  The best mode for carrying out the present invention will be described with reference to the drawings. The vehicular lamp according to the embodiment of the present invention is used as an automobile courtesy lamp. As shown in FIG. 1, this courtesy lamp 1 is a multifunctional lamp that is provided at an open end 4 inside a door 3 of an automobile 2 and illuminates a plurality of directions. In the present embodiment, a courtesy lamp attached to the door of the right rear seat will be described as an example.

  The courtesy lamp 1 includes a housing (lamp housing) 5 and an outer lens 6. The housing 5 has a substantially horizontally long rectangular parallelepiped shape and has an opening on the front surface 7 and the left side surface 8 thereof. A fitting frame 9 that borders the opening is formed at the periphery of the opening. Further, the outer lens 6 closes the opening of the housing 5, and an LED 10, which is one light source, is disposed inside the housing 5 as shown in FIG. 2. The LED 10 is turned on / off in conjunction with opening / closing of the door 3. The timing of turning off the LED 10 may be simultaneous turning off when the door 3 is closed, or may be delayed turning off that maintains the lighted state for a while after the door 3 is closed. The door 3 may be turned on / off in conjunction with the door 3 opening / closing lock (including an opening / closing lock using a remote control key), the distance from the owner of the automobile 2, and the like.

  A notch having substantially the same shape as the housing 5 extends from the door trim 11 to the door panel 12 adjacent to the door trim 11 (from the inner surface 23 of the door 3 to the side surface 25 of the open end). A hole 13 is formed, and the courtesy lamp 1 is inserted into the cutout hole 13 from behind. At this time, the fitting frame 9 is brought into contact with the peripheral edge of the cutout hole 13 so that the courtesy lamp 1 is not further inserted into the back. In this way, the courtesy lamp 1 is attached to the open end 4 of the door 3 of the automobile 2.

  The outer lens 6 of the courtesy lamp 1 includes an inward illumination unit (first illumination unit) 15 located at the upper part of the front surface 7, and a downward illumination unit (second illumination unit) 16 located at the lower part of the front surface 7. The rear illumination part (third illumination part) 17 located on the left side surface 8 is integrally formed. The front surface 18 of the outer lens 6 is formed as a flat surface, while the back surface 19 thereof corresponds to each desired irradiation direction (direction of the main optical axis) of the inward illumination unit 15, the downward illumination unit 16, and the backward illumination unit 17. The lens is cut. For example, as shown in FIG. 2, the back surface 20 of the inward illumination unit 15 is cut in a step shape so that the steps extending in the vertical direction of the courtesy lamp 1 are continuous in the horizontal direction. The back surface 21 is cut in a step shape so that the steps extending in the horizontal direction of the courtesy lamp 1 are continuous in the vertical direction. The rear surface 22 of the rear illumination unit 17 is prism-cut.

  In this way, the light from the LED 10 which is one light source is changed by the inner direction illumination unit 15, the lower direction illumination unit 16, and the rear direction illumination unit 17 having different lens cuts on the back surfaces 20, 21, 22 respectively. The light can be distributed in the direction.

  Specifically, as shown in FIG. 3, the inward illumination unit 15 has a main optical axis in a substantially vertical direction (the direction indicated by the arrow a) on the inner side with respect to the inner surface 23 of the door 3, and the inward illumination from the LED 10. The light incident on the portion 15 is distributed so as to be emitted toward the interior of the vehicle 2 (inward direction of the door 3) by the lens cut on the back surface 20, and the inward illumination portion 15 mainly emits the irradiation range A. To illuminate. Therefore, when the occupant opens the door 3 when getting on and off the vehicle 2, the inward illumination unit 15 illuminates the passenger compartment (rear seat and floor area) near the entrance on the right rear side of the vehicle where the door 3 is provided. Convenience when getting on and off. In addition, when the door 3 is opened more widely, the inward illumination unit 15 irradiates the rear of the vehicle, and functions as a signal lamp (viewed illumination) that makes the rear vehicle or person recognize the opening of the door 3. You can call attention to people. Further, if the LED 10 is turned off as described above, it is possible to support the behavior of the occupant until he / she settles on the seat after boarding.

  Further, the downward illumination unit 16 has a main optical axis obliquely downward (in the direction indicated by the arrow b) inward with respect to the inner surface 23 of the door 3, and light incident on the downward illumination unit 16 from the LED 10 is on its back surface 21. The light is distributed so as to be emitted toward the road surface (diagonally below the door 3) by the lens cut, and the downward illumination unit 16 mainly covers the irradiation range B. Therefore, when the occupant opens the door 3 when getting on and off the automobile 2, the downward illumination unit 16 illuminates the occupant's feet and the road surface, and the occupant can easily check the state of the feet and the road surface, so Can be used for

  Further, the rear illumination unit 17 has a main optical axis in a substantially parallel direction (direction indicated by an arrow c) on the rear side with respect to the inner surface 23 of the door 3, and the light incident on the rear illumination unit 17 from the LED 10 is on the back surface thereof. The rear illumination unit 17 mainly illuminates the irradiation range C by being distributed so as to be emitted in the rearward direction of the vehicle (the rearward direction of the door 3) while being diffused by the lens cut 22. Therefore, when the occupant opens the door 3 when getting on and off the automobile 2, the rear illumination unit 17 can function as a signal lamp that allows the rear car or a person to recognize the opening of the door 3. Further, when the door 3 is opened larger, it serves as a signal light for a car or a person on the side of the automobile 2. Since the rear illumination unit 17 is a signal lamp, the light from the rear illumination unit 17 can be changed to red light by lens toning of the rear illumination unit 17.
