Definitions

  • the invention relates to a flashlight with an on-off switch, via the different brightness levels and / or different wavelengths of optical light can be switched.
  • LED light-emitting diodes
  • LED chips on a board are also known as so-called chip on board, even in versions in which several versions are arranged on a carrier.
  • the switch is designed as a rotary switch, which is connected to a pressure-loaded, decentralized contact spring which, depending on the rotational position, contacts at least two different contact zones in a circuit-closing manner via which different voltages can be set in the circuit and / or different LEDs can be controlled.
  • the cathode is centrally located, whereas the anode forms a disc-shaped ground contact on the opposite side.
  • One of the contact zones is formed as an isolated surface, the touching then the off state of the
  • Flashlight can be set.
  • the contact spring in each case passes through a plurality of zones relative to the center of rotation, wherein the circular segment zones can be divided into two, three, four or more zones, whereby different switching states can be created.
  • the circuit can be designed so that, for example, in a first switching stage, only one diode is turned on and then successively turned on further diodes, whereby a stepwise controllable in the brightness lamp is formed.
  • the flashlight diodes with different Strahiungsemissionsen, d. H. different color renditions to use, which can be switched alternatively or in groups.
  • each color reproduction of a single diode z. B. blue, red or orange, used.
  • the rotary switch used can be operated over a rotation angle up to 360 °, wherein in four different switching states each contact zones with a rotation angle of 90 ° are created. Between the individual contact zones there is a linear insulation layer, which prevents the contact spring from forming a short circuit with two different contact zones.
  • a battery holder or an LED holder is rotatably arranged in a lamp housing, which is actuated via a shroud as a rotary switch, which protrudes from the lamp housing or flush terminates maximally with the lamp housing.
  • the battery cartridge can be rotated within the flashlight housing, wherein the contact spring attached to the battery cartridge, which abuts, for example, the underside of a board (i.e., a disc-shaped board), is moved relative to the fixed board.
  • This board has the different contact zones and thus the different control options.
  • the battery holder as a battery cartridge can be fixedly mounted in the lamp housing and the rotary ring with the Diodenhait für, d. H. connected to the board.
  • the other contact, the battery cathode, is located centrally on the bottom of the board.
  • the jacket ring as a rotary switch can easily protrude from the lamp housing or flush with the lamp housing.
  • the contact spring consists of a bent leaf spring, a coil spring or a telescopic spring, d. H. a spring-loaded telescoping sleeve, which has the advantage that the Dmckfeder contained therein is not subjected to shear forces.
  • FIG. 1 is a side view of a flashlight
  • Fig. 2 is a longitudinal sectional view of the flashlight of Fig. 1 along the line A-A
  • FIG. 4 detail views of the cutouts C and B in Fig. 2,
  • FIG. 6 shows a schematic view of a lamp head with attachment optics, a chip on board and a battery cartridge held in a cover part.
  • the flashlight shown in the figures has a cylindrical shape with a screwable lid 10 releasably secured at the end and a front end 11 as the light exit surface.
  • at least one battery or a battery pack or a battery cartridge 13 is arranged, which accommodates a plurality of batteries connected in series.
  • the heart of the flashlight is a disk-shaped circuit board 14 with at least one LED 15.
  • Different voltages can be represented in battery cartridges, for example, by four batteries from only two serially connected batteries, the voltage is tapped. With just a single battery, the voltage can be represented by a series resistor with multiple contact points.
  • the flashlight also has an attachment optics 16, which is designed as a reflector lens, wherein the 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 of where they are also emitted in the direction of the open end 11.
  • a rotary switch is provided, which in the present case is designed as a rotary ring 19, via which the battery cartridge 13 in the lamp housing 12 can be rotated.
  • the battery cartridge 13 has in the case shown a first central spring contact 20 and a decentralized contact spring 21 which sweeps along with the rotatable cartridge below the disk-shaped board 14 different contact zones.
  • the middle contact can also be created by the positive pole of the battery.
  • the contact spring 21 can, as shown in principle in FIG. 5, contact one of the contact zones 1, 2, 3 or 4, wherein each contact zone offers different circuit options. Between the contact zones 1 to 4 respectively insulating webs 23 are arranged to prevent the false circuits by simultaneous contact of the contact spring 21 with two areas.
  • circuit options is arbitrarily large and only limited by the fact that the contact spring 21 must have a secure support with one of the created contact zones 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.

Abstract

Lampe de poche qui comporte un commutateur grâce auquel différents degrés de luminosité et/ou différentes longueurs d'onde de lumière optique peuvent être sélectionnés. Selon l'invention, ledit commutateur est conçu sous forme de commutateur rotatif relié à un ressort de contact sollicité en compression et situé de manière excentrée, qui touche, selon la position de rotation, au moins deux zones de contact différentes de manière à fermer le circuit de courant. Lesdites zones de contact permettent l'application dans le circuit électrique de tension différentes et/ou la commande de DEL différentes.
