As shown in FIG. 1, an automotive lamp A is a lamp comprising a base part 1, a lamp part 2, and a cap 3 covered by the lamp part 2. The base portion 1 is composed of a base body 1a and a base 1b. The base body 1a radiates heat to the vertically opposed positions of the cylindrical fitting portion 5 provided at the base of the wedge 4 where the + electrode S and the −electrode N are disposed. An opening 5a is opened, and a fitting hole 5b is provided around the inner periphery of the end edge of the cylindrical fitting portion 5. On the other hand, the base 1b has a disk 6 having an outer diameter fitted into the fitting hole 5b. And a cylindrical portion 7 projecting in the direction of the wedge 4 at the center of the disk 6, and small holes 6 a penetrate the disk 6 at intervals of approximately 10 degrees over a range of required angles (110 degrees). The cylindrical portion 7 has a bolt insertion hole 7a at its center and a spring And a bolt 9 for setting a required mounting load on the spring 8 are housed, and a lead wire insertion groove 6b is formed in a circular arc shape on the disk surface of the disk 6 facing the small hole 6a with the bolt insertion hole 7a as a center. The ramp portion 2 includes a disc body 2a having the same diameter as the stepped portion 5c at the edge of the cylindrical fitting portion 5, and the wedge 4 along the axis of the disc body 2a. An oblong rectangular parallelepiped box 2b that protrudes from the opposite surface of the disk, and a disk surface of the disk 2a that contacts the disk 6 has a fitting pin 2c that fits in the same phase as the small hole 6a. A screw hole 2d for screwing the bolt 9 is screwed at the center of the disc body 2a, and an insertion hole 2e for inserting a lead wire is opened below the center of the disc body 2a. Along the axial direction of the disc 6 and the disc body 2a, In the space portion 2f hollowed out from the lower surface of the box 2b, an electric circuit 11 that electrically connects each LED 10 and each of the electrodes S and N is disposed. The cap 3 is made of a translucent cylinder that is closed with one end in the horizontal direction and the other end having two rows of heat radiation grooves 3a in the radial direction. Then, a heat radiation groove 3b having a required width is opened, and a thin flexible sheet-like reflector 12 is attached to the outer surface of the peripheral portion and the inner surface of the end portion on the surface opposite to the irradiation direction of the LED 10, The step portion 5c of the cylindrical fitting portion 5 and the fitting hole 3c that fits around the outer periphery of the disc body 2a are provided.

このようにして成る自動車用ランプＡは、ランプ部２の円盤体２ａの外周に透光面をＬＥＤ１０の照射方向に向けてキャップ３の嵌着孔３ｃが外嵌されて接着剤で接着されて成り、この状態で雌雄嵌着手段によりランプ部２にベース部１が着脱自在に嵌着される。すなわち、基盤１ｂが円盤６に開口された多数の小孔６ａの中央位置において、円盤体２ａの嵌着ピン２ｃに嵌着され、かつ、基盤１ｂの円筒部７に収納されるバネ８の外端をボルト９の頭部で押さえつつ、該ボルト９を円盤体２ａの中心に螺設したネジ孔２ｄに螺合させ、適宜な弾発力で円盤体２ａと基盤１ｂとを着脱自在に接合し、その状態で基盤１ｂの円盤６にベース部１の円筒嵌着部５の嵌着孔５ｂを外嵌し、接着剤で接着して成る。
したがって、図６に示す状態で、ベース部１を一方の指で押さえ、他方の指でバネ８の弾発力に抗してキャップ３を矢印方向アの左方へ引き抜けば、円盤体２ａの嵌着ピン２ｃが基盤１ｂの小孔６ａから外れ、矢印方向イの何れかの方向（所要照射方向）に回動して引き抜き力を解放すれば、バネ８の弾発力で矢印方向アの右方へ動作して嵌着ピン２ｃが小孔６ａに嵌着し、ウェッジ４における電極Ｓ、Ｎの位置に対して３個のＬＥＤ１０の照射方向を変更できることと成る。
このように、本考案の自動車用ランプＡは、各個の車載のソケット（図外）にウェッジ４を差し込んだとき、その車種によって照射方向が区々である場合でも、ソケットに対してランプ部２の姿勢を変更できるから、例えばナンバープレート（図外）を照明する場合などで、上からの照明でも下からの照明でも適宜な照射角度に、ＬＥＤ１０の照射光軸を簡単に対応できるのである。The thus configured automotive lamp A is formed by fitting the fitting hole 3c of the cap 3 on the outer periphery of the disk body 2a of the lamp portion 2 with the light-transmitting surface facing the irradiation direction of the LED 10 and bonding with an adhesive. In this state, the base part 1 is detachably fitted to the lamp part 2 by male and female fitting means. That is, the outer side of the spring 8 that is fitted to the fitting pin 2c of the disk body 2a and accommodated in the cylindrical portion 7 of the board 1b at the center position of the many small holes 6a that the board 1b is opened to the disk 6 While holding the end with the head of the bolt 9, the bolt 9 is screwed into a screw hole 2d screwed at the center of the disk body 2a, and the disk body 2a and the base 1b are detachably joined with an appropriate elastic force. In this state, the fitting hole 5b of the cylindrical fitting portion 5 of the base portion 1 is externally fitted to the disk 6 of the base 1b and bonded with an adhesive.
Therefore, in the state shown in FIG. 6, if the base portion 1 is pressed with one finger and the cap 3 is pulled out to the left in the direction of the arrow against the elastic force of the spring 8 with the other finger, the disc body 2a. If the fitting pin 2c is removed from the small hole 6a of the base 1b and is rotated in any direction (required irradiation direction) of the arrow direction a to release the pulling force, the spring 8 is elastically applied. The fitting pin 2c is fitted into the small hole 6a and the irradiation direction of the three LEDs 10 can be changed with respect to the positions of the electrodes S and N in the wedge 4.
Thus, when the wedge 4 is inserted into each vehicle-mounted socket (not shown), the automotive lamp A of the present invention has a lamp portion 2 with respect to the socket even if the irradiation direction varies depending on the vehicle type. Therefore, for example, when illuminating a license plate (not shown), the irradiation optical axis of the LED 10 can be easily adapted to an appropriate irradiation angle regardless of whether the illumination is from above or from below.

このほか、ベース部１での基盤１ｂとランプ部２での円盤体２ａとの嵌着に係る雌雄嵌着手段の他の実施例を説明すると、図７に示すように、円盤体２ａの嵌着方向の盤面に、嵌着軸心から放射状に所要角度の範囲（１１０度）に渡って山形状の突起１３を形成し、この盤面に対面する基盤１ｂの円盤６の盤面に、該突起１３と噛合するＶ溝１４を放射状に形成して係着する形態も提供される。  In addition, another embodiment of male and female fitting means for fitting the base 1b in the base 1 and the disc 2a in the ramp 2 will be described. As shown in FIG. 7, the disc 2a is fitted. A mountain-shaped protrusion 13 is formed radially on the disk surface in the wearing direction over a required angle range (110 degrees) from the fitting axis, and the protrusion 13 is formed on the disk surface of the disk 6 of the base 1b facing the disk surface. A form is also provided in which the V-grooves 14 meshing with the sword are radially formed and engaged.

本考案の自動車用ランプは、各個の車載のソケットの配置姿勢に対して、それに交差するＬＥＤの照射光軸を、きめ細かに広い範囲に渡って確実に位置決めできるから、振動に対して照射光軸が狂うことなく、広く各車種に対応できるので、自動車照明具業界に多大に貢献できる。  Since the automotive lamp of the present invention can reliably position the irradiation optical axis of the LED intersecting with each other on the mounting posture of each vehicle-mounted socket over a wide range, the irradiation optical axis against vibration Because it can handle a wide range of vehicles without going crazy, it can contribute greatly to the automotive lighting industry.
