Definitions

  • Such an LED module is for example from the DE 299 00 320 U1 in which an LED lamp with an external geometry substantially corresponding to a fluorescent lamp is disclosed.
  • the LED lamp each has an electrical connection on each of its end sides in the longitudinal direction, which can be used in conventional plug-in base for fluorescent lamps.
  • Several LEDs are arranged in rows on a printed circuit board as light sources, and furthermore the printed circuit board has reverse polarity protection in the form of a diode in order to prevent current from flowing through the LEDs in the wrong direction.
  • the LED module has at least two terminals, wherein each of the two terminals can be used simultaneously in another base of the lamp for a light source.
  • one of the two connections can also be used in one base of the luminaire for one luminous means and the other of the two connections can be used simultaneously in another base of the luminaire for a further luminous element, so that the LED module replaces two separate luminous means.
  • both the space of the at least two replaced bulbs, as well as the space normally provided between conventional bulbs can be used as a design space for the LED module.
  • a plurality of conventional lights a plurality of conventional bulbs are provided, wherein there are intermediate spaces between the bulbs, which primarily allow a heat dissipation from the individual bulbs.
  • LEDs are very small point sources of light, of which a large number must therefore be provided.
  • an improved light output can be achieved by means of the teaching of the invention, since then LEDs can be provided in the areas between the replaced conventional bulbs in the context of the LED module.
  • an insertion of the LED module in the body and in particular a fixing of the connections to the sockets for electrical connection can be done in a simple manner, at the same time via such an insertion of the LED module on the base body can be done.
  • terminal refers to the entirety of a terminal, such as the two pin contacts on one side of a fluorescent tube, or the mounting base of an incandescent lamp.
  • the connections can be used in base for fluorescent lamps.
  • the connection is designed in accordance with a connection on one side of a fluorescent lamp, namely primarily as two mutually remote pin contacts.
  • the LED module is used to replace standard fluorescent lamps with 18W to 58W power.
  • At least two ports are provided on one side of the LED module, and at least two respective ports on the opposite side of the LED module, respectively.
  • the corresponding connections are provided primarily at the corresponding position on the respective opposite sides of the LED module. That is, the respective terminals are arranged symmetrically to a central symmetry plane parallel to the opposite sides in the LED module.
  • the LED module has a length greater than height and width, with the terminals provided on the end sides in the longitudinal direction.
  • several parallel fluorescent tubes can be replaced by the LED module, especially two parallel fluorescent tubes.
  • the LED module is preferably at least twice as wide as it is high.
  • additional fastening means may also be provided on the LED module and / or on the corresponding luminaire, so that the LED module can be fastened additionally or exclusively in the luminaire.
  • only some of the terminals are designed to be live. Since the LED module replaces several bulbs, it is not necessarily dependent on the power supply of each bulb. Thus, it is sufficient if the power is supplied via only one connection.
  • one terminal may represent a positive pole of a DC voltage, and the other terminal the negative pole of a DC voltage.
  • connections are arranged at two opposite end sides in the longitudinal direction of the LED module in each case at the same height and at the same distance from the center in the width direction of the LED module.
  • At least one terminal of the LED module is associated with a rectifier device, in particular with associated safety circuit.
  • the rectifier device ensures that a wrong insertion of the LED module is not possible, since both directions of insertion are possible due to the rectification.
  • the safety circuit can in this context, for example, prevent too high voltage spikes or the like.
  • pin housings for providing the terminals and in particular the pin contacts can be arranged at the ends of the LED modules.
  • the LED module is characterized in that it can be used in the correct orientation in the lamp. This can be achieved, for example, by indicating the correct orientation with an arrow or a marker. On the other hand, however, it is also possible to provide a geometric limiting element, for example in the form of a projection, which prevents a wrong insertion of the LED module.
  • the electronic ballast is designed to provide a supply voltage in the correct polarity for the LEDs, regardless of the orientation in which the LED module is inserted into the lamp. This is particularly necessary for applications in which the supply voltage has already been converted to DC voltage, and the electronic ballast in the LED module merely ensures a further adaptation or securing of the current flow in the appropriate direction for the LEDs. In particular, this can be achieved by the provision of a diode.
  • LEDs may be arranged longitudinally on a printed circuit board in the LED module. This allows for easier provision and easier control of multiple LEDs.
  • the LEDs in the LED module radiate at least partially in the direction of a reflector, which reflects and scatters the light of the LEDs, so that the light field of the lamp is uniformly formed.
  • the reflector may be part of the luminaire or part of the LED module.
  • the LED module may have an electronic ballast, so that the base of the conventional bulbs and the base of the LED module can be operated with the same electrical supply.
  • the pedestals for the plurality of conventional bulbs and the at least one pedestal for the LED module are arranged so that the LED module, after replacement of the conventional bulbs, at least partially replaced in the area of each Conventional light source is arranged.
  • the corresponding base of the lamp may have a locking device for locking the terminals or pin contacts used in the base.
  • Such locking device is for example a rotary lock, a latching mechanism or the like.
  • FIG. 1 a conventional explosion-proof lamp 1 is shown, which has a base body 2, which is provided in operation with a transparent or translucent cover, which is not shown.
  • the base body 2 has explosion-proof electrical supply connections 3, 4, to which corresponding supply lines can be connected.
  • a not separately shown electronic pilot control is provided which provides a supply voltage which is suitable at least for the operation of the fluorescent tubes 5.
  • a plurality of LEDs 14 are arranged on a printed circuit board 15 in the longitudinal direction.
  • a printed circuit board 15 in the longitudinal direction.
  • the LEDs on a circuit board in FIG. 2 visible, on the other side in the width direction B further LEDs are arranged symmetrically thereto.
  • a further LED row can be arranged between the two above-described LED rows.
  • the LEDs 14 are supplied with a DC voltage, which is advantageously generated by an electronic ballast, which is provided in the LED module 9.
  • the LED module 9 can be inserted into the main body 2 of a conventional luminaire 1, which provides a supply voltage for a fluorescent tube by means of an electronic ballast.
  • the LEDs 14 are largely upwardly and to the side surrounded by a reflector 16 or more reflectors 16, which direct the light in the direction of the opening of the base body 2 down and continue to scatter the light generated selectively by the LEDs 14. This can be achieved with the LED module 9, a similar light distribution as conventional fluorescent tubes 5.
  • FIG. 3 is again a lamp 1, which has a base body 2, wherein on the base body 2, a cover 17 is arranged.
  • this cover 17 is removed from the base body 2, either the illustrated LED module 9 or the fluorescent tubes 5 can be inserted into the base body 2 before the cover 17 is closed again.
  • This can be changed at any time, the type of light bulb of the lamp 1, without requiring a modification in the body 2 of the Lamp 1 must be performed.
  • This is particularly advantageous for use in explosion-proof lights 1, since these would require a replacement of a pilot control device in the main body 2 or the like, a new certification or safety inspection, which would be expensive and expensive to perform in the field of application of the lamp 1 in an industrial environment.
  • the LED module 9 can be designed so that it is suitable for existing luminaires 1 for replacing the fluorescent tubes 5.
  • already installed in the industrial sector lights 1 can be upgraded, so that they have LEDs instead of fluorescent tubes as lighting.
  • the terminals 10, 11 are provided on the end side 18 in the longitudinal direction of the LED module 9, the terminals 12, 13 on the opposite end side 19 in the longitudinal direction.
  • the terminals 10, 11, 12, 13 each have two pin contacts 20, 20, as shown for terminal 10, which essentially correspond in their geometry and spacing to the pin contacts 21, 21 of a fluorescent tube 5.
  • the pin contacts 20, 20 of the LED module are only partially used to power the LEDs, the other pin contacts can also be provided only for mounting the LED module 9.
  • FIG. 4 shows a schematic diagram of an LED module 9, in which essentially the two circuit boards with LEDs 14, see also FIG. 2 , are arranged parallel to each other. At one end of each board is a plus pole and at the other end a minus pole. At the ends of the LED module pin housing 22, 23 are arranged, which hold the corresponding terminals 10, 11, 12, 13 and associated pin contacts. Between the terminals and the respective circuit boards 9 rectifier means 24 and 25 are arranged at least at one end of the LED module. These preferably contain a safety circuit.
  • the rectifier devices Through the rectifier devices is also a reverse insertion of the LED module in the corresponding sockets of the lamp, see FIG. 2 , possible without damaging the LEDs due to incorrect voltage polarities. That is, through the Rectifier devices 24, 25 ensures that the respective positive pole of the respective printed circuit board with LEDs receives a positive voltage and the corresponding negative pole receives a negative voltage.
  • an LED module is thus proposed, which can completely replace existing fluorescent lamp solutions without wiring, mechanics, see, for example, socket and socket, the corresponding lamp must be changed.
  • the corresponding lamp must be changed.
  • the electrical or electronic ballast of the lamp is used.
  • the module can also be used rotated by 180 ° in the lamp and can also be operated in this position. That is, there is a non-directional operation both electrically and mechanically.
  • one LED module replaces two standard fluorescent lamps.
  • a plurality of printed circuit boards with LEDs are arranged one behind the other, also in a corresponding additional parallel arrangement, so that, for example, each two printed circuit boards with LEDs in series and parallel to each other in an LED module can be arranged. This also applies analogously to more than two printed circuit boards.
