  • the low-power LEDs and the high-power LED both separately and jointly activated.
  • different degrees of illumination can be achieved.
  • the heat baffle with a cover plate limits a space which is filled with a thermal grease. This increases the efficiency of heat dissipation.
  • a lamp having the features of patent claim 6.
  • a lamp is provided which has a high light output and in which a heat accumulation is prevented and which is also inexpensive to manufacture.

  • a charging connection socket is arranged on the lamp, which can be covered by a slide, which is movably arranged in a rail. In this way, a possibility for external charging of a battery disposed within the lamp housing is made possible, which is protected by the slider against external influences.
  • a gas sensor is arranged on the lamp, which is integrated in the lamp housing. This allows early alarming of the worker in the presence of harmful or explosive gases.
  • the invention is further based on the object to provide a method for producing a miner's lamp, which allows a high-density connection of the housing parts and thereby ensures a high-density encapsulation of the light and thus meets the requirements of the highest protection classes. According to the invention, this object is solved by the features of claim 12.
  • a method for producing a miner's lamp which enables a high-density connection of the housing parts and thus ensures a high-density encapsulation of the light insert and thus meets the requirements of the highest protection classes. Due to the high-density encapsulation in particular an uncontrolled heat leakage is avoided, which in turn can lead to hazards in connection with high-explosive gases.
  • a recess is placed on the housing, under which a switching element is arranged, and on the recess of a ring is arranged, wherein the housing and the ring are formed such that between these a gap is formed, and an elastic operating part having a peripheral edge, is arranged between the housing and ring, that the edge engages in the gap and that the operating element acts on the switching element when externally pressurized, and subsequently the ring is connected to the housing by means of plastic welding, wherein the edge between ring and housing is pressed.

  • the cover plate 14 is designed substantially circular and has in its center an inwardly directed curvature 142. In the middle, a breakthrough 141 is introduced into the cover plate 14, into which the inner curvature 142 opens. Laterally, an opening 143 for the passage of the connecting cable 124 of the printed circuit board 12 is inserted into the cover plate 14.
  • the cavity formed by the inner arch 142 and the opening 141 is closed by a circular diaphragm 15. This is a membrane that allows heat to pass through.
  • the closed by the diaphragm 15 cavity is filled with thermal grease 16,
