Definitions

  • the present invention is based on a designed according to the preamble of the main claim lighting device.
  • Such lighting devices are generally intended to provide inside or outside of buildings for the targeted illumination of their environment, for the illumination of objects directly in their environment, for an orientation lighting and / or for a targeted coupling of light into objects. If such lighting devices z. B. for installation in ceilings, walls, floors, walkways or driveways, is often a compact design with very robust design necessary for easy installation.
  • a the preamble of the main claim corresponding lighting device is characterized by the DE 100 26 661 A1 known.
  • this lighting device a plurality of lamps are arranged on a printed circuit board, which can be connected via this to a supply network.
  • the circuit board is surrounded by a, a targeted light emission enabling housing, which protects the bulbs from aggressive environmental conditions such. As moisture, dust, mechanical stress, etc. effectively protects.
  • the interior of the lighting device is filled with a potting compound.
  • a connection cable is led out of the housing to the outside.
  • the precisely positioned fixing the circuit board in the interior of the housing is not always guaranteed reliable.
  • the use of a connection cable with respect to a reliable sealing of the housing interior against moisture and dust is relatively problematic.
  • the present invention is therefore an object of the invention to provide a lighting device in which in a simple and cost-effective manner a particularly accurate positioning of the circuit board in the interior of the housing, at the same time particularly reliable sealing of the interior against the ingress of moisture and dust on a particular long service life is ensured.
  • such a lighting device mainly consists of a plurality of light-emitting means 1 having printed circuit board 2, which is protectively surrounded by a housing.
  • the housing essentially consists of a base part 3 made of plastic and one above it arranged, the cover part 4 having intermediate part 5, whereby the housing consists of three parts. Both the cover part 4 and the intermediate part 5 are made of stainless steel, wherein the cover part 4 is connected by welding to the intermediate part 5.
  • the cover part 4 forms after installation z.
  • the outer visible surface of the housing and has in the present case a circular light exit region 6.
  • the housing is provided with a plug connection device 7, the plug contact parts 8 are on the one hand for connecting a plug connection coupling, not shown for simplicity out of the housing to the outside, the plug contact parts 8 on the other hand via a soldering process directly to tracks 9 of the circuit board 2 are connected, in particular out FIG. 2 evident.
  • the other hand, projecting into the housing interior end portions of the plug contact parts 8 are each provided with a shoulder 10 on which the circuit board 2 is supported exactly positioned so that a secure and accurate positioning of the circuit board 2 in the interior of the housing is ensured in a simple manner.
  • the connector device 7 is provided with a base part 11, which on the one hand has a screw thread for the connection of a connector coupling, not shown, and on the other hand, a piece protrudes into the interior of the housing and is also provided there with a screw thread.
  • the circuit board 2 On the circuit board 2, three designed as LED bulbs 1 are arranged, which are connected to the brightness control and / or color control with a control device. Both monochrome and multicolor light sources 1 or LEDs can be used.
  • the control device provided for the lamps 1 or LEDs is arranged entirely on the printed circuit board 2.
  • the control device can also be completely remote from the place or, on the one hand, it can be remote-controlled and, on the other hand, arranged on the printed circuit board.
  • the supply device there is the same possibility, namely to arrange them entirely on the circuit board 2 or completely remote from the place or to a part locally remote and to arrange the other part on the circuit board 2.
  • the interior of the housing with three different potting compound V1, V2, V3 is filled.
  • the light exit region 6 forming the first potting compound V1 has a comparatively high hardness and has a light-scattering effect.
  • the first potting compound V1 is filled into the housing, in which the intermediate part 5 provided with the cover part 4 is placed with its light exit region 6 upside down on a potting substrate.
  • the casting underlay contains a structuring, so that the light exit region 6 is provided on its outer surface with a light extraction structure.
  • the second potting compound V2 has a comparatively low hardness and is clearly transparent.
  • the second potting compound V2 surrounds the printed circuit board 2 with the components arranged thereon, such as lighting means 1, control device, etc., completely, so that decoupling of the printed circuit board 2 from the occurrence of mechanical loads is ensured.
  • the third potting compound V3 in turn has a comparatively high hardness and is also clearly transparent.
  • the second potting compound V2 is filled into the housing, in which the intermediate part 5 provided with the cover part 4 is placed on the base part 3 and the housing is then placed with its light exit region 6 upside down on a base.
  • the second potting compound V2 is filled over the filling opening 12 in the housing until it is ensured that the circuit board 2 is completely surrounded by the second potting compound V2.
  • the third potting compound V3 is filled into the interior of the housing until it is completely filled or the third potting compound V3 has penetrated into the filling opening 12 surrounding riser. The displaced during casting with the second potting compound V2 and the third potting compound V3 escapes air through the vent opening 13.
  • the vent opening 13 is also surrounded by a riser.
  • Both the connector assembly 7 and the filling opening 12 and the vent opening 13 are mounted or arranged on the bottom wall 14 of the housing opposite the light exit region 6.
  • a plurality of retaining lugs 15 are formed on the outer wall of the intermediate part 5, which ensure that the lighting device held positionally secure at its installation location, such as floors, walkways, driveways, ceilings, etc. remains.
  • the illumination device has a round outer contour.
  • the light exit area 6 is designed to be round and there is only a single light exit area 6 available. It also applies to the light exit region 6 that this can be carried out geometrically as desired, as well as a plurality of light exit regions 6, which are also designed in different ways.
  • the light exit region 6 is formed on the outside by the first potting compound V1, but it is just as possible to realize the outer region of the light exit region 6 by means of an additional optical disk.
  • the housing is not made as stringent in terms of tightness as in the present case, it is also possible to use a lighting device whose interior remains free of any potting compound.
  • the base 3 is made entirely of potting compound V1, V2, V3, so that a separate housing for the base 3 can be omitted entirely.
