Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular fluorescent lamp each having a lamp cap at each end and a single-ended compact fluorescent lamp in which the lamp cap faces the carrier, and the fluorescent lamps are alternately linear. A segment of a linear lighting device mounted to a carrier, the segment comprising a substantially U-shaped profile having a base and legs, wherein the profile contains a power supply component for powering a fluorescent lamp, and
A segment of a linear lighting device comprising means for securing a mounting member adapted to the lampholder of a fluorescent lamp.
The invention also relates to a linear lighting device comprising such a segment.

[0002]

2. Description of the Prior Art Such a linear lighting device and its segments are known from EP-A-0510963. This linear illuminator makes it possible to evenly illuminate the carrier. In contrast to other linear lighting devices, which consist exclusively of tubular fluorescent lamps, this device holds the relatively dark end of the tubular lamp and the lamp cap, which is the light-free part, and the like. The nonuniformity of the illumination pattern caused by the lamp holder is prevented. Small fluorescent lamps with relatively high brightness compensate for the lack of light in these dark areas of other devices.
If the device known from EP 0514963 is arranged behind a transparent screen, this screen is also illuminated uniformly. For outdoor use and use in damp spaces, it is desirable for the power supply components to be able to be closed off from the environment in a watertight manner.

[0003]

The object of the invention is to have the possibility of sealing the power supply component with respect to the surroundings in a watertight manner,
And, nevertheless, to provide a segment of a linear lighting device of the type described at the outset, which is simple and allows easy installation of the linear lighting device with segments. It is also an object of the invention to have a linear lighting device adapted to such a segment.

[0004]

SUMMARY OF THE INVENTION According to the present invention, an open container containing a power supply component is substantially U of a segment.
This object is achieved by being housed in a V-shaped profile, the container being constructed in such a way that it can be combined with this profile in a watertight manner.

This segment can have a length selected from a plurality of lengths. The segment is, for example, about 12
It can be designed to accommodate a tubular lamp of about 36 W with a length of 0 cm and a small lamp. The segment then has a length of about 128 cm. Alternatively, the segment may accommodate one tubular lamp of about 58 W and a small lamp of about 150 cm in length. In this case it will be about 158 cm long. However, in other embodiments, the segments have multiples of one of these lengths, or have one length of tubular lamps plus one or several tubular lamps of other lengths. .
In a particular device, the type of segment used depends on the length of the carrier that comprises the linear lighting device.

Due to the fact that the segments have a considerable length and because each lamp should be powered through the connection of its lamp cap, the power supply components for the small and tubular lamps in the profile are It is practical to house it in the vicinity of the lamp. Thus, for example, in a segment with two or three tubular lamps, there will be two or three containers.

The segment according to the present invention is composed of containers,
And possibly allowing a cable connection between adjacent segments and then allowing the containers to be contained within the profile and also to seal them in a watertight manner to the profile. For connecting the lamp holder of the fluorescent lamp,
The cable may be led out of the profile in a watertight manner, for example. Alternatively, such a cable can be led out in a watertight manner from a wall, for example the end face of a container, and can extend through or along a profile towards the lampholder.

In the preferred embodiment, the profile has open ducts facing each other on the side of the base opposite the legs. These open ducts can together form a means for securing the mounting member. Thus, the mounting member will have a flange for this purpose having a first dimension less than the distance between the open ducts and a second dimension greater than this distance. The mounting member can be brought in its flange between the open ducts and can be connected to the ducts in the form of a bayonet giving an angular rotation of eg 90 °. Similarly, when supporting the screen in a support, the screen has similar flanges and is joined to the profile in a similar manner using open ducts. The lamp is mounted after the above screen in the completed device.

The cable or wire is led out of the mounting member so as to be coupled to the cable from the segment. However, when the mounting member covers the opening of the profile, for example, the cable from the mounting member is preferably coupled to the cable from, for example, the segment. If the profile opening around the cable is not yet sealed, the mounting member may optionally comprise an intervening seal, for example a sealing ring or a sealing disc.

In the preferred embodiment, the container is secured to a holder designed to be attached to the carrier of the linear lighting device. In this embodiment, the holder is attached to the carrier and the cable is led out in a watertight manner, for example through its end face, towards the adjacent segment using eg grommets. The holder may be a flat plate, for example a flat plate, but alternatively it may be a substantially U-shaped duct, for example having a base and legs. Such ducts have the advantage of having a greater rigidity than flat plates.

In a more particular embodiment, the holder has inwardly directed hooks at the ends of the legs which make a snap connection with a first ridge on the container. This attractive form is that the coupling already takes place when the container is put in its position in the holder. This is convenient if, for example, a device such as that provided along the roof edge requires repair and the container has to be replaced. However, if desired, the container may additionally be secured to the holder, for example by screws. For this purpose, a screw is inserted, for example, through a hole on the outside of the end face of the container. Then, it is not necessary to use any sealing means to maintain the water tightness between the screw and the container.

In one embodiment, the legs of the substantially U-shaped profile have an inwardly facing hooked edge with a second ridge on the container and a snap connection. An attractive form of this embodiment is that the coupling is accomplished by simply placing the container in the profile. This is convenient when the segments are assembled. It is also important in the case of mounting the device on the carrier or in the case of maintenance of already installed devices. In the process of returning the profile around the container fixed to the holder, the two hands are free to clamp the profile on the container, for example by means of screws, thus ensuring water tightness.

In one embodiment of the segment, the power feed component is housed in a component carrier that is secured to the split shaft at the wall of the container, which is contained in the container. The component carrier facilitates mounting of the component in the container. The parts can be fixed on the part carrier at any location and determined by their shape and size, for example by means of screws, hole rivets or the like. The component carrier can be fixed to the container without the wall of the container having to be penetrated for this purpose. Screws or, for example, pop rivets can easily be fixed in the gap. There is no need to drill holes in the container wall for this.
