ために白熱電球を接続したばあいに加熱される内
部空気によつて圧力を増大させねばならない。 The problem of fogging of headlight diffusers and reflectors by condensed water vapor has not been satisfactorily solved to date, despite many proposals. A known solution consists in exchanging the air inside the headlamp with outside air via an opening. For this purpose, the pressure must be increased by the internal air, which is heated when an incandescent lamp is connected.

いて、十分な空気交換が行なうことができれば水
に対するシール性が不十分にされ、これに対して
水に対するシール性が十分であれば空気交換によ
つて前照燈内面の曇りが申し分なく阻止もしくは
除かれないということにある。 However, the difficulty of the above ventilation type is that in practice, if sufficient air exchange can be carried out, the seal against water will be insufficient, whereas if the seal against water is sufficient, the air exchange will not be sufficient. The problem lies in the fact that the clouding inside the lamp is not satisfactorily prevented or removed.

時に受ける向かい風に向かつて突出している。 In an embodiment of the invention, the headlamp has an air inlet in the lower section and an air outlet in the upper section, and a channel into which the air outlet opens is arranged in the side or rear section of the headlamp. The opening of this passage slopes downward toward the rear, and protrudes at the front edge toward the headwind encountered during driving.

囲に配置されている。 With the headlamp for a vehicle according to the invention, it is achieved in a simple manner that the inner surface of the headlamp is not clouded by condensed water and that no water penetrates into the interior of the headlamp. The present invention is based on the idea that a suction effect is produced at the air outlet, and this suction effect is caused by a headwind while the vehicle is running, and by a ventilation effect when the vehicle is stopped. having a mounted ventilation tube;
In contrast to vehicle lighting systems already known for centuries, the channel according to the invention is arranged in the lateral or rear region of the headlight.

Described in Section 8. The embodiment of the so-called casing-type headlamp according to claim 2 provides a ventilation device that can be adapted to conventional casings without significant outlay. If the headlight is constructed according to claim 3 or 4, the desired water protection is obtained even under unfavorable driving conditions. Most headlight casings are made from plastic. For this purpose, two
Two passage structures have been proposed.
次に図示の実施例につき本発明を説明する。 The invention will now be explained with reference to the illustrated embodiment.

1内に配置されている。 Most of the casing type headlights 10 are cap 1.
2, a diffuser plate 13 and a reflector 20 with an incandescent bulb 9, said casing 11 and cap 12 being made of plastic. The headlight 10 is fixed to the vehicle body 14 via a member not shown. An air outlet 16 is arranged in the upper side section of the casing 11, which opens into a channel 15 with a lower opening 17 and an upper opening 18. Since the upper opening 18 of the passage 15 is sloped downward toward the rear, the front edge 34 of the opening 18 protrudes toward the headwind received during driving. Reflector 20
is adjustably fixed within the interior 19 of the headlamp 10 and the air inlet portion 21 is positioned opposite the air outlet portion 16 in the casing 1 .
It is located within 1.

19内への空気入口部21を介した外気の流入を
生ぜしめる。 Since, during operation, outside air flows above the upper opening 18 of the channel 15, a suction effect is created which also creates a negative pressure in the air outlet 16, according to Bernoulli's theorem, so that the air flows into the interior 19.
flows to the outside. This results in an inflow of outside air into the interior 19 of the headlamp 10 via the air inlet 21.

てかすめられない。 The casing-type headlamp 30 in FIG. 2 has a casing 31 having a substantially rectangular shape. The tubular channel 15 is arranged in the upper lateral section 33 in such a way that the upper opening 18 of said channel 15 is located in the headwind encountered when driving and in this case the opening 18 faces the headwind. Since the edge 34 is located high, a head wind passes along the edge side. This creates a suction effect within the passage 15. The lower opening 17 is located in the shade of the headwind. The tube element 35 is arranged in a lower section 32 of the casing 31 located opposite the passage 15, and the two openings 37, 38 of said tube element 35 are not grazed by head winds.

and a tube element 35, in which case the end section of each tube piece 36 is slanted to prevent water entering the channel 15 or the tube element 35 from penetrating into the interior 39 of the casing 31. It's been cut out. The beveled end section of the tube opening into the channel 15 results in an increased velocity of the air flow in the channel reduction and thus a strong suction effect on the interior. Airflow is illustrated by arrows.

An air outlet, also formed as a tube piece 36, connects the interior 39 of the housing 41 with a channel 45, the upper opening 18 of which is located in the headwind and the lower opening 17 in the wind shade. are doing.
The air inlet part is designed as a tube piece 43, both of which are arranged on the underside of the housing 41. The suction and ventilation effects in the area of the upper opening 18 and the tube piece 36 are the same as described above.

A casing 51 made of plastic is shown in part, the tube piece 56 having an annular groove 57 located on the outside. A projection 58 protrudes from the channel 55, which is also made of plastic, and which is directed towards the inside of the locking body 5.
9, this stop 59 is radially outwardly elastic. When the casing 51 and the passage 55 are connected, the locking body 59 is snapped into the annular groove 57, so that the passage 5
5 and the casing 51 are releasably fixed to each other by a snap connection.
