Definitions

  • the present invention relates to an LED light source, which has at least one LED board, which is arranged in a housing space formed by housing parts. More particularly, the invention relates to an LED light source capable of replacing conventional elongated fluorescent lamps or gas discharge lamps.
  • LEDs have meanwhile replaced conventional light sources such as light bulbs or fluorescent lamps in almost all areas of lighting technology. Due to the small dimensions of a single LED, which is often referred to as a punctiform light source, compared to conventional light sources, newly developed luminaires are usually designed specifically for the use of LEDs as illuminants. This relates to the storage or arrangement of the LED boards in the lamp housing and the optical means associated with the LEDs, via which the light is influenced in the desired manner.
  • retrofit lamps which are intended to replace classic bulbs such as incandescent bulbs or fluorescent lamps.
  • These retrofit lamps are designed such that they can be used in the same way as a conventional light bulb or fluorescent lamp and thus in existing luminaires that were designed for the use of such classic bulbs can be used.
  • a retrofit LED light bulb thus has, for example, essentially the shape of a conventional light bulb and a base corresponding to the standard, which can be screwed into a corresponding socket of a lamp.
  • the present invention is particularly concerned with LED light sources intended to replace fluorescent lamps or gas discharge lamps. These are therefore elongate light sources which are usually realized by using a plurality of individual LEDs arranged one behind the other in the longitudinal direction and usually arranged on one or more circuit boards.
  • LED light sources intended to replace fluorescent lamps or gas discharge lamps.
  • These are therefore elongate light sources which are usually realized by using a plurality of individual LEDs arranged one behind the other in the longitudinal direction and usually arranged on one or more circuit boards.
  • different solutions are known from the prior art, which aim in particular to emulate a classic fluorescent lamp as well as possible.
  • a light source in which an LED board in a elongated plastic tube is inserted the outer dimensions of which correspond to those of a fluorescent lamp.
  • JP 2003068130 A describes a lamp based on an LED module, which can be replaced in a very simple manner.
  • the luminaire has the following components: the LED module 1 with LED chips 6 mounted on a chip mounting surface 1a and power supply connection parts 3 for current or voltage supply via power supply cable 10, the supply and removed via the rear part 9 of the lamp become.
  • the LED module 1 is held mechanically on the one hand only by a module holding member 2 (a combination of connecting part 4 and electrically conductive and thermally conductive elastic leaf springs 7) on the other hand powered.
  • a module holding member 2 a combination of connecting part 4 and electrically conductive and thermally conductive elastic leaf springs 7
  • the present invention is therefore based on the object to provide a novel LED-based light source, which avoids the disadvantages mentioned above. It should therefore be made available on the whole an elongated arrangement for light output on LED basis, which is easy to assemble or manufacture and uses the light emitted by the LEDs light efficiently for lighting purposes.
  • the invention provides that the contacting of the used for use LED board (s) by means of interconnects, pads and spring contacts. These are on the one hand on the LED board and on the other hand arranged on housing parts of the LED light source, in such a way that the LED board (s) between two housing parts are held clamped and electrically contacting.
  • the invention is characterized in that on the receiving space facing away from the rear or outer side of the first housing part, an operating device for powering the at least one LED board is arranged, wherein the operating device is electrically connected by means of spring contacts with the means for electrical contacting.
  • the advantage here is that no complicated connection of a supply cable or even a soldering is required for mounting the operating device.
  • the solution according to the invention leads to the fact that the LED board or LED boards do not need to be attached to the housing in a complicated manner and, in particular, have to be connected to electrical supply lines, but both the mechanical Holder as well as the electrical contacting is carried out in a simple manner that the boards are positioned in the housing at a suitable location and this is then assembled together. In this regard, so to speak, a wireless LED light source is realized, in which the usually complex wiring process during manufacture is avoided.
  • both housing parts are designed latchable with each other, wherein a particularly preferred embodiment may also consist in that the housing parts are pivotally connected to each other on a common side via a hinge and on the opposite side of the hinge corresponding locking means are provided.
  • the LED light source according to the invention is intended in particular to be used in luminaires that were originally designed for the use of fluorescent lamps.
  • the LED light source thus has a corresponding length, which usually exceeds the length of classic LED boards.
  • This in turn means that several LED boards must be arranged one behind the other within the receiving space. Since these boards must be electrically connected to each other, it is preferably provided that at one of the two housing parts, preferably on the second housing part, at regular intervals contacting surfaces or spring contacts are arranged, which are designed to each two adjacent LED boards electrically to each other connect.
  • the contacting surfaces or spring contacts are arranged correspondingly at least two different board lengths.
  • Another development of the invention which simplifies both the assembly and ensures a high quality light output, is to provide on at least one of the two housing parts means for the defined positioning of the LED board (s). These means may be, for example, a pin or projection, which cooperates with a corresponding recess or opening of the LED board.
  • a plurality of guide elements arranged on both sides of the LED board are preferably provided, which, while guiding the LED board, allow a relative movement with respect to the housing, so that due to different thermal expansion coefficients, resulting displacements can be absorbed or compensated.
  • the means for defined positioning may also comprise a grid, wherein it may also be provided in particular that this grid is also used for the defined positioning of optical elements in the housing.
  • optical means e.g. in the form of lenses or the like, which must be accurately positioned with respect to the LEDs in order to ensure a desired effect on the light.
  • optical means in the form of foils e.g. Scattering foils or filters are inserted into the housing to adjust the overall light output to special requirements.
  • FIGS. 1 to 7 should first be explained the basic structure of the LED light source according to the invention, then then meaningful developments or variants are discussed.
  • FIG. 1 shows this in perspective view an embodiment of a reference numeral 100 provided LED light source
  • FIG. 2 is a sectional view perpendicular to the longitudinal axis L of the LED light source 100 is shown.
  • the LED light source 100 consists of two housing parts, a first rear housing part 20 and a second housing part 40, which are connectable to each other and in the connected state, a receiving space 50 (see Fig. 2 ), in which at least one, but usually a plurality of LED boards 10 are arranged with LEDs 11 arranged thereon.
  • the second housing part 40 via which the light emission takes place, is formed at least partially permeable to light and represents the optically active element of the LED light source 100, via which the light output can be influenced.
  • the configuration of the two housing parts 20, 40 may in particular the sectional view of FIG. 2 be removed.
  • the first, rear housing part 20 serves on the one hand the storage of the LED boards 10 and on the other hand also the storage of a control gear 15 for powering the LED boards 10. It has for this purpose an elongated, plate-shaped central region 21. On both longitudinal sides of this plate-shaped region 21 run lateral projections or webs 22, which are each formed with locking lugs 23 pointing towards the inside. About this locking lugs 23 is then described in more detail below, preferred tool-free connection with the second housing part 40th As further in FIG. 2 , but especially in FIG. 7 can be seen, in this case, the first housing part 20 on the side facing the receiving space 50 side of the plate-shaped portion 21 in the longitudinal direction extending ribs or projections 25. These serve as a support surface for the LED boards 10.
  • the second housing part 40 likewise has a longitudinally extending, central region 41, which is optically effective and responsible for the light emission of the LED light source 100.
  • this central light-emitting region 41 is dome-shaped and has approximately a semicircular shape in cross section, so that the light emission surface formed in this way substantially follows the surface of a centrally divided fluorescent lamp.
  • the illustrated shape of the Lichtabstrahl Schemes 41 is merely to be regarded as exemplary and can in principle be chosen in any way to achieve a correspondingly desired light output. This also applies to the choice of material for this Lichtabstrahl Scheme 41 of the second housing part 40.

  • the inside or outside can additionally be provided with further light-influencing structures such as, for example, prism structures, facets or other structures.
  • the second housing part additionally optically active elements such. Foils, filters or the like to influence the light-emitting properties in the desired manner.
  • the means for detachably connecting both housing parts 20 and 40 could also be provided in the same way. It would also be possible in an analogous manner that corresponding webs are formed with locking lugs on the second housing part 40 and that the first housing part 20 has only outwardly facing arms which cooperate with these locking lugs. Also, the means for locking both housing parts 20, 40 may be embodied in any other form, but overall should preferably be a tool-free assembly to be made possible. Furthermore, it would also be conceivable to pivotally connect the two housing parts to one another via one or more hinges.
  • Both housing parts 20, 40 can therefore be connected to one another in a simple manner and, if necessary, also released from each other again.
  • a further special feature of the solution according to the invention consists in particular in the manner in which the LED boards 10 are arranged and electrically contacted in the receiving space 50 enclosed by the two housing parts 20, 40.
  • the peculiarity consists in the fact that the LED light source 100 is wirelessly performed and the electrical contacting of the LED boards 10 exclusively via tracks, pads and spring contacts. This essential for the present invention concept will be described in more detail below.
  • a continuous electrically conductive connection takes place starting from the operating device 15 to the boards 10 and across them and also back from the boards 10 a connection to the operating device 15 present to achieve a closed power supply circuit.
  • elongated conductor tracks 51 and 52 extending at the rear side of the first housing part 20 are initially responsible, which run away from contact surfaces 53 and 54 for the operating device 15 or extend therefrom.
  • These contacting surfaces 53 and 54 are used for the electrical connection of the operating device 15 to the internal power supply circuit for the LED boards 10, wherein the contacting takes place by means provided on the underside of the housing of the operating device 15 spring contacts 16 and 17.
  • the mechanical attachment of the operating device 15 to the rear side of the first housing part 20 takes place with the aid of a retaining clip 18, which is fixed on the one hand to the housing part 20 and on the other hand presses with a control device 15 spanning strap 19 resiliently against the rear or top of the operating device 15 and thus this presses on the first housing part 20.
  • a comparable procedure is also provided for the electrical contacting of the LED boards 10. Since these, however, generally have a shorter length than the entire LED light source 100 and thus several boards 10 are arranged in the longitudinal direction one behind the other used, additional care must be taken to ensure that the individual boards 10 can be electrically connected to each other.
  • contacting surfaces 44 are again formed on the second housing part 40, more precisely on the two upper sides of the side arms 42 facing the receiving space 50. These arranged at regular intervals, elongated contact pads 44 are intended to be contacted by the LED boards 10, for which purpose, in each case correspondingly designed spring contacts 12 are provided at the end portions of the LED boards 10 again. As in particular the representation of FIG. 6 shows, the positioning of the contacting surfaces 44 and the spring contacts 12 is selected such that two longitudinally successively arranged LED boards 10 each contact a Needlesêtsfeld 44 via the spring contacts 12, thereby the required to achieve a closed power supply circuit electrical connection of the LED Platens 10 can be achieved with each other.
  • spring contacts 55 and 56 engage over the front side of the LED board 10 and are positioned in the same way as it would be the spring contacts of a neighboring further LED board 10.
  • the intended for connection to the tracks 51 and 52 frontally mounted LED board 10 does not need to be modified in a special way but may instead be configured identically to all other LED boards 10.
  • an assembly or an assembly of the various components of the LED light source 100 according to the invention can take place in a very simple manner. In particular, no complicated steps for cabling or electrical connection of the various components are required. Instead, all the essential measures such as the application of the conductor tracks and contacting surfaces and possibly the fixing of the spring contacts on the LED boards can be done in an automated manner. The manual installation work can be kept to a minimum.
  • the positioning of the contacting surfaces 44 and the spring contacts 12 could also be reversed. In this case, therefore, 10 contacting surfaces would have to be provided on the corresponding surface of the LED boards and the spring contacts would instead be positioned on the second housing part 40. Again, however, the same advantages would result in the manufacture of the various components of the LED light source as well as the assembly in the final assembly.
  • the LED boards 10 are contacted from the back by appropriate measures.
  • the spring contacts 12 or contacting surfaces 44 would then have to be embodied on the rear side of the LED boards 10 or on the corresponding surface of the first housing part 20.
  • the embodiment as shown in the Figures 1-7 is shown, however, is advantageous in that, as usual LED boards are designed for a contact from the front side and, accordingly, can be used again on standard components.
  • the contacting surfaces 44 are designed in different arrangement patterns on the corresponding housing part, in this case the second housing part 40, so that it is possible to use LED boards of different lengths. That is, the positioning of the pads 44 is such that subgroups thereof each form an array pattern evenly spaced apart longitudinally, although a single pad may well be associated with multiple patterns. Depending on how long the boards are used, then only the corresponding suitably positioned contacting surfaces 44 are contacted by the LED boards 10, whereas those contacting surfaces 44, which are not arranged in the transition region between two adjacent LED boards 10, remain functionless.
  • both housing parts 20 and 40 are made of plastic.

  • the housing parts 20 and 40 to combine plastic with other materials.
  • This relates in particular to the realization of the first housing part 20, wherein, for example, metallic materials such as aluminum, copper, sheet metal, etc., or ceramics could be used.
  • metallic materials serves in particular the heat dissipation, while conversely speak for the use of ceramic materials, the insulating properties and the ability to apply to the ceramic materials in a simple way, the traces and pads can.
  • Another advantage is that ceramics can have a high degree of reflection and, if necessary, the efficiency of the LED light source can be increased here.
  • An improved heat coupling between the LED boards 10 and the first housing part 20 could also be achieved by introducing a separate element with high thermal conductivity into the remaining gap. It may be both plastic with improved heat conduction and a metal, which fills the space between the top of the LED board and the bottom surface of the first housing part and thus transmits the heat directly from the LEDs 11 to the back of the housing part 20 ,
  • the production of the housing parts 20, 40 can be done depending on the materials used. When using plastics and / or aluminum, it is possible to carry out the housing parts as extruded parts, possibly also with two different material components. The extrusion part can then be cut to the desired length and used either stand alone or possibly with other additional parts. These accessories may be e.g. to additional holders, which allow the attachment of the LED light source to a light carrier part, or act on end portions, which terminate the receiving space 50 at the two end sides of the LED light source 100.
