  • the switching element can be activated or deactivated by a movable switching means.
  • a movable switching means for example, a magnet is conceivable, which is brought into the vicinity of a switching element, such as a magnetic switch, and thus turns on the switching element and shuts off at sufficient distance from the same.
  • a reliable tilt switch with simple components is easy to produce, in which the switching means, for example, due to gravity away from the switching element or approaches this.
  • the switching means can be movably arranged in a tube, so that the switching means can only move along a predetermined path or in a predetermined spatial area.

  • a fluid medium such as a viscous liquid or a gas
  • the tube can preferably either be arranged fixedly in the interior of the housing or be insertable into at least one recess, which is freely accessible from the outside and at least watertight, of the housing.
  • a fixed arrangement inside the housing allows a compact and maintenance-free construction of the lighting unit in the housing.
  • the tube can be inserted from the outside into the recess of the housing, it can be removed from the housing, for example for transport purposes, in order to prevent unintentional switching on.
  • the housing preferably has at least two recesses, wherein the switching element is switchable only in arrangement of the tube in one of the recesses by the switching means. Due to the fact that the switching means in the tube in the arrangement of the tube in at least one of the recess is not able to activate the switching element, these at least two recesses cause a reliable transport lock against unintentional switching on of the lamp, wherein the switching means at or in the lighting unit can remain.

The outer contour 88 of the lens body 84, however, has a serrated appearance in longitudinal section. Since the scattering lens 58 is constructed substantially rotationally symmetrical with respect to its longitudinal center axis 90, a construction of the lens body 84 accordingly results according to type a Fresnel lens, such as in the Fig. 11 and 12 can be seen. On the outer circumference of the scattering lens 58 circumferential, prism-like formations are arranged.
  • the light-emitting diode 56 is arranged on a horizontally arranged circuit board 60, which is connected to a vertical circuit board 62, on which a battery 64 and a reed contact 66 are attached.

If the tube 68 is arranged with the magnet 70 in the second recess 78, the magnet 70 is in any possible position within the tube 68 to far from the reed contact 66, so that the magnet 70 can not turn on the latter even when the light signal 20 is in the floating position. Thus, a simple and effective safeguard against unintentional switching on, as is necessary, for example, for transport and storage purposes, by repositioning the tube 68.
  • the magnet 70 Due to the downward force of gravity, the magnet 70 is located in the lower region of the tube 68, as can be seen in the figures.

If now the lighting unit 24 together with the tube 68, for example rotated by more than 90 °, for example rotated by 180 ° upside down, the magnet 70 moves by gravity to the opposite end of the tube 68 and thus moves away from the reed contact 66th so that the magnet 70 can not turn it on due to the greater distance to the reed contact 66. An overhead storage of the light unit 24, even if it is mounted in the float 22, thus ensures a shutdown of the light unit 24.
