本発明は、ＬＥＤバルブ本体の回動による配光調整を容易に行い、かつ、ＬＥＤバルブ本体と口金とを正確な位置決めをしてリフレクタ部の口金取り付け鍔部に固定できるようにした車両用灯具の配光調整方法及びその装置に関するものである。 The present invention is a vehicular lamp that facilitates adjustment of light distribution by rotating an LED bulb body, accurately positions the LED bulb body and the base, and can be fixed to the base mounting flange of the reflector. The present invention relates to a light distribution adjustment method and apparatus thereof.

ＬＥＤバルブ本体と口金の組み込み方法には、図６に示すものと図４に示すものとが知られている（特許文献１）。
図６に示すＬＥＤバルブ４３は、ベース本体１０の先端に、両側にＬＥＤ１４が取り付けられたＬＥＤ取付け部１１が一体に設けられたものである。この例では、ＬＥＤバルブ４３における略中間位置の円筒部２８に先端から口金２５が嵌めこまれ、この口金２５は、外側面からねじ２６がねじ込まれて円筒部２８に固定される。前記口金２５には、図５（ａ）（ｂ）に示すように、外周に３個の係止突片２９が設けられ、これらの係止突片２９がリフレクタ部１５の内周部の係止突片３０に嵌め込まれて互いに捻ると結合される。２７は、ゴムパッキンである。 As a method of assembling the LED bulb main body and the base, the method shown in FIG. 6 and the method shown in FIG. 4 are known (Patent Document 1).
The LED bulb 43 shown in FIG. 6 is integrally provided with the LED mounting portion 11 having the LEDs 14 mounted on both sides at the tip of the base body 10 . In this example, the base 25 is fitted from the front end into the cylindrical portion 28 in the substantially middle position of the LED bulb 43 , and the base 25 is fixed to the cylindrical portion 28 by screwing screws 26 from the outer surface. As shown in FIGS. 5(a) and 5(b), the mouthpiece 25 is provided with three locking protrusions 29 on its outer periphery. They are combined by being fitted into the locking projection pieces 30 and twisting each other. 27 is a rubber packing.

このような構成において、ＬＥＤバルブ４３のＬＥＤ１４による配光位置を予測して口金２５と円筒部２８の位置を決めてねじ２６で固定する。ＬＥＤ１４の位置を決めてリフレクタ部１５の口金取り付け鍔部２３に設けた係止突片３０に口金２５を図５（ａ）のように嵌め込み、図5（ｂ）のようにねじ込んで固定し配光を見る。このときの左右の配光がずれていて、水平などの目的の配光にならないときは、口金２５とリフレクタ部１５の固定を解除してＬＥＤバルブ４３を取り出し、ねじ２６を緩めて口金２５と円筒部２８の位置を調整する。この調整は、配光を見ながら行えないので、前記工程を何回か繰り返して水平などの目的の配光になるまで繰り返す。 In such a configuration, the positions of the cap 25 and the cylindrical portion 28 are determined by predicting the light distribution position of the LED 14 of the LED bulb 43 and fixed with screws 26 . After determining the position of the LED 14, the base 25 is fitted into the locking protrusion 30 provided on the base mounting flange 23 of the reflector section 15 as shown in FIG. see the light At this time, if the light distribution on the left and right is deviated and the target light distribution such as horizontal is not obtained, the fixation of the base 25 and the reflector part 15 is released, the LED bulb 43 is taken out, the screw 26 is loosened, and the base 25 is Adjust the position of the cylindrical portion 28 . Since this adjustment cannot be performed while observing the light distribution, the above steps are repeated several times until the target light distribution such as horizontal is obtained.

このように、口金２５と円筒部２８の位置を調整するためにねじ２６を緩めたり、締めたりして前記工程を何回か繰り返して目的の配光になるまで繰り返さなければならないという問題と、この工程の過程でねじ２６が緩んでベース本体１０が空回りの状態が発生すると、リフレクタ部１５の係止突片３０から口金２５の係止突片２９を解除できなくなるという問題があった。 In this way, there is the problem that the screws 26 must be loosened and tightened to adjust the positions of the base 25 and the cylindrical portion 28, and the above steps must be repeated several times until the desired light distribution is achieved. If the screw 26 is loosened during this process and the base body 10 idles, there is a problem that the locking projection 29 of the mouthpiece 25 cannot be released from the locking projection 30 of the reflector portion 15 .

これに対し、図４に示すＬＥＤバルブ４３では、両側にＬＥＤ１４が取り付けられたＬＥＤ取付け部１１とベース本体１０とは、別部材で構成し、ＬＥＤ取付け部１１の円筒部２８には、順次大径部２８ａと中径部２８ｂと小径部２８ｃが形成され、中径部２８ｂに後方から口金２５を段部３６に接するように回動可能に嵌合し、小径部２８ｃに接着層４２を介在してベース本体１０を圧入し固着する。すると、口金２５は、段部３６とベース本体１０に挟み付けられ、さらに、ベース本体１０の後方から貫通する２個のねじ孔３２に固定ねじ３３を螺合することにより、口金２５とＬＥＤバルブ４３が一体に固着される。この口金２５を図５（ａ）のように嵌め込み、係止突片２９と口金取り付け鍔部２３の係止突片３０を互いに回転係合すると、図５（ｂ）のようにＬＥＤバルブ４３とリフレクタ部１５が互いに固定的に取り付けられる。 On the other hand, in the LED bulb 43 shown in FIG. 4, the LED mounting portion 11 to which the LEDs 14 are mounted on both sides and the base body 10 are formed by separate members, and the cylindrical portion 28 of the LED mounting portion 11 is sequentially formed with larger sizes. A diameter portion 28a, a middle diameter portion 28b, and a small diameter portion 28c are formed. Then, the base body 10 is press-fitted and fixed. Then, the base 25 is sandwiched between the stepped portion 36 and the base body 10, and further, by screwing the fixing screws 33 into the two screw holes 32 penetrating the base body 10 from the rear, the base 25 and the LED bulb are connected. 43 are fixed together. When this base 25 is fitted as shown in FIG. 5(a), and the locking protrusion 29 and the locking protrusion 30 of the base mounting flange 23 are rotationally engaged with each other, the LED bulb 43 and the LED bulb 43 as shown in FIG. 5(b). Reflector portions 15 are fixedly attached to each other.

この例では、口金２５が中径部２８ｂにねじ込み固定するものではないから、口金２５をリフレクタ部１５に固定してＬＥＤバルブ４３を回動して配光調整してから、口金２５とＬＥＤバルブ４３が一体に固着される。そのため、図６のようにＬＥＤ取付け部１１が口金２５の嵌合孔４０内で空回りする恐れがない。もし空回りしても固定ねじ３３を固く締めなおせば、リフレクタ部１５の係止突片２９から固定を解除できなくなるという問題がない。 In this example, since the base 25 is not screwed into the medium diameter portion 28b and fixed, the base 25 is fixed to the reflector portion 15 and the LED bulb 43 is rotated to adjust the light distribution. 43 are fixed together. Therefore, there is no possibility that the LED mounting portion 11 will idle in the fitting hole 40 of the base 25 as shown in FIG. If the fixing screw 33 is firmly retightened even if it spins idle, there is no problem that the fixing from the locking protrusion 29 of the reflector portion 15 cannot be released.

そうすると、図６で示した方法と同様に、口金２５と円筒部２８の位置を調整するためにねじ２６を緩めたり、締めたりして前記工程を何回か繰り返して目的の配光になるまで繰り返さなければならないという問題と、この工程の過程でねじ２６が緩んでベース本体１０が空回りの状態が発生すると、リフレクタ部１５の係止突片３０から口金２５の係止突片２９を解除できなくなるという問題があった。 However, as shown in FIG. 3, in order to realize a so-called all-in-one model vehicle lamp in which the drive circuit 48 is built in the LED bulb main body 44, due to size restrictions, etc., the wiring board 46 of the LED 47 and the drive circuit 48 must In order to configure such a vehicle lamp, the LED bulb main body 44 integrates the radiator 44a and the top body 44b. It is desired to incorporate a wiring board 46 on which a circuit 48 is mounted.
In the case of the LED bulb main body 44 in which the radiator 44a and the top body 44b are integrated, the base 45 cannot be fitted from the tip of the LED bulb 43 by the method shown in FIG. As in the above method, it is required to fit the base 45 from the tip side of the LED bulb 43 .
Then, similar to the method shown in FIG. 6, the screws 26 are loosened and tightened to adjust the positions of the cap 25 and the cylindrical portion 28, and the above steps are repeated several times until the desired light distribution is obtained. If the screw 26 loosens during this process and the base body 10 idles, the locking projection 29 of the mouthpiece 25 cannot be released from the locking projection 30 of the reflector portion 15. I had a problem with it disappearing.

Then, the left and right LEDs 47 are exposed from the LED exposure windows 49 . Since the rotary sliding portion 57 of the top body 44b is a cylindrical body, the O-ring 64 is fitted into the O-ring groove 65, the fitting hole 56 of the base 45 is inserted into the top body 44b, and the end surface of the base 45 is connected to the radiator. It is brought into close contact with the stepped portion 58 of 44a. At this time, the outer peripheral surface of the rear end of the base 45 and the outer peripheral surface of the front end of the radiator 44a are flush with each other. When they are in close contact, the screws 54 are loosely screwed into the screw holes 55 to the extent that they lightly come into contact with the shallow grooves 73 of the rotary sliding portion 57 so that the mouthpiece 45 can rotate on the rotary sliding portion 57 . Since the screw 54 is loosely screwed into the shallow groove 73 of the rotary sliding portion 57, the mouthpiece 45 can be rotated in the rotary sliding portion 57 in the circumferential direction, but is displaced in the axial direction. never.

放熱器４４ａの端面から６角レンチなどの差し込み棒６６を差し込み、口金４５を回転摺動部５７で摺動しながら差し込み棒６６の先端を口金４５の嵌合穴６０の位置合わせをして差込み、ＬＥＤバルブ本体４４と口金４５を一体にする。
ＬＥＤバルブ本体４４と口金４５が一体になったら、図５（ａ）のように口金４５の係止突片５３を口金取り付け鍔部２３に形成した係止突片３０の隣り合う隙間に合わせてトップボディ４４ｂをリフレクタ部１５内に挿入し、図５（ｂ）のように停止位置まで回動して係止突片５３を係止突片３０に係止してＬＥＤバルブ本体４４をリフレクタ部１５の口金取り付け鍔部２３に固定する。

However, a notch portion 72 is provided in a portion other than the screw 54 so that a portion of the contact surface between the mouthpiece 45 and the radiator 44a is exposed as a mark display portion 70. As shown in FIG.

ＬＥＤバルブ本体４４をリフレクタ部１５に固定したら差し込み棒６６を嵌合穴６０と差し込み孔５９から抜いてＬＥＤ４７を点灯し、ＬＥＤバルブ本体４４を左方向又は右方向に回動して左右のＬＥＤ４７の配光が水平などの目的の配光となるように調整をする。
ＬＥＤバルブ本体４４の配光位置を調整したら、切欠き部７２のあるマーク表示部７０に口金４５とＬＥＤバルブ本体４４に跨る目印線を記入する。
目印線を付けたら、差し込み孔５９に差し込み棒６６を差し込み、記入した目印線を無視してＬＥＤバルブ本体４４を回動して口金４５の嵌合穴６０に差し込み棒６６の先端を差し込む。差し込み棒６６を差し込むと、口金４５とＬＥＤバルブ本体４４は一体になるので、ＬＥＤバルブ本体４４を口金４５とともに固定時と逆方向に回動して係止突片５３を係止突片３０から外す。
この状態でＬＥＤバルブ本体４４と口金４５をリフレクタ部１５の口金取り付け鍔部２３から取り外して、差し込み棒６６をＬＥＤバルブ本体４４から抜き取る。差し込み棒６６を抜き取ると、口金４５とＬＥＤバルブ本体４４は互いに回動可能になるので、先に記入したマーク表示部７０の調整時の目印線を合わせて、口金４５のねじ５４を回転摺動部５７の浅溝７３に固くねじ込み、口金４５とＬＥＤバルブ本体４４を一体にして図５（ａ）（ｂ）に示す順序で固定する。すると、ＬＥＤバルブ本体４４は、１回の操作で目的の配光となるように調整されて固定される。
このように、ＬＥＤバルブ本体４４をリフレクタ部１５に何回も取り付けたり外したりして配光を調整するような必要がなくなり、１回の操作で簡単に調整して取り付けができる。 After fixing the LED bulb main body 44 to the reflector part 15, the insertion rod 66 is removed from the fitting hole 60 and the insertion hole 59 to turn on the LED 47, and the LED bulb main body 44 is turned leftward or rightward to turn on the left and right LEDs 47. Adjust so that the light distribution becomes the desired light distribution such as horizontal.
After adjusting the light distribution position of the LED bulb main body 44 , a mark line extending over the base 45 and the LED bulb main body 44 is drawn in the mark display portion 70 having the notch portion 72 .
After marking the mark line, the insertion rod 66 is inserted into the insertion hole 59 , the LED bulb main body 44 is rotated ignoring the marked line, and the tip of the insertion rod 66 is inserted into the fitting hole 60 of the cap 45 . When the insertion rod 66 is inserted, the cap 45 and the LED bulb main body 44 are integrated, so that the LED bulb main body 44 is rotated together with the cap 45 in the direction opposite to that when fixed, and the locking projecting piece 53 is moved from the locking projecting piece 30. remove.
In this state, the LED bulb main body 44 and the base 45 are removed from the base mounting flange 23 of the reflector section 15 , and the insertion rod 66 is pulled out from the LED bulb main body 44 . When the insertion rod 66 is pulled out, the cap 45 and the LED bulb body 44 become rotatable relative to each other, so that the screw 54 of the cap 45 is rotated and slid while aligning the previously marked mark display portion 70 for adjustment. It is firmly screwed into the shallow groove 73 of the portion 57, and the base 45 and the LED bulb main body 44 are integrally fixed in the order shown in FIGS. 5(a) and 5(b). Then, the LED bulb main body 44 is adjusted and fixed so as to obtain the desired light distribution by one operation.
In this way, it is not necessary to attach and detach the LED bulb main body 44 to and from the reflector part 15 many times to adjust the light distribution, and the adjustment and attachment can be easily performed by one operation.

一旦取り付けたＬＥＤバルブ本体４４をリフレクタ部１５から取り外そうとして、ＬＥＤバルブ本体４４を回しても口金４５のねじ５４に緩みが生じて空回りするような事態が発生した場合、ＬＥＤバルブ本体４４を抜き取ることができても口金４５を外すことができなくなる。
このようなとき、差し込み棒６６を差し込み孔５９に差し込み、口金４５の嵌合穴６０と位置合わせをしてさらに押し込んでＬＥＤバルブ本体４４と口金４５を一体に固定してＬＥＤバルブ本体４４を回すことで口金４５の空回りなく取り外すことができる。 When trying to remove the once attached LED bulb body 44 from the reflector part 15, even if the LED bulb body 44 is turned, the screws 54 of the base 45 become loose and cause idle rotation. Even if it can be pulled out, the base 45 cannot be removed.
In such a case, insert the insertion rod 66 into the insertion hole 59, align it with the fitting hole 60 of the base 45, and push it further to fix the LED bulb main body 44 and the base 45 integrally, and turn the LED bulb main body 44. Thus, the base 45 can be removed without idle rotation.
