Description

The invention relates to a luminaire with a, operated with liquid fuel light source, the movable Stabdocht one end in a fuel storage and the other ends in a combustion chamber, wherein a main tank is provided for the fuel, which is connected to the fuel storage, and the liquid level of the Fuel is located in the fuel storage below the liquid level of the fuel in the main tank, and the fuel storage is associated with a level control valve for the, flowing into the fuel storage fuel.

The AT 513 817 B1 discloses a serving as a grave light lamp with a fuel source operated with liquid fuel, the wick ends at one end in a fuel storage and the other end into a combustion chamber, wherein a main tank is provided for the fuel, which is connected to the fuel storage, the fuel storage a level control valve for is assigned, which is flowing into the fuel storage fuel. The wick is designed as a Stabdocht. Furthermore, a height-adjustable relative to the wick flame suppression sleeve is provided which releases an adjustable combustion surface of the fixed anchored wick.

In the following shows the DE 203 125 A a luminaire according to the preamble of claim 1.

In addition, from the AT 266 741 B a grave lantern with a trained as a candle burner for liquid fuels. A arranged within a lamp housing directly above a housing base forming a fuel reservoir burner consists of a Runddocht receiving burner tube which is provided at its upper end with a coarse thread, which is followed by serving as a safeguard against twisting and as a guide for Höhenversteilbarkeit square. The burner tube is surrounded by a candle representing, via a gear transmission from the outside rotatable cylinder, wherein the protruding from the cylinder wick end is covered by a provided with feet perforated cap whose feet engage in an annular groove provided at the upper end of the cylinder.

Finally, the shows DE 199 652 A a gasoline lamp with a rotatable but non-displaceable nut for raising and lowering a wick tube. The interior of the unscrewable housing surrounding a wicket container, surrounding the wick tube, communicates firstly with the gasoline container through openings in the bottom, secondly with the wick through openings in the wick tube, and thirdly with the flame through channels in the nut surrounding the wick tube.

The invention has for its object to provide a luminaire of the type mentioned, which has an additional functionality that ensures easy to bewerkstelligende ignition and has a cost-effective structure.

The object is achieved in that a movable Stabdocht is equipped with a thread and certain areas with a moisture-insulating coating, the Stabdocht extends with its lower, uncoated and absorbent end of the wick surface in the fuel storage and the opposite, also uncoated wick end the Size of the combustion surface by turning the wick thread releases.

The subclaims represent advantageous embodiments of the invention.

In the present lamp, the controllability of the flame is not achieved by a moving flame restriction sleeve, but the Stabdocht is displaced in a firmly anchored throttle sleeve. This is for a comparison with the well-known from the prior art, a reduction of required components and, on the other hand, the fuel flow in the Stabdocht, so the wick body, moisture-isolated encapsulated and the Stabdocht protrudes only with its absorbent end part, on the one hand for refueling at the bottom Wick side in the fuel level controller with fuel storage, and is exposed at the opposite end to a also in a suction and evaporable carrier material without moisture insulation executed evaporator head of Stabdochtes to flame on the wick surface.

The absorbent ceramic Stabdocht is completely glazed except its wick evaporator head and its fuel receiving section and executed at its ends moisture evaporating or moisture-absorbing in a raw ceramic state. Due to the smooth surface of the glazed screw thread, the frictional resistance during the wicking movement for adjusting the wick evaporation surface and thus regulating the flame size as well as the opening and closing of the level control valve is reduced to a minimum. The flame retardation sleeve is stably connected to power supply lines for the heating coil and the ignition pins to the light tube. When the light tube is pushed out of the combustion chamber and the tube is pushed into the combustion chamber, the rod wick slides through the funnel shape of the wick ignition device. and Flammendrosselungshaube out easily or accurately back into it, so that the Zündungsstifte are in the correct distance to the Wickverdampfungsoberfläche.

It is opened with a functional movement at the same time on the one hand by the screwing up the Stabdochtes the inflow valve to Stabdocht and this supplied with fuel, on the other hand is pushed through the screwing down of the Stabdochtes and the Stabdocht further and further into the throttling sleeve after the calibrated Betriebszeiteinstellskala the combustion surface on Stabdocht more and more enlarged. If the end of the operating time is desired before fuel consumption, then the Stabdocht is screwed back into the Brennstoffzuflussabsperrventil, and at the same time the flame is reduced again, so that with the extinguishment of the flame of the wick body is in a dry storage state.

To ignite the flame at the Stabdocht the Wick combustion surface is screwed to its maximum flame size in a wick ignition hood, so that the heat of the heating coil through the superimposed metal surfaces can transfer particularly effective on the wick surface for evaporation of the liquid fuel. After the ignition process, the wick combustion surface is returned to the desired flame size and operating life.

The manually adjustable luminaire can also be remotely started up and monitored with a replaceable luminaire tube equipped with electromechanical and electronic control components. So that the owner can obtain information about the current fuel supply for accessing the control unit of the luminaire, tank filling height sensors are arranged on the control unit along the guide rail to the tank space, which can detect the liquid level in the tank, for instance by an optical measuring method, and with a desired remote inquiry For example, the authorized user can transfer the data to the display monitor of their smartphone.

With the non-burnable and made of a ceramic material, for example Stabdocht not only technically complex lights can be produced with a high ease of use and unique reliability, which are determined by their slightly higher cost and refilling with liquid fuel primarily for an environmentally friendly reusability, rather Thus, the consumer can also be offered a very inexpensive luminaire, which has the same high safety features as the comfort luminaire, but can be produced for use as a disposable luminaire or as a non-adjustable refill luminaire.

In the example designed as a disposable lamp, the fuel supply is accomplished by the Stabdocht characterized in that the user can be opened by a rotational movement of the Stabdochtes, as in a thumbscrew, the fuel level control valve and closed again. Since the wings of the Stabdochtes moisture-insulated, or are glazed at a ceramic Stabdocht, a clean handling is guaranteed when touched. A safety tear-off strip fixes the screw thread during transport and storage of the lamp against unwanted threaded lock, guarantees the user the original filling and indicates during commissioning the exact position of exactly one wick turn performed. In the printed operating instructions, the user learns that commissioning of the luminaire is accomplished by a complete turn to the right of the bar throats over the wings of the bar thief and then after about one minute the bar wick is moistened with liquid fuel for the ignition.

The luminaire offers the possibility of producing, in particular, one-way luminaires of short to very long operating times due to the unbound amount of liquid fuel, which thus do not require a more complicated design and also do not adversely affect the operational safety in any way. Longer operating times can also be achieved, for example, by attaching a flame restrictor plug-in sleeve with which different operating times can be set depending on the throttling size due to the smaller flame size.

For the use of the lamp as a grave light outside of lanterns can be used to protect against the weather and a ventilated operating cover, such as metal or refractory glass, which would be a particularly effective light emission would benefit. In a further embodiment, the operating cover can also be equipped with a flame-retardant sleeve, which allows an operating time control according to a combustion duration scale.

When using the light for special festivities, there is also the technical possibility aufzustecken on the Stabdocht of absorbent material such as clay decoration figures or say signs with a heat-emitting neon sign that further absorb the fuel liquid from Stabdocht and thus lead to a decorative and larger flame formation ,

For a clean disposal, the cover removed during the commissioning of the luminaire and attached to the luminaire floor is returned to transport the luminaire back, thus protecting against possible contamination of the environment. Due to the simple design of the lamp, the two main components of the lamp, namely the light housing made of plastic and the Stabdocht from a ceramic to another for raw material recovery can be easily separated from each other, in which only the Stabdocht is completely unscrewed from the lamp housing and both parts are sent separately for disposal.

The invention is explained in more detail below with reference to embodiments with reference to the accompanying drawings.

The designed as grave light luminaire includes a main tank 12 with translucent walls partially surrounding a liquid fuel light source, the rod wick 1 at one end in a fuel storage 28 and in the other end in a combustion chamber 25 empties. In addition, the main tank includes 12 one, into the fuel storage 28 outflowing cycle tank 11 for the fuel.

The fuel storage 28 is a level control valve 8th for that in the fuel storage 28 associated with incoming fuel, wherein the main tank 12 is sealed gas-tight, and the fuel storage 28 via an air supply duct 6 with the combustion chamber 25 connected is. The liquid fuel can as long as from the main tank 12 over the cycle tank 11 in the fuel storage 28 infuse until the liquid level in the fuel storage 28 the inlet opening of the level control valve 8th Completely closes, and thus a backflow of air from the fuel storage 28 in the cycle tank 11 and the main tank 12 via the inlet opening of the level control valve 8th is prevented. If the fuel level in the fuel storage decreases 28 under the top edge of the fuel tank 28 outflow opening of the level control valve 8th From, can air from the fuel storage 28 through the inlet opening of the level control valve 8th in the cycle tank 11 and the main tank 12 overflow, so as long as fuel in the fuel storage 28 flows down until the liquid level in the fuel storage 28 at least again at the level of the upper edge of the inlet opening of the level control valve 8th lies.

The main tank 12 is the present cylindrical combustion chamber 25 at least for the most part, being in the combustion chamber 25 a light tube 13 is inserted, which is a visible surface 15 can have. The visible surface 15 for example, a visible surface design 36 with symbols. The light tube 13 is to form a ventilation gap 16 to the inner surface of the main tank 12 at least in sections by latching elements 17 spaced, wherein the rear ventilation gap 16 into a fresh air supply duct 21 empties.

leadership vaults 26 in guide grooves 28 slide, stabilize the insertion of the light tube 13 in the combustion chamber shaft 25 , At the same time, the cyclic tank connection valve remains for continuous operation of the luminaire 18 through the valve opening curvature 19 open and it can be used up the entire tank contents without interruption. By removing the light tube 13 from the combustion chamber shaft 25 and the new, reverse insertion of the light tube 13 in the combustion chamber shaft 25 slides the valve closing buckle 20 on the cycle tank connection valve 18 on and with supporting back pressure of the valve closing pressure edge 31 the fuel flow becomes the cycle tank 11 by closing the cycle tank connection valve 18 interrupted for several cycle operations. This functional mechanism is only used for luminaire tubes 13 without control unit 55 as with light tubes with an electronic control unit 55 the cycle tank connection valve 18 always remains open and the fuel supply for cycle operations via the level control valve 8th be controlled electromechanically.

To ensure adequate supply of the flame with combustion air, is also the combustion chamber 25 in the area of the combustion chamber floor with the fresh air supply duct 21 connected. In addition, the fresh air supply channel forms 21 also a leading out of the lamp rainfall, can be derived on the inside of the lamp rainwater entering in a simple manner. The fresh air supply duct 21 ensures thereby over the rear ventilation gap 16 also for being in the main tank 12 existing fuel is not overheated.

To the wick 1 to get to the light tube 13 using grip grooves 45 upwards over an easily surmountable fixing curvature 29 until the larger sliding resistance of the fluorescent tube discharge curvature 30 lifted off and in the raised position by means of easily surmountable, smaller fixing curvature 29 be fixed, after which the combustion chamber 25 directly accessible from the front.

The light tube 13 may preferably consist of a heat-resistant material which is transparent, colored in the desired color, but also on a visible surface 15 with a visible surface design 36 be designed arbitrarily. An improvement in luminosity can be achieved by the luminaire tube 13 with a radiation-reflective coating 14 is provided. To inadvertently disconnect main tank during transport 12 and lighting tube 13 To avoid, the light tube can 13 through a luminous tube discharge vault 30 latching and through a combustion chamber sealing foil 43 on the light in the surrounding main tank 12 be used.

In order to be able to set the flame size as accurately as possible to the desired operating time length according to a day scale, is in the combustion chamber 25 one the wick 1 comprehensive flame retardation sleeve 3 provided, which at the same time to ignite the wick 1 as a wick ignition hood 59 is executed and through the throttle sleeve holder 2 stable with the arc tube 13 connected is. By means of a thread 7 can the wick 1 by a rotary movement on the dial 10 in a linear motion in the flame choke sleeve 3 be inserted, so that the wick evaporator head 73 further and further out of the flame retardation sleeve 3 protrudes. By a catch spring 39 becomes an unintentional adjustment of the burn duration scale 5 and the alignment mark 23 set operating time avoided. A light intensity indicator bar LA as well as a small and big flame symbol 42 on the burning time scale 5 show the course of the light intensity control.

The factory calibration of the flame size on the Brenndauerskala done on the one hand by a first, firm screwing the wick body of the bar-dowel 1 to close the level control valve 8th and then touchdown of the dial 10 with a zero operating time display of the combustion duration scale 5 and simultaneous fixation to the wick body 1 with the calibration fixation pressure points 4 , The second component is the flame retardant sleeve 3 , also as a wick ignition hood 59 , with the throttle sleeve holder 2 in a defined vertical distance to the wick 1 when assembled on the wall of the luminaire tube 13 be attached.

Thus, when using the luminaire in a manual operating time setting with the standard tube, without electromechanical components and control unit 55 , the illumination duration of individual individual illumination intervals is freely adjustable, includes the main tank 12 the over an intermediate floor 38 separated cycle tank 11 , where the cycle tank 11 via a lockable cycle tank connection valve 18 with the main tank 12 , as well as the level control valve 8th with the level-regulated fuel storage 28 connected is. As the flame choke sleeve 3 because of the specification for the burning duration scale 5 always a defined vertical distance to Stabdocht 1 must have and this when turning the lamp tube 13 For a continuous lighting operation or a cycle operation would not exist, there is a replaceable light tube 13 for continuous operation and one for cycle operations. It is also possible to have a special lighting tube 13 to use for both operating systems, in which at the light tube 13 a slide switch with latching function is present, with which the flame restriction sleeve 3 Turning the tube to the calibrated height position for the height-adjustable bar wick 1 is brought. An unauthorized access to the light tube 13 as well as on the tank refill pressure seal 68 is not possible before the sale of the lamp, as on the lamp a Brennraumversiegelungsfolie 43 with operating instructions 44 and guarantees the buyer the originality of production.

The lamp can also be outside of lanterns with a cover 33 be operated on the shaft-like combustion chamber 25 is put on. It is when putting on the cover 33 the sealing ring 46 from the recessed grip 35 on the fixation notch 47 deferred so that this the ventilation gap 16 closes and thus protects against the ingress of rainwater. As a result, the cooling air from the rear ventilation gap 16 through cooling air flow openings 48 in the tube interior 13 diverted and can from there via the exhaust ports 34 escape to the outside. The transport of the lamp to and from its place of use is in a carrying case magazine 24 a disposal bag at the bottom of the lamp 37 provided, which allows a comfortable and clean carrying the lamp.

When operating the luminaire with a control unit 55 remains the cycle tank connection valve 18 always open, as individual illumination intervals via the geared motor 53 and one with a sprocket 9 co-operating engine gear 54 and the level control valve 8th being controlled.

The wand wick 1 is the wick ignition hood 59 with a heating coil 60 running heater and flame ignition pins 61 associated with comprehensive ignition device. The wick ignition hood 59 Be on the flame restriction sleeve 3 put on, so that the heat of the heating coil 60 , also reflected radiant heat from the Oberflächenisolierspiegelung 67 , on the metal surface of the flame retardation sleeve 3 can transfer and the liquid fuel of the middle located Stabdochtes 1 can evaporate. An ignition spark 62 the flame ignition pins 61 ignites the fuel gas and thus the flame at the Stabdocht 1 , An infrared sensor 66 monitors both the ignition process and the proper functioning of the luminaire during the entire operating time, as this unattended also via a brightness sensor 56 can control a day / night rhythm. With a solar module 57 will be in the light tube 13 located control unit 55 powered by an accumulator with electricity. The electrical supply to the wick ignition hood 59 on the one hand via the power lines 64 . 65 as well as via the common ground power line 63 for the heating coil 60 and the flame ignition pins 61 ,

For controlled extinguishment of the flame is by screwing the Stabdochtes 1 in the fuel storage 28 with the electric geared motor 53 the level control valve 8th closed and thus the fuel supply from the cycle tank 11 prevented, whereby the flame with the exhaustion of the wick saturation is getting smaller and eventually disappears. The wear-free Stabdocht suffers 1 no damage and retains its original size and feature for further ignition operations on the calibrated burnout scale 5 at.

The control unit 55 is with the geared motor 53 and the engine gear 54 and the wick ignition hood 59 , which is attached to a guide rail 58 connected, so that during a power transmission to the dial 10 a stable storage is given.

For the tank level indicator are along the guide rail 58 at the control unit 55 vertical of the main tank 12 for the fuel stock Tankfüllhöhemesssensoren 81 arranged, which, for example by an optical measurement method, in a remote query information about the fuel level and thus about the fuel supply in the tank room.

The Stabdocht 1 protrudes in its lower, moisture-absorbing part with an uncoated wick surface 69 in the fuel storage 28 into it. The overlying · part of the Stabdochtes 1 has a cone shape that is already moisture-proof coated and thus the level control valve 8th also brings in a matching cone shape for closing. The subsequent thread 7 for adjustment is also with a lubricious coating 71 provided so as to cause on its friction surface a possible low frictional resistance. Finally, the moisture-insulating coating goes over the further wick body, past the calibration-fixation pressure points 4 , to the wick evaporator head 73 , which is again to bring the vacuumed up liquid fuel for evaporation and flame formation without moisture insulation. To the wick evaporator head 73 around is the wick ignition hood 59 with the heating coil 60 and the flame ignition pins 61 ,

In a particularly user-friendly embodiment, in this functional system, both the flame size and combustion duration setting, as well as the filling of the fuel storage 28 made from the front of the luminaire. Here, the flame size or the burning time and the opening of the level control valve 8th by a single rotation of the thread 7 done at the same time. The Stabdocht 1 moves up or down depending on the direction of rotation and thus controls not only the fuel supply in the fuel storage 28 but also the free size of the surface of the wick evaporator head 73 with the help of fix on the light tube 13 attached wick ignition hood 59 and simultaneous flame retardation sleeve 3 ,

It will open 7 Referenced. The designed as a disposable lamp comprises a housing 75 with the main tank 12 , in the partially moisture-insulated Stabdocht 1 with thread 7 and bar wicker 74 is completely screwed in so that the coated wick surface 70 at the level control valve 8th firmly attached and no liquid fuel from the main tank 12 in the fuel storage 28 can flow into it. A gas pressure bubble 32 allows expansion and contraction of the main tank 12 located fuel with temperature changes and thus favors the pressure adjustment when opening the level control valve 8th , A trained as a kind of protective cover cover 33 protects the bar wick 1 for transport and storage.

According to 8th the commissioning of the one-way light is shown, in which the cover first 33 is removed and plugged onto the lamp base for the subsequent light disposal. It is done by hand on the bar wicker 74 a full bar wicket turn to the right, causing the wand wick 1 over the thread 7 is unscrewed and the coated wick surface 70 the level control valve 8th releases liquid fuel from the main tank 12 in the fuel storage 28 inflow and from the uncoated wick surface 69 over capillary tubes 72 from the rod wick 1 can be included. The exact position of a Stabdochtumdrehung is thereby from a safety tear strip 77 indicated that after a wick turn again has its full length, but is damaged by a demolition point. After a short wait for the wick saturation, the wick evaporator head can 73 be ignited, the flame size of the coated wick surface 70 to the uncoated wick surface 69 is determined. If there is any remaining fuel in the main tank when disposing of the lamp 12 , conversely, for commissioning the Stabdocht 1 over the bar wicket 74 again over the thread 7 screwed in to the left and thus through the coated wick surface 70 the fuel supply to the fuel storage 28 via the level control valve 8th closed. The cover 33 From the luminaire floor can then be placed again to protect against contamination on the lamp.

For the use of the lamp on graves outside of grave lanterns, the lamp can provide a weather-protecting operating cover 82 be screwed on. This has the advantage that the fuel supply quantity is not tied to the interior size of a grave lantern and lights with extra long operating times can be freely placed on the graves. The to an edge of the housing 75 sloping combustion chamber floor directs any penetrating rainwater through the fresh air supply and storm water drainage openings 83 to the outside. The exhaust gases escape through exhaust ports 84 in the plant cover 82 ,

In another embodiment, the one-way light with a special operating cover 82 with a built-in flame restriction sleeve 3 according to a burning time scale 5 operate. This is when commissioning the one-way light as the first wing having Stabdocht 1 until its calibration mark 40 unscrewed to the combustion chamber floor. The operating cover 82 with flame retardation sleeve 3 comes with its asymmetrical housing screw thread 76 having a fixed rotational resistance, with the Einstellsichtfenster 85 so far on that Gehäuseschraubgewinde 76 , a Gehäuseschraubgewinde, screwed up until the approximately equal ignition opening 41 in the housing screw thread 76 and the setting window 85 superimposed and so the way to Stabdocht 1 release. After firing the Stabdochtes 1 with a gas lighter or an extra-long match is made by further turning the operating cover 82 , which can also be referred to as a protective cover, the desired operating length on the Brenndauerskala 5 in the settings viewport 85 through the display of the lamp thread edge 75 adjusted and at the same time depending on the operating time setting the ignition opening 41 at the housing screw thread 76 at least partially closed again. The omission of the wet protective cover roof results in a continuously variable lamp for operation in an already weatherproof lantern.

To 9 In the top view of the light, in particular, the security tear strip 77 with the breakpoint 78 shown at the start-up of the lamp by a Wickrechtdrehung on the Stabdochtflügel 74 is torn off and after a Whole turn of the wick to control its full length again. The operating instructions 44 informs the consumer about the commissioning of the luminaire.

According to 10 further applications of the lamp are shown, which should illustrate additional decoration options. On the wick evaporator head 73 are for example decorative flame sleeves 79 attachable, which may also be provided with a heat-active luminous color, to heat under action as a spell 80 to light up. Thus, the disposable lamp is also suitable as a decorative gift item. Also different sized Flammendrosselungsaufsteckhülsen 22 let yourself on the Stabdocht 1 attach, so with a smaller flame size, the operating times can be extended arbitrarily. For a weather-proof use of the luminaire, a heat-resistant, ventilated operating cover can be used 82 be screwed onto the one-way light. In a special design, this operating cover 82 also with a flame retardation sleeve 3 and a burning time scale 5 be equipped so that through a Einstellsichtfenster 85 also desired operating lengths according to a combustion duration scale 5 can be adjusted. For the refillable light can also a weather-protective cover 33 for use outside lanterns. When attaching this operating cover is a in a recessed grip 35 located sealing ring 46 in a fixation notch 47 pushed up so that the rear ventilation gap 16 is closed and this is protected from rainwater entering. Heated cooling air from the ventilation gap 16 can then through Kühlluftdurchströmöffnungen 48 and the exhaust slots 34 the cover 33 get outside.
