Definitions

  • the invention relates to a method for producing a lighting fixture based on LEDs, in particular as a light source replacement for a fluorescent lamp.
  • fluorescent lamps are used for lighting purposes in addition to conventional incandescent lamps, which are also referred to as fluorescent tubes. They work on the principle of the gas discharge lamp and are usually distinguished from simple light bulbs by a higher economic efficiency. The dimensions of such fluorescent tubes are standardized. Fluorescent tubes are usually offered in different lengths. Basically, fluorescent lamps are characterized by a relatively long life. However, this is significantly reduced with frequent switching operations.
  • LED functional bands usually consist of a flexible carrier tape on which a plurality of light-emitting diodes and further electronic components are arranged. Such light-emitting diode bands can be separated at discrete locations, so that then the desired contacting can take place.
  • an LED luminaire based on such an LED functional band, which has a housing in which the LED function band is arranged. The housing is filled with a transparent potting compound, so that the LED function band is embedded in the potting compound. In addition, the housing can be filled with a second, opaque potting compound, which forms a housing cover.
  • This LED luminaire should also be used as a replacement for existing fluorescent tube luminaires. However, the production of the lamp is also relatively expensive.
  • the invention has for its object to provide a simple and economical method for producing a lighting fixture based on LEDs, in particular LED lighting fixtures are to be produced, which can be used as a lamp replacement for conventional fluorescent lamps.
  • the invention teaches a method for producing a lighting fixture based on LED, in particular as a lamp replacement for a fluorescent lamp, wherein a populated with a plurality of LEDs LED function band in an extrusion device continuously to form an LED strip in at least one thermoplastic Plastic is embedded, wherein the LED strip is then divided into several LED strips of predetermined length and wherein one or more terminal adapters are attached to one or both ends of an LED strip.
  • Equipped LED function band means a carrier tape which z. B. at predetermined intervals with a plurality of light emitting diodes (LEDs) is equipped and which is also equipped with running in the longitudinal direction of the carrier strip traces and beyond with electrical or electronic components, which are required in the usual way for the operation of the LEDs.
  • LED functional bands are basically known in practice, they are usually operated with a supply voltage of 12 V or 24 V (DC).
  • Such LED functional bands are embedded in at least one thermoplastic by extrusion.
  • the invention is initially based on the recognition that, as it were, "endless” LED tapes can be produced continuously by means of plastic extrusion, wherein basically conventional LED functional tapes are embedded in at least one thermoplastic material in the course of the extrusion become. From such "endless” LED strips can now easily produce lighting fixtures that can serve as a luminaire replacement for a fluorescent lamp by the LED strip is divided into a plurality of LED strips in a predetermined length.
  • the LED strips produced in this way can easily be provided with connection adapters, so that the LED strips thus produced with the adapters can easily be used as a lighting fixture. In particular, it is not necessary to mount individual LEDs or LED strips in a housing.
  • LED function bands forming the starting point can be produced endlessly in advance with a desired assembly and distribution, that is to say the so-called "piercing points" are set up so that LED strips of the desired length can be produced.
  • Double-capped fluorescent lamps have hitherto been covered by the DIN EN60081 standard and single-capped fluorescent lamps of the DIN EN60901 standard. It is therefore within the scope of the invention, the lighting fixture with the proviso that the standard there fluorescent lamps are readily replaced, so that the lighting fixtures according to the invention can thus be mounted in pedestals or sockets, which are designed for the fluorescent lamps described in these standards.
  • fluorescent lamps can be replaced on a large scale without costly retooling. This is especially important if z. B. in the commercial sector fluorescent lamps are mounted on a large scale, z.
  • the lighting fixture produced in the manner according to the invention is thus characterized by high flexibility.
  • the LED strip is particularly preferably produced continuously by way of co-extrusion with at least one transparent core layer of a first transparent plastic and at least one transparent-scattering front layer of a second plastic.
  • the invention is based on the (basically known) knowledge that, in particular with elongated luminous bodies, a "homogeneous" illumination is desired without the individual light-emitting diodes being discernible as discrete luminous dots. Consequently, the transparent-scattering front layer, as if it were a scatter layer or leveling layer, ensures that the luminous element has a uniform radiation characteristic over the length and width, without the individual ones LEDs can be perceived by the viewer as point light sources.
  • the transparent-scattering front layer can be a layer which is opaque as it were.
  • the transparent-scattering character of the front layer can also be influenced by the geometric design and in particular the surface design.
  • the front layer may have a structured and / or profiled surface, wherein such a surface further enhances the deliberately desired scattering effects and consequently likewise leads to a homogeneous emission characteristic. In practice, it will be preferable to choose a combination of material selection on the one hand and geometry on the other hand.
  • the lighting fixture is ultimately composed essentially of the separated LED strips and the end-mounted adapters and that the LED tapes consequently do not have to be used in a complex manner in a separate housing.
  • the already mentioned dimensional stability of the LED strip can be advantageous.
  • the LED strip is therefore particularly preferably produced continuously by way of coextrusion with a stabilizing base layer consisting of a second or third plastic which is additional to the core layer and possibly the front layer.
  • This rear base layer thus forms a stable base housing, which, however, by way of coextrusion integral with the entire LED strip is manufactured.
  • the base layer is primarily intended to ensure the stability of the LED strip produced in this way, with the result that the LED strip subsequently actually does not can install further processing steps and in particular without the use of another housing or other housing components. Consequently, while the transparent core layer preferably consists of a highly transparent plastic and the optionally provided transparent-scattering front layer also consists of a transparent or opaque or at least partially transparent material, it is generally not necessary to manufacture the base layer from a transparent plastic.
  • the base layer is made of a non-transparent plastic. This also makes it possible to influence the radiation characteristic, in particular when it is desired to dispense with lateral and / or rear-side radiation.
  • the base layer may, in addition to the core layer of a first plastic form an additional, second layer of a second plastic. If a front layer is provided in addition to a core layer, the base layer forms an additional layer of a third plastic.
  • an elastomeric or flexible material may be used for the transparent core layer.
  • the transparent core layer it is particularly appropriate for the transparent core layer to use a plastic material with a relatively low softening point or melting point, so that the LED functional band is embedded in the course of plastic extrusion in a melt having a temperature of less than 150 ° C, preferably less than 140 ° C, more preferably up to 130 ° C. In this way, damage to the LED function band and in particular the electronic components are avoided.
  • the transparent core layer is preferably made of a highly transparent plastic, for. B. polyurethane (PU or TPU).
  • the front layer can basically be made of the same material as the transparent core layer. It can also be used polyurethane. Alternatively, the front layer can also consist of polycarbonate (PC) or PMMA.
  • the base layer is preferably made of a luminaire supporting the dimensionally stable plastic. Polycarbonate or PMMA can also be used here. It is also possible to use plastics with a higher softening point or melting point for the base layer, in particular if the arrangement ensures that the sensitive components of the LED functional strip do not come into contact with this hotter melt.
  • the base layer can also consist of PU.
  • the plastics used are processed at significantly different temperatures, it may be expedient to embed the LED functional band completely in the core layer, which is usually extruded at relatively low temperatures.
  • Other parts of the LED function band eg. B. the area of Carrier tape, for example, can be embedded in the stable base layer.
  • the optionally provided base layer forms, as it were, a housing produced in one piece with the lighting fixture.
  • the base layer is formed in a trough-shaped or funnel-shaped cross-section so that the base layer surrounds the core layer to form obliquely and / or curvedly extending boundary surfaces (in regions).
  • the base layer may thus form a trough or funnel, in which the LED function band is arranged at least partially and which is filled as it were with the transparent core layer, although the production takes place simultaneously and integrally by way of coextrusion.
  • the depression formed by the base layer, in which the core layer is arranged is closed on the front side by the transparent-scattering front layer. Also, this is - as already explained - produced by coextrusion in one piece with the other components.
  • the LED strip produced in the described manner can basically have different cross-sectional shapes. So z. B. a rectangular cross-sectional shape with a substantially planar front surface conceivable. However, it is optionally also within the scope of the invention if the LED strip has a convex (outwardly) curved front surface which is formed, for example, by a convexly curved front layer. In this embodiment too, the LED strip or the LED strip as a whole may have a substantially rectangular cross-sectional shape, but with a curved front layer.
  • the LED strip or the LED strip may also have a circular or circular segment-shaped cross section or else an annular or ring segment-shaped cross section.
  • These cross-sectional shapes have the advantage that they can coincide, for example, with the known cross-sectional shapes of conventional fluorescent tubes, so that the end caps can be adapted in their dimension to the usual plug.
  • the LED function band is embedded in a bent around its longitudinal axis state in the plastic, wherein the LEDs are then preferably aligned with the center of curvature.
  • the core layer is curved and thus formed in cross-section annular segment, wherein on the center of curvature inner side facing a curved front layer may be arranged, which has the already described scattering properties.
  • the LED strip is formed only by such a curved core layer with a likewise curved front layer arranged thereon.
  • the core layer is made of a sufficiently dimensionally stable plastic.
