Description

Technical field

The invention relates to a lamp insert module for use in a lamp housing of a tunnel lamp.

State of the art

Tunnel lights for illuminating tunnel systems are well known. The term tunnel lamp is understood to mean a lighting unit with at least one lamp (illuminant) and further technical components such as, for example, a lamp housing, electrical cables, holding or fastening elements, etc. Such tunnel lights are usually arranged on the tunnel ceiling or on the side tunnel walls. To illuminate the single-lane or multi-lane tunnel lane, a plurality of such tunnel lights are preferably provided along the tunnel lane to be illuminated.

Conventional tunnel lights, as exemplified in the DE 203 17 146 shown, a closed luminaire housing attached to the tunnel ceiling via a support with a frame for a transparent cover. The cover frame is releasably connected to the lamp housing in a conventional manner via a pivot bearing and a closure. The light tube within the light housing is partially enclosed by a reflector, so that the light generated by the light tube is reflected by the transparent cover in the direction of the tunnel roadway. While the luminaire housing is generally extremely robust and long-lasting due to the extreme stresses such as dust whirled up by vehicles, spray, fluctuating temperatures, moisture, etc., the service life of the illuminant arranged in the luminaire housing is relatively short. Therefore, the tunnel lights have to be serviced at regular intervals and bulbs or even the entire light unit must be replaced. Another disadvantage is that the lamps used have a relatively high energy consumption.

In order to simplify the maintenance and the replacement of lamps in a tunnel lamp, it has been proposed in the prior art to equip the tunnel lamp with swiveling inserts. Of the DE 7 342 337 U1 For example, a tunnel luminaire with fluorescent tubes can be seen, which has a luminaire housing in which swivel-out inserts are arranged, and these carry all components required for operating the luminaire, such as ballasts, starters, sockets, reflectors and illuminants or fluorescent tubes. Although maintenance is simplified here by swiveling out the insert, on the one hand the illuminants used are very maintenance-intensive, on the other hand they have a high energy consumption. Another disadvantage is that these tunnel lights cannot be converted to energy-saving light units.

In the recent past, however, light sources formed by a large number of light emitting diodes or LEDs ("light emitting diodes") have been used more and more in tunnel luminaires. These are low-maintenance and have a lower energy consumption compared to alternative lamps such as fluorescent tubes. From the DE 20 2017 10 636 U1 Tunnel luminaires are already known in which light-emitting diodes or so-called LEDs ("Light Emitting Diodes") are used as illuminants. The tunnel luminaire or linear luminaire consists of a preferably elongated luminaire housing and a transparent housing cover that can be detachably connected to the luminaire housing. In the interior of the housing, a carrier module without heat-conducting contact to the luminaire housing is also accommodated, on the side facing the housing cover, illuminants in the form of light-emitting diodes are arranged. A disadvantage of these tunnel lights is that, due to their design, they cannot be installed in existing tunnel lights, ie retrofitting existing tunnel lights is therefore not possible. Rather, the existing tunnel lights have to be removed from the tunnel ceiling or side tunnel walls before the new, elongated, and several energy-saving illuminant tunnel lights can be installed.

Presentation of the invention

On the basis of the prior art set out, the object of the invention is to provide an illuminant insert module for a tunnel luminaire, which is suitable for retrofitting or retrofitting existing tunnel lights and is easy to replace. This object is achieved by the lamp insert module according to claim 1.

The present invention provides a lamp insert module for use in a luminaire housing of a tunnel luminaire, consisting of at least one cooling unit, which is formed by bending from a metallic flat material and forms a heat sink, the cooling unit having a rectangular, flat base section with an upper and lower side and at least one has at a bending edge of the bottom section adjoining and projecting from the bottom side section. In an alternative embodiment, the cooling unit has a rectangular, flat bottom section with an upper and lower side as well as rectangular, flat side sections adjoining at least two bending edges of the bottom section running parallel to one another and projecting from the underside. Furthermore, the cooling unit has at least one contact section which adjoins the side section, is spaced apart and runs parallel to the bottom section. The lamp insert module further consists of at least one light unit comprising a plurality of light-emitting diodes, which is arranged on the top of the bottom section of the cooling unit and is thermally conductively connected to the bottom section of the cooling unit, and at least one plate-shaped holding element for fastening the lamp insert module to the lamp housing of the tunnel lamp. The at least one holding element is arranged on the top of the bottom section of the cooling unit and has at least one opening, the at least one lighting unit being received in the opening and being enclosed in a frame-like manner by the holding element.

The term "luminaire housing" used in the present text refers to conventional housings made of preferably dimensionally stable, folded metal sheet, in particular stainless steel sheet, with high mechanical strength and corrosion resistance. The luminaire housing on the side facing the tunnel carriageway is covered flush with the housing by a pivoting holding frame, preferably made of stainless steel, the holding frame being designed to accommodate a cover made of transparent material, in particular a glass or plexiglass pane. To attach the luminaire housing to a tunnel ceiling or to the side tunnel wall, several fastening lugs or brackets or fastening brackets are provided on the luminaire housing.

The lamp insert module according to the invention is used in a luminaire housing of a tunnel luminaire and is associated with the advantage that existing tunnel luminaires can be converted in a simple and inexpensive manner. The special design of the lamp insert module means that it can be installed in the existing lamp housing of a tunnel lamp. The device carrier located in the luminaire housing, e.g. Device carrier of a HIT / HST luminaire, and the existing reflector lamp module removed and replaced by a mechanically identical device carrier and at least one lamp module. This has the great advantage that existing tunnel luminaires, which are equipped with an equipment rack, a reflector and outdated lamps, e.g. Fluorescent tubes, high-pressure discharge tubes, etc., are equipped with illuminant insert modules with at least one light unit comprising a plurality of light-emitting diodes or the associated equipment carrier can be replaced. Another advantage can be seen in the fact that when a retrofit is carried out, the entire tunnel luminaire does not have to be replaced, but only the device holder and the reflector-illuminant module accommodated in the luminaire housing. As a result, retrofitting of existing tunnel luminaires with the lamp insert module according to the invention or the associated device carrier can be carried out cost-effectively. The simple modular design of the lamp insert module also enables a quick, tool-free exchange of either the entire lamp insert module or individual components thereof in the event of a fault or wear.

The light sources in the form of light-emitting diodes are advantageously mounted on a printed circuit board. In a preferred embodiment, a plurality of light-emitting diodes, preferably grouped, are arranged on a printed circuit board and, together with the associated corresponding electrical connection options and, if appropriate, electronic components required for controlling the light-emitting diodes, form a so-called lighting unit. According to the invention, a plurality of light-emitting diodes means 8 to 32, preferably 12 to 20 individual light-emitting diodes per lighting unit. The light-emitting diodes are preferably arranged as light-emitting diode groups on the printed circuit board, a light-emitting diode group preferably comprising four light-emitting diodes. In a preferred exemplary embodiment, a lighting unit has sixteen light-emitting diodes, which are divided into four light-emitting diode groups. It goes without saying that the number of light-emitting diodes per group and / or module and the number of modules per se can be chosen arbitrarily in order to achieve a desired one To achieve light output or lumen output. The LEDs can also be dimmable.

A plurality of such lighting units are preferably interchangeable, spaced apart and thermally conductively connected to the top of the bottom section of the cooling unit, preferably by means of releasable connecting means such as screws. In order to facilitate the fastening of the lighting units to the base section, corresponding drill holes suitable for attaching the lighting units, preferably with an internal thread, can already be provided on the base section. Each of the lighting units is preferably fastened to the base section several times, as a result of which a uniform contact pressure of the lighting unit is achieved on the base section. It is only through the even contact pressure of the lighting unit on the floor section that it is ensured that a homogeneous and at the same time effective heat dissipation can take place. However, it would also be conceivable to attach the lighting units in a non-detachable and thermally conductive manner to the top of the bottom section of the cooling unit, namely by means of an adhesive connection, rivet connections, etc. Preferably, the lighting units are arranged on the top of the bottom section of the cooling unit such that the at least one opening in the holding element, the view of this releases. The opening is preferably of rectangular design and comprises all the lighting units attached to the base section. In an alternative embodiment, a plurality of rectangular openings are provided in the holding element, each of which is separated from one another by a web, so that each of the lighting units attached to the base section is each surrounded by an opening in the holding element. Advantageously, four openings for accommodating four lighting units are made in the holding element, the openings being separated from each other by a web, ie, for example, three webs separating the openings are provided in order to obtain four openings. In yet another embodiment, at least two lighting units can be combined to form a lighting unit group, each lighting unit group being encompassed by an opening in the holding element. Alternatively, the lighting units can be arranged individually and in lighting unit groups, each of which is surrounded by an opening. The number and arrangement of the openings and webs is in no way limited to the described embodiments, rather the arrangement of the openings and webs depends on the arrangement of the lighting units. The openings made in the holding element are by no means rectangular openings limited, rather the shape and / or size of the openings is dependent on the design of the lighting units or lighting unit groups.

The at least one holding element also serves for fastening the lamp insert module in the lamp housing or in the existing housing. For this purpose, the at least one holding element has a base section comprising the rectangular opening and edge sections adjoining at least two opposite sides of the base section. Depending on the type and design of the luminaire housing, the edge sections can also connect to three or four sides of the base section. Fastening sections are provided on the edge section, in this case in the form of an opening for the passage of a connecting means such as e.g. a screw. The opening for the passage of a connecting means preferably has at least one circular or an elongated hole-like section extending in the longitudinal direction of the respective edge section. The opening can preferably also have a circular section which merges into an elongated cross-sectional shape on one or both sides, the elongated cross-sectional shape preferably having a smaller diameter than that of the circular section. The illuminant insert module can thus be fastened in a simple manner in the luminaire housing of the tunnel luminaire. A major advantage of the invention is also to be seen in the fact that the cooling unit with light units and lens systems mounted thereon is only held by the at least one holding frame on the light housing of the tunnel light, so that depending on the size and / or design of the light housing of the tunnel light, the shape and / or size of the holding frame can be selected, ie cooling units of the same size can be used in different luminaire housings, since only the size of the holding frame has to be adapted to the size of the luminaire housing.

Furthermore, two or more cooling units can also be attached to a single holding element. The design of the illuminant insert for tunnel lights with a holding element and at least two cooling units attached to the holding element has the advantage that the modularity of the illuminant insert is again significantly increased. Accordingly, individual cooling units with the lighting units and lens systems attached to them can be replaced in a simple manner, in particular in a particularly cost-effective manner.

In a further advantageous embodiment, each cooling element is attached to a separate holding element. If each heat sink is arranged on a separate holding element, this is also referred to as a smaller-sized lamp insert module, i.e. For example, two individual light insert modules can form the insert for a light housing.

Furthermore, a bright, preferably white, coating is advantageously applied at least on the upper side of the holding element facing the tunnel carriageway. The light coating serves in particular to ensure that the light reflecting back from the transparent material, in particular glass or plexiglass pane, of the light housing into the light housing is ensured. The light beams emitted by the at least one lighting unit do not completely pass through the glass or plexiglass pane arranged in the cover of the lamp housing, so that some of the light beams are reflected back in the direction of the lamp insert module. Due to the light reflection caused by the light coating, the light reflected back from the glass or plexiglass pane is improved and illumination of the tunnel carriageway is achieved. Furthermore, the bright coating on the holding element has the great advantage that the light rays reflected back from the glass or plexiglass pane are only absorbed to a small extent, i.e. heating of the lamp insert module by means of back-reflecting light rays is thus significantly reduced.

In a preferred embodiment, the cooling unit consists of a bottom section, a side section and an abutment section and preferably has a U-shaped, C-shaped or Z-shaped cross-sectional profile. Due to this design of the cooling units, they are extremely simple and inexpensive to manufacture. The side section advantageously extends both perpendicular to the bottom section and perpendicular to the contact section. However, it is also conceivable that the side section and the bottom section enclose a first angle and the side section and the contact section enclose a second angle, the first angle or second angle being less than or greater than 90 degrees. The cooling surface of the cooling unit can be increased further by the profile and / or contact section being profiled, for example the profile and / or contact section can have a wavy or zigzag-like cross-sectional profile. Furthermore, the size of the bottom section, side section and contact section can be designed differently. The size of the base section is preferably selected such that preferably two to twelve, in particular two or four, lighting units can be attached. The contact section preferably has the same size as the bottom section, but the contact section can also be made smaller or larger than the bottom section. The size or length of the side section is essentially dependent on the height of the installation space in the lamp housing.

In order to increase the cooling capacity, in an advantageous development the cooling unit has a bottom section, two first bending edges extending along a longitudinal axis or two second bending edges extending transversely to the longitudinal axis, a side section each adjoining the bending edges of the bottom section and a contact section adjoining the side section in each case . Furthermore, in a further advantageous embodiment, the cooling unit has a bottom section, two first bending edges extending along a longitudinal axis, two second bending edges extending transversely to the longitudinal axis, a side section adjoining the bending edges of the bottom section and a contact section adjoining the side section. In particular, by designing the cooling unit with four side sections and at least one contact section each adjoining the side section, the cooling surface is significantly enlarged.

The contact sections advantageously each have a free end, the free ends of the opposite contact sections pointing toward or away from one another or in the same direction. The respective contact section serves on the one hand as a contact surface for support on the inner wall of the lamp housing, on the other hand the cooling surface is increased by the respective contact section and accordingly the cooling capacity is increased. In a particularly preferred embodiment, the contact sections are bent in such a way that the free ends of the respectively opposite contact sections point away from one another. In an alternative embodiment, the free ends of the first and third contact sections point in the same direction, that is to say the free contact ends of the first contact section point away from the cooling unit, while the third contact section opposite the first contact section points into the interior of the cooling unit or in the direction of the cooling unit extends first investment section, or vis-à-vis. At the same time, the free ends of the second and fourth contact sections point away from one another. The reverse case is also possible, in which the free ends of the first and third contact sections are separated from one another point away and the free ends of the second and fourth contact section point in the same direction. In a further preferred embodiment, the free ends of the respectively opposite contact sections, either the first and third contact sections or the second and fourth contact sections, point towards one another. To increase the cooling surface, it is advantageous that the cooling unit has a side section on each bending edge of the bottom section and an abutment section adjoining the side section.

According to a preferred embodiment, the cooling unit is formed in one piece. In particular, the manufacture of the cooling unit is simple and inexpensive due to the one-piece design. Accordingly, the metal jacket or the development of the cooling unit to be bent is punched out from a flat material section made of metal or a sheet metal. The cooling unit is then created by bending the metal jacket around the specified predetermined bending lines. The bending of the side sections along the first or second bending edges and the bending of the contact sections along the third or fourth bending edges can take place either in a separate working step or in a common working step.

It is advantageous that the side sections and / or the contact sections have a plurality of recesses or openings to enlarge the cooling surface. As a result, several recesses or openings can be made both in the side sections and in the contact sections. The recesses or openings are preferably made by punching or laser beam cutting before the metallic flat material is bent. The cooling surface can be significantly increased by introducing recesses or openings of different shape and / or depth and / or size. It has proven to be particularly effective to design the recesses or openings in a cube shape. With this configuration of the recesses or breakthroughs, the greatest cooling surface gain could be achieved and the cooling capacity could thus be further increased.

In a further advantageous embodiment, the recesses or openings are arranged in one or more rows in the side sections and / or contact sections. The recesses or openings preferably form a plurality of rows of holes oriented parallel to one another, the individual holes in a row preferably being square.

Furthermore, in an advantageous embodiment, the cooling unit is made of aluminum or an aluminum alloy, preferably the aluminum alloy AlMg ₃ .

The surfaces of the cooling unit are preferably black anodized to further increase the cooling capacity.

It is also advantageous that each of the lighting units has a lens system which interacts with the lighting unit, the lighting unit and lens system being connected to the base section. A double-symmetrical optic, which is designed to have a relatively wide beam, preferably functions as the lens system. it can illuminate a large part of the width of the carriageway in the tunnel. In order to be able to illuminate the roadway width as well as possible, it is advantageous to mount the tunnel light centrally in the tunnel or up to 1 m off-center. The lens system has a lens carrier and a plurality of lens bodies arranged on the lens carrier, which are arranged in such a way that the respective lens body can interact with the corresponding associated illuminant in the assembled state.

Particularly preferably, at least one lamp insert module, at least one supply unit that can be plugged onto the lamp insert module, and possibly one device carrier, represents a conversion kit or a conversion kit. Such a conversion kit or conversion kit simplifies, in particular, the exchange of existing device carriers and reflector lamp modules. The equipment rack is preferably mechanically identical to existing equipment rack with e.g. HIT / HST luminaires and can be installed in the luminaire housing without tools using fastening means, in particular wing screws and connectors. At least one supply unit, which is at least equipped with an LED driver, as well as means for supplying a supply voltage and means for transmitting control signals are preferably arranged on the device carrier.

Further developments, advantages and possible uses of the invention also result from the following description of exemplary embodiments and from the figures. All of the features described and / or depicted, in themselves or in any combination, are fundamentally the subject of the invention, regardless of how they are summarized in the claims or their relationship.

Ways of Carrying Out the Invention

In Fig. 1 the reference numeral 1 shows an illuminant insert module 1 for use in a luminaire housing of a tunnel luminaire. Such a tunnel luminaire is used to illuminate a tunnel and is accordingly attached to the tunnel ceiling or to the side wall of the tunnel. A plurality of tunnel lights arranged in parallel and / or in series can also be provided in a tunnel, which are switched and / or controlled together or in groups via a central control unit, not shown in the figures.

The lamp insert module 1 consists of at least one cooling unit 2, which is produced by bending from a metallic flat material and forms a heat sink, the cooling unit 2 being formed in one piece and having a rectangular, flat bottom section 3. The cooling unit 2 is preferably made of aluminum or an aluminum alloy, in particular the aluminum alloy AlMg ₃ . To increase the cooling capacity, the surfaces of the cooling unit 2 are black anodized to increase the cooling capacity.

The bottom section 3 has an upper side 6 facing the tunnel carriageway and an underside 7 opposite this, facing the lamp housing or the lateral tunnel wall or tunnel ceiling. The bottom section 3 extends along a longitudinal axis LA and runs parallel to a plane E. Furthermore, the bottom section 3 has an edge on the edge, a so-called bending edge, the bending edges extending in the longitudinal direction LA being the first bending edges 8, 8 'and the bending edges connecting the first bending edges 8, 8 'are referred to as second bending edges 9, 9'. Both the first two bending edges 8, 8 'and the two second bending edges 9, 9' face each other and each run parallel to one another.

To increase the cooling surface, at least two bending edges 8, 8 ', 9, 9' of the bottom section 3, which are rectangular and which protrude from the underside 7, are formed. In particular, the cooling unit has two opposite, rectangular side sections 4.1, 4.3 extending from the first bending edges 8, 8 'and two opposite, rectangular side sections 4.2, 4.4 extending from the second bending edges 9, 9'. on, with each opposite side sections 4.1, 4.3 and 4.2, 4.4 are each arranged parallel to one another and have the same width and length. In the direction of the luminaire housing or lateral tunnel wall or tunnel ceiling, the side sections 4.1-4.4 are delimited by further bending edges 27, 27 ', 28, 28'. The respective side sections 4.1-4.4 are produced by bending the metallic flat material along the respective predetermined bending line 14.

In addition, the cooling unit 2 has at least one contact section 5.1-5.4 which adjoins the side section 4.1-4.4, is spaced apart and runs parallel to the bottom section 3. The cooling unit 2 according to Figure 1 has, for example, four side sections 4.1-4.4, a rectangular, spaced and parallel to the bottom section 3 abutting section 5.1, 5.3 adjoining the side sections 4.1, 4.3 running parallel to the longitudinal axis LA and each of the side sections 4.2, 4.4 running transverse to the longitudinal axis LA a rectangular, spaced and parallel to the bottom section 3 running section 5.2, 5.4 connects. Each of the sections 5.1-5.4 is delimited by a free end 15.1-15.4. Depending on the design of the luminaire housing, the free ends 15.1-15.4 of the respectively opposite system sections 5.1-5.4 can point towards or away from each other or in the same direction. In the present exemplary embodiment, the free ends 15.1, 15.3 of the contact sections 5.1, 5.3 point in the same direction, while the free ends 15.2, 15.4 of the contact sections 5.2, 5.4 point away from one another. The opposite plant sections 5.1, 5.3 and 5.2, 5.4 have the same width and length. However, the dimensions of the system sections 5.1-5.4 do not have to have the same width and length. Rather, the dimensions of the system sections 5.1-5.4 can vary depending on the size and design of the luminaire housing.

To increase the cooling capacity, in the Figures 1 to 5 not shown, the side sections 4.1-4.4 and / or the contact sections 5.1-5.4 have several recesses or openings to enlarge the cooling surface. Furthermore, the recesses or openings can be arranged in one or more rows in the side sections 4.1-4.4 and / or contact sections 5.1-5.4.

The lamp insert module also consists of at least one light unit 12 comprising a plurality of light-emitting diodes 20, which is arranged on the upper side 6 of the base section 3 of the cooling unit 2 and is thermally conductive with the Bottom section 3 of the cooling unit 2 is connected. The at least one lighting unit 12 has a preferably rectangular printed circuit board 18, in particular an aluminum core printed circuit board, on which a plurality of light-emitting diodes 20 are arranged, preferably in groups. In addition to the light-emitting diodes 20, at least one corresponding connection device 19 is provided on the printed circuit board 18 for supplying a supply voltage and, if necessary, for electronic components required to control the light-emitting diodes. How from Fig. 1 it can be seen that four spaced-apart lighting units 12 are provided, each with four light-emitting diode groups, one light-emitting diode group each comprising four light-emitting diodes 20. A lighting unit 12 thus has sixteen light-emitting diodes 20. It goes without saying that the number of light-emitting diodes 20 per group and / or module and the number of modules per se can be chosen arbitrarily in order to achieve a desired light output or lumen output. So-called "high-power" light-emitting diodes with high light output are preferably used. The light emitting diodes 20 can also be designed to be dimmable.

The illuminant insert module 1 also has at least one plate-shaped holding element 10 for fastening the illuminant insert module 1 to the lamp housing of the tunnel lamp, at least one preferably rectangular opening 11 being introduced into the central region of the holding element and the region comprising the opening 11 forming the base section 23 of the Holding element 10 forms. Due to the opening 11 made in the central area of the holding element 10, the base section 23 is designed like a frame. Alternatively, a plurality of rectangular openings 11 can be provided in the holding element 10, each of which is separated from one another by a web, so that each of the lighting units 12 attached to the upper side 6 of the base section 3 is each surrounded by an opening 11 in the holding element 10. The base section 23 of the holding element 10 is adjoined on at least two opposite sides by a narrow edge section 21, which is in each case provided with at least one fastening section 22. While the holding element 10 is arranged on the upper side 6 of the bottom section 3 of the cooling unit 2, the fastening sections 22 provided on the edge section 21 serve to fasten the holding element 10 to the lamp housing. The attachment is preferably carried out by means of a screw connection. For this purpose, the fastening sections 22 are designed as circular openings and / or slot-like openings. In the present exemplary embodiment, an edge section 21 adjoins all four sides of the base section 23, each of the edge sections 21 at least one, preferably two or three, Fastening sections 22 has. Due to the edge-side fastening sections 22, the holding element 10 can be easily mounted on the lamp housing of the tunnel lamp. Furthermore, a bright, preferably white, coating is applied at least on the upper side 6 of the holding element 10 facing the tunnel carriageway. The light coating serves on the one hand to ensure that the light reflecting back from the transparent material, in particular glass or plexiglass pane, of the lamp housing into the lamp housing and consequently to improve the illumination of the tunnel roadway, and on the other hand to improve the absorption of the light reflected back from the glass or plexiglass pane to reduce.

When assembled according to Fig. 2 the four lighting units 12 are attached to the top 6 of the cooling unit. In order to facilitate the attachment of the lighting units 12 to the cooling unit 2, corresponding drill holes 26 have already been made in the base section 3. In the present case, four drill holes 26 arranged in a row and spaced apart from one another are provided for fastening the four lighting units 12 in the base section 3, the four rows each being arranged parallel to one another. The lighting units 12 are preferably attached by means of detachable connecting means such as screws. In the assembled state, the four lighting units 12 are received by the one opening 11 in the holding element 10 and enclosed in a frame-like manner by the holding element 10. The rectangular opening 11 in the holding element 10 gives the holding element 10 a view of the lighting units 12, ie the light radiation generated by the light-emitting diodes 20 can pass through the opening 11 in the holding element 10 and thus produce the desired lighting effect.

The supply voltage and / or control signals are supplied to the lighting units 12 via a central connection unit 25, which is preferably provided in the region of the base section 23 of the holding element 10. The central connection unit 25 is preferably designed as one or more plug-in connection units. Like from the Figures 3 and 4th can be seen, the central connection unit 25 is preferably arranged on the side of the holding element facing the cooling unit 2.

As in Figure 5 shown, the lamp insert module 1 for starting up the lamp insert module 1 via the central connection unit 25 by means of a connecting cable and a plug unit 24 on a first plug part 29 of a Device carrier 32 connected. The plug connection between the plug unit 24 and the first plug part 29 is preferably a 3-pin connection. The device carrier 32 has at least one supply unit 30, which is at least equipped with an LED driver unit, as well as means for supplying a supply voltage and means for transmitting control signals. The device carrier 32 is in turn connected to a second plug part 31, which is preferably designed as a 5-pin connection, on a central power supply and / or central control unit - not shown here. The device carrier 32 is preferably part of the lamp insert module 1, as a result of which a complete kit or conversion kit is made available.

Finally, each of the lighting units 12 has a lens system 13 which interacts with the lighting unit 12, both the lighting unit 12 and the lens system 13 being connected to the base section 3 of the cooling unit 2. Each lens system 13 has a lens carrier 16 and a plurality of lens bodies 17 arranged on the lens carrier 16, which are arranged in such a way that the respective lens body 17 can interact with the corresponding associated light-emitting diode 20 in the assembled state. Accordingly, like the lighting unit 12, the lens carrier 16 is preferably rectangular and essentially has the length and width of the lighting unit 12. The multiple lens bodies 17 arranged on the lens carrier 16 are likewise divided into lens body groups. Like from the Figures 1 and 2nd such as Figure 5 it can be seen that four lens carriers 16, each with four lens body groups, are provided, one lens body group each comprising four lens bodies 17. Thus, a lens system 13 has sixteen lens bodies 17.

The lens system 13 preferably has a double symmetrical optic which is designed to be extremely wide in terms of the width of the roadway of the tunnel. The double symmetrical optics create a light distribution curve that is ideal for use in tunnel luminaires.

The lamp insert module 1 can be adapted to the type of tunnel light and / or position of the tunnel light, ie mounting the tunnel light on the tunnel ceiling or on the side tunnel wall, by a special configuration of the lens system 13.

The lens system 13 is also fastened together with the lighting unit 12 to the bottom section 3 of the cooling unit, preferably screwed.

In Figure 6 The reference number 1 discloses an alternative embodiment variant of a lamp insert module for use in a lamp housing of a tunnel lamp. The main difference to the embodiment in Figure 1-5 is that the illuminant insert module 1 consists of two cooling units 2, each cooling unit 2 consisting of a rectangular, flat bottom section 3a, 3b with an upper side 6a, 6b and a lower side 7a, 7b. Furthermore, each cooling unit 2 has at least one side section 4a, 4b adjoining a bending edge 8a, 8b of the bottom section 3a, 3b and projecting from the underside 7a, 7b, this preferably being rectangular and flat. Furthermore, the cooling unit 2 has at least one rectangular, flat contact section 5a, 5b which adjoins the side section 4a, 4b. How from Figure 6 can be seen, the bottom section 3a, 3b, the side section 4a, 4b and the contact section 5a, 5b of each cooling unit 2 have a U-shaped cross-sectional profile, the free ends of the U-shaped cross-sectional profile of the cooling units 2 pointing towards one another. Optionally, the free ends of the U-shaped cross-sectional profile of the cooling units 2 can also point away from one another, so that the two side sections 4a, 4b abut one another. By providing at least two cooling units 2, the lamp insert module can be repaired extremely individually. If a lighting unit 12 fails, only the cooling unit 2 on which the defective lighting unit 12 is installed has to be replaced or removed.

Another special feature is that the two cooling units 2 can be fastened to the luminaire housing of the tunnel luminaire by means of a common holding element 10, while at least one lighting unit 12 and an associated lens system 13 are attached to each cooling unit 2. The lighting units 12 of each cooling unit 2 are connected to a separate central connection unit 25a, 25b, via which the supply voltage and / or control signals are supplied to the lighting units 12. The central connection units 25a, 25b are preferably arranged in the region of the base section 23 of the holding element 10 and connected to a supply unit 30 by means of plug units 24a 24b. The supply unit 30 does not necessarily have to represent a common supply unit; rather, each plug unit 24a, 24b can also be connected to its own supply unit 30. In order to further increase the modularity of the lamp insert module 1 also the holding element 10, in the Figures 1 to 9 not shown, consist of at least two plate-like holding elements, ie each cooling unit is attached to a separate holding element. In this special case, one also speaks of two separate lamp insert modules, which are inserted together in a lamp housing and form the lamp insert module. With this special embodiment, the maintenance or repair of the lamp insert module can again be significantly simplified.
