Definitions

  • the invention relates to a flashlight which has a rotary switch for switching different brightness levels and / or luminous colors, which has a rotatably arranged in a flashlight housing battery cartridge with frontally arranged resiliently mounted electrical contacts, which are each connected to an electrical contact surface or an electrical contact zone of a contact plate ,
  • LED chips are known on a contact plate as a so-called chip on board, even in versions such that different LEDs are arranged on a support.
  • WO 00/45086 describes a rod-shaped flashlight with a light source at each end of the flashlight.
  • the flashlight consists of two parts that are rotatable relative to each other. A portion of the flashlight is connected to a battery cartridge, at its front side a segmented contact plate is fixed, which rests against fixedly mounted electrical contacts of the other part. By turning the battery cartridge, the electrical contacts can be connected to different contact surfaces and thus close different circuits.
  • a disadvantage of the construction described is that the flashlight parts are only plugged together and thus can be easily pulled apart, so they lose their functionality.
  • a flashlight should be made robust and function reliably even with a robust use.
  • the battery cartridge is captively held by a fixing sleeve in the flashlight housing and can be rotated by a knob in the flashlight housing, which passes through the fixing sleeve leksaxial.
  • the contact plate has on one side a centrally arranged electrical contact surface and a plurality of radially spaced-apart electrical contact zones.
  • the electrical contact surface could be ring-shaped or partially ring-shaped, it being only necessary to take into account that the corresponding electrical contact is arranged in such a way that it remains in contact with the contact surface upon rotation of the battery cartridge.
  • At least one LED is preferably arranged on the other side of the contact plate.
  • the essence of the present invention relates to a flashlight with different switching states.
  • the contact zones are connected to different electrical resistors or different LEDs, so that the choice of the circuit closing contact zone and the function of the flashlight can be determined. So that no current flow arises between the individual contact zones, the electrical contact surfaces and the electrical contact zones are separated from one another by insulating webs.
  • a spring-mounted electrical contact with the centrally disposed contact surface is electrically or contact-connected and the other electrical contact with one of the radially spaced contact zones.
  • the specific position and shape of the contact surface and the contact zones is not critical. Rather, it is important that the respective contacts are connected even with a rotation of the battery cartridge with the contact surface or the desired contact zone.
  • the battery cartridge is captively held in the flashlight housing.
  • the battery cartridge has for this purpose a rear annular abutment surface and a threaded portion, wherein the fixing sleeve has corresponding stop surfaces and a threaded portion with which it is connected to the flashlight housing.
  • the knob is over a threaded portion with the battery cartridge connected, so that the battery cartridge can be rotated about it in the flashlight housing. The knob penetrates longitudinally in the installed state, the fixing sleeve.
  • the battery cartridge has a pressure switch, which is in operative connection with a knob arranged in the knob.
  • This additional pressure switch allows the user to select the desired switching function of the flashlight when turned off by turning the battery cartridge and switching this function on via the pressure switch.
  • it can be prevented via the pressure switch, that turns on the flashlight by unintentionally turning the knob, which can easily happen, for example, when transported in a backpack or a bag.
  • the flashlight shown in the figures has a cylindrical shape with a screwable end cap 10 detachably fastened at the end, which is formed from a fixing sleeve 11 and a rotary knob 12, and a front end 13, which is formed as a light exit surface.
  • a battery or a battery pack or a battery cartridge 15 is arranged, which accommodates a plurality of batteries connected in series.
  • the flashlight has a contact plate 16 with at least one LED 17. When using a single LED 17 different colors and / or different brightnesses can be emitted depending on the voltage drop across the LED 17.
  • the flashlight also has an attachment optics 18, which is designed as a reflector lens, wherein radiation emitted in the center meet the inner collection lens part and are bundled there into parallel light, whereas the laterally emitted rays strike a cone and an outer reflector surface, from where from they are also emitted in the direction of the open end 13.
  • the flashlight has a rotary switch, which is formed in the present case by the contact plate 16, the battery cartridge 15 and the knob 12.
  • the battery cartridge 15 has a first central spring contact 20, which is electrically connected to the central contact surface 5, and a decentralized contact spring 21, which together with the rotatable battery cartridge 15 below the contact plate 16 different electrical contact zones 1,2,3, 4 passes over.
  • the contact spring can, as in principle in Fig. 5 represented, with one of the contact zones 1, 2, 3, 4 contact, each contact zone 1, 2, 3, 4 offers different circuit options. Between the contact zones 1 to 4 each insulating webs 3 are arranged to prevent the false circuits by simultaneous contact of the contact spring 21 with two contact zones.
  • circuit options is arbitrarily large and limited only by the fact that the contact spring 21 must have a secure support with one of the created contact zones 1, 2, 3, 4 in a defined circuit state.
  • flashing functions can be implemented in addition to the activation of different diodes or diode groups as well as different voltages.
  • the flashlight shown has a pressure switch 22, so that the desired switching function can also be selected in the off state.
  • the captive holder of the battery cartridge 15 within the flashlight housing 14 is in the detailed view of Fig. 4 shown.
  • the flashlight housing 14 has a threaded portion 40, via which the fixing sleeve 11 is attached.
  • the fixing sleeve 11 has a contact surface 41, which is in contact with a contact surface 42 of the battery cartridge 15 and holds it in the flashlight housing 14.
  • the battery cartridge 15 is connected via a threaded portion 43 with the knob 12, which passes through the fixing sleeve 11 longitudinal axial.
  • the push button 44 which is connected to the pressure switch 22 of the battery cartridge 15.
