Embodiment Construction

[0037] figure 1 The known headlight 1 is shown in detail in a front view, ie seen from the direction opposite to the main direction of illumination of the headlight 1 . figure 2 A cross-sectional view of the previous headlight is shown. The known headlight 1 has ventilation openings 2 in the lower part of its housing 3 and ventilation openings 4 in the upper part of its housing 3 . The terms lower and upper here refer to the orientation and layout of the headlight during its intended use in a motor vehicle, whereby the lower part refers to the part of the housing of the headlight 1 that is close to the road.

[0038] When the headlight 1 is used as intended, its orientation in space is indicated by the expressions x-, y- and z-direction. The x-direction is parallel to the longitudinal axis of the motor vehicle, the y-direction is parallel to the transverse axis, and the z-direction is parallel to the vertical axis of the motor vehicle. This also applies to the other figure...

Abstract

The headlight (1) has a housing (3) having a light exit opening, and a transparent cover plate (8) for covering the light exit opening. The ventilation opening (2) and vent (4) are arranged in the housing. The housing is provided with a hollow structure containing air inlet (13), air outlet (14) and a dimensionally stable pipe section arranged between air inlet and air outlet. The hollow structure is configured to guide the air stream flowing from ventilation opening to the vent within the housing.

Description

technical field [0001] The invention relates to a headlight for a motor vehicle comprising a housing with a light output opening, a transparent cover covering the light output opening, at least one ventilation opening and at least one exhaust opening in the housing. Background technique [0002] Such a headlight is known from DE10026487A1. [0003] Under certain climatic conditions, the headlight shades can condense from the inside. This occurs mainly when the headlights are cooling down after operation, if the moisture of the initially still hot air inside the headlights condenses on the cooled hood. Condensation will affect the appearance and transmission of the mask on the next run. [0004] Condensed masks should be dried again after the vehicle has driven a certain distance. In the known headlights, this is achieved by means of ventilation holes and exhaust openings in the headlight. The pressure difference between the bores, which occurs during driving, is used to ...
