Definitions

  • the present invention relates to a stray light attachment for a portable lamp, in particular a flashlight or headlamp, which allows a glare-free, spatial illumination of the environment, for example in a tent, camper, caravan or in a cave.
  • camping lights which have a pedestal with a receptacle for batteries, and a light source and mounted on the light source, fixedly connected to the base, transparent diffuser attachment having at least one integrated reflector element.
  • These lamps produce a glare-free, diffused light, which ensures an even illumination of the environment.
  • camping lights are relatively large and therefore relatively heavy.
  • Known in the art include special caps for commercial, translucent or transparent water bottles, in which several solar-powered LEDs are integrated.
  • a liquid-filled water bottle can be converted into a camping light, the emits a diffused light, which is suitable for spatial illumination in the vicinity, for example in the interior of a tent.
  • the standard equipment of a hiker or camper usually includes a flashlight or headlamp, which is often used for indoor lighting in a tent and thus also provides an alternative to a camping light.
  • a conventional pocket or headlamp when used as a campground light is that it generates a directional light beam of one or more LEDs and therefore achieves only a small spatial illumination.
  • the light beam is very dazzling and therefore unfavorable for use in the interior of a tent.
  • modified headlamps are known in which for the generation of stray light in the vicinity of a substantially planar scattering lens such as a closure lid from a lateral parking position can be pushed out immediately before the light source, rotated or folded. This reduces the direct glare of the light beam and achieves a slightly better room illumination.
  • the LEDs produce a more or less wide beam of light due to their lowered position in the lamp housing despite the upstream scattering lens.
  • the light output is not optimal due to the lying in front with the front of the lamp housing in a plane scattering lens.
  • Object of the present invention is therefore to provide a system that makes it possible, a commercially available portable lamp, in particular Flashlight or headlamp, in a simple and cost effective way to transform an effective camping light, which offers a strong light scattering with maximum light output and therefore for uniform spatial illumination mainly in the vicinity, such as the interior of a tent or caravan can be used.
  • the stray light attachment 1 comprises a transparent, sleeve-shaped in a first embodiment Housing 2, with a first end 3 and a second end 4, wherein the first end 3 is closed by a closing element, in particular a cap 8, and together with this forms a head portion 5, and the second end 4 is open and a foot portion. 6 forms.
  • the end member at the first end 3 may be formed with the housing 2 as an integral whole or as a separate part to be connected to the housing.
  • the housing itself can also be designed in the form of a one-piece sleeve or as a two-part or multi-part set of individual parts, which can typically be connected to one another by snap fasteners.
  • the scattered light attachment has a reflector element 7 designed as a diffuser mirror.
  • sleeves or “sleeve-shaped” is here indicated the generally elongated outer shape of the housing open on one side. But even deviating forms, such as a spherical or diced shape of the possibly multi-part, in the ready-to-use state, however, always unilaterally open housing, according to the invention should be mitumutzt of these terms.
  • the scattered light attachment is in the simplest case in that it is slipped over a standard lamp, typically a pocket or headlamp, loosely over it, for use in the outdoor area, however, is an attachment to the corresponding lamp advantage.
  • a lamp should be understood herein also a conventional light bulb with associated socket or associated lamp base, the expression light bulb here representative of all in a version or a Socket screwed bulbs with external thread is, for example, energy-saving bulbs with spiral fluorescent tube.
  • the first end 3 of the housing is the one which, in the state ready for operation on a lamp, is situated at a predetermined distance of the light source, which is dependent on the housing length.
  • a cap which is inseparable from the housing, for example in one piece, connected or optionally removable again, which on the one hand carries the reflector element 7 and on the other hand completely closes the housing at this point.
  • the reflector element 7 is connected to the inside of the cap 8 with this fixed or detachable, which allows the possibility of replacement in case of damage in the latter case.
  • the reflector element 7 of the light source 14 is in any case opposite such that the light beam or light cone exiting the light source 14 hits the reflector element 7 centrally on the convex surface and is reflected by it as evenly as possible in all directions.
  • the cap 8 may be constructed in two parts and comprise a first, approximately annular part 8a, which carries the reflector element 7, and a second part 8b, which is designed as a lid and via at least one connecting element, preferably a connector, releasably connected to the first part 8a.
  • This structure makes it possible, inter alia, to remove the reflector element in case of contamination or possible damage in a simple manner, clean or cost-effective replacement.
  • the detachable connection between the one- or two-part cap and the housing can be done in different ways, for example by a quick release such as a snap, clamp, screw or plug connection.
  • the stray light attachment according to the invention is tuned for the purpose of use with commercially available pocket or headlamps with its open end 4 on the geometry and dimensions. As flashlights herein are essentially to understand rod-shaped flashlights.
  • the portable lamp in particular pocket or headlamp
  • the portable lamp is such a model that can be placed on a flat surface, at least in a stable, at least self-standing manner, and can radiate its light vertically upwards.
  • a scattered light attachment according to the invention can be used, which has an inner diameter at the end 4, which exceeds the largest outer diameter of the lamp and therefore can simply be slipped over it loosely.
  • the inventive stray light attachment on the lamp be reversible, i. again removable, can be attached to allow its use in any position of the lamp, so for example, in a hanging position.
  • the scattered light attachment in the foot region 6 of its open end 4 has fastening means which cooperate with corresponding fastening means of the lamp and which allow it to be reversibly connected to the lamp, for example according to Art a quick release, in particular a snap, clamp, screw or bayonet-type rotary closure.
  • the scattered light attachment according to the invention is adapted to the lamp geometry in such a way that it can be slipped over the light exit-side upper side of the headlamp and connected to it by light pressure until overcoming a snap lock mechanism.
  • such attachment can also be provided via another type of quick release, as mentioned above.
  • the rotary closure can also be designed in the form of a bayonet-type rotary closure, for example such that the scattered light attachment in the foot region 6 of the end 4 has at least one point of its circumference, advantageously at least two points, an outwardly directed collar.
  • This collar cooperates with at least one arranged on the lamp housing or lamp base, corresponding, circularly curved retaining rail by being screwed under this and clamped therein or snaps into place after overcoming an obstacle in the sense of a snap closure and is fixed.
  • the sleeve of the housing 2 is made in two parts, depending on the embodiment, for example with or without a hinge at the end 3, it can also be applied to a flange region of the lamp base and stably clamped and fixed, for example, by means of at least one clip fastener on the lamp base.
  • the housing halves held together either by the hinge or eg by plug or snap closures.
  • the distance between the light source 13 integrated in the lamp 9 and the reflector element 7 should be at least 1 cm when the stray light attachment is positioned in the ready position. As a rule, this distance is about 1 to a maximum of about 20 cm, but for most applications, a scattered light attachment whose length gives a distance of the reflector element from the light source in the range of about 5 to 10 cm is sufficient.
  • the light source 13 which usually consists of one or more LEDs but may of course also comprise a conventional light bulb
  • the directed light beam is deflected by the reflector element 7 in lateral directions, penetrates the transparent or translucent, for example frosted, walls of the housing 2 and thus generates a diffuse, even and glare-free illumination of the environment.
  • the open end 4 of the housing which typically has a rectangular, rectangular, oval, ellipsoidal or similar, in particular polygonal, possibly also round, cross-section, for the purpose of releasably securing the stray light attachment on a Headlamp be formed approximately complementary to the shape of a saddle, with broad-side recesses in the form of an inverted "U” and longitudinal, deeper-drawn side parts of the housing (see Fig.1 to 3 ), which cooperate with ready mounted stray light attachment with the base region of the headlamp, for example by clamping action, and typically rest on this.
  • the housing 2 in order to ensure a stable resting of the scattered light attachment on the headlamp, the housing 2 according to a preferred embodiment in the foot region 6, at a predetermined distance to the lower edge of the open end 4 of the two longer side parts, at least one disposed on the housing inner side 11 and inwards pointing, first projection 12 (see Fig. 6 ), which rests on an abutment, typically a corresponding edge, on the light-outlet-side upper side of the headlamp when the headlamp is mounted ready for operation on a headlamp.
  • This at least one, first projection thus acts on the one hand as a spacer for the correct positioning of the housing and on the other hand serves to stabilize the position of the scattered light attachment on the headlamp in order to prevent a possible tilting of the same.
  • the first projection 12 may, for example, in the form of two eck receivingr noses or nipples or in the form of an elongated, running in a cross-sectional plane of the scattered light attachment on the inside of the housing bead, fold or such a bead, bar or protruding inner edge.
  • upper side or "light exit side” is used herein in connection with the headlamp, this refers to the side which has the exit opening for the light beam.
  • a further, inwardly facing, second projection 14 which cooperates in the manner of a quick release, such as a snap closure, with another edge on the top or a side portion of the headlamp and the housing fixed in this manner to the headlamp ,
  • the quick release can also be embodied in another suitable form, for example in the form of a circumferential groove on the lamp, in which the end 4 of the housing 2 can be positively inserted and held either by clamping effect or in turn via a snap lock mechanism.
  • inventive stray light attachments are provided which have at their open end 4 a round cross section with an internal or external thread in the foot area 6 and can be screwed onto the lamp with a corresponding mating thread.
  • bayonet-type fasteners are suitable, wherein the open end 4 of the housing, for example, has a at least a portion, preferably at least two sections of its circumference, outwardly directed collar and screwed with this in a corresponding retaining rail on the lamp and clamped or optionally over a snap mechanism can be fixed.
  • the scattered light attachment in the region of its open end 4 is adapted to the lamp to be equipped with it, as it follows in this area at least approximately the outer contours of the lamp base, the lamp socket or the lamp cap and in this area a widest diameter which is either slightly smaller, equal to or greater than the corresponding largest diameter of the lamp base, socket or the lamp cap.
  • a smaller diameter of the Stray light attachment simply be put under pressure by applying pressure to the lamp and is then held there by clamping action. It consists for this purpose of an at least slightly stretchable material, for example a suitable plastic material.
  • the housing 2 of the scattered light tower With the same size or larger diameter of the open end 4 relative to the lamp base, socket or the lamp base, the housing 2 of the scattered light tower completely over the lamp 9 and then, for example, by means of one, two or more laterally attached to the housing adjusting or adjusting screws the lamp base, socket or the lamp base are fixed by clamping.
  • the housing adjusting or adjusting screws require no mating thread on the lamp, since the adjusting or adjusting screws have external threads and are guided in corresponding, provided with internal thread openings in the region of the open end 4 of the scattered light attachment.
  • These adjusting or adjusting screws can be made of a suitable plastic material and have for easy handling on ribbed or equipped with small wings screw heads. In principle, however, spring-loaded clamping pins or bolts with a latching mechanism can be used instead of the screws.
