Definitions

  • the present invention relates to a LED lighting device, in particular a lighting device using LED filaments which are attached to an improved holder.
  • a specific type of LED lighting devices uses LED filaments, i.e. strip-like LED elements which typically comprise a plurality of LEDs arranged in a row on a transparent strip-like carrier (e.g. glass or sapphire materials).
  • the LEDs may be coated by a coating for converting the light generated by the LEDs into a desired wavelength range.
  • Multiple LED filaments are usually arranged inside a bulb of a lighting device. For ensuring a specific arrangement of the LED filaments with respect to each other and for supplying the LED filaments with electrical power a holder is needed.
  • a lighting device comprises a translucent bulb, in particular a transparent bulb, a base having at least two electrical contacts, and a light engine arranged inside the bulb.
  • the bulb can be made from glass or a plastic material.
  • the base can for example be a screw base (e.g. E14), a bayonet base (e.g. GU10), a bi-pin base (e.g. G4), or any other type of lamp base.
  • the light engine inside the bulb comprises four or more LED filaments attached to a holder.
  • the light engine may comprise 4, 5, 6, 7, 8 or any other number of LED filaments.
  • the LED filaments are arranged such that not all LED filaments are positioned parallel to each other, in order to minimize the generation of shadows.
  • the holder has a first electrically conductive holding structure and a second electrically conductive holding structure.
  • Each LED filament is connected with a first end to the first holding structure and with a second end to the second holding structure. Apart from the connection via the LED filaments, the first holding structure and the second holding structure are electrically isolated from each other. Preferably, the LED filaments are connected to the holding structures such that an electrically parallel connection (as opposed to an electrically serial connection) is obtained.
  • the first holding structure is connected to a first electrical contact of the base and the second holding structure is connected to a second electrical contact of the base.
  • the connection of the first and second holding structure to the electrical contacts of the base may either be direct (i.e. the holding structure itself is connected to the electrical contact or the holding structure is connected to an electrically conductive element such as a wire which in turn is connected to the electrical contact) or indirect (i.e. the holding structure is connected to an electrical driving circuit for driving the LEDs and the driving circuit (also known as driver) is in turn connected to the electrical contact).
  • an electrical voltage to the electrical contacts of the lamp base in turn supplies the LED filaments and, accordingly, the LEDs on the LED filaments with an electrical voltage.
  • the voltage supplied to the LED filaments is the voltage applied to the electrical contacts.
  • the voltage supplied to the LED filaments is determined by the driving circuit.
  • the holder may be supported inside the bulb by a glass stem which can be melted during manufacture of the lighting device.
  • the holder i.e. the ends of the connection sections of both holding structures, is then inserted into the molten stem. After cooling of the stem, the holder is fixedly attached to the stem.
  • the holder may comprise fixation elements at the end of the connection section of each holding structure.
  • the fixation elements can be attached to separate connectors that have been inserted into the glass stem as described above. In this case, an electrical voltage is supplied to the LED filament via the separate connectors, the fixation elements, and then the holding structures.
  • Such fixation elements are described in German patent application DE 102016117450.5 .
  • Each of the first holding structure and the second holding structure comprises an essentially longitudinal connection section and an attachment section essentially perpendicular to the connection section.
  • the LED filaments are attached to the attachments section, such that an electrical connection as well as a mechanical connection between LED filaments and holding structure is achieved.
  • the connection section connects the attachment section to the electrical contacts of the lamp base (if a driving circuit is used, indirectly via the driving circuit).
  • the connection section and the attachment section can be different parts of a single element or they can be constituted by different elements which are electrically conductively and mechanically connected to each other, for example, they can be soldered or welded together.
  • connection section and the attachment section are electrically conductive.
  • connection section and the attachment section are electrically conductive.
  • the first holding structure and the second holding structure is formed from a wire.
  • the wire is preferably made from steel, in particular stainless steel, and may be plated with nickel or another metal.
  • the wire may have a diameter between approximately 0.8 mm to approximately 2.5 mm.
  • Holding structures fabricated from such a wire are stable enough to mechanically support the LED filaments in their desired positions. Manufacturing a holding structure from a wire by bending the wire into the shape of the holding structure is easy and can easily be included in an automated production line.
  • Each holding structure is manufactured by bending the holding structure as a whole from a single wire.
  • the attachment section of the first holding structure and the attachment section of the second holding structure has a circular or a polygonal circumference.
  • the term "circular” also includes an elliptical shape or other small deviations from the mathematical shape of a circle, e.g. egg-shaped.
  • a polygonal shape includes polygons with 3, 4, 5, 6, 7, 8, or more sides. The sides of the polygon may all have the same length but may also have different lengths. The number of sides of the polygon may equal the number of LED filaments attached to the polygon. The LED filaments may be attached to a polygon at the corners of the polygon or along its sides.
  • the attachment section is formed by bending a wire into the desired, circular or polygonal, shape. Such an attachment section is particularly easy to manufacture.
  • connection section of the first holding structure and the connection section of the second holding structure has the shape of a straight line.
  • the connection section can, in particular be constituted by a straight wire. This further simplifies manufacture.
  • connection section is connected to the respective attachment section by a radial section.
  • a radial section This allows positioning the connection section at a suitable location with respect to the attachment section.
  • the connection section must not be located at the circumference of the attachment section but can also be located towards the "interior" of the attachment section.
  • the connection section can, however, also be positioned at a point along the circumference of the attachments section. In that case, no additional radial section is necessary.
  • the radial section can lie essentially in the plane of the respective attachment section or it can be arranged under an angle with respect to the plane of the respective attachment section.
  • the upper end of the connection section is at approximately the same height than the attachment section, in the latter case, the upper end of the connection section lies at a lower height than the attachment section.
  • the holder comprises a bridge element attached to the first holding structure and the second holding structure, wherein the bridge element is not electrically conductive.
  • the bridge element can in particular be made from a plastic material. The bridge element can stabilize the holder by fixing the relative position of the two holding structures with respect to each other at the position of the bridge element.
  • the bridge element comprises a front portion and a rear portion connectable to the front portion, wherein at least one of the front portion and the rear portion comprises grooves for accommodating the first holding structure and the second holding structure.
  • the front portion and the rear portion may be connected by an additional element acting as a hinge during closing of the bridge element, i.e. during attaching the bridge element to the two holding structures.
  • the front portion and the read portion may be connected by a snap fit connection.
  • connection section of the first holding structure and the connection section of the second holding structure comprises an anti-rotation portion for preventing rotation of the bridge element around the respective holding structure.
  • an anti-rotation portion may be constituted by a bend, preferably by a zig-zag bend in the wire from which the connection section is made. If the bridge element is located at the position of the anti-rotation portion, e.g., if the bend is located inside the bridge portion, rotation of the bridge element with respect to the connection section is prevented, further increasing stability of the holder.
  • Fig. 1 shows a schematic view of an embodiment of a lighting device according to the present invention.
  • An enlarged view of the light engine is shown in Fig. 2 .
  • the lighting device in this case a retrofit lamp (hereinafter referred to simply as "lamp"), suitable for replacing known incandescent lamps) comprises a glass bulb 1, a light engine 5 arranged inside the bulb 1, and a lamp base 2 with an Edison type screw base.
  • the bulb can be filled with a gas having high thermal conductivity.
  • the gas contains helium and/or hydrogen.
  • the light engine comprises a holder having a first holding structure 14 and a second holding structure 15. Both holding structures are made from a wire (e.g. nickel plated stainless steel with a diameter between approximately 0.8 mm to approximately 2.5 mm) by bending the wire into the shape of the holding structure.
  • the first holding structure 14 comprises an annular attachment section 17 which is attached to its connection section 9 via a radial section 18.
  • the attachment section 17 is arranged essentially perpendicular to the straight connection section 9.
  • the radial section 18 lies essentially in the plane of the attachment section 17.
  • the lower end of the connection section 9 is fixedly held by a glass stem 33.
  • the stem 33 comprises a flange 33a, two lead wires 33b and a glass tube 33c.
  • the bulb 2 can be evacuated and filled with a gas having high thermal conductivity through the tube 33c which is then closed by melting.
  • the second holding structure 15 comprises an annular attachment section 20 which is attached to its connection section 9 via a radial section 21.
  • the attachment section 20 is arranged essentially perpendicular to the straight connection section 9.
  • the radial section 21 lies essentially in the plane of the attachment section 20.
  • the lower end of the connection section 9 is fixedly held by a glass stem 33.
  • both holding structures 14,15 are made by bending a single wire, their production can easily be integrated into an automated production line. No soldering or welding is necessary for the production of the holding structures.
  • the completed holder is strong enough to support the LED filaments.
  • the LED filaments 12 are electrically conductively attached with their electrical contacts 13 to the attachment sections 17,20 of both holding structures 14,15, e.g. by soldering or welding.
  • the LED filaments are connected in parallel such that the LED filaments work independently from each other. Accordingly, even if one of the LED filaments should fail, the lamp is still able to operate, thus prolonging the life of the lamp.
  • Fig. 3 shows a schematic view of another embodiment of a light engine according to the present invention. Details of this embodiment are shown in Figs. 4-7 .
  • the holder of the light engine shown in Fig. 3 comprises a first holding structure 14 and a second holding structure 15.

  • a bridge 16 is attached to both holding structures 14,15 and stabilizes the holder.
  • the first holding structure 14 comprises an annular attachment section 17 which is attached to its connection section 9 via a radial section 18.
  • the attachment section 17 is arranged essentially perpendicular to the straight upper portion of the connection section 9.

  • the end of the wire runs parallel to a portion of the attachment section 17,20.
  • the end of the wire can include a S-shaped bend next the point where the attachment section 17,20 meets the corresponding radial section 18,21 so that the end of the wire lies slightly below (alternatively above, inside, or outside) the attachment section 17,20.
  • the end of the wire may be electrically conductively connected to the respective attachment section 17,20.
  • the bridge 16 is shown in an unmounted state in Fig. 6 .
  • the bridge 16 comprises a front portion 23 and a rear portion 22 connected to each other by a flexible hinge element 24.

  • the bridge 16 is made from an electrically non-conductive plastic material (e.g. by injection molding), isolating the two holding structures 14,15 from each other. Since the part of the zig-zag bend 19 of the first holding structure and the 90° bend of the second holding structure are covered by the bridge 16, rotation of the bridge 15 with respect to either holding structure 14,15 is prevented.
