Description

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 vehicle lamp that facilitates light distribution adjustment by rotating the LED valve body, and allows the LED valve body and the base to be accurately positioned and fixed to the base mounting collar of the reflector portion. It relates to the light distribution adjustment method and the 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 incorporating the LED valve main body and the base, the one shown in FIG. 6 and the one shown in FIG. 4 are known (Patent Document 1).
The LED bulb 43 shown in FIG. 6 is one in which an LED mounting portion 11 to which LEDs 14 are mounted on both sides is integrally provided at the tip of the base main body 10. In this example, the base 25 is fitted from the tip into the cylindrical portion 28 at a substantially intermediate position in the LED bulb 43, and the base 25 is fixed to the cylindrical portion 28 by screwing a screw 26 from the outer surface. As shown in FIGS. 5A and 5B, the base 25 is provided with three locking projections 29 on the outer circumference, and these locking projections 29 engage the inner peripheral portion of the reflector portion 15. When they are fitted into the stop piece 30 and twisted with each other, they are connected. Reference numeral 27 denotes 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 position of the light distribution by the LED 14 of the LED bulb 43 is predicted, the positions of the base 25 and the cylindrical portion 28 are determined, and the light distribution position is fixed by the screw 26. The position of the LED 14 is determined, and the base 25 is fitted into the locking projection piece 30 provided on the base attachment flange 23 of the reflector portion 15 as shown in FIG. 5A, and screwed in as shown in FIG. 5B to fix and arrange the base 25. See the light. At this time, if the left and right light distributions are misaligned and the desired light distribution is not achieved, such as horizontally, the base 25 and the reflector portion 15 are unlocked, the LED bulb 43 is taken out, and the screw 26 is loosened to form the base 25. The position of the cylindrical portion 28 is adjusted. Since this adjustment cannot be performed while observing the light distribution, the process is repeated several times until the desired 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, in order to adjust the positions of the base 25 and the cylindrical portion 28, the screw 26 must be loosened or tightened, and the above steps must be repeated several times until the desired light distribution is achieved. If the screw 26 is loosened in the process of this step and the base body 10 is idle, there is a problem that the locking projecting piece 29 of the base 25 cannot be released from the locking projecting piece 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 valve 43 shown in FIG. 4, the LED mounting portion 11 to which the LEDs 14 are mounted on both sides and the base main body 10 are formed of separate members, and the cylindrical portion 28 of the LED mounting portion 11 is sequentially enlarged. The diameter portion 28a, the middle diameter portion 28b, and the small diameter portion 28c are formed, and the base 25 is rotatably fitted to the middle diameter portion 28b from the rear so as to be in contact with the step portion 36, and the adhesive layer 42 is interposed in the small diameter portion 28c. Then, the base body 10 is press-fitted and fixed. Then, the base 25 is sandwiched between the step portion 36 and the base body 10, and further, by screwing the fixing screw 33 into the two screw holes 32 penetrating from the rear of the base body 10, the base 25 and the LED bulb are valved. 43 is integrally fixed. When the base 25 is fitted as shown in FIG. 5A and the locking protrusion 29 and the locking protrusion 30 of the base mounting collar 23 are rotationally engaged with each other, the LED bulb 43 and the LED bulb 43 are engaged as shown in FIG. 5B. The 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 and fixed to the medium diameter portion 28b, the base 25 is fixed to the reflector portion 15 and the LED bulb 43 is rotated to adjust the light distribution, and then the base 25 and the LED bulb are adjusted. 43 is integrally fixed. Therefore, as shown in FIG. 6, there is no possibility that the LED mounting portion 11 runs idle in the fitting hole 40 of the base 25. If the fixing screw 33 is tightened tightly even if it spins idle, there is no problem that the fixing cannot be released from the locking projection piece 29 of the reflector portion 15.

ところが、図３に示すように、駆動回路４８をＬＥＤバルブ本体４４内に内蔵したいわゆるオールインワンモデルの車両用灯具を実現させるには、寸法制限などの理由から、ＬＥＤ４７の配線基板４６と駆動回路４８の基板を１枚にまとめる必要があり、このような車両用灯具を構成するには、ＬＥＤバルブ本体４４は、放熱器４４ａとトップボディ４４ｂを一体化し、このＬＥＤバルブ本体４４に、ＬＥＤ４７と駆動回路４８を搭載した配線基板４６を内蔵するものが望まれる。
このような放熱器４４ａとトップボディ４４ｂとを一体化したＬＥＤバルブ本体４４の場合、口金４５を図４で示した方法では口金４５をＬＥＤバルブ４３の先端から嵌合できないので、図６に示した方法のように、口金４５をＬＥＤバルブ４３の先端側から嵌合することが求められる。
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 valve main body 44, the wiring board 46 of the LED 47 and the drive circuit 48 are required for reasons such as dimensional restrictions. In order to form such a vehicle lamp, the LED valve main body 44 integrates the radiator 44a and the top body 44b, and the LED valve main body 44 is driven by the LED 47. It is desired that the wiring board 46 on which the circuit 48 is mounted is built-in.
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. 4, and is shown in FIG. It is required to fit the base 45 from the tip side of the LED bulb 43 as in the above method.
Then, in the same manner as in the method shown in FIG. 6, the screw 26 is loosened or tightened in order to adjust the positions of the base 25 and the cylindrical portion 28, and the above steps are repeated several times until the desired light distribution is achieved. When the problem of having to repeat and the state where the screw 26 is loosened and the base body 10 is idle in the process of this process occurs, the locking projecting piece 29 of the base 25 can be released from the locking projecting piece 30 of the reflector portion 15. There was a problem that it disappeared.

次に前記ＬＥＤバルブ本体４４の組み立てについて説明する。
配線基板４６の駆動回路４８に電源コード６１を接続し、駆動回路４８と端子部６２は、左右の放熱器４４ａの駆動回路収納凹部５２に収納し、配線基板４６は、左右のトップボディ４４ｂの基板嵌合凹部５１に嵌め込み、左右の放熱器４４ａとトップボディ４４ｂとを先端部と基端部の位置決め突起６７で位置合わせをして先端部と基端部の組立て孔６３にねじをねじ込んで一体に組み込む。すると、左右のＬＥＤ４７がＬＥＤ露出窓４９から露出する。前記トップボディ４４ｂは、回転摺動部５７が円柱体となるので、Ｏリング溝６５にＯリング６４を嵌め込み、口金４５の嵌合孔５６をトップボディ４４ｂに差し込み、口金４５の端面を放熱器４４ａの段部５８に密着させる。この時、口金４５の後端外周面と放熱器４４ａの前端外周面が同一面となる。密着したらねじ孔５５にねじ５４が回転摺動部５７の浅溝７３に軽く接する程度に緩くねじ込み、口金４５が回転摺動部５７で回動できる状態としておく。なお、ねじ５４が回転摺動部５７の浅溝７３に軽く接する程度に緩くねじ込まれているので、口金４５が回転摺動部５７で円周方向に回動できるが、軸方向に位置ずれすることはない。 Next, the assembly of the LED bulb main body 44 will be described.
The power cord 61 is connected to the drive circuit 48 of the wiring board 46, the drive circuit 48 and the terminal portion 62 are housed in the drive circuit storage recesses 52 of the left and right radiators 44a, and the wiring board 46 is housed in the left and right top bodies 44b. It is fitted into the board fitting recess 51, the left and right radiators 44a and the top body 44b are aligned with the positioning protrusions 67 at the tip and the base, and screws are screwed into the assembly holes 63 at the tip and the base. Incorporate into one. Then, the left and right LEDs 47 are exposed from the LED exposure window 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 face of the base 45 is a radiator. It is brought into close contact with the step 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 the same surface. When they are in close contact with each other, the screw 54 is loosely screwed into the screw hole 55 so as to lightly contact the shallow groove 73 of the rotating sliding portion 57, so that the base 45 can be rotated by the rotating sliding portion 57. Since the screw 54 is screwed loosely enough to lightly contact the shallow groove 73 of the rotary sliding portion 57, the base 45 can rotate in the circumferential direction at the rotary sliding portion 57, but is displaced in the axial direction. There is no such thing.

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。
前記リフレクタ部１５の係止突片３０を形成した端縁部は、前記ねじ５４の部分が被さる位置までねじカバー部６９として伸びている。しかし、前記ねじ５４の以外の一部に切欠き部７２を設けて口金４５と放熱器４４ａとの接触面の一部がマーク表示部７０となるために露出するようになっている。 Insert the insertion rod 66 such as a hexagon wrench from the end face of the radiator 44a, and insert the tip of the insertion rod 66 by aligning the fitting hole 60 of the base 45 while sliding the base 45 with the rotating sliding portion 57. , The LED bulb body 44 and the base 45 are integrated.
When the LED bulb body 44 and the base 45 are integrated, the locking protrusion 53 of the base 45 is aligned with the adjacent gap of the locking protrusions 30 formed on the base mounting flange 23 as shown in FIG. 5A. The top body 44b is inserted into the reflector portion 15, and as shown in FIG. 5B, the top body 44b is rotated to the stop position, the locking projection 53 is locked to the locking projection 30, and the LED bulb body 44 is the reflector portion. It is fixed to the base attachment collar 23 of 15.
The edge portion of the reflector portion 15 on which the locking projection piece 30 is formed extends as a screw cover portion 69 to a position where the portion of the screw 54 covers. However, a notch portion 72 is provided in a part other than the screw 54 so that a part of the contact surface between the base 45 and the radiator 44a becomes the mark display portion 70 and is exposed.

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 valve body 44 to the reflector portion 15, the insertion rod 66 is pulled out from the fitting hole 60 and the insertion hole 59 to light the LED 47, and the LED valve body 44 is rotated to the left or right to rotate the left and right LEDs 47. Adjust so that the light distribution is the desired light distribution such as horizontal.
After adjusting the light distribution position of the LED bulb main body 44, a mark line straddling the base 45 and the LED bulb main body 44 is written on the mark display portion 70 having the notch portion 72.
After attaching the mark line, insert the insertion rod 66 into the insertion hole 59, ignore the entered mark line, rotate the LED bulb main body 44, and insert the tip of the insertion rod 66 into the fitting hole 60 of the base 45. When the insertion rod 66 is inserted, the base 45 and the LED bulb main body 44 are integrated. Therefore, the LED bulb main body 44 is rotated together with the base 45 in the direction opposite to that at the time of fixing, and the locking protrusion 53 is locked from the locking protrusion 30. remove.
In this state, the LED bulb main body 44 and the base 45 are removed from the base attachment collar 23 of the reflector portion 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 base 45 and the LED bulb body 44 can rotate with each other. Therefore, the screw 54 of the base 45 is rotationally slid by aligning the mark line at the time of adjusting the mark display unit 70 described earlier. It is screwed firmly 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. 5A and 5B. Then, the LED bulb main body 44 is adjusted and fixed so as to obtain the desired light distribution in one operation.
In this way, it is not necessary to adjust the light distribution by attaching and detaching the LED bulb main body 44 to and from the reflector portion 15 many times, and the LED bulb main body 44 can be easily adjusted and attached 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。 If the LED bulb body 44 once attached is to be removed from the reflector portion 15 and the screw 54 of the base 45 is loosened even if the LED bulb body 44 is turned, the LED bulb body 44 is idled. 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 body 44 and the base 45 integrally and turn the LED bulb body 44. As a result, the base 45 can be removed without idling.
