VIBRATION RESISTANT AUTOMOTIVE FRONT LIGHTING LAMP

WIPO Patent Application WO/2015/052023

A3

A lamp for automotive front lighting and a vehicle headlight comprising the lamp are described, as well as a method of manufacturing the lamp. The lamp 10 comprises a base 12 for mechanical and electrical connection to an automotive headlight 50. A burner 14 is fixed to the base 12 and comprises a sealed transparent vessel 22. A first filament 34 is arranged within the vessel 22. A holding wire 30c is arranged within the vessel, and a baffle 40 is arranged proximate to the first filament 34 to partially shield light emitted from the first filament 34. The baffle 40 is fixed to the holding wire 30c. The transparent vessel 22 comprises a vessel wall including a cylindrical portion 24 surrounding the first filament 34. In order to obtain a lamp which may withstand vibration, a support member 38, 138, 238 is provided including at least a first part 39 fixed to the baffle 40 or to the holding wire 30c and a second part 43 which is in contact with the cylindrical portion of the vessel 22. The support member 38, 138, 238 comprises a flexible intermediate part 37 connecting the first and second parts, such that the baffle 40 or the holding wire 30c is supported resiliently against the vessel 22.
