Definitions

  • the present invention relates to a headlamp.
  • Headlights are generally known and are often used during activities worn where a user's field of vision is illuminated must, but at the same time needs the hands for other activities. Typical fields of application are caving, Mountain sports, running training or repairs, for example on motor vehicles in the dark.
  • Such headlights often have a rigid support element on which the actual lamp head is held or that in the lamp head is integrated.
  • An elastic headband is then on this carrier element attached that a user slides over his head to the headlight to attach to the head.
  • the lamp head is then powered by the voltage in the elastic headband with the support element against the forehead of the User drawn and pulled by this train in a more or less stable position relative to the forehead and thus the head of the user held.
  • the carrier element is often formed by a plate, whose dimensions correspond approximately to those of the lamp head.
  • headlights are for very fast movements of the Head may not be due to the mass of the lamp head secure enough in the intended position on the forehead without the to increase the tension exerted on the headband disproportionately.
  • the present invention is therefore based on the object of a headlight to provide that pleasant even over a long period of time is wearable on a user's head while at the same time fitting well.
  • the headlight according to the invention comprises a lamp head for Shot of a lamp, the two opposite one another Has tabs arranged on the sides and connected to the lamp head, on which an elastic headband of the headlight for attaching the Headlight can be attached to a person's head and which are so flexible that their shape when attached to the head by the tension of the Headband is adaptable to the shape of the head.
  • the lamp head of the headlight according to the invention is used for recording at least one lamp, by means of which light can be generated, the can then be emitted by the lamp head as a light beam.
  • Illuminants can be, for example, incandescent, halogen or Act krypton lamps, but preferably LEDs are used that are lower compared to the emitted light output Have energy consumption than the previously mentioned lamps.
  • a imaging device for example a reflector and / or a lens, be provided, by means of which is emitted by the lamp Light the light bundle of the lamp head can be formed.
  • a imaging device for example a reflector and / or a lens, be provided, by means of which is emitted by the lamp

  • Become several Bulbs used can be used for some of the bulbs common imaging device, for example a reflector, or also a separate imaging device for each lamp, for example a lens may be provided.
  • the tabs Due to the tension in the elastic headband, which suitably one has a smaller circumference than a user's head, the tabs at least partially, preferably with their free ends, against the user's forehead pulled and then at least partially this one.
  • the flexibility to at least partially deform the Tab at a desired minimum tension of the headgear is necessary by choosing the material and the shape and in particular a cross section of the tabs can be influenced.
  • the lamp head is therefore not only with an investment area between pulled the tabs on a user's head. Rather serve too the preferably flat tabs at least partially as further contact surfaces, so that on the one hand over the between the tabs lying contact surface does not need to be transmitted a large force and the tension in the elastic headband can be kept lower can. This increases the comfort for a user. In particular pressure peaks are less easy to adjust, which increases comfort could affect.
  • the illuminant is basically arranged in the lamp head his.
  • a battery container two arranged on opposite sides of the battery container and is connected to this tab provided on which Headband is attachable and are so flexible that when attached to the head whose shape is due to the tension of the headgear to the shape the head is customizable.
  • the battery container can by a corresponding, particularly preferably partially coiled, connecting cable be connected to the lamp head.
  • the comparatively heavy ones Batteries can, for example, on the back of a user's head be worn, so that a better weight distribution on Head of the user results.
  • the free ends of the tabs be a distance of have at least 7 cm.
  • a wide headband is usually used here by a given force on a larger one Distributes area and reduces the pressure on the user's head can be. It is therefore preferred that the tabs each have slot-shaped openings through which the headband can be guided. In this way, a wide headband is easy on the tabs fixable. In particular, it can through the slot-shaped openings just be pushed through to then on other parts of the lamp head or, if available, the battery container or with its ends to be connected.
  • a height of the opening is particularly preferred selected according to the width of the headband, so that in Essentially a form fit between the headband and the opening if this is inserted into the slot-shaped opening, results a particularly favorable power transmission between the tab and the Headband, which ensures a particularly safe positioning of the lamp head is made possible.
  • the slots are particularly preferred in a flat area of the tabs with a large slot depth. This results in good power transmission to the headgear and a large contact surface of the tab on the head.
  • the lamp head and / or the battery container has a housing which is at least partially surrounded by a jacket is enclosed in an elastic material on which the tabs are trained.
  • the housing is preferably made of a rigid Material formed that occurs in those that occur during normal use Forces not or only slightly deformed.
  • the housing can serve to hold the lamp and continue to do so still include the imaging facilities mentioned above or also include.
  • the case can be a compartment for one or more batteries or a rechargeable battery that includes a movable cover can be covered.
  • the preferably one-piece jacket is at least partially so close to the housing that a good transmission of when wearing the headlight according to the invention normal forces between jacket and housing without substantial relative movement between the housing and the jacket is possible.
  • the lamp head can be very easily or battery container provided in the area of the Housing can still be rigid.
  • fastening devices by means of which the tabs on a housing of the Lamp head or the battery container can be attached, for example Hinges to be avoided.
  • the coat can be used as Protect against impacts.
  • the jacket only needs the housing partially enclose and can have, for example, an opening, through which light can be emitted in the case of the lamp head or in In the case of the battery container, a battery can be inserted into a battery compartment.
  • the jacket in one Area has an opening in which the housing on the head of the User is present, since the investment area is independent of the properties of the elastic jacket can be designed.
  • the jacket Housing on the when not in use by a user its forehead adjacent areas except for openings for dispensing Completely encloses light.
  • the coat can also be used as Seal the housing against water entering from outside.
  • the battery container has a battery lower part and one it is pivotable on the lower part of the battery housing particularly preferred that the jacket the battery housing lower part encloses that it simultaneously functions as a seal between the lower part of the battery housing and the cover of the battery container.
  • the jacket can be made of any elastic material be formed, the elasticity of which need only be so great that the Lash through the tension of the headgear to the shape of a head Are customizable.
  • the jacket be made of an elastomeric material is formed.
