Definitions

  • the invention relates to a portable flashlight with a lamp housing and arranged on the lamp housing handle.
  • this housing has two light exit openings, each of which is assigned a light source and a lens device inside the housing.
  • the respective light source is at least one LED (light emitting diode).
  • the light sources can be arranged together on a printed circuit board for electrical supply and control. This results in a compact flashlight with the realization of search light and work light in a flashlight, with search light and work light each using a separate light exit opening and a separate light source.
  • the construction of the hand lamp is simplified as a whole, whereby this is provided with a printed circuit board for the electrical supply and control of both light sources.
  • the printed circuit board can be arranged on a heat sink.
  • a heat sink may have cooling fins or the like.
  • printed circuit board and heat sink may be connected to a lens holder for holding the lens device.
  • the connection can be made by, for example, that the heat sink is formed integrally with the lens holder, and only the printed circuit board is to be arranged accordingly on the heat sink.
  • Other possibilities for connecting the printed circuit board and heat sink with the lens holder are also possible.
  • the lens device can be designed in different ways.
  • the lens device may have two lenses each associated with one of the light exit openings. That is, the one 2
  • Lens with associated LED allows the search light and the other lens with associated LED allows the working light.
  • the lenses are arranged at different distances to the respective light source and held by the lens holder.
  • the arrangement need not be static, but may be variable to change the focus.
  • the lens holder can be detachably arranged inside the housing.
  • Such a detachable arrangement can be carried out, for example, by screwing the lens holder into the housing or by other fastening measures.
  • the lens holder with lenses, heat sink and printed circuit board is designed as an exchange module. That is, the entire replacement module is both easy to use in the flashlight and possibly interchangeable. Furthermore, the corresponding replacement module can be composed of individual parts, s. the above embodiments and in particular printed circuit board, heat sink and lens holder and held by the lens holder lenses as individual parts.
  • a heat conducting device such as heat conducting foil, heat paste or the like may be arranged between them.
  • a distance between the lens and the associated light source can be fixed. This can apply to both search light and work light or even only one of these lights. In other words, with such a fixed distance, focusing is not necessary, but the lens is in each case arranged such that, for example, the corresponding light source is already arranged in the focal point of the lens.
  • the flashlight can then be recharged via a corresponding charger.
  • the battery capacity indicator light can be used as the battery capacity indicator light.
  • the hand lamp is used directly, there is an indication of a battery capacity in a critical area in which, for example, search light or work light operate in the flashing mode. Then the user of the flashlight can perform a corresponding charge.
  • the flashing mode may include a continuous flashing or even a brief flashing.
  • a brief flashing there is accordingly only a brief interruption of the search light or work light which otherwise operates in continuous operation.
  • the printed circuit board has already been stated that this is designed for electrical supply and control of the corresponding light sources.
  • Such a controller may include a monitoring of the flashlight, so that, for example, in particular after switching on the flashlight, a self-test is feasible.
  • an automatic reduction of the light intensity takes place, which, for example, is possible if a user of the flashlight has become accustomed to a diminished ambient brightness after a certain time by adapting his eyes.
  • the lamp housing can be formed from an upper lamp head housing part to a lower battery housing part, which are in particular pivotally connected to each other.
  • the lamp head part could be pivoted relative to the battery housing part without the battery housing part taking part in the pivoting movement.
  • This can be realized by a pivot axis between the two housing parts or by a gimbal connection between them.
  • FIG. 1 is a perspective view of a portable handheld light according to the invention from one side and
  • FIG. 2 shows a longitudinal section through the flashlight according to FIG. 1.
  • FIG. 1 shows a perspective side view of an exemplary embodiment of a portable hand lamp 1 according to the invention.
  • This has a luminaire housing 2, which is composed of an upper lamp head housing part 19 and a lower battery housing part 20. Between the two housing parts 19, 20 a pivot bearing 21 is arranged, which allows pivoting of the two housing parts relative to each other.
  • a corresponding number of batteries and in particular rechargeable batteries is arranged. Recharging can be done by means of a charger.
  • a handle 3 is arranged, which allows a carrying the hand lamp 1 by a user.
  • a switch 22 is arranged in the region of the handle 3, which allows a switching on and off of the portable flashlight 1 in a simple manner.
  • the light exit opening 4 allows, for example, search light and the light exit opening 5 work light.
  • FIG. 2 shows a longitudinal section through the portable hand lamp 1 according to FIG.
  • Battery housing part 20 pivotally connected to the upper lamp head housing part 19.
  • two light sources 6, 7 are arranged, which are each formed by an LED 10, 11.
  • the two LEDs are spaced apart from each other together on a printed circuit board 12. This is used for electrical supply and control not only of the LEDs, but also other parts and applications of the portable flashlight. 1
  • the printed circuit board 12 is arranged on a heat sink 13, wherein between these a heat conducting device 18 in the form, for example.
  • a heat conducting foil or thermal paste can be arranged.
  • Printed circuit board and heat sink have essentially the same dimensions.
  • a spacer 23 may be arranged on the side facing the light exit opening 4, 5 which is annular and at its end remote from the printed circuit board holds a lens device 8 in the form of two lenses 15 and 16.
  • the two lenses 15, 16 are arranged at a different distance from the respective light source 6, 7.
  • the combination of lens 15 with LED 10 as the light source 6 serves to provide an add-on light and the combination of lens 16 with LED 11 as a further light source 7 to provide a working light.
  • a lens holder 14 For the attachment of spacers 23 and thus also printed circuit board 12 and heat sink 13 within the housing interior 9 is a lens holder 14. This is within the lamp housing 2, for example. Screwed with a screw 25. By the corresponding spacer 23, a distance between the corresponding lens 15 or 16 and associated light source 6 or 7 is predetermined. Manual focusing is not necessary.
  • Light sources 6, 7, lens device 8, printed circuit board 12, and heat sink 13 may be summarized in a replacement module 17, so that they are overall handled and interchangeable. Another part of the replacement module may be the lens holder 14. D. h., The entire exchange module can be used by means of the lens holder 14 within the flashlight 1 and can be arranged there in the appropriate position.
  • one of the light sources 6, 7 fails while it is currently in use, it is possible, in particular, to switch over automatically to the other light source.
  • the search light and thus the light source 6, can be converted to working light and light source 7 P2013 / 003603
  • At least one light source can be used as a battery capacity indicator light.
  • the battery capacity of the batteries 24 drops below a predetermined desired value
  • one of the light sources can be switched to a flashing mode.
  • the flashing frequency may be in relation to the remaining battery capacity, so that, for example, a faster flashing takes place with a further decrease in the battery capacity.
  • This flashing can also be done when using the flashlight, which in this context is advantageous if the flashing is done only over a period of time and not as a continuous flash.
  • the printed circuit board and the electronics arranged thereon it is still possible to carry out a self-test, in particular after switching on the flashlight.
  • This may include, for example, the battery capacity, the functionality of the light sources and also reviews of other parts of the flashlight.
  • the portable hand lamp according to the invention a plurality of LEDs for each of the light sources 6, 7 are used. This also applies to only one light source. Furthermore, it is conceivable that, at least prior to insertion of the corresponding exchange module 17, the focusing of the respective light source is changed by changing the distance of the lens to ⁇ ordered. Furthermore, it should be noted that the corresponding light exit openings 4 and 5 may be closed by a transparent pane ⁇ nen, for example, to protect lenses or other parts of the portable flashlight inside the housing from shock or contamination.
