Definitions

  • the invention relates to a flashlight with a light source and with an on the lamp housing arranged spring-loaded pressure switch for on and Turn off the light source, in particular one or more light emitting diodes (LED).
  • LED light emitting diodes
  • the LED is displacing more and more conventional light bulbs This can be explained, in particular, by the fact that an LED has a significantly longer service life as a light bulb has, an LED much less sensitive to shocks, Blows and vibrations is and finally a much lower power consumption Has.
  • the light emitting diodes available on the market emit emission spectra which are either essentially monochrome or even white.
  • the low volume of an LED allows flashlights with Such a light emitting diode are equipped to build small volume.
  • the flashlight size is substantially the size of the diode when using a diode Batteries and the required voltage depends on the number of batteries certainly. Meanwhile, flashlights have become known in which Lamp head three or more light emitting diodes are arranged, what the available standing light intensity increased significantly.
  • the flashlight to DE 200 11 282 U1 remedy that on the outer jacket, a clip that covers the push or push switch against unintentional actuation, is provided to release the push or push switch solvable, rotatable or displaceable is attached to the housing jacket.
  • a clip that covers the push or push switch against unintentional actuation, is provided to release the push or push switch solvable, rotatable or displaceable is attached to the housing jacket.
  • the clip is in each case again guided into the position covering the pushbutton or push switch.
  • the pressure switch to the contact closure when switching on takes a position at which he below a through the The lateral surface of the lamp housing lies at a certain level, which is the pressure switch surrounds.
  • the pressure switch protrudes from the lamp housing but has a "free path" around which it can be depressed without the switch engages and thereby closes the circuit. Tangential or radially over a large area acting on the outer surface of the flashlight housing Forces can not therefore cause the flashlight to turn on accidentally to lead. For this it is necessary that by means of a finger or thumb tip of the Pressure switch is further depressed, d. H. below a level through the lamp housing outer surface is determined.
  • the pressure switch preferably arranged in a switch housing, which in a slot-shaped Recess of at least substantially the lamp housing inner jacket mounted or mounted to a suitable switch carrier.
  • the switch carrier is on his the Batterieschubfach the lamp housing facing side with a pole piece covered with the battery or the batteries in electrical contact stands.
  • the pole plate thus serves as a conclusion of the switch carrier.
  • the switch carrier is preferably made Plastic and has electrically conductive pins, cables or conductors to the electrical connection to the pole plate on the one hand and to a circuit board on the other on which the LED is or are arranged.
  • the board then forms the "front" end part for the switch carrier, so that the switch carrier with switch, Board and pole sheet form a fixed unit, which after another preferred embodiment is arranged in the lamp head.
  • the switch head is convex on its upper side, wherein whose top vertex at the contact closure to turn on below the lies through the lateral surface of the housing certain level.
  • the lamp head will be both part spherical formations as well understood other rotationally ellipsoidal forms.
  • the switch carrier and the pressure switch can be unscrewed Head part of the lamp housing may be arranged, wherein the battery compartment housing cup-shaped and hollow cylindrical and formed at its upper edge of the jacket having a thread for engaging in a thread of the head part.
  • a flashlight can form strictly cylindrical, with the rear Front side is closed and the front end face a light exit opening having.
  • the switch carrier and the Pressure switches are integrated, unscrewed, removed the battery or the battery pack, then, after replacing the batteries, the head part and the rest Lamp housing be screwed together again.
  • an optical lens disposed at its, the LED facing Side has a recess into which protrudes the LED.
  • This optical Lens serves to bundle the light emitted by the light emitting diode.
  • the optical lens is in much stronger Dimensions than conventional convex lenses, which are spaced from the LED are ensured that virtually no radiation losses occur, and thus a optimal luminosity of the flashlight even with only one diode as light source is guaranteed.
  • I the optical lens as rotationally symmetric formed cup-shaped converging lens.
  • a further increase in the luminosity of the flashlight results when the optical Lens at its light exit side, i. facing away from the recess Side has a further central bore whose diameter about the LED diameter equivalent. This hole ends in front of the recess into which the Light-emitting diode protrudes.
  • a translucent plastic is preferred. especially acrylic glass, used.
  • the optical lens has a conical outer shell, which can also be mirrored, so that further light losses be avoided.
  • each optical diode can precede an optical lens, wherein the optical lenses can also form a one-piece body.
  • the flashlight shown in Fig. 1 has a cylindrical lamp housing 10, which is composed of a battery compartment housing 11 and a lamp head 12, which are screwed together via a thread.
  • a pressure switch 13 is arranged in the lamp head 12; over the LEDs 14, in the present case six light-emitting diodes, can be switched on and off.
  • a holder 15 is inserted with a plurality of batteries, which are the for the lamp operation supplies necessary voltage.
  • the pressure switch 13 is arranged in a switch housing 16, the again in the mounted state in a slot-shaped recess of the Lamp housing inner jacket of the lamp head 12 adapted switch carrier 17th is mounted.
  • the switch carrier 17 is at its the battery drawer of the lamp housing part 11 facing side covered with a pole plate 18, with the used battery or the batteries in electrical contact.
  • the switch carrier 17 is made of plastic.
  • a connecting wire 19 and a connection cable 20 serve as electrical connection of the switch housing 16 with the pole plate 18 on the one hand and a circuit board 21 on the other hand, which has a ground plate 22 and front side with six light emitting diodes 14 is equipped.
  • the said parts 13, 14 and 16 to 22 form a unit which can be inserted completely into the lamp head 12 is, which has an opening for the implementation of the pressure switch 13.
  • the Pressure switch 13 is mounted and formed in the switch housing 16 such that depression of the pressure switch only then to the contact closure, d. H.
  • the Turning the LEDs 14 performs when the pressure switch or its upper Vertex lies in a plane below that through the outer surface the lamp head 12 is certain level. This measure prevents that by external surface pressure of the pressure switch unintentionally is actuated and thus the LEDs are switched on unintentionally.
  • the pressure switch is convex on its upper side and can with a thumb or index fingers are depressed until it is in its on or off position locks.
  • the embodiment of Fig. 4 and 5 differs from the above Flashlight characterized in that only a single light emitting diode 14 is provided as a light source is, which protrudes into a recess of an optical lens 23 as a converging lens.
  • This optical lens 23 has a conical outer shell 24, which optionally can be mirrored.
  • the optical lens 23 has the light exit side a bore 25, which preferably ends in front of said recess.
  • the optical lens 23 is made of a plastic, preferably of acrylic glass.
  • the optical lens 23 is rotationally symmetrical formed and has a largest cone diameter, the Inner diameter of the lamp head corresponds.
  • the optical lens 23 is included their rear end on the board 21 and extends forward to the ring 26 as Part of the lamp head 12.
  • optical lenses When using several light emitting diodes can in a corresponding manner several optical lenses are used, each having a recess, in which protrudes the associated light emitting diode.
  • These collection lenses can be as one piece Formed attachment body.
