体成形または嵌合されている。エクステンション部材４０は、蒸着、塗装或いは着色樹脂により成形されている。
