Definitions

  • the present invention relates to a lighting device having the features of the preamble of claim 1 and a board carrier for such a lighting device.
  • a luminaire usually comprises a luminaire housing to which at least one lighting device or lamp can be attached by means of corresponding sockets and / or holders.
  • Conventional lighting devices are, for example, light bulbs and fluorescent tubes.
  • more and more lighting devices are used, which have several LEDs as the light source.
  • LEDs stands for light emitting diode.
  • LEDs in the present context should also include OLEDs, where OLED stands for organic LED.
  • LEDs are usually mounted on a circuit board, the respective board then carries several LEDs.
  • the operation of LED-based lighting devices also generates heat that must be dissipated in order to maximize the life of the LEDs.
  • the respective circuit board can be fastened to a board carrier, via which the accumulating heat can be slid off.
  • the heat transfer from the respective board to the board carrier In order to achieve the highest possible heat transfer between the board and board carrier, a relatively high effort can be operated. For example, it is possible to arrange a thermal paste between the board and the board carrier.
  • the attachment of a planteleit für and / or the setting of screws is associated with a relatively high cost.
  • a generic lighting device is from the US 2013/0050999 A1 known. It has an elongated and rectilinear board, which carries several LEDs on its front side, and an elongate and rectilinear board carrier, to which the respective board is attached.
  • the board carrier has a holding area for receiving the board.
  • the platinum carrier has along opposite longitudinal sides of the respective holding region retaining elements which are plastically deformed for attaching and pressing the respective board on the platinum carrier, so that they each overlap a longitudinal side edge of the respective board.
  • the respective holding element has a gripping area encompassing the respective longitudinal side edge of the board and a forming area connecting the gripping area with the platinum carrier, the plastic deformation of the respective holding element for fixing the respective board on the board carrier being largely in the forming area.
  • the back of each board is just designed.
  • the respective holding element has the same wall thickness in the gripping area and in the forming area.
  • the present invention is concerned with the problem of providing for a lighting device of the type mentioned or for an associated board carrier an improved embodiment, which is characterized in particular by a reduced manufacturing cost.
  • a possible efficient heat transfer between the respective board and the board carrier is to be realized.
  • the invention is based on the general idea of equipping the plate carrier on the respective holding region with holding elements which laterally or peripherally overlap the respective plate by plastic deformation and press against the holding region. At the same time, the respective board is thereby fixed to the board carrier.
  • the plastic forming of such holding elements can be realized particularly simply and thus inexpensively. At the same time an intensive heat transfer is made possible by the pressing of the board against the holding area.
  • the holding elements of the respective holding region can be formed by at least two holding webs, which lie opposite one another on the longitudinal sides of the respective holding region and which extend uninterruptedly along the respective longitudinal side.
  • a line-shaped depression of the printed circuit board in the respective section of the longitudinal side edge against the holding region of the platinum carrier can be generated, which improves the heat transfer.
  • the board is designed to be straight and oblong, the pressing of the board on both longitudinal side edges against the holding area causes the board is also pressed against the holding area between these longitudinal side edges, whereby a particularly intense heat transfer between the board and platinum support can be achieved.
  • the line-shaped depression of the board by means of such holding webs thus differs significantly from a punctiform depressions that can be realized for example by means of screws.
  • the respective retaining web may extend at least from one transverse side edge or longitudinal end of the respective board to the other transverse side edge or longitudinal end of the respective board.
  • the two opposite holding webs extend at least over the entire length of the respective board.
  • the two, opposite holding webs extend over the entire length of the platinum carrier. If two or more boards are arranged one behind the other in the longitudinal direction of the board carrier in the respective holding area, all boards can thus be fixed to the board carrier and biased by means of the two continuous holding webs.
  • the respective holding element may be integrally formed on a body of the platinum carrier having the respective holding region.
  • the holding elements and in particular the holding webs thus no separate components that need to be attached to the board carrier.

  • a wall thickness of the respective holding element measured transversely to the longitudinal direction of the platinum carrier is smaller in the forming area than in the gripping area.
  • the rear side of the respective board is designed to be planar, while the holding area is provided in cross-section with a convex curvature towards the board, which leads to a corresponding deflection and curvature of the board due to the edge-side depression with the retaining elements.
  • the board can be pressed against the holding area with respect to its cross section in a central region with increased pressure force, which there improves the heat transfer. Due to the relatively high rigidity of conventional board materials, a small or weak curvature with a large radius of curvature suffices for a sufficient surface pressure.
