Description

The invention relates to a lamp, in particular as a work, film or sports event lamp, comprising at least one holding element to which at least one LED module is pivotably attached, which can be charged with voltage via supply lines, the at least one LED module having an approximately triangular shape Has a flat basic shape and a side surface is equipped with LEDs, preferably power LEDs, and the rear side of the LED module is provided for heat radiation and there are connecting elements for the holding element at least on one side edge.

Lights are offered in a variety of forms, for example as indoor lights in the form of ceiling or wall-mounted lights. In this case, the lights can accommodate one or more light sources to which voltages are applied. The lights are made of either glass, ceramics or plastic, with a lampshade also being provided, which may have a frame with a fabric cover. In addition, built-in lights are known, which are embedded either in a wall or on a ceiling. All of these lights are primarily for indoor use. There are also various housing shapes for lights that are used outdoors, for example as garden lighting or house lighting in the form of built-in lights, with the built-in lights being able to be installed in a roof superstructure or in an entrance area. In addition, various waterproof garden lights are embedded in the ground or in existing patio areas. Outside, there is a need to comply with the regulations regarding moisture protection. Many of the lights are intended for stationary installation and are not transportable.

There is also a market for high-performance lights, which are used, for example, to illuminate work surfaces or as film equipment or at sporting events. In such cases, a high light intensity is important because in As a rule, such lights are arranged at a height of more than 3 meters, occasionally also over 10 meters. In addition, there is the possibility that such lights are attached to a tripod and can thus be positioned at the required height for the different purposes.

Due to changes in the regulations and the partial omission of light sources, such as halogen light sources, there is a need to develop a new lighting concept, which is mainly geared towards LEDs. On the one hand, the light intensity should be increased and, on the other hand, the power consumption should be reduced as much as possible.

The US filing WO 2010/119378 A1 and WO 2011/015971 A1 disclose a lighting system made up of suspended struts, which can be adjusted in height relative to a holding device and have individual LED lights. With the help of the lighting system, for example, the entire ceiling of a room can be equipped.

From the US Application 2014/0168983 A1 a visual display is known, wherein individual displays are connected in an almost square shape with a connecting element in the corner area and are pivotable. Four displays are connected to each other on a connecting element and can be swiveled in different directions relative to each other.

All of the embodiments are primarily intended for indoor use and can only be used to a limited extent for outdoor use. Furthermore, the illumination of large areas with the known lights is not possible.

The present invention is therefore based on the task of demonstrating a new type of lamp as a work, film or sports event lamp, which is characterized by a robust and simple structure and a high degree of flexibility when used indoors and outdoors.

To solve the task, it is provided that the holding element consists of a polygonal frame, which extends over 180 degrees or 360 degrees and accommodates several adjacent LED modules or consists of two straight mounting brackets, which are attached to the wall or ceiling and several adjacent Record LED modules in such a way that a light band is created, the at least one LED module being equipped as a connecting element with eyelets which receive the holding element, so that the at least one LED module can be pivoted at least partially around the holding element. Further advantageous configurations of the invention result from the dependent claims.

By using an almost triangular flat LED module, an extremely compact light is created that is easy to transport and offers the option of being used as a wall, ceiling or outdoor light. The entire structure is kept flat due to the basic shape of the LED modules used and does not lead to any restrictions during assembly. As a rule, these advantages do not arise in the case of stationary installation, while in contrast the at least one LED module can also be used for lights that can be set up variably. The LED modules have connecting elements for a holding element on one side edge, so that on the one hand stationary installation is possible, but also pivoting of individual LED modules is made possible due to the eyelets. In such a case, the holding element is constructed in such a way that it can accommodate or support the connecting elements of the LED modules, and due to an extremely stable design, sufficient support can be guaranteed via the connecting elements if the holding elements are optionally attached to a wall or ceiling are mounted or possibly used for use with a tripod.

Another advantage results from the fact that the lamp is equipped exclusively with LEDs, so that a low voltage can be used outdoors. Movable articulation of an LED module to the holding elements also enables the alignment of the LED modules in a desired direction and a quick possibility of realignment if this is necessary. By choice A suitable holding element and suitable connecting elements also ensure that the LED modules can be pivoted, which means that the lighting alignment can be changed from a fixed location.

In a further embodiment of the invention, it is provided that several LED modules are assembled and connected via the holding element to form a semicircle or full circle. A connection is made here, for example, via the connecting elements and a holding element, it being possible to apply voltage to all the LED modules via a line cable. By arranging the LED modules in a semi-circle or full circle, it is possible to achieve high light intensity in a very small space, such as is required as a work light, for example. Alternatively, there is the possibility that several LED modules are joined and connected via the holding element in the form of strips. Such an arrangement of the LED modules makes it possible to produce a light strip which is mounted on a wall or preferably on a ceiling, with a number of light strips being spaced apart from one another on the ceiling if the size is appropriate. The light intensity of the LED modules is so high that not only small but also large halls can be completely illuminated. To open the LED modules, it is provided that the at least one LED module has a cable connection a supply range can be applied, or that several LED modules are connected to one another and a supply range can be applied at least via a cable connection.

In a further embodiment of the invention it is provided that the holding element consists of a polygonal frame which extends over 180° or 360°. A polygonal frame is used because the LED modules are triangular in shape and are attached to the holding elements with a side edge. In such a case, three LED modules with at least three straight sections of the holding element are required to cover an arc of 180°. If a 360° arc is to be achieved, a correspondingly double number of LED modules is required. In a further embodiment of the invention, there is also the possibility that two polygonal frames of 180° each are connected to one another via a joint, so that a full circle of 360° is achieved by opening these two frames. This measure makes the transport much easier to handle and therefore easier.

In a further embodiment of the invention, it is provided that the Helte element consists of two fastening supports which are fastened to the wall or ceiling and accommodate a number of LED modules lying next to one another in such a way that a light band is formed. For this purpose, the individual LED modules are arranged alternately with a triangular apex, formed by the two isosceles side edges, in opposite directions. The length of such a light band is irrelevant and can be extended later if necessary. The light strips are primarily used in production halls where high light intensity is required, for example in aircraft assembly.

In the case of polygonal frames that extend over 180° or 360°, the at least one, preferably several, LED modules can be pivoted at least partially around the frame, thereby influencing the area to be illuminated. With a full circle of 360°, the lamp at the corresponding height illuminates an almost circular area on the floor. So far If some of the opposite LED modules are pivoted, the illumination can change from a circular shape to an elliptical shape. Such illumination areas are preferably required for road or rail construction. A fully equipped lamp in a 360° version achieves 155,000 lumens.

In a further embodiment of the invention, it is provided that the triangle tips can be raised or lowered in the direction perpendicular to the LED module. By swiveling the modules out of the LED module level, it is possible to vary the area to be illuminated, with the individual LED modules being either raised or lowered from the module level with their tips, depending on the selected installation of the light. When all LED modules are pivoted completely, the radius of the light cone can be increased. By raising or lowering the individual LED modules, they can be set up in a pyramid or cone shape. In order to achieve sufficient stability in the respective position of the LED modules, it is also provided that the raised triangular tips can be locked in several locking stages or adjusted continuously. This prevents, for example, individual LED modules from being moved out of their original deflection when wind loads occur.

The triangular tips of an LED module can be locked, for example, by a metal strip which is arranged between two permanent magnets, the metal strip being connected to the sleeve via a joint and the metal strip having a curvature at the free end which occurs when the LED modules are lifted leads to a compensatory movement and the metal strip remains between the permanent magnets.

For reasons of stability and construction simplification, it is provided that the at least one LED module is equipped with eyelets, which receive a holding element in the form of a tube, a round strut or a round fastening support. The LED modules can thus be pivoted about the bracket, the strut or the mounting bracket, with excellent stability being achieved through the appropriate size of the respective eyelets and retaining elements. The holding element can, for example consist of a round fiber, glass fiber or carbon fiber rod. In order to obtain a structure that extends 180° or over 360°, the fiber, glass fiber or carbon fiber rods are connected to one another with corner connectors. The corner connectors themselves are connected to a central part via tension wires, similar to a wheel hub, so that after all components have been assembled, the retaining elements are prestressed towards the center in order to create the necessary strength. The central part takes on the function of a hub, as found on a wheel.

To mount the LED modules, first push the rods through the existing eyelets of the LED modules and insert them into the existing holes in the corner connectors and fix them with screws. For this purpose, the supporting rods have a diameter which corresponds to the inner diameter of the eyelet. In addition, sleeves are pushed on between the eyelets and on the side of the LED modules to the corner connectors, so that the LED modules are prevented from slipping sideways. The eyelets of the LED modules are also arranged laterally offset from the center so that, for example, two LED modules can be attached to a tube if a shape that deviates from the hexagon is desired. The fiber, glass fiber or carbon fiber rods as a tube fulfill the function of a guide rod, while the pushed-on sleeves carry out a lateral fixation between the corner connectors.

Because the LED modules are equipped with a large number of individual LEDs, preferably power LEDs, it is imperative that the heat generated is dissipated. For this reason, the back of the LED modules is equipped with cooling fins, while the front of the LED modules has a plastic cover. The plastic cover is diffuse for light scattering to reduce the glare of individual LEDs. In addition, the plastic cover can be provided with punctiform or line-shaped elevations or, if necessary, with corrugations, as a result of which an increase in surface area is achieved and thus an improvement in the light scattering is achieved.

In a further embodiment of the invention, it is provided that the at least one LED module is equipped with LEDs of different colors, in particular RGB colors. This makes it possible to let each individual LED module or group of LED modules light up in different colors. There is also the option of making a continuous color change and adapting the coloring to the intended use. Provision is also made for the at least one LED module to be dimmable in order to carry out brightness control, with a GMX controller preferably being used, by which the individual LED modules are controlled.

In order to mount the lamp in a 180° or preferably 360° arrangement of the individual LED modules at a selected working height, it is also provided that the central part in the form of a hub sleeve is used as a fastening device, with stationary mounting or variable height-adjustable mounting possible with a tripod.

The light can be switched on and off and dimmed via a Bluetooth connection. In addition, it is also possible to set a specific color spectrum.

The present invention is characterized by a high degree of flexibility in adjustment and an extremely stable construction, which means that it is suitable for the intended use in the area of work lights, film or sporting events. Individual lights can be designed as polygonal lights that extend over 180° or 360°. Alternatively, the LED modules can be used to create a light strip that can be used to illuminate large halls, with any length possible. The stability of the lamp is achieved by the fact that there is a hub in the center and individual holding elements are connected in a polygonal manner using corner connectors, whereby the corner connectors can also be braced with the middle part using tension wires and thus the shape of the lamp after assembly results in a high degree of stability leads. Of course, if necessary, the individual wires can be retensioned in order to to counteract material wear or to replace individual LED lights. Due to the dimmability and setting of the color temperature, the light can be adjusted to the required requirements, which ensures a high degree of possible uses.

The invention is explained in more detail below with reference to the figures.

figure 1 shows an LED module 1 in a perspective top view, which consists of a light-transparent plastic cover 2 and a cooling body 3 on the rear. The shape of the LED module 1 is an isosceles triangle, so that several LED modules 1 can be arranged next to one another to form a semicircle or full circle, or to form a light band, with the LED modules 1 alternating with their respective tips in the light band to be ordered. The shape of the LED module is an isosceles triangle, so that the side edges of the same length can be joined together without any problems. The upper plastic cover 2 is screwed to the heat sink 3 via screw bolts 4 , which at the same time forms the back of the LED module 1 . In this case, the plastic cover 2 preferably consists of a translucent material, so that the light emitted by the power LEDs can escape through the plastic cover 2 in a scattered manner. To enlarge the surface, the plastic cover 2 is provided with straight, rounded elevations 5 at equidistant intervals. The elevations 5 transition into a curved shape in the edge region, following the shape of the plastic cover 2 . The heat sink 3 consists of individual cooling ribs 6 which are arranged on the rear over the entire width of the LED module 1 . The cooling fins 6 are straight in the middle area and are provided with a rounding 7 in the edge area. There is the possibility of fixing a single LED module via a holding element (not shown) via two eyelets 8 formed in one piece with a bore 9 . The eyelets 8 with bores 9 make it possible to arrange the LED modules 1 in a plane in which the holding element is also arranged, with the individual LED modules 1 being able to be pivoted out of the plane. When constructing a lamp with six individual LED modules 1 extending over 360°, there is thus the possibility of raising the tips of the LED modules 1 aligned with the center, as a result of which the shape of a pyramid arises.

Due to the pivotability of the LED modules 1, a variable light cone can be set, taking into account the height at which the LED modules 1 are arranged. In the normal case, when all the LED modules 1 are in the same plane, there is a circular bulge, the diameter of which can optionally be increased by pivoting all the LED modules 1 . By pivoting two LED modules 1 lying opposite one another, the illuminated area can be converted from the round shape into an almost elliptical shape. Such illumination is required, for example, for repair work in road and rail construction.

figure 2 shows the LED module 1 with the upper plastic cover 2 and the heat sink 3 in a perspective view from below. This view makes it clear that the heat sink 3 has a straight-line edge profile 10 of the cooling fins 6 in the central area of the LED light 1, while in the edge area this course of the edges changes into a curvature 11 . In order to avoid damage to the individual cooling fins 6 , a plurality of integrally formed supports 12 are provided which protrude slightly from the cooling fins 6 . This prevents individual cooling fins 6 from being bent, which is easily possible in rough conditions on a construction site. A voltage cable can be connected via screw connections 13, which are standard PG screw connections. It is possible here for a single LED module 1 to be connected to a cable, but the second screw connection 13 can also be used to connect to other LED modules if these are assembled in a 360° arrangement to form a lamp, for example. The eyelets 8 with a bore 9 and a suitable holding element allow swiveling with respect to the holding element in order to align the individual LED modules 1 with a specific geometric shape. The size of the cooling ribs 15 ensures that there is a large surface area to dissipate the heat generated by the power LEDs arranged underneath the plastic cover 2 .

figure 3 shows a plan view of an LED module 1 with a view of the plastic cover 2. The bolts 4, which are distributed over the entire edge area of the LED lamp 1, are used to screw the rear side, and namely the heat sink 3. The two eyelets 8 make it possible to pivot the individual LED modules 1 within a suitable holding element.

figure 4 shows a side view of the LED module 1 with the upper plastic cover 2 and the lower heat sink 3 with a view of the screw connections 13 and eyelets 8. This view clearly shows the height of the individual cooling ribs 15, which are significantly greater than the plastic cover . The overall surface of the cooling fins 15 is designed in such a way that the heat generated by the power LEDs, which are arranged underneath the plastic cover 2, can be completely dissipated to the rear.

figure 5 shows a top view of a lamp 20 with a total of six LED modules 1. The individual LED modules 1 are in FIGS Figures 1 to 4 presented and described in detail. figure 5 now shows an assembly of six LED modules 1, which are connected to one another by means of the eyelets 8 via a retaining element 21. The holding element 21 consists of corner connectors 22, which are designed in two parts, namely an outer corner connector 23 and an inner corner connector 24. The outer and inner corner connectors 23, 24 are connected to one another via screw connections (not shown) and are provided for receiving a pipe 25. a corner connector 22 receiving two tubes 25 in each case. Just as six LED modules 1 are used in the lamp 20 , there are also six corner connectors 22 which are each connected to one another via a tube 25 . Three sleeves 26 , 27 , 28 are pushed onto the tube 25 , the sleeve 27 being placed between the two eyelets 8 of an LED module 1 , while the sleeves 26 and 28 are arranged to the side of the sleeves 8 . The sleeves 28, 27, 28 prevent the LED modules 1 from slipping sideways on the tube 25 between the corner connectors 22. The eyelets 8 are offset from the center in relation to the LED module 1 so that two LED modules 1 can be pushed onto a tube 25 and fastened. This makes it possible to enlarge the lamp 20 shown by at least one additional LED module 1, optionally by up to six additional LED modules 1.

In order to absorb radial forces of the lamp 20, each corner connector 22 is connected to a sleeve 30 via a threaded sleeve 29, with two V-shaped tension wires 31 extending from the sleeve 30, which are connected to a hub sleeve 32 located in the center. The hub sleeve 32 is similar to a bicycle hub, while the tension wires 31, sleeve 30 and threaded sleeve 29 correspond to a spoke. By tightening the corner connectors 22, for example by means of a threaded bolt which can be screwed into the threaded sleeve 29, an extremely stable ring is produced which locks and securely holds all the LED modules 1 in the respective position. The hub shell 32 also serves to receive the end of a tripod or the like, so that the lamp 20 can be arranged at a desired height. In this case, there is easily the possibility that the lamp 20 is held by a ceiling or by a crane. In the foreground, however, is a tripod, which is adjustable in height and thus offers the possibility of placing the lamp 20 at the desired height.

The individual LED modules 1 can be pivoted out of the plane of the lamp 20 relative to the tube 25 and are held in the respective position by a lock. There is the possibility here that only individual LED modules 1 are pivoted, preferably the opposite LED modules 1, or that all LED modules 1 are uniformly pivoted out of the plane, thereby increasing the illuminated area. The locking of the individual LED modules 1 relative to the holding element 21 can take place, for example, by means of a fine toothing with clamping latching means on the tube 25 or the sleeve 8 .

The lamp 20 is assembled in such a way that first the inner corner elements 24 are connected to the threaded sleeve 29 via a clamping screw, which in turn are connected to the hub sleeve 32 via the sleeve 30 and the tension wires 31 .

The tube 25 is pushed through the eyelets 8 of the LED modules 1, the middle sleeve 27 and the side sleeves 26, 28 being able to be pushed on at the same time. A weight-saving material, for example a carbon tube section, is preferably used for the sleeve 26 , 27 , 28 . An LED module 1 connected to the tube 25 in this way is then placed against the inner corner connectors 24 and screwed using the outer corner connectors 23 in such a way that the tube 25 is held in a clamped manner. Due to the selected screw connection of the corner connectors 22, there is the possibility here of replacing an individual LED module 1 that may be defective at any time, if this is necessary.

The leads of the LED modules 1 are in the figure 2 shown and are located in the figure 5 below the LED modules 1 shown. The supply cable can here be wound up for transport via angles 32 projecting radially outwards, as a result of which the outer dimensions of the lamp 20 are not changed and the possibility is created of including the lamp 20 in a carrying bag.

figure 6 shows a top view of a light strip 40, which is provided for accommodating a plurality of LED modules 1 for attachment to a wall or ceiling. The individual LED modules 1 are pushed onto a holding element 41, 42 for this purpose. As in the case of the lamp 20, the retaining element 41, 42 can consist of an inner tube and an outer sleeve, the sleeves preventing the LED modules 1 from being displaced laterally. In this way, a uniform distance between the LED modules 1 can be maintained. The length of the holding elements 41, 42 is determined by the desired length of the light band 40, with the possibility that several individual holding elements 41, 42 can be lengthened as desired with the aid of a coupling or a sleeve. The structure of the LED modules 1 corresponds to the representation in FIG Figures 1 to 4 and the associated description.

In the case of the light strip 40, the LED modules 1 are preferably arranged in one plane, locking also taking place via fine teeth and locking means between the holding means 41, 42 and the sleeves 8 of the LED modules 1 can. Other fastening options, for example by supporting the tips pointing to the opposite holding element 41, 42, of the LED modules 1 are also conceivable. In individual cases, however, it may be desirable for the LED modules 1 to be angled slightly out of the module plane so that the illuminated area can be varied.

figure 7 shows a perspective view of a lamp 20 with LED modules 1 arranged in one plane. The lamp 20 is arranged on a tripod 43 which is accommodated in the hub sleeve 32 and has the necessary stability with a tripod 44 . Depending on the height of the lamp 20, an area 45 is illuminated which, with this deflection of the individual LED modules 1, corresponds almost to a circular shape.

figure 8 shows a perspective view of a light 20 with two LED modules 1 folded out downwards. The light also rests on a tripod 43 with a tripod 44. Due to the two opposite LED modules 1, which are folded out downwards, an almost elliptical Area 46 illuminated.

By folding out several LED modules 1, on the other hand, an approximately circular area with a larger diameter is illuminated. The diameter of the respective illuminated area also depends on the position of the lamp 20, the higher the position is selected by extending the stand 43, the more the illuminated area 45 or 46 increases.

figure 9 shows the rear side of an LED module 1 in a perspective partial view. Essentially, the heat sink 3 can be seen here, while the LEDs are arranged on the opposite side. The LED module 1 is held by tension wires 31 which, starting from a sleeve 32, are guided to a hexagonal holding element. As already described, the LED modules 1 are connected to the retaining element via eyelets.

In order to achieve pivotability of the LED modules 1 , the triangular tips of an LED module 1 are locked by a metal strip 50 which is connected at one end to the hub sleeve 32 via a swivel joint 51 . Starting from the swivel joint 51, the metal strip 50 initially runs in a straight line and transitions into a curve 52, which has a thickened portion 53 at the end. The curvature 52 of the metal strip 50 is necessary so that, during a pivoting movement, the metal strip 50 runs between a fixing device in the form of a magnetic holder 54 during the entire movement sequence. The magnet holder 54 is connected to the underside of the LED module 1 via screw bolts 55 and consists essentially of a tab 56 with a magnet receptacle 57, which is shown as being round in the exemplary embodiment shown. In the magnet holder 57 there are two permanent magnets 58, 59 arranged opposite one another, which are fixed at a distance from one another, so that the metal strip 50 can slide back and forth between the permanent magnets 58, 59. The permanent magnets 58, 59 ensure that the metal strip 50 is held securely in any position and thus also the LED module 1.

In the exemplary embodiment, this is one of several possibilities, but another type of locking for the individual LED modules 1 in the lamp can also be provided without further ado.
