- a luminaire is disclosed in DE-A-1.914.094.
- the above-described luminaire is used as a carrier of tubular discharge lamps, such as low-pressure mercury vapour discharge lamps. Such lamps are frequently used for general lighting purposes (for example in offices etc.), but also for special purposes, for example, for irradiating people, animals or plants.
- a thin-walled luminaire with a housing U-shaped in cross-section which is filled with cured foamed plastics material and having thin walls, for example sheet metal is very easy to handle owing to its comparatively low weight.
- An electric component required for operating a lamp to be fitted in the housing is understood to mean, for example, an electric component for stabilizing a discharge lamp (an electric stabilisation ballast), a starter or a capacitor.
- Electric wires are provided in the housing to connect the lamp and one or more of the components to a power line.
- the component(s) and the wires are embedded in the foam.
- a trough with a generally U-shaped cross-section in which the components and the associated electric wires are provided is the starting point.
- the U-shaped trough is provided with end partitions and is closed with a metal lid, whereafter, via an aperture in the lid or in the wall of the U-shaped trough foamed plastics material is injected into the space enclosed by said walls.

- a luminaire is described with a housing free of foamed plastics material in which housing sets of parallel connection wires in one plane are present. Said sets are connected to each other with help of special shaped switch- elements in a synthetic material housing. Said elements serve for the connection of the wires of the electric components in the luminaire with said sets of wires. The use of said elements during the manufacturing process is time consuming. Said elements are technically complicated and expensive.
- a luminaire defined in the opening paragraph is characterized in that for each lamp to be accommodated in the luminaire two of said wires are provided in parallel in the housing so as to extend in straight lines between the end partitions, and for each lamp the associated electric connecting means of said component or further components and of said fittings being positioned on at least one of the longitudinal axes of said two wires.
- a luminaire in accordance with the invention can be mass-produced in a simple way.
- the luminiaire is formed and dimensioned such that the manufacture of the U-shaped thin walled housing, the provision of the wiring and the components and fittings as well as the connection of the components and the fittings to the wiring can be easily integrated with the filling process of the housing with foamed plastics material in a high speed mechanization process. No special measures, such as a temporary fixation of the parallel wires or the components in the housing (for example during establishing the connection between the connecting means of the components and fittings with said wires) are necessary.
- connection with the lamp fittings are avoided.
- the fittings for the lamp are connected to the housing in such manner that an electric contact between the connecting means of the fittings and the wires is established.

- the connecting means of the components are, for example, in the form of thin metal horse-shoe- shaped piercing contacts (of a type, as described in, for example German Gebrauchsmuster 7508503).
- Such means are eminently suitable for use in a mechanized manufacturing process for high-speed interconnections of the components and wires.
- the junctions between the connecting means and the wire are wholly embedded in the foam. They are consequently little vulnerable to vibration etc.
- the use of a special cover plate of the housing, as is described in the said DE-A--1.914.094 is not necessary.
- the thin-walled U-shaped housing of the luminaire in accordance with the invention can be positioned around the components and the wires.
- the housing comprises means whereby fittings to accommodate the lamp are so connected to the housing that an electric contact with the wires is established.
- the wall of the housing is provided with special apertures of such a shape that the fittings can be locked in the apertures.
- the end partitions have double walls in which the fittings can be accommodated.
- the fittings to accommodate the lamp can be connected by a user, as separate components, in a detachable manner to the housing, for example by means of a snap connection.
- the fittings may alternatively be connected to the housing during the manufacturing process.
- the fittings may be connected, depending on the positions of the component, in comparatively randomly-selected positions (depending on the length of a lamp to be fitted in the luminaire) to the housing.

Description
- The invention relates to a luminaire for at least one tubular discharge lamp having an elongated thin-walled housing which is U-shaped in cross-section, said housing at its ends being provided with end partitions being positioned substantially transversely of the longitudinal axis of the housing, at least one component and electric wires for connecting said component to said lamp being present in the space limited by the wall of said housing and the end partitions, said space being filled with cured foamed plastics material in which the component and the wires are embedded, said housing further comprising means which cooperate with fittings for the accommodation of the lamp. Such a luminaire is disclosed in DE-A-1.914.094.
- The above-described luminaire is used as a carrier of tubular discharge lamps, such as low-pressure mercury vapour discharge lamps. Such lamps are frequently used for general lighting purposes (for example in offices etc.), but also for special purposes, for example, for irradiating people, animals or plants. A thin-walled luminaire with a housing U-shaped in cross-section which is filled with cured foamed plastics material and having thin walls, for example sheet metal is very easy to handle owing to its comparatively low weight. An electric component required for operating a lamp to be fitted in the housing is understood to mean, for example, an electric component for stabilizing a discharge lamp (an electric stabilisation ballast), a starter or a capacitor. Electric wires are provided in the housing to connect the lamp and one or more of the components to a power line. The component(s) and the wires are embedded in the foam. During the manufacture of the luminaire described in the above-mentioned DE-A-1.914.094 a trough with a generally U-shaped cross-section in which the components and the associated electric wires are provided is the starting point. Thereafter the U-shaped trough is provided with end partitions and is closed with a metal lid, whereafter, via an aperture in the lid or in the wall of the U-shaped trough foamed plastics material is injected into the space enclosed by said walls. Thereafter the liquid compound flows into the housing and cures to form a foamed solid material.
- Positioning the components in the U-shaped trough and wiring them as well as connecting the wires to the terminals of the components is a complicated and time-consuming procedure.
- In DE-A-26 56 973 a luminaire is described with a housing free of foamed plastics material in which housing sets of parallel connection wires in one plane are present. Said sets are connected to each other with help of special shaped switch- elements in a synthetic material housing. Said elements serve for the connection of the wires of the electric components in the luminaire with said sets of wires. The use of said elements during the manufacturing process is time consuming. Said elements are technically complicated and expensive.
- It is an object of the invention to provide a luminaire which is easy to handle and is of such a shape that its manufacture can be mechanized in a simple way so that it is suitable for mass- production.
- According to the invention, a luminaire defined in the opening paragraph is characterized in that for each lamp to be accommodated in the luminaire two of said wires are provided in parallel in the housing so as to extend in straight lines between the end partitions, and for each lamp the associated electric connecting means of said component or further components and of said fittings being positioned on at least one of the longitudinal axes of said two wires.
- A luminaire in accordance with the invention can be mass-produced in a simple way.
- The luminiaire is formed and dimensioned such that the manufacture of the U-shaped thin walled housing, the provision of the wiring and the components and fittings as well as the connection of the components and the fittings to the wiring can be easily integrated with the filling process of the housing with foamed plastics material in a high speed mechanization process. No special measures, such as a temporary fixation of the parallel wires or the components in the housing (for example during establishing the connection between the connecting means of the components and fittings with said wires) are necessary.
- In the luminaire according to the invention special bending procedures for the connection with the lamp fittings are avoided. The fittings for the lamp are connected to the housing in such manner that an electric contact between the connecting means of the fittings and the wires is established. The connecting means of said fittings and the connecting means of the components are positioned on the longitudinal axes of said wires.
- The connecting means of the components are, for example, in the form of thin metal horse-shoe- shaped piercing contacts (of a type, as described in, for example German Gebrauchsmuster 7508503). Such means are eminently suitable for use in a mechanized manufacturing process for high-speed interconnections of the components and wires. The junctions between the connecting means and the wire are wholly embedded in the foam. They are consequently little vulnerable to vibration etc. The use of a special cover plate of the housing, as is described in the said DE-A--1.914.094 is not necessary. During manufacture the thin-walled U-shaped housing of the luminaire in accordance with the invention can be positioned around the components and the wires. In addition, it is very easy to inject an accurate dose of the foam (as a liquid) in the space limited by the wall of the housing and the end partitions.
- The housing comprises means whereby fittings to accommodate the lamp are so connected to the housing that an electric contact with the wires is established. In a preferred embodiment for that purpose the wall of the housing is provided with special apertures of such a shape that the fittings can be locked in the apertures. For example the end partitions have double walls in which the fittings can be accommodated.
- The fittings to accommodate the lamp can be connected by a user, as separate components, in a detachable manner to the housing, for example by means of a snap connection. However, the fittings may alternatively be connected to the housing during the manufacturing process.
- In one embodiment of a luminaire in accordance with the invention the fittings may be connected, depending on the positions of the component, in comparatively randomly-selected positions (depending on the length of a lamp to be fitted in the luminaire) to the housing. In a practical embodiment the housing is of such a shape that when providing the fittings at the ends near the end partitions, several tubular low-pressure discharge lamps of a standardized length can be accommodated in the luminaire. In a special embodiment the housing serves as a mounting channel for a pendant luminaire.
- In a luminaire in accordance with the invention the first electric wire is interrupted between connecting means of a first component, such as the electric stabilisation ballast. In a practical embodiment, to accommodate a second component being a unit (for example consisting of plastics material) provided with metal current connecting pins as means for connection to a power supply mains of, for example, the ballast and the fittings, the first wire is also interrupted in a different place between the two current connecting terminals of said unit. Lamps which can start without the aid of a starter are suitable for such a luminaire. To accommodate many low-pressure mercury vapour discharge lamps for general lighting purposes there is, however, in one embodiment an interruption in the second wire between current connecting means of a starter. The starter is, for example, provided in a special unit, the said interruption being located between current connecting means of said unit for the electrical and mechanical connection to the second wire. These current connecting means are located on an imaginary line which coincides with the second wire.
- The invention will now be further described by way of example with reference to the accompanying drawing which shows an embodiment of a luminaire in accordance with the invention.
- In the drawing:
- Fig. 1 is a perspective view of a luminaire and
- Fig. 2 shows diagrammatically the wiring and the associated components in a luminaire in accordance with Fig. 1.
- The luminaire shown in Fig. 1 comprises an
elongate housing 1 which is a trough with a U-shaped cross-section. Thewall 2 of the housing is made from pre-lacquered steel or aluminium and in a practical embodiment is approximately 0.2 mm thick.

end partitions fittings housing 1 the current supply means 23, 24, 25 and 26 located in the fittings are folded to a U-shape. When they are positioned in the final partitions an electric connection is made to the ends of thewires - The current connecting
means wire 11. -
Wire 10 has only one interruption, namely between theterminals starter 30 with associated anti-interference capacitor (not shown), see Fig. 2, which in a practical embodiment is included inunit 17. Theterminals wire 10. Also the current supply means 3 (of Fitting 8) and 25 (Fitting 9) are located on said imaginary line. The situation described in the foregoing is shown diagrammatically in Fig. 2. - It should be noted that in a luminaire which is suitable to accommodate, for example, two lamps, four parallel wires are provided in the housing. The housing then comprises two electric stabilisation ballasts, two starters etc.
- A luminaire as shown in Fig. 1 can be made starting from two substantially parallel-extending electric wires formed from a copper core having a plastic material insulation. The length of the wires substantially corresponds to the length of the housing of the luminaire. The wires are thereafter connected in the
end partitions unit 17 which comprises thepins starter 30 is positioned on the wires and the different portions between the connectingmeans - Thereafter the trough-shaped thin-walled housing is positioned so that it accommodates the wiring and the components, the wall of the ballast bearing substantially on three sides of the housing. Thereafter the end partitions are connected to the
wall 2 of the housing, whereafter the housing is turned until the open side faces an injector of a foaming machine. The foam is injected in a measured quantity in liquid form, the injector moving along substantially the full length of the housing. After a comparatively short period of time the liquid material expands and cures, a uniform cellular structure being obtained. The foam has then adhered to the wall of the housing and to the components located therein. Also the wiring is wholly embedded in the foam. The density of the foam (consisting of polyisocyanurate foam in a practical embodiment) is comparatively low and its weight is correspondingly low. This procedure results in a luminaire having a housing which has a high degree of rigidity. - The luminaire may be fastened to a ceiling or a wall, for example by means of a metal support in the form of a plate. Said support may be fastened to a ceiling, for example by means of a screwed connection. The open side of the housing having a U-shaped cross-section faces the support and is fastened thereto in a detachable manner, for example by means of a snap connection.
