Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a visual display 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.
  • 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.
  • 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.
  • an almost triangular flat LED module 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the at least one, preferably several, LED modules can be pivoted at least partially around the frame, thereby influencing the area to be illuminated.
  • the lamp at the corresponding height illuminates an almost circular area on the floor.
  • 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.
  • the triangle tips can be raised or lowered in the direction perpendicular to the LED module.
  • the individual LED modules 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.
  • the radius of the light cone can be increased.
  • 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.
  • 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.
  • the supporting rods have a diameter which corresponds to the inner diameter of the eyelet.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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°.
  • 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.
  • 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.

  • FIG 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 .
  • 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.
  • 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.
