DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention generally relates to a lighting device, in particular to a signalling lamp for a vehicle, which consists of a lamp housing with a cover plate which at least in some areas is translucent.
BACKGROUND OF THE INVENTION
It is a general demand for such lighting devices to feature a decorative harmony with their immediate surroundings. Thus a beholder would dislike the sight of inattractive lamp housing surfaces and spaces or rather gaps between the lighting device and the adjacent wall. Additionally, there may result adverse effects on the air resistance of vehicles due to gaps in the outer surface of the vehicle body.
Various seals, mostly of the elastic type, are used for covering such spaces in the form of gaps or the like. These seals are held on the lighting device at least until the same is mounted on the corresponding mounting wall. The seals are generally fastened to the lighting device by gluing, clamping, clicking-in, by placing them on a rib or by foaming. The main function of these known seals, however, is to protect the areas or parts lying behind the housing against any penetration of dirt, water, aggressive agents etc.
DE 29 45 733 C2 describes a vehicle lamp with several bulbs. This vehicle lamp has a reflector body which essentially forms the lamp housing with several light chambers. A groove-type flange with a sealing ring foamed into the same extends on the outer edge of the reflector body which is adjacent to the cover plate. Apart from the fact that foamed seals in general will not impart an exactly decorative impression to the beholder, this particular version lacks a harmonious transition between the light and the metal part of the vehicle body. As compared with the outer edge of the light, the seal is placed relatively far back so that there remains a clearly visible joint between the light and the vehicle body.
DE 31 01 398 A1 likewise refers to a multi-chamber light for vehicles. This light is shut off towards the front by means of a cover plate composed of a plate and of a decorative frame. The decorative frame has two ribs placed towards the rear at different spacings with regard to the outer edge. In this area, a seal is inserted which in part is located in the area between the two ribs and which with the other part reaches over the outer rib. Due to this arrangement, the seal is kept in its position until the light is mounted. Afterwards, the metal of the vehicle body serves as a back rest. According to another embodiment the seal may also be the foamed-in type. In the described case, this seal is mainly to perform sealing functions. It does not serve any decorative purposes.
DE 34 05 962 C2 deals with a blinker inserted into a vehicle body. In this case, a rubber sealing lip is glued to a circumferential edge of the plastic housing. This sealing lip extends away from the plastic housing and rests with its lip edge against an adjacent metal part of the vehicle body. The main duty of this sealing lip is to protect an intermediate space between the lamp housing and the wall of the vehicle body against any penetration of water, dirt and aggressive agents. With respect to the outer edge of the vehicle body or of the light, the sealing lip is placed relatively far back which renders a relatively deep furrow. Thus, the decorative value of this sealing lip is not exactly good. Apart from that, gluing elastic seals is laborious and expensive.
DE 32 09 393 A1 describes a front blinker of automotive vehicles. A rubber seal is inserted into the area between the lamp and the adjacent area of the vehicle body. This seal is not closed in itself. The two end parts of the seal are provided with a hook engaging a shoulder of the housing from behind. Because of the tension produced in the longitudinal direction of the seal the same comes to rest against the blinker. In addition, two ribs form a groove engaged by an undercut section of the seal. The cross-section of the seal is U-shaped, one of the legs resting against the light and the other leg resting against the
