Definitions
- the invention relates to a vehicle lamp with fluorescent tube, and in particular one Luminaire with at least one light source, a lens and a reflector the at least one light source is a fluorescent tube, the at least one an electrical lead wire on at least one of its two end portions having.
- Luminaires are generally known which have at least one fluorescent tube as the light source include. Such a lamp is described in DE 196 22 779. At this stand The technology is a contact of cold cathode tubes for lighting Gauges in a combination instrument that have a leadframe has, which receives the lighting elements, proposed, the Power supply to the tubes from the electronic control of the instruments is spatially separated.
- the object of the present invention is to provide a vehicle lamp which in Building more flexible solutions to design requirements and at the at the same time the number of elements in the lamp is minimal.
- the invention is based on the idea of the fastening device and the Summarize aperture device, i.e. the light source in the lamp on their Cover ends with a device that also serves as an attachment.
- the Luminaire according to the invention with at least one light source, a lens and a reflector in which the at least one light source is a fluorescent tube, the each have at least one electrical connection wire on at least one of their two Has end sections, is characterized by a fastening cover device, which connects the two end sections of the fluorescent tube to the reflector, so that the fluorescent tube is held by the reflector, and the two end sections covers the fluorescent tube so that they are not visible from the lens.
- the fastening cover device is preferably on the lens mirrored opposite side, so for a viewer who the Fluorescent tube looks through the lens, its end sections behind one mirrored surface ends and the connecting wires of the fluorescent tube invisible stay.
- An advantage of the vehicle lamp according to the invention is that the Installation of the lamp is simplified and therefore less expensive because fewer elements in the lamp are present.
- Fig. 1 is a lamp with its essential elements in perspective Representation shown.
- the lamp comprises at least one light source 1, which is behind a Lens 2 (Fig. 2) and is arranged in front of a reflector 3.
- the reflector 3 is reflects and serves the light that is emitted backwards by light source 1, throw back so that it can better yield the radiant power of the lamp emerges through the lens of the lamp to the front. Furthermore, due to the geometry the reflector 3 bundles the light in the desired manner.
- the light source 1 is a fluorescent tube. Fluorescent tubes are known as light sources in lights for motor vehicles. With the very different requirements that the fluorescent tubes in the Vehicle lights have to fulfill, the fluorescent tubes have a wide variety Forms on.
- the connecting wire is designated 5 in FIG. 1. It serves a pole of Lead fluorescent tube to the outside, so that an electrical voltage to the pole can be used to operate the fluorescent tube 1. Usually gets on each side of the fluorescent tube 1 a pole or a connecting wire 5 from the Fluorescent tube 1 led out.
- both poles the fluorescent tube are led out on only one side of the fluorescent tube, so that the fluorescent tube at one of its two end sections 4 two connecting wires 5th having.
- Fig. 1 is one of two end portions 4 of the fluorescent tube 1 with one Connection wire 5 shown. The connecting wire of the other pole of the fluorescent tube is not shown.
- the connecting wires 5 of the fluorescent tube 1 disturb the appearance of the lamp, if they are visible. A lot of efforts have therefore been made to hide them in the lamp. So far, however, this has always resulted in additional parts had to be installed as a panel in the lamp.
- a mounting cover 6 installed in the lamp 1 the connects the two end sections 4 of the fluorescent tube 1 to the reflector 3, so that the fluorescent tube 1 is held by the reflector 3.
- the invention Fastening cover device 6 thus serves as a fastening of the light source in the Lamp.
- the fastening cover device 6 covers the two End portions 4 of the fluorescent tube 1, so that the end portions 4 from outside the lamp through the lens 2 are not visible. This will make it Appearance of the lamp visually enhanced, and according to the task is Fastening cover device 6 according to the invention a greater scope in relation reached on the possibilities of the design of the lamp.
- the lamp according to the invention is shown in cross section in FIG. 2.
- the fastening cover device 6 with the lens 2 is fixed connected.
- the fastening cover device 6 has the shape of a cross section "W".
- To mount the fluorescent tube 1 in the lamp the fluorescent tube 1 in the reflector 3 positioned.
- the lens 2 with the integrated Fastening cover 6 placed on the reflector 3.
- the fluorescent tube 1 is so between the fastening cover 6 on the one hand and the (not shown) reflector held in the defined position.
- Fig. 2 so only from the side of the lens 2 of the lamp Fastening cover device 6 visible, but not the end section 4 of the Fluorescent tube 1.
- Fastening cover device 6 on its side opposite the lens 2 mirrored. This is the optical transition from the reflector 3, insofar as it is behind the Fluorescent tube 1 can be seen, and the fastening cover 6 above End section 4 of the fluorescent tube 1 is no longer visible from outside the lamp, and the appearance of the lamp is even more homogeneous.
