Description

The invention relates to a tube lamp with at least one light source, in which a drawn rail is provided as a supporting element for the light source and other lighting components, which has an approximately semi-cylindrical cross-sectional shape that fits into a cylindrical protective tube made of glass or similar translucent material and with an intermediate wall is provided, which lies in the manner of the chord of a circle in a plane parallel to the Profilendkanten level and which serves as a mounting surface for lighting components, wherein the intermediate wall for firmly receiving fasteners, such as screws and / or rivets, longitudinal slots and / or longitudinal grooves having.

A tube lamp of the generic type is already off DE 9301903 U1 known. However, provided in this known bar lamp rail is suitable only for the use of a fluorescent tube as a light source. LED modules, which are also available in high-performance versions in recent times and are increasingly being used, can not be mounted on the known profile rail.

The invention has for its object to make the rail of a tube lamp of the generic type constructive so that it is equipped with LED modules and in the protective tube of the known fluorescent lamp against the equipped with a fluorescent tube profile rail is interchangeable, d. H. that you can easily turn parts of a fluorescent tube light into a fluorescent tube with LED modules.

This object is achieved according to the invention in that the rail is designed as a replacement support for alternative bulbs, especially for LED lights, and for their attachment instead of or in addition to a circular chord-like partition in the vicinity of at least one LED support strip for ribbon or rod-like LED Modules is provided.

The invention thus makes possible in a highly advantageous manner not only the replacement of a fluorescent tube with fluorescent tube against such with LED modules, but also in such a fluorescent lamp replacement of the equipped with a fluorescent tube rail against a rail, which is equipped with LED modules. It is not absolutely necessary to arrange the LED carrier strip in the vicinity of the circumference, which has the advantage, however, that there is still room for the accommodation of other lighting components and / or other lighting means inside the profile rail.

The embodiment according to claim 2 on the one hand gives the advantageous possibility of using the two carrier strips connecting, formed as a hollow web element as a cable guide and / or for fastening the end-side closure parts. In addition, it is possible to equip the carrier bars on one or both sides with LED modules and thus produce one and the same rail different lights with different light directions and light levels. The luminaire can thus be adapted in a very simple way to the particular requirements of the respective application. The special feature of this luminaire is the simplicity and multiple usability of the easiest way to produce suitable and can be fitted with the respective components rail.

The open at its ends hollow bar can also be used to hold the plug and / or screwing in fixing screws for the two end caps of the tube lamp to fix their position and secure against rotation.

The embodiment according to claim 3, which provides two light chambers with two separate, different light emission windows, considerably increases the application or application possibilities of the light tube, wherein in the embodiment according to claim 4 a meaningful supplement to claim 3 can be seen.

With an embodiment according to claim 5, the tube lamp can be optionally equipped with a fluorescent tube and / or with LED modules, so that additional variation options exist.

The arrangement of the receptacle for a fluorescent tube according to claim 6 facilitates the assembly of the different light sources and their power supply.

Claim 7 relates to an embodiment which, when equipped with a fluorescent tube and with LED modules, opens the possibility of choosing between two different light characteristics (eg colors).

The on the one hand diverging and on the other hand convergent main beam directions of mounted on the inside or outside surfaces of the carrier strips LED modules resulting from the mutually inclined carrier bars according to claim 2. This creates a higher light density, ie a brighter, more intense illumination on the converging emission side the irradiated area as on the divergent emission side, which is particularly in the use of the tube in Machine tools is of particular advantage, but also in outdoor lighting can be beneficial.

With reference to the drawings, the invention is explained in more detail below in a preferred embodiment.

It shows:

1 The details of a bar lamp according to the invention in an exploded isometric view;

1a a section Ia 1 slightly enlarged;

1b a cross section of a first embodiment;

2 a longitudinal section through the assembled tube lamp with the items from 1 ;

3 a cross section through a special embodiment of the tube lamp;

4 in isometric, interrupted representation, a bottom view of the tube lamp with inserted fluorescent tube;

5 the cross-section of another embodiment of the tube lamp with additional LED modules on an inserted support wall without protective tube and without the underside of the window opening occlusive transparent wall part;

5a the cross section of an embodiment in which the two carrier bars of the rail are equipped on both sides with LED modules;

5b the same cross section as 5a , but with two reflectors in the rail and

6 the cross section of an embodiment, as a combination of the 3 and 5 is trained.

The penlight shown in the drawings has an extruded profile rail as the load-bearing element on which all luminaire components are mounted 1 made of light metal, for example of an aluminum alloy or of a dimensionally stable, heat-resistant plastic. This profile has rail 1 how best of the 5 and 6 can be seen, a tube-like cross-sectional profile. A substantially circular, relatively thin-held profile wall 2 , which comprises about two-thirds of the circumference of a full cylinder and at two axially parallel profile edges 3 . 3 ' ends, is on its inside with several paraxial grooves 4 and ribs 5 provided in the form and arrangement symmetrical to a vertical plane of symmetry in the image 6 are. The two profile edges 3 and 3 ' lie in a direction perpendicular to the plane of symmetry 6 extending window level 7 in which between the two profile edges 3 . 3 ' also a lower light exit window 8th lies.

In two slightly below the horizontal median plane 9 lying grooves 4.1 and 4.2 the profile wall 2 is a mounting wall 10 stored, the upper side with an electrical components 12 carrying circuit board 11 is provided and the underside three LED carrier bars 13 . 14 and 15 for ribbon or bar-like LED modules 16 . 17 . 18 having.

While the middle LED support bar 13 centered to the plane of symmetry 6 is arranged so that the optical axes of the mounted thereon LED modules 16 with the plane of symmetry 6 coincide, have the two outer, symmetrical to the axis of symmetry 6 arranged carrier bars 14 and 15 each inclined support surfaces, so that the optical axes 19 respectively. 20 the mounted LED modules 17 respectively. 18 at an angle α of about 10 ° with the plane of symmetry 6 cut S in the same place.

How out 6 it can be seen in the light exit window 8th a wall gap closing and the profile wall 2 to a circle or cylinder completing wall part 21 can be used, which consists of a translucent material and thus does not optically close the light exit window. It is expedient here, this wall part with an optical glare protection, z. B. in the form of longitudinal grooves 22 od. Like. To provide. Here is the wall part 21 at its edges in each case with hook-like profile strips 55 . 56 provided, the form-fitting in profile grooves 57 . 58 engage, in which they are inserted from one end face.

While the mounting wall 10 with their pre-assembled LED modules 16 to 18 and the electrical components required for their operation 12 in this tube lamp is available for optional use and in the pre-assembled state axially into the rail 1 can be inserted, are in the upper half of the rail 1 on both sides of a radial hollow web 23 in symmetrical arrangement to the plane of symmetry 6 two with the hollow web 23 connected, preferably over the entire length of the rail 1 extending LED carrier bars 24 and 25 arranged, each of the bottom of an upper side open, equally long light chamber 26 respectively. 27 form and the two opposite mutually parallel support surfaces 28 respectively. 29 exhibit. Here are in the in 5 and 6 illustrated embodiment, only the upper support surfaces 28 the LED carrier bars 24 . 25 with LED modules 30 respectively. 31 stocked. The commercially available LED modules which are used here can be designed both as flexible bands and / or as flat rods.

Other designs that are well suited to be mounted on said support strips and easy to be attached, of course, can also be used.

In the execution according to 5a form the carrier strips 24 and 25 the bottom of another light chamber 40 extending outwards or downwards through the translucent wall part 21 closed and, moreover, laterally from the profile wall 2 is limited.

Depending on the field of application and application, it may be advantageous or expedient to make the individual LED modules separately switched on and off.

How out 5b can be seen, are also the LED carrier bars 24 and 25 with their support surfaces 28 . 29 inclined to each other so that the optical axes 32 respectively. 33 the LED modules arranged thereon 30 . 31 respectively. 38 . 39 with the plane of symmetry 6 each form an acute angle α of about 10 °. Accordingly, the optical axes run 32 and 33 the on the upper side carrier surfaces 28 the LED carrier bars 24 and 25 arranged LED modules 30 . 31 to the outside, ie diverging in the emission direction ( 3 ).

As 5a shows, but there is the obvious possibility, including the lower support surfaces 28 . 29 the LED carrier bars 24 . 25 each to be provided with LED modules whose optical axes 32 ' and 33 ' with the optical axes 32 respectively. 33 coincide and thus converge to each other, such that they are at the point S 'in the plane of symmetry 6 to cut. On the mounting wall 10 with the LED modules 16 to 18 can then be waived if necessary. To move the point of intersection S 'further outwards or downwards than in 5a shown, it requires only an increase in the inclination angle α. If necessary, it can be taken into account that the greatest light density and brightness prevail in the vicinity of the intersection point S '. The same applies with regard to the point of intersection S. Of course, it is necessary to determine the inclination angle α in advance depending on the circumstances and requirements of the site.

As is known, the LEDs, in the present case, the LED modules 30 . 31 such as 38 and 39 large light beam angle of over 90 °, so that it is in accordance with a lighting equipment of the tube according to 5a and 5b can be recommended in the grooves 4a and 4b the opposite profile wall sections 2 the profile rail 1 slightly curved reflector walls 51 . 52 to use, which reflects the falling light component of the LED modules 38 . 39 through the light exit window 8th to steer outside.

The upper openings of the light chambers 26 and 27 also form light emission windows 53 . 54 , however, by U-shaped profiled protective strips 34 . 35 are closed. These protective strips 34 . 35 consist of translucent material, eg. As acrylic glass, and they are in the light exit window of the light chambers 26 . 27 used and each designed as a glare protection by their peripheral wall elements 36 . 37 , preferably inside, with a groove structure od. Like. Are equipped. The outside openings of the light chambers 26 and 27 each form the light exit window for the LED modules 30 . 31 , To the protective strips 34 . 35 easy in the light chambers 26 . 27 they can be used in cross section so that they can be used with a slight self-holding voltage in them.

As the 4 There is also the possibility of finding in the relatively large cavity in 5a as a light chamber 40 is designated, instead of the wall part 10 with the LED modules 16 to 18 a fluorescent tube 41 with the corresponding holding device in the form of lamp sockets 45 and 46 to accommodate, as is the case with a known Stableuchte, which enjoys great popularity with the users, already the case. For such a combined tube light, both LED modules 30 and 31 as well as a fluorescent tube 41 As a light source, further applications, especially in the machine field can be developed.

In order to protect the electrical components of a fluorescent lamp of the generic or inventive type against harmful external influences, the rail with its electrical components, as in 3 represented by a translucent protective tube 42 enclosed, at both ends by means of fitted and releasably by means of screws on the end faces of the rail 2 fastened shutter disks 43 . 44 , which are preferably made of plastic, is sealed watertight.

At the in 3 embodiment shown is in the cavity of the rail 1 an electrical and electronic components for the operation of the LED modules 30 . 31 containing package 47 arranged at the bottom of one in the grooves 4 the profile wall 2 mounted support wall 48 is attached. In this embodiment, the rail is 1 only with those in the light chambers 26 and 27 on the carrier bars 24 and 25 mounted LED modules 30 and 31 equipped.

For replacing a profile rail 1 with fluorescent tube as light source against a profile rail equipped with LED modules 1 is only required at the two ends of the protective tube 42 the shutter discs 43 . 44 ( 1 ) and this at the new in the protective tube 42 inserted rail 1 to fix again. An advantage that makes the storage of both types of luminaires much easier and cheaper in practice.
