Embodiment Construction

[0035] FIG. 1 shows a schematic cross-sectional view of an embodiment of a vehicle headlamp 10 according to the invention with a duct 11 independent of any other components inside the housing 5 of the headlamp 10. Component. This duct 11 has, for example, a borehole with a diameter between 5 mm and 7 mm, preferably 6 mm, and has an inlet 11 e associated with the hole 6 a of the ventilation unit 6 and an end outlet 11 s associated with the lower part 8 i of the reflector 8 constant cross-section (approximately 7mm to 10mm in diameter, preferably 8.3mm to 8.5mm).

[0036] The ventilation unit 6 is arranged on the vehicle interior "I", thus on the side opposite to the glass 4 forming the wall for closing the headlight 10 which gives the vehicle exterior "E".

[0037] As shown in the partial perspective view of FIG. 1A , the coupling between the inlet end 11 e of the duct 11 and the unit 6 is carried out on a cylindrical joint 6 b formed on the side 6 c of the unit 6 and integrat...

Abstract

The objective of the invention is to optimize gas through guiding gas to the glass of the front lamp and completely avoid the risk of the water entering the housing. The present invention provides a vehicle headlight with aeration system. According to the embodiment mode, the front lamp comprises a housing of the holding portion for holding light source, glass, a reflector, an air hole configured on the unit of the wall of the housing. The front lamp comprises a pipeline having the inlet and the outlet, the pipeline is connected with the inlet and the air hole, and the output of the pipeline is arranged at the position closed to the glasses. The air is transmited to the position of the lower portion closed to the glass.

Description

technical field [0001] The invention relates to a vehicle headlamp equipped with a ventilation system capable of preventing moisture condensation or significant heating of the air inside the housing in which the headlamp is accommodated. [0002] In a principal but not exclusive application, the invention relates to the field of motor vehicles, whose headlamps are sometimes exposed to wet conditions (rain, fog or washing) and which need to be able to quickly drain moisture entering the headlamp housing. In fact, the headlight housing cannot be completely sealed due to the temperature variations caused by the start-stop transition of the headlight causing pressure changes to be absorbed. Also, the temperature change at the standstill causes water vapor to condense on the glass. [0003] The headlight housing is therefore usually provided with air openings at the water shelter (abri de l'eau). However, it is still difficult to remove moisture and water entering the housing, an...
