Definitions

  • LED light-emitting diodes
  • Ex-i the type of protection Ex-i. This means that the LED is supplied via a safety barrier which limits current / voltage to such an extent that neither ignition energy nor ignition temperature is reached for an explosive mixture.
  • the maximum surface temperature of the corresponding component is also limited.
  • LEDs are known, which are designed according to the type of protection Ex-m "Vergusskapselung". This means that at least parts of the LED, which could be sources of ignition for a corresponding explosive mixture, are embedded in a potting compound. As a result, a corresponding arc can not pass through to the explosive mixture outside the enclosure.
  • GB 2428467 A discloses an explosion-proof LED module with at least one light emitting diode, a heat sink connected thereto and a LED cover covering the LED at least in the emission direction. This extends into a Einsteckverianaung the heat sink and in the insertion recess, the cover is surrounded by a potting compound sealing the LEDs relative to an external and possibly explosive atmosphere.
  • GB 2458345 A describes a sealed lighting unit with an array of LEDs.
  • the LEDs are arranged on a first surface of a printed circuit and covered by a plurality of lens elements in the emission direction.
  • US 2006/227558 A1 describes a lamp with an outer shell for dissipating heat from the light source. As light elements LEDs can be used.
  • the outer shell is inserted with its free ends in a recess at an upper end of a metallic sleeve.
  • the present invention has for its object to provide an explosion-proof LED module, in which the production is relatively simple and inexpensive from prefabricated parts in a short time.
  • the explosion-proof LED module is further distinguished by the fact that sufficient cooling is provided in accordance with the type of protection "intrinsic safety" and an embedding of the component corresponding to the type of protection "encapsulation”.
  • the solution according to the invention is characterized in that the explosion-proof LED module has at least one light emitting diode LED, a heat sink connected thereto and an LED cover covering the LED at least in the emission direction, this LED cover extending into an insertion recess of the heat sink and is surrounded in this insertion recess of a potting compound sealing the LED relative to an external and possibly explosive atmosphere.
  • Such an explosion-proof LED module is easy to manufacture and has various advantages that are otherwise known only for the realization of different types of protection for themselves, see the above statements.
  • the heat sink has at least one extending in its body longitudinal insertion recess, in which the LED board is placed on a cooling surface.
  • the cooling surface can have corresponding dimensions as the board, see length and width.
  • Directly sealed LEDs do not need to be used, and at the same time the space surrounding the LED is relatively small due to the use of potting compound, heat sink with plug-in recess and LED seal. A sufficient cooling of the LED is given, and a passage of an arc to the outside in an optionally explosive mixture is reliably prevented.
  • a corresponding explosion-proof LED module can optionally be formed with only one LED on an LED board and the corresponding parts.
  • a corresponding LED board can be used, on which a plurality of LEDs in the longitudinal direction of the board, for example, are arranged next to each other and at a distance.
  • LED boards are known per se and can be manufactured in different lengths and widths as needed.
  • RGB boards or flexible boards which are optimally adapted to the particular circumstances by their flexibility. In such flexible circuit boards also proves to be an advantage that they can be processed easily and inexpensively.
  • the realization of such an explosion-proof LED module with a plurality of LEDs is further simplified if the heat sink is likewise designed for all LEDs of the LED board. That is, it is only used a heat sink on which, for example, the board is arranged directly with the LEDs.
  • the heat sink may also be formed of multiple, in particular the same body segments.
  • board or cooling surface each have larger dimensions in length or width compared to the other part.
  • heat sink and LED board can be applied either on the cooling surface or on the board a corresponding heat-conducting foil.
  • the cooling surface in the body longitudinal direction of the heat sink can be surrounded on both sides at least in places by the Einsteckverianaung.
  • the insertion recesses extend at least along the cooling surface on both sides to this. It is also possible that also at longitudinal ends of the cooling surface, the plug-in depression is present, so that this substantially completely surrounds the cooling surface.
  • the LED cover can have a number of plug-in elements protruding in the direction of the insertion recess for attachment to the heat sink.
  • the LED board can be screwed to the heat sink. Then the protective cover or LED cover is placed and held in position and shed. To Curing the potting a corresponding holding device for the cover is removed and then held only by the potting.
  • a latching recess extending substantially perpendicular to the body longitudinal direction and extending along the plug-in recess can be formed. This means that no exact assignment between locking element and counter-locking element is necessary and even a displacement of the LED cover after engagement of the locking elements in the locking recess is possible.
  • a corresponding counter-latching element may be provided for each latching element, each of which is formed by only a corresponding latching recess which is formed substantially perpendicular to the body longitudinal direction within the insertion recess.
  • the locking elements are arranged on both sides of the cooling surface in pairs or offset from each other.
  • the insertion recess in the direction counter-latching element may have a varying cross-section and / or a direction-changing course.
  • the insertion recess increases, for example, in the direction of the latching recess in cross section.
  • the detent recess has a course which is formed, for example, in the direction of the counter-detent element in a wave-shaped, zigzag-shaped or the like.
  • a Vergussverianaung may be formed on each of the longitudinal ends of the LED board in the heat sink.
  • This Vergussverianaung can be formed with the same depth as the Einsteckverianaung, but also with a different depth.

  • the LED cover can have a protruding in the direction of insertion recess or Vergussverianaung, in particular circumferential peripheral edge. This is arranged in the potting compound arranged on the heat sink LED cover, so that the sealing of the LEDs relative to the outer atmosphere takes place substantially on the immersion of this peripheral edge in the potting compound.
  • the male members are formed separately from the peripheral edge and protrude from the remaining LED cover in the direction of insertion recess.
  • the male members may protrude from the peripheral edge.
  • the LED cover in its longitudinal direction identifies a uniform curvature for receiving all LEDs.
  • the LED cover has convexly curved LED domes from the LEDs, with one LED dome in each case being assigned to one LED.
  • the individual LED domes are formed as a lens system for the LED or include such.
  • the corresponding dome may also be formed as an optical element, for example, determines the emission of the LED, which makes the radiation of all LEDs continuous, so that the LEDs do not appear as point light sources, etc.
  • Reflective devices can also be provided within the LED cover or domes, which likewise serve to align the light, or covers or domes can have surface structures on the inside or outside which likewise influence the light output or light intensity.
  • the length of such a LED module with LED board can be approximately equal to a tubular fluorescent lamp, so that they can be replaced by the LED module are.
