Description
【考案の詳細な説明】 〈産業上の利用分野〉 本考案は自動車用前照灯に関するものである。[Detailed explanation of the idea] <Industrial application field> The present invention relates to an automobile headlamp.
〈従来の技術〉
最近、車体デザインとの関係から前照灯の正面
形状を、上下幅が極端に狭い横長形状に構成する
デザイン要求が多くなつて来ている。<Prior Art> Recently, due to the relationship with vehicle body design, there has been an increasing demand for a design in which the front shape of a headlamp is formed into a horizontally elongated shape with an extremely narrow vertical width.
そこで、仮に従来周知の前照灯をそのまま上下
幅が極端に狭い横長形状に構成したとすると、灯
体内にバルブから発生する熱がこもり易くなり、
特に灯体及び反射鏡の上部壁が熱的影響を受けて
前照灯としての耐久性に非常に乏しくなり、かと
いつて耐熱性の材料を使用すればコスト高になる
と言つた不具合を生じる。しかも、灯体の後方開
口部も必然的に小さくなるので、バルブの装着交
換が非常に困難となり、作業性も悪くなる等の不
具合を生じる。 Therefore, if a conventional well-known headlamp were to be constructed into an oblong shape with an extremely narrow vertical width, the heat generated from the bulb would easily accumulate inside the lamp body.
In particular, the lamp body and the upper wall of the reflector are affected by heat, resulting in very poor durability as a headlamp, and if heat-resistant materials are used, the cost will be high. Furthermore, since the rear opening of the lamp body is inevitably made smaller, it becomes very difficult to install and replace the bulb, resulting in problems such as poor workability.
〈考案が解決しようとする問題点〉

提供せんとするものである。<Problems to be solved by the invention> The present invention was made in view of the current situation, and even if the front shape is configured to be an oblong shape with an extremely narrow vertical width, the problem that occurs from the bulb inside the lamp body. There is relatively little heat buildup, the upper wall of the lamp body and reflector is not easily affected by heat, and the rear opening of the lamp body can be made large like a normal headlamp, making it easy to install and replace the bulb. It is an object of the present invention to provide an automobile headlamp that is easy to use.

ｂを形成することにより、背面カバー５延いては
その背面カバー５に着脱自在に取付けられるゴム
カバー８を大きく形成することが出来、その結果
バルブ７の装着交換作業が一層やりやすくなる。 The lamp body 1 is made of a resin material and has a flat, horizontally elongated front shape with a ratio of vertical width L: horizontal width M of about 3:10, and is formed into a substantially box-like shape at the front opening 2b. A lens seal groove 3a is formed around the lens seal groove 3a to fix the lens 4 in an airtight manner, a seal groove 3b is formed around the rear opening 2a to fix the rear cover 5 in an airtight manner, and a reflector 6 and a bulb are placed inside. 7 is installed to constitute a headlamp. The lens seal groove 3a formed in the front opening 2a of this lamp body 1 is formed surrounding the inside position of the front opening 2a, and the seal groove 3b formed in the rear opening 2b is formed in the rear opening 2b.
Form a surround at the outer position of. Seal groove 3 like this
By forming b, the rear cover 5 and the rubber cover 8 detachably attached to the rear cover 5 can be made larger, and as a result, the work of attaching and replacing the valve 7 becomes easier.
尚、ゴムカバー８には従来と同様、灯体１内に
外気を取り入れるための取入口９ａと、灯体１内
の熱気を排出させるための排気口９ｂとが開口形
成されている。 The rubber cover 8 is formed with an intake port 9a for introducing outside air into the lamp body 1 and an exhaust port 9b for discharging hot air from the lamp body 1, as in the conventional case.
そして、この灯体１の上下幅Ｌは前方開口部２
ａから後方開口部２ｂに向つて徐々に幅広く形成

の間の幅を、前方開口部２ａ側の幅L1より後方
開口部２ｂ側の幅L2を大きくL1＜L2形成するも
のである。 The vertical width L of this lamp body 1 is the front opening 2
It is formed gradually wider from a toward the rear opening 2b. That is, the width between the upper wall 1a and the lower wall 1b of the lamp body 1 is set so that the width L2 on the rear opening 2b side is larger than the width L1 on the front opening 2a side, L1 < L2. be.
反射鏡６はFRPなどの樹脂材を用いて、左右

６ｂ及び下部壁６ｃを平板状に形成してなり、そ
の後方開口部１０ａにバルブ７のソケツト１１を
着脱自在に取付ける。そして、この反射鏡６の上
下幅は前方開口部１０ｂから後方開口部１０ａに
向つて徐徐に幅狭く形成する。即ち、反射鏡６の
上部壁６ｂと下部壁６ｃとの間の幅を、前方開口
部１０ｂ側の幅H1より後方開口部１０ａ側の幅
H2を小さくH1＞H2形成するものである。又、反
射鏡６の上部壁６ｂには、前方開口部１０ｂから
バルブ７の直上位置まで奥深く切欠いて放熱部１
２を形成すると共に、その放熱部１２の直上位置
に放熱板１３を設置する。この様に、放熱部１２
を形成することにより、バルブ７から発生した熱
は反射鏡６の内部にこもることなく灯体１側へ素
早く循環排出されるようになる。 The reflecting mirror 6 is made of a resin material such as FRP, and has a reflecting surface 6a that is discontinuous in the left and right direction, and has an upper wall 6b and a lower wall 6c formed into a flat plate shape, and has a rear opening 10a with a bulb 7. Attach the socket 11 detachably. The vertical width of this reflecting mirror 6 is gradually narrowed from the front opening 10b toward the rear opening 10a. That is, the width between the upper wall 6b and the lower wall 6c of the reflecting mirror 6 is set to be smaller than the width H 1 on the front opening 10b side and the width on the rear opening 10a side.
This forms H 2 to a small value H 1 > H 2 . Further, the upper wall 6b of the reflector 6 is deeply cut out from the front opening 10b to a position directly above the bulb 7, and a heat dissipation part 1 is formed.
2, and a heat sink 13 is installed directly above the heat sink 12. In this way, the heat dissipation section 12
By forming this structure, the heat generated from the bulb 7 is quickly circulated and discharged to the lamp body 1 side without being trapped inside the reflecting mirror 6.
而して、灯体１内に反射鏡６を設置すると、灯
体１の後方開口部２ｂ側の空間１４ａ、即ち灯体
１の後方開口部２ｂ内周部分と反射鏡６の後方開
口部１０ａ外周部分とで構成される空間が、灯体
１の前方開口部２ａ側の空間１４ｂ、即ち灯体灯
体１の前方開口部２ａ内周部分と反射鏡６の前方
開口部１０ｂ外周部分とで構成される空間より大
きくなる。そして、外気はゴムカバー８の取入口
９ａから灯体１内に入り、空間１４ａから空間１
４ｂを通つてレンズ４の内面部分を通過し、再び
空間１４ｂを通り、バルブ７から発生する熱気と
共に空間１４ａを通つてゴムカバー８の排気口９
ｂから灯体１外へ排出され、灯体１内の空気が循
環対流する。 When the reflector 6 is installed inside the light body 1, the space 14a on the rear opening 2b side of the light body 1, that is, the inner peripheral portion of the rear opening 2b of the light body 1 and the rear opening 10a of the reflector 6. A space 14b on the side of the front opening 2a of the lamp 1, that is, an inner peripheral part of the front opening 2a of the lamp 1 and an outer peripheral part of the front opening 10b of the reflector 6. It becomes larger than the space it is composed of. Then, the outside air enters the lamp body 1 from the intake port 9a of the rubber cover 8, and from the space 14a to the space 1.
4b, passes through the inner surface of the lens 4, passes through the space 14b again, and passes through the space 14a together with the hot air generated from the bulb 7 to the exhaust port 9 of the rubber cover 8.
b is discharged to the outside of the lamp body 1, and the air inside the lamp body 1 is circulated and convected.

的影響を受け難くなる。<Effects of the invention> Since the automobile headlight of the invention is constructed in this way,
Even if the front face is formed into an oblong shape with extremely narrow vertical width, the space formed by the inner circumferential portion of the rear opening of the lamp body and the outer circumferential portion of the rear opening of the reflector can be enlarged. Circulation and convection of air inside the lamp body is now carried out smoothly, and as a result, there is relatively little heat buildup inside the lamp body from the bulb, and the upper wall of the lamp body and reflector is not affected by heat. It becomes difficult.
しかも、灯体の後方開口部を通常の前照灯と同
