Definitions

  • the invention relates to LED lighting according to the Preamble of the main claim, in particular LED lighting with a number of light-emitting diodes Boards and at least one, the boards to each other and cable connecting to the voltage source.
  • a lighting system especially for illuminating Signs, labels and letters with an inner Illumination is already from DE A1 100 52 380 known, which describes a low-voltage lighting system, with the individual boards with fasteners to the desired locations within the letters to be brought.
  • the disadvantage of this system is the limited Number of diodes that are connected in series can, with a series resistor for each series connection or an electronic circuit for keeping constant of the current must be provided.
  • the invention has set itself the task of a easy to install, universally applicable, rainproof, luminous system to create that simple and can be quickly installed anywhere.
  • one essentially transparent sheathing advantageously several LEDs on individual boards this transparent and essentially waterproof.
  • e.g. 150 LEDs combined in one tube become. Possibly moisture penetrating at the ends can already by self-heating of the LEDs be evaporated again and leak. As insulation is e.g. a shrink tube is absolutely sufficient.
  • the Construction depth of bodies to be illuminated e.g. letters a neon sign because of the lower heat emission and reduce the size of the lighting according to the invention; finer details can be illuminated and by laying several loops of the hose closer together the light intensity can be increased easily and cheaply.
  • the lighting is easy to install and the previous one approval law to be observed for neon crystallization Requirements for over 1000 volt systems are completely eliminated.
  • the lifespan is increased significantly, to 15-80,000 Hours, but then not with complete failure but a slow decrease in brightness is to be expected.
  • hose as a coating use whose inside diameter is larger than that Circuit board is advantageously a shrink tube, which, by heating, clings to the circuit board and with it loses its originally round shape and thus one flat mounting surface on the back of the boards, opposite the LED offers.
  • the individual boards are marked by a Cable connected to an inner strand or wire owns that to the conductor tracks on the boards connected.
  • the sheathing of the line but can also be made in one piece with the substantially transparent Coating of the light-emitting diodes are manufactured, so that there is no need for a shrink tube that otherwise over the possibly provided sheathing of the line and especially the circuit boards overcoated becomes.
  • Repair is possible by replacing individual diodes, also the subsequent covering of heat shrink tubing about the repair center.
  • LED lighting arises in the area of the boards, so that these, for example Can be attached using double-sided adhesive tape are, the LED light substantially vertical to the mounting surface lights up.
  • a certain lighting effect is at an angle to the side when illuminating letters entirely desirable thanks to internal LED lighting.
  • This scattering effect can be caused by stored Scattering particles reinforced in the transparent coating or by colored particles or coloring in their color can be changed.
  • fluorescent components in the casing have proven to be advantageous because this the punctiform light character of the light emitting diodes decrease and create a larger luminous area. At the same time, the color can be significant in this way to be influenced.
  • the diodes are not low voltage operate in the range from 10 V to a maximum of 50 V, but with a mains voltage of 220 V or even that maximum possible "low voltage" of 990 V.
  • Rectification creates a DC voltage of approx. 300 V or 990 V, so that up to 470 (red / yellow 2.1 V) or 275 blue / green / white diodes (3.6 V) in a diode tube can be accommodated.
  • the ballast should suit the case the rectified high voltage 990 V and a constant Diode current of, for example, 50 mA a power of 50 W. In the preferred embodiment for 220 V results in a correspondingly lower output.
  • a Z-diode is connected in parallel to each LED.
  • the ballast can be operated manually using a potentiometer or a control can be dimmed to "zero".
  • the tube between two diodes can be used for lighting be separated.
  • a connecting cable which is connected via a terminal is a simple one Connection to both hose ends of the further LED lighting hose.
  • the preferred embodiment shown in FIG. 1 with a shrink tube drawn over the board consists of LED boards spaced approximately 4 cm apart, which are provided essentially at right angles, but with omitted outer corners, in a tube, for example in a letter 'a' is arranged.
  • the LEDs which emit essentially upwards in a narrow cone of light, are fastened on circuit boards which are surrounded by the transparent sheathing in the form of a sprayed-on cable sheathing or in the form of a shrink tube or otherwise transparently sheathed.
  • the conductor tracks 14 branch thereby from the conductor tracks to the LED diode to one Z-diode, which is connected in parallel with the LED diode.
  • the Zener diode is on one side of the LED diode on the Circuit board arranged on the side next to the LED diode. On the opposite side, however, is the board large in size to none, the straight arrangement at the Fixing disturbing, one-sided symmetry of the boards to get in the hose.
  • the boards are with a length of approx. 10 mm and a width of 5 mm compared to the z. B. 2 mm diameter cable with sheathing significantly wider be so that the heat shrink tubing, which when heated tightly creates these as thickenings in the diode tube left clearly recognizable. If necessary an additional one before heating the shrink tube Jacket can be sprayed onto the diode or injected into the - possibly not yet shrunk - hose become.
  • the distances of the board to each other on the one Connecting voltage source cables so chosen that with a radiation angle between 90 and 150 ° (preferably 115 to 125 °) in 6 cm depths Illuminants a uniform illumination a windshield is possible.
  • width of a lighting fixture is larger than 4 cm (width of a leg to be illuminated in FIG. 1) proposes the essentially transparent, tubular casing 20 of the light emitting diodes 16 to lay the boards 10 in two rows.
  • the substantially waterproof casing 20 of the Light-emitting diodes make it easier to illuminate the body shape, the sheath 20 more than one board 10 and also the links between neighboring Luminous elements can cover.
  • the sheathing is a shrink tube the flat character of the boards remains preserved and subsequent seals are not a problem.
  • Suitable material of the casing 20 or embedded fluorescent substances can be used instead of or in addition body to be illuminated for colored interiors Create color effects.
  • a DC voltage supplying mains voltage can also be used dispensing ballast with in the to be illuminated Bodies are integrated, enough remains Place in front of and next to such a so-called converter to a to achieve uniform illumination.
  • Circuit protection is provided by Z diodes 18, which too each LED are connected in anti-parallel, guaranteed. These are preferred just like the cable 12 that is connected to a wire or a strand 11 to a conductor 14 the board is soldered, provided on this board.
  • the shape of the circuit board 10 is an essentially rectangular, with its longitudinal extension corresponding to the extension of the cable connected to this circuit board chosen, the corners of which form an oblong octagonal Board are removed.
